"Is it okay to leave them there, prof?" asked Thomas as he and the others dived deeper into the ocean. All the new members, Julian and Vega, were with him, but not Carl and Miku. They were still above.
"It's okay. Carl and Miku have their own practice."
Thomas looked up one last time before following the others to go deeper into the ocean.
Meanwhile, Carl and Miku continued their morning practice.
"Good, Carl. You can last more than ten minutes this time. That's good progress." Miku praised him.
Carl showed a grin even though his body was a little tired. He had to swim while controlling his shield. "How about going deeper?" He suggested. He also wanted to go with his friends.
"We'll go ten meters deeper for practice before following the others. How about that?" She suggested something else.
Carl looked down and thought ten meters was easy. "Okay."
Thus, they swam deeper. But suddenly, Carl felt more substantial pressure, and it caused him a little difficulty taking oxygen.
