After Ten Thousand Years in Seclusion, I Became the Sect’s Founder

[Invincible + immortality + sect + System + decisive and ruthless + no hiding his power]

During a seclusion session, an accident causes a transmigrator to transmigrate into Qin Wujiu. Qin Wujiu slaps the transmigrator to death and immediately obtains the Immortal Sign-In System that came along with him.

The Immortal Sign-In System imposes a mandatory beginner mission: stay in seclusion for ten thousand years. Qin Wujiu has no choice but to retreat into seclusion.

Ten thousand years later, the world has changed dramatically. The once-powerful Lingxiao Sword Sect has declined because of a series of upheavals.

…

“Heh heh heh! Is this the Lingxiao Sword Sect that was so powerful ten thousand years ago? How did it become so utterly helpless?” the people of the Demon Domain jeer.

Just as everyone prepares to fight to the death, a detached voice rings out: “Oh? It’s only been ten thousand years, and you people from the Demon Domain have gotten this bold?” (This book doesn’t follow the traditional immortal-cultivation model. You can think of the cultivators as martial artists who can cultivate immortality.)
