At the same time, the air was filled with the stench of blood, mixed with smoke, making it truly suffocating.

Lu Wuyai lowered his head and walked quickly forward. He couldn't wait to enter the cave. The outside environment was truly terrible.

Having finally reached the top of the rocky mountain, Lu Wuyai discovered that the surface of the gray pebbles was now covered with numerous black spots, densely packed together. If it weren't for the dim sky, they would definitely have caught the eye.

Lu Wuyai bent down, picked up two stones, and turned to enter the cave.

Inside the cave, the changes in the outside world worried the people inside, and even their voices began to become softer.

When they saw Lu Wuyai return, all the women looked at him.

Lu Wuyai shook his head: "The smell of smoke outside is getting stronger."

After speaking, he took the two stones out of his pocket, touched them lightly on the surface, and a black mark immediately appeared on his fingertip.

“It really does look like ashes.” Lu Wuyai lowered his finger from the tip of his nose and exhaled.

At this moment, Su Xi walked over, patted Lu Wuyai's body, and noticed that there was dust floating on his shirt, which smelled like ashes.

The smell is very peculiar; people really can't figure out where the dust flying in the sky comes from.

“Tell me, did these ashes fall from the clouds?” Lu Wuyai suddenly asked.

Volcanic ash is very fine and lightweight.

"Don't go out." Mauroy's eyes suddenly turned serious.

"If it really is reduced to ashes, then there will probably be a huge disaster. I hope things will get better." Gu Yuxin's tone was very serious; her beautiful face had never been so serious before.

"In the scientific community, there was once a well-known theory about the extinction of dinosaurs."

Gu Yuxin suddenly changed the subject, catching Lu Wuyai and the others off guard.

"Volcanic eruptions send dust and ash into the atmosphere, some of which can remain there for years. If enough volcanic ash and dust accumulate in the atmosphere, sunlight will not reach the Earth, and the lack of sunlight will lead to the extinction of plants. As plants disappear, food animals will die out, followed by carnivores."

"In fact, once the sun can no longer reach the earth, the temperature in the air will be far more intense than hunger."

For a moment, the cave was quiet. Although Gu Yuxin was talking about the possible reasons for the extinction of dinosaurs, the voice-over was talking about the impending disaster beyond the deserted island.

"If that's the case, our black stones will have to be used to grow vegetables. We need to hurry and harvest more mineral materials."

Lu Wuyai frowned and said, "It's not that serious. Maybe the haze in the sky will disappear tomorrow."

Gu Yuxin nodded: "Perhaps I hope my worries are unnecessary."

However, one should always prepare for the worst.

Lu Wuyai recalled that when he opened the blind box before, he also found a box of air purifiers, but at that time, because he was on a deserted island, he never thought he would have the opportunity to use those machines.

"Find some time to go check on that container." Lu Wuyai still remembered the location of the nearby containers and hoped that the machinery there was still there.

Time passed quickly, and by afternoon, the sky outside the cave had completely darkened.

It wasn't dusk yet, but it felt like dusk in the night; I couldn't see my own fingers.

When Lu Wuyai and the others emerged from the cave, the outside world was still thick with smoke. There were no clouds in the sky because there was no light at all. Even though they could see things at night, when they looked up, all they could see was blackness.

Lu Wuyai thought for a moment, then took out a flashlight from his pocket. As soon as the light appeared, some dust floating in the air was completely exposed.

cough cough

After coughing a few times, Lu Wuyai felt very uncomfortable, as did the other women, so he immediately put on a mask.

After that, everyone got on their balance bikes and rushed towards the wolf den.

Before even reaching the wolf's den, Lu Wuyai heard howls. Besides the deep wolf howls, there were also short, sharp roars that sounded like the sounds of other wild beasts.

"Everyone be careful," Lu Wuyai and Song Xiaoyou said almost in unison.

Soon, everyone drew their weapons. As the hoverboards continued forward, leader Lu Wuyai could even smell blood.

