Chapter 369 clam

There is a kind of clam in the East China Sea. When it is hungry, it will swim to the shore. The two shells open, and a small crab crawls out of it, with a red line tied to the clam. The little crab swims within a few feet of the clam, hunts automatically, and returns to the shell after being full. If someone dives into the water and cuts the red line, clams and crabs will definitely die.
