My Arch-Enemy Is Reborn Again

Continuing the story and filling in the gaps (the writing style may be inconsistent in places).

An atypical rebirth story.

Original title: "Reborn Again and Again"

A silly blurb:

First life:

Ning Muhuan follows the script and vividly demonstrates all the essential qualities of a scumbag top, giving someone a thorough runaround.

Fang Susheng: Heh.

Second life:

Ning Muhuan, holding the script: Wait, weren't we supposed to have a tragic romance between a scumbag top and a pathetic bottom? Why is this guy rebelling?!

Fang Susheng holds a sword to the emperor's throat and proceeds to beat him up.

Director: Stop hitting him! Someone's going to die!

Third life:

The script is useless now.

Fang Susheng builds a force nearly as powerful as the imperial court.

Ning Muhuan makes sure he has no chance to rebel.

Except...

Fang Susheng: I'm getting revenge! I'll kill that dog emperor!

Ning Muhuan: Revenge? Not in this lifetime!

Then comes a clash of blades, a world-shaking commotion, utter chaos, and finally... they die together.

Fourth life:

Great. Not only is the script gone, but so are their memories.

They meet without recognizing each other.

Fang Susheng: Who are you? Wait, why does this person look like the one who keeps appearing in my dreams?

Ning Muhuan: Where is he? Wait, who was I supposed to torment?

Their story is only just beginning in this life.

Ruling over tens of thousands of miles of rivers and mountains,

Snow and wind on the frontier soak through my robes.

No one speaks of all the things that came before.

Looking back, old friends have gone their separate ways.

Better to ride home to the old country,

And tread the familiar ripples on a rainy night.

An old friend raises a lamp, but says nothing to the guest.

It turns out you were my destined nemesis all along.

Also known as "Two People Reborn Again and Again, Testing Each Other"

They switch roles, they switch roles, they switch roles.

Theme: Every rebirth repeats the past, but perhaps this life will be different.
