Mimizuku to Yoru no Ou - Commentary - Hiro Arikawa

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.

Son of the Senior Chancellor, Luo Wei, loved the wrong person in his past life. This mistake caused his entire family to be wiped out, and in the end, he was cast down as a pleasure slave, and died in the wilderness during the depths of winter.

Somehow, the heavens did not give up on him and gave him a second chance at life. He believed this rebirth was only meant for atonement, and not love. Yet, as he plotted his vengeance, Luo Wei quickly realized that passion would again be his fatal downfall.

The once emperor, the lover from his past life, his beloved in this life, and an opposing empire’s monarch who is doomed to love him, who is supposed to be good for whom?

And who is supposed to hurt whom? A hero chasing after a dream, an empire of a thousand years, a kingdom stretching across the known lands, all flashing before the eyes like a mirage. Is it worthwhile to trade a hundred years of my loneliness to give you a single lifetime of joy?
