The corners of Chen Yan's mouth twitched, and he kicked away Li Wu, who was holding his thigh, his face as black as the bottom of a pot.

"You useless thing, you threw out the earth-shattering thunder just now, you're afraid of a chicken."

As he spoke, Chen Yan walked to the edge of the big pit and looked at the effect of the earth-shattering thunder explosion.

The bushes on the ground were gone, bare, and the ground around them, on the stones, on the trees, there were small pieces of iron nails and stones.

Chen Yan's pupils shrank, and these iron and gravel pieces began to shake the most terrifying part of the thunder, once they were hit by these iron nails and gravel blocks, the wound would be 100% inflamed.

In this era when antibiotics do not even have a shadow, wound inflammation and death are equated!

"See, this is the weapon I have for you."

Chen Yan turned to look at the villagers who were paralyzed, and said in an impassioned tone.

But everyone had a look of disbelief.

"Sir, isn't this God thundering? How could it be the weapon you prepared for us? ”

"Yes, sir is not stupid."

"How can thunder be used as a weapon?"

“……”

Chen Yan's face darkened.

"Look at them all!"

As he spoke, he took out another sky-shaking thunder, and under everyone's gaze, he personally lit the fuse, and then threw the sky-shaking thunder.

Bang!

There was another earth-shattering sound, everyone knelt on the ground and trembled, even Li Wu, who was usually the most courageous, turned pale and almost peed his pants.

In the open space in the distance, a large crater appeared out of thin air again!

"Sir...... What you say is true? ”

"Is this really the weapon you gave us?"

"Sir, if you really go down to earth, long live Sir!"

“……”

Chen Yan's face darkened again, and he took these people to a black/gunpowder workshop, and took out a part of the Heaven-Shaking Thunder, as well as some stones of similar size to the Heaven-Shaking Thunder.

Chen Yan personally demonstrated the experiment several times, and told them the precautions, asking them to practice how to throw stones first, and then use the real earth-shaking thunder after the movements are proficient.

When they learned that this Heaven-Shaking Thunder was really a weapon, and Chen Yan asked them to use the Heaven-Shaking Thunder to deal with the imperial court officials and soldiers, these people were excited!

In their opinion, the more powerful the weapon, the greater their chances of surviving the encirclement and suppression of the official army!

After personally teaching Li Wu and Wu Sanshun to use the Heaven-Shaking Thunder, he arranged for the two to be responsible for teaching others. After that, Chen Yan left there, he still had things to do, and it was impossible to teach everyone by hand.

Chen Yan returned to Liu Yueying's courtyard, and as soon as he walked into the courtyard, he saw that Liu Yueying happened to walk out of the door, holding a long horse lance in her hand, and wanted to walk to the school field where she practiced.

"Yueying, what are you going to do?"

Chen Yan blocked Liu Yueying's way and asked in a soft voice.

"I'm going to drill and avenge my father in the future!"

"Your Body ......"

He stopped talking.

"I'm fine, don't stop me!"

Liu Yueying's attitude was very resolute, and seeing this, she no longer stopped Liu Yueying, and turned sideways to let Liu Yueying pass.

Liu Yueying walked past Chen Yan, and just as she was about to step out of the courtyard, Chen Yan suddenly said.

"Lady, I have a book of soldiers, do you want to learn it?"

Liu Yueying's footsteps froze, and the expression on her face instantly became extremely expectant, and she pricked up her ears and waited for Chen Yan's next words.

However, after Chen Yan finished saying this, he slowly walked towards the room step by step, without any intention of continuing.

Liu Yueying turned her head, watched Chen Yan walk back to the room, stomped her feet, snorted, and strode after him.

"Xianggong, what kind of military book?"

Liu Yueying asked.

Chen Yan smiled without saying a word, and sat back behind his desk.

"What kind of military book is it?"

Liu Yueying asked.

"You rest first, I'll write it on paper, and you can read it slowly for yourself later."

Chen Yan said unhurriedly.

Liu Yueying's pretty face was full of anxiety.

"Oh, hurry up, don't fish my appetite!"

"Two hours, you go and rest for two hours."

"Xianggong~"

Liu Yueying said delicately.

"Two hours, no discussion."

Chen Yan picked up the pen as he spoke, and neat lines of regular script appeared on the paper, and he wrote by himself, no longer paying attention to Liu Yueying.

Liu Yueying was helpless, stomped her feet and had to rest.

Seeing this, Chen Yan smiled slightly, and continued to lower his head to write, the military book he wanted to transcribe was the "New Book of Ji Xiao" by Qi Jiguang, a famous general in the Ming Dynasty in the later generations.

"Ji Xiao Xinshu", one of the pinnacles of the cold weapon era, which is also mixed with a part of the firearms use code, currently seems to be the most suitable military book for Erfengshan to learn from.

Because Erfengshan, like the Qi family's army, for a period of time, was mainly based on cold weapons, supplemented by firearms.

Before Chen Yan was able to produce on a large scale and equip himself with firearms, "Ji Xiao Xinshu" was definitely his best choice!

……

Liu Yueying rested obediently for two hours, and Chen Yan also kept his promise and handed over the "New Book of Ji Xiao" he copied to Liu Yueying.

It's exactly the same as the original, that's impossible, and when Chen Yan read "Ji Xiao's New Book" in later generations, he just looked at a novelty, and there were many things that were turned at a glance.

At most, Chen Yan can only ensure that the general content remains the same! The language is definitely different.

Liu Yueying took the military book that Chen Yan gave her, and trained the soldiers according to the training method on the military book, Chen Yan came out of the room and found Ma Liu.

"Uncle, do you have anything to do with me?"

Ma Liu said with an extremely respectful attitude.

Chen Yan rolled up his sleeves and asked.

"How's it going?"

"What's the matter?"

"The matter of recruiting craftsmen."

"Oh, that's already in the works, it's just ......"

"Just what?"

"The wages were very high, and I almost doubled them before the craftsmen reluctantly agreed to come to the cottage with me."

"If the salary is high, it doesn't matter, how many people have you brought back?"

Chen Yan touched his chin and asked.

"About twenty or thirty people, mostly blacksmiths, masons and carpenters."

"Where are the people? Brought them to me, and all the original craftsmen in the village also called me. ”

Chen Yan said.

Ma Liu went to take the craftsman in response, and Chen Yan returned to the room, and he wrote down the glass-making methods, steel-making methods, cement production methods and other things in his mind.

Prepare to hand it over to those craftsmen and let them study it and make it as soon as possible!

As for whether those craftsmen will cause the leakage of those secret recipes after leaving the cottage?

Hehe, Chen Yan said that he was not worried at all, those craftsmen could leave the cottage first!

I'm a thief, alas, the kind of bad pus, since I've entered his Chen Yan's den of thieves, do you still want to leave?

Dreaming baby?!

It didn't take long for Ma Liu to "invite" the craftsmen who came back, including the original craftsmen in the village, all came to Chen Yan.

Looking at the dozens of ragged men in front of him, Chen Yan stood up, cleared his throat and said.
