"Leng Shanhong?" Mo Yun felt that the voice was very familiar.

"It's me."

The woman who suddenly appeared took off her helmet and showed a pretty face. She looked in her twenties, with shiny black and medium-length hair, and her bangs fell down, covering her left eye. There was a tear mole under her right eye, with delicate facial features, looking crisp and neat and heroic beauty. Even if she didn't speak, her eyes gave people a firm and decisive impression.

"You lead the way," Connor said.

"Come with me." Leng Shanhong exchanged glances with Mo Yun, and obviously she could hear Mo Yun's voice.

The two followed Leng Shanhong's footsteps and hurried into the underground base under the cover of flames.

"Buzz--"

A gentle roar sounded, and the thick cement walls closed again, isolating the surface of the ground like a plant forest from the base. The sound of flames burning leaves outside and the roar of the aircraft engines disappeared.

In the darkness, Leng Shanhong turned on the flashlight.

Yellow light column pierces the darkness.

"Why are you so slow? Our oil reserves are insufficient." She asked in a low voice.

"Dr. Kawaguchi was infected with phytochemical disease, and we dealt with this matter," said Mo Yun.

"Oh." She nodded, and didn't say much.

Mo Yun knew that she was similar to her situation - she had just come to this world and had no idea about her identity and the surrounding situation. Now she should have also learned some information, but due to the many people around her, it was inconvenient to communicate with him.

"I haven't seen you for many years, and you are still so hot." Connor, a young man with brown hair and red eyes next to him, said with a smile, and at the same time, he hooked his right hand and an orange flame ignited from the tip of his index finger, instead of a flashlight, illuminating the surrounding space.

"You seem to be doing well," Leng Shanhong said.

At this time, everyone had already walked along the slope into a spacious and open space. The layers here are clear. Looking down from the platform at the top, you can see that the base is roughly divided into four floors. Various passages are interlaced and complex, and guards wearing black combat uniforms walk by and patrol vigilantly. Each entrance and exit has a dedicated person for physical examination.

"The fourth underground floor is the rest area, the third floor is the leisure area, the second floor is the office area, and the first floor is the combat area and training area." Leng Shanhong introduced.

"Brother Yun, what should we do now?" Connor turned to Mo Yun, "Now Dr. Kawaguchi is dead. Logically speaking, we no longer need to continue pursuing it. Why not go back to the headquarters?"

"Since you've all come here, let's continue checking." Mo Yun said calmly.

"Is this really necessary?" Connor disagreed.

"Plant disease has threatened all of us. Although according to the current situation, people like us with special constitutions and abilities can be immune to the parasites of plant spores, if all ordinary people die, we cannot survive alone. There is an old saying in the East that where will the skin be attached without hair? You should understand this principle." Leng Shanhong said.

"That's right." Connor nodded.

Mo Yun looked at the girl in front of him thoughtfully. She happened to see her. The two looked at each other and nodded slightly. He had already discovered that the task in the lower left corner of his vision had changed, and she must have noticed it too. The line of eye-catching small words had become:

Task: Solve phytochemical disease.

"Solve phytochemical disease?" Mo Yun's eyes narrowed slightly. In the survival game, he was not sure what kind of outcome he would encounter if he did not complete the task, but he thought it would not be very good. But this task of solving phytochemical disease seemed to be a bit difficult. He already understood that this was a global crisis, with billions of people all in threat, and plants in the warning area were still evolving, which made the already confusing situation more complicated.

"Do you have any clues?" he asked directly.

"Maybe there." Leng Shanhong said, "is a survivor. He once mentioned that he knew the source of the disaster. But because there are too many statements about the source of phytochemical disease, we cannot be sure of it."

"Then start by investigating the source of phytochemical disease."

"Okay, it seems that this is the only way at the moment." Leng Shanhong said.

Mo Yun turned to Connor, "What about your opinion?"

"I'll listen to Brother Yun." Connor shrugged.

"Okay, let's go and visit that survivor now."

The three of them walked together, Leng Shanhong walked in the front. They walked through the intricate underground corridor and headed to the lower level.

Ten minutes later, they arrived at the residential area on the fourth floor of the underground. Here, Leng Shanhong led the two to visit a survivor, an old man in his sixties who lived in the room on the bottom floor of the underground. When passing the corridor, Mo Yun noticed that people's faces were full of sorrow and no smiles.

"Can you tell me what happened before coming here? About the source of those plants." Leng Shanhong asked.

"Please sit down." The old man's head is covered in white hair, and the wrinkles on his face also reveal traces of time. "I'm sorry I have nothing to entertain you."

"It doesn't matter."

The three of them sat down one after another. The room was not big, about twenty square meters, and the living room was only ten square meters, which was very narrow. In order to save electricity, the lights in the room were very dim. The old man sat behind the coffee table, staring at the visiting three people with turbid eyes. Perhaps because the underground ventilation was not good, the three people's expressions were a little unnatural.

"What do you want to know?" asked the old man.

"What job did you do before?" Mo Yun looked at the old man.

“I do cleaning for a hotel.”

