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.

"The reason why I attacked him just now was only that you have been my Master for many years. It doesn't mean that you can order me around!" Wei Lin slowly lowered his raised hand and said coldly.

"What do you mean? Is it that your wings have hardened now? You don't even listen to the words of this old patriarch..." Wu Ji patriarch was furious and shouted coldly.

"It seems you're still unclear about the current situation!" Wei Lin immediately interrupted Wu Ji patriarch's endless anger. A powerful aura burst out of his body and instantly enveloped Wu Ji patriarch.

"What do you want to do?" Wu Ji patriarch shivered at the chill and stammered.
