The rock statue watched the 10 group drag its legs away without sorrow or joy. It was silent and stable as a dead dog.

However, it has no eyes.

That's just a feeling it gives.

Who is it?

Where does it come from?

Why does it exist?

I don't know.

Out of the hemispherical building, Bi Mingzhu found a new tool for Ning Tao, an alloy hammer with a hammer head of at least 20 or 30 kilograms.

Ning Tao took the hammer, swung it up and smashed it on the stone leg.

When!

Sparks splashed everywhere.

The place where the stone leg was hit appeared a little concave, but it returned to normal in a twinkling of an eye.

"My grass, I don't believe I can't smash you!" Stimulated, Ning Tao swung his hammer and greeted the stone leg again and again.

When!

Dangdang!

Dangdang!

Mars is full of craters, but the stone leg can be restored almost instantly. No matter how Ning Tao smashes it, it can repair itself and remain intact. Let alone being smashed flat and smashed, even a stone skin didn't fall off.

A meal is as fierce as a tiger and has no destructive effect.

Ning Tao threw the hammer on the ground and sat down on the stone leg.

But it was this sitting. Lao song was slightly stunned, then stretched out his hand to touch the ground, and retracted to touch the stone leg.

Bi Mingzhu said curiously, "old send, what are you doing?"

Ning Tao said, "Pearl, come and have a try."

Bi Mingzhu said with a smile, "I want to sit on your legs. The stone legs are hard. What's good to sit on?"

Ning Tao stretched out his hand and pulled her over: "just sit down and try."

Ningbi sat down next to Mingtao.

"Feel it." Ning Tao said.

Bi Mingzhu was slightly stunned: "how does it... Have temperature?"

"Yes, how can it have temperature?" Ning Tao said he didn't understand.

When dragging the stone leg out before, the sensory nerve of the palm was not complex, so the feeling was not obvious. But when the ass sits on the leg, some parts of the nerve are very developed and sensitive. I feel it all at once. The stone leg has temperature.

"Is it alive?" Bi Mingzhu said.

Ning Tao suddenly remembered something and said excitedly, "I can't break the rock statue with an axe, and I can't break the leg with a hammer. Maybe it's feasible to attack with fire!"

"Let's try. Anyway, you have firewood." Bi Mingzhu said.

As soon as he said he would do it, Ning Tao untied the firewood bundle on his back, handed over the cactus leaves sandwiched in the firewood bundle to bi Mingzhu, and then drilled a wood to make a fire.

A small bonfire burned, and the blazing light dissipated the darkness. But it's only part of the darkness. I don't know how big this underground base is. Until now, 10 combinations haven't seen the edge. Some of the illuminated places are dusty open spaces, some are stacked with rotten instruments and machines, and some weathered sundries.

Ning Tao didn't observe the surrounding environment carefully. He grabbed the soles of the stone legs, lifted them up, and baked the lower legs of the stone legs on the fire.

Soon, a black smoke rose from the stone leg, accompanied by a smell of burnt meat.

Ning Tao stared at the burning part, which showed signs of carbonization. Moreover, the burned place has not been restored.

"Useful!" Bi Mingzhu said excitedly, "Lao song, we can burn the stone man with fire. I'll go nearby to see if there's any oil, and then burn that guy!"

"Be careful and don't go far." Ning Tao gave a warning. He put the stone leg down, looked at the burned place by the light of the fire, and then fell into meditation.

It is obviously a stone, but it has the ability to regenerate. It is not afraid of knives and axes, but fire can scorch it. The stone man, and what is this leg made of, and who is it made of?

While he was thinking about this, the burnt place on the stone leg was slightly blue in the light of the fire. It feels like a sand grain reflecting blue light shining on the beach with a blue beam.

What's that?

Ning Tao was surprised. He squatted down and opened his eyes to look at the place with blue light, but it was too small to see what it was. He reached out to clean the scorched particles where the blue light reflected. He imagined it would be very difficult and might not even be able to pull them off. After all, he can't destroy it with an axe or a hammer. But this time, his fingers easily pulled down the burnt particles there.

Originally, it was just a reflective point the size of a grain of sand. After the surrounding charred particles were removed, its area became larger, but it was still buried deep in the lower leg. I don't know what it is. Ning Tao tried to pull a finger in, but his finger was too big to reach in at all.

He stood up, grabbed the ankle of the stone leg, lifted the stone leg up again and burned it on the campfire.

