Li Ruisi's face turned a little red, because he didn't know what he was thinking.

Around noon, Lu Wuyai emerged from the underground cave, drenched in sweat. The underground space was about the size of a basketball court.

After that, cement was laid on the ground, and Lu Wuyai also built a reservoir.

"The swimming pool is for fresh water, so it should be used sparingly," Lu Wuyai reminded him.

After a busy day, Lu Wuyai stood at the cave entrance. Next to him was Li Ruisi, who held a bamboo pole and looked somewhat out of place.

"It's so hot." Lu Wuyai took a breath, feeling that the sun was particularly strong today.

Li Ruisi took a handkerchief out of her pocket, blushed, and handed it to Lu Wuyai.

Lu Wuyai was stunned for a moment, but quickly came to his senses, thanked him, and applied the lint to his face. It smelled really good.

Not long after, Su Xi and the others came over from the hill and brought Li Ruisi a quilt and a bed.

Lu Wuyai went down into the cave, tested the cement, and found that it had already solidified. So he began to pile up all the materials.

“Here’s the bed and blankets. We’ll bring you some food and snacks later.” Su Xi paused, then said, “You should use these things sparingly.”

Li Ruisi looked at the exceptionally warm bed and couldn't help but greet it.

Lu Wuyai said, "From now on, the job of herding cattle will be yours. Remember, no matter what happens at night, don't go out."

The deserted island was unsafe, and there was no time to set traps in this makeshift cave.

Lu Wuyai's reminder made Li Ruisi feel sincerity and kindness, and he kept it all in his heart.

At dusk, Lu Wuyai and You Li brought food to visit Li Ruisi.

At this moment, under the sunlight, the emerald green grassland appears exceptionally beautiful and mysterious.

Li Ruisi sat there in a daze. Before her, the cows had begun to slowly walk towards the fence. As the habit had formed, even without the wolves, the cows had gotten used to returning to the barn to rest at this time.

"Why?" Lu Wuyai shouted at the other person.

Perhaps the sudden sound startled Li Ruisi. When she saw Lu Wuyai, she clutched her chest and slowly calmed herself down.

"What are you thinking?" Lu Wuyai frowned and said, "It's very dangerous for you to be on a deserted island like this."

Li Ruisi pursed her lips, feeling very wronged, and tears began to well up in her long eyelashes.

"What's wrong? You cried after saying just a few words." Lu Wuyai felt that Li Ruisi was too fragile, and letting her graze here might be a mistake.

On the other hand, You Li glared fiercely at Lu Wuyai, then pulled Li Ruisi toward the cave. She didn't know what she had said in between, but she somehow managed to make Li Ruisi laugh again.

After Lu Wuyai and the other two neatly put the things into the cave, they came out of the cave and followed several cows toward the cowshed.

At this point, Lu Wuyai and Song Xiaoyou began to tell Li Ruisi about their specific work in the cowshed, but Li Ruisi said that they had been doing this since they were young.

"You used to be a shepherd," Lu Wuyai asked curiously.

Li Ruisi said with a smile, "My grandfather was a farmer in the United States, and I used to help out there during summer and winter vacations."

This time, both Lu Wuyai and You Li were taken aback.

“Very good.” Lu Wuyai said with a smile. Since Li Ruisi knows what to do, it saves them a lot of trouble and time.

When it got dark, all the cattle were driven into the cowshed.

Before leaving, Lu Wuyai repeatedly instructed Li Ruisi not to leave the cave late at night unless an earthquake occurred.

Li Ruisi nodded, and under the watchful eyes of Lu Wuyai and You Li, he completely closed the cave door.

“Let’s go too,” Lu Wuyai said to Yuri.

Back at Shiqiu, Lu Wuyai caught two crucian carp by the pond to be a dish for tonight.

At seven o'clock, everyone sat around the dining table, eating, chatting, and speculating about what was happening in the outside world.

Last night, Lu Wuyai and his team not only rescued those people, but also received a lot of news from the outside world.

"Now it seems that this deserted island is much safer," Lu Wuyai said, with food still in his mouth.

