Upon reaching this point, Lu Wuyai recalled the changes he had witnessed in the forest, wondering if the oxygen content had suddenly increased again.
“Even if it increases, it shouldn’t be this fast,” Gu Yuxin told Lu Wuyai not to be suspicious. An increase in oxygen levels wouldn’t happen overnight. It was probably because everyone had slept in the cave overnight. Although it wasn’t a completely enclosed space, the air was somewhat different from the outside.
"Now, there is no harm."
"However, we must also be vigilant. With the increase in oxygen levels, besides changes in ourselves, the most troublesome thing is nature."
When Lu Wuyai mentioned this to others, he noticed that Gu Yuxin's expression became very serious and worried. However, the next person to speak was indeed Song Xiaoyou.
"More than 300 million years ago, the Earth was in the late Carboniferous period. At that time, the Earth's oxygen content was as high as 40%, making it a truly high-oxygen environment."
"Most of the plants back then were towering trees, truly massive trees. Their needles covered the earth. During photosynthesis, they absorbed carbon dioxide and released oxygen, resulting in the same amount of oxygen in the air as today. Double that."
"During the Late Carboniferous, terrestrial animals were mainly large insects and amphibians."
Upon hearing this, the others immediately understood that Song Xiaoyou and Gu Yuxin were worried about insects and amphibians.
If oxygen levels continue to increase, the next stage of animal evolution may bring them enormous trouble.
Although biological evolution may not undergo dramatic changes in the short term, and oxygen levels may not necessarily rise again, we should always prepare for the worst.
“In fact, it’s not just insects and amphibians that undergo changes; some mammals do too. I suspect that the wild boar we saw earlier might have been the beginning of a mutation,” Gu Yuxin said.
“Not necessarily.” Lu Wuyai shook his head. He had seen large snakes before, so he thought the large animals on those deserted islands were normal.
Moreover, this wild boar may have grown larger because it ate the black stone.
"Most importantly, you must be careful about fire. Song Xiaoyou reminded that the oxygen content in the air is already 30%, and fires are very likely to occur in the upcoming summer."
Once a large-scale wildfire breaks out, it is not easy to extinguish.
Later, in order to adapt to the environment as quickly as possible, everyone opened the doors of the caves and burrows to allow air to circulate.
Perhaps thanks to Gu Yuxin's reminder, many people have already discovered that in an environment with an oxygen content of 30%, the brain's thinking does indeed change rapidly and its energy is abundant.
"This feeling is really good," Lu Wuyai thought to himself. In addition, he also found that he could easily enter a state of concentration, no matter when or where.
Moreover, after entering meditation, Lu Wuyai also noticed a distinct warm current flowing through his entire body. Although he had experienced it before, it was never as pronounced as it was now.
"Under these circumstances, can other women also enter into meditation?" Lu Wuyai got up and went to the living room to relieve his boredom, pulling Su Xi aside to let her appreciate the ancient paintings.
"Haven't you tried this before?" Su Xi asked, looking displeased. She felt that staring blankly at these ancient paintings was a very foolish thing to do.
"I let you try, but I didn't let you eat rice," Lu Wuyai said. In the past, the women who reacted to ancient paintings were all women who had had intimate relationships with him. Now he's letting Su Xi try, hoping that the changing environment will make a difference.
Su Xi snorted, but due to Lu Wuyai's strength, she still tried. As a result, she opened her eyes, her face showing excitement.
"It's really okay."
"Really?" Lu Wuyai's eyes widened. After realizing that Su Xi hadn't lied to him, he believed that changes in the overall environment had altered things.
Su Xi nodded again, then ignored Lu Wuyai and looked at the ancient goat painting in front of her, once again falling into a mysterious feeling.
Lu Wuyai looked at Su Xi. To make the experimental results more certain, he took another picture of a fox to Jin Xilu and asked her to try it as well.
Therefore, Kim Seok-rok also discovered that he could enter a state of concentration, and at a very deep level.
"If you keep the ancient painting, you can use the time to meditate and exercise."
