My skills are enhanced a hundredfold, who dares to say that I am a weak mage!

Gu Yi changed his job to a hidden profession [Elemental Mage], but was told that the mage was too weak in the early stage and had no strength at all?
Can he only level up by killing monsters with other teams?
Talent skills activated! Every level up will give you an amplification opportunity, and you can designate any skill to be strengthened a hundred times!
[Fireball spell strengthened successfully → forbidden spell-World-destroying fire rain]
[Lightning spell strengthened successfully → forbidden spell-Purple Lightning Thunder Dragon]
[Frost spell strengthened successfully → forbidden spell-Extreme Freeze]
[Elemental Tribulation strengthened successfully → forbidden spell-Elemental World-destroying Light]
Moreover, the already strengthened skills can be strengthened again!
The legendary world-destroying spell! All the super spells that can destroy order appear in Gu Yi's hands!
Since then, Gu Yi has been invincible from the start!
Others need to form a team to pass the dungeon, but he can easily play it alone with full difficulty!
Others may not be able to take down the BOSS even if they are cautious, but he can kill it instantly with just one skill!
Others can only level up 1 level a day, but he can level up 10 levels a day by playing alone!
Gradually, everyone found something wrong.
"What's going on? Isn't he a mage? How can he be so strong!"
"Could it be that this is a once-in-a-million-year genius?"
For a time, various forces competed to win him over, and even the Daxia government came out directly, just asking Gu Yi to join, and the conditions were arbitrary.
The Abyss even regarded Gu Yi as a major concern, and wanted to kill him completely at all costs!
A few years later, Gu Yi stood at the top and looked back: "I have always said that I have never been a genius, I am a monster among geniuses!"
