Although the gunpowder made last time was not satisfactory, it was a success after all, so although Zhao Zheng did not personally take action in this mass production, he was not too worried about its quality, after all, he knew in his heart that the black powder made under such simple conditions was rubbish, a bunch of gunpowder that could not be called gunpowder in the strict sense, even if it was bad, how bad could it be?

Zhao Zheng looked at the black powder full of five pottery jars and couldn't help nodding and praised: "Very good, it's not easy to make it like this for the first time!" This gunpowder manufacturing is also a university discipline in geoscience, and when you reach the university level, you will be taught according to your aptitude and diverted from each other, and then you don't know which of you will specialize in gunpowder research and development. ”

Feng Youcai and the others were naturally overjoyed when they were praised by Zhao Zheng, but they said that when Zhao Zheng's words just fell, they suddenly heard someone in the room shouting: "Master, the apprentice is willing to study this technique!" ”

When Zhao Zheng heard Shen Lang's voice, he couldn't help but say with a black line: "You old boy, your thirsty attitude is very valuable, but this appearance is inevitably a little ugly, and if you are greedy and don't want to learn everything, don't make it too good, then it's troublesome!" The teacher asks you, what are you interested in in all your days? ”

"Oh, yes, you guys think about it too!" Zhao Zheng turned his head and said to Feng Youcai and the others.

"Hmm......"

When everyone heard Zhao Zheng say this, they all fell into contemplation, and after half a cup of tea, Shen Lang shouted: "Back to Master, the apprentice has been interested in the theory of ghosts and gods since he was a child, Master, you are an old man......"

"Shut up, bastard!"

Before Shen Lang finished speaking, he was interrupted by a sudden scolding, "Just the fucking said that you were not greedy enough, and you still gasped!" The earth art has not been learned to the slightest centimeter but wants to spy on the heavenly machine, it doesn't count, start again! Zhao Zheng angrily jumped to his feet and yelled at the broken house.

Seeing that Shen Lang was scolded without opening his eyes, everyone felt ridiculous but didn't dare to laugh out loud, so they had to hold it back in their hearts. Shen Lang was silent for a moment after being scolded, and then asked weakly: "The apprentice has liked the blades of knives, guns, clubs, and blades since he was a child, I don't know if it's okay?" ”

Zhao Zheng grinned when he heard this: "This is almost the same!" You don't have these things for the teacher, but there will be a lot of things similar to guns in the future, and then it will be enough for you to play in this life! ”

"Shhh...... Firearm? ”

Everyone naturally didn't know what the "gun" in Zhao Zheng's mouth was, so that everyone could only look at Zhao Zheng blankly after hearing it. Seeing this, Zhao Zheng immediately made a fool of himself and said: "These two artifacts are still far away from you, and after you pass the university stage, your senior brothers who specialize in this art will definitely be made under the guidance of your teacher!" For now, everyone can only make do with the cold weapon in their hands first! ”

"Cold weapons?"

Although Feng Youcai and the others had heard of this word for the first time, they all knew that Zhao Zheng was referring to the Qin short knife on his waist. Everyone subconsciously touched the blade with their hands, and then felt a faint coolness at their fingers. As if suddenly realizing something, everyone stared at the five large clay jars with blazing eyes.

Zhao Zheng smiled and said nothing when he saw this, looked up at the sky, and saw a cloud like red silk hanging in the sky, "'Don't go out in the morning, go out in the evening', it seems that it will rain again in a while!" Zhao Zheng saw that there were burning clouds in the sky early in the morning, so he knew that there would be another continuous rain in a while, and then shouted to everyone: "Hurry up and carry the gunpowder there, this thing will not be good when it encounters water, quickly!" Everyone suddenly heard Zhao Zheng shouting eagerly, so they didn't think about it, and they lifted the clay jar in pairs and walked out of the courtyard. Just as Zhao Zheng and the others were carrying gunpowder towards the pile of broken corpses, at the house of Old Doctor Liu, Zhang Mancang was sitting on the edge of the bed and meditating silently.

Although dozens of soldiers were inexplicably folded in the city yesterday, the news that Li Xi brought back meant a lot to Zhang Mancang! At the very least, at this time, he knew that there was still a group of "Xuan" people in the city who were potential in the city, and more than half of the ordinary Qin army prisoners had been lost! As for the pile of broken corpses in the ruins of the west of the city, Zhang Mancang actually didn't take it to heart, and he didn't even mean to send troops to collect the corpses again. At this time, he hoped that the stinky meat would rot quickly, so that the "Xuan" and the criminals in the potential ruins would slowly contract and die, and as for the life and death of the common people in Nancheng, Zhang Mancang was also not very concerned.

Ten minutes later, Zhao Ji brought a pair of dishes and chopsticks to Zhang Mancang, and Zhao Zheng and the others also came to the corpse pile again.

As Zhao Zheng expected, Zhang Mancang did not send anyone to collect the corpse again, and compared with yesterday, the corpse pile at this time was even more fragmented and rotten. "Master......" Feng Youcai covered his mouth and nose with his hands and said with a disgusted expression: "I really let you say it, this Zhang Mancang is really damned!" Could it be that he is not afraid that the people in this city will be infected with the epidemic? ”

Zhao Zheng also covered his mouth and nose and replied: "The north and south cities of Handan City are separated by the Qin River, and although the royal city is west of the South City, it is located in the upper reaches of the Zhu River, which is relatively independent!" And so on...... Hehe...... As long as it is not infected to the princes, nobles, and dignitaries of the Da clan, the life and death of these commoners are naturally not so important to them! Not to mention...... Hmph......" Zhao Zhengxu squinted his eyes and snorted coldly: "What's more, that Zhang Mancang must still want to use these stinky corpses to force the 'Xuan' and the Qin army prisoners out of this waste!" ”

Speaking of this, Zhao Zheng waved his hand at Feng Youcai and said, "Find some firewood to cover it, and then sprinkle all these five cylinders of gunpowder on these dead corpses, and finally light the fire!" ”

"Yes!"

Feng Youcai answered, and then waved behind him and shouted, "Quick!" And they scattered. After several moves, half an hour later, the corpse was covered with a thick layer of firewood.

Fortunately, at this time, the corpse was partially eaten by the rats for two nights, and although it was very disgusting, everyone still forcibly scattered all the gunpowder on the meat stall.

"Ignition!"

After the gunpowder was exhausted, with Feng Youcai's soft drink, several torches were thrown into the fire.

"Boom!"

The blazing torch fell into the dead body in public, and suddenly the flames were shining, the smoke of gunpowder rose, and the firewood covering the slight moisture on the body actually burned so that it was extremely lively.

The large amount of light, heat, and smoke produced by the gunpowder stunned everyone, and before long, a puff of extremely pungent and unpleasant black smoke rose into the sky and went straight into the sky!

Maybe the amount is a little bigger, maybe the purity has improved this time compared to the last time, Zhao Zheng didn't expect that there would be such a big movement this time. Looking at the fire that became less and more intense, a sense of uneasiness suddenly surged in my heart, "Quick, hurry up!" Zhao Zheng shouted.

Feng Youcai and the others seemed to be shocked by the scene in front of them, and Zhao Zheng's shouts did not drag them back, they still stood there in a daze......
