Chapter 419

"I'm fine. Let's go and have a look at that copy?" Zhang Tuohai asked, stopping his car next to the beetle.

Compared with the tall and powerful infantry chariot, the originally Petite beetle is smaller, just like a children's toy.

"OK, I'll start the drawing now and prepare it over there."

Su Mu took out the drawing.

[player Su Mu invites you to enter the secret steel Castle together. Do you want to enter?]

"OK."

White light enveloped Zhang Tuohai.

After the white light dissipated, Zhang Tuohai found that the scenery around him had changed greatly and his car stopped in front of a huge steel gate.

The steel gate has a height of eight meters and a width of more than six meters. It is obviously a behemoth.

The walls on both sides are up to 10 meters high, with strong towers and sentry towers above.

Just looking like this, it's very oppressive.

It was just that the silence around him was heinous, and there was not even a trace of wind, which made Zhang Tuohai feel as if he had entered a dead world.

"Doesn't the world even have insects? Why is it so quiet?"

Zhang Tuohai is suspicious.

Soon, however, he threw the idea aside.

He came to search the secret place, not to study ecology. He didn't care about the ecology in the secret place.

"It's this gate. I've tried many methods, but they're useless. Even explosives don't have a good effect."

Su Mu said and pointed to the gate.

Zhang Tuohai found that there was indeed a black mark on the gate, which was obviously left after the explosion.

However, the effect is obviously not good.

"001, take someone to try the water."

Zhang Tuohai opened the rear door of the car. More than a dozen steam self-propelled machines came to the door, raised the electric saw and began to cut the steel door.

Zi - hum——

The electric saw fell on the steel gate, making a harsh sound, and a large amount of sparks splashed everywhere.

However, the chainsaw went deep into the steel gate.

"Effective!"

Seeing this situation, Su Mu's hanging heart was half relieved.

In fact, she came to Zhang Tuohai with the idea of trying.

If Zhang Tuohai can't do it, this copy will be lost to her.

The number of invitation tickets for each copy is not unlimited.

The one in her hand has only two chances. If she can't succeed this time, she can't enter this copy again.

Fortunately, Zhang Tuohai gave her more awesome power and gave her hope for success.

"Dice goddess bless, hope there can be something in it." Su Mu folded his hands and muttered to himself.

The steam powered machinery moved quickly, and the electric saw soon disappeared into the city gate.

Then, they found an embarrassing problem, that is, the gate is too thick, and the electric saw can't break through at all. There is a problem, that is, there is no way to open a hole in the gate.

"What should I do?" Su Mu didn't expect such a problem.

The gate is so thick that even the electric saw can't detect the thickness. What can I do?

"Use the conical method to dig in bit by bit. I want to see what's behind the gate. It's incredibly protected by such a thick gate."

Zhang Tuohai thought for a moment and said.

001 Wen Yan immediately changed the direction of the electric saw, inserted it obliquely into the gate, drew a cone on the gate, then expanded it circle by circle, and finally inserted the electric saw into the gate again. This time, he finally broke through the gate.

Zhang Tuohai came over and measured it. The thickness of the whole gate exceeded 1.5 meters.

"Who designed this? It's so thick? Did you take down the armor of the battleship?"

Zhang Tuohai was speechless.

The one meter five steel gate and the armor belt of ordinary battleships are not so thick.

What is in here that needs such a thick gate to protect?

Doubts rose in Zhang Tuohai's heart.

But anyway, since you have come here, open the door first, and then you can't go back empty handed.

Now that the gate was pierced, the rest of the work was much easier. Several steam self-propelled machines followed suit and made several big holes in the gate.

In order to increase the working speed, Zhang Tuohai sent 20 steam self-propelled machines to help. Soon, a whole gate was removed.

The efficiency of those steam self-propelled machines is very fast. The cut gate is directly decomposed into metal ingots and metal parts, which are neatly placed aside.

Suddenly, Zhang Tuohai found that a shiny metal ingot was placed next to a pile of level 3 metal ingots.

"What is this? Why is it left here alone?"

Zhang Tuohai came forward and picked up the metal ingot.

[titanium alloy ingot: special construction material.]

"This thing is titanium alloy?" Zhang Tuohai's face showed a happy look.

He is worried about this thing. It takes 200 units to build titanium armor. He has no way. Unexpectedly, he got one here.

"Where did you find this?" Zhang Tuohai asked excitedly.

001 pointed to the position of the metal gate, indicating that the metal ingot was disassembled from the metal gate.

"And such a good thing!"

At this time, Zhang Tuohai looked at the position of the metal gate as if he were looking at a huge treasure.

Although the metal gate has been dismantled, the city tower is still there, and the city wall is also there.

Since titanium alloy can be disassembled from the gate, can the city tower and city wall also be disassembled?

Zhang Tuohai was very excited: "001, send you a task to dismantle the city tower and city wall immediately with steam self-propelled machinery, and give priority to picking up special metal ingots, especially this one, you know?"

Zhang Tuohai shook the titanium alloy ingot in front of 001 and said solemnly.

Zi Zi——

001 nodded and began to dismantle the city building with many steam self-propelled machines.

"You, what are you doing?"

Su Mu asked puzzled.

"If you find something useful, let them look for it again. Let's continue to walk inside. It's not easy to come in once. We must take away all the benefits we can get."

Zhang Tuohai said, taking the lead in driving the infantry chariot towards the gate.

Seeing this, Su Mu glanced at the busy steam self-propelled machinery and hurriedly drove up.

Inside the gate is an ancient manor. The entrance is a huge courtyard. The ground of the courtyard is also made of metal. Huge metal ingots replace square bricks. In the center of the courtyard is a fountain. A metal Mermaid statue stands in the center of the fountain holding a water tank, and water pouring out of the tank.

What makes Zhang Tuohai most is that the hair of this Mermaid statue is all poisonous snakes.

Those poisonous snakes looked ferocious and all stared at him fiercely.

Seeing the statue, Zhang Tuohai felt a chill for no reason.

Suddenly, he felt something wrong.

He looked up fiercely and was surprised to find that the eyes of those poisonous snakes were shining in color.
