Villain: This Cautious Demon Sect Saint Is Truly Impressive

[Villain, ruthless warlord, super sweet, arrogant protagonist.] Qin Shao transmigrated to a fantasy world. His master was the sect leader of a major immortal lineage in the Sacred Realm, the foremost of the Supremes, an invincible being whom even immortals could not surpass while in the mortal realm. His father's clan was the leading immortal clan in the Sacred Realm, and an ancestor from ancient times had even ascended to the Immortal Realm. His mother's clan also belonged to an immortal lineage, the Pill-Origin Sacred Ground, so he'd grown up eating precious pills and elixirs like candy. He was also the Sacred Realm's number-one prodigy. Yet with such a perfect setup, he was still a villain destined to be face-slapped by the protagonist, a textbook stepping stone. No! He wouldn't accept this. He would fight back! Ding! The Ultimate Villain System has successfully bonded. Plunder the protagonist's fortune, become the ultimate villain, and make sure the protagonist's whole family ends up together in the afterlife.
