791 The Ferocious Monster Worm (1/2)

Although the appearance of ordinary Clam Worms was not much to be complimented, they were actually the equivalent of Mealworms in the water. They were harmless, could be used as food for several different kinds of fish, and their protein content was not low. There were even people in the southern seas that cooked them as a dish for consumption. But, some Clam Worms were slightly poisonous, and some people developed an allergic reaction after they came into direct contact with it.

However, ordinary Clam Worms were not aggressive, so it was not possible for them to cause the disappearance of the fish.

Zhang Zian's heart skipped a beat as he continued to listen. He hurriedly said, ”Let me take another look at that picture.”

Everyone else who was present originally guessed the reason for the disappearance of the fish when they suddenly saw the change on Zian's face. He became very serious. They stopped talking and looked at one another; even Welder Zhao, who kept boasting about how he had saved money, was also somewhat uneasy.

Electrician Wu showed Zhang Zian the picture again. His phone was of an older model so the picture he took was not very clear.

”What is it, Store Manager Zhang? Is this a Clam Worm?” Electrician Wu asked. He was worried about his fellow colleague.

Zhang Zian looked at the picture countless times. ”It's indeed a Clam Worm, there's no mistake about it. But…”

”But what?”

”Is this the only picture?” Zhang Zian asked. ”I'm worried that, aside from the Clam Worms, there might be something else hiding in this reef rock.”

Electrician Wu started to get nervous after listening to what Zhang Zian said. He suddenly remembered. ”Right, I've also recorded a video for my wife, hoping for her to agree on letting me change to a bigger fish tank. This video is about the fish tank in general and not the Clam Worms… Is that okay?”

”Yes, better than nothing,” Zhang Zian said.

”Let me look for it.”

Electrician Wu swiped his fingers across his phone a few times before he found the previously recorded video clip and pressed play.

The quality of the recording wasn't that good. Aside from its clarity, the video was also shaking so badly that Zhang Zian wanted to persuade Electrician Wu to conduct an early screening of the Parkinson's disease…

Welder Zhao's homemade fish tank was very huge. It's length was one and a half meters long and, although it's width was not carefully measured, it was certainly not narrow. There were several black reef rocks piled in the center of the fish tank and, at the bottom of the fish tank, was a layer of rough sand. A few common, small fish were swimming between the overgrown seaweeds, feeding on the algae from time to time.

Overall, the fish tank was quite well set up, but because of the pursuit of the extreme limits of cost-saving, it was not equipped with a skimmer. There were excessive nutrients in the water and the water was slightly turbid. Fortunately, there were only a few fish, and the water quality would not deteriorate that quickly.

The reef rock was chipped from the beach. Its interior were filled with large and small holes––small holes that only a grain of rice could be stuffed into. The larger holes, on the other hand, ran through the inside of the rock, bending and turning. There was no way to know how long it ran.

The more space in the reef rock, the better it was. It could reduce the weight of the reef rock and it could also provide a breeding ground for the proliferation of the nitrifying bacterias. Welder Zhao must have considered this, too, when he mined for the reef rocks.

”Stop! What's that thing?”

Zhang Zian suddenly found something in the corner of the video image. There was something moving in the reef rocks. It was very fast, but the movement was very small, like something sticking its head out to observe the outside world. It then quickly contracted, only leaving a whirl of sand that was stirred by the movement.

Zian was able to notice that because he knew that the problem was definitely from the reef rock, so he kept his eyes on them.

”What?”

Electrician Wu's eyes were affected by his old age and he didn't have any glasses on, so he wasn't able to catch what Zian noticed.
