Most legends of Immortal Gods were also deeply connected to these rare, ancient books.
Chu Mu didn't know whether the legends were true or not.
But at the very least, judging from these ancient texts, the wise minds of this world had indeed embarked on all sorts of explorations into the mysteries of the human body back in ancient times.
The most profound among these rare, ancient books even touched upon the existence of God.
But this exploration clearly had a tragic quality to it.
After all, Essence, Qi, and Spirit are fundamentally interdependent. In this Spiritless World, the human body alone simply cannot support the growth, let alone the transformation, of Essence, Qi, and Spirit.
Even if a peerless genius managed to touch upon the existence of God for some reason, that contact would be nothing but a fatal poison.