"The atomic bomb explosions all occurred on the mainland, and the ocean was the least affected."

Some people also raised questions, and Su Xi said at the dinner table, "However, we have met many people one after another. We had all gone to Mount Everest before, but the people on the plane yesterday chose to go to K2."

"Whatever they are, their goal is the mountains, not this deserted island."

Su Xi's words plunged everyone into silence once again.

Finally, Lu Wuyai said, "Ask Li Ruisi tomorrow, maybe we can learn something from him."

Early the next morning, Lu Wuyai came out of the cave and saw herds of cattle grazing on the mountain in the distance, while Li Ruisi was near the fence, harvesting grass with a sickle.

After watching for about half an hour, Lu Wuyai left the hill and came to Li Ruisi's side. He greeted him and handed him the breakfast he was holding.

"Thanks." Li Ruisi smiled and accepted the breakfast. She slept very well last night. To be precise, it was the best sleep she had had in years.

Lu Wuyai smiled, then squatted down and started cutting grass with Li Ruisi to make feed.

Li Ruisi seemed to have actually been to a farm; all her movements were practiced and skillful. She even asked Lu Wuyai if there was any extra fresh water that could be used to wash the cowshed.

She also offered many suggestions regarding the cowshed, all aimed at facilitating the management of the dairy cows. She even mentioned that she knows how to make cheese, and if milk becomes available in the future, she might give it a try.

Around 10 o'clock, Tang Xin and the others also came out of the cave, each carrying a bucket, and began to walk towards the cowshed.

To ensure cleanliness, they clean the cowshed every three days, so the workload is quite large.

At lunchtime, Lu Wuyai and the others simply set up a few tents on the grass outside the cowshed, laid out clean cloths, and sat together, chatting and laughing.

Recalling the issue at dinner last night, Lu Wuyai asked, "Li Ruisi, why did you rush towards those mountains?"

Without even thinking about the question, Li Rui replied directly, "These mountains are practically the base camp for surviving humans."

"You want to know why you didn't choose to go to the desert island, right?"

Lu Wuyai and the others nodded. Shouldn't there be more options on a deserted island?

Li Ruis said, "Although there is less radiation at sea, there is a lack of production lines."

"The base camps stationed on the mountaintops are different. There are many production lines, such as food production lines, clothing production lines, and production lines for daily necessities."

“These are things that a desert island cannot provide.”

Following Li Ruisi's words, everyone became increasingly silent. Although they seemed to have no worries about food and clothing now, in a few years, they wouldn't even have to worry about this matter anymore.

But after a decade or even several decades, the resources in the cave will eventually run out, and even food may become a concern. How will they survive when that time comes?

Seemingly noticing everyone's mood, Li Ruisi didn't say much and just continued eating.

After finishing his meal, Li Ruisi suddenly thought of something, looked up and said, "This deserted island seems to be very, very big."

Lu Wuyai nodded. Even those who had lived there for three years had no idea how big it was.

After lunch, everyone sat on the grass to rest. Time passed by, and many people fell asleep. Li Ruisi, however, seemed full of energy and was still harvesting feed near the cowshed.

As dusk fell, everyone packed up their supplies, said goodbye to Li Ruisi, and returned to the cave to prepare dinner.

......

For several days, the deserted island seemed unusually quiet.

During this autumn month, apart from a few hot days, the rest of the time is cool.

Lu Wuyai and the others had accumulated a large amount of feed, but it was not enough to keep the cattle through the winter.

On the grass, Su Xi and the other women had been working for several hours. Occasionally they would stand up to enjoy the autumn breeze, which made them feel particularly comfortable.

Li Ruisi, standing to the side, pouted, her palms red, looking at Su Xi and the others in disbelief.

"These women have pretty good stamina," Li Ruisi thought incredulously. "It's impossible for an adult to bend over and mow lawns for hours."

On the other side, Lu Wuyai held a gray stone bow, about to shoot a wild rabbit that was wandering nearby preparing for dinner.

Lu Wuyai had forgotten where he got the stone crossbow from. He only knew that it was very heavy. Even he himself couldn't pull the bowstring.

