In The Zombie Shadows Chapter 83

After completing the deal with the killer whale, Jake Qi said goodbye to Aisha and others and set off back to District 11.

The killer whales and dolphins were sent to the shore. The baby killer whales and dolphins dived underwater and found a dozen scallops over half a meter long, wrapped them in seaweed and gave them to the kittens.

Jake Qi taught them how to weave straw ropes and net bags. The little guys were very smart and could draw inferences from one example to select tough seaweeds and weave them into several good fishing nets.

Adult killer whales and dolphins use their talents to hunt, and the little guys can't help much. They simply use fishing nets to catch scallops and sea clams from the bottom of the sea.

They weave mutated seaweed into their fishing nets. These mutated plants that feed on shellfish and arthropods will actively capture prey and bring a fruitful harvest to the little guys.
