Pikachu

Ye Fan was transmigrated to a world where everyone was a beast tamer. As the demonic beasts rampaged around the world, humans were forced to build walls to protect themselves while the beast tamers fought the demonic beasts.
As the day of enrollment got close, Ye Fan only had a pet beast, the Cute Sparrow, with him.
“A Cute Sparrow? Don’t you have a better beast? You’re helpless.”
“That beast’s potential is just too bad. Even if it evolves into an Iron Eagle, it can only reach the Intermediate Grade 1.”
“You’re trying to get into the academy with that? Dream on!”
He was mocked and laughed at, but Ye Fan remained calm as he looked at the system’s menu.
“Hidden evolution path.”
“Divine Path: Infinite evolution potential. King Grade achievable.”
His sparrow started to evolve into a Golden Scale Eagle, then the Illusion Feather, the Nine-heaven Roc, the Flaming Phoenix, and finally, the Garuda.
“The f**k? Are you telling me that’s a Cute Sparrow?”

I've Activated The Hidden Path of Beast Evolution

The Duke of Hellfire directly evolved into the Inferno Tyrant, a high-level Rank-7. There were no other changes. The next evolution stage was the Inferno King.

Seeing this, Ye Fan smiled in satisfaction. The fox and tyrant had both advanced by a large level, he looked at the new skills.

Unlocked Talent: Inferno Rebirth. After receiving the death attack, it can be reborn from the flames and return to its original form, but its strength is only half of its original state. After activating this talent, it can only be activated again in 20 days. 500 points of evolution.

This was a very practical talent that could complement the self-destruction skill. He was no longer the same as before, and he usually would not encounter situations that were difficult for him to deal with.