"But even so, the power of an arrow is not much greater than that of a bullet." Lu Wuyai took a breath, pulled back the bowstring with all his might, and a gray arrow was immediately shot out.

The gray arrow was so fast after it left the bowstring that even Lu Wuyai couldn't react in time.

In a second, or rather, less than a breath, the gray arrow struck its target. It was a yellow-haired wild rabbit.

"At close range, its power is comparable to a bullet." Lu Wuyai looked thoughtfully at the rabbit that had been hit by the arrow.

Within fifty meters, an arrow can easily catch a bullet.

However, archery is not easy, especially hitting the target, which is even more difficult.

Although both archery and shooting are shooting, they are different in difficulty.

After a long period of training, Lu Wuyai was finally able to attack moving targets.

Walking over, Lu Wuyai pulled out the arrow, checked it first, then threw the dead rabbit into the bamboo basket behind him, and finally continued to practice his archery skills on the grassland.

Unbeknownst to him, Lu Wuyai was already several kilometers away from the cowshed and had crossed several mountains.

During this season, the grassland is mostly inhabited by cattle, sheep, and horses, but amidst the seemingly peaceful weeds, one can often spot some unusual figures, such as cheetahs.

Although there are no dense forests, the weeds grow enough to conceal these fierce predators.

Lu Wuyai thought for a while, but instead of disrupting the natural food chain, he took a step to the side and continued to look for a suitable hunting target.

“I don’t know what this crossbow is made of,” Lu Wuyai couldn’t help but complain again.

In the afternoon, Lu Wuyai came down from the mountain. The bamboo basket on his back was already full of rabbits, and a faint fishy smell wafted around him.

However, the sharp-eyed Song Xiaoyou noticed that Lu Wuyai was holding a basket that seemed to contain some kind of surprise.

"For you." Lu Wuyai smiled and handed the basket in his hand to Song Xiaoyou and Su Xi.

When I opened the basket, I found three little squirrels. They had red fur and white ear tips. They looked very cute.

Su Xi asked happily, "Where did you get this?"

Lu Wuyai pointed in the direction of the dead wood forest and said, "I was chasing a wild rabbit just now, and I fell off a tree."

"What will it eat? Otherwise, put it back." Su Xi was a little reluctant to let go, but considering the heavy responsibility of raising three little lives, she decided to release it back into nature.

Lu Wuyai quickly waved his hand: "I was very careful just now. There are no other large pine trees nearby. If I put it back now, it might be eaten by other poisonous snakes and birds."

Hearing this, Su Xi and Song Xiaoyou decided to let them stay. As for food, they set their sights on the herds of cattle.

“I heard from Li Ruisi that it’s about time to milk the cows,” Su Xi said.

That very evening, Lu Wuyai and the others carried plastic buckets and followed Li Ruisi to learn the milking process.

Although it looks simple, it's actually quite chaotic in practice and requires a lot of skill. One wrong move and you'll get a severe setback, which is why several women haven't dared to try it.

The simplest example is Li Ruisi, who squeezed out a large amount of milk in just a few minutes.

The warm sunlight shone on the girl's face, while the black and white striped cow grazed, completely unaware that it had become the center of attention.

The sound of a cow mooing~~~.

The occasional mooing of the cows sounded particularly soft.

Before dusk enveloped the deserted island, the flies and insects on the grass became increasingly rampant. Lu Wuyai and the others lit a special kind of fodder; its pungent odor spread with the wind across the grassland, repelling the insects.

Soon after, Li Ruisi went into the cave to rest, while the others returned to the hill and began preparing dinner.

"How about we let the little girl come to Shiqiu for dinner sometime?" Su Xi said.

Lu Wuyai fell silent, then finally shook his head. He didn't accept Su Xi's suggestion. The reason was that he wasn't familiar with it.

They had no real contact with the little girl who had suddenly appeared before them; the cave was full of things. If she harbored ill intentions, a single spark could destroy everything in the burial mound.

“Let’s go out and have fun together another day,” Kim Seok-rok suggested.

In this season, the autumn air is crisp and the sun shines brightly. It's unlikely we'll encounter such a time again.

