"Fantasy - Beast Taming - Transmigration - Growth - Plot - Play the pig to eat the tiger"
The moment Fang Ai opened his eyes, he found himself transmigrated to the Xuanling Continent, in Wuyac Village, a place crawling with big shots. He was supposed to form a contract with a light-element divine beast, the Sacred White Unicorn, and enjoy a smooth path to success. But fate played a ridiculous trick on him: an accident led him to contract with the lowest-ranked dark-element demon spirit, the Trickster Demon!
The sharp claws of the Darkgold Winged Tiger King carved a path through the brambles for him, while the roar of the Eastern Sacred Canglan Dragon sent a thousand troops fleeing. The Sacred Vine Ball's ferocious power embodied the true art of brute force, and the snow-white king beast's ice element summoned the most extreme winter... But the very Trickster Demon everyone had looked down on at first was hiding a secret that could overturn the entire Xuanling Continent!
Leading his demon spirits to the top of the Xuanling Continent, Fang Ai proved to the world through sheer strength: there are no useless demon spirits, only useless spirit tamers!
As the Trickster Demon's shadows mingled with the holy light of the Eastern Sacred Canglan Dragon, a demon-spirit tide sweeping across heaven and earth was only just beginning...
