Sui Chengguo was caught between a rock and a hard place, to leave, he had to pull up the stone, but from the feeling in his hands, that thing underwater was definitely not a fish.
Just as Sui Chengguo hesitated for a moment, the rope in the water started to move on its own, stretching taut and constantly shaking. Sui Chengguo's heart skipped a beat, and he immediately realized that the thing underwater was climbing up the rope!
Although he didn't know what was underwater, allowing it to climb up would mean even ten lives wouldn't be enough for him. Sui Chengguo made a split-second decision, he released the rope from his grasp, letting the half-pulled stone sink back to the riverbed, and immediately began rummaging on the boat, hoping to find a dagger or a similar sharp weapon to cut the rope tied to the mooring post.
At that moment, the priority was no longer the mission; it was survival, and based on Sui Chengguo's experience, he was convinced the mission had already failed.
