Logically speaking, before confirming the value of a fish, there is actually no need to expend effort in hunting it, as it might turn out to be a waste of time and energy if the fish is not valuable.
But Chu Mingcheng was in a special situation, as he had an "external cheat."
Although he had not identified the exact species of the fish, after catching one just now, the High-quality Atlas had gained a little experience value.
This indicated that the fish he caught was extremely valuable and belonged to the category of high-quality fish.
And since the fish here looked so similar to the one he had caught, only much larger, under normal circumstances there was no reason for him to pass them up.
Diving below three hundred meters took quite a bit of time, and when Jiang Luoluo was free to fish with him in the evening, he wouldn't be able to dive so deep to hunt.
After all, at such depths, going up and down took so long that there was a risk of being discovered if done too frequently.
