When Wu Chengsi brought out the packed gunpowder bag, Han Cheng couldn't help but ask, wondering if Wei Heng was really telling the truth and that the father-in-law was really boiling the medicine?
You can't blame him for thinking so. The appearance of this gunpowder bag is very similar to the gunpowder bag sold in pharmacies, but it is much larger and has a long fuse.
Wu Chengsi handed him the gunpowder bag and said, "Take it first." He turned to his guards and asked them to find an open space in the camp.
After arriving at the clearing, Wu Chengsi looked around and suddenly saw a big rock. He asked Han Cheng to place the gunpowder bag next to the big rock and said with a smile: "Okay, we can start testing violence."
Although the fuse was extremely long and there was almost no danger, Wu Chengsi still handed over the glorious mission of point fuse to Han Cheng and hid himself more than ten feet away from the gunpowder package.
He also asked his personal guards to guard the four directions of the open space to prevent anyone from accidentally entering the detonation point.
"Han Cheng, it's okay, run over and hide immediately after lighting it, don't hesitate at all!" Wu Chengsi, who was lying on the ground, shouted from a distance.
Han Cheng originally didn't think he was doing something dangerous, but when he saw Wu Chengsi's behavior, he still had a sudden thought in his heart, thinking: "Could this medicine bag release poisonous gas when lit?"
He did not dare to be careless. After lighting the fuse, he quickly jumped to Wu Chengsi's side and lay down carefully.
After a long while, he looked up and found that nothing had happened. Just when he was wondering if the fuse had gone out, suddenly, there was a thunderous roar in his ears——
…
In a tent not far from the commander's tent, Pei Xingjian was checking the intelligence. Before Wu Chengsi joined him, he sent a large number of Korean soldiers to sneak into Yalu City to find out the intelligence in the city.
News would continue to come out from the city every day, but unfortunately there was no more useful information, so he never reported it to Wu Chengsi.
At this moment, a roar that shook the earth and the mountains reached his ears. This sound was slightly different from thunder. Pei Xingjian had never heard it before.
He immediately left the camp and asked the soldiers outside the door: "What happened?"
The soldier looked in a certain direction and said in a daze: "That's where the sound came from. I saw a bunch of... black clouds rising from the ground."
Black cloud?
Pei Xingjian thought: "The occurrence of such a major event in the camp must be related to Wu Chengsi. Considering the methods of siege and the divine fire team he mentioned a few days ago, could this be the movement caused by him?"
He stepped towards the direction pointed by the soldier. After taking just a few steps, he saw Han Cheng running towards him, with an expression on his face that was half frightened and half excited.
"General Han Lang, what was the sound just now?" Pei Xingjian asked urgently.
"It's gunpowder, the sound of gunpowder exploding!" Han Cheng replied, adding: "That's what the general said."
"Gunpowder?" Pei Xingjian was stunned.
"Anyway, it is different from other medicines. When ignited, it can make a loud noise like thunder, and... it also has very terrible destructive power!" Han Cheng explained with difficulty.
Pei Xingjian pondered for a while and said, "Listen to what you said, this is the siege weapon that the general mentioned before?"
"Yes, yes!" Han Cheng nodded repeatedly. After the test, he went to check it out. After the roar, the gunpowder package disappeared, a pit appeared on the ground, and the stones next to it became broken.
These signs all indicate that this medicine can be used in siege. This is the method of siege mentioned by my father-in-law!
When the two came to the open space, several other generals arrived, but Wu Chengsi was nowhere to be seen. Han Cheng explained: "My father-in-law has gone to make that kind of gunpowder again. Let's wait a moment."
"Gunpowder? What gunpowder?" Hei Te Changzhi opened his mouth and asked.
Han Cheng had no choice but to waste his time and repeated what he told Pei Xingjian.
All the generals looked at each other, Russell touched his chin and said: "I heard that Mrs. Guo opened a medical clinic and must be proficient in pharmacology. Perhaps the method of brewing gunpowder was told to the general by Mrs. Guo!"
Wu Youji crossed his arms and frowned: "That shouldn't be the case. I've been in Chang'an for so many years, but why haven't I heard of such a thing as gunpowder?"
Pei Xingjian pondered: "I have seen this word in an ancient book. It seems to be a medicine accidentally made by alchemists. Because it can catch fire, it is called gunpowder."
Han Cheng nodded repeatedly: "Yes, I did see flames coming out, it must be this thing!"
Everyone was relieved to hear that this thing had an origin.
Pei Xingjian frowned. The gunpowder in the ancient book only said it could catch fire, but it didn't say it could make such a loud noise.
Not long after the generals waited, Wu Chengsi finally came over, holding a large medical bag in his hand.
