(No System, no invincibility, no brainless decisions, no harem, ensemble cast, highly intelligent villains, turning the tables in desperate situations, fictionalized global setting. Read with caution if any of this bothers you.)
After the college entrance exam, Yang Jie returned home and witnessed the massacre of his entire family. Overwhelmed with grief, he collapsed on the spot. When he woke up, he discovered that the world was now overrun by ghosts and monsters, and that he had become a beautiful woman's slave.
By chance, Yang Jie unexpectedly awakened the superpower [Infinite Adaptation]. After surviving one deadly incident after another, he drew ever closer to the truth behind his family's slaughter...
“Now that I'm invincible in the world, why can't I put an end to the endless turmoil of this mortal realm?”
“So what if you're invincible? Yang Jie, do you truly believe that you alone can change the countless evils humanity has committed over thousands of years?”
The protagonist is too weak; everyone wants to get rid of him, and he can't even kill anyone.
Not brainless, not bad.
It's so good!!!
Good! Good! Good!
