Zhao Huan, Liu Ying and others gathered around Liu Chang.
Liu Chang had people grind the stone liquid yellow and saltpeter into powder and put them in two sand jars respectively.
He also had a pit dug, placed the cauldron in the pit, and filled it with soil on all sides.
"Brother, please stay away... This is my first time doing something, and I don't know if I can succeed..."
Liu Chang said to Liu Ying carelessly.
"What will happen if it fails?"
"Brother, do you still remember the ore bursting just now?"
"certainly..."
"This iron pot may burst and injure everyone... This thing is so powerful that even a strong bow or crossbow cannot reach it..."
"No!"
When Liu Ying heard this, not only did she not retreat, but she took a few steps to Liu Chang's side and pulled him over, "It's so dangerous, don't try it!"
Liu Chang suddenly became anxious, "Second brother, if this thing is made, the mining efficiency can be increased a hundred times! The big man will no longer be short of iron, not to mention, this thing can also be used on the battlefield, oh, second brother, you
If you don’t understand, just go over there and watch!”
"Then I will stand here and watch you take care of it."
"No, what are you messing around with here?! You can't help!"
Liu Ying didn't speak, just stood aside and looked at him silently.
Liu Chang was about to speak, but he found that Luan Bu had also walked up and stood on the other side. Zhao Huan was stunned, cursing in his heart, and walked to them helplessly. Liu Chang turned around and started to curse.
In operation, he lit a few soap locusts and threw them into the pot. Then, he lit up the fireworks with Shiliuhuang and saltpeter. Liu Chang kept waiting until he could no longer burn the fireworks, and hurriedly took out the charcoal to stir-fry.
, the flames were steaming, and Liu Chang was sweating all over.
Just stir-fry until one-third of the carbon is gone, Liu Chang anneals immediately, takes out the mixture before it cools down, and lowers the heat.
"ah!"
Liu Chang looked at the mixture and exclaimed. At that moment, Liu Ying suddenly stretched out her hand, picked up Liu Chang and threw him backwards. He moved quickly and without any sloppiness. After throwing out Liu Chang, he held his head.
, waiting for unknown dangers.
"boom...."
Liu Ying did not encounter any danger, but Liu Chang did.
Liu Chang fell heavily to the ground, clutching his waist in pain, "Even if I fail this first time, you can't throw me like this... Oops, my waist, my back..."
Liu Ying rushed to Liu Chang's side and helped him up.
"Are you okay? I thought... something was wrong..."
"There was nothing wrong with me before you threw me..."
Seeing that Liu Ying was about to burst into tears, Liu Chang jumped up and patted the dirt on his body, "It means that I have a strong body. I have been beaten so many times over the years, but nothing happened. This is definitely not true."
Ordinary people can do it!”
Liu Ying breathed a sigh of relief and could still brag. It seemed that there was no problem.
Liu Chang helplessly looked at the gray-white particles he took out, shaking his head, "This is not right at all... Is there too much carbon? Or is it not broken enough?"
"Try again..."
Facts have proved that just knowing the formula is not enough. Liu Chang has been busy like this for four or five days. The gunpowder he made is getting finer and finer, and the color gradually matches the black gunpowder in Liu Chang's memory. Zhao Huan alone
I found a place to store the black powder.
After making enough portions, Liu Chang decided to test its effectiveness to see if he was successful.
He first placed the gunpowder in the dug ore, sealed it with stones, leaving only a fuse, and slowly stretched the fuse to a sufficient length before starting to ignite it.
Everyone hid far away, and Liu Chang covered his ears and stared excitedly, expecting the explosion to happen.
However, the fuse was burned to the end, and even after a long time, no explosion occurred.
Liu Chang was stunned for a moment, and then waited for a long time before going forward to check.
"Shouldn't it?"
"Does it have to be put in a jar?"
Liu Chang did not believe in evil and tried several more times.
Liu Ying and others were not in a hurry. Zhao Huan also watched carefully. After Liu Chang told the so-called explosion method, he did not dare to underestimate this child. Maybe he could really do it.
, and I don’t know which book he read it from.
"Bang~~~"
On the third try, with a muffled sound, thick smoke came out of the stone mine and several cracks opened. This movement scared the surrounding miners to scream and flee in all directions. Fortunately, the armor
The soldiers were not afraid and soon forced them to kneel down. The chaos nearby did not last long.
Liu Chang looked helplessly at the gap. God knows how much gunpowder he had just put in, but with this power, it was just a large firecracker. Just listen to the sound. The lethality was too low... Liu Chang originally thought
Can it be used on the battlefield? This power cannot even be used to scare the enemy.
