What she longed for was not just blood, but other things that could replenish her life force.
"Since you want to replenish your life force, why don't you take it yourself? How about you do it yourself?"
Saint Karina placed Esther's hand in an indescribable place, tacitly approving of her next move.
At the same time, it is also an encouragement.
First, consider Esther as an artificial AI that needs to be charged, that is, an automaton, and Saint Karina's indescribable features can be regarded as a circuit board.
To obtain electrical energy, you first need to repair the broken circuit board using your own methods.
First, when Esther receives a circuit board to be repaired, the first step is to carefully inspect its appearance. If the circuit board has been burned, then before powering it on, it is essential to carefully check whether the power supply circuit is normal, and only power it on after ensuring that it will not cause secondary damage.
The observation method is a type of static inspection method. When using the observation method, you must carefully check whether the power supply circuit is normal, and only turn on the power after ensuring that it will not cause secondary damage.
To determine whether the circuit board has been intentionally damaged, the following aspects should be considered:
① Check if the circuit board has been dropped, causing the corners to deform, or if the chips on the board have been deformed or damaged.
② Observe the chip socket to see if it was forcibly pried open due to the lack of special tools.
③ Observe the chips on the circuit board. If they have sockets, first check if the chips are inserted incorrectly. This is mainly to prevent the operator from inserting the chips in the wrong position or orientation when repairing the circuit board. If the error is not corrected in time, the chips may be burned out when the circuit board is powered on, causing unnecessary losses.
④ If the circuit board has shorting terminals, check whether the shorting terminals are inserted incorrectly.
"Sister Saint Karina...can I have a sip first, just a sip?"
"You drink it."
Saint Karina was neither reserved nor stingy; she generously spread her legs wider and pressed Esther's head down.
"Gudong——Gudong——"
After observing carefully, Esther transformed into Kuafu, saying "I am Kuafu" and taking a sip, immediately drinking heartily.
The sweet spring water gurgled out from the springhead.
She likes to drink plenty of water before doing anything to fill her empty stomach before she can focus on her work.
In fact, circuit board repair requires a solid theoretical foundation and meticulous work skills. Through careful observation, the repairman can sometimes determine the cause of the problem at this stage.
Step 2: Inspect the components on the circuit board for any burnt-out parts. For example, check if the resistors, capacitors, and diodes are blackened or charred.
Under normal circumstances, even if a resistor is burnt, its resistance value will not change, its performance will not be altered, and it will not affect normal use. In this case, a multimeter is needed to assist in the measurement.
However, if capacitors or diodes are burnt out, their performance will change, and they will not be able to play their proper role in the circuit, which will affect the normal operation of the entire circuit. In this case, new components must be replaced.
Step 3: Inspect the integrated circuits on the circuit board, such as the 74 series, CPU, coprocessor, AD converter, etc., for any bulging, cracks, burning, or blackening. If any of these are found, it can be basically determined that the chip has been burned out and must be replaced.
Step 4: Observe the traces on the circuit board for peeling, burning, or open circuits. Check if the copper vias have detached from the pads.
Step 5: Observe the fuses on the circuit board (including fuses and thermistors) to see if the fuses are blown. Sometimes, because the fuses are too thin to see clearly, you can use an auxiliary tool such as a multimeter to determine if the fuse is damaged.
The above four situations mostly occur due to excessive current in the circuit. However, the specific cause of the excessive current requires specific analysis of each case.
However, the general approach to finding the problem is to first carefully analyze the circuit board's schematic diagram, then find its upstream circuit based on the circuit where the burned-out component is located, deduce upwards step by step, and analyze the places where problems are most likely to occur based on some experience accumulated in the work, and find out the cause of the fault.
"Why are you still watching? Get your hands dirty and start doing it once you're full."
Saint Karina stroked Esther's fluffy little head like she would pet a puppy.
She swallowed it all over her face and neck, and even the strands of hair at her temples had a glue-like liquid in them.
