The rock statue watched as the 10 combinations dragged its legs away, not sad, joyful, silent, and as steady as a dead dog.

However, it does not have eyes.

That's just the feeling it gives people.

Who is it?

Where does it come from?

Why does it exist?

There is no way to know.

Out of the hemispherical building, Bi Mingzhu found a new tool for Ning Tao, an alloy hammer, the kind with a hammer head of at least twenty or thirty catties.

Ning Tao took the hammer and picked it up, slamming it on the stone leg.

While!

Sparks splash.

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

"I'm grass, I don't believe I can't smash you!" Ning Tao was stimulated, picked up the hammer and beckoned to the stone leg again and again.

While!

Dangdang!

Dangdang!

Mars are in a mess, pits are pitted, but the stone leg can be restored almost instantly, no matter how Ning Tao smashes it, it can repair itself and remain intact, not to mention being smashed flattened and smashed, not even a stone skin has fallen.

The operation is as fierce as a tiger, and the destructive effect is completely useless.

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

But it was this sitting, Lao Xiang was slightly stunned for a moment, then reached out and touched the ground, retracted back and touched the stone leg.

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

Ning Tao said: "Mingzhu, you can also sit and try." ”

Bi Mingzhu said with a smile: "I want to sit on your legs, the stone legs are hard, and what is good to sit on." ”

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

Bi Mingzhu sat down next to Ning Tao's side.

"You feel it. Ning Tao said.

Bi Mingzhu was slightly stunned: "It's ...... How can there be a temperature?"

"Yes, how can it have a temperature?" Ning Tao said, he couldn't figure it out.

When I dragged the stone leg out before, the sensory nerve in the palm of my hand was not complicated, so the feeling was not obvious. But the buttocks sit on the legs, and some parts of the nerves are very developed and sensitive, and I feel it all of a sudden, and the stone legs have a temperature.

"Is it alive?" said Billy.

Ning Tao suddenly remembered something, and said excitedly: "I can't smash that rock statue with an axe, and I can't smash this leg with a hammer, maybe it's feasible to attack with fire!"

"Then let's try, anyway, you bring firewood. Bi Mingzhu said.

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

A small bonfire burned, and the light of the fire dispelled the darkness. But it's only a part of the darkness, and I don't know how big this underground base is, and until now the 10 combinations have not seen the edge. The illuminated areas were dusty clearings, rotten instruments and machines, and weathered debris.

Ning Tao didn't pay close attention to the surrounding environment, he grabbed the sole of the stone leg and lifted it up, and put the lower leg part of the stone leg on the fire to roast.

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

Ning Tao stared straight at the part that was burned by the fire, and that part had already shown signs of carbonization. Moreover, the burned place has not been restored.

"It works!" Bi Mingzhu said excitedly: "Old send, we can burn that stone man to death with fire, I'll go nearby to see if there is oil or something, and then burn that guy to death!"

"Be careful, don't go far. Ning Tao admonished, he put the stone leg down, looked at the burned place by the light of the fire, and then fell into deep thought.

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

As he thought about this, the charred area on the stone leg glowed slightly blue in the light of the fire. It felt like a blue beam shining on the beach, with a grain of sand reflecting the blue light.

What's that?

Ning Tao was amazed in his heart, he squatted down, and looked at the blue light with wide eyes, but it was slightly raised, and he couldn't see what it was at all. He reached out to clean the burnt particles where the blue light was reflected, and he imagined it would be difficult, and possibly impossible to pick them off. After all, he can't destroy it with an axe or a hammer. But this time, his fingers easily picked out the charred particles in the area.

Originally, it was just a reflective spot the size of a grain of sand, but after the burnt particles around it were removed, it became larger, but it was still buried deep in the calf, and I don't know what it was. Ning Tao tried to put a finger in and pick it, but the finger was too big to reach in at all.

He stood up, grabbed Stoneleg by the ankle, lifted Stoneleg up again, and burned it on the campfire.

Black smoke billowed and the stench of burning the corpses grew stronger and stronger, and it wasn't long before the calf of the stone leg was ignited and began to burn itself.

In the firelight, the blue reflective points became more and more numerous and larger.

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

Bi Mingzhu walked over and didn't find any oil, but found a knife, more than a foot long, pitch black, reflecting the firelight, and it looked very sharp.

"I didn't find any oil, but I found this knife, I tried, ordinary metal can cut a hole with a knife, it's very sharp, so I brought it back, I'll give it to 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 eyes were immediately attracted, and she said curiously: "What is 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, scraping off the charred particles that covered the blue thing with the blade.

The charred particles were scraped off, and the blade rubbed against the blue thing, and a blue spot of light suddenly 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 had always thought it was a stone leg, no flesh, no bones, just a carved leg. However, after the appearance of this blue leg bone, all this changed, in a mysterious and unknown direction.

"Could it be a robot?" said Pearl, breaking the silence between the two.

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

So far, he's put an end to this thing.

The bushes and firewood that Ning Tao brought in from the canyon had already been burned, but the 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 that remained on the blue leg bones after burning, and the blue leg bones and soles of the feet were completely revealed. Finally, just as he was about to burn off the last part of the end of his thigh, he stomped on the fire with his foot, leaving the last bit of "stone skin".

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

It wasn't a rock, it was really a never-before-seen material. It is divided into several layers, the first is a rock-like epidermis, the second is a strip-like fibrous layer, and the third is a reticulated layer, which is like a mesh wrapped around blue bones and seems to function as a network of nerves and blood vessels.

Ning Tao has seen a lot of robots, and he has killed a lot, but this is the first time he has seen such a thing in front of him.

"It's really a robot, I've never seen a robot like this, who created it?" Bi Mingzhu's heart was also surprised and confused.

Ning Tao just smiled bitterly, and he also wanted to know the answer to this question.

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

Bi Mingzhu also squatted down, squatting opposite Ning Tao, reaching out to touch the blue leg bone, and her focused expression sent a signal to the goddess of sending children on the opposite side, she was also studying this.

However, Ning Tao's gaze was uncontrollably attracted to her, and then he couldn't take it off.

At this serious and important moment, Lao Xiang was very undeservedly untimely moved.

"Lao send, do you think there will be this kind of stone robot here?" Bi Mingzhu looked up at Ning Tao and asked, but found that Ning Tao was staring at her, she also glanced at herself along Ning Tao's line of sight, and then curled the corners of her mouth, "I'll talk to you, you are serious, now is not the time to tell stories." ”

Ning Tao retracted his gaze this time and coughed embarrassedly: "The situation we are facing now is very simple, we have to study that machine, then we must kill the stone robot that guards the machine." But we don't have oil, and we definitely can't use firewood, so our first task is to find oil. ”

"But I've searched all around us, and no. Bi Mingzhu said.

Ning Tao said: "This is a big base, we can find axes and hammers, as well as knives, and we can definitely find oil." Also, I think we should look in the direction we came. ”

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

Ning Tao nodded: "The machine said that the woven virtual universe was sent in that direction, I suspect that the tree is the end, we should go and see it, and it may not be found." ”

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

Ning Tao grabbed the blue leg bone and stood up, the weight of the leg bone was greatly reduced after losing three layers of peripheral tissue, and the remaining part of the "stone skin" at the end of the thigh was estimated to weigh between twenty catties, which happened to be used as a war hammer.

The two set off again, heading in the direction of the apple tree.
