Cave Refuge

As the sunlight poured inside, even though some lights remained on, the room's brightness still increased significantly.

Looking at the living room which had become brighter after opening the window curtains, Mrs. Thompson continued proudly, "I told you the weather outside is fine; just open the curtains instead of wasting electricity by turning on the lights."

Right after Mrs. Thompson finished speaking, Mr. Thompson suddenly remembered that this was Dong Tianyu's first time in the house, and he had decorated the entire place, but he hadn't installed any curtains in Dong Tianyu's room.

Then he glanced towards the kitchen. Although he couldn't directly see the kitchen window, looking at the dark kitchen, Mr. Thompson realized that the kitchen window must also have been covered by curtains installed by Dong Tianyu.

Just as Mrs. Thompson was about to say something else, Mr. Thompson suddenly interrupted, "Son, what happened? Why did you block all the windows with curtains?"

Upon hearing Mr. Thompson speak, Mrs. Thompson then realized, at this time, when clothes return to being "worn for three years, patched for another three, and patched yet again," fabric was a scarce commodity.

Originally, when the two houses were being decorated, neither had curtains, but now that Dong Tianyu had just come back, he had covered all the windows in the rooms with curtains, a move that gave Mrs. Thompson some unpleasant thoughts.

Although Mrs. Thompson didn't ask aloud, Dong Tianyu noticed that his mom was looking at him with concern.

To prevent his mom from worrying further and to answer his dad's recent question, Dong Tianyu didn't say much but simply took out two pairs of sunglasses from the Storage Space.

Mr. and Mrs. Thompson looked puzzled at the two pairs of sunglasses suddenly in their son's hand, and before they could ask, Dong Tianyu directly said, "Mom and Dad, haven't you noticed that the sunlight outside is abnormally bright?"

Upon hearing Dong Tianyu say this, and seeing the sunglasses he produced, Mr. Thompson casually picked up a pair and put them on, then walked directly to the window to look outside, trying to spot the abnormality Dong Tianyu was referring to.

Watching Mr. Thompson's actions, Mrs. Thompson also took a pair of sunglasses from Dong Tianyu, put them on, and stood by the window looking around just like Mr. Thompson.

The two looked outside the window for a long time, noticing that although there were few people on the street, there were still some passersby, but nothing seemed out of the ordinary.

Just as Mr. Thompson was about to turn around and ask Dong Tianyu what exactly was happening, he heard Dong Tianyu's voice behind him, "Look up, are there three suns in the sky?"

Upon hearing this from Dong Tianyu, Mr. and Mrs. Thompson immediately looked up, and then Mrs. Thompson stuttered in shock, "There are, there are four suns in the sky."

After hearing Mrs. Thompson utter those words, Dong Tianyu immediately put on another pair of sunglasses, quickly walked to the window, and looked up at the sky. Before he had hung the curtains, there were clearly only three suns.

But after he had hung the curtains, there appeared one more sun, a discovery that instantly made Dong Tianyu's scalp tingle.

It was only a short amount of time, and yet another sun had appeared in the sky, and Dong Tianyu immediately placed a thermometer on the windowsill again.

Mr. and Mrs. Thompson noticed Dong Tianyu's actions, and although perplexed by his behavior, they didn't say much.

Perhaps because of the three extra suns that suddenly appeared in the sky, Mrs. Thompson no longer said anything about Dong Tianyu drawing the curtains and turning on the lights during the day.

Meanwhile, Mr. Thompson was also pondering some matters, so the atmosphere temporarily became somewhat silent.

After a few minutes, Dong Tianyu picked up the thermometer from the windowsill, noting that it still showed thirty degrees, the same as when he had measured earlier.

Although an extra sun had already appeared in the sky, there was no change in the outdoor temperature, which puzzled Dong Tianyu.

This natural disaster, could it merely be a phenomenon like the polar day seen at the poles? Although a polar night disaster had occurred before, what kind of disaster is a polar day? As long as the outdoor temperature isn't affected by the polar day, Dong Tianyu didn't think it would have any impact on humanity.

From Dong Tianyu's view, the most a polar day could do was disrupt human sleep. If it weren't for the current scarcity of fabric and the fact that most families lacked curtains, Dong Tianyu believed polar days wouldn't affect humans at all.

Far from being detrimental, the occurrence of polar days at this time actually had significant benefits for humanity.

You see, although Blue Star had already successfully invaded another plane for the first time, it still faced invasions from other planes.

As invasions from other planes during the night would severely impact humanity, being in a polar day for a short period actually benefited human counter-invasions significantly.

However, these broader matters were just thoughts for Dong Tianyu; right now, his priority was to take care of his own little family.

"Mom and Dad, while I was hanging the curtains earlier, there were only three suns in the sky. Just now, another sun appeared. Considering this trend, who knows how many more suns will appear later. I suspect polar days might occur; I'll head over to your place later and hang some curtains on your windows too."

Mr. Thompson and Mrs. Thompson naturally understood what polar day weather meant. After seeing the unusual weather outside, Mrs. Thompson, who initially complained about Dong Tianyu drawing the curtains and turning on the lights, didn't say anything further.

Afterward, Dong Tianyu closed the curtains his mother had opened on the balcony, and then the three of them went to the opposite room. Dong Tianyu had just retrieved a set of thick, completely opaque curtains from the Storage Space, identical to those in his room, when...

Mrs. Thompson suddenly spoke, "Son, do you have thinner curtain fabric? Don't use these completely opaque ones; otherwise, we still have to turn on the lights after drawing the curtains."

Upon hearing Mrs. Thompson say this, Dong Tianyu was about to say something but hesitated, worried about upsetting his mother. Considering he still had plenty of fabric stored, he thought whatever type of curtains his mom wanted to hang, he'd use that kind of fabric.

Later, if it turned out to be unsuitable, since he had plenty of fabric, changing curtains would be convenient, and he could switch them out then.

Dong Tianyu hesitated only briefly, soon rationalizing the situation, then didn't put back the thick curtains he had taken out. He was about to go back into the Storage Space to find a thinner curtain fabric when Mr. Thompson noticed Dong Tianyu's earlier hesitance to speak.

Knowing his son had some objections to his wife's suggestion but as a younger member wouldn't say much, he thought now wasn't the time for formalities when safety was essential.

So he directly addressed Dong Tianyu, "Tianyu, just say what you were thinking. Right now, your mom and I might not be considering everything as comprehensively as you."

Hearing Mr. Thompson say this, Mrs. Thompson immediately focused her attention on Dong Tianyu. Seeing this, Dong Tianyu didn't hold back, and openly expressed his thoughts: "Mom and Dad, I suspect it won't be long before there are more than four suns in the sky.

With more and more suns appearing, the sunlight will also become more blinding. I don't know if you understand the issue of light pollution, but I feel that with the increasing number of suns, light pollution might become the norm."

It's true that we can still sleep during the day, but it's only in pitch-dark conditions that we can sleep soundly. That's why I specifically chose these thick non-translucent curtains, to completely block the increasingly blinding outdoor light."

Although like mom suggested, choosing slightly thinner curtains can block some of the blinding light and make the room brighter.

But since electricity is free now, whether the lights are on doesn't matter, so I'd rather turn on the light and have a softer indoor glow than have the room so bright while trying to sleep."
