Within the Chaos world, Ye Fan was mulling over what resources to upgrade his Five-Six Profound Body, while continuing to use resources to enhance the Chaos world.
Then, all of a sudden, the previously tranquil Chaos world started to tremble.
Far from panicking, Ye Fan was thrilled.
This indicated that the Chaos world was about to upgrade from the Little Thousand World to the Great Thousand World.
The next moment, the area of the Chaos world began to rapidly expand.
In a short time, it had expanded tenfold.
The area is an important factor in determining the rank of a Chaos world.
After the Chaos world was upgraded from the Little Thousand World to the Middle Thousand Worlds, the Great Tao that maintains the operation of the world became richer and more potent.
The originally thin spiritual power also began to grow denser.
Although there were creatures within Ye Fan's world, their cultivation levels were not high and incomparable to other Middle Thousand Worlds.