Esther drank too eagerly, and the spring water gushed out more and more under the serpent's teasing. Some of the water that she didn't swallow in time would leak from the corners of her mouth.
"Suck it-"
It was the sound of the little snake licking her lips. Her stomach was already full of delicious food, but her taste buds were still not satisfied.
She was still restless, but she knew she couldn't drink anymore.
If she were to drink it, she would have to save it for next time. If she drank it again, her stomach would probably burst open from being filled with the life energy contained in this vast fountain of life.
Now, she has to get to work and get hands-on experience.
For most circuit boards, the aforementioned observation method cannot reveal the problem. Only a small number of circuit boards will undergo physical deformation due to special reasons, making it easy to identify the cause of the fault. For most faulty circuit boards, it is still necessary to use a multimeter to systematically measure the main components and key points on the circuit board to find and solve the problem.
Before measurement, it's essential to determine whether the circuit primarily uses analog or digital signals. For circuit boards with a schematic diagram, this can be determined by referring to the diagram. However, for circuit boards without a schematic diagram, the following two methods are generally used to determine this:
① Observe the components on the circuit board to see if there is a microprocessor on the circuit board. Whether it is the early 80 or 51 series or the widely used DSP now, as long as such a chip appears on the circuit board, it means that there is a bus structure on the board and digital signals will occupy a large part. It can be treated as a digital board.
② For circuit boards without microprocessors, observe the components on the board to see how many chips use 5V power. If there are many 5V power chips, it can be treated as a digital circuit for repair. The repair methods for digital circuits and analog circuits are different. Generally speaking, analog circuits are simpler to repair, and you can deduce the problem step by step.
However, in digital circuits, the circuits are all connected to a bus, and there is no clear hierarchical relationship. Therefore, they are more difficult to repair.
The following focuses on the static measurement method for digital circuits. Repairing them mainly follows these steps:
Step 1: Use a multimeter to check for a short circuit between the power supply and ground.
The method of inspection is as follows: Find a chip powered by a 5V power supply and measure two points on the diagonal (for example, for a 14-pin chip, measure pin 7 and pin 14; for a 16-pin chip, measure pin 8 and pin 16).
If there is no short circuit between the two points, the power supply is generally working normally. If a short circuit occurs, the cause needs to be found through troubleshooting.
These steps are just the basic approach to power supply repair. For particularly complex circuit boards, specific problems require specific analysis. The power supply is the foundation of the circuit; only when the power supply functions properly can subsequent circuit applications be discussed. Therefore, power supply measurement is crucial, yet it's also a step that repairers often overlook.
Step 2: Use a multimeter to measure the diode and observe whether it is working properly.
Under normal circumstances, when measuring the negative terminal in resistance mode, the reading for forward inversion is tens to hundreds of ohms, and for reverse inversion, it is thousands to several thousand ohms. Generally speaking, diode damage occurs because excessive current in the circuit causes the diode to break down.
Step 3: Use a multimeter in resistance mode to measure the capacitor to check for short circuits or open circuits. If any are found, it indicates a problem with that part of the circuit. The next step is to determine whether the problem lies with the component itself or the circuit connected to it. This can be done by desoldering the suspected component and checking for open circuits. This will help pinpoint the problem.
Step 4: Similarly, use a multimeter to measure the integrated circuits, transistors, resistors, etc. on the circuit board to see if they meet their logic performance.
If the circuit board includes a bus structure, there will generally be pull-up resistor arrays on the bus. Measuring the resistor arrays is a very important step, as their quality can provide a preliminary indication of the condition of the chips connected to the bus.
After inspection using observation and static measurement methods, most problems encountered in circuit board repair can be resolved. It is important to ensure that the power supply is normal to avoid causing secondary damage to the circuit board in the next step.
"It's fixed, Sister Saint Karina!"
Thanks to the hard work of the craftsman, the circuit board that Saint Karina had assigned to Esther was finally repaired.
