A Time Traveler's Hundred Days' Adventure

In the mysterious town in the parallel universe, the speed of time flow is different from that in the outside world - one day in the outside world is equal to about one year in Time Town. The town is wrapped by a "time barrier" that prevents ordinary people from entering. Only the selected "time guardians" and "time walkers" can cross the barrier. The center of the town is a clock tower. The big clock on the top of the clock tower is the core controller of the Gate of Time. Below the bell tower is the Time Library, which is run by Lao Wu.
