The sound of the iron leaves rustled like waves crashing against our bamboo raft. Although the raft was tied tightly, it couldn't withstand the onslaught of the ravenous knife-toothed piranhas that were trying to gnaw at it.
In a moment of panic, we had no choice but to swing our entrenching shovels to chop at the fish swimming nearby. As I plunged my shovel into the water, a couple of those piranhas clamped down on it like wild dogs. I quickly yanked my hand back, shaking off the fish, but when I looked down, cold sweat broke out. The sharp edge of the shovel was marked with several rows of jagged bite marks.
That was just a few fish that had come close; more were surging in from behind. If we didn't take action soon, our bamboo raft would be torn to shreds in mere seconds.
