Ye Liu and Xiao Hua looked at each other but they still nodded and then plunged into the sea, since they were mers, their strength was not as good as compared to Yu Dong which was why they were scared of drowning after losing their breath.

Ye Liu and Xiao Hua were shocked when they heard Yu Dong's voice, they did not expect that she will be able to talk under the water but they still were a bit suspicious, after all, how was it possible for humans to breathe under water? But they still took a tentative breath until Yu Dong's eager eyes and then they were surprised——

Because they could really breathe under the water!
