Thanks to the reward of the law -

After borrowing Tianhuo's radar and conducting a detailed scan of the ruins of the hemispherical body, Wu Chen found that half of it was still buried under the ruins. In other words, it's a complete sphere. Although the outer layer of cement mortar has weathered and fallen off due to age, it is only a few meters deep. Further down, there is a dense layer of gravel.

These seemingly ordinary gravel are the associated minerals of the earth's rare transition elements (i.e., chemical elements from group III.B to group VIII in the periodic table), and are resistant to corrosion and high temperatures. Further down there is a high-strength alloy, and then there is a layer of dense polymer material......

With such layers of protection, this sphere, which looks like a big cement lump, looks very unusual.

Most importantly, as the outer protective layer was destroyed, stronger energy fluctuations began to emanate from the depths of the sphere.

"Master, I've scanned the entire structure, and it's likely that this sphere is made up of multiple concentric spheres nested in layers. And the material of each layer is different, and obviously they all do different things. Master, I believe that this sphere must be able to open. "The T160 is trying to break it down in a variety of ways.

Wu Chen had an idea, "You said it's a concentric sphere?" ”

"That's right." T160 replied with certainty.

"I understand...... Wu Chen walked back and forth along the huge sphere, looked up at the ruins above his head, and found a relatively flat ball to exert his strength.

Click! Tianhuo's palm sank into the spherical shell with a thud, crushing large swaths of concrete.

"Isn't that right?" Wu Chen thought about it and found a suitable place again. Gently press the spherical shell with both palms. This time counterclockwise.

The concrete under the palm of his hand is still crumbling in large pieces. But this time he clearly felt the loosening of the spherical shell! The brain waves gradually increased, and the dim Tianhuo eyes suddenly lit up with blue light! Wu Chen, who was incarnated as a transformer, rose up with all his strength and finally pushed the spherical shell! As if the super-large globe was reversed, layers of nested concentric spheres rotated in rings, and finally, under Wu Chen's legs, a triangular entrance was revealed!

"Master!" The T160 was the first to be discovered.

The light eye of the heavenly fire slowly extinguished. Wu Chen cut off the spiritual resonance with the MT mecha.

Wu Chen was right, there was an opening in each layer of the concentric sphere, but they were not together. Only by rotating the tongguò, stacking all the openings on top of each other, can you open the entrance to the core.

The entrance to the triangle can only accommodate the size of a human.

Wu Chen and Flicker got out of the mecha and walked towards the entrance side by side.

In front of the entrance of the triangle, there is a dense film of energy. Wu Chen tried to reach out and gently press it on the energy membrane.

Soon, with layers of surging blue light. Wu Chen's palm successfully passed through the membrane structure and entered the inside of the sphere. The flickering is also attached to the palm of the hand. The membrane structure suddenly lit up red!

"Be careful!" Before Wu Chen's words fell, a slowly expanding purple-red portal successfully forced back the red membrane structure. It seems that this energy membrane has the ability to screen genes, and only ordinary humans are allowed to pass through guò. So Flicker opened the door and passed himself in

"Master, this layer of energy film is very advanced, I want to study it." It was the T160 that spoke.

"Okay." Signaling to be careful, Wu Chen turned around and walked into the depths.

The long triangular corridor is hundreds of meters long. How many layers of spheres are nested together, Wu Chen did not count them in detail. That's a lot anyway.

At the end of the corridor is a wall that makes it impossible to tell what kind of material it is. Flickering opened a portal again, but never thought that it would collapse before it could be deployed.

"Gravitational field." T160 analyzed the energy source and gave the answer: "The distorted space-time does not provide smooth conditions for the portal to open. ”

"Are you saying there's a twisted plane behind this door, or is there something weird about this door?"

"Master, it's this door that's weird." T160 hurriedly explained.

"Master, I analyzed the structure of the door that opened the door at the moment when it flickered open. The matter that makes up this door is found to be the 'fifth state'. That is, ultra-solid, also known as super-dense state. When matter is at a pressure of 1.4 million atmospheres, the atoms of matter can be 'crushed'. All the electrons are 'squeezed' out of the atoms to form an electron gas, and the bare nuclei are closely arranged, and the matter is extremely dense, which is called a super-solid. A piece of ultra-solid material the size of a ping-pong ball, the mass of which is at least 1,000 tons. So, the mass of this spherical shell at the end is quite enormous. The gravitational field created by the great mass distorts space-time. ”

"With such a huge mass, why hasn't the fragile concrete surface of the spherical shell been crushed?" Wu Chen asked rhetorically.

"There is a mysterious antimatter shell in the sphere, which hedges out the extruded gravitational field, causing the huge gravitational mass to release its effects inward." The T160 was quick to give a reasonable explanation.

"I'll go!" Wu Chen sighed, "The pre-apocalyptic human technology has reached this point......

"T160, how do we get in?" Flicker asked.

"Since we can hedge the exerted gravitational field, in other words, according to Newton's third law, we can artificially control zhì to produce a certain angle between the two force arms......"

