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

"White Tiger God, please bless us!" the eighteen saint cultivations of The White Tiger Palace chanted the name of Buddha. They immediately felt that something was wrong and stepped forward. "Sect Master!" The eighteen saint cultivators of The White Tiger Palace shouted at the same time.

"White Tiger God, please bless us!" The eighteen saint cultivators of The White Tiger Palace lowered their heads and put their palms together. Their faces were solemn. The headmaster had ascended to Nirvana. It was sad and joyful. They turned their heads, but they could not see He Chuan in the attic!

"He Chuan, that dog thief, is really powerful!" A middle-aged monk said slowly.

"I'm afraid he's already out of the capital!"

"This dog is really bold. He actually..."

"Let us split up and search for this devil!"

This Dog Thief is So Bold, He Actually...
