Description

The abyss is coming, and the Blue Star changes!
This is an era of professionals. Everyone can get their first skills and become professionals when they reach adulthood!
Lin Yi obtained the fireball technique and became an ordinary magician.
At the same time, an SSS-level talent was awakened: Gift of the Gods!
Effect: You can gain 1 skill point every second!
Others can only get single digits of skill points to upgrade their skills in one copy.
And Lin Yi can get one for free every second!

Then, ice system, wind system, thunder system, light system, dark system, space system, time system...
Countless basic spells are in Lin Yi's hands, and they can be upgraded into forbidden spells at the speed of light!
A few years later, the Demon Lord of the Abyss came to Blue Star——
But he saw Lin Yi sitting on the throne of the Supreme Demon Palace, overlooking all living beings!
Lin Yi: "How about you choose a way to die?"
