My One-Sword Strike That Felled an Emperor Is Out, and the Empress Is Searching the Whole Empire for Me!

[Transmigration + System + Invincible Protagonist + Empress + Villain + No Goody-Two-Shoes]

After transmigrating to a fantasy world, he awakens a sign-in System and becomes the sword heir of a supreme sect.

From the start, he kills a young Great Emperor, drawing the Empress’s attention. She mobilizes the entire nation to hunt him down.

“Ding! Sign-in successful. You’ve received an SP reward: the Chaos Sword Body!”

“Ding! Sign-in successful. You’ve received the Three Swords of the Dao!”

“Ding! Sign-in successful. You’ve received the Demonic Eyes of Destruction!”

But he never expected the System to do more than just sign-ins. It could issue missions, too.

“Kill the rabbit demon in the Tiandou Great Forest and receive one supreme-grade elixir!”

“Steal Lin Qiye’s sheep and receive a massive cultivation boost!”

“...”

Years later, a young man emerges from the Sword-Imperial Immortal Sect. One sword splits the heavens; another divides the earth. The world trembles!
