The officials in Tianjin looked at the huge chariot parked on the school ground in amazement, full of suspicion.

The huge chariot was two meters high, more than two meters wide, and three or four meters long. To the surprise of Huan Yihua and the others, the outside of this chariot was actually wrapped in a thick layer of steel armor. The steel armor was made of high-quality steel from the Fanjiazhuang Steel Mill, and the outside was coated with a layer of gray paint.

The front of the car is prismatic and protruding, making it look indestructible.

Huan Yihua, the general manager of the newspaper, turned around the front and back of the chariot and asked suspiciously: "I have seen the chariot pulled by these two horses, and I have also seen the chariot pulled by four horses, but why are there no cattle and horses in front of this chariot?" ”

When all the officials heard Huan Yihua's words, they all circled around the chariot one by one. But after looking at it for a long time, the people couldn't find any place to put the cattle and horses.

Huan Yihua found an iron door on the side of the chariot. His eyes lit up, and he reached out to pull the iron door, but found that he couldn't open it no matter what, and locked it.

Minister of Political Affairs Xie Liangyou turned around the front and back of the chariot, knocked the strong steel plate on the chariot, and finally said: "Do you pay attention, the wheels of this chariot are all hidden under the steel plates, and they are so deeply protected." ”

Defense Minister Hong Chengchou blinked, reached out and touched the tire under the chariot, and said: "It's so strong, this is not an pneumatic tire, this is a solid rubber tire." Even if it is hit by a bullet, this solid tire can continue to move forward. ”

Only then did everyone notice the position of the wheel, and they lay on the ground to look at the hidden wheel, and marveled.

"The defense of this chariot is really strong, and even if it is besieged by rifles, it will not get in the way."

"I just don't know how it moves."

Huan Yihua suddenly slapped his face and said, "I know, it must be the person sitting in the chariot who pushed the chariot forward from the car." ”

Everyone was stunned and thought about it.

Hong Chengchou shook his head and said: "I don't think so, this chariot is so heavy, I'm afraid it can't be pushed with manpower." ”

Everyone pondered for a long time, but they couldn't figure out the method of this chariot, and they all looked at Su Laosan, who made this chariot.

Su Laosan looked at the puzzled officials and laughed. He tossed the door key in his hand and said, "Can't guess how this chariot moves?" ”

Everyone shook their heads again and again, and said, "I don't know, Manager Su dialed and dialed me." ”

Su Laosan smiled and said, "This doesn't work, I won't drive this tank to you until the king comes!" ”

Everyone was helpless, so they could only suppress their curiosity and wait for Li Zhi to come with peace of mind.

After a quarter of an hour, Li Zhi slowly rode over from Tianjin City.

When everyone saw Li Zhi, they fell down one by one. Li Zhi waved his hand and made everyone stand up.

Li Zhi jumped off his horse in front of the chariot and looked left and right at the chariot.

He turned to Su Laosan and asked, "This steam tank experiment was successful?" ”

Su Laosan replied: "If you go back to the prince, it is basically a success." After a pause, Su Laosan said again: "It's easy to break if you drive it for a long time." ”

Li Zhi asked, "How long will it take to break down?" ”

"If you drive about one or two hundred miles, there will always be problems somewhere."

Li Zhi smiled: "That's okay. I don't need him to drive so far, I usually use oxen and horses to pull in front, pull them to the battlefield to unload them and unload them, and I can sprint for one or two miles. ”

Su Laosan replied: "There is definitely no problem in opening one or two miles. ”

Hearing the words of Li Zhi and Su Laosan, everyone knew that this tank was called a tank.

Hong Chengchou's eyes lit up, and he couldn't help but ask curiously: "Lord Wang, isn't this tank used to deal with the Jiangbei Army?" ”

Li Zhi nodded and said, "It's used to deal with the Jiangbei Army." ”

Huan Yihua hurriedly asked: "Lord Wang, how can this tank be moved if it doesn't use cows and horses?" Is it possible to use people to push from behind? ”

Li Zhi said with a smile: "With such a heavy chariot, it is impossible to push it by employing people." Don't you see the chimney on the chariot? ”

Only then did the crowd notice that there was a chimney at the end of the chariot facing upwards. The chimney mouth is not exposed above. The chimney mouth is also protected by thick steel plates, leaving only a lateral row of mouths diagonally behind the chimney. If it weren't for Li Zhi's reminder, everyone wouldn't know that it was a chimney.

Hong Chengchou suddenly realized and said, "This is powered by a steam engine. ”

Li Zhi nodded and said, "Yes, this is our first-generation steam tank. ”

With a wave of his hand, Li Zhi said, "Su Laosan, you go up and operate it for me." ”

Su Lao sang loudly, opened the door of the chariot with the key, and went in with two of his men.

The people looked at the chariot with their eyes to see how it moved. After a while, puffs of smoke came out of the small chimney behind the chariot. I don't know if Su Laosan burned wood or coal in the chariot, in short, he burned the boiler of the steam engine.

Su Laosan shouted in the chariot, and the tank's body shook violently and began to move forward.

Under the stunned gaze of the officials, the heavy steam tank did not need to be pulled or pushed, and moved forward with its own power.

At first, the tank drove very slowly, as if it were climbing. But slowly, the tank drove faster and faster on the dirt ground, and had the speed of human walking.

The steam tank slowly drove towards the trench two miles away, leaving a few deep wheel marks behind it.

Li Zhi nodded, and secretly said that Su Laosan was worthy of being the one who made hundreds of locomotives, and he was also handy at making steam tanks.

With a wave of his hand, Li Zhi sent a group of soldiers into the trench in the distance, ready to fire.

When the Tianjin officials saw that the soldiers in the trench were really loading, they held their breath one by one, not daring to breathe loudly. They were afraid that the steam tank would not be able to withstand the fire of the infantry, and killed Su Laosan in the car.

"Bang Bang!"

The infantry in the trenches fired heavily at the steam tanks.

However, the bullet hit the hard steel plate but did not have the slightest effect, that is, it left a mark.

The soldiers in the trenches set up mortars and prepared to blow up the tanks with flowering shells.

Huan Yihua saw that the artillery in the trench was erected, his eyes widened, and he said, "Lord Wang, Su Laosan can be in the tank!" ”

Li Zhi smiled: "Don't worry, you can't blow up the tank." ”

"Bang bang bang!"

Five mortars fired at the tank at the same time, and the flowering shells landed on the side of the tank and exploded.

However, the shock wave blew up on the tank's armor and had no effect. Unaffected, the tank continued to drive forward.

The officials were shocked, and then they breathed a sigh of relief.

Huan Yihua praised: "Lord Wang! As soon as the steam tank comes out, the trench will have no effect! ”

Xie Liangyou sighed: "It's amazing, it's amazing!" ”

Hong Chengchou stroked his beard and praised: "Lord Wang, this tank is in hand, the trenches of the Jiangbei Army are useless!" ”

Su Laosan and the other soldiers in the trench stopped attacking him, jumped out of the tank through the side door, and ran to Li Zhi's side.

Li Zhi nodded and said, "Su Laosan, you made a good tank!" You ponder and ponder, improve while doing, and build 200 units within half a year. ”

Su Laosan said loudly: "Lord Wang, don't worry." ”
