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?”

Du Kang frowned. It was one thing for the vampire to be powerful, but what was wrong with this dragon pet? It clearly had the aura of a Rank-7, but its strength was not inferior to a Rank 8.

He suspected that Ye Fan had some unspeakable secret, otherwise, how could he be so powerful when he was not even twenty years old?

Under everyone's unbelievable gazes, the two dragons fought again. Both sides were dragons, so the dragon might and dragon breath they displayed were useless against both sides.

The only things that could release damage were powerful physique and elemental skills.

The Rotten Flesh Dragon had a poison skill that could spit out venom. Its sharp claws and teeth were poisonous, but unfortunately, the enemy it faced was the fully resistant Firmament King. The Firmament King had resistance to all these effects.

Moreover, he had a perfect physique and the same vitality as a Legend. No poison could harm him.
