Global Class Change: You Said Beast Taming, So Why Did You Contract an Ancient...

The game merges with reality, and countless races stand among the stars. Humanity enters a chaotic era and builds a great defensive line through an era of universal class advancement. At the Class Awakening Ceremony, top student Xu Kun, a high school senior, awakens the lowest-of-the-low F-rank class: Beast Tamer. His starting beast is a dull yellow snake with no offensive ability, and the entire crowd laughs at him.

The Classic of Mountains and Seas: Ten Fiendish Beast Contract scroll in Xu Kun's mind suddenly opens! By collecting specific resources, he can break through rank barriers, trace ordinary beasts back to their mythic origins, and unlock the evolution of the Ten Fiends! [Dull Yellow Snake] → [D-rank Blackwater Spotted Python] → [SSS-rank Chaos Heaven-Devouring World Serpent]... While everyone else carefully explores low-level secret realms, Xu Kun and his young Ten Fiends strip every dungeon bare, even stealing the core treasuries of villainous guilds and Abyssal Lords from afar.

From soloing a violent bear in Linjiang City to repelling a stampede alone at a wilderness fortress; from crushing the nation's top geniuses in the national league to standing guard at the Starry Sky Fortress, blade in hand. When the Bashé swallows the heavens, the Great Peng splits the skies, Taotie devours worlds, and the Nine-Headed Serpent commands water and fire, Xu Kun's Ten Fiend army shakes the cosmos. One day, foreign gods tear through the barrier of the stars and descend upon Earth, ready to reap humanity.

Instead, they run straight into Xu Kun, who has been waiting for them at the starry defense line, bored out of his mind, with ten colossal mythic beasts of the Great Wilderness at his side.

“I've waited hundreds of years for you. You're finally here.” Xu Kun smiles!
