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

"Father, this is what happened." Yao Jiaquan, who was standing in the middle, was furious.

He didn't know where did his fifth brother made such an arrogant friend.

"Not only did he let Lin Ruo'er kill Xu Hai, but he also broke Fourth Prince Chu Yuan's right arm in front of everyone. This was absolutely despicable!"

"Second Brother, what you said is wrong, right? Chu Yuan is clearly the one who is meddling in other people's business!" Yao Qiankun, who had just returned, immediately retorted.

"Shut up!" Yao Jiaquan interrupted Yao Qiankun.

"Although the Fourth Prince had long lost his power in the Imperial Court, he had only lost the right to compete for the throne. His status as a prince was still there."

"The Chu Emperor had even handed over the heavy responsibility of military supplies to the Fourth Prince."
