The next few days of fighting were spent without danger, and with the help of Ah Chu, a powerful thug, everyone didn't feel much hardship. Along the way, following Ah Chu's footsteps, he easily walked through a room with one. At present, the enemies they are facing are still mainly sentinels, but some of the defensive machines that can still operate autonomously have added a little difficulty to Yuan Dou and his party. But after all, there is a super powerful robot walking in front, any trapping is useless, after Ah Chu has passed, Yuan Dou and his party who followed have already been prepared, because of the lack of suddenness, the trap does not constitute a threat.

However, after a few days of exploration, Ah Chu gave everyone bad news, it found that the internal space of the spacecraft did not match the size of the space calculated by the external scanning, in short, the internal space was larger than what was seen now. At this time, the room that the group walked through was just walking in the surface space of the spaceship, and the spaceship used advanced space folding technology, in fact, the spaceship was not connected one by one, but many spaces were connected, and each time they passed through a room, it was like passing through a space.

Yuan Dou and the others didn't know the characteristics of the space, and it was only when the group walked through a room and suddenly saw the scene outside the spaceship that they realized the mystery. The crowd had already walked around the ship, and they could already see the room they had taken when they entered the spaceship on the other side.

"Ah Chu, what's going on."

"According to calculations, the total number of rooms we walked through was far smaller than the actual space of the spaceship."

"What's going on here?"

"At the moment we have walked through thirty rooms, and according to the actual size of the ship, we have walked through about half of the spaceship, so we calculate that there is an 80 percent probability that we are jumping from one room to another, and a 20 percent probability that there is another room hidden in each room. Overall, the interior of the ship is folded so that the other rooms disappear. ”

"So what are we going to do?" Yuan Dou asked.

"Among the thirty rooms we have experienced, there must be a key to the inner level, as long as we look for it, then theoretically we can also reach the inner level."

What Ah Chu said Yuan Dou didn't fully understand, but the next task was to know, as long as he found a special room, then he could enter the interior of the spaceship. Since the surface rooms had been completely cleared and there were no enemies, the group decided to separate and explore, carefully examining the rooms they had walked through. Then everyone divided into two teams, one team walked along, one team walked backwards, and finally met in the middle room.

For the sake of safety, Yuan Dou, Lian Yan, Ye Xi together, Ye Yang and Ah Chu together. In Ye Yang's weak speech shouting about substitution, everyone began to explore again. Although Yuan Dou knew why Ye Yang wanted to change people, because Ah Chu was not a bosom friend who could talk happily, and most of the time Ah Chu was just a silent listener, but Yuan Dou didn't pay attention to it, shrugged his shoulders, and as the saying goes, a friend of the dead Dao is not a dead poor man, so he can only wish him good luck.

The three of them walked back backwards, not letting go of every room, every piece of equipment, every thing, every wall, and the metal pattern on the wall. Time passed in this search, and when Yuan Dou and the three of them came to the agreed room, more than ten hours had passed. When the two teams met, they shook their heads at each other, but nothing was gained.

There was no way, everyone sat together again and discussed, but the discussion came and went, and there was no clear goal.

"Why don't we think about it from a different perspective?" Lian Yan said.

"From what angle?" Yuan Dou asked.

"Think about it, what is this interior space for?"

"I think it's definitely an important part of the ship, and the bridge must be in it."

"So what needs to be done with something important?"

"Hide?" Ye Yang said.

"No, no, think again."

Everyone pondered and pondered, their thoughts flew wildly, and the donkey's lips did not match the horse's mouth.

"Well, protected?" Ye Xi said uncertainly.

"Yes, that's it, good things have to be protected." Lian Yan said happily, and then hugged Ye Xi.

"And then." Ye Yang asked.

"You're so stupid, of course you're the one with the most enemies, that's it." After Yuan Dou reacted, he despised Ye Yang, but in fact, he finally found someone stupider than himself in his heart, and he was very happy.

"Now that you have the clues, let's go now."

This time, everyone was very fast, and after a while, they came to the room where Ah Chu had faced more than two hundred sentinels, and there was a fire in the corner of the wall that had been used at that time. After arriving in the room, everyone separated from various places in the room, eager to find the key. Yuan Dou glanced back and forth on the door, and had to knock on the wall from time to time, Lian Yan paid attention to the east wall, checking little by little, Ye Xi and Lian Yan checked the wall behind her, Ye Yang lay on the ground, checking step by step, but Ah Chu was different, I saw it standing in the middle of the room, its body did not move, and its head was scanning the room in a circle.

As time passed, everyone's enthusiasm slowly extinguished, and after inspecting the east wall, Lian Yan stopped moving, holding her chin with her right hand, and was trying to think. At this time, Yuan Dou had already finished checking the door when he came over, as well as the wall where the door was located, looked at Lian Yan, who was thinking, and walked over.

"Lian Yan, don't try too hard, think too much, you'll lose your hair." Yuan Dou just saw Lian Yan's sad face and wanted to use a joke to cheer her up, but Lian Yan didn't seem to need it.

"Bastard, don't disturb my thoughts, you man who never uses a head." Lian Yan rethought after driving Yuan Dou away.

The room was empty, there was no special equipment, only a huge number of sentinels, now that the sentinels had been resolved, all that was left was the four walls, the ceiling, and the floor. The room is definitely used a lot, and generally does not put it in the ceiling, the ceiling excludes. The all-metal walls are smooth, and there is not even a pattern, as if it is a whole, and I don't want to look like a mechanism. So is it only on the ground?

Looking at Ye Yang, who was lying on the ground and kept looking, Lian Yan didn't feel like she was on the ground, so where would it be? Lian Yan looked around, the closed room didn't even have a window. Window? Oh, it's definitely on the door!

How were the sentinels lined up when we first came in? As if facing this side, Lian Yan pointed to the left-hand side, which was where Yuan Dou had already finished checking. Then keep what you want to protect behind you, this is it, yes, it must be like this.
