Job Transfer for All: You Agree to Control the Beast, and You Contract with the Ancients

The game integrates reality, with thousands of races populating the sky, and mankind entering a great defense line in troubled times where everyone changes jobs. At the job transfer ceremony, Xu Kun, a senior high school student, awakened to the most obscene F-level profession - beast master. The initial beast was a khaki snake with no attack power and was ridiculed by the audience. The "Book of Mountains and Seas: Contract of Ten Evils" suddenly opened in Xu Kun's mind! As long as you collect specific resources, you can break the grade barriers, trace the origins of the myths of ordinary beasts, and start the evolution of the ten evils! [Yellow Snake] → [D-level Mysterious Water Spotted Python] → [SSS-level Chaos Heaven-Swallowing Snake]... While others were still cautiously opening up low-level secret realms, Xu Kun had already taken his ten evil cubs to plucking hair in major dungeons, stealing the core treasury of the villain guild and the abyss lord. From Linjiang City killing the violent bear alone, to the Wilderness Fortress alone defeating the beast wave; from crushing hundreds of geniuses in the National League, to the Starry Sky Fortress crossing the sword. The snake swallows the sky, the roc splits the sky, the glutton eats the world, the nine babies control water and fire... Xu Kun's ten evil legions are powerful in the stars. One day, the alien gods will tear apart the starry sky barrier and descend on the earth to harvest the human race. But he ran into Xu Kun, who had been waiting boredly at the starry sky defense line for a long time with ten wild mythical beasts. "I've been waiting for you for hundreds of years, and it's finally here." Xu Kun smiled!
