The following three realms are Gray Body, Black Body, Cyan Body.
Li Yuan speculated that in these three realms, the Earth Soul could have a terrifying breakthrough, possibly marking the "Late Stage" in the three cultivation systems.
And...
To break through the first minor realm, one must first have a body with "extremely dense Yang Qi."
For ordinary people, trying to make themselves full of Yang Qi is actually very troublesome.
But for the Ice Barbarians, who can "accumulate" Yang Qi from birth, they are naturally suited for cultivating the Earth Soul.
And the Barbarian King—Zhenyan Huang, could indeed be called a genius among them.
As for Li Yuan...
Li Yuan thought he might surpass a genius by just a little bit.
Just a little bit.
After all, Zhenyan Huang is his son, yet when he had Zhenyan Huang, his body wasn't a Withered Fire.
Upon realizing this, Li Yuan was quite invigorated.
As for the cultivation method, it's knowing what's easy but doing is difficult.
