Kuyech is already the 281st attempt to enter the tunnel, and every time he comes to this location according to Tota's map, but every time he enters the tunnel, it is fine, as long as he goes deeper and reaches darkness, the three of them will inexplicably return to the underground dwelling they built again, back to the state they just set off, and he and Tota have also tried to set off in a different position in the room every time, but each time they will definitely return to the set position.

Tota gave Kuyeqi a nice name for the underground house built by the sea: 'Underground Palace Kang Tsai', which said that the family house in the Frozen City under the sea was called Kang Tsai, which was the name of Du Heng. It has lived there with Du Heng and Ling Wei, and praised the 'dungeon Kangzai' built by Kuyeqi as the most fully functional dungeon he has ever seen.

Kuyech didn't have the heart to joke with Tota, and the only thing he was sad about now was that he had tossed back and forth more than 200 times, but since he first went to the tunnel and came back, he had become a 'fool' as an earthling.

If he hadn't called Du Heng to get up and eat these days, he might have been sleeping in bed, motionless like a zombie. Kuyeqi knew that the energy supply of the earthlings came from meals, so he insisted on cooking for Du Heng every day, but at this time, Du Heng would only smirk at himself when he sat on the chair, and after getting up, his whole person was like losing his soul, except for giggling, he was in a daze. Kuyech, the human's faithful nanny robot, searches his database for all the information related to caring for humans, hoping to find a drug treatment. However, Tota said that this was the result of losing the spirit in his body, and the only way was to go to the place where he had lost it and retrieve his spirit, but the problem was that as long as the two of them reached this position, the two of them would immediately be flashed back to the 'Underground Palace Kangzai', and then still faced the smirking Duheng, Kuyeqi said: "If there is no Du Heng's brain to command, how can the two of us go to find Ling Wei?" ”

Tota was reading again, and he seemed unaffected by the fact that he was always detached, but Kuyech followed him every time he took him to the tunnel.

"Why aren't you worried about our brother becoming like this?"

"Because it was useless to worry, according to the program, we followed the map sent by Lan completely, and did not go anywhere wrong, but the result is always like this, I think he just lost his spirit, and there is no other reason."

"Then you can't let your brother's flesh always be like this, right? What are you going to do with this?"

"Here I protect his safety, you cook for him, and the underground palace you built is also very hidden and strong."

"But you still have a double personality of Ling Wei, and you need to find her body in 3 months, have you forgotten this task?"

"I won't forget my job, but blind and aimless search is not my work habit as an alien companion robot," Tota said seriously. ”

Kuyech laughed and laughed at it: "When is this coming, and talk about work habits." I see that when you come to the earth, you haven't learned other fine traditions of mankind, and it's okay to be official. ”

Today, Kuyech didn't bring Duheng and Tota, it wanted to go to the tunnel again by himself to find directions, this road leading to the tunnel Kuyeqi was already very familiar, good enough for Duheng to eat food for a week, told Tota to take care of Duheng, and then he set off. Kuyech knows that Tota will not drop the chain as long as he is given the task, and will do what a robot can do to complete it, provided that you give him clear tasks and solutions in advance.

Coming to the entrance of the tunnel again, Kuyech did not enter directly this time, as he did last time, but wandered around the mouth to observe, passing by this tunnel mouth hundreds of times, Kuyech never paid attention to what the area around its doorway looked like, because each time he was in a hurry, and hurried to the place where strange things happened in the tunnel.

Kuyech transmitted images of the mouth of the tunnel to his database from all directions, and what was revealed was two words: grave. Grave? Isn't the grave a place where people are buried when they die? Seeing that the mouth was tightly covered with green bricks, each of which was as thick as one foot, Kuyeqi was deeply surprised, and transmitted the picture to the database again, displaying as: 1. Name: Tomb Brick, 2. Generation time: 1700 years ago. 3. Location: Tomb entrance. Kuyech thought that the tunnel that everyone had always thought was a tomb for burying the dead, and Kuyeqi planned to take a good look at the overall shape of this place, so he jumped out of 1 kilometer and looked back at this place, it turned out that this was a huge stone mountain, in the part wrapped in blue bricks, like half a steamed bun, upside down in the ground, and the part close to the ground only had a small hole, that is, the mouth they entered hundreds of times. In addition to the entrance of the cave, the rest of the ground and the four walls, every other section there is a fixed boulder protruding, Kuyeqi found that the role of this stone should be 'falcon', and the gap is also filled with glutinous rice slurry sealed, it can be said that it is impermeable, only the small area of the hole next to the ground is breathable.

