What task does DNF Niu Tu do to get out?

It's best to do the hidden task first. It is best to complete all major tasks at this level. The map of the mechanical cow is to be opened from the clay pot. It's a waste of money to open a boken doll, a clay pot doll and the king of cans. If you are lucky, you can open the tri-red crystal once and drive directly to the pottery doll. After that, you will be allowed to go to Billmark Imperial Test Site. You can take 10 soul +30 black crystal to Norton to get immune capsules, and you can enter the mechanical cow map every time you enter.
