The beam of No. 250 green hat shone on a door, which was alloy and tightly closed.

Ning Tao and Bi Mingzhu looked at the tightly closed alloy door with the words "very unwelcome" written on it.

Bi Mingzhu took photos on the left and right sides, and the hemispherical building had no windows.

Ning Tao didn't want to go around the back to see if there were any windows. He raised his alloy axe and split it on the door.

Bang!

The alloy door shook and a crack appeared on the alloy door panel.

Although Lao song has no mana or super power, his physical strength is very powerful. After all, he is a frog leg Lao song, and his abdominal muscles are eight, which is quite awesome.

However, just as Ning Tao raised his axe again and was ready to chop down, the crack on the alloy door suddenly closed again. The door was as smooth as ever, leaving no trace of being cut.

Ning Tao was stunned on the spot, and his axe hovered in mid air and couldn't chop down.

Back then, his magic armor and divine armor also had such functions, but it was a virtual world after all, allowing the existence of special effects. Isn't this the real world? How can there be such special effects?

"Pearl, did you... Did you feel mana fluctuation just now?" After being stunned, Ning Tao asked.

Bi Mingzhu didn't seem so surprised. When Ning Tao was in a daze just now, she seemed to be thinking. Ning Tao's voice interrupted her thinking. She said after a delay of two seconds: "I didn't feel any magic fluctuation, but this door can also be started by bioelectricity."

"Ah?" Lao song is frightened again.

"You let me try." Bi Mingzhu put her hand on the alloy door.

There was a faint blue light on the silver alloy door, and then it opened automatically with a click. Not only was it turned on, but the lights inside the building were also on.

Behind the alloy door is a passage. You can't see the light, but there is a light that shines everything brightly.

"Pearl, are you so sure this door is opened with bioelectricity?" Ning Tao was filled with surprise and confusion.

Bi Mingzhu said: "because I found that the material of this door is the same as that of the activation button in this hat, and there is a slight electrostatic reaction when approaching. Also, this alloy should be the most advanced metal in the universe, smart alloy, which has the ability to heal. In the universe you dominate, haven't you studied this smart alloy?"

Ning Tao was embarrassed and changed the topic: "let's go in and have a look."

A master who is busy sending children, how can he have leisure to study what kind of wisdom alloy?

Bi Mingzhu followed Ning Tao into the door and said, "but this kind of smart alloy is very rare. In the universe I dominate, even the top scientific and technological civilization makes a suit of armor. Unexpectedly, it's a luxury to use it as a door."

Ning Tao suddenly remembered something: "Pearl, when you opened the door just now, you just used bioelectricity, didn't you enter a password or something?"

Bi Mingzhu said, "no, it doesn't need any password."

Ning Tao said thoughtfully, "the axe can't split, but you don't need a password. You only need bioelectricity to activate and turn it on, that is to say, as long as it's a person, you can turn it on, right?"

"Yes." Bi Mingzhu looked very sure, and then asked, "what do you want to say?"

Ning Tao said, "don't you think it's abnormal? We walked all the way to such a large base and didn't even find a body. Such an advanced door only needs bioelectricity to open."

"Yes, we haven't seen a body all the way. It's not normal for such a large base." Bi Mingzhu's reaction is slow, but there is no problem keeping up with the old idea.

In fact, not to mention a corpse, not even a suspected human or animal bone was found. There are cactus, medlar, shrubs and weeds in the canyon outside, but there are only tree roots and instruments here, and even tree roots are dead.

So here comes the question....

Who built this huge base?

Before Ning Tao came up with one, the end of the passage came.

That's another alloy door.

This time Ning Tao didn't wait for Bi Mingzhu to stretch out his hand, so he stretched out his hand and pasted it.

When he opened the door, he felt no blue light, but there was no blue light.

Behind the door is a closed space, in which there is a large machine and a rock statue. It is as high as a normal person and has no face, so it can't see what kind of statue it is. It lacks a leg, but it can still maintain a standing position.

Ning Tao walked towards the machine.

It's a very strange machine. It looks like an old and extremely complex textile machine.

Of course, it's just a feeling. It can't be a loom.

Without warning, Ning Tao suddenly remembered what Wu had said. He said that there was a machine on the rune space.

Ning Tao has been looking for the machine, but he can't find it. In the world where hundreds of millions of seeds fight and compete, he doesn't even see a screw, let alone a machine.

Now a machine appeared in front of him.

