My Unreliable System

Fu Hui, an ordinary college student, unfortunately fell into a valley and survived the catastrophe and obtained the system. I happily started my first time travel, but found that the situation did not seem to be ideal. "System, did the time travel succeed?" "Ding, the system is being updated, please wait patiently, the remaining time is: 2 days, 23 hours and 48 minutes." . . . This is the beginning of Fu Hui's story of traveling through various strange worlds.
