I don’t know how to write an introduction. The few times I wrote it before, the more I wrote it, the more ugly it became. Let’s keep it simple:

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.

Transmigrating from the Apocalypse to a technologically developed, peaceful world, Qiu Yu’s killing skills cultivated through hundreds of life-and-death situations suddenly lost their use, and even his body turned into a weak, squeamish…

Qiu Yu’s world views shattered into pieces: What the heck is an Omega?!

Qiu Yu, who knows nothing but fighting, eventually decided to become an anchor for a full-dive game—not only could he use his battle techniques to make a living, but he also didn’t have to brave leaving the house and meeting people—it was the perfect job.

However, in his first-ever broadcast, he shot an arrow straight through the heart of the e-sport circle’s verified no.1 god of war.

Mu Feibai touched the place above his heart, the corner of his mouth hooking up: Interesting… Come play professionally.

Qiu Yu rejected him: social anxiety, not going, see ya.

…And then he was sold off by his live-streaming platform to play for a professional team.

Qiu Yu: This was different from my plan!

Mu Feibai: You shot an arrow straight into my heart… baby, you still want to run?