Along the way, he got up and saw a lot of machines and instruments, but they didn't stimulate the memories related to machines, but now they came out all at once.

"Lao song, the machine you said... Could it be this machine?" Bi Mingzhu also remembered the machine, but it was half a beat slow.

Ning Tao said, "I don't know. Let me try to activate it."

He went to the machine and reached out to touch it, but stopped just as he was about to touch it. His vision fell into the machine, and he saw a tree root. The characteristics of the tree root were the same as those given to him and bimingzhu.

Bi Mingzhu came to Ning Tao. She also saw the roots in the machine. Her eyes were full of surprise and confusion.

Ning Tao touched the machine with his hand.

The old and complex machine suddenly had a faint blue luster, and the parts inside turned slowly. In a moment, those parts similar to the loom woven a light curtain, in which there were faint images, but they could not be seen clearly.

Ning Tao opened his eyes and wanted to see clearly what was in the light curtain, but he still couldn't see clearly. He anxiously said, "Pearl, do you see anything?"

Bi Mingzhu shook her head: "there seems to be something in it, but it's very vague."

Click!

A strange voice came.

Ning Tao's first reaction was the sound of the moving parts in the machine, but he didn't feel like it. Then he was alert and his eyes moved to the side.

At that moment, a rock fist with a big bowl blew up.

The rock statue moved!

"Be careful!" Ning Tao roared and ducked.

The rock fist of the faceless rock statue wiped Ning Tao's scalp and waved it.

Ning Tao pushed the Bi Mingzhu away, and then hit the neck of the rock statue with an axe.

When!

The alloy axe struck the neck of the rock statue, and sparks splashed in the deafening sound.

But it was just a mass of Mars, and there was not even a cut mark on the neck of the rock statue.

The rock statue walked towards Ning Tao, but one leg was missing. The forward leaning body suddenly lost its balance and fell down with a dull sound on the ground.

Ning Tao hit the back of the head of the rock statue with an axe.

When!

Another burst of Mars.

The alloy axe rolled its edge, but the back of the head of the rock statue was still good, and even a piece of skin didn't fall down.

"It, how can it move?" Bi Mingzhu panic tunnel.

Without waiting for Ning Tao to return to the Bi Mingzhu, the rock statue suddenly stood up straight again and blasted another fist at Ning Tao.

It must have great power, but it is slow and lacks a leg. As soon as he got up, Ning Tao dodged, so his fist fell again.

Ning Tao stepped back and greeted Bi Mingzhu: "go quickly. If you are hit by it, you will die!"

Bi Mingzhu ran to the door.

The rock statue chased towards the door and fell to the ground in one step, but then stood up like a spring and continued to chase. Although this is the way, the speed is also OK, which is faster than the normal walking speed of ordinary people.

Although the speed of the rock statue was far less than that of the Bi Mingzhu, Ning Tao was still worried. When the rock statue stood up and continued to chase the Bi Mingzhu, he jumped up from the back and hit the back of the rock statue with an axe.

Sparks splashed everywhere.

The rolling edge of the alloy axe was more powerful, but the back of the head of the rock statue was still intact, not even a trace of being cut.

The rock statue was attacked, turned around and punched Ning Tao in the head.

Ning Tao jumped back and avoided easily.

The rock statue chased, fell to the ground, bounced up and finished at one go.

But at this time, Ning Tao has been several meters away from it. This is because he was worried that the rock statue went after the Bi Mingzhu again. He didn't hide far and deliberately kept a little distance from temptation.

"Old send, come out quickly!" Bi Mingzhu hurried to tunnel.

Ning Tao said, "I want to see what the machine will appear."

During his entanglement with the rock statue, the machine has been running, and there are more and more images in the woven blue light curtain.

But I still don't know. I can't see what is woven.

Dodging, Ning Tao has walked around the back of the machine.

He saw a leg carved out of a fallen rock. He grabbed the ankle of the stone leg and tried to drag it away. He lifted and dragged the stone leg. Although it was very heavy, it was also dragged by him.

The rock statue chased behind the machine.

"Lao song, what are you doing?" Bi Mingzhu anxiously tunnel.

Ning Tao said, "its legs are here. I want to take them away and study them."

Bi Mingzhu rushed in, jumped up and kicked on the back of the rock statue, and then somersaulted away one by one.

The rock statue turned again to chase the Bi Mingzhu.

"I'll distract it and you drag your legs out." Bi Mingzhu said while dodging.

"Be careful." Ning Tao dragged his stone legs to the door.
