Chapter 730:

Li Huai and his father were panting and exhausted, and hours of climbing caused him to eat lunch among the rocks near the top of the mountain, which was covered by rocks. Then they once again carried their backpacks and trudged forward. In the end, they reached the sight on the other side, spreading a clear vision in front of them, clearly seeing the small valley below.
When they looked down, the air seemed to vibrate slightly. Li Badi rubbed his eyes. "It hurts," he said.
Father raised his eyes. "There is a strong vibration effect. This can be very dangerous because of the invisible rays of the sun and the concentration of light."
Once adjusted to the strange visual effects, like staring at the distorted heat rays from an overheated oven, he saw a small flat area in the mountains. In the center of this valley is some kind of large black structure. The distortion of the surrounding light makes it impossible to distinguish more information.
"That's it," Li Hao said. Father nodded, moved the backpack to relax his shoulders, unfastened the shotgun on his back, and carefully checked the load of the backpack.
Seeing what his father was doing, he suddenly realized the danger. How is it possible to do such a thing? What else is there besides the earth? Faraway space, things beyond the scope of human science, and unfriendly. Now, Li Huai realizes for the first time that he has no spare time-this is the enemy he and his father face-the enemy of all mankind-completely unknown.
He swallowed, held the rifle, and followed his father along the sliding rocky path.
As they approached the foot of the mountain, the strange shaking effect became more obvious. Avoid looking straight ahead and focus on the ground in front of his feet. Despite this, he can't help but notice that the surrounding stones seem to be gleaming in the invisible waves. From the bottom of the valley, the sky now seems to be covered with black and gray rings, as if they are reaching the center of some atmospheric vortex. After several hours of hard work, they crossed the barren rocky plain from the mountain.
Before them rose a huge circular structure, several stories high, ominously black, without any signs of doors or windows. Two huge projections protrude above the building, which ends in a huge shiny disc. One huge cup-shaped disk is facing the sun, and the other is pointing in the opposite direction.
As the two people get closer, the strangeness in the air increases. They felt that they were pierced by an invisible spear and pierced into the tiny Tottenham. "Radiation?" asked Bull softly, afraid of the answer. His father trudged hard for a while, then put down his backpack. He took out the Geiger counter and activated it.
He shook his head. He said: "There is no radioactivity." "Whatever it is, it's not like that."
They reached the wall of the building. Strangely, they seem to avoid the abnormal vibration here. Realizing that the source is above them, it may be that two powerful discs are raised high in the air.
Dennings investigated the building, but found no entrance. It must go around the wall a quarter of a mile, but there are no signs of doors or entrances. This wall is a rock-like substance, but it is like any rock or plastic that has never been seen before.
"We must enter," said Li Huai when they returned to the starting point, "but how?"
The father smiled. "This way." He opened the package and took out two cans of explosives. "I think these will come in handy. Fortunately, there are still some left from the blasting we conducted last week."
He placed the two jars at the bottom of the high wall, connected them together, and then pulled the wires to the farthest. When the two people were a safe distance apart, Mark ignited the explosive.
There was a thunderous roar: stones and dirt were sprinkled around them, and there was a little black powder. After the smoke cleared, Li Huai and his father jumped up, holding rifles in their hands.
There was a crack on the side of the wall where the explosive fell off. The crack is big enough to pass!
They rushed to the ground without saying a word, still smoking from the concussion, passing through the mysterious walls of the mysterious building.
The walls are thin, thin but hard, just like the masters of atomic engineering. Inside, they found a roomless building-a separate room within the frame of the outer wall.
The curved ceiling emits dim blue light. There are many huge machines on the uncleaned rocky ground of the building.
They are a spherical glass-like invention, many times the height of a person, connected by a string of thick metal rods and rows of smaller globes, but no one is familiar with them. The humming sound was steady, and the two giant metal masts that penetrated the ceiling slowly rotated. There is no doubt that the tops of these masts are affixed with huge sun-burning discs.
Can't see any creatures.
Li Huai and his father stood quietly, squatting, with rifles ready, but there was nothing to challenge them. Only the solar transmitter buzzed.
Shouted, but there was no answer. They moved forward cautiously, worried about being trapped. This place does not have a vibrant appearance. "An automatic station," Mark said, panting. "I think it's completely automatic."
Mark gradually proved right. Everything is automatic. Whoever built this structure to divert the sun’s rays, just put it down, move and leave. There is no evidence that the garrison or commander has any regulations.
They studied the machine, but found nothing. They found something that looked like a controller, but even though they pushed and pulled the lever and knob, the hum did not stop. The control appears to be a dummy, or must be specifically motivated.
"What are we doing now?" asked, they tried to pull all the joysticks on a particular switchboard without any results. "Do you still have enough powder to blow up the machine?"
Father shook his head. "I only have those two cans. We can try to shoot at the machine." He leveled the rifle and fired at the glass ball perched on the central sphere. The bullet hit it, and they saw that it didn't even dent the shiny surface.
"It won't work," Elder Denning said, producing the same effect after more hits, and the concussion echoing from the enclosed wall almost deafened them.
They continued to search for clues, but did not find them. Depressed Li Bai kicked a loose cobblestone and watched it rattle on a column near the main control board. A small metal ball was placed on the top of the column, obviously not fixed. He thought he was a replacement part and hovered on it. It's about his head level.
Thinking that if he checked it, he might learn the nature of some working machines, so he reached out with both hands to pick it up.
When his hand touched the metal ball, a terrible flash suddenly appeared. He felt grasped by uncontrollable forces, paralyzed instantly like a person who had paralyzed a live wire. He opened his mouth and screamed in pain, but he said nothing. Huge power surged in his body, radiating every cell and atom in him. He felt as if he had lifted from the floor. Then the earth seemed to dissolve in his hands. It turned into a dazzling light, became hazy, and then disappeared.
He stood there on tiptoes for a while, moved by the powerful violence, glowing with energy from the inside, and then he felt the supercharger dissolving, sliding into him, sliding into the ground, and then disappearing.
He stood in front of the pillar, swaying, but still active. His hands are still raised, but there is no ball of metal and strength between them.
He let them fall beside him and took a step. He is healthy, sound and unharmed. He heard his father's footsteps and murmured weakly: "I'm fine."
