“This person can leave at a speed of 20 meters per second.” Lu Wuyai was shocked by this answer.

Perhaps it was because the time interval was too short. Lu Wuyai recalled the black dots he had noticed while watching the video. Gu Yuxin calculated the movement speed of these black dots, and it happened to be this frequency.

This speed surpasses that of many hunting dogs. Although Lu Wuyai sometimes runs faster than a general, that's due to his short-term burst of speed. As for long-term stamina and endurance, he is completely incomparable to animals.

Lu Wuyai took a deep breath and looked at the peaceful forest, feeling that something big was about to happen.

"It can't be an infectious disease."

Lu Wuyai suddenly remembered the plant extract that Gu Yuxin had been researching, but in order to obtain the third stage of the drug, he had to find a plant called calamus.

If this is indeed an infectious disease, this extract will be the only thing that is useful to them.

Back at Shiqiu, Lu Wuyai rearranged the traps, secretly remarking that his opponent was incredibly lucky; the grenade hadn't been triggered at all, otherwise, they would have been in serious trouble.

"A trap is definitely not the safest option," Lu Wuyai thought anxiously. Every time an emergency occurred, he would consider the worst possible outcome.

"How about we find another refuge?" Lu Wuyai asked himself.

Today, there are many survivors on the deserted island. In the future, the living space around the island will likely be squeezed, and conflicts will continue to arise.

Lu Wuyai finished tidying up the traps and checked the pool again. The water quality was fine, and he could see a large number of crucian carp and silver carp at the bottom of the pool.

When he returned to the cave, Lu Wuyai saw that Jin Xilu was already awake, wearing a semi-transparent nightgown and drinking water from a cup. As for the other women, they were still asleep.

Seeing the figure vaguely visible in the other person's pajamas, Lu Wuyai couldn't help but recall his last trip to the beach, and the fire in his heart was instantly ignited.

Before Jin Xilu could react, Lu Wuyai strode over, picked her up, and couldn't help but stroke her with both hands.

At this moment, Jin Xilu was terrified, like a cat that had stepped on its own tail. After a difficult struggle, she realized the vast difference in strength between them, and her entire body instantly became as soft as water.

Lu Wuyai pressed himself tightly against the other man, feeling the size of his chest, and his breathing immediately became rapid.

"Lu Wuyai, I... I'm not ready yet." Jin Xilu blushed and tried to create distance between them.

But Lu Wuyai, blinded by desire, completely ignored Jin Xilu's resistance.

Amidst gasps of surprise, Jin Xilu's clothes fluttered up like butterflies, her fair skin turned as red as blood, and her sexy body was unbelievably beautiful.

Suddenly, Lu Wuyai felt a sharp pain in his ears, followed by a buzzing sound, and then a huge explosion resounded on the rocky mountain.

It was as if someone had poured a bucket of ice water on him, and Lu Wuyai's anger was extinguished. He didn't even have time to consider Jin Xilu's feelings before running straight out of the cave.

Upon reaching this point, Kim Hee-ro's legs went weak and she almost knelt down, but she hurriedly picked up her clothes from the floor and immediately went into the private room.

A few dozen seconds later, the women emerged one by one from the other carriages. The explosion had left them all feeling somewhat uneasy.

Lu Wuyai had already appeared on the rocky hill, gun in hand. He glanced at the area near the cave entrance where grenades had been planted. Suddenly, several dark craters appeared there.

"What's going on?" Su Xi and the others rushed out. Lu Wuyai glanced back, his gaze lingering on Jin Xilu for a few seconds.

cough cough

"It looks like a grenade was detonated," Lu Wuyai said.

But the key point is that no one appeared nearby.

Lu Wuyai looked around and spotted several familiar footprints, filling him with immediate fear.

Undoubtedly, it was that same person with bloodshot eyes who came to the stone mountain again, but Lu Wuyai didn't know whether the other party had deliberately triggered the bomb or accidentally triggered the mechanism.

While rearranging the traps, Lu Wuyai explained what he had just discovered.

Upon hearing this, the women looked terrified.

"Are you sure it's a person?" Gu Yuxin asked.