In the blink of an eye, Lu Wuyai saw several hyenas lying on the ground, their necks bitten off and carelessly discarded to the side.

Looking up, near the wolf den, a pair of beastly eyes flashed, revealing many cats and mice lurking in the darkness.

Lu Wuyai fired several shots in succession, killing the two cats and dogs beside him.

The others did the same, killing the voyeurs as quickly as possible. They had come here in the dark because they remembered the leopard's earlier actions and realized there might be something serious going on in the wolf's den.

The generals were all raised by Su Xi and the others, so their relationship was naturally very good. Remembering Gu Yuxin's previous warning, I was very worried.

As it turned out, the trip was the right one.

In the forest, besides cats and hyenas, there were actually several tigers. At this moment, they were facing two large black dogs.

Without any hesitation, Lu Wuyai fired his gun, killing several tigers on the spot.

Seeing the power of firearms, the remaining beasts fled instantly without lingering.

Lu Wuyai glanced at the three tigers on the ground and decided to roast the tiger meat directly.

For some reason, these animals all prefer cooked food and seem to be losing interest in raw food, including the nine wolfhound puppies.

Inside the wolf den, the white wolf still lay on the ground. Its broken leg hadn't fully healed. Counting the days, it would take another two months.

Upon seeing Lu Wuyai and the others, Bai Lang couldn't help but let out a soft hiss, looking different from usual and even a little excited.

Gu Yuxin comforted the white wolf and prepared to change its clothes.

Lu Wuyai and several women roasted the three dead tigers alive on the spot. The fire burned fiercely in the forest, with no cover whatsoever.

In the current environment, anyone who dares to come out is courting death. As for the animals, Lu Wuyai touched the gun in his hand, hoping to have more of them to enrich his meat-loving days.

Sure enough, as the fire continued to burn, some ferocious wild animals that were not usually seen in the forest gradually appeared.

At this moment, as time goes by, the dust in the air becomes increasingly dense, and the mask's effectiveness diminishes as one breathes.

An hour later, the fire that had appeared near the wolf's den was finally extinguished, and everything returned to calm.

At this moment, three more tigers, crispy on the outside and tender on the inside, appeared in the wolf den. The generals enjoyed a hearty meal. Their mouths were filled with the delicious aroma, and even Lu Wuyai couldn't help but swallow.

Although Lu Wuyai was greedy, he killed several wild boars while roasting the tiger meat. Their carcasses were placed on his hoverboard; he would deal with them when he returned.

"Lu Wuyai, we have to go. The ashes outside are getting bigger and bigger." Song Xiaoyou's voice came from outside the cave.

Lu Wuyai nodded, reassured Bai Lang and the others, and placed several traps at the cave entrance. Although there were no firearms such as grenades, there were many traps similar to animal traps.

Moreover, Lu Wuyai demonstrated the power of the trap to the general and his men, who were so frightened that they dared not step out of the wolf den.

"Let's go, see you in two days." Su Xi put down a bag of marching rations, and the water pool in the wolf den was filled with fresh water. There was no need to worry about their food in the short term.

Soon, a group of people left the wolf den with five dead wild boars and headed towards the cave.

On the way back, the forest became extremely quiet. Apart from the absence of insects and birds, Lu Wuyai could even clearly hear everyone's heartbeat.

It was still dark. If you looked at the air in front of you, you would see a strange screen of snowflakes. Those were actually ashes.

No one dared to breathe deeply, firstly because the air was filled with dust, and secondly because the atmosphere was depressing.

Upon arriving at the rocky hill, Lu Wuyai first sent men into the cave. He dragged the five wild boars one by one to the edge of the pool and thoroughly cleaned them.

The pool is still crystal clear.

It took another half an hour for Lu Wuyai to clean the wild boar's internal organs on the spot. Then, with dust on his head, he hurriedly returned to the cave.

Standing below the cave entrance, Su Xi had Lu Wuyai grab him, and then used an air gun to blow away the dust off Lu Wuyai's body.

"Cough cough cough."

