Coincidence

Why was there a need to come to the Immortal Realm?

This was a question, but could not be considered as one.

Based on Zhou Bao's character, it did not matter to him whether he was at the Immortal Realm or not. Even if he was not there, he had unlimited combat capability, a Supreme Fairy Weapon and his Azure Big World. He could survive well in the Void Universe. Thinking about it, there seemed to be no one there who could do anything to him.

But this was just in a normal situation.

What was considered a normal situation?

A normal situation is one without any tribulation happening. Right now, the Tribulation of Heaven and Earth was taking place. As a Tribulation Taker, even if he had an unlimited fate, what good would run away from the troublesome Tribulation of Heaven and Earth do for him?

When it came to the World-ending Tribulation, he could not run away. He had to face it eventually.
