There is a term in sociology 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 make people go out easily.

For example, if a country is accustomed to purchasing advanced foreign weapons, when a neighboring country has more advanced weapons, the first thing it thinks about is to buy more advanced weapons, rather than develop them by themselves.

For example, it is better to buy a theory than a national government.

For example, the third brother next door.

After Zhang Tuohai got the benefit from breaking through the wall, now when he encounters the wall, he usually breaks directly, rather than bypassing it.

This factory uses a frame structure. Except for the main supporting steel frame, there is a layer of iron sheet outside, which looks like a plastic greenhouse.

The factory was full of various machines. Crowds of workers wearing blue overalls were busy on the production line, and noisy noises rang through the entire factory.

Zhang Tuohai glanced at him, his heart was startled, and then his face showed joy.

He discovered that this was actually a steam tank manufacturing plant.

Tracks, gun barrels, and armor plates are 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 and Limestone City are already mortal enemies, and there is a chance to weaken Limestone City's strength, he will naturally not let it go.

Da da da!

Zhang Tuohai's controller fired a few shots into the air with the steam machine gun.

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, hurry up!"

In order to increase the persuasiveness, Zhang Tuohai pulled the trigger at several steam tanks that were similarly assembled.

Da da da.

The bullet hit the rivet armor and was cremated.

"Run!"

The workers were dumbfounded, and then fled in all directions.

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

"Sure enough, this thing speaks hard."

Zhang Tuohai patted 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 has 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 facing the factory.

There are all from level 1 to level 3.

These are all materials used to make steam tanks.

However, it is now Zhang Tuohai.

In the corner of the factory, Zhang Tuohai saw a huge canvas, which seemed to be covering something.

Under 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?"

Under curiosity, Zhang Tuohai wandered around the box, and he found a small door at one end of the box.

Zhang Tuohai was curious and opened the door.

Inside the metal box are also various complicated mechanical transmission devices, as well as several things like mechanical arms, except that they are loaded with screwdrivers and pipe wrenches.

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

Perhaps the rotorcraft is more suitable.

This thing is like a chair with a propeller installed on it. There are some steam pipes and metal guards around the chair. The simplicity is horribly simple.

The only weapon is a steam machine gun.

It seems that the combat method is similar to that of the aircraft of World War I.

[You have found a level 4 auto parts dedicated to steam technology: a repair factory for the steam rotor aircraft. You need to open the grotesque technology tree to install, and the test meets the conditions. Do you want to install it?

[Steam rotor aircraft and its supporting repair factory: steam technology special grade 4 auto parts, the vehicle will have a steam-powered rotorcraft after loading, and the driving method is manual driving. Can be used for armed investigation. Stay in the air for 2 hours. After damage, it can be repaired in the repair factory. Armament: A steam machine gun, ordinary rivet baffle.

"Awesome!" Zhang Tuohai's eyes flashed brightly.

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

Greatly enriched his combat methods.

Adding a helicopter to the infantry fighting vehicle is exciting when you think about it.

"Install!" Zhang Tuohai said loudly.

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

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 there was no change in the rest.

"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 rotorcraft stopped there quietly, the cabin door and the lifting platform were all available.

Can take off at any time.

Zhang Tuohai happily touched the steam rotor plane, wishing to drive out and fly around now.

However, Xiao Ai interrupted his fantasy.

"Commander, infantry from the brigade appeared at the entrance of the factory, as well as the sound of steam tanks. It is estimated that the enemy will have 30 seconds to reach the battlefield."

"Use the grenade to contain the infantrymen, then find the abandoned intercity subway tunnel and leave here."

Zhang Tuohai ordered.

"clear!"

Boom, boom!

Two grenade shells were fired, blocking the infantry from the factory gate.

After the infantry had paid dozens of casualties, they hid behind the bunker, not daring to stand out, waiting for reinforcements from the steam tank.

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

The entrance is blocked by a brass gate, and there is a complicated mechanical lock that requires three keys to be inserted at the same time to open it.

However, Zhang Tuohai was not the kind of person who opened the door honestly. UU reading www.uukanshu.com

Now that the door is very strong, go around it.

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

Boom, boom!

With the sound of a few cannons, the brick wall next to the gate collapsed and shattered, revealing the dark intercity subway tunnel.

Because of the long-term abandonment, the inside was dark and a damp breath came out.

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

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

Zhao Wanwan then entered.

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