Lu Wuyai covered his mouth and nose, coughing violently, tears streaming from the corners of his eyes.

But I must say that when I came back, the ash below the cave entrance was as deep as a finger.

"The air quality is terrible." Lu Wuyai sighed, feeling his throat was so dry, as if he had just eaten a bag of limes.

After a while, Lu Wuyai fully recovered and began processing the wild boar meat to prepare dinner for the evening.

In the restaurant outside the booth, a few women found a movie. Although they had already seen it, it was better than nothing.

Lu Wuyai was cutting meat in the kitchen. The wild boar he had killed tonight was a real black-skinned pig. Just looking at the marbling on the meat was a feast for the eyes.

Soon, Lu Wuyai placed the marinated pork on a plate and washed the vegetables he had picked that day so he could wrap them in the roasted pork for later consumption.

Watching movies and eating barbecue, they seemed oblivious to the terrible weather outside.

That evening, after everyone had eaten and drunk their fill, they returned to their respective carriages to rest.

Lu Wuyai lay on the bed, the sound of dust settling in his ears gone. The dust was light; a gust of wind carried it everywhere in the sky.

Soon, Lu Wuyai looked at the animals in the painting and decided to start meditating that night.

But after a while, he felt someone approaching him. He opened his eyes and saw a slender body with an incomparably large figure rushing towards him.

"love me."

Su Xi's words instantly turned Lu Wuyai into a wild beast.

That night, the cat's meows were both embarrassing and intoxicating.

The next day, Lu Wuyai looked at the still dark gray sky outside, and his good mood from the night before was instantly overshadowed.

It's eight in the morning, and the women in the cubicles are still fast asleep. Inside the container, Yuxin, who has been practicing all night, is still lying in bed, her whole body aching.

Lu Wuyai carried two buckets to the pool to replenish the fresh water consumed yesterday.

Walking on the rocky mountain, Lu Wuyai noticed that the ashes were clearer today than yesterday, and the mask could no longer provide any protection.

On the ground, the ashes, like a unique snowflake, gradually covered every corner of the deserted island.

Most importantly, with no light, the temperature in the air is plummeting.

After filling the pool with water, Lu Wuyai carried the buckets back into the cave.

He used an air gun to blow the dust off his body, lifting up the entire entrance to the cave. Lu Wuyai covered his nose, walked to the edge of the pool, and poured the stream water into it.

This freshwater is not drinkable.

Back in the container, he saw Yuxin still sleeping, her exaggerated curves faintly visible under the blanket, which made Lu Wuyai's heart heat up again.

But he still has a lot to do today.

After leaving the cave with a shovel and backpack, Lu Wuyai walked along the mountain path towards the garage.

Driving to a corner of the forest, where there were several shipping containers, Lu Wuyai decided to try his luck and see if he could find a usable air purifier.

When passing by the vegetable garden, Lu Wuyai lingered for a while, walked around the garden, and only left confidently after confirming that the greenhouse was not damaged.

Even without sunlight, Gu Yuxin still laid many black stones in the soil under the greenhouse. With these stones, the vegetables could grow wildly.

Considering the current environment, everyone in the cave agreed that the black stones were of utmost importance and must be stockpiled in large quantities, even if the smog could disappear in a short time.

Half an hour later, Lu Wuyuan's pickup truck stopped in a mountainous area, opposite several shipping containers.

A few months ago, this was an empty lot, but now it is full of green trees. The plants are growing at an unbridled speed, which is simply too fast.

Lu Wuyai glanced at the large tree overhead. The lush foliage could have blocked the ashes, but the ashes were too light and would scatter everywhere with a gust of wind.

He strode inside, opened the container, and a musty smell immediately hit him.

Lu Wuyai noticed that although the container contained a large number of air purifiers, they all appeared to be water-soaked machines. Whether they could be used was a complete mystery.

Finally, Lu Wuyai walked deeper into the box and found two machines in the middle. They looked clean on the water's surface, and hopefully they were still running.

Soon, Lu Wuyai left this place and returned to the original road.

