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

Dark clouds rolled and lightning surged.

The green-eyed black dragon flew out from the void, letting out a deafening roar.

Guanhai County collapsed on the spot, and thousands of living beings died under this attack.

In the distant void, two figures observed He Chuan through special means.

"The Eunuch King should be able to force the Ghost King to reveal his trump card." The Celestial Cultivator smiled. Beside him stood Emperor Tianfang.

"What if the Ghost King dies without a trump card?" Emperor Tianfang suspected the Ghost King was He Chuan, but he wasn't so sure.

"It means that he hid it well." The Celestial Venerable continued,

Heavenly Emperor Tianfang thought to himself, "What a good fellow." So he was certain the Ghost King was a traitor.

The Black Emperor's Dragon Fist descended with the power to destroy the world.
