Binding with Eri Makes Me Supreme Throughout the Ages

After finally beating Re:Zero and getting ready to enjoy a happy life, Luo Lan blinked and found himself transmigrated to the Dragon Raja world. The System he'd thought would never appear finally arrived, late as ever.

The System was called "Myriad Worlds Binding." In each new world, he could choose one character to bind to. Whatever the bound character did, his own attributes would increase accordingly.

[Eri ate omurice in Akihabara and felt great -> Host's mental state recovered to 99%]

[Eri snapped a steel door lock with her bare hands -> Host's strength increased by 1%]

[Eri killed a Deadpool with her "Judgment" -> Host's Word Spirit unlocking progress +0.25%]

[Eri blow-dried her hair completely naked -> Host's willpower recovery rate +10%, and willpower -60%]

[...]

Also, after clearing each world, he could choose any ability from that world to keep permanently.

And once he had cleared twelve worlds, Luo Lan would be able to travel freely between any worlds. Then, never mind immortality: even ruling supreme for all eternity would be within his reach!

Many years later, Ram pushed a strawberry cake toward Eri. Eri dipped her index finger into the cream and poked Rem, who was napping with her head on the table. The little maid gave a couple of sleepy murmurs and buried her face in Feiren's arms as she quietly read. Qian Renxue walked over with tea and casually pointed out an error in the annotations.

Nearby, Su Enxi yawned and looked at the images floating in the air. Exasperated, she said, "So when you invited us out for a team outing, all you wanted was for us to watch you barge into different worlds and torment their villains? You can stop after a couple of hits on Kyubey. Do you really have to torture it for 365 days?"
