After having breakfast, Lin Chu changed into a diving suit she had retrieved from the space at Ma Yan.

After confirming through the cat’s-eye view that there was no problem outside the door, Lin Chu put on her diving mask, opened the yard gate, and dove headfirst into the murky water.

The dirty water enveloped her, but fortunately, Lin Chu had an oxygen mask, so she didn’t have to endure the foul smell.

The reason she went out this time was twofold: on the one hand, to scout the nearby terrain, and on the other, to visit other houses to scavenge for supplies.

This house, with its attic and terrace, was just one of many in the area. Nearly every rooftop of the residential buildings here had a similar layout.

She believed that bird nets were certainly not unique to just one house.

Catching fish was a required task to accumulate points in this mission world. Dead fish required 10 to earn 1 point, while live fish could earn 1 point for just 2.

In comparison, catching live fish was much more efficient.

Therefore, she needed to find more bird nets to repurpose them into fishing nets.

Lin Chu had already thoroughly searched the shelter house from top to bottom. She swam out of the window and swam into the neighboring house.

Unfortunately, the owner of this house didn’t seem to be a gardening enthusiast, and Lin Chu didn’t find any gardening tools here.

However, she did find three 10L water buckets and a large bathtub meant for children.

Without hesitation, she stored the buckets and the tub into her space.

Her plan to store hot water last night required enough water containers to support it.

Any water container over 10L from the houses she visited would not be left behind.

The oxygen mask could only be used for one hour at a time.

Lin Chu could only return to the shelter every hour to rest, wait for the mask to cool for half an hour, and then set out again.

She couldn’t help but wish greedily that if she could have two such convenient oxygen masks, that would be great.

That day, Lin Chu searched about 10 houses, covering the rooftops of five nearby buildings.

She collected four bird nets, several large water buckets, three bathtubs (one of which was an adult-sized tub, significantly larger than the child-sized ones), five bags of rice that had been vacuum-sealed but had already been exposed to water, and various other waterlogged food items.

Lin Chu stored everything into her space.

For others, these foods would be inedible, but Lin Chu had the skill to turn waste into treasure.

Three times a day, she needed enough waste materials to improve her skill at turning waste into treasure, and these contaminated foods were perfect for that.

The rooftops she searched today were the ones on the top floors of the residential buildings, which were likely the last to be flooded and also the least submerged.

Many things had already been looted, leaving behind little food.

Lin Chu planned to collect enough bird nets first, then raid the buildings one by one.

After all, bird nets were crucial for accumulating points.

She believed that other mission participants would also realize that bird nets could be used as fishing nets.

If that were the case, she would take advantage of her geographical advantage and gather all these useful tools before anyone else.

She estimated that in this area, there were about 20 pointed-roof buildings with exposed tops.

The standard layout was one elevator serving two households, so there were 40 rooftops she needed to search.

At a rate of 10 houses a day, she would finish searching the rooftops in 4 days.

However, when she finished her search and returned to the shelter that evening, she raised her head in confusion and looked at the ceiling.

If she remembered correctly, when the house had first been flooded yesterday, it was completely submerged.

Now, however, the water level was about 30 cm below the ceiling.

Could it be that the water level was actually starting to drop?

Lin Chu looked out the window.

Only black fish swam by, creating faint ripples in the water.

There was no sign of rain.

The flooded world wasn’t even raining.

This was unscientific.

Lin Chu furrowed her brows and observed the water level once more. To avoid making a mistake, she took out a pen from her space and marked 1 cm above the current water level.

Then, she returned to the shelter.

Covered in muddy filth, Lin Chu removed her diving suit and immediately went into the bathroom.

The diving suit she had taken off was cleaned and hung to dry by Xiao Er in the yard.

Any dirty water that dripped in was also cleaned up by Xiao Er, as it had been instructed to help.

Lin Chu could now clearly see that Xiao Er completed her tasks 100% according to her orders.

With such a diligent and obedient robot, it felt like having a thoughtful nanny, making life much more comfortable.

The next day, Lin Chu once again put on her diving suit and mask and went out.

As soon as she stepped outside, she noticed that the water level had already dropped from where it had been the previous day.

Compared to her mark from yesterday, it had dropped another 50 cm.

If it dropped any further, the door of her shelter would be exposed above the water.

But this was something Lin Chu couldn’t change, so she decided not to think too much about it and continued swimming toward her predetermined destination.

She was still searching the rooftops of the houses with terraces, prepared for the possibility of finding little food.

But when she reached the last house on her list for the day, she found a package wrapped in several layers of sealing bags.

Lin Chu stored the package in her space, and after returning to the shelter, she opened it. Inside, she found compressed biscuits vacuum-sealed in foil without any labels or printed markings.

There were also several cans.

Lin Chu roughly counted.

There were about 100 compressed biscuits and around 50 cans.

Such supplies might not have seemed significant before the apocalypse.

But now, in the apocalypse, these compressed biscuits and cans were invaluable.

The previous owner of these supplies wouldn’t have left them behind during their retreat.

Even if they hadn’t had time to take them at first, they would have come back for them later.

But this package of supplies had been waterproofed, and it was clearly hidden here intentionally.

Lin Chu recalled the apocalyptic novels she had read, where some responsible authorities would conduct airdrops of food to survivors by neighborhood units during the apocalypse.

The most common items in those airdrops were bread, compressed biscuits, and cans.

This package she had found had no trademark or flashy prints, just the plain silver-gray foil packaging.

It was highly likely that this was a temporary food airdrop made by the authorities for survivors after the apocalypse.

One person couldn’t have distributed such large quantities of supplies.

It was very likely that these supplies had been embezzled by the officials in charge of distributing food.

Thinking this, Lin Chu carefully repackaged the supplies and returned them to the building where she had found them.

It was obvious that these things weren’t just hidden once.

The person who hid them had been like a hamster, secretly stashing the food little by little in buildings flooded by the water.

Lin Chu wanted to find out who this person was.

But before doing that, she didn’t intend to alert anyone. For now, she would leave the supplies where they were.
