Where did humanity's ancestors come from?
How did cells come into being?
This question had troubled humans in two different worlds for a long time, and it had also been tormenting Liang Zhi.
Especially after he realized that he might be the only person who knew two kinds of cells existed.
A sense of mission arose within him.
Or perhaps it was merely curiosity born from the depths of life itself.

So he began constantly exploring the Great Tree Cave, gradually establishing himself and making a life in this world.
He also came to know a group of companions from this world.
During his interactions with the humans of this world, Liang Zhi increasingly felt that there was no real difference between the two forms of life.
Finally, after one routine exploration, he discovered Strange Eggs filled with Transparent Liquid underground near the Great Tree Cave.

But Liang Zhi did not choose to do that. Having spent so long in
