"Those are the sea folks! The sea folks are invading! Hurry up and close the gate!"
A fierce battle was taking place at the floating city's main entrance.
A few mermaids had wanted to attach themselves to the cargo ships to hitch a ride into the floating city. Unfortunately, when the guards were inspecting the cargo on the cargo ship, one of the mermaids did not hide properly and revealed her tail; the guards discovered them.
After they were discovered, the gold-tier mermaids decided not to hide anymore. One of the mermaids threw a harpoon that hit one of the guards, who was then lying on the ground, bleeding non-stop. The remaining three guards frantically turned the valve outside the gate. However, one person was missing, and the mermaids were wantonly attacking the surrounding cargo ships, causing those cargo ships to try to enter the city frantically. Some of the enormous cargo ships were stuck at the gate, preventing the gate from closing properly.
