Actually, when it's tough to reel in the fish, you can also use this stance to yank it out, as long as you're stronger than the fish.
Right now, the fish isn't putting up much of a fight, so tucking the rod under the armpit is quite suitable for one-handed reeling, and also convenient for the other hand to quickly reel in the line.
As he gradually reeled in the line, he felt the fish's strength dwindling, its resistance getting weaker and weaker.
Now, he was ready to play his big move.
Grabbing the fishing rod with both hands again, he jolted it upwards from a position parallel to the water, and the fish in the water was suddenly pulled in much closer, allowing him to retrieve several loops of the line in one go.
But the rod's tip shouldn't be pressed too low. Fishing big fish like this, without a lot of time, it's very difficult to completely drain their stamina, as they can strike back at any moment.
Therefore, if the rod is pressed too low, it's tough to lift it again.
