Chapter 421 Steel Mansion

"Dog things, don't talk about martial arts!"

Seeing the giant sword thrown over, Zhang Tuohai was startled and hurriedly reversed the car. At the same time, Xiao Ai popped out 20 mechanical arms and shot the giant sword intensively with four 23mm cannons. .

Da da da.

The classified shells formed an insurmountable metal barrier in front of the infantry fighting vehicle, forcibly hitting the flying giant sword to one side.

With a muffled sound, the giant sword was inserted into the metal ground next to it, with a depth of one meter.

Seeing the appearance of the giant sword, Zhang Tuohai was secretly shocked.

The ground made of steel is more than one meter deep. If your car is solid, even the front armor may not be able to withstand it.

"These guys are really powerful, it seems that they have to deal with it more carefully."

Zhang Tuohai became more and more vigilant in his heart. He found that the guardians in this dungeon were extremely strong, and they really had the strength to kill him head-on. If he was not careful, he would really fall here.

Zhang Tuohai stayed in place for a while, glanced around vigilantly, and after confirming that there were no other guardians around to continue to attack, he breathed a sigh of relief, released the steam self-propelled machine, and searched for supplies.

Especially those two armors and their giant swords, which can block a blow from the 105mm main gun, are by no means ordinary metals, and they can definitely decompose some good things.

After dealing with these matters, Zhang Tuohai sent a private message to Su Mu: "Is there any background information on your treasure map? What is the origin of this steel manor? Isn't everything in it so powerful?"

"I don't know either, there is nothing written on the dungeon admission ticket." Su Mu said and photographed the front and back of the admission ticket to Zhang Tuohai, which did not contain any information.

"To be honest, in fact, I don't know as much about this place as you. The last time I came, I was blocked by the steel gate, and I didn't even come in."

Su Mu said helplessly.

Hearing Su Mu's words, Zhang Tuohai raised his eyebrows. Originally he thought that the gate was a means of blocking players, but now it seems that it is also a test to directly prevent players with insufficient strength from outside the gate. He rushed in and gave his life in vain.

However, it didn't help the situation in front of him.

Now, he is still at a loss here.

"Forget it, let's take one step at a time."

Zhang Tuohai was helpless, he kept 100 and led a group of steam machines to clean the battlefield here, while he continued to drive forward.

Bypassing the fountain, in front of you is a huge two-story mansion.

Similar to the mansion on the cover of a detective novel, just looking at it from a distance, it gives people a terrifying and gloomy feeling, exuding a rotten and mildew smell from the inside out.

What Zhang Tuohai cared about most was that this mansion was actually made of steel.

Also, there are no windows on it.

The positions of all the windows were sealed off by steel plates.

From a distance, it feels like a huge steel coffin.

"It looks a bit wicked here."

Zhang Tuohai looked at the door of the mansion and hesitated to enter.

After all, the matter of the fountain statue and the armor just now gave him a lingering fear.

"Why don't you just drive the car and rush in to take a look? However, the door is a bit narrow, and the car doesn't seem to be able to charge in."

Zhang Tuohai held his chin and looked at the steel gate of the mansion.

[There are 12 armor statues behind the gate of the mansion, waiting for your entry. 】

The prompt system slowly popped up a line of prompts.

"So insidious?" Zhang Tuohai almost scolded.

He would recognize this mansion if it were just a tortoise with a shriveled head, but if it was a tortoise and ambush him behind the door, it would be unbearable.

Thankfully he didn't go in, otherwise, even if he wore a steam-powered exoskeleton, I'm afraid he would be killed.

"Xiao Ai, prepare a rocket for me. I'm going to do it, but you dare to ambush me."

Zhang Tuohai said angrily.

"clear!"

Xiao Ai retreated the infantry chariot to the center of the courtyard.

"Sister, what is Brother Zhang doing?" Su Qi asked curiously.

"I don't know, it seems that the cannon is used to open the door. This door also looks solid." Su Mu said uncertainly.

However, she wasn't sure.

Although the gate is made of steel, it is too exaggerated to open it with artillery.

However, she soon found herself conservative, because two honeycomb rocket launchers actually popped out.

"Sister, isn't he going to blow up the mansion?" Su Qi asked in disbelief.

Before Su Mu could answer, the shrill sound of the rocket's launch confirmed her guess.

Whoosh whoosh!

Boom, boom, boom!

A series of rockets slammed into the door of the mansion.

The shards that blew the door flew.

However, what is shocking is that although the door of the mansion was blown into large pieces, there was still a thick steel plate inside. The rocket salvo just now failed to blow the door open.

Seeing this situation, Zhang Tuohai could not help but gasp.

This mansion is too solid, isn't it?

A gate can withstand a volley of rockets. Is this an apocalyptic bunker?

"Commander, do you want to conduct a second round of test firing?"

Xiao Ai was also a little unwilling. This was a rare setback for her attack. She immediately loaded her rockets and prepared to be ashamed of herself.

"No, isn't it sturdy, then just put it on the aerial bomb in one step, I don't believe its roof can be so strong!"

Zhang Tuohai said coldly.

"clear!"

Xiao Ai immediately started the newly remodeled helium balloon.

A khaki-colored, shark-head-painted helium balloon emerged from the infantry fighting vehicle and lifted the infantry fighting vehicle to a high altitude. The four propellers at the tail controlled Fang and slowly brought the infantry fighting vehicle to the mansion. hover above.

Several robotic arms took out the special aviation bomb made by the Red Fort from the cabin and aimed at the mansion.

"Ki, Kirov?!" Su Qi looked at the infantry chariot in the sky and covered her mouth in astonishment.

"Fire!"

Zhang Tuohai shouted.

Boom, boom!

A round of aerial bombs fell on the mansion.

Although the mansion made of steel is very sturdy, the aerial bomb thrown by Zhang Tuohai was specially made by the Red Fort. Jill used this thing to level a city directly, so a mansion in a mere area is no longer a problem.

Boom!

The explosions sounded one after another, and when the second round of bombs fell, the Iron Mansion began to collapse.

After the fourth round of aerial bombs, there will be no items higher than one meter in the entire mansion.

Zhang Tuohai looked down at the explosion site of the mansion and was very satisfied with his handwriting.

"Let 100 bring everyone up, clean up the rubble, dismantle everything that can be dismantled, and try to get the titanium alloy together."
