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?”

Dark-type Magical Beasts were very special among Magical Beasts. There were very few Magical Beasts that were excluded from pets, and dark-type Magical Beasts were among them.

The reason was that if Beast Tamers contracted a dark-type Magical Beast, Beast Tamers with weak minds would be contaminated by the dark attribute of the Magical Beast, causing their emotions to become chaotic and depraved. Because of this, Dark-type Magical Beasts were also known as the symbol of evil.

However, at the same time, dark-type Magical Beasts grew quickly and their strength increased very quickly.

Beast Tamers who contracted dark-type Magical Beasts were stronger than ordinary Beast Tamers.

It was precisely because of this that even though many Beast Tamers clearly knew the danger of dark-type Magical Beasts, they still chose to contract them.

"Peak Rank-3. This strength isn't too difficult to deal with."