Along the way, you can occasionally see some animals, but they are all corpses lying nearby, looking very pitiful.

Lu Wuyai took a breath. The smell of gunpowder in the air grew stronger, irritating his nasal cavity and causing him to cough incessantly.

Upon arriving at the garage, Lu Wuyai parked the car, closed the door, took the two machines, and immediately entered the hole under the vegetable garden.

He found a generator, plugged in the air purifier, and turned it on. After the machines shook for a while, to Lu Wuyai's astonishment, both machines actually started operating.

Whether it was a psychological suggestion or not, Lu Wuyai felt that the air in the cave seemed to be getting better and better.

Looking at the slowly running air purifier, Lu Wuyai finally smiled.

"Two machines are just too few."

Soon, Lu Wuyai shook his head and told himself that people must be self-sufficient in order to be happy.

At this moment, the other women in the cave also woke up, and when they saw the air purifier next to Lu Wuyai, a hint of surprise appeared in their eyes.

"Where did it come from?" Gu Yuxin asked excitedly.

Lu Wuyai: "I took it from the container outside."

"It's best not to go out during this time. The external environment..." Lu Wuyai shook his head and sighed.

This hazy weather is practically nature's revenge on living things.

It is speculated that with the continued occurrence of smog, the Earth's oxygen levels may drop rapidly, which would be a fatal blow to any living organism.

To ensure sufficient oxygen levels inside the cave, the best solution everyone could think of was through plant photosynthesis.

But now that there's no sunlight, how can we get the plants to produce oxygen?

Finally, Gu Yuxin used some LED beads to make a huge light in the basement to assist the herbs in photosynthesis.

However, lighting 24 hours a day consumes some electricity.

“It won’t take that long.” Mo Luoyi shook her head when she heard Lu Wuyai’s question.

“That skull is also absorbing light energy.” After saying that, Gu Yuxin turned off the light, and the crystal skull began to glow, even brighter than before.

It was a beam of yellow light, seemingly the exact same color as sunlight.

Lu Wuyai nodded. He had indeed forgotten about the crystal skull. It was originally stolen from the Black Cloud Mountain Group, and he hadn't expected it to be so useful.

"This crystal skull is amazing, I can't figure out what it is." Gu Yuxin picked up the crystal skull from the table. Under the light, the skull shone with a bright yellow light, like a sun.

Lu Wuyai and the others were also quite curious. This crystal skull was clearly not as simple as it looked.

"If you turn on the light for 12 hours a day, the crystal bone can release light energy for 12 hours."

Gu Yuxin conducted an experiment and found that the light energy released by the crystal bone is very similar to that of sunlight, which can promote photosynthesis in plants.

And so, the oxygen problem was temporarily solved.

Of course, living conditions aren't that bad now.

On the fifth day of the smog, Lu Wuyai was preparing to set off for Black Cloud Mountain to resume quarrying stones.

This time, Yu Xin, Gu Yu Xin, Su Xi, and Yu Meng Rou were also with them, a total of four women, one person per car, to carry as many black stones as possible.

Inside the cave, the remaining women stayed in their homes, waiting for their return.

In the early morning, the air was still filled with dust, and perhaps it was the impurities in the dust that made the sunlight appear as a crimson, apocalyptic scene.

The five cars sped through the forest. Because of the dense dust, Lu Wuyai once took the wrong car and nearly lost his way.

Moreover, less than two hours after leaving the car, the ventilation vents inside the car became blocked due to environmental factors, and the entire interior space was instantly engulfed in ash.

Everyone had to stop and clean up, wasting more than an hour before they could get back on their feet.

On the subsequent mountain road, visibility decreased, and vehicles drove very slowly. Large amounts of dust settled on the ground, severely hindering the cars' movement.

Along the way, I saw many corpses. It was shocking, and at the same time, I realized how terrible the weather was outside.

Fortunately, everyone on board was wearing a simple mask. While not as effective as a gas mask, it was sufficient to protect against ash and dust in space.
