Global gamification, professionals become mainstream.

A mortal who fails in his job transfer has only two choices: either go to the underground world and become a miner, or exchange fifty years of his life for the worst job transfer book.

Li Du chose the latter, changing to the worst profession and a skill that would cost him his life to deal damage.

As a result, Li Du discovered that his talent was life absorption! Killing monsters would increase his lifespan!

So Li Du laughed. You said I don't have many years to live?

I killed 1,300 monsters, and my life span increased by three years. I killed 10,000 monsters, and my life span increased by more than 20 years. If I killed a million or tens of millions of monsters, how much more life span would I be able to add?

The more you kill, the more you add.

When his lifespan is long enough, Li Du can even exchange for god-level professions, forbidden spell skills, and god-level equipment...

When Li Du looked back again, he found that he had already become a god.