She put in a lot of effort; her hands were soaked until the skin turned white, a testament to working too long in an extremely humid environment.
She raised her head, looking at the scenery that seemed both far away and close at hand: the waterfall cascading down and the seven-colored rainbow that appeared after the water flowed through it. A sweet smile appeared on her face, a smile that also held a touch of infatuation.
She was very proud of her craftsmanship, and even though Santa Karina was convulsing, she used her head as a support and didn't care that the water was wetting the floor.
"Hmm...you really are amazing, Esther."
Saint Karina would never hesitate to praise her obedient, well-behaved, and hardworking younger sister.
Her complexion was rosy, a sign that she had been nourished after the release.
To be honest, it feels really good to see my previously arrogant and despicable younger sister, who used to threaten and intimidate me with despicable means, turn back into the obedient, sensible, and self-respecting sister who would do anything without complaint.
As long as she doesn't act like a weakling, Saint Karina wouldn't mind having more of these good things, like getting close to pretty girls.
"Sister Saint Karina, would you like to do this a few more times?"
She has completely given up thinking; everything she does is done according to her heart and for the sake of happiness.
She just wanted to replenish her life force, that's all...
She felt it was a waste to see the water flowing down from the waterfall, so she cupped some in her hands, buried her head in it, and drank it all down as if it were nectar.
Not satisfied after finishing its drink, it stretched out its tiny pink snake and licked up every last drop of water from its palm, not wanting to waste a single drop.
She was ostensibly asking Saint Karina, but what she really wanted was what she wanted herself.
"I'm very comfortable now, I'm in my comfort zone~"
Saint Karina grinned mischievously and deliberately refused first.
She was playing hard to get, and sure enough, a look of disappointment quickly appeared on Esther's face.
If she had orc ears, you could see the orc ears change from standing upright to drooping down, and the tail, which used to wag wildly from side to side to fawn over her, would change from a fluffy big tail hanging listlessly, looking like she had lost hope and had no will to live.
"However, if you can rouse my holy sword, you can fire again, or even more times, until you're exhausted. I'll allow you to treat me however you like~"
Saint Karina pulled out her beautiful holy sword, looking like she was trying to fool a child.
Her holy sword was one with her heart; the sword was like a miniature Saint Karina, or even Saint Karina's avatar. The tails of demons, dragons, and orcs, if touched inappropriately, would send back intense sensations to their master. The same was true of the holy sword.
"How about it? Swear allegiance to my holy sword."
She placed the Holy Sword, as a manifestation of joy, into the appropriate slot. Saint Karina placed Esther's hand on it, but Esther only loosely grasped it, a hint of struggle flashing in her eyes.
However, the evil power soon regained control; it was the power that Saint Karina had implanted in Esther's heart, filling the void within her.
Then, the struggling look in his eyes immediately returned to calm, as if nothing had ever happened.
She regained her sweet smile, the one Saint Karina loved most, and became compliant and obedient, doing whatever Saint Karina asked.
“Okay~ Sister Saint Karina, you know I wouldn’t refuse you…”
All her ulterior motives vanished. What remained in her heart was her primal longing.
She did all of this because of that huge, empty void in her heart.
Saint Karina had contaminated that hole with special means, and Esther could only find the satisfaction of having her emptiness filled by Saint Karina. It was like a dependency relationship, to the point that fish couldn't live without water, and Saint Karina was the living water that Esther craved.
"Hmm..."
She groaned and bit her tongue, drawing blood.
Then, she lowered her head and brought it close to Saint Karina's holy sword, her cherry lips about to kiss it.
The bloody kiss, some of it spilling from the corners of her mouth, combined with Esther's infatuated expression, made her look incredibly alluring.
"Um..."
Saint Karina also groaned; the damp sensation of the holy sword, nourished by her blood, almost numbed her brain.
Her limbs and bones were trembling, and an electric current ran through her spine, almost striking the top of her head.
From this moment on, the master-servant relationship between the two completely changed. And this change is irreversible.