“I know.” Gu Yuxin nodded, her face resolute. She knew that Su Xi and the others were in excellent health, and the source of everything that had changed was these ancient paintings.
The magical ancient paintings, the mysterious meditations... Lu Wuyai often wondered what kind of magical items these were that could change a person's physical qualities in this way.
Previously, when oxygen levels were low, the progress in improving physical fitness was very slow, but things are different now. The time required to enter a meditative state is clearly different.
From that day on, viewing ancient paintings became the most important thing for everyone, including You Li. She also unexpectedly discovered that when she entered a meditative state, she could even feel the heartbeat of the fetus in her womb. It was a miracle. This magical journey deepened the bond between mother and child.
And so, seven days passed in a row.
During this period, Gu Yuxin monitored the air quality three times a day—morning, noon, and evening—and found that the oxygen content in the forest fluctuated within the normal range without any upward trend. This reassured the people in the cave.
During the day, their main activity is mining ore. At the same time, they also clear weeds from the rocky hills to keep the environment clean.
Da da da.
At dawn, the sound of machinery could be heard from the rocky hill.
Gu Yuxin was pushing one lawnmower after another, clearing away all the grass in the vicinity, revealing a large area of clean land to prevent the invasion of rodents, insects and ants.
In the forest on the other side, Gu Yuxin and Xia Qingming were cleaning the cowshed. Three cows had become pregnant in the past few months. Based on calculations of the gestation period and increased oxygen levels, the estimated due date was October.
At the cave entrance, Lu Wuyai was moving machinery, with five cultivation warehouses in the middle.
"Lu Wuyai, be careful." Gu Yuxin's voice rang out from inside the cave, repeatedly reminding Lu Wuyai not to touch the breeding farm.
“I know,” Lu Wuyai said, his ears still ringing.
The farm is situated on a pile of rocks. There are no large trees nearby. The sun shines brightly from eight o'clock until five o'clock.
As for the other three high-end planting warehouses, it's safer to place them in underground pits. In any case, generators can provide power, consuming at most some fuel.
Under the sunlight, Lu Wuyai looked at the small meatballs forming in the breeding warehouse. Recently, the possibility of successfully cultivating fresh meat has been increasing.
Because of the numerous failures, everyone concluded that only high-quality fresh meat cells could yield fresh meat with a high probability.
For example, Japanese Wagyu A5 grade is more likely to successfully breed fresh meat than A1 grade.
"This thing is really amazing," Lu Wuyai thought to himself.
On the other side of the farm, Rou Rou was also lying on the ground. The little guy had recently learned to sit, but couldn't hold it for long. He looked like a short, chubby person, and seemed very innocent.
Rou Rou is always accompanied by an adult.
Woof woof
In the forest, seven enormous wolfhounds ran, their manes standing tall, creating a very powerful impression.
"Go take a shower," Lu Wuyai said dismissively. The dog smelled really awful. There was a separate car wash area downstream from the swimming pool, where people could wash their cars on weekdays.
Over there, Su Xi and Song Xiaoyou were brushing the cow's hair. When they saw the wolf and dog approaching, they immediately put on their coats. They were very experienced.
Lu Wuyai was incredibly busy that day, and he spent several hours in a daze under the sunlight. When he opened his eyes, it was already completely dark.
Two pieces of A5 grade Wagyu beef were found in the five breeding pens, and the marble patterns on them looked very beautiful.
“Not bad either,” Lu Wuyai said with a smile. After all, he knew beforehand that the success rate of cultivating warehouses in the middle was only 20%.
Soon, Lu Wuyai moved the breeding warehouse back to the laboratory. The space here is now almost half the size of a football field. At the very center is an advanced semi-artificial operating table.
At this moment, Su Xi was undergoing a prenatal checkup, while Gu Yuxin was carefully examining the condition of the fetus with a blank expression.
Ten minutes later, all the checks were completed, and Yu Li was in good health with no problems.
"However, the increased oxygen levels might cause the fetus to be born earlier, so you should be prepared," Gu Yuxin reminded her.
Su Xi nodded. Recently, she could clearly sense the state of the fetus after it entered a meditative state. No one could provide much information about this.
