The Gate of the World is a spiritual treasure of the ninth-order space system. It records the coordinates of the heavens and worlds, not all of them, but there are a lot of them. This is the place that eight generations of powerful people have visited together.

It can be said that the gate of the world was handed down from the ancient times of the world of cultivating immortals, and Zhang Han is its ninth generation master.

When he got it, there were many, many world coordinates in it. Even if he didn't have one, as long as he had been there, he could enter it, and if he wanted to return in the future, he could travel back and forth.
