Chen Shu traveled to a parallel world of beast control as soon as he woke up. The class was all about beast control knowledge, and it was also bound to a god-level selection system - you can get rewards when you make choices! This world is full of extra-dimensional space gates and ferocious beasts. Beastmasters contract with alien beings to protect humans. They have a very high status and can awaken their beast-taming talents at the age of fifteen. With the blessing of the system, Chen Shu cultivated a group of strange beasts that subverted all three concepts, including a slime that could kill a giant dragon, a husky that used elemental skills to blast a phoenix, and a mysterious partner who mastered the power of space. Each beast was so outrageous that it broke common sense. Relying on the creed of "Beast Controlling Never Talks About Science", he led this group of bullshit Controlling Beasts to sweep away the Controlling Beasts.
