I'm Only 10 Years Old, Let Me Fight Back And Be Reborn As A Beast?

I was shocked, I traveled through time and came to the world of cultivating immortals, and the Rebirth counterattack system was eight years early!
【You are reborn at the age of eighteen. ]
[In your previous life, when you were thirty years old, you accomplished nothing. After giving up your obsession with cultivating immortals, you explored the world of mortals. Before you died, you finally awakened to the divine beast-controlling physique, but it was too late. 】
【In this life, you must seize the opportunity, embrace the future, and let all regrets disappear. 】
【You are the man who wants to become a true beast-controlling immortal. 】
[Rebirth mission: Contact five different pet beasts, activate the divine body of all spirits, understand the natal magical power: pet travels around the world, and unlock the natal spiritual pet: Somersault Cloud. 】
Lin Ang, who had just figured out that he had time-traveled into a child and was in a difficult situation, fell into deep thought.
"The system found the wrong person?"
"Or did I time travel to the wrong person?"
"I'm only ten years old, what the hell is it to be reborn to eighteen!"
"This system is unreliable!"
...
Many years later.
“Do you know Lin Ang from the Beast Control Sect? I heard that he has many pet beasts, but few people see him.”
“The Lin Ang who stays at the top of the mountain all day long, obsessed with farming and drinking tea, and does not do his job, but always comes out on top in every competition and trial?”
“The one who says ‘loves to laugh’ Boy, isn’t Lin Ang so unlucky? Even after listening to his words, I couldn’t even break through the third level of Qi training.”
As for why he is so strong, it is purely because of his hard work.
It has nothing to do with him petting animals and loving traveling.
