There are countless worlds in the entire chaos, but there are always only nine top-level Great Thousand Worlds, also known as half-step true worlds. When the tenth top-level Great Thousand World appears, the Great Dao will lower the Eternal Machine. The world that obtains the Eternal Machine will annex the other nine worlds and advance to the Eternal True World.

In the end, the prehistoric world and the nine worlds and the worlds they led were all destroyed. After the final destruction, they were reborn into the boundless universe. After a long time, some new balls in the universe began to give birth to life and develop civilization, and the story begins here. From then on, war broke out among thousands of races to compete for the leading role in the eternal true world. The prelude to this war began.
