After returning to the small farm with the newly acquired fish larvae, Kim Haru immediately placed them into the water tank that he had prepared in advance.
The water tank had been specially made in the past couple of days, with glass panels on all sides.
There was no perfect way to seal the gaps for now, so he had to use Unmelted Frost Bamboo Tree to freeze the seams, barely holding the glass panels in place and preventing the water from spilling out.
The only drawback was that this water tank couldn't be placed inside the wooden cabin because the indoor heating would melt the ice sealing the gaps.
At first, Kim Haru had planned to place the water tank in the living room of the wooden cabin, pretending it was a decorative aquarium, making it convenient for him to observe the growth of the fish.
After all, in the dead of winter, the pond was frozen, and he feared that the survival rate of the tiny fish larvae would be very low if he just dumped them into the pond.
However, it wasn't a big issue that the water tank couldn't be placed inside the wooden cabin.
After all, the fish had been born in the cold environment of the ice and snow.
Kim Haru thought they probably wouldn't be afraid of the cold weather, especially since the Unmelted Frost Bamboo Tree could control the temperature, ensuring the water stayed above freezing.
"Just keep an eye on your cat," Go Okrim said, helping to place stones and sand into the water tank to simulate a more natural environment. "Don't let Luna eat all the fish inside."
Lina is very well-behaved," Kang Hose replied. "It won't steal the fish. Don't worry, Brother Go."
While the two were talking, Kim Haru had already placed the final stone.
The sand and mud that had been scattered earlier had settled at the bottom of the tank, and the water had become clear.
Kim Haru had originally thought about adding some aquatic plants, but with it being winter, he couldn't find any.
Not only had he not found real aquatic plants, but he also couldn't find any artificial green plants, so he decided not to add anything to the tank.
As a result, the water tank now contained only gray stones, brown sand, and soon-to-be-added black fish larvae.
Everything was in dark tones.
Kim Haru poured all the fish larvae into the tank.
After thinking for a moment, he worried that these fish larvae might end up in the same situation as the black pigs and ducks in the animal research institute.

So, he decided to purchase 10 additional small fish larvae from the system's trade interface.
These larvae were unlocked when Kim Haru acquired the batch of fish larvae.
The name was simple and easy to understand—they were called spiky fish.
Kim Haru thought that with the system's fish larvae present, they should be able to guide the wild fish larvae somewhat.
As soon as the larvae entered the water, they started swimming joyfully.
Those that had been crowded together quickly scattered, and in an instant, the whole tank was filled with them.
It looked like a drop of ink had been diluted and spread throughout the entire tank.
"Looks like these guys don't like to stick together, huh?" Go Okrim raised an eyebrow as he observed the situation.
Kim Haru also felt that this wasn't ideal for their fish pond farming: "When feeding them, make sure to watch if any of the larvae start fighting each other. If they do, we'll need to separate them."
Of course, Kim Haru hoped that there would be no such issue.
Go Okrim and Kang Hose both nodded in agreement.
The fish larvae couldn't stay in the water tank forever.
Right now, the pond was covered in ice, and the holes they had made for fishing were gradually freezing over as well.
Kim Haru had considered placing the fish larvae in the pond, but that would have to wait until he had broken up all the ice on the pond.
Moreover, he couldn't just release them into the pond to swim freely.
From the species of creatures Kim Haru had already fished out of the pond, it was clear that creatures like the Deepsea Light Fish, the Green Jade Shrimp and even the Giant Spider Crab that had appeared only once, would likely eat these small fish larvae.
At the very least, he would need to make a net to create a dedicated area for the spiky fish.
With the current size of the spiky fish, Kim Haru wasn't sure what kind of net would be able to contain them.
He'd need to wait for the fish larvae to grow a little larger, at least until they were too big to escape through a fishing net, before releasing them into the pond.
Most importantly, Kim Haru still hadn't found anything suitable for making a fishing net.
"Mr. Kim, I've only found these ropes," Kang Hose said, presenting a small bundle of ropes.
He had searched through everything in the small farm that could possibly be used, but there was only a tiny amount.
Go Okrim had gone to the Pyeongseong Safe Zone trading market to look around, but even he returned empty-handed.
"The materials needed for making ropes are becoming increasingly scarce. Most people don't have any spare ropes. It seems like something insignificant at first, but it turns out to be indispensable. The trading market doesn't even sell ropes," Go Okrim shook his head.
The logistics department of the Pyeongseong Safe Zone also didn't have fishing nets.
After the river creatures mutated, the fishing nets from before the apocalypse were no longer useful.
Some of them were damaged during the fight with mutated creatures, while others were repurposed as ropes when there was a shortage.
As a result, very few remained.
Unable to find a complete fishing net, Kim Haru decided to make ropes himself.
However, considering the current situation, they couldn't even find much rope.