"There shouldn't be any problems. Things like meditation can regulate one's emotions. Doing more of it when you have nothing else to do should only benefit you, not harm you."
As they were finishing their meal, a group of people sat around the table. It looked like a beauty pageant, but it seemed that Lu Wuyai was the only audience member.
Lu Wuyai hoped that such days could last forever.
......
Days passed, temperatures rose, and soon the hot summer arrived.
However, there is no cold pool inside the cave. The temperature could be quite high this summer.
"It has air conditioning, are you sure you want to install it?" Lu Wuyai asked. After all, this kind of machine could easily expose what's inside the cave.
"Besides, it's not very hot now, maybe we can find a second cold water pool," Su Xi joked.
But that's not what the speaker meant; that's what the listener did. Lu Wuyai thought about it and realized that perhaps he really could find a second Hantan.
“Or you could go to the cave where the cold pool was first discovered,” Lu Wuyai said to himself.
Early the next morning, Lu Wuyai took Su Xi and Song Xiaoyou and drove to the Deadwood Forest.
On the way, when Su Xi heard that Lu Wuyai was going to find Hantan, her eyes widened. She said, "Because of what I said yesterday, you won't be able to find Hantan."
Lu Wuyai nodded. Su Xi was right. It was because of something she said yesterday that he had the idea of exploring Hantan again.
"There's nothing there," Su Xi said speechlessly.
However, Lu Wuyai insisted on going to find it. The car drove into the withered forest. There was only one road leading to the Cold Pool Cave, which they found easily.
So, Lu Wuyai and Song Xiaoyou got out of the car, while Su Xi sat in the driver's seat, ready to provide support at any time.
"Forget it, I'll just use the land patrol robot to go in and check first," Su Xi said, worried that there might be wild animals in the cave.
In fact, the cave had been abandoned, and there was indeed no trace of other cold water pools inside. However, to Lu Wuyai and Song Xiaoyou's surprise, the cave was still quite refreshing.
“These stones are cold.”
Song Xiaoyou reached out to touch the stone, and the icy feeling from her fingertips sent a chill down her spine; it was unexpectedly cold.
Lu Wuyai also looked curious. When he came in, he could clearly feel the temperature difference between the inside and outside of the cave. It was just the difference between winter and summer.
Lu Wuyai took out a shovel and started digging into the soil under the cold water pool.
A few minutes later, the air temperature grew colder and colder. Song Xiaoyou even had to move to the center of the cave passage to keep warm.
As for Lu Wuyai, he was furious, shrank his neck, and continued digging.
Five minutes later, Lu Wuyai could no longer hold on. He led Song Xiaoyou out of the cave and quickly walked to the car.
"Did you bring any clothes?" Lu Wuyai asked Su Xi.
Su Xi looked confused, but she still pointed to the trunk. She remembered there were several cotton-padded coats in the car.
Soon, Lu Wuyai entered the cave again, wearing a cotton-padded coat.
Su Xi grabbed Song Xiaoyou and said, "Here's the thing. Could it be that Hantan has really been discovered?"
"I don't know, but start the car first, then turn around." After saying that, Song Xiaoyou also re-entered the cave, worried that Lu Wuyai might be in danger.
At this moment, the chill in the cave grew increasingly terrifying, making both Lu Wuyai and Song Xiaoyou feel somewhat apprehensive.
Lu Wuyai jumped into the pit and continued digging with his shovel. Five minutes later, the shovel broke, exposing some black stones to the air.
Wisps of cold, white air drifted out from here.
"It seems this is the source of the cold pool. Those icy liquids have accumulated over countless years to form." In an instant, Song Xiaoyou pulled Lu Wuyai away from there.
Song Xiaoyou was about to pull Lu Wuyai away when the cold air inside the cave was about to escape.
"Wait for me."
Lu Wuyai quickly wrapped his hands in his clothes, grabbed a handful from the ground, and ran out of the cave.
"Lu Wuyai".
Song Xiaoyou followed behind Lu Wuyai and turned pale with fright when she saw the cold air emanating from his palm.