Lu Wuyai nodded. Although he had only seen those eyes, he was certain that the other person was human, perhaps infected with some kind of disease.

“What you’re saying is possible,” Gu Yuxin said. “Some diseases can indeed greatly improve a person’s overall health, and the radiation that occurred before might have been some kind of mutated virus.”

Gu Yuxin's words were shocking. If the virus had indeed mutated and spread, they would definitely be affected on the deserted island. At that point, isolating themselves from the world wouldn't be so simple.

"The third stage of plant extracts is still missing one last traditional Chinese medicine: calamus." Everyone immediately understood the meaning behind Gu Yuxin's words.

But are there things like calamus on a deserted island?

After the traps were rearranged, it was already dusk, and the sunlight, tinged with an orange hue, shone on the people, making them feel exceptionally warm.

Summer has passed, and the weather doesn't seem as hot as before.

That night, Lu Wuyai lay alone in bed, thinking about the events of the day, unable to fall asleep for a long time.

Over the next two days, Gu Yuxin prepared equipment for the upcoming trip, most of which was related to solar energy.

For this reason, Lu Wuyai and the others resumed their routine of not returning home for the next two nights. As night fell, they searched for the plane that had made an emergency landing and obtained a large amount of power equipment.

The forest on the deserted island remained restless at night.

On the first night, Lu Wuyai and his team followed their previous route to several emergency landing aircraft. At the same time, they also looted a large quantity of electronic products, from complex circuit boards to tiny screws the size of grains of rice, almost completely destroying the planes. The cockpits were razed to the ground.

However, large numbers of wild animals appear in the forest from time to time, even more frequently than in the height of summer.

Lu Wuyai was worried that this long journey might not be safe.

The three months following midsummer are a time for animals to prepare for winter, especially carnivores. The bloody storms in the forest will certainly affect them.

Therefore, they must hurry and make sure everything is in order.

Inside the multi-purpose vehicle, Su Xi and Jin Xilu were constantly operating a drone, searching for any aircraft they hadn't found in the forest. Since they were going on a trip, they needed to gather more supplies.

You can never have too much material stuff. Even if you don't need something for the time being, you can sometimes exchange it with others.

Early that morning, Jin Xilu finally found a plane that was almost completely covered by forest.

When they reached the plane, a group of wolves appeared around them, growling at the vehicle and even tearing through its exterior amidst Lu Wuyai's pained expression.

With a bang.

Lu Wuyai suddenly opened the car door, instantly stunning a wild wolf.

In the following time, everyone set up crossbows in front of the car door and used their night vision to drive away the nearby wolves.

Half an hour later, the wolf pack dispersed, and Lu Wuyai and the others parked their vehicle in the cargo hold of the plane.

Lu Wuyai got out of the car. Because of what had happened last time, he immediately went to check if there were any survivors on the plane.

A few minutes later, Lu Wuyai knocked on the door of the cabin and told the others that everyone who stayed inside was dead.

When the cargo hold was opened, it was empty. Clearly, someone had gotten in first.

"Alright, let's hurry up and get the parts out of the cockpit," Gu Yuxin said, yawning as she couldn't help but yawn; she was exhausted from staying up all night.

Later that night, they discovered three more planes, all of which had been loaded with cargo.

When we returned to the hill, it was already broad daylight.

The situation was similar the following evening. Gu Yuxin stayed in the cave, preparing materials for the journey.

And just like that, another week passed without us even realizing it.

During dinner that day, everyone was discussing their travel bucket list. Finally, Lu Wuyai led the group, accompanied by Su Xi and Song Xiaoyou. The three of them formed a team to find Iris.

Unexpectedly, the next day, Su Xi's aunt was in excruciating pain and was definitely not fit for a long trip. In the end, Jin Xilu volunteered to join the team.

Seeing Lu Wuyai's burning gaze fixed on her, Jin Xilu felt her heart pound involuntarily, and she regretted her decision.

Soon, Lu Wuyai emerged from the forest in a military-green pickup truck. The fuel tank was full, and he had also brought an extra can of gasoline, enough to travel a long distance.

