MTL - Space Speed Xing Hen - ~ Grand recommendation "Jian Xia World" grand version

Liola—the best assassin in his world—has vowed to kill no more. He was being chased by an assassination organization when he accidentally dropped into a parallel universe: through a dimensional gate and into poor teenager Kaiser’s apartment. Instead of going to the government shelter for lost dimensional travelers, Liola and Kaiser wind up going to school together.

Liola has been trying his best to live the life of an ordinary person, but after certain things happen one after the other, he begins to realize that being an ordinary person could be harder than being an assassin.

“Don’t touch there, it’s dirty…” Su Yanyun flushes. The man smiles slightly and wipes the mud stains on her feet.

“My baby, it’s not dirty.”

Overnight, Young Master Yi changes from being a clean freak who is unable to even get close to his relatives to being desensitized and doting on this little woman of unknown origins.

“Hubby, the baby in my belly is calling you!”

Even if he has to cross half of Earth, Young Master Yi would still fly back overnight.

“Boohoo, Hubby, they called the baby a bastard!”

Capture all the scums who spread this rumor!

“Hubby, I want to bring our baby on a trip!”

Young Master Yi: “Don’t forget to bring your luggage.”

“Which one?”

“Me.”

In this life, I will live for you.

Have you ever thought that the state of the world as it presently is, could revert to the laws of the ancients? When a series of strange incidents beginning with the disappearance of his friend led Luo Yuan to question the possibility of an apocalypse, he becomes embroiled in the midst of a global-scale chaos.

Evolution has turned the flora and fauna of the vast and bountiful Earth into something that had never been seen before. Coincidentally, the all-dominating Homo sapiens have ended up at the bottom of the food chain. From mystery to crisis, will Luo Yuan discover a means of saving humanity by racing to the top of the food chain? Or will he strive in accordance with the law of the jungle? It is the dawn of an age of the survival of the fittest.
