There was a short distance between the reef and the sea. Although waves kept hitting it, half of the hole was still empty, otherwise He Siyang would already have been drowned.
Gu Ning and Leng Shaoting observed the reef for a while first to see whether it was different from others. They soon noticed that there was a separate rock placed on it. It was supposed to be the entrance of the hole, but He Siyang closed it with a rock to prevent others from finding him.
The entrance was wide enough for a person to get in, and the rock placed on it was as big as a 20-inch suitcase.
Ordinary people probably wouldn't notice the difference, because they weren't able to see the hole under the rock.
Thanks to the two wolves, Gu Ning had an excuse to point the difference out.
"Why don't we move the rock away?" Gu Ning proposed.
"Sure, let me do it," Leng Shaoting said.