Furthermore, the addition of a Molloy-designed solar panel to the sunroof allows for easy upgrades to the car's systems. Even without gasoline, it can still start as long as the weather is good.

After getting into the car, Lu Wuyai waved to everyone and, taking advantage of the cool morning weather, drove towards the depths of the deserted island.

This time, the search for Acorus will not be safe. They have given them a two-week deadline. If they cannot find the calamus within two weeks, they will prepare to return to Stone Hill.

Gu Yuxin was also preparing for the worst. If she couldn't find calamus, she would use other herbs instead.

Therefore, this time, Lu Wuyai and the others also undertook the task of finding other Chinese medicinal herbs.

Inside the car, Jin Xilu and Song Xiaoyou sat in the back, flipping through the atlas Gu Yuxin had given them before she left. It contained hundreds of different types of Chinese medicinal herbs, but only a small portion of those grown in the cave.

After watching for a while, Song Xiaoyou opened the car window and scanned the flowers and plants along the way.

She and Lu Wuyai consumed plant extracts at various stages, resulting in a significant improvement in their physical condition. In particular, their eyesight improved dramatically, becoming like scanners, quickly capturing images in their brains wherever they went.

On this day, Lu Wuyai drove around the deserted island non-stop, stopping dozens of times along the way, and harvested a total of 23 kinds of medicinal herbs, including calamus.

Lu Wuyai clicked his tongue in surprise and said, "I didn't expect that I would find calamus in less than a day after leaving home."

"Should we go back?" As he spoke, Lu Wuyai turned the car around, preparing to reach Shiqiu before dark.

But Song Xiaoyou said, "No, now that we're out there, we should go find the raw materials for the fourth stage of plant essence."

"The main materials needed for the fourth stage, in addition to the Polygonum multiflorum we discovered, also include asparagus and Phellodendron amurense."

"Especially asparagus, wild asparagus is almost impossible to find, and on such a deserted island, artificially cultivated asparagus will never appear."

Lu Wuyai rubbed his nose and finally agreed with Song Xiaoyou's statement. Now that they were out, he should indeed prepare for the fourth stage of the plant essence.

At dusk, the vehicle stopped in a dense forest.

Song Xiaoyou packed her luggage and prepared for tonight's dinner in advance. Jin Xilu drove nonstop into the nearby forest, not even having time to go to the toilet.

As soon as Jin Xilu found a suitable spot, she saw Lu Wuyai walking over from not far away.

The two exchanged a glance, their hearts racing involuntarily, which made Lu Wuyai subconsciously look in the direction the car had come from.

The forest was very dense, and there was no one around.

Jin Xilu blushed and told Lu Wuyai that she needed to use the restroom.

Lu Wuyai smiled awkwardly and turned around. Soon, he heard the gentle sound of flowing water. The sound was like a cat nestled in his arms, tickling his heart.

Finally, when the sound of water stopped, Lu Wuyai turned around and found Jin Xilu with her back to him. A simple t-shirt couldn't hide her beautiful figure.

On the way back, Lu Wuyai followed behind Jin Xilu. He was probably a little absent-minded. He lost his footing, fell forward, and pinned Jin Xilu to the ground.

Lu Wuyai's hand happened to grab a certain protrusion, a feeling that would drive any man crazy.

What's more, Jin Xilu blushed, and the twilight light added a strange atmosphere to the forest.

As the strength in his hands gradually increased, Lu Wuyai's eyes became bloodshot. His body pressed tightly against Jin Xilu, feeling her touching and delicate body. There was only one thought in his mind.

Seeing that Lu Wuyai was gradually losing control, Jin Xilu suppressed the pounding in his heart: "Lu Wuyai, no, not here, okay?"

"Then, where is it?" Lu Wuyai almost roared.

Jin Xilu's face turned bright red, almost bleeding. Just as she was about to say something, the sound of a tree branch breaking rang out.

The two immediately got up from the ground, their previous expressions vanishing instantly.

Jin Xilu quickly tidied her clothes. The next second, the two of them saw Song Xiaoyou walk out from the corner, looking at them with a puzzled expression.

