Chapter 209: The Tip of God's Iceberg_1

"So, once you have a stable entry point, it's best not to change it lightly. If you have to change it, it's almost equivalent to giving up your current door. Having a door is a good thing, but it's a taboo to keep switching back and forth between different doors,"

"I see..."

Mu You nodded.

Even Vivian and Grandma Lin Xue did not know about this rule. They had been living in the Star Spirit World, where doors were immobile and could not be opened. The door in the tundra was only controlled by Vivian through inter-world manipulation, which affected the world on the other side.

Thus, it was the only door they had access to. There was no opportunity at all to jump back and forth between different doors.

"Thank you."

Mu You sincerely thanked the Blood Emperor. It was fortunate that someone would tell him about this. Otherwise, he could easily fall into the trap without knowing it.
