Yang Guang also felt that Li Mu looked at him a little wrong, and his eyes looked a little like that. Sometimes he was too tired to handle government affairs during the day. When he got to Queen Xiao, Queen Xiao looked like that he was disgusted with him.

"My dear, is it that what I said is wrong?" Yang Guang asked with some doubts.

Yang Guang felt that what he said was fine? If these big iron lumps that were more than three feet tall and one meter long and wide were crushed on the battlefield, wouldn’t they be able to drive the enemy into meat paste?

"Your Majesty, if you rely on crushing to kill the enemy, wouldn't it be more convenient to build a few large iron balls?" Li Mu joked.

"Hey, my dear, it's wrong for you to say that."

"Although this iron ball rolls quickly, the thing is too smooth, and after rolling, it will not be enough. This iron cow is better, it can advance, retreat, and walk and stop. Moreover, this thing is so majestic. When the enemy sees a large iron cow that is more than three meters tall, even if it is not crushed to death, it will be scared to death." Yang Guang said seriously.

Li Mu was joking about Yang Guang, but Yang Guang became serious and said seriously.

Li Mu's face turned dark now and thought to himself, "Good guy, I'll make you a joke, you'll analyze it. Don't say it, hurry up and roll the ball. Fortunately, I'm a big cow. If I make a smaller calf, I'll be out of your mouth, then I'll be out of the way."

Li Mu had a dark face and explained: "Your Majesty, this bull cart is not about crushing and killing the enemy. If I spend 36,000 taels of gold, I will create such a thing. Without you, I will just find a crooked tree to hang myself."

Yang Guang: "???"

"My dear, this is not up to crush and kill the enemy, so how should we kill the enemy?" Yang Guang was wearing a black question mark on his face. His confident guess was wrong.

Li Mu straightened the drawings and placed the part on the drawings after the completion of the chariot in front of Yang Guang. That means, you can take a closer look and see clearly.

Li Mu pointed to the eyes of the ox cart and asked, "Your Majesty, do you know what this is?"

Yang Guang looked up and looked like you treated me as an idiot. This is a fucking eyeball. Let alone him, only three-year-old children know it?

"Eyes? Isn't this a cow's eyes?" Yang Guang asked.

Li Mu pointed to the cow's eyes and explained to Yang Guang: "Your Majesty, the ox cart is three meters long and three meters long, and the height is more than one meter wide. Do you know how big the eyes of this cow are?"

"How old is it?" Yang Guang asked curiously.

"Your Majesty, this bull's eye bead is as big as a head. This eye bead is made of solid fine iron, and there is a mechanism hidden in the bull's eyes. As long as the mechanism inside the bull's cart is pulled into the mechanism, these two head-sized eye beads can eject more than ten feet." Li Mu explained to Yang Guang.

Yang Guang: "???????"

Zhang Heng: "???????"

Yuwen Chengdu: "??????"

At this time, except for Li Chen, the rest of the people in the imperial study were all stunned.

Now this scene can be described in one sentence, and Yang Guang and his friends were shocked.

"Huh! Huh! Huh!"

At this moment, the sound of gasping in the Yu Study was full of smoke.

Yang Guang is the emperor on the horse. He has experienced the scenes on the battlefield. He shot an iron ball the size of a human head for more than ten feet away. Isn’t this a closer stone caster? But this bull cart can move, and the iron ball is much heavier than a stone, so it naturally has much more power.

This is a mobile and invincible enhanced trench tool.

Before the three of them recovered from the shock, Li Mu continued to point to the nose of the bull cart and said, "Look at your Majesty, what's wrong with the bull's nose?"

Yang Guang thought to himself: "What's wrong with this bull's nose?"

While thinking, Yang Guang looked at the drawings of the bull cart. He didn't notice it if he didn't look carefully. After a closer look, he saw that the bull's nose was really abnormal.

The nose of the big iron cow on the drawing is different from the normal bull's nose. The nose of the iron cow is a nose facing the sky. It is not facing downwards, but slightly raised and its nostrils facing the sky. The most important thing is that in these two large nostrils, there are nine small holes in each nostril.

The big iron cow has a nose facing the sky, and it has a large nostril with a small nostril.

"Your Majesty, this bull's nose can shoot arrows as thick as an arm, and two nostrils can shoot 18 giant crossbow arrows at the same time." Li Mu continued to introduce.

"Huh! Huh! Huh!"

"Huh! Huh! Huh!"

Yang Guang, Zhang Heng, and Yuwen Chengdu made another sound of gasping for a cold air.

Before Yang Guang and the others could speak, Li Mu pointed at the bull's mouth and continued to introduce them: "Your Majesty, look at the bull's mouth. The bull's mouth contains tung oil. The person in the bull's cart pulls the mechanism inside, and the bull's mouth can spray flames and burn the enemy through the flames."

After Li Mu introduced the ox mouth, he introduced the three ways of killing enemies in this ox cart. Then Li Mu looked at Yang Guang quietly, and Yang Guang also looked at Li Mu quietly.

Yang Guangxin said: "You continue to say that there are still things that have not been introduced? It's awesome, why don't you introduce them? You can brag so much, can't you introduce them in detail?"

Did Yang Guangxin and Li Mu say it? To be honest, I don’t believe it. When Li Mu introduced this iron ball and crossbow arrow, Yang Guang believed it. After all, this principle is similar to a stone catapult and a crossbow chariot. However, when introducing this fire spitting, Yang Guang couldn’t understand it. After all, there was no such thing as a fire spitting in the Sui Dynasty.

Yang Guang thought to himself, why? Physical attacks can no longer satisfy you, right? This is a magical damage?

Yang Guang felt that the existence of this bull cart had caused him to be humiliated for ten years.

"My dear, isn't this flame hurting people a bit incredible?" Yang Guang asked hesitantly.

Yang Guang thought to himself, I heard from Mr. Storyteller. When Mr. Storyteller told that myth, when the heavenly soldiers and generals subdued the monsters in the world of cholera, the monsters could spit out fire.

"Your Majesty, this iron cow's fire-breathing is actually a mechanism to spray tung oil out and then ignite it before the tung oil lands. This way it looks like an iron cow's fire-breathing." Li Mu explained to Yang Guang.

Yang Guang: "I didn't understand. But if this thing is made, it will definitely be invincible in the world."

Li Mu thought to himself, although your ten years of hard work have lasted more than my nine years of compulsory education, it seems a bit useless?

Li Mu thought to himself: "It is not necessarily true that the world is invincible. If you encounter a monster like Li Yuanba, you may be able to beat him a few hammers."
