Cao Yu was an ordinary university student until he accidentally activated the System and began traveling through the myriad realms.
He arrived in the world of Dragon Raja, saved Uesugi Erii, and stole the Seven Sins.
He spent three years in the world of One-Punch Man, discussing the secrets of strength with Saitama. Shamelessly, he asked Bang and Bomb to take him on as a student and learned Flowing Water Rock Smashing Fist and Whirlwind Iron Cutting Fist.
In the end, he beat up Monster Garou and learned Monster Calamity God Slayer Fist.
Then he arrived in Star Voyager, gave Clay two hard slaps, and stole his Rainbow Stone and Gunpowder Crow...
Cao Yu was having the time of his life, but one day he arrived in a strange world that had lost all order and knew only bloodshed.
In this world, only the strong survive, and darkness destroys the kindest part of people's hearts.
I usually like to watch anime about different worlds. This is the first time I read a novel with this theme. The unique style and the easily imaginable image of the male protagonist can relieve my boredom when I am bored. There are too many things that go wrong in life. Watching the male protagonist fight monsters and progressing all the way, watching other people's lives that are magnificent, full of passion, youth, and love, satisfy your own imagination.
