I Ended Up with My Nemesis

Yan Jing, the junior grandmaster of the foremost immortal sect, was enlightened by the Heavenly Dao. He commands the Law of Good and Evil and was appointed the Punisher of Evil, dispensing rewards and punishments on Heaven's behalf. He slew countless villains, becoming a cold-faced judge who once struck fear into every criminal in the cultivation world.

In the end, he fulfilled his duty to the letter, perishing together with the evil spirits in a great battle...

Wait, it seems he might still be alive.

One hundred and thirty years after his death, Yan Jing came back to life.

Returning to the mortal world, he found that his godlike master, the revered leader of the Big Dipper, was gone, leaving behind a handsome and exceptional junior apprentice brother.

But no matter how Yan Jing looked at him, this junior brother didn't seem like a junior brother at all.

On the surface, he was refined and upright, the very model of a righteous cultivator. In truth, his origins were unknown and he was riddled with suspicious details. The first time they met, the Law of Good and Evil judged him to be "utterly evil."

The only thing Yan Jing was sure of was that this man had a great deal of interest in the Law of Good and Evil... on the body of the Punisher of Evil himself.

As it happens, Xi Qitu wants his Law of Good and Evil, while Yan Jing wants Xi Qitu's life.

From then on, they put on a show of civility in public and enthusiastically fought behind closed doors. One would talk, the other would cut in. One would kill, the other would steal the kill. They clashed openly and covertly, again and again, until finally...

They kissed?!

The cultivation world's onlookers, who thought the two were completely incompatible, stared in shock.

Yan Jing hurriedly shoved the man in front of him away. "That was a mistake!"

Xi Qitu: "Mm. Mine."

A scheming, tsundere top who "didn't mean well, but ended up giving his heart" x a stubborn, sharp-tongued bottom who "still talks tough even after being thoroughly ravished"

Before you read:

1. A green-tea celebrity top x an arrogant, unruly bottom.

2. They aren't destined enemies. Their relationship develops gradually.

3. This is my take on the setting, with lots of original worldbuilding. Please don't tell me how to write it.

Theme: Hearts are complicated, but affection is precious.
