"Didn't they have a good saying, be prepared for danger in times of peace?" Xie Yun said with a smile, "Even ordinary, small human beings can go to heaven through their own wisdom, which shows that they are really smart. Maybe one day, They will really blow up our Rubik's Cube world with a cannon, can they not guard against these little clever ghosts?"

System: Are you not a clever ghost?

"By the way, is there really a problem between us?" Zhang Le frowned and stopped shaking his legs.

Tang Guo glanced at a few people lightly, "Now we have four people here, I can be sure, we have no problem."

"How could I have a problem?" Xie Yun said quickly.

Zhang Le also said eagerly, "I'm not a fool. I have harmed the Rubik's Cube world, and it won't do me any good."

"So there are only two people left." Gong Wei said, "but I can't be sure, they have problems, and there may be problems elsewhere."

"You need to see them to know." Xie Yun's gaze fell on the Rubik's Cube in Tang Guo's hand. "You take this thing out, do you want to explain it?"

Tang Guo raised the Rubik's Cube in her hand. At this time, the color order was not disturbed. She pointed to it and said, "This Rubik's Cube has six sides, and each side has a different color. The order is: white on the top, yellow on the bottom, and left. Green, right blue, front red, rear orange. Why in each of our cities, only the city is the safest, other places are full of dangers and various monsters appear?"

Without waiting for a few people to ask questions, Tang Guo continued, "Actually I don't know, but let me make a metaphor. According to our current rotation method, the safe place is the small grid in the middle of each side. This small grid represents To our six cities."

"Then?" Xie Yun was a little confused, "What does this mean?"

"This means that the traitor appeared in one of the six of us."

"What if it's not the small grid in the middle?" Zhang Le continued to ask.

Tang Guo shook his head, "No, according to the law of the Rubik's Cube world, this is only possible."

"why?"

"I think that outsiders have never moved. They are the cities of the Rubik's Cube. Think about it, only the middle place is safe. There are six cities that are constantly moving to the middle position. The Rubik's Cube is still safe. Rubik's cube toys are different."

"Then why can only the small grid in the middle be able to survive? There are ferocious monsters outside the city? Do these monsters have anything to do with the Rubik's Cube world?"

Xie Yun and Zhang Le are a little confused, they have never thought about this problem.

"I once looked through the ancient books of Sin City. There is a record. It says that there is a very powerful person who conquered a powerful monster outside the city, and this person got the key from the trading city and left with this monster. "The palace lieutenant said at this time, the city lord of Rubik's Cube World will retreat after a certain period of time, but some cases will be recorded, for example, whoever goes out will remember clearly.

Tang Guo nodded, "Yes, this is what I was about to say, which proves one thing."

Seeing that the three of them were full of curiosity, she continued, “Those monsters were not conceived from the Rubik’s Cube world. When the Rubik’s Cube world is destroyed, the monsters will be free, just like outsiders, and leave this world happily. Everywhere makes trouble and eats people."

After that, Zhang Le and Xie Yun are both agitated. If so, those who want to destroy the Rubik's Cube world just want to let these monsters out?

"That mysterious soul, we can't detect it, do you think these monsters are where he really hides? After all, we can only control the city where we are."

"What does he want to do?" Zhang Le almost lost his voice. The monster at the gate of the city is not terrible, because it is suppressed by the power of the Rubik's Cube. Without the suppression of the Rubik's Cube world, those monsters could easily swallow a city.
