Entering the cave, a huge and opaque plastic bag wrapped in a giant cylindrical object, surrounded by stairs, under the huge cylinder there are several computer equipment, some computer screens appear and disappear line by line code, some computer screens rotate a 3D simulation of a cylinder, and some are showing something incomprehensible.

Several staff members were watching the computer, and some were wearing anti-shot suits on top of the cylinder and holding some small instruments to survey something.

"What is this?" Xiao Shi said in surprise and stepped forward again to see what was inside the plastic bag.

When Xiao Shi opened the plastic bag, he saw a translucent smooth purple crystal, which was so purple that it was naturally black, making people's vision infinitely elongated and their eyes infinitely focused inward. Xiao Shi stood motionless in shock, the pupils of her big eyes began to dilate, reflecting the infinite blackness, her whole body was as stiff as wood, and she looked at it blankly, which was clearer and cleaner than when she found it before.

Recording it and pulling the plastic bag back, Xiao Shi's vision was suddenly cut off from the depths of the purple crystal, and he came back to his senses and immediately collapsed to the ground.

"You're still a weak woman at heart, and you're usually so domineering, haha." Record teased.

Xiao Shi narrowed her eyes and rubbed her eyes again. Hearing Lu say this, he pouted again and rolled his eyes.

Tianyun looked at the top of the cylinder and scanned it directly to the bottom and kept looking, as if this thing was extending infinitely downward, and suddenly felt that there were black ripples rippling in the center of this crystal, and the ripples passed through everyone present, as well as any obstacles.

"It's still very deep in the ground, and I can't dig it any further, otherwise it will be difficult to work." Recorded as if he had seen through Tianyun or something

"What is this?" Tianyun held back a sentence for a long time

"I don't know, I've never seen it, and there is no record of anything like that in any book, it is electrically conductive, magnetic, and harder than diamonds, according to the data analysis obtained by the computer, its mass is unusually large, as long as a small cubic centimeter, about 1 ton in weight, and the distribution is also very uniform." Lu smiled as he spoke, and picked up a pebble from the edge of the crystal.

"I'll do a magic trick on you." As soon as the stone in his hand was released, the stone made an astonishing parabolic motion and fell in the direction of the crystal.

Tianyun and Xiaoshi were both surprised.

"You can try by shaking your hands, and you'll know why the stone is parabolic." As he spoke, he waved his right hand.

Tianyun also waved his right hand, waved it in the direction of the crystal, and waved it away, and suddenly there was a force to pull Tianyun's hand back in the direction of the crystal, although the force was small, but it could indeed be felt.

From the beginning of the entrance, I found that the floor was unexpectedly clean, and there was always a gust of wind blowing in from outside the cave, blowing Xiao Shi's long hair fluttering, and this gust of wind never stopped.

"This crystal came out?" Tianyun felt that it was the gravitational pull emanating from this crystal that attracted it.

"Yes, it is this thing that emanates from it, and for the first time, human beings feel gravity in addition to gravity, there is another real gravitational pull. This thing is by no means something on Earth, it may be a meteorite that fell before. However, this meteorite is not found in any literature. What an amazing existence it is," said Lu Meizizi.

"Okay, I can go back to you." Recorded clapped his hands and said to Tianyun and Xiaoshi.

Tianyun still stared blankly at the depths underneath, and a sense of familiarity became stronger and stronger.

Lu patted Tianyun on the shoulder, "This is not the place for you to come, I will take care of these things." ”

The black ripples in the depths of the crystal gradually rippled, and when the ripples swept through Tianyun's brain, the picture in Tianyun's mind flashed, and when another ripple swept by, the picture was clearer, when he was five years old, Tianyun and a few friends were playing hide and seek in this ancestral hall, at that time, Tianyun hid behind a big tree behind the ancestral hall, peeking to see if the friends in the ancestral hall had found themselves.

At this time, black ripples came from the mountain and hit Tianyun, and then Tianyun saw the back of his head, and then slowly approached, getting closer and closer.

"Tianyun! Sky Cloud! Lu pressed his hands on Tianyun's shoulders and shouted Tianyun's name while shaking Tianyun.

The picture in front of Tianyun's eyes changed to Uncle Lu's face, and then he came to his senses, and the ripples disappeared.

After that, Xiaoshi took Tianyun out of the bombing hole, and Tianyun lowered his head all the way and thought, what was the picture?

"Do you want to see the village doctor, you don't seem to be in a very good state." Xiao Shi said as she walked while looking at Tianyun.

"No, by the way, do you remember the scene when we used to play hide and seek in the ancestral hall?" Tianyun asked

"Which time? We've played it so many times."

"Just, I'm hiding behind a big tree outside the ancestral hall."

"Huh? Hiding outside the ancestral hall is a foul act, okay! Isn't the place of hide and seek in the ancestral hall? We do it every time. Except for the one you found behind the stone behind the ancestral hall when you played missing, didn't I tell you before? So forgetful? ”

"What do you say about me after that?"

"I fell asleep right behind the rock, and I vomited blood from my mouth, but nothing happened after the examination. At that time, many adults were very nervous. ”

Tianyun wondered why he didn't have any impression at all. Remember that time hiding behind a rock, and then what happened? Why can I see the back of my head? Tianyun touched his forehead and felt that his forehead was starting to get hot.

Suddenly, a shout in the distance broke Tianyun's thoughts, and he saw many people coming out of the house and running in a certain direction, everyone in a hurry.

"What are they doing here?" Xiao Shi questioned.

"The direction they went seemed to be the hospital, it seemed that something had happened in the hospital, what happened to the unconscious people? Or is there something significant about it? Tianyun looked in the direction where the crowd had gathered.

"Uncle Deng, Uncle Deng also fainted in the rain three months ago, and he is also in the hospital now" Xiao Shi pulled Tianyun to the hospital to have a look.

The hall of the hospital was crowded with people, everyone was discussing, saying that Sha Yin, who had been in a coma for three months, woke up, and when Sha Yin's relatives went to visit Sha Yin tonight, Sha Yin was lying on the hospital bed with his eyes open and blood flowing from the corners of his mouth, and when he woke up, he was in a daze and spat blood in his mouth. Doctors are also doing a test for this.

As soon as the news spread, those in the village who had fainted at home, or relatives who had fainted in the hospital, rushed to the hospital to see what was going on. What the hell is going on?
