Introduction to shark upgrade methods:
Equip pets and try to survive as long as possible, so that the number of gold rushes will increase. You can get a lot of points to increase the shark upgrade speed. If you have a lot of diamonds, you can buy a royal scepter and a bone belt, which will greatly increase the growth value. But after the shark reaches the max level, these two things bought with a bunch of diamonds will become decorations, so friends should think carefully before buying them.
