With the midday temperature so high now, the fish conditions can be foreseen to definitely be affected. That's why Zhang Yang didn't rush to create a fishing spot to attract fish after starting to fish, but rather gathered some intelligence to make an initial judgment and then adjusted reactively.
The strategy of planning before taking action as described in military tactics is exactly the current situation.
The next few minutes indeed confirmed Zhang Yang's judgment.
He cast five successive lines, each time using regular baiting and casting into the water, letting the fishing tackle complete the full travel process, and waiting several seconds after the double hooks reached the bottom to confirm no movement, before pulling the rod back up to switch bait and cast another line.
The test fishing situation was even worse than Zhang Yang's initial prediction. In five or six test casts, not even a proper bobber movement was observed.