"When did you first know that plant? How did you hear it?"

"At that time... about a few weeks ago, we welcomed many tourists on the island. Because this place was originally an island, and the climate was warm and humid, and there was a large area of ​​sand, there were many people coming to vacation. At that time, we had a lot of guests in the hotel, and sometimes we were too busy..." The old man said slowly.

The old man's turbid eyes stared at the void in front of him, his tone was a little emotional, as if he had returned to that past years. Mo Yun thought, maybe after he got old, he could not create new memories, so he could only rely on those memories of the past to live. Is this a kind of sorrow or a kind of happiness?

"One day our hotel received several foreign tourists, three men and two women. One day, while I was cleaning next to the swimming pool, I heard them say they were going to explore the island..."

"Wait, why do you remember so clearly? According to common sense, there are so many guests in your hotel, and it is very common to go out for a trip. Why do you remember only a few of them?" Connor asked.

"Because a few of them are very rude." The old man sighed. "As soon as I walked over, they told me to get out. I thought I had dirty the floor and said that there was a strange smell on me."

"What then?" Leng Shanhong asked.

"After two days, one of the women suddenly ran back covered in blood and said that his companion had died on the island." The old man said, "It caused a lot of sensation at that time, and even the guards stationed on the island were dispatched. But soon the phytochemical disease broke out, and everyone was only concerned about running for their lives. The island was in chaos, and no one cared about those tourists anymore. They were all concerned about leaving themselves."

"Where is the female tourist who escaped?"

"I died that night."

"It was only after she came back that phytochemical disease broke out." Mo Yun concluded, "that is, it was very likely that she had spread the plant spores all over the world."

"That's right." The old man nodded slowly.

...

"If the island base was the first place to break out of graft disease, then the source of everything might be here." Mo Yun said on the corridor outside the residential area after leaving the four underground floors of the closed and depressed space.

"What about our next goal?" Leng Shanhong asked.

"If the source is on the island, should we explore it?" Mo Yun frowned, "But we are not familiar with the situation on the island, and even if we find the source, it is useless. The spores have spread all over the world. Even if we clean up the source, nothing can be saved."

"So... it's better for us to go back to the headquarters," Connor said.

"Dr. Kawaguchi said that if you can find a way to adapt to plant spores, you may be able to develop a vaccine to completely solve this problem." Mo Yun thought for a while, "But do you know who can be immune to this spore?"

"People with special constitutions and superpowers can be immune." Connor shrugged. "Their blood activity is high. Once the spores enter the blood, they will be killed or assimilated. But ordinary people cannot do it, their bodies are too fragile."

"This..." Mo Yun frowned.

"Let's go to the office area first, you may need a rest, too," Leng Shanhong said.

"Okay." Conner nodded.

"Okay." Mo Yun said.

Following the iron ladder rotating upwards, several people entered the office area of ​​the Shangdao base. There are signal receivers placed here, which are the command and control center of the entire base. The base staff in purple uniforms are busy back and forth, and a generator is generating electricity next to them, making a dull sound of rumbling.

The atmosphere is a bit depressing.

"It's like the end of the world." Connor sat on the sofa with his arms in his arms.

"If we can't solve phytochemical disease, then for humans, it will be the end of the world." The girl turned her head and said coldly.

"But we have no choice now, right?" Connor spread his hands.

Leng Shanhong lowered her head.

"What is the room over there for?" Mo Yun raised his hand and pointed.

"That's the laboratory," Leng Shanhong said. "The base originally had a chemical laboratory responsible for studying local plants and mineral veins. After the outbreak of phytochemical disease, biologists were studying the plant, but they were also infected, so we sealed the room and completely isolated it."

“Are there any other places to study this plant on the island?”

"Some are a research institute, and they are also underground." Leng Shanhong nodded, "It is about dozens of kilometers away from here, and we are still in touch now. A lot of the news was passed on from them."

"Have you found anything?"

"Not much, I only know that this kind of plant is afraid of light. If it is in the dark, their activity will be greatly reduced. But this is the common characteristic of all plants, nothing special." Leng Shanhong took off her helmet, took off the bulletproof armor on her body, showing her beautiful figure curve. Her legs were slender and her height was nearly 1.7 meters.

She leaned casually against the wall next to her.

“What about the characteristics of this plant?”

"It takes about two days to develop from spores to mature bodies. The shortest is one day, the longest is one week, but the average time is two days. That is to say, as long as the spores are infected, they will die in two days, and there is no cure. Those things will penetrate deep into the human body and cannot undergo surgery."

"Do they parasitize other animals?" Mo Yun asked, "such as...monkeys or something."

"No, they seem to be interested only in humans."

"It sounds like nature is targeting us." Conner sneered.

Leng Shanhong tweaked the black bangs with her hand, "After the disaster, communications in many places around the world were interrupted, otherwise we might have more clues."

"You come out with me and let's talk alone." Mo Yun stood up.

"Okay." Leng Shanhong nodded.

Mo Yun looked back at Connor on the sofa.

"I understand, your private space."
