Chapter 345
Seeing that Su Chen didn't say anything, Sun Simiao turned and walked towards his room.
After a while, Su Chen finally remembered that he found pyrite when he went to Hua County that time and brought some back.
Those square pieces were very small, and Su Chen didn't plan to have anyone bring them back because he thought it was troublesome.
He only brought back some large pieces of pyrite with irregular shapes.
"What the hell, why call it pyrite? Can't you just show it as sulfur?"
"Old immortal, you have been... um? Where are you?"
Su Chen came to his senses and found that Sun Simiao was gone.
"My friend, I have four or five taels of sulfur left here. If you need it, take it.
Remember, this thing is corrosive and long-term contact with the skin is harmful to the human body." Sun Simiao handed a jar to Su Chen and reminded him carefully.
"Okay, old immortal, I have more than 30 kilograms of sulfur ore.
Teach me how to refine it some other day. I'll take these and try them first. Goodbye!"
Su Chen has been busy recently and forgot to take the pyrite to Sun Simiao for identification.
Su Chen took the jar of sulfur and left quickly.
...
After returning to the living room, Wang Xi was the only one in the living room.
"Wang Xi, go find some charcoal and grind it into powder. Put it in a pottery jar and bring it to the backyard. About two kilograms will be enough. Find a scale by the way."
After saying that, Su Chen immediately walked to the warehouse where the saltpeter was stored.
When he arrived at the warehouse, Su Chen picked up a large glass bowl and scooped up a large bowl of saltpeter.
"Make two kilograms of explosives for fun first. Saltpeter has the highest proportion."
Su Chen mixed the amounts of the three materials according to the calculation of one kilogram and ten taels.
Two kilograms of explosives require fifteen taels of saltpeter, three taels of sulfur, and two taels of charcoal.
Just now, I asked Wang Xi to prepare two kilograms of charcoal powder in the living room, just to ask him to prepare a suitable pottery jar.
When leaving the warehouse, Su Chen grabbed a handful of cotton.
Su Chen came to the backyard alone, feeling a little excited.
"Damn, this is my first time to do this, and I haven't seen any videos about it before."
Because it was his first time to make gunpowder, Su Chen planned to do it in the backyard in order to avoid the annihilation of the Tang Dynasty royal family.
A few minutes later, Wang Xi came to the backyard with a jar in his left hand and a scale in his right hand.
"My Lord, please see if it is suitable!" Wang Xi gave the ground charcoal powder to Su Chen for inspection.
"This is fine, go and mix some mud. It will be used to seal the jar mouth later, don't make it too thin."
Su Chen instructed again.
When Wang Xi turned to leave, Su Chen continued: "Find another bamboo with the thickness of a finger, it must be hollow."
"Here!" Wang Xi turned and left.
"Wait, wait, how do you recognize this scale?" Su Chen suddenly found that this scale was different from the ones in later generations.
Wang Xi immediately stepped forward and carefully taught Su Chen how to read the scale.
After two minutes, Su Chen finally understood the scale.
There was no jin on the scale bar, only liang, qian, and fen, and the maximum weight could be weighed was five jin.
If you want to weigh more than five jin, you need to change the scale.
After teaching Su Chen to read the scale, Wang Xi went outside to mix mud.
After Wang Xi left, Su Chen found that there was no table in the backyard, and there was nothing to pad the bottom, so it was not easy to mix and stir.
Putting down everything, Su Chen went to the study to get some paper and moved a chair from the living room.
Li Shimin saw Su Chen hurried to the study and left in a hurry.
Without saying a word, Li Chengqian wanted to follow and was stopped by Su Chen.
He only said one sentence: Wait here!
After all the preparations were done, Su Chen began to weigh the charcoal powder.
Weigh two taels of charcoal, pour it on a piece of paper, and then weigh out fifteen taels of saltpeter.
Finally weigh out three taels of sulfur.
