Chaos Warlord: Reincarnated in Eldrich with the Devil System! - Chapter 263 260: The Lesser Dimension

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.

Crossing over to an independent urban world where martial arts and immortal law coexisted, the only thing Lin Shen could rely on was his clone’s golden finger.

“Clone cultivation, the host becomes stronger.”

“Clone [Pure Flame Body]: Flame attribute techniques cultivation speed +300%, Blazing Flame Palm, Melting Hand, Pure Flame Sword Skill… Any flame attribute techniques at your service. You can become a master in a day!”

“Clone [Natural Daoist Body]: cultivation speed +500%. All martial arts techniques can be understood at first glance, and will be integrated, crushing all geniuses!”

“Clone [Non-self Sword God]: Sword art technique power +200%, sword art technique cultivation speed +200%. No matter how strong you are, I will cut you down with one strike!”

…

“You never know how many clones are trying to cultivate behind the person you are talking to in front of you!”

“What does it have to do with me if my clone did it?”

“Don’t try to outnumber me cuz you can’t!”

Transmigrating to the disciples of the Demon Sect, and relying on the skill modifier to become a giant of the Demon Dao.

[Detected the technique “Blood Nerve”, relying on devouring blood to practice]

[Side effects: easily affected by the spirit contained in the blood, becoming bloodthirsty, bloodthirsty, mad, and even brain dead]

[Ding! The modification is complete, and the side effects are cancelled]
