"Whirlpool Clash" 

The water barrier was also created from the surrounding water, but it might be because it was not used to create an offensive attack, which was why it could work. 

The two people immediately switched roles and after the glasses man manipulated the water barrier to carry the group to avoid the whirlpool, it was the mermaid's job to face the whirlpool. 

Time was ticking and they were close to being teleported away, but the whirlpool was also already so close to them. 

Without someone manipulating the water barrier to resist being sucked into the whirlpool, they would have been sucked into the whirlpool. 

Then, they would either drown or be torn apart by this unusual whirlpool. 

The whirlpool not only felt like a strange one but it was also more deadly than an ordinary whirlpool because this one had blade-like features inside,  which could tear apart anything that entered the spiral.
