“Boss. Aren’t you too greedy? You are selling this husky mutt for 500,000?”
A cute girl in a ponytail held a husky puppy, whose eyes looked exceptionally wise, in her arms as she glared at Lin Ye. Her gaze was accusing him of being a dishonest trader.
Lin Ye explained, “Miss, I have to formally inform you: this is not a husky mutt.”
The girl retorted, “Don’t you dare trick me.”
“I’m serious. It has the bloodline of Cerberus. Its potential is limitless.”
The girl was stunned by Lin Ye’s words. 
After pondering for a moment, she realized that what he said was absurd. Agitated, she yelled, “Are you sure? I don’t believe it!”
Lin Ye gestured at the husky in her arms as he said, “Little fella, get down and show your future owner what you can do. Go!”
“Woof!”
The girl shrieked in horror as she witnessed the little husky spit out a fireball the size of a fist.

Many years later, Lin Ye has crowned the Father of Beast-taming of the Blue Planet. When he was interviewed, he said forlornly, “It all started with a husky mutt.”
At the same time, in a mansion, a gigantic red dog with three heads sneezed. Then, it barked at the television before it.
“Woof!”

I Made Beast-taming Widespread Across The Globe

"Everyone, don't worry. It's sold in the evolution herb dojo."

He looked at Yang Wei as if he was looking at a fat sheep.

"It's basically the same price as beasts, but the price of evolution grass of the same quality won't fluctuate like beasts because of individual differences."

"My Mysterious Water Turtle is of purple quality. At that time, I bought it for 300,000 credits. Is the evolution grass priced the same?"

"The price of purple-quality beasts is between 100,000 and 50, so the price of the evolution grass only needs 100,000."

"The price of orange beasts ranges from 500,000 to 1 million, so the price of their evolution grass is 500,000."

In the end, Lin Ye said this to Su Qingqing.

"It's the same for the other quality."
