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

It turned out that the people here were born at dawn and gone at sunrise.

Young in the morning, strong in the afternoon, old in the afternoon, dead at sunset.

Just now, she asked him how minutes old he was, which meant how old was he.

An hour was equivalent to ten years for an ordinary person, and a lifetime was equivalent to one day for an ordinary person.

"Little girl, can you take me to the place where you were born?" He Chuan smiled kindly.

"What are 30,000 days old people doing? I'm sure it'll be boring." The little girl asked non-stop. When she learned someone could live for more than 30,000 days, she covered her mouth in surprise.

Cultivators thought that a few thousand years of lifespan was not enough. Ordinary people in the mortal world thought the same. Living for a few thousand years or even eternal life was boring. It was simply a form of torture.
