Time travel is a very common thing.
There are many ways to travel through time, including being struck by lightning, drowning, choking on drinking water, choking on eating, and even traveling inexplicably while walking. Therefore, traveling through time is a very common thing.
In recent years, the number of travelers has been so large that the people who manage each dimension, or gods, are astounded, so the Travelers Association was established.
The rules are as follows:
1: Only travelers who have completed the tasks assigned by them can enter and exit each world.
2: Travelers must accept some commissions regularly. In return, travelers can exchange items for items with points earned from completing the commissions.
3: Travelers have the obligation to deal with stowaways, and the rewards are rich.