“Estelle, let me teach you. How to maintain a holy sword… well, it’s different from how you maintain an ordinary sword.”
First, a sword is mainly composed of three parts: the blade, the scabbard, and accessories. Most swords are made of materials such as iron, steel, copper, and wood. They should not be stored in damp places, and should not come into contact with acidic or alkaline substances, so as to prevent the sword from rusting.
During use, avoid touching the sword blade with your hands as much as possible to prevent sweat stains from corroding the surface.
Then, the sword maintenance steps:
1. Cleaning the sword: Use a pure cotton cloth, flannel, or deerskin to gently wipe away any residual oil and dust from the sword. Then, apply a small amount of sword polishing oil evenly to the sword with cotton gauze. After three minutes, rub the sword vigorously back and forth with the cotton gauze for about 2-3 quarters of an hour until the sword becomes warm. The purpose of this is to remove impurities from the blade surface and to promote a chemical change in the phosphorus and calcium, which will naturally magnetize and fill the pores on the sword.
At this time, you must concentrate to avoid being cut or punctured.
2. Polishing the sword: Place a long towel on the table, lay the sword flat on it, and use a cloth or a small wooden block about 1.3-12 cm long to rub the blade back and forth with the flat side until it gets slightly warm.
When the blade appears oily but isn't quite, apply a small amount of polishing powder and continue polishing for about fifteen minutes. This removes scratches and increases the rate at which the pores on the blade shrink. All of these actions require a calm and peaceful mind, making it an excellent way to cultivate one's character.
3. Apply rust-preventive oil: If you don't maintain the sword daily or live in a humid environment, you must apply a thin layer of rust-preventive oil before sheathing the sword. Gun oil, sewing machine oil, or other rust-preventive oils are all acceptable to prevent contact with air. However, if you maintain the sword regularly every day, keeping the blade clean and shiny will actually benefit the sword's development, and you won't need to apply oil.
4. Maintenance of parts: Simply wipe the parts with the original maintenance cloth or leather. If you want the copper to be shiny, you can hold the cloth in a loop and rotate it left and right. Since there is already some oil on the cloth, it will have a protective effect and prevent oxidation from producing copper rust.
5. Nourishing the scabbard: The final step in nourishing the sword is to hold the scabbard with the original maintenance cloth or leather band and rub the sword vigorously up, down, left, and right to generate heat in the wood. In this way, the oil inside the wood will slowly rise to the surface.
Over time, the entire scabbard will be covered with a layer of wood oil, like a layer of glossy wax. Not only does it have an excellent texture, but it also only needs a little wiping to keep it shiny forever.
"I understand, Sister Saint Karina..."
Esther was very eager to learn; as long as Saint Karina explained the basics of sword maintenance, she could immediately apply them to other situations.
"I greatly appreciate your knowledge, but this holy sword is a precious weapon; it must be handled with even greater care..."
Her little serpent had wrapped around the tip of the holy sword, so she certainly understood just how powerful this treasured sword was.
Moreover, like the indescribable places, this place also produces some delicious liquids.
However, its color is different from the viscous, glue-like water; it is a milky white, sweet-smelling liquid similar to milk.
"Any item requires careful maintenance to be preserved for a long time. Swords and knives are no exception; they are not immune to rust and decay. However, some have survived for over a thousand years. Whether something becomes a 'family heirloom' depends entirely on how it is cared for. Let's discuss and research it together!"
So Esther prepared the tools for nurturing the sword.
Sword oil: Wipe the sword blade to prevent rust.
Talc: Removes dirt and absorbs excess grease.
Soft cotton cloth: Wipe the blade, remove dirt, and apply oil evenly.
Tablecloth: to prevent damage to tables, chairs, and furniture, and to prevent your beloved knives and utensils from getting scratched.
Gloves are not necessary: they can keep out dirt, prevent scratches, and avoid hand sweat corroding the metal of knives and swords.
Plastic wrap: isolates dust and air.