Black smoke billowed and the smell of burning the corpse became stronger and stronger. Before long, the lower leg of the stone leg was ignited and began to burn itself.

In the fire light, the blue reflection points are more and more, bigger and bigger.

Ning Tao stared at it, but he still couldn't see what it was.

Bi Mingzhu came over and didn't find any oil, but found a knife, one foot long, dark all over, reflecting the fire light, which looked very sharp.

"I didn't find any oil, but I found this knife. I tried it. A common metal knife can cut a hole. It's very sharp, so I brought it back and kept it for you." Bi Mingzhu handed the alloy knife to Ning Tao, but at this time she saw the blue thing in the ignited stone leg. Her sight was immediately attracted and said curiously, "what's that?"

"I don't know. I'll know when the skin is burned." Ning Tao took the knife from Bi Mingzhu's hand, then reached into the fire and scraped away the scorched particles covering the blue thing with the blade.

The scorched particles were scraped off, and the blade rubbed with the blue thing, and a blue spot immediately appeared under the blade.

As more charred particles were scraped off, a blue leg bone was exposed.

Ning Tao and Bi Mingzhu were stunned on the spot.

He always thought it was a stone leg, no flesh, no bones, just a carved leg. However, after the appearance of the blue leg bone, all this has changed, in a mysterious and unknown direction.

"Is it a robot?" Bi Mingzhu broke the silence between them.

Ning Tao said: "maybe the stone covering the leg bone is not a stone, but a material we don't know. It has strong protection and self-healing ability, and fire is its weakness."

So far, he has ended this thing.

The Bush and firewood brought in by Ning Tao from the canyon had been burned up long ago, but that leg was still burning. Without the green smoke produced by the burning of firewood, it is pure black smoke, and the smell of burnt meat is particularly obvious.

Ning Tao kept scraping off the particles left on the blue leg bones after burning, and the blue leg bones and soles of the feet appeared completely. Finally, when he was about to burn the last part of the end of his thigh, he stepped out the fire with his foot and retained the last "stone skin".

The alloy knife found by Bi Mingzhu played a role again. Ning Tao used the alloy knife to remove the scorched particles one by one, and the cross section of the stone skin was revealed.

It's not a rock. It's really an unprecedented material. It is divided into several layers. The first layer is a skin layer similar to rock, the second layer is a strip-shaped fiber layer, and the third layer is a reticular layer. It is like a mesh wrapped on a blue bone. At the same time, it also seems to act as a neural and vascular network.

Ning Tao has seen many robots and killed many, but this is the first time he has seen such a robot.

"It's really a robot. I've never seen such a robot. Who created it?" Bi Mingzhu was also surprised and confused.

Ning Tao just smiled bitterly. He also wanted to know the answer to this question.

He squatted down and reached out to touch the blue bone. The blue leg bone looks like crystal, but it has temperature and feels like a living bone.

Bi Mingzhu also squatted down and squatted opposite Ning Tao. She reached out and touched the blue leg bones. Her focused expression sent a signal to the opposite God of giving birth. She was also studying this.

However, Ning Tao's sight was attracted by her out of control, and then he couldn't move away.

In this serious and important moment, Lao song should not have been moved by the untimely.

"Old send, do you think there will be such a stone robot here?" Bi Mingzhu looked up at Ning Tao and asked, but found that Ning Tao was staring at her. She also looked at herself along Ning Tao's line of sight, and then tilted her mouth. "I'm talking to you. Be serious. Now is not the time to tell a story."

Ning Tao looked back this time and coughed awkwardly: "the situation we are facing now is very simple. If we want to study the machine, we must kill the stone robot guarding the machine. But we don't have oil. We can't use firewood, so our first task is to find oil."

"But I've searched all around us, but I haven't." Bi Mingzhu said.

Ning Tao said: "this is a big base. We can find axes, hammers, knives and oil. In addition, I think we should look in the direction we came."

"Do you mean to go under that apple tree?"

Ning Tao nodded: "the machine said that the woven virtual universe was sent to that direction. I doubt that the tree is the end. We should go and have a look, saying that we may not find it."

"Well, let's start now." Bi Mingzhu stood up.

Ning Tao grabbed the blue leg bone and stood up. After losing three layers of peripheral tissue, the weight of the leg bone decreased greatly, together with the remaining part of the "stone skin" at the end of the thigh. The weight is estimated to be between 20 kg, which is just used as a war hammer.

They set out again and walked in the direction of the apple tree.
