You Proposed Breaking Off the Engagement, but Why Are You Crying About the Extermination of the Clan?

Starfall Era, apocalyptic wasteland. Superpowers are awakened in the killing, and humans build a new class on the ruins. Ye Qingxuan, the former genius of the Ye family in Rock City, awakened his S-level potential at the age of twelve and attracted much attention. He even made an engagement with Su Wanqing, a genius girl from the Su family. However, an accident occurred when he was fifteen years old. His affinity was completely lost, his level plummeted, and he became an F-level waste that everyone laughed at. He was also judged to be the most rubbish profession - card master. At the 18-year-old coming-of-age ceremony, my cousin Ye Yunfeng and Su Wanqing broke off their engagement in public. They were extremely humiliated: "The garbage station in Black Rat Lane will reward you. You will never starve to death." With the whole hall laughing, Ye Qingxuan tore up the marriage contract, leaving only a cold smile. That night, the gray crystal core in his father's relic finally woke up and was bound to the [All Realms Card Book System]. In this world, superpowers absorb the energy of crystal nuclei, and he collects the crystal nuclei of all things and generates exclusive cards! Zombies, alienated beasts, abyss dependents, descendants of ancient gods... Are all in his collection! Deck bonding, unlimited synthesis, star upgrade and evolution! While others are cultivating a special ability, their deck already spans [Immortal], [Mechanical], [Cthulhu], [Myth]... One person is a legion! Three years later, a horde of beasts besieged the city, the genius shed blood, and the end came. Ye Qingxuan stepped out of Black Rat Alley, with a torrent of cards behind him. He looked at the pale-faced Ye Yunfeng on the high platform, at the complicated-looking Su Wanqing, and at the coveted "Reaper" civilization beyond the starry sky, and smiled slightly: "There are still many empty spaces in my card book." "I'll accept your crystal core."
