Seeing that the master built the iron horse completely, without damaging its internal structure, he took out a small "hole" for snooping, and Gan Xin understood the technique on the side, and also squatted down to help.

He has been with Zheng Quqi for several years, and over the years, he has focused on learning construction design knowledge and technical application, mainly laying a good foundation first, and then slowly forming his own style and habits.

However, the study of architectural structure was too complicated, and he always encountered such and such problems in the process of learning and practicing, but fortunately, it was the master who led him to get started, and he felt for the first time that he was not a piece of rotten wood.

No, maybe he was originally a piece of rotten wood, but the master was able to carve him into wood.

Because of the previous accumulation, he can also get busy, but his actions are relatively violent and rude, which stems from the style of doing things in his personality, so the fine Zheng Quqi does not ask him to touch it first, which saves him from recovery and destroys the integrity.

When they made a big hole in the "belly" of the iron horse, Zheng Quqi stopped, and then poked his head in, and even wanted to get into it directly.

Gan Xin looked at it and was startled: "Master, let me come." ”

Who knows what's inside, what's in it?

"No, I'll come, you can't understand it when you go in."

But Zheng Quqi looked confident, and said, she was extremely mobile, and she slipped into half of her body with a shudder, but the back half ......, "What's that...... Apprentice Gan, do me a favor, I will push the teacher forward. ”

A muffled voice came from within.

"Oh, what a ......"

Gan Xin saw that her legs were kicking wildly and couldn't reach the force point, so he pushed the soles of her feet and slowly sent her in.

Boom – There is the sound of heavy objects falling.

It was Zheng Quqi's center of gravity that was unstable and fell to the ground.

"Master, how is it?" Gan Xin shouted anxiously.

Someone inside immediately responded, "It's okay, it's okay, it's just that I didn't stand firm, it's still quite spacious in here...... Hey, what is it? ”

What is she talking about?

Gan Xin didn't understand what it meant, and leaned over to see what was inside, but he quietly retracted without noticing a square piece of wood, and then shot a sharp arrow with a "swish", which could be grazed from the tip of Gan Xin's nose.

…… If he had avoided it slowly, he would have already blossomed in his head by this time.

Gan Xin only felt his heart beating wildly, and a layer of cold sweat broke out on his back.

"I seem to hear the sound of some mechanism activating, Gan Xin...... Is there something going on out there, what's wrong with you? Inside, Zheng Quqi asked worriedly.

“…… Master, the next time you encounter something, you'd better explain it to your apprentice in advance, I'm almost gone. ”

"What's wrong?" Zheng Quqi's voice was a little anxious.

"That's supposed to be the mechanism that fires the bolts, and it's hidden in the body of this iron horse."

“…… Are you sure? Gan Xin, you go farther this time, and I'll try the others. ”

Gan Xin guessed that she must have found something in the iron horse, so she responded: "Okay." ”

After Gan Xin walked a distance, he shouted, "Master, it's okay." ”

After a short time, the "limbs" of the iron horse moved on its side, and its four feet walked from slow to fast in the air, although the wooden was stiff and the joints were not more flexible than the real ones, but it was able to walk purely by mechanical movements.

Then the horse's head suddenly sticks out with two warped horns, which are similar to the horns of a bull, but much larger, and more practically like two curved and sharp sickles, which swing from side to side.

If the iron horse is in the right position at this time, it can walk normally, and the speed is heavy, it will be like a bullfight, and if there is any other obstacle in front of it, I am afraid that it will be pierced and knocked away.

It also has hidden arrow traps in various parts of its body, fourteen locations, and a total of three rounds of fire.

The head and limbs can be detached, and the connecting rope can be split apart, dragging and tying the surrounding things.

After some research, Zheng Quqi finally climbed out of it, and Gan Xin hurriedly stepped forward and pulled him out.

After Zheng Quqi stood still, she said, "I finally know why it's called Iron Horse." ”

Gan Xin was puzzled: "Why?" ”

"Because it's all made of iron, except for the wood on the skin."

Gan Xin also suddenly: "...... No wonder it's so heavy. ”

She added: "It can hide a person to operate, there is an eye hole to observe the outside world, the whole body of iron is not afraid of swords and arrows, and its brutal body can be used as a weapon, or maybe as a means of transportation......"

Thinking about it this way, its role can be called the best "companion" for marching and fighting.

When the weapon is in use, it can be used as a crash to target large enemy weapons and cause crushing destruction.

Its multi-functional attack method can also deal with all kinds of military dangers, can hide people, can assassinate, can cover, can be used as a barrier, can be used as a sentry......

When it is a means of transport, it can set off with the army, put food, weapons, and all kinds of things needed, save rickshaw power, and can also hide people's eyes and ears.

Once the war began, the two armies fought against each other for two days and two nights, and the other side was hungry and thirsty, and was so tormented that he could not return to the camp in time to replenish supplies.

But they don't have this kind of trouble at all, who can guess that the other party's iron horse still hides all kinds of life supplies such as food, drink, and wound medicine, so that the comparison is superior, and the other party can survive just by boiling alive.

The master and apprentice looked at each other, and they never expected that if they still had such a ...... in their hands An indescribably warlike sharp weapon, this is simply more cheating than her cheating!

"So what now?" Gan Xin rubbed the corner of his forehead and asked.

The other party is not only such an iron horse, but a hundred heads, comparable to a strong ironclad army.

If, no, not if, it is a public loss, that is, if he is about to take his "iron horse" to the battlefield, I am afraid that some of the victories that Yu Wensheng has just won will come to naught.

Zheng Quqi was also anxious: "I can't imagine that the invention of the public can be ahead of today's science and technology for tens or hundreds of years, this iron horse is not easy to deal with, but I am afraid that the ballista is difficult to deal with, I have to think of a way." ”

Gan Xin asked: "Ballista can't work, what about artillery?" ”

"The cannon is naturally more powerful than the ballista, but it is still the original version, the rate of fire is too slow, and the number is small......"

"Attack with fire, Master asked me to investigate the matter of fierce fire oil before, the Wubao camp was set on fire, and some people took the opportunity to plunder the leader of the Zhu tribe and assassinate Yu Wensheng, all of which are related to the Nanchen people, and at the same time, I also found out an underground pit of fierce fire oil that has not been taken, if ordinary fire is not good, then what about using fierce fire oil?"

Zheng Quqi frowned, but still shook his head: "It's too late, it's useless to mobilize the fierce fire oil, the amount is useless, the maximum time and energy consumption, and the inside of the iron horse is all made of metal, and it is useless to burn off a layer of skin." ”

If the fire doesn't work...... Gan Xin looked at the towering snow-capped mountains, the cold and mighty thousands of miles, the vast peaks, and couldn't help asking: "What about the flooding?" ”

Zheng Quqi looked sharply into his eyes. (End of chapter)
