Chen Xi, a top student at Yancheng No. 1 High School, possesses an extraordinary ability to remember everything he sees, known as hyperthymesia. His deskmate, Lin Fan, mysteriously disappears on the tennis court, and the entire world begins erasing all traces of his existence. Only Chen Xi, thanks to his hyperthymesia, remembers Lin Fan. The school beauty, Zhang Wanyi, reveals that Lin Fan was devoured by the Black Tower, which appeared 50 years ago. Zhang Wanyi is actually a supernatural being who introduces Chen Xi to the extraordinary world. The Black Tower is the enemy, and impostors steal identity cards from supernatural beings, who rely on these cards to obtain their abilities. When impostors launch a surprise attack, Chen Xi unexpectedly awakens the Second Sequence: Farmer, gaining the ability 'All Are Equal' and obtaining a mysterious tennis-ball containment artifact.
