Walking more than a thousand meters further, you can see a large building. The figures are panicked, the fire is bright, and the sound of iron "kicking in the clang" is deafening, hundreds of people are busy here.

When I came to the front, there was a large square filled with all kinds of strange equipment.

The outer structure of wood, metal gears, and cores made of springs, include siege cars, catapults, and giant crossbows. A small number of them can be named, but most of them cannot even understand.

Especially an object similar to a glider, Li Wenhao was shocked and almost thought he had met a fellow villager...!

"Gu Yazi, come and see the General of the Western Expedition!"

Kubo ran to the group of people happily and pulled a fat old man out: "General, this is Master Gu Yazi!"

"Li Wenhao has met the master!"

Li Wenhao calmed down and bowed to Gu Yazi. This old man was not simple, and he was definitely at the level of an academician on Earth.

Gu Yazi looked in his early sixties, with a red face. Perhaps because he was often close to the stove, his skin was dark, and in general, he was a fat old man with a burly figure.

"You are Li Wenhao who liberated the slave. It's very good. Young man, you are a good person!"

When Gu Yazi saw Li Wenhao, the dissatisfaction on his face disappeared, but instead replied with a serious gift.

"I thank you general for restoring my freedom. Unlike some people, they say nicely, but they just don't do human affairs!"

"Gu Yazi, when did I treat you badly!"

Kubo immediately jumped up, just let it go if he didn't give him face, but today he actually embarrassed him in front of the general. It was so hateful!

"That fierce woman, wasn't you sent to bully me?" Gu Yazi seemed to be even more angry than Kubo, waving her fists, looking like she was about to beat someone up.

"A murderous woman?"

Li Wenhao was a little unhappy. How could a master-level national treasure still be bullied by women? He stared at Kubo and scolded him: "What kind of fierce woman dares to disrespect the master and execute him immediately!"

"Old minister will do it now!"

"etc!"

Unexpectedly, Kubo agreed very happily, but Gu Yazi opposed it, and looked anxious: "General, there is no need to execute him, otherwise, be my wife!"

"Be a wife!"

OK, now it’s Li Wenhao’s turn to be confused. What kind of magical operation is this? He was so angry that he gritted his teeth. Why did he become a wife after turning around?

"Who, after being bullied for a long time, I have to bully you back!" Gu Yazi blushed, and the old man in his sixties actually saw shyness.

I go, this old man is afraid that he is not masochistic!

"Hey, you can't be a good person these days!" Kubo sighed, looking very unjust, and seemed to be not surprised by Gu Yazi's changes.

"Master Gu Yazi, this time I came to appoint you as our army, the chief craftsman.

There is another important thing. Our army will set out tomorrow afternoon to attack the Langya King City. I wonder if you have any ready-made siege equipment here."

Time is tight and after getting to know each other, Li Wenhao immediately got to the topic.

"It'll be tomorrow afternoon?"

Gu Yazi shook his head when he heard this: "There are only one siege hammers and a few trenchers ready-made, and only one day is too little.

I have been to the royal city, and it is definitely not enough to rely on these alone!

Otherwise, [567 Chinese www.yue20.com] I will take these disciples with me and go with the army tomorrow. The general will recruit more craftsmen. As long as the materials are sufficient, within two or three days, he can build twenty trench machines and hundreds of stairs to climb the city!”

"This is OK!" Li Wenhao frowned and thought for a while. Although it was a bit dangerous to let Gu Yazi accompany him, at present, this suggestion is the most feasible.

After all, no one knows what will happen to this Langya King City for a few days to attack.

Gu Yazi followed the army and was able to adjust the types of equipment at any time according to the actual situation on the scene, so as not to delay military information.

"Since the general agrees, I will prepare now and create more metal movements, and then install them with external structures to use them."

"Wait a minute!" Li Wenhao called Gu Yazi who was about to leave and took out a drawing from his arms.

"Master Gu will show you, this is a picture of Huo* I drew. I wonder if I can create several pieces overnight!"

This is the world of cultivators, and most of the craftsmen are cultivators, so it is not difficult to build a cannon with a simple structure.

"Are you a black iron cannon?"

Gu Yazi only glanced at it, shook his head and denied it repeatedly: "General, a black iron cannon requires two thousand kilograms of black iron, as well as precious metals such as black silver and black gold, which cost nearly 100,000 taels of gold, which is too expensive!

When using it, many Qi training men need to replenish spiritual power for the cannon, which is suitable for naval battles, but not for land battlefields.”

"Master Gu, take a closer look. My cannon is only 500 kilograms and does not require valuable materials such as Xuanjin. Moreover, it does not use spiritual power, but uses gunpowder!" Li Wenhao explained patiently.

"Gunpowder, no, gunpowder cannot do it, gunpowder is too weak!" Gu Yazi shook his head even more happily when he heard the gunpowder. He also conducted an experiment on the spot. When he stretched out his left hand, a handful of black gunpowder appeared on the palm of his hand.

The spiritual power was ignited, and a muffled "bang," sounded like a match head burning, with no power at all.

"General, the power of gunpowder is really too small!" Kubo also spoke on the side.

"The gunpowder I'm talking about is not the commonly used gunpowder, but this!" Seeing that it was unclear, Li Wenhao simply took out a small bag of solid powerful explosives produced in the system.

The gunpowder in this world is very small. He asked the system because it was affected by spiritual power. Not only creatures, but also all matter have undergone some changes.

The formula of gunpowder remains unchanged, but it is much weaker and is almost useless.

The powerful explosives produced in the system use different formulas and materials.

What exactly is it? The system asked him to explore it by himself. So Li Wenhao thought of Gu Yazi.

It would be even better if the formula of the system explosive can be cracked!

"This is gunpowder!"

Gu Yazi was very surprised. He broke off a piece with his hands, put it under his nose and smelled it, nodding: "It does smell of gunpowder, and there are spiritual power fluctuations inside."

"Master Gu, I also got these gunpowder unexpectedly. Can you tell the ingredients of it?" Li Wenhao asked in a low voice with some nervousness.

"I can be sure that there is fire raystone powder here, and the others are not clear yet. Some experiments are needed to judge!"

The master is worthy of being a master. Gu Yazi just smelled it with his nose and determined a material.

Just as Li Wenhao was about to praise him, he suddenly changed his face and a light of inspiration in his hand sounded: "Don't light the fire, throw it away!"

"Boom." Unfortunately, there is no hurry to come. Gu Yazi and Kubo have been blown into the sky.

"Damn it!" Li Wenhao was anxious and sweated in his forehead, and he flashed and chased Gu Yazi.

Gu Yazi is only at level 3. If something happens at this time, it will be a tragedy.
