National Beast Control: I Rely on Reading Books to Contract with Sacred Beasts

[High martial arts master] [System] [Reading the book will increase the system score] [No heroine] Yun Jinghong transmigrated into the world of beast masters. The system searched for him for eighteen years and finally found him. The one-hundred-thousand-word book of beast-controlling miscellany is a plug-in given to him by the system. As long as he reads it, he can redeem various elixirs and help him upgrade his contract. When others make a contract, they can only wait eagerly for a suitable beast master, but Yun Jinghong is different. He only needs to choose the one with the best potential.
