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

"I am Zhang Changan from the Zhang family of Great Zhao. May I know how to address this Brother?" Countless thoughts flashed through Zhang Changlong's mind in an instant, but his expression remained unchanged. He cupped his hands at He Chuan with a smile on his face.

"Since you are Master Sheng Kang's friends, you are Great Zhao's friends. There's no need to be reserved." Zhang Changlong immediately turned sideways and made a gesture of invitation.

Zhang Changlong immediately turned around and led them into the Imperial Palace.

"Who are these people? How could he swagger into the palace?"

"Shh! The leader is the Fourth Prince and the old man beside him is the pride of Great Zhao, Master Sheng Kang, one of the Three Great Alchemy Grandmasters of the Eight Treasures Pavilion!"

"Even Master Sheng Kang is here? No wonder the Fourth Prince came out to welcome him personally."
