Chapter 260 Steam Helicopter

Sociology has a term called path dependence.

It probably means that once people make a certain choice, the force of inertia will make this choice constantly self-reinforcing, and it will not let people go out easily.

For example, if a country is accustomed to purchasing foreign advanced weapons, when a neighboring country has more advanced weapons, it will first think of purchasing more advanced weapons, rather than developing them.

For example, what the government makes is worse than buying the theory.

Like the third brother next door.

After Zhang Tuohai got the benefit of breaking the wall, now when he encounters the wall, he usually breaks it directly instead of bypassing it.

The factory adopts a frame structure, except for the main supporting steel frame, the outside is a layer of iron, which looks like a plastic greenhouse.

The factory is full of various machines, and groups of workers in blue overalls are busy on the production line, and the loud noise resounds throughout the factory.

Zhang Tuohai glanced at him, startled in his heart, and then a look of joy appeared on his face.

He found that this was actually a steam tank manufacturing factory.

Tracks, gun barrels, and armor plates were removed from the production line and assembled into steam tanks.

"If you kill this place, the strength of Limestone City will definitely drop a lot!"

Anyway, he is now in a deadly relationship with Limestone City, and he will naturally not let it go if there is an opportunity to weaken the strength of Limestone City.

Da da da!

Zhang Tuohai's steam machine gun fired several shots into the air.

The workers raised their heads blankly and looked at the intruder in astonishment.

"I announce that this place has been taken over. If you don't want to die, get out of here!"

In order to increase his persuasion, Zhang Tuohai pulled the trigger on several assembled steam tanks.

Da da da.

Bullets hit the rivet armor, and the cremation splattered.

"Run!"

The workers froze for a moment, then ran away.

In less than half a minute, the entire factory became empty.

"Sure enough, this thing is still tough."

Zhang Tuohai clapped the steam machine gun beside him, and then led Xiao Ai to throw anti-tank grenades around.

Blow up all the machines that can be blown up, and throw a shot into the installed steam tank. Anyway, what Zhang Tuohai wants to do is to destroy the production capacity of the factory in the shortest possible time.

In addition to these machines, there are mountains of metal ingots and metal parts in the factory.

All from level 1 to level 3.

These are the materials used to make steam tanks.

However, now it belongs to Zhang Tuohai.

In the corner of the factory, Zhang Tuohai saw a huge canvas that seemed to cover something.

Out of curiosity, Zhang Tuohai tore off the canvas.

Below the canvas is a metal box. This metal box is very huge, about 8 meters long, 6 meters wide, and 4 meters high. From the outside, you can see all kinds of complicated gears hanging outside the metal box.

"what's this?"

Out of curiosity, Zhang Tuohai walked around the box and found a small door at one end of the box.

Zhang Tuohai opened the door out of curiosity.

Inside the metal box are also various complex mechanical transmission devices, as well as a few things like mechanical arms, but they are all screwdrivers, pipe wrenches and the like.

What surprised Zhang Tuohai the most was that there was a helicopter inside the metal box!

Perhaps a rotorcraft would be more appropriate.

This thing is like a chair with a propeller on it, and there are steam pipes and metal guards around the chair. The simplicity is astounding.

The only weapon is a steam machine gun.

It seems that the way of fighting is similar to the aircraft of World War I.

[You have found Level 4 auto parts for steam technology: a repair factory for steam rotorcraft. You need to open the Weird Technology Tree to install it. The test meets the conditions. Do you want to install it? 】

[Steam rotorcraft is extremely supporting repair factory: steam technology special 4th-level auto parts, after loading, the vehicle will have a steam-powered rotorcraft (helicopter), and the driving method is manual driving. Can be used for armed reconnaissance. Hang time is 2 hours. Damaged can be repaired in the repair shop. Armament: One steam machine gun, ordinary rivet baffle. 】

"Amazing!" Zhang Tuohai's eyes lit up.

With this thing, he has air power, which is very useful for both reconnaissance and attack.

It greatly enriched his fighting style.

Adding a helicopter to the chariot is exciting.

"Install!" Zhang Tuohai said loudly.

A white light enveloped the metal box and Zhang Tuohai's infantry chariot.

After a while, the white light dissipated and the metal box disappeared. Zhang Tuohai felt that the infantry fighting vehicle seemed to be slightly stretched by about half a meter, and the rest remained unchanged.

"This thing also uses space expansion technology?"

Zhang Tuohai flipped into the car and found that the steam rotor counterattack and supporting factories had been installed at the rear of the infantry fighting vehicle, separated by a metal door.

Open the metal door, the steam rotor plane parked there quietly, the hatch and the lift platform are all available.

Take off anytime.

Zhang Tuohai touched the steam rotor plane with joy, and wished he could go out and fly in a circle now.

However, Xiao Ai interrupted his fantasy.

"Commander, there is a brigade of infantry at the gate of the factory, and the sound of steam tanks. It is expected that the enemy will reach the battlefield in 30 seconds."

"Retain those infantry with grenades, then find the abandoned intercity subway tunnel and get out of here."

Zhang Tuohai ordered.

"clear!"

Boom, boom!

Two grenade grenades were fired, keeping the infantry out of the factory gate.

After paying dozens of casualties, those infantrymen hid behind the bunkers, daring not to come forward, waiting for reinforcements from steam tanks.

Subsequently, Zhang Tuohai found the entrance of the intercity subway tunnel under the prompt of the prompt system.

The entrance is sealed off by a brass gate and a complex mechanical lock that requires three keys to be inserted at the same time to open.

However, Zhang Tuohai was not the kind of person who honestly opened the door.

Since the door is strong, it's better to bypass it.

Zhang Tuohai took a few steps away, and then aimed the 75 gun at the wall next to the gate.

Boom, boom!

With a few cannon shots, the brick wall next to the gate collapsed and shattered, revealing the dark intercity subway tunnel.

Due to the long-term abandonment, it was pitch black inside, and a damp breath came out.

"That's it, let's go!"

Zhang Tuohai turned on his headlights and rushed into the tunnel first.

Zhao Wanwan then entered.

After entering, Zhao Wanwan retreated and made a simple booby trap with an anti-tank grenade at the door, before chasing Zhang Tuohai.
