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.

I Have Awakened The Deduction System

It wasn't like there weren't cases of people killing all over the country, or rather, it was the standard for top-notch experts.

Not even a single expert will be tainted by blood.

"Understood!" The ghosts and deities were already thirsty.

The Sea Kingdom was completely erased from the map today. The land was dyed bright red, and the bright red land could still be seen a hundred years later.

The Central Land had a large population, and the combined population of the various major forces could be more than ten billion. If they wanted to increase the population, they would have to live a comfortable life and have sufficient food.

With the support of spells, ordinary natural disasters could not destroy agriculture at all. Even if they were destroyed, there were spells to produce food, and it would not be a problem to produce dozens of crops in a year.

Cultivators lived for a long time, and dynasties were often peaceful for thousands of years.
