The Ultimate Series: I Signed In as Wang Dadao’s Brother

Wang Dayu, Wang Dadong’s older brother, awakens the “Sign-in System” before Dadong enrolls at KO One. By checking in at special locations, he can earn rewards such as combat power, skills, and items. Knowing the plot of the Ultimate series, he initially wants only to quietly improve his strength and protect his family. But System missions and the pull of the story gradually draw him into conflicts spanning different time periods. In the Golden Dimension, he secretly helps Dadong, Ding Xiaoyu, and Wang Arthur, changing the balance of power in the early days of KO One. He travels to the Iron Dimension to help Xia Tian master the power of Ghost Dragon and foil the Yehenala family’s schemes. Then he heads to the Silver Dimension, sees through Xiu’s identity, and joins forces with him to stop Dong Zhuo from conspiring with the Demon Realm. As the Demon Realm’s forces across the dimensions join together, Wang Dayu rallies the forces of justice from the Golden, Iron, and Silver Dimensions. With his peak combat power and “Dimensional Synchronization Technique,” he joins Dadong, Xia Tian, Xiu, and the others to destroy the core of the Demon Realm’s ultimate boss and close the “Devouring Gate.” After the battle, the System goes dormant, and Wang Dayu gains “Free Passage Between Dimensions.” He becomes a guardian of the dimensions, occasionally appearing to spend time with friends and family. Wang Dadong, meanwhile, grows into the new pillar of the Golden Dimension. The legend of the brothers’ bond and their protection of the dimensions lives on in the Ultimate series.