The specific formula of this thing is really important, but Liu Chang doesn't dare to mix it randomly... Ahem, he's not afraid of being blown up, but his parents are still alive now. If a white-haired person gives a black-haired person,
How sad that would be.
Liu Ying was stunned again. He looked at the blasted iron mine and asked, "My eldest brother actually knows how to draw thunder?"
The eyes of those princes and others looking at Liu Chang were completely different. It may be due to the influence of the Qin Dynasty. The people at this moment are very superstitious, and the northwest, which is the future Liangzhou area, has become the leader in the superstition of the Han Dynasty.
It was not until the Eastern Han Dynasty that the government began a series of rectification activities targeting local sacrifices.
Therefore, in the eyes of many people, Liu Chang's method is a magical technique!
Liu Chang still had a grimace on his face, "Why did you just make a firecracker in the end? Oh, is there anything else that can be improved? Think about it, think about it..."
He tapped his temples and thought hard.
.........
At this time, Liu Bang, who was about to return to Chang'an, received a letter from the State of Yan.
The person who wrote the letter was of course Lu Wan. Lu Wan clearly stated in the letter that he had made a mistake some time ago and thought that his subordinate Zhang Sheng had contacted the Xiongnu. After he executed him, he realized the mistake and felt guilty.
, leaving his clan behind and preparing to make some compensation.
Looking at this letter, Liu Bang felt a little strange.
He really knew Lu Wan very well. The two of them had played together since they were born, and even after Lu Wan became King of Yan, the exchange of letters between the two had never stopped. Therefore, after seeing this letter, Liu Bang
Subconsciously I felt there was something wrong with it.
In the early days, Lu Wan sent a message saying that Zhang Sheng, his subordinate, had colluded with the Xiongnu, wanted to rebel, and was preparing to kill his clan.
That letter was normal, but now this letter... Although it looks normal, there is no greeting, no complaints like usual, and not even a joke. The whole text is too formal. Liu Bang even
Do you wonder if Zhang Sheng has already killed Lu Wan and replied to him under his own name?
Liu Bang hurriedly sent people to the Yan Kingdom to find Zhou Bo, who was chasing Chen Xi, and asked him to see if there was anything wrong with the Yan Kingdom.
"Ahem..."
After arranging this matter, Liu Bang coughed violently, and Zhao Yao on the side hurriedly stepped forward and picked up the medicine.
Liu Bang took the medicine and drank it in large gulps.
"The imperial doctor ordered that your majesty should not work too hard."
"I know!"
Liu Bang said angrily, and then looked at the servant of the Liang Kingdom aside, "Do you, the Liang Kingdom, have any fine wine?"
"Yes, of course there is...our famous wine here..."
As the servant was speaking, Zhao Yao interrupted him directly. He knelt in front of Liu Bang and said sadly: "Your Majesty! You are not allowed to drink alcohol!"
"The imperial doctor ordered that your majesty should not drink alcohol! Do not have sex with women! Do not overeat! Do not work too hard! Only in this way can you be cured!"
Liu Bang laughed and said disdainfully: "You can't drink alcohol, you can't enter the harem as beauties, you can't hold banquets, and you can't eat love meat... Then what is Naigong doing alive? It's better to die!!"
"Your Majesty is the co-owner of the world, how can you talk about life and death so lightly!"
Zhao Yao hurriedly dissuaded him.
The servant of the Liang Kingdom was a little at a loss and hurriedly knelt down.
This servant was the servant who betrayed King Liang. This time when Liu Bang came to Liang, he summoned this servant and asked him to serve him. People like Zhao Yao would definitely look down on this kind of betrayal.
The people like Rong ignored him at all.
"Forget it..."
Liu Bang waved his hand and asked the servant of the Liang Kingdom to leave and asked Zhao Yao to sit next to him.
"The world is finally at peace..."
Liu Bang sighed with emotion, and his eyes suddenly turned to Zhao Yao.
"This is all thanks to such an upright minister like Zhao Yushi... However, there is one thing that I really can't figure out, so I want to ask Zhao Yushi."
Zhao Yao looked at Liu Bang in surprise, wondering what he was going to say.
"You are usually upright and show no mercy to those who make mistakes, and you can always testify in front of them. However, I have heard that people under Jiancheng Marquis occupied people's fields and oppressed gentle people, but I have never heard you impeach them.
, why is this?”
Zhao Yao's face was pale, his mouth was pursed, his lips were trembling slightly, and he did not dare to speak.
"I...I'm going to call everyone to investigate this case when I return to Chang'an!"
"Hahaha, what are you afraid of? I'm joking!"
"Hahaha~~"
Liu Bang laughed, and Zhao Yao forced a smile, his face looking very ugly.
"By the way, that servant... I'll leave it to you."
