Sailing, Starting with a Fire on Mary Joa

Before I traveled through time, I was an ox and horse, and after I traveled through time, I was still an ox and horse. So didn't I travel through time in vain? It's so unbearable for my aunt and uncle! We already have a system, so who can still be considered a human being? Of course I choose not to eat beef! Then set a small goal, first kill a few dragon pigs to add to the fun, and then burn Mary Joa! Woohoo take off!
