Xuanhuan: I Am the Forbidden Scion of a True Immortal Clan

[No dumbing down, intelligent villains, decisive and ruthless, no bootlicking heroine, fantastical but not absurd, invincible background, peerless among his generation. Some names are borrowed from Perfect World, but the plot is different.]

The protagonist hails from a True Immortal family, one of the most powerful forces in the Immortal Realm. He battles all manner of powerful ancient beings and constantly hones himself. What secrets lie hidden in the Great Wilderness, the Ruins, and the Eternal Burial Ground?

Note: There is no System. There are absolutely no scenes where an old monster who has lived for a hundred thousand years says or does something incredibly stupid. The villains are intelligent, the heroine does not grovel, and the protagonist is decisive and ruthless. The first twenty chapters are a little dull because they are just setting things up, but it gets better after that.
