A mediocre and extremely poor college graduate, his favorite hobby in life is squatting in a corner and pumping mobile game cards. However, when he was all purple for ten times in a row, a Q-version cute creature who claimed to be "the world's only designated 'Koi' administrator" fell from the sky and kicked him into the world of infinite chaos.
In this world, pirates' cannonballs can blow up teaching buildings, ninjas' shurikens can do pedicures, and onmyoji's shikigami rush to deliver food. The "golden finger" given to Zheng Qian is that as long as he complains hard enough in his heart, the real lucky value will appear on his head, and the "reverse card drawing" mechanism will be triggered: the more non-chiefs he is, the higher his luck. He won "SSR: The right to use Luffy's rubber arm", "SR: Inuyasha's pants", "R: Spirited Away's Boiler Grandpa's autographed briquettes" and other random things. Every time the trump card is revealed, it will bring unexpected funny miracles.
He thought he just had to eat and wait to die, but his ex-girlfriend Su Yao became a star member of the hostile force "Book Traveler Alliance" and brought a group of new and old lovers to hunt him down. The reason was "Aren't you the loser who drew cards back then?" In order to survive, Zheng Qian was forced to embark on a hilarious path of "making trouble, drawing cards, and fighting wits and courage with his ex-girlfriend and her followers" in order to survive. He used the luck of the koi carp to trick the crying empress, teamed up with the poisonous tongue system to tease the Akatsuki organization, and even landed the C position in the "Fantasy Male Idol Draft"... He slapped people in the face like crazy along the way, revealing the real source of the world's loss of control - it turned out that the power of the koi carp was not an accident at all, but the real secret of his breakup with his ex-girlfriend.
