Su Suisui was born with divine strength and was always tearing off roofs in Qingyun Valley. Her old father, Su Laojiu, took out five aged IOU notes and coaxed her to go down the mountain to collect debts and gain experience. Carrying her bundle and shouldering a giant bow, Suisui embarked on her journey, heading successively to the Martial Realm, the Demon Realm, and the Immortal Realm. Facing martial arts expert Lin Qingshuang, Demon King Pang Qinglian, and Immortal Realm formation master Zhen Xuanling, she showed up with the IOU notes to collect debts, causing quite a few ironic and comical funny events. It turned out that the IOU notes were all left behind when Su Laojiu saved the three of them back then, and the three big shots showered her with generous gifts upon seeing the notes. Suisui refused valuable treasures, single-mindedly wanting to complete her training, while two factions of people secretly protected her from behind, continuing to search for the remaining debtors.
