On the vast continent called the "Three Source World", humans, monsters, and demons have coexisted for tens of thousands of years. Each has developed a completely different cultivation system, but they are bound by the same ancient prophecy: "When the three sources merge into one, the way of heaven will begin to be complete."
The protagonist Lin Yuan went from being an orphan struggling to survive to discovering his special physique and being forced to get involved in the disputes between the three clans, gradually approaching the truth of "three sources in one". He must find a way to integrate among the pursuit, wooing and conspiracy of all forces, and at the same time face the ultimate choice:
Is the unity of three sources the only way to save the world, or the key to unlocking the final seal?
