After Rewinding My Death, My Archenemy Got a Happy Ending

I was reborn, back at the beginner level.

Outside the glass elevator, the rookie I'd once killed was staring coldly at me.

"Are you going to stab me in the back again this time, Jiang Yan?"

Unfortunately, neither of us knew that the main System had just issued a new notification:

[High-dimensional soul resonance detected. Lifetime Partner System bound to you.]

I stared at our shared life force, split evenly between us, lost in thought.

Later, in a haunted funeral hall at midnight, when a vengeful spirit gripped his throat, matching bruises appeared on my fingertips.

Once our two-person ranked matches began, every dungeon boss went berserk:

"How can two paradoxes possibly coexist?!"

At last, amid countless shattered mirrors during the final battle, he smiled at me:

"Can you guess who made our souls resonate?"
