- Description from Novelupdates

Superpowers descended upon the world. This was a world where everyone awakened to superpowers.

Some people awakened to abilities at the lowest F rank. They could only work the most difficult jobs for their entire lives. Meanwhile, some people started off with S rank powers and skyrocketed to fame.

In this age where talents determined everything, Ling Feng awakened the clone ability, which was ranked second last in the F rank powers.

The crowd mocked him, “That is one of the most useless talents. After one awakens this ability, they can create a clone of themselves. However, their strength is halved in the process. Aside from running errands and making deliveries, it is useless.”

However, very soon, Ling Feng discovered that something was off. That was because his talent could level up from the lowest F rank up to the SSR rank! He had unlimited clones and unlimited evolution!

Many years later, half of the superpower users in the world were Ling Feng’s clones.