The atmosphere froze immediately upon Song Xiaoyou's arrival.

However, seeing the other person's confused expression, Lu Wuyai and Jin Xilu knew that she had not seen what they had just done.

Lu Wuyai broke the silence, saying, "Are you almost done? Why are you here?"

"Almost done. I noticed you two hadn't arrived yet, and I was worried something might have happened to you." Song Xiaoyou blinked, feeling that Jin Xilu was acting a bit strangely.

But Lu Wuyai started urging him on, and he was so hungry that his chest was pressed against his back.

On the way back, Jin Xilu's cheeks were flushed, and her heart was still pounding uncontrollably. After all, she had never had a boyfriend for this long before, and only Lu Wuyai truly appreciated her beautiful figure.

“He already has girlfriends, more than one, and his relationships are too messy.” Jin Xilu touched her face, thinking to herself that she could practically count the number of women Lu Wuyai had been with on one hand. If she said she didn’t mind, she would definitely be lying.

But if Lu Wuyai forced herself on him again, she wouldn't be able to resist. First, she didn't dislike Lu Wuyai; in fact, she even liked him a little at first. Second, she also wanted someone to protect her.

On a deserted island, men always seem to have an innate advantage. However, Lu Wuyai didn't have many bad habits. Even compared to other men, this man's mind was undoubtedly much healthier.

Back in the car, Lu Wuyai looked at the noodles cooked by solar power and smelled the aroma of sausages in the air. His stomach was already starting to rumble.

After dinner, dusk completely enveloped the forest.

Lu Wuyai set up a tent on the cargo pile of the pickup truck, just big enough for two women to sleep in. As for himself, the back seat of the pickup truck was spacious, and Lu Wuyai was very comfortable lying on it.

The night passed quietly like this.

The next morning, Lu Wuyai vaguely heard noises in the forest. When he opened his eyes, he happened to see Song Xiaoyou returning from her bath. Her fair cheeks were bathed in the golden morning sunlight, and the surrounding green leaves accentuated her lotus-like elegance.

Seeing Lu Wuyai staring at him, Song Xiaoyou's face instantly turned deep red.

At this moment, Kim Hee-ro also got out of the car, and the trembling in her chest seemed a little stronger than yesterday.

Lu Wuyai swallowed hard, secretly assuming that he was surrounded by such S-class beauties.

After quickly packing up, Lu Wuyai continued driving, but it seemed his luck had run out. They didn't find a single herb all morning.

After noon, they changed direction and headed deep into the forest. Lu Wuyai did his best to find a drivable mountain road. Fortunately, with a pickup truck, even some complex terrain could be traversed.

At three o'clock in the afternoon, the car stopped in a dense forest. Song Xiaoyou got out of the car and dug up two old ginseng roots at the foot of a nearby mountain. This was her first harvest of the day.

"It wasn't all for nothing after all," Lu Wuyai sighed.

Song Xiaoyou got into the car, and the convoy set off again, continuing its journey deeper into the deserted island.

Before dark, they reached a foothills where the vegetation was not very dense, the ground was dry, and there was no animal droppings nearby, so everything was relatively safe.

After parking the car, Lu Wuyai used the batteries stored in the solar panels during the day to start cooking, while the two women took a small amount of fresh water from the cargo box to wash their faces.

When leaving home, all resources must be used as ruthlessly as possible.

In the shady spot at the foot of the mountain, Lu Wuyai built a campfire and roasted the wild rabbit he had killed that afternoon, sprinkling it with cumin and chili powder. The enticing aroma made people temporarily forget the day's fatigue.

An hour later, the rice in the rice cooker was fully cooked.

After a hearty meal, all three of them were extremely satisfied. Just as they were about to rest, Song Xiaoyou suddenly pointed to a distant mountain peak and whispered, "There seems to be something glittering on the mountaintop."

Lu Wuyai squinted, even taking out binoculars to look in the direction Song Xiaoyou was pointing, but found nothing.

“Okay,” Kim Seok-rok asked again.

Song Xiaoyou nodded. She did see something flashing on the mountaintop.