“Then let’s continue our island tour.” Lu Wuyai thought of the forest where saber-toothed tigers roamed. It was pristine and dense, unaffected by the hazy atmosphere of the past few days.

Recalling those hazy days, Lu Wuyai remembered some things he had asked Li Ruisi before. Indeed, those hazy days only happened in one hemisphere.

"Circling the island is too tiring, and I always feel unsafe at sea."

The suggestion to circle the island was quickly rejected by the women, mainly due to safety concerns.

"Let's just wander around then, this deserted island is too big anyway."

And so, in this autumn, an unexpected trip began.

It was late at night, and the car stopped near the cowshed. Su Xi woke the sleeping little girl and opened the cowshed door. For the next few days, the wolves and cows were allowed to roam freely on the grassland.

Once in the car, Li Ruisi was still half asleep when he asked Su Xi why she didn't drive during the day.

“It’s the same.” Su Xi smiled.

Li Ruisi then noticed that in the darkness, the eyes of the people around him seemed to be filled with a layer of fluorescence, which made him a little nervous.

But the trembling sensation quickly hypnotized her again when the car started.

It wasn't until he woke up the next day that Li Ruisi realized that he and these people he had just met were indeed heading south, but he didn't know where they were going.

Li Ruisi, who had just experienced a plane crash, went through a period of ups and downs.

“Eat something after you get up,” Lu Wuyai said. He saw in the rearview mirror that Li Ruisi had woken up, but everyone else in the car was still asleep.

Lu Wuyai slept in the car last night, and this morning he was the driver of the car.

We set off this time, with three solar-powered electric vehicles and ten people in total. Along the way, we saw not only lush green grasslands but also mountains that gradually deepened in the distance.

On the tenth day after leaving Shiqiu, Lu Wuyai and his companions finally had to stop their vehicle. A massive mountain peak appeared before them, like a natural abyss blocking their path. At the summit stood a towering snow-capped mountain, its fierce power palpable. A fierce wind howled.

“This should be the black mountain we saw at sea,” Lu Wuyai said.

During their fourteen-day voyage at sea, they saw the side of a mountain. Although they did not catch a glimpse of the entire mountain, they believed it to be the same mountain.

Behind the snow-capped peak, a saber-toothed tiger appeared.

Three cars were parked on the gravel slope at the foot of the mountain, and Lu Wuyai covered them with gray car covers.

Of the three vehicles that arrived, one was filled with fresh water and marching rations, enough to sustain ten people for a month if needed.

Now, only ten days have passed, and they still have to walk the rest of the road on their own.

Feeling the magnificence and grandeur of the mountains opposite, everyone couldn't help but feel a sense of pressure.

“Let’s go around and take a look.” Lu Wuyai pointed to one side at the foot of the mountain and found that the location was relatively flat and easily visible, so it was less dangerous.

Soon, Lu Wuyai, carrying two backpacks and a jacket, led the group ahead.

Half an hour later, they stopped at the foot of the mountain, looking strange.

At the end of the path, there is a cliff with a huge drop. Looking ahead along it, the terrain is the same, as if someone had cut open the deserted island with a knife, and part of the terrain moved upwards, eventually forming this cliff.

Even more eerie is that on one side of the cliff lies a vast grassland, while below, an endless ancient forest stretches out. Sunlight shines through the treetops, making them appear exceptionally deep.

“Getting through this hurdle is too difficult,” Lu Wuyai said. “There’s another problem.”

Even if you manage to get to the top, you will still face difficulties when you come back up.

"Visually, it looks like it's over 100 meters away, which is about 30 stories high," said Song Xiaoyou.

Lu Wuyai shrugged: "Going down is no problem, but coming up is more troublesome."

The cliff face was completely bare. While ropes were helpful for descending, climbing back up was much more difficult, especially since most women have limited arm strength and cannot climb using ropes.

"There are no big trees on this grassland, and we can't build a raft to cross the sea."

“Then wait for the tide to go out,” Su Xi said.

It was a great idea, but when the tide went out at dusk, they found that even at low tide, it was difficult to walk in this area because there were too many reefs.
