I Have an Infinite Merit System

Accidental death obtains the merit system. From then on, Yang Xiu completes various time-travel tasks under the arrangement of the system. The time-travel starts from the classic fantasy world. It does not delay the plot, jumps when it is necessary, and the plot tends to be refreshing. ... In the haze, Yang Xiu heard a "ding..." Sound. "Congratulations to the host for obtaining the merit system. By traveling through various worlds and completing system tasks, you will gain merit points. Going to heaven and earth, time travel will no longer be a dream. Friendly reminder, if the merit points are too low and you lose the blessing of merit, the host will be recalled by the gate of reincarnation." "The time travel begins, this world's mission: save this world!"