"This scale works well! The standard formula is: 75% saltpeter, 15% sulfur, 10% charcoal. I hope the book is not a lie."
Su Chen had just weighed the three raw materials when Wang Xi brought over the two things he had prepared.
"Wang Xi, go to the living room! Find Zhang Long, Zhao Hu and the other four." Su Chen thought about it and decided to send Wang Xi away.
It would be too unfair if he was silenced by Li Shimin.
After Wang Xi left, Su Chen carefully stirred the prepared gunpowder evenly.
"Hmm? What will happen if the charcoal in this pottery jar is left inside? I remember that firecrackers are filled with a lot of yellow mud.
Pour it out, otherwise it won't hold two pounds of gunpowder."
Fill the gunpowder carefully and tightly.
Then, Su Chen began to twist the cotton into a loose thread, about one meter long.
He also twisted a thread about one foot long to estimate the ignition speed.
Otherwise, if the calculation is wrong, it will be too late to escape after the ignition, and that will be a lot of fun.
Press a piece of paper on the gunpowder in the can, and thread the cotton money into the hollow bamboo, piercing it.Insert the white paper into the gunpowder.
After doing this, Su Chen carefully recalled each step.
After confirming that everything was correct, seal the pottery jar with mud.
Hollow bamboo protects the cotton thread, so the cotton thread will not be unable to burn due to the moisture in the mud.
After the mud was applied to seal the mouth, Su Chen washed his hands and put away the remaining sulfur.
Almost two times of two kilograms of explosives can be made.
There was less than two taels of saltpeter left, so it was directly washed away with water, and the charcoal was ignored.
Su Chen walked towards the living room with the "explosive" jar.
...
In the study, Li Shimin had been waiting for more than 20 minutes since Su Chen left.
The three people frowned, not knowing what Su Chen was fiddling with.
Wei Zheng was playing with the telescope on the desk and shone it at Li Shimin.
It doesn't matter if he doesn't shoot. Wei Zheng looked at Li Shimin's face with the telescope at such a close distance, as if he was sticking it on the emperor's face.
He was so scared that he almost threw the telescope away.
"Great, has Su Chen ever mentioned the use of sulfur?"
Li Shimin was really getting impatient waiting, having waited for Empress Changsun for more than two hours.
Now he was waiting again.
"He never mentioned it, but my brother-in-law was very excited when he talked about the yellow stone." Li Chengqian shook his head and recalled slowly.
"After talking about the yellow stone, he asked me which country could be destroyed with the current strength of the Tang Dynasty."
Li Chengqian described the situation one by one.
"Oh? Is there any connection between the two?" Li Shimin tapped the desk with his fingers rhythmically.
"Sulfur is generally only used for alchemy, and at most can only be used to make rockets. Does Su Chen want to attack Shuofang with fire?" Fang Xuanling followed up with analysis.
Li Shimin shook his head and waved his hands, saying, "It is impossible. Although Shuofang is small, the capital city wall is eight feet high and is a city that is easy to defend but difficult to attack. How can it be attacked with fire?"
Fang Xuanling thought about it and nodded.
"This bastard boy is making me anxious to death." Li Shimin slapped the desk and cursed.
While Li Shimin and the others were guessing in the study, Su Chen had returned to the living room.
"Su Chen, what are you doing with a pottery jar?"
After the four people including Empress Changsun finished bathing, they sat in the living room and wiped their hair.
"Uh, mother, you guys rest here, His Majesty and I have something to do." Su Chen stopped and made an excuse, then continued to walk towards the study with the explosives.
"Well, you guys go and get busy!" Empress Changsun said casually.
Su Chen came to the door of the study, "Your Majesty, follow me!"
Without waiting for everyone to speak, Su Chen turned around and left. Regardless of whether the explosives were successfully detonated or not, it was not suitable to be tested in the manor.
Su Chen planned to go to the barren mountain outside the manor to detonate the explosives.
