The heavens have no boundaries, and all realms have no rules.
A simple history book and a ray of extraterrestrial light accidentally touched allow mortals to break free from the shackles of the mortal world and step into the endless ups and downs of another world. .
With a mortal body of flesh and blood, carrying an ancient book, he traveled through thousands of foreign worlds with different laws.
The wild ancient plains where thorn-walking beasts are rampant, the floating islands in the sea of clouds where spiritual trees live in the sky, the deep-sea royal city where the eternal sleep is explored, the wasteland of silence where the machines are rusting, and the clouds and the sky where the giants are looking down...
See the various states of living beings, watch the decay and prosperity of all realms, expand the unseen scenery in the world, and record the history of heaven and earth that has never been passed down.
Don't ask about the way back, don't chase fame.
Traveling through all the heavens and all realms, using human steps, I can measure the vastness of all realms.
