I Tossed a Demonic Contract into the Buddha's Merit Box

Although the power systems differ, the vastness of the world and the variety of power systems provide ample writing material. You can complete one world's questline before moving on to the next, and add a main storyline interwoven across different worlds. The protagonist can be invincible, but pay attention to how he handles various situations. Good luck!

What's going on? That's it? I just took my pants off and you were already done? That's too short...

It's alright, personally, I think it's pretty good.

Well written, keep it up!