In T160, Wu Chen understood Newton's third law: the force and reaction force between two interacting objects are always equal in magnitude and opposite directions, acting on the same straight line.

"Master, there it is!" The T160 quickly gave a solution: "Master, just move the spherical shell in a specific direction, let the force of the antimatter shell and the supersolid material shell create an angle, and tear this door apart with the oblique component force generated!" ”

Wu Chen somewhat understood.

"Where are you going?"

"I'm calculating......" the T160 quickly calculated.

Wu Chen, who had nothing to do, began to look around curiously. The shells of various colors and materials are interlocking and superimposed into a tight spherical shell, and the closer to the core area, the finer the layers. The gaps between the layers are becoming more and more inseparable. "Huh?" Following the straight top corner line of the triangular passage, looking all the way, Wu Chen was close to the door. A small piece of excess debris was found. Inevitably, a bump appears in the straight line.

That feeling. It's like when the decorator is in the ceiling. I accidentally shook off the sawdust and stuck to it. This is an inevitable small flaw in artificiality.

Wu Chen tried to pick and found that he seemed to be able to move. So I picked it hard, and the small flaw suddenly shifted.

Hum -

Terrifying gravitational waves poured out overhead and slammed straight into the walls!

And this gravitational wave did not spread out in all directions, but was bound into a tiny line! Wu Chen and Flicker were spared because of the angle and height difference!

And the gate behind the two of them collapsed!

The core area that is being guarded to the death is revealed!

Wu Chen, who had palpitations, thought about it for a while, and finally sighed in admiration: "It turns out that the method of opening the door is not calculated. ”

The T160 has also finally discovered the calculation equation that is stuck in an infinite endless loop. You will never get an answer.

When he walked into the door, Wu Chen couldn't help but comfort the T160: "It's not your ability, it's the difference in your way." It boils down to the difference between humans and the intelligent brain. ”

"Why?" The T160 still hasn't figured it out.

"The person who designed this gate is human, so he is also testing human. Only human beings who are 'always striving for perfection' will subconsciously want to pick out that superfluous little flaw. And all the brains or machines have the same thinking as you, trying to open this door with the method of calculation. So, the result must be an infinite loop. ”

"I see......" the T160 shut up convincingly.

The energy supply in the core area is still continuing, so the items and furnishings inside are still the same as they were hundreds of years ago, when they were closed. It's the same as the energy film at the entrance. The core area is also wrapped in a more brilliant and high-tech energy film. It is like a huge disco glittering ball, slowly rotating with colorful streamers from time to time.

When Wu Chen repeats his old tricks. When the palm of the hand is gently attached to the membrane structure, this honeycomb-like membrane structure immediately becomes a screen in the swinging streamer.

The image flashed several times before finally appearing.

"Welcome, future human." A virtual figure in a white research uniform opened his mouth with a sad face.

Wu Chen tried to tilt his head, and after finding that the eyes of the virtual portrait also moved with him, he said, "What can I do for you?" ”

The virtual portrait finally showed a faint smile: "Yes, future people." There are many, many things we need from you......"

When the energy membrane opened to him, Wu Chen recalled a classic movie scene in a trance.

The dense cryogenic storage cabinets resemble the scene inside the Titan spacecraft launched by humans in Frozen Planet. Although it is still far from the ability of the Titan ship that can create a new Earth, the items stored in these cryogenic storage cabinets are all the same.

Gene.

A complete planetary gene pool.

"No, Future Man, I'm the 9th gene pool. The genomes of all animals under the phylum Chordates are stored. You'll have to find the remaining 8 gene pools to piece together a complete system of life on Earth. ”

"It's a complicated collection task." Wu Chen sighed, "Is there a hint?" ”

"I will help you as much as I can, but ......" said the virtual avatar staring at Wu Chen's eyes with a gaze full of hope: "Future people, are you sure you want to accept this mission to save the earth?" ”

"20150326-Y player, please make your choice carefully." Zero Coldness jumped out again.

"Can I talk to someone?" Wu Chen smiled at the virtual person.

The avatar gradually frowned. The expression of extreme disappointment that all the beauty revealed between his eyebrows was shattered by Wu Chen's ambiguity, obviously saying: No, can, to!

The old lady has been waiting for hundreds of years, how can I wait for you to be like you! Do you still have to think about the super-righteous proposition of saving mankind?

"Okay, I'll accept it, but ......" Before Wu Chen's patch was applied, a cold light shot straight into his forehead.

"I—" Before the word 'go' could be spoken, the whole person flew upside down and flew out of the gate and fell heavily to the ground.

By the time he looked up, the entrance was completely closed.

Touching the hot forehead, Wu Chen was about to scold, but the sphere had begun to turn!

Seeing the triangular passage gradually shift, the flickering finally appeared. A portal is in your hand to easily move the two out of the sphere.

Looking back, the spherical shell has returned to its original appearance. (To be continued......)