Kuyech also found a reminder that the ancient tomb has a mechanism, and you need to be cautious when entering. Will there be a mechanism? Could these mechanisms be able to return Duheng to his body? Kuyech decided to give it a try, he didn't rush into the hole, but found a 'falcons' next to the hole, and pulled out, just when Kuyech pulled out the 'falcon', the blue bricks around the cave mouth moved, like playing cards to fill each other, Kuyech seized the opportunity and jumped into the hole, he hoped that this time the entry would be different.

The 'Hayabusa' was as thick as an adult's thighs, but it wasn't big for a robot. Kuyech did not throw away the 'Hayabusa' in his hand, but carried it into the tunnel, and just as he jumped into the tunnel and walked halfway into the dark area, Kuyech held the 'Hayabusa' in his hand and slowed down, because according to his program records, each time he would return to the same place after a flash of white at a position 2 meters later. Kuyech was very light and light towards the target, 2m, 1.5m, 1m, 0.5m,...... 0 meters. Kuyech stood on the target with both feet, then closed his eyes and prepared to go back, waited for a while, and then opened his eyes to find that the 'Hayabusa' in his hand was actually glowing on the head, saying that there was no light bulb on the lamppost, and that it was a torch, and there was no fire source. This luminous thing also illuminates all the surroundings at once, Kuyech is so strange, every time he comes here, the combined illumination of himself and Tota is much higher than the thing in his hand, none of them can illuminate the surroundings, not only can they not illuminate the surroundings, but the light of the two will be ruthlessly swallowed up by the surrounding darkness, Tota said that this is a black hole, but a black hole with extremely strong gravity can make the escape speed in the event horizon greater than the speed of light, It stands to reason that a black hole is a celestial body with such a curvature of space-time that no light can escape from its event horizon, so how can it appear in a tunnel? By the way, it's not a tunnel yet, it's a tomb, and a black hole appears in a tomb, which is impossible.

With the help of the light, Kuyech looked around, and he found that there was a huge thing like an alien spaceship, like a giant tower, and like a ship, this giant tower could not be seen to be built of any material, but Kuyeqi could see very clearly that each layer was full of all kinds of dry human bones on the earth, men, women and children, and there were secret texts on the huge hundreds of piles, this is a tomb, a huge tomb. Kuyech turned to the side of the tower and suddenly saw a mountain of corpses, as if they were wrapped in white corpse oil, and the translucent state was like jelly of flesh, so these corpses seemed to be made into candles and displayed on the first floor of the turn. Kuyech's program told himself: "643 people"

It turned out that there were 643 corpses here, but how did they die, why did they appear here, at this time, Kuyeqi found that the pillar of light in his hand was dimming a little, a little bit, with its dark point, the scene in front of him was about to disappear, until there was no light, Kuyeqi felt himself 'whoosh', returned to his room 'Underground Palace Kangzai', saw Kuyeqi with a surprised expression, Tota put down the book in his hand, and flew over.

"Friend, are you alright?"

"Tota, I saw 643 human corpses." Kuyech is the most loyal guard of mankind, in his heart, everything is not as important as protecting human life, although it is just a nanny robot with insufficient ability, but seeing so many human corpses today, it does have a big impact on his program system.

"You mean, there's the corpses of earthlings in the tunnels? But I went with you, and I didn't see it. ”

"Yes, because of it" Tona asked Kuyech, who held up the 'Hayabusa' in his hand

"What is this? Matchsticks? ”

Kuyech and Tota looked at the 'Hayabusa' the size of a matchstick at the same time.

"It wasn't meant to be a match"

After listening to Kuyech's description, Tota believes that the 'Hayabusa' may be a key that can pass through darkness, otherwise only spirits can pass through. If Hayabusa is the key, then it doesn't exist, it must be a spirit creature to get through. But what happened to those 643 corpses? Tota said that he could only come back and let him analyze why a tomb with more than 600 corpses could separate his spirit, after all, it was humans who were the most powerful in analyzing human beings.

"If Hayabusa is the key, why are there so many? There are 12 'Hayabusa' at the entrance of the cave, and I've used 1 today," Kuyech told Tota that he had obtained it outside the doorway.

Tota: 'Bro, this kind of reasoning has never been something the two of us are good at, maybe representing 12 nodes? ’

"How about we take Du Heng with us tomorrow and go again?"

Tota looked at Du Heng, who was sitting in the room, flew over, rubbed on him, and flew back, "I still mean that, his spirit is not here, maybe it is locked up in the tunnel, but when we can come back, we should find his spirit first"

"Since you also said that the spirit is in the tunnel, should we go and save his spirit back?"

The two robots without spirits were helpless when discussing spirits, and finally they made a decision to prepare food for Du Heng, and went to the tunnel together to find the answer while he slept.
