Highlights
Zhang Yu moves into the Lin Mansion after his father's second marriage, gaining five older step-sisters. He encounters initial hostility, particularly from Lin Wanqing, and activates the 'Infinite Lucky Card System' which rewards him for increasing his sisters' favorability.
Zhang Yu uses his system rewards, like the 'Hundred Battles Unbeatable Card', to gain favor with his sisters, notably by buying them gifts and excelling at mahjong. He gains medical skills and an 'unlimited money-making skill' by spending time with them. He also uses a 'bankruptcy card' to neutralize a threat to his fifth sister, leading to the collapse of the Fuxing Group.
Zhang Yu's insightful decisions, guided by his 'Prediction Card', secure profitable land deals for the Lin Group, leading to his appointment to the board of directors. He faces opposition from his second uncle, Lin Qingming, who attempts to frame him. Zhang Yu uses his 'secret card' and 'debt collection card' to expose Lin Qingming's corruption and manipulation, leading to his arrest and Zhang Yu gaining his shares.
Zhang Yu's father is involved in a car accident. While investigating, Zhang Yu discovers that his father's marriage to Mrs. Lin is a fake, arranged to protect him. He learns of a powerful figure, Jiang Daqiao, who targeted his father due to a past grievance involving identity theft.
Zhang Yu continues to use his system to navigate challenges, acquiring a 'secret card' to investigate Long Tianjiao's secrets and a 'property card' to claim a valuable Beijing courtyard house. He also uses an 'annihilation card' to eliminate Chen Yuliang, who was involved in the attempt on his father's life. He uses his resources to help his second uncle, Long Qinhu, get reinstated and regain control of a military industry project.
Zhang Yu travels to Beijing and encounters the influential Long family. He learns of his grandfather's connection to the Long family and a past debt of gratitude. Old Master Long attempts to matchmake Zhang Yu with his granddaughter, Long Tianjiao. The sisters follow Zhang Yu to Beijing, and they find out about the fake marriage of their parents.
The sisters discover that their mother's marriage to Zhang Yu's father is a sham, but their bond with Zhang Yu remains strong. They support him as he expands his influence. The system undergoes a major upgrade, unlocking all cards and granting Zhang Yu the 'SSR upgraded version soldier card,' which gives him global power and control over 50,000 people, signifying his rise to international prominence.
