Soon, a large black skeleton army gathered behind Skeleton 1.
The sheer amount of heads emitting green light in the seawater looked so strange and terrifying.
Of course, Su Yu also used the Eyes of Duplication to duplicate the Skeleton Summoning Skill for himself.
However, as this was Skeleton 1's intrinsic skill, the power and number of summons of this skill were greatly reduced in Su Yu's hands.
Then, Su Yu began to control the Ghost Ship. He put Skeleton 1's skeleton army into the cabin.
Su Yu sent Skeleton 1 into the driver's seat.
Some parts of Skeleton 1's body had already turned silver. Su Yu decided to hunt a few more Silver sea beasts and use them to upgrade Skeleton 1 into Silver Rank Skeleton General.
As for whether it could break through the potential barrier in advance and break through to a gold skeleton without the help of the Rank Up Tower, that would depend on whether Su Yu could find some special items.
