Before the Migration

This is the first time I'm reviving low-dimensional lifeforms, Xu Jingming thought. As a high-dimensional lifeform, he had observed the River of Spacetime countless times and had a deep understanding of it. In fact, he needed to possess a profound comprehension of the river's intricacies to create an inner universe.

Buzz!

With a single thought, Xu Jingming's inner universe spread out, forcing the River of Spacetime to appear.

This is just this universe's River of Spacetime. He peered at the countless amber-like figures floating in the river and noted, It holds low-dimensional lifeforms, so this River of Spacetime is naturally very weak.

The River of Spacetime was divided into levels.

In a universe, it contained all the low-dimensional life imprints that had died in that universe.