After seeing the gunpowder bag, Han Cheng's eyes became more fearful. He stepped forward to take the gunpowder bag and said, "Master, I'll take it."
Wu Chengsi smiled and said: "Yes, I am very safety-conscious. Although this thing is powerful, it must be used with care and there must be no sparks. You all remember from now on that wherever gunpowder is, it cannot be seen within a hundred steps."
A spark!"
Han Cheng nodded and took note. He had seen the power of this gunpowder with his own eyes, how could he dare to be careless in the slightest.
Hei Te Changzhi stared at the medicine bag for a while, scratched his cheek, and thought to himself: "It's really strange, this medicine bag can also be used to attack a city?"
Pei Xingjian's eyes flashed and he said eagerly: "General, please try it immediately. I want to see it with my own eyes."
Wu Chengsi smiled and said: "Don't worry, everyone must sign a confidentiality agreement before testing violence."
"Confidentiality regulations?" Wu Youji blinked.
"Yes, from now on, this gunpowder will be the biggest killer weapon of our Zuo Wu Army. This kind of thing requires the highest level of confidentiality. Everyone who participated in the test today must not reveal the existence and power of gunpowder to the outside world, otherwise they will
The strictest punishment will be imposed, do you understand?"
All the generals said in unison: "The last general takes orders."
"It's a very important matter. I'm afraid you won't remember it deeply if I just give it verbally, so everyone must sign the confidentiality agreement so that you can keep it in your mind. Whoever violates the order in the future will be severely punished by military law in the agreement!"
After saying that, he ordered the guards to get paper and pen, write down a confidentiality regulation similar to a military order, and then ask everyone to sign on it, and those who can't write should fingerprint it.
After the generals and guards signed the signatures, Wu Chengsi began the second test of violence. This time, no more stones were placed next to it, just to let everyone see the power.
Black Teeth Changzhi was very disapproving at first, but when he saw Han Cheng's caution when lighting the fire, and how quickly he ran over after lighting the fire, he thought to himself: "Han Cheng is always very courageous, why are he so scared?"
With a pair of big black and white eyes open, he stared closely at the gunpowder bag.
At this moment, there was a loud boom. Because the distance was closer, the sound that exploded in his ears this time was several times more violent than the one he heard just now.
I saw a flash of fire, a black cloud rising slowly, and a few small gravels flying from a distance, hitting him in the face.
In the center of the gunpowder bag, countless gravel and soil fell like raindrops.
Pei Xingjian said anxiously: "General, can we go over now?"
This was the first time Wu Chengsi saw him lose his temper like this. As soon as he agreed, Pei Xingjian ran to the gunpowder bag faster than Han Cheng had just run back.
Looking at the two-foot-deep depression in the ground, his eyes were as bright as stars.
Hou Yanjing, Wu Youji and other generals also ran towards him. Wu Youji turned around and shouted:
"Second brother, how can gunpowder be so powerful? Those alchemists are really annoying. They don't report such things to the court!"
Wu Chengsi slowly approached and said with a smile:
"This is a new type of gunpowder. My wife accidentally prepared it. She accidentally knocked over the candlestick and ignited it. At that time, the amount of gunpowder was still very small, but it was already very powerful. After she told me, I immediately
I realized that this thing could be used in the military."
"Second sister-in-law is truly a good helper to second brother!" Wu Youji said happily.
Pei Xingjian thought for a moment and asked, "General, how difficult is it to obtain the materials to configure this kind of gunpowder?"
Wu Chengsi secretly praised and said sternly: "Although the required materials cannot be said to be off the street, they are still relatively easy to obtain."
Materials need to be transported, and sooner or later they cannot be concealed, but the most important thing is the formula. Without the best formula, gunpowder will not be able to exert its power.
Pei Xingjian added: "General, I think this new type... gunpowder is an important discovery. We can report it to the court and ask the court to set up a special institution to study the uses of gunpowder!"
Wu Chengsi smiled and said: "General Pei's suggestion is very good, but if we want the court to pay attention to this thing, we first need to use it to shine on the battlefield!"
Russell rolled his eyes and said: "General, I have an idea. We can use a catapult to throw this thing into the enemy's city and scare those Goryeo grandsons to death!"
Hei Te Changzhi loved to argue with him, and curled his lips and said: "What's the use of throwing it in? It won't kill many people. In my opinion, we should put this thing outside the city gate and break open the city gate!"
"General, what do you think?"
Pei Xingjian looked at Wu Chengsi. Wu Chengsi was the first to discover this thing. He believed that the other party had already thought about how to use it.
Wu Chengsi said with stern eyes: "Blowing up the city gates is too boring. If we want to blow up the city walls, we will blow up the walls. I want this siege to become a milestone in the history of our Tang Army's wars!"
