The weakest profession of dragon tamer? I contracted a cold school beauty

【Easy + Superpower + Single Female Lead + School Beauty + Oriental Dragon】
In the era of spiritual energy revival, awakening has become something that everyone must experience.
Su Chen awakens the strongest and most useless dragon tamer talent at the beginning.
Dragon taming, what a powerful talent, but what about dragons? The country won't give it to you!
Fortunately, the treasure chest system was awakened, and I opened the treasure chest to get rewards. I contracted the first dragon in my life, but I never thought that the dragon turned out to be the cold school beauty Chu Muxue.
When I first contracted, it was a proud little ice dragon. Over time, the school beauty Xiaolong said...
Su Chen, my mother is the Ice Dragon, and she said she wants to be your contracted beast.
Su Chen, my sister is the Life Dragon, and she wants to be your contracted beast with my mother.
Su Chen, my father is the Dark Dragon, and he said that as long as you contract him, he will bring my mother and sister with him.
But my grandfather disagreed. He said that he was the father of the Dark Dragon, and if you contract him, he will bring the entire dragon clan to join you.
From then on, a most useless dragon tamer led countless dragons to sweep across the world.
As a dragon tamer, it’s not too much to have more than 100 million dragons, right?
