After establishing this fact, they knew which fish to avoid getting close to to avoid being injured and infected with the zombie virus and which to attack randomly.
Since they were afraid of the zombie virus spreading through the water and infecting the good fish through their injuries, their attacks included a strategy to slowly lead away the mutated fish and isolate them from the zombies.
Some people dealt with the zombies, while others fought the mutated ones. With every mutated fish killed, it disappeared into Chu Miao's stream in the soul ring.
She put it straight in the stream because that stream had spiritual spring water that could help to purify any zombie virus that might have slipped into the fish by mistake. Also, it could nourish the meat and when given to the team members, it would be more beneficial than before because of absorbing spiritual energy.
