Another Chance At Being Human

He Chuan transmigrated to an alternate world where everyone could reincarnate.
In this world, all citizens who reached 18 years old could acquire a chance to temporarily reincarnate to another world.
They could reincarnate to various worlds such as an Eastern fantasy world, Xianxia world, Western fantasy world, an urban world with advanced martial arts, or even a sci-fi world of the future.
They would acquire a mission along with the ability required to survive in that particular world.
If they successfully completed the mission, they would become a permanent Reincarnator. They could then embark on the journey of being rich and successful.
If they failed the mission, they would become ordinary commoners. The gates to the new worlds would be forever closed to them.
He Chuan reincarnated to his first world.
[You reincarnated into a world of martial arts. You are an orphan and a loser. You awakened the Deduction System.]
He Chuan devoted himself to deducting various kinds of martial arts. He extracted the essence of each technique and merged them into a unique system.
In the end, he became the greatest legend in Jianghu.
[You acquired S rank evaluation. You may choose to keep the power you gained during this reincarnation and use it again in your future reincarnations.]
He Chuan chose to keep the Deduction System decisively.
He then reincarnated to his second world.
[You reincarnated to a fantasy world. You are talented and are the eldest son in the royal family.]
Sit back and enjoy as He Chuan breaks through the limits of the world and crushes the void.

I Have Awakened The Deduction System

"Where is this broken place? Not only did it not have any true core strength, but it also had such a powerful giant eel." Gu Mingzhou said breathlessly, still in shock.

"Hmph! That's a highly poisonous electric eel, so it's naturally very powerful." Godfather Qin explained.

"Poisonous electric eel? Did you just say that the eel was called a poisonous electric eel?" Gu Mingzhou asked, puzzled.

"It's indeed a giant eel, but who told you that an eel can't be called a poisonous eel? Not only does it have a powerful venom, but it also has electric arcs that can paralyze people!" Master Qin immediately retorted in dissatisfaction.

"That's true," Gu Mingzhou immediately nodded.

The giant black eel was indeed strange. Not only was the venom it spat out extremely powerful, but it also had an electric arc that could confine one's cultivation.

He had been struck by the electric arc and was almost corroded by the venom.
