Yin Zhong!
He was the major villain of this world and also the most powerful entity in existence.
He was an immortal who had lived for five hundred years.
Ordinary weapons harmed him at a speed far slower than the rate at which he healed, and he also knew sorcery, able to freely summon wind, rain, thunder, and lightning for his own use.
If not for the curse-level injury on his chest that continuously drained his blood, he could be called a god among men.
In terms of mastery of sorcery, not a single person in the entire world could match him, yet someone as strong as Yin Zhong had no thoughts of ruling the world, choosing instead to hide covertly among mortals.
Imperial Sword Manor!
This was established by Yin Zhong's eldest son, Yin She, born when Yin Zhong was thirty years old. Through five hundred years of shifting vicissitudes, with dynasties changing several times, Imperial Sword Manor still stood tall and unfallen.
Because...
They had a living ancestor—Yin Zhong.
The protagonist group called him a great demon king and a heinous villain, but in truth, Yin Zhong's level of danger was not all that high.
Yin Zhong was not the kind of villain who killed people on a whim just to liven things up; in the absence of a conflict of interest, he would not attack people casually, and he was even more polite than righteous people.
However...
The reason he was a villain was precisely because, although he possessed genuine affection and understood politeness, when necessary, whether it was his descendants or his benefactors, he would harden his heart and kill them.
Yin Zhong had been furious lately.
Members of the Tong Clan, who had not appeared for five hundred years, had reappeared in the mortal world.
