Shen Lang looked at Zhao Zheng excitedly, and then asked very suspiciously, "Master, didn't you go to the crematorium, why did you come back?" ”

Zhao Zheng thought of the scene he had just seen, and his stomach churned involuntarily: "Don't mention it, those nearly 100 corpses have been gnawed to pieces by wild dogs and rats in less than a week!" ”

When Shen Lang heard this, his face suddenly became extremely ugly: "Master, your old man is right, compared to being eaten by rat wild dogs, this cremation is indeed thousands of times better!" But ......" Shen Lang wondered, "But what does this have to do with making gunpowder?" ”

Zhao Zheng replied: "Those corpses have long been fragmented, and the corpses are piled up a hundred meters square, so it is impossible to effectively concentrate them, so it is not realistic to use ordinary firewood to burn them in a time-consuming and laborious manner!" So the teacher wants to burn it with gunpowder! ”

In Shen Lang's impression, gunpowder is a big killing weapon that kills people by exploding, and he doesn't know that it can also be used for arson, but after tasting the word "gunpowder" carefully, he seems to understand some of the truths.

"But Master......" Shen Lang pointed to himself and said helplessly: "But the apprentice is in this state now, he can't move, I'm afraid he can't learn......"

"It's okay, in fact, this inferior black powder is very simple to make, and the materials used are also extremely easy to find, as a teacher, you just need to tell you the ratio relationship between the materials!" Zhao Zheng waved his hand.

"Low ...... Inferior black powder ......"

Shen Lang saw that Zhao Zheng called this kind of big killing weapon inferior black powder, and he couldn't help but feel a pang in his heart: "Such a divine object is only worthy of the word 'inferior'?" ”

Zhao Zheng saw Shen Lang looking at him with a shocked face, smiled slightly and asked, "Does Lang'er know how far an arrow can shoot?" ”

"It's nature! A light bow can take more than 100 steps, while a heavy bow can reach hundreds of steps! Shen Lang replied.

"Hundreds of steps away......" Zhao Zheng smiled slyly at Shen Lang and asked, "Lang'er, do you know how far that high-grade gunpowder can throw objects?" ”

Where did Shen Lang know these things, so he had to shake his head slightly, Zhao Zheng gestured with both hands: "More than 100 catties of heavy objects are easily dozens of miles away, if you use the range extension technology, it is not impossible to break through 100 miles!" ”

Zhao Zheng's words shocked Shen Lang completely: "If this is the case, then how can this battle be fought?" ”

"Therefore, if you wait to learn the art of earth diligently, then the destruction of the city in the future will only be a matter of moments!" Zhao Zheng said indifferently.

Shen Lang muttered a little in his heart at this time, although he didn't dare to say that he was questioning Zhao Zheng, but he always felt that this was a bit exaggerated, "In that case, why doesn't Master directly teach the disciples to be high-end, wouldn't it be troublesome?" ”

Zhao Zheng couldn't help but laugh dumbly when he heard Shen Lang say this: "You old boy, do you think this is a dinner on the table, and it is delicious?" Zhao Zheng patted Shen Lang and continued: "You must also know that everything must be based, you have to take your time, you can't rush!" Now that the system has not been built, even though the teacher has the merit of turning over the river and the sea, and destroying the world, he has only ended up with a clever woman who can hardly cook without rice! You know, this high-grade gunpowder is only thousands of times more difficult to make than that cosmetics! ”

"A thousandfold ......"

Shen Lang instantly languished when he heard Zhao Zheng say this, "If you follow what Master said, the apprentice must not be able to see it in this life." Shen Lang said stupidly.

"That's not necessarily, the so-called art industry has a specialization, and this system can not be supported by just one person's strength, and after a batch of earth art seeds are taught by the teacher, they can expand and gradually grow! So Lang'er, your progress directly affects the decision of the teacher! Zhao Zheng sighed when he heard this.

"What the master said is very true, we will definitely live up to the master's kindness!" Shen Lang said.

Just as the master and apprentice were talking, Feng Youcai and the others brought back a bunch of firewood and grass and came back: "Master! Feng Youcai put aside the firewood and grass and asked, "Master, this firewood and grass are easy to obtain, but the nitrate and sulfur stones are not easy to find in the city, can the apprentices go out of the city to find them?" ”

"At present, the tattoos on your face have not been eliminated, and I will talk about it in the future, you wait until you touch it in the pharmacy tonight, presumably there should be two stones of nitrate and sulfur there!" Zhao Zheng replied.

Hearing this, Feng Youcai asked again: "Master, the apprentice has a doubt in his heart, I don't know if I can invite the master?" ”

"Oh?"

Zhao Zheng glanced at Feng Youcai with some surprise and said, "If you have something to say, just say it!" ”

Feng Youcai arched his hand and said: "Those corpses were gnawed into that shape overnight, even if we wait for the gunpowder to be made, I am afraid that the remaining residues will no longer need us to burn them." What's more, in case Zhao Bing goes to collect the corpse and we encounter it again, hiss...... I'm afraid that it will be more auspicious! ”

Zhao Zheng replied when he heard this: "What Youcai said is very true, but this corpse has to be burned, otherwise in the future, if there is an outbreak of epidemic here, we will bear the brunt!" As for Zhao Bing...... Hehe, they must have been there a long time ago, and the corpses are still there, so they won't set foot in the ruins of the west of the city for a while! ”

Feng Youcai felt quite reasonable when he heard Zhao Zheng say this, and then turned his head to look at the firewood and grass pile and asked, "In this way, then Master can see that these firewood and grass are enough?" ”

Zhao Zheng looked at the courtyard and replied: "Let's get these for the time being, you can rest for a while, and then talk about it when it's dark!" When Feng Youcai and the others heard this, they each found a place to sit down, and after everyone sat down, Zhao Zheng asked again: "How do you solve the problem of eating on weekdays?" ”

Shen Lang shook his head helplessly when he heard this: "Except for the last time I had a full meal because of my master, I can only live hungry again in the past few days, and I can't be hungry before I go to touch some food at night......"

When Zhao Zheng heard Shen Lang say this, his heart suddenly felt uncomfortable as if he was being pulled: "Everyone endure for a few more days, the tattoos on your face are gone, and you will do a great job for the teacher, and you will not have to worry about food and clothing from now on!" All you have to do is study with peace of mind! ”

Everyone didn't know whether Zhao Zheng was comforting themselves or painting them a big cake at this time, out of absolute trust in him, although they did not express their position, they all chose to believe Zhao Zheng again. Zhao Zheng saw that everyone did not respond, thinking that there was a crisis in his prestige, so he became anxious again, "It seems that Lao Tzu has to do it as soon as possible!" ”

No one answered, and the atmosphere became more and more awkward, Zhao Zheng wanted to change the topic to relieve the atmosphere, but just as he was about to speak, he found that these ten people had fallen asleep leaning on the broken wall. Zhao Zheng didn't get angry when he saw this, he knew that it was already very valuable for these people to follow him hungry.

"Lang'er, you can rest for a while!" Zhao Zheng slowly stood up and said to Shen Lang.

Zhao Zheng sighed slightly: "Go back and collect some food for the teacher, and I'll be back in a while!" After finishing speaking, Zhao Zheng walked out of the dilapidated house.

Looking at the firewood and grass piled up like a hill in the dilapidated courtyard, Zhao Zheng's face became more and more solemn......
