By noon, half of the ship's lower deck was piled with fish carcasses, black smoke was billowing from the incinerator chimney, and the temperature was so high that it could burn your hands.

In the afternoon, Zhou Shuwan and his friends prepared to set off.

The task that Captain Shang gave Zhou Shuwan was to go out and find a sea area that was more suitable for living, that is, a sea area that was not so severely polluted by corpses.

At this time, the sea level is relatively calm because the ice has melted. If there is no strong wind, the sea is relatively calm and the reconnaissance ship can travel alone.

Moreover, because the sea level has risen by more than ten meters, it is no longer meaningful for everyone to stay on the island.

Naturally, Zhou Shuwan was the one responsible for this reconnaissance mission.

Zhou Shuwan can detect a wider range in the sea water, so it is very appropriate to let her find a place more suitable for the mothership to dock.

So, that afternoon, Zhou Shuwan took his parents and Qi Mingyu and set off on the reconnaissance ship.

The reconnaissance ship slowly sailed away from the mother ship.

Zhou Shuwan stood at the bow, looking towards the direction of the small island.

The outline of land is no longer visible on the sea surface there. Only the occasional bubbles rising from fifteen or sixteen meters below the surface prove that this sea area was once a small island exposed to the sea where people could stand.

They seem to be constantly searching for new habitats, and for various reasons, they keep moving.

There is no time to stop completely and safely.

The sea breeze was howling, white waves were hitting the side of the ship, and the reconnaissance ship was making a low rumbling sound.

Zhou Shuwan tightly grasped the handrail on the deck, feeling the swaying of the ship and looking at the sea in the distance.

There were still a large number of dead fish floating there, emitting a disgusting stench that could be smelled even through the cabin.

Zhou Shuwan took a deep breath and tried not to pay attention to the nauseating smell.

She began to use space to detect the distribution of nearby fish carcasses in order to find cleaner waters.

She was completely absorbed, as if she were in a vast ocean world, with all kinds of fish carcasses and pollutants clearly presented in her perception.

As she sailed, she gradually discovered some patterns.

The seabed is a gentle slope of sand and gravel with no depressions, so the fish carcasses are carried away by the ocean currents.

There will be very few dead fish in these waters.

However, Zhou Shuwan has not yet found a satisfactory place.

She commanded the reconnaissance ship to continue heading southeast.

"Two kilometers southeast, my detector shows that the density of fish carcasses continues to decrease. Let's explore further. Maybe we can find a cleaner area!"

The captain nodded, turned the steering wheel, and the propeller stirred up the calm sea and headed in a new direction.

After four hours of uninterrupted monitoring, Zhou Shuwan fell into a drowsy sleep.

Qi Mingyu suddenly looked up into the distance and discovered something strange.

"Look, the sea surface over there seems a little different. The ripples are denser than before."

His observations were astonishingly sharp.

Everyone looked in the direction he pointed.

The originally azure sea water suddenly became turbid a few hundred meters ahead, as if there was a layer of gray fog covering the water.

As the boat got closer, a strong stench drifted in on the sea breeze, more pungent than the smell of the original island waters, as if countless dead fish had been rotting in a confined space for half a month.

The captain immediately covered his mouth and nose, frowned and said, "Something's wrong, slow down quickly!"

Zhou Shuwan was awakened by the sound. Before she was fully awake, the stench around her was so strong that she was about to cry.

At the same time, she had sensed that something was wrong in this sea area.

The sea ahead was covered with dense reefs underwater, and the cracks and depressions in the reefs were filled with rotting fish carcasses.

Sardines as small as a palm and tuna as large as half a meter long were piled up among the reefs. Some of the fish carcasses were swollen and deformed, their abdomens ruptured, and their dark green internal organs mixed with black water flowed down the reefs.

Some are left with only a skeleton, with sticky rotten flesh hanging on the bones, and are crumbling from being gnawed by microorganisms in the sea water.

These fish carcasses almost covered the entire reef area with a layer of decay, and the density was far greater than any area previously explored.

"It's a reef area!" Zhou Shuwan said in a heavy tone, "The fish carcasses are all stuck in the cracks of the reef. The water can't flush them out, so they're all rotting here. The pollution is even worse than where we are!"

On the water, the captain was checking the air quality with an air quality meter. The hydrogen sulfide concentration on the screen suddenly soared. He shouted, "Quickly, sail away! The air here is poisonous. Staying here for too long will cause poisoning!"

The driver immediately turned the boat around, and the long and narrow hull slowly exited the reef area, and the stench gradually faded.

Only after they left the foul reef area did the sea gradually return to its previous clarity.

Zhou Shuwan leaned on the side of the boat, looking at the calm sea, and became more clear in his mind about where they should choose to live.

In a sea area that can retain life, there must be no dead corners that "hide filth and dirt". It must be a place where water can flow freely and fish carcasses can be carried away.

Any place with reefs or depressions is not feasible.

For the next two days, they sailed slowly following the ocean current.

The sea is not always calm.

Sometimes they encountered areas where the seabed sloped too steeply and the current was so strong that it was difficult to stand steadily;

Sometimes, although the sea surface is calm, there are shallows and depressions underwater, with fish carcasses piled up above and below the water.

On the third day, they finally found the sea area that met their requirements.

Before arriving here, Zhou Shuwan felt something was different.

In her perception, she could clearly "see" that the sea water here was clearer than any place they had passed before, and the sunlight could shine through the water surface to a depth of ten meters. The water flow touched by her fingertips was steady but powerful, with a fresh breath.

Further exploration revealed that the seabed was a flat sandy and gravel area with no reefs or depressions.

Although there are no living fish, fortunately the water is clean enough.

After three days and three nights, I finally got something.

Zhou Shuwan suppressed his excitement and immediately directed the reconnaissance ship in that direction.

Gradually, everyone noticed something unusual on the sea.

Just by looking with the naked eye, you can clearly feel that the sea here is cleaner than other places.

Everyone was very excited.

When they arrived at this sea area, the captain asked people to pour the seawater sample into the test tube. After the reagent reacted, the liquid turned light blue.

This is the color that indicates water quality meets standards.

He stared at the numbers on the screen and nodded. "The pollution index is 8 points lower than the original sea area! The dissolved oxygen content is 7 mg/L, and the water flow rate is stable at 0.25 m/s. It meets the requirements perfectly!"

Zhou Shuwan climbed onto the deck and looked at the sea in front of him.

The sunlight shines on the sea, creating golden waves. The sea in the distance is connected to the skyline, and the water is a slightly dark blue.

Although it is not as clear and clean as before the eternal night, it is already very rare.