Even wrapped in his clothes, the black gravel was cold enough to kill. After a while, Lu Wuyai could no longer bear it, so the car was ahead.
Lu Wuyai threw the clothes in and ordered Su Xi to drive quickly.
"What happened?" Su Xi asked curiously.
"Drive faster!" Lu Wuyai shouted. At this moment, he was sitting in the back seat of the car, and the cold air coming from the trunk was quickly spreading between the seats.
At first, Su Xi felt comfortable, but then the temperature inside the car kept dropping. If it weren't for the engine constantly heating up, she would have frozen to death long ago.
Finally, the car stopped on the rocky hill. Lu Wuyai and the other three escaped, their bodies trembling as they looked at the car covered in frost.
"I'll go get the flamethrower." Lu Wuyai quickly entered the cave, with Song Xiaoyou following closely behind. She went to the laboratory to find Gu Yuxin and asked her to prepare to take over the new Hantan.
Two minutes later, the people in the local cave came out, and Lu Wuyai, carrying a flamethrower, began to melt the tree trunks that had been frozen solid.
A large amount of water vapor rose up, and to everyone's surprise, it lasted for a full two minutes, melting the frost on a tree trunk.
The moment he saw the fog stop rising, Lu Wuyai hurriedly stepped forward, opened the trunk, and revealed what was inside.
“Let me do it.” Gu Yuxin put on a glove that looked like a chef’s baking glove.
At that moment, the clothes wrapped in black gravel were completely frozen, and Gu Yuxin had to use all her strength to separate them from the car.
Gu Yuxin took off the white, cold clothes and returned to the laboratory, immediately isolating the substance.
Even so, the temperature inside the cave continued to drop.
"It's actually colder than the cold water pool last time." Everyone's first thought upon entering the cave was to compare it with the cold water pool.
In the laboratory, Gu Yuxin carefully removed the black gravel and stored it on a special material.
This is a sturdy material used to package breeding barns. Gu Yuxin analyzed it further and discovered it was likely the molted skin of some kind of animal. Very peculiar.
When the gravel got into the animal's skin, Gu Yuxin tried to touch it with her hand and found that there was no problem at all.
"Sure enough, this skin peels very easily." A slight smile appeared on Gu Yuxin's lips. He had finally collected most of the black gravel.
“Never mind those three people.” Gu Yuxin pointed to the last three stones on the ground and divided them into an orchard, a vegetable garden, and a corridor.
In this way, these black stones, constantly breathing in the cold air, completely lowered the temperature inside the cave.
"Actually, there should be more of these rocks under the beach."
Lu Wuyai remembered clearly that there was something at the bottom of the pit he dug, and these black pebbles were only a small part of the truth inside.
"I'll put on warm clothes and try again."
Gu Yuxin peeled the remaining skin into a bag and handed it to Lu Wuyai, telling him to be careful.
This time, Su Xi and Song Xiaoyou went together.
After the car stopped at the cave entrance, Lu Wuyai and Song Xiaoyou were already dressed. After getting out of the car, they carefully walked towards the cave.
Before they even entered the cave, they could see that ice crystals covered the entrance, and the ground was a vast expanse of white. A terrifying chill emanated from within the cave.
"It is indeed more chilling than the last icy pool." Lu Wuyai could already feel a chill in the air.
Soon, the two entered the cave one after the other, always keeping a distance of several meters.
Because it was cold outside, the warm clothes seemed to provide extra warmth. Lu Wuyai walked resolutely, wearing a gas mask. His vision was somewhat impaired, but it didn't hinder his ability to see.
There were several frozen dead cats in the passage. It seemed that during the time Lu Wuyai and the others were away, this place had been visited by cat-like creatures again.
Unfortunately, all the cats and beasts that came in froze to death.
The cold air gradually clung to Lu Wuyai and Song Xiaoyou's clothes. Within a radius of several dozen meters, the two of them were already covered in a large amount of water vapor.
However, thanks to the warm clothing, neither of them felt any discomfort.
Finally arriving at their destination, Lu Wuyai quickened his pace, took off the backpack made of shed skin from his shoulder, and dug down into the soil along the leather.
