This Ye Jian

Since it was the Snow Region Brigade's training skerry, how could it not have any sea defense? Also, the place they were going to was the unit's training room.

Ye Jian didn't move anymore. She followed Big Shark's steps closely. She didn't stop until she was about five meters away from the end of the reef. There was a natural cave.

Big Shark stepped on the reefs that were filled with conch shells. Ye Jian followed behind them and walked into the cave. It was like walking into the hinterland of the skerry.

When she walked in, she realized that there was something special about the cave. The entire cave wasn't formed naturally. It was artificially built. The cave entrance was low. When she walked up, she could hear the sound of seawater. However, she didn't see any seawater pouring in.
