The nights in Tokyo are always sleepless, and even in the latter half of the night, Wazi's shops have no intention of playing foreign games. Qinbei Pavilion
It wasn't until the sky got brighter that Shi Qian and Ling Zhen came back. Ling Zhen was still carrying a huge burden.
"Why have you been gone so long?"
Sun Lei asked doubtfully. It had been almost two hours since he left.
"Brother, those officers and soldiers searched Brother Ling Zhen's residence for a long time, and that's why they wasted time."
Shi Qian explained.
"My little brother didn't expect it to be so big this time."
Ling Zhen had a wry smile on his face. He originally thought that he would be fine with a military stick for a while, but now it seems that this time the trouble has been a bit big, so he may not be spared so easily.
"Brother, I have brought all these things. Let's try it now?"
Ling Zhen was not too worried, and soon his mind turned to the formula of gunpowder.
"Here? You still think there wasn't enough movement last night? It's almost dawn, are you going to trigger a manhunt across the city?"
Sun Lei was a little speechless. Ling Zhen was really a research madman. He was probably at the stage of obsession.
"Forehead……"
Ling Zhen scratched the back of his head in embarrassment, and then realized that Tokyo was not a place to test gunpowder.
"Let's wait until daybreak and find a secluded place outside the city."
Sun Lei looked at the pale Dongfang and said.
At this time, Wazi had almost left the country. Sun Lei and the others found a breakfast shop and sat there for a while, then followed the crowds out of the city to the outside of Tokyo.
The crime Ling Zhen committed was only inside Jia Zhanku. The guards at the city gate knew nothing about it and did not question him too much. Instead, they let him go because Ling Zhen was the deputy gunner of Jia Zhanku.
"Brother, this place is good."
Ling Zhen led everyone to a remote forest outside the city. There was wasteland for more than ten miles nearby, and he was not afraid of any big noise.
"Should I do it alone or together?"
Sun Lei looked at Ling Zhen and said.
"Then let's compete together!"
Ling Zhen said with great confidence. He placed the baggage he was carrying on a huge stone and opened it. He and Sun Lei stood across the stone.
"Azhen, stop it, you can't win!"
Sun Lei suddenly laughed when he saw the scene. Isn't this the scene of fighting with Azu?
"The winner is still undecided!"
Ling Zhen looked at Sun Lei and said, he thought about it for a long time and perfected his formula countless times in his mind. He didn't believe that his gunpowder was not as powerful as Sun Lei.
"Then come on!"
Sun Lei smiled, he had never learned elementary chemistry, how could he not be as good as an ancient man from a thousand years ago?
Ling Zhen quickly opened a bunch of bottles and cans, which contained powders of various colors and some fragrances. Ling Zhen even prepared two small round furnaces similar to alchemy furnaces.
"What are these? Are you cooking? Why is there still oil?"
Sun Lei looked at the bottles and jars with confusion.
"Brother, you don't understand these? This is clear oil, this is tung oil, this is thick oil..."
When Ling Zhen saw that Sun Lei didn't understand anything, he instantly felt proud. It seemed that he would definitely win this competition.
"What formula is this? Yellow dynamite? Nitroglycerin?"
Sun Lei looked at Ling Zhen in shock. There was no oil in the black powder formula, and he didn't even know what the oil was. Only yellow gunpowder uses nitroglycerine, but that stuff is difficult to prepare and extremely unstable, which is obviously not the case with these.
"Brother, you don't even know the formula for gunpowder, do you?"
Ling Zhen looked at Sun Lei with some disappointment.
"Maybe the formula is different."
Sun Lei smiled.
"Brother, there is a record in the "Gunpowder Method" in "General Martial Arts": Jinzhou sulfur fourteen taels, wohuang (sulfur) seven taels, two and a half kilograms of flame salt, one tael of maru, one tael of dry paint, one tael of arsenic. Two, one liang of fixed powder, one liang of bamboo, one liang of yellow elixir, half a liang of yellow wax, one liang of clear oil, half a liang of tung oil, fourteen liang of rosin, and one liang of thick oil.”
Ling Zhen saw that Sun Lei didn't understand anything, so he pointed at the materials and introduced them one by one.
"I know, let's start competing!"
It was enough for Sun Lei to recognize the three items: sulfur, saltpeter, and charcoal. As for the others, Sun Lei didn't even look at them.
The best recipe for black powder is 10% sulfur, 15% charcoal, and 75% saltpeter. The so-called "mononitrate, disulfide, and charcoal" formula among the people is seriously wrong. There was obviously too little saltpeter and too much charcoal. The biggest feature of this kind of folk black gunpowder is that it can be stored for a long time, so the firecrackers can still explode after being stored for two or three years. However, if there is too much stabilizer such as charcoal, the power will be greatly reduced.
And the formula in the "Martial Arts General Essentials" mentioned by Ling Zhen also adds a lot of messy things, and even adds more than a dozen ounces of rosin. How powerful can this be? All burning rosin and sulfur? Thank God if it doesn't misfire like this.
"Brother, do you really know?"
Ling Zhen didn't believe it, but Sun Lei looked calm and composed. If the victory was certain, he didn't understand how a person who couldn't even recognize all the materials could be so sure?
"I know, I know!"
Sun Lei took an alchemy furnace and looked at it with a smile. It was his first time to do chemical experiments with this thing. It was novel enough, but this small alchemy furnace was similar to the crucible.
"Really know?"
Ling Zhen's face was full of disbelief.
"How about I give you a stick of incense?"
Sun Lei nodded and smiled. He knew that Ling Zhen didn't believe him, but these are not important. We will find out when the thing is finished.
"No, let's get started!"
Ling Zhen couldn't bear such words, and immediately said with a serious face.
The two of them each took a small alchemy furnace and began to add powder to it. Ling Zhen was eager to win and was concentrating on it. He added every ounce of powder very carefully, for fear of losing the weight.
Sun Lei was different. He held the small jar containing sulfur, saltpeter, and charcoal and frowned. The quality of these materials was mixed, even worse than he thought.
"It's not pure enough, and I don't know how much power it can exert!"
Sun Lei shook his head helplessly and said, the purity of sulfur and wohuang was average, the purity of flame salt was even worse, and the bamboo root was not even burned into charcoal.
"Just make do."
Seeing the materials like this, Sun Lei could only shake his head and start. After all, Ling Zhen could use these things and a recipe with serious errors to make explosive gunpowder, so he should be able to make it too.
The two of them started refining the elixir in a small furnace. Sun Lei first simply purified the materials, and then mixed the three materials in the correct proportion. Since he didn't have time to pound them slowly, Sun Lei directly added a small amount of water to help the powder and mixed it thoroughly. Just pound them together, and finally let the gunpowder dry in the alchemy furnace over low heat.
On the other side, Ling Zhen was indeed covered in sweat with a solemn face as he kept pounding the ingredients and adding them to the small alchemy furnace.
When Sun Lei's gunpowder was ready, Ling Zhen was still adding powder to the alchemy furnace.
"Brother, is it done?"
Ling Zhen suddenly raised his head and looked at Sun Lei, who was smiling across his face. At this time, Sun Lei was holding a paper bag and looking at him with a smile. It was obvious that the gunpowder had been prepared.
"Of course, take your time, don't be in a hurry!"
Sun Lei said with a smile.
"How can it be?"
Ling Zhen couldn't believe it. He looked at the pile of jars in front of Sun Lei. Most of the materials were untouched. What kind of gunpowder was this made of?
