In the distant darkness, there was a hill like shadow, which was moving towards her direction at a very slow speed, and mather immediately stopped with vigilance.

Although the shadow was huge, its speed was too slow - she put down the first-aid kit and waited for several minutes with her arms in her arms, before the huge shadow gradually approached and showed its original appearance in front of her eyes. As soon as she saw it clearly, matherton raised one eyebrow: "... What are you doing?"

It was Hu Changzai who came.

On his shoulder was a rope he had found somewhere, and the other end of the rope was tied to the unconscious haitianqing, who was dragging forward step by step -- this scene was like a chicken pulling a camel, so tired that Hu was always panting, and his eyes were bulging: "hoo, ha... Help, help..."

As soon as he looked up, he was silly first: "Mather, how did you get into this situation?"

There was hardly a good place in mather's whole body, either bandages or potions, and she couldn't even see her original skin color. She sighed helplessly, "there were too many wounds just now, so I went to the infirmary to deal with them first and took something I thought might be useful. Don't worry, it's all skin and flesh wounds... It's you - Chen Jinfeng was killed by me, but what's the meaning of dragging your opponent away?"

As soon as Hu Changzai's eyes fell on the first aid kit, he fell to the ground with a thud and waved weakly: "first, first cure him... He and we have a common enemy... Specific and physical, wait until I breathe and breathe well..."

Since he said so, mather also took out alcohol and needle and thread and simply treated Hai Tianqing's wound. After all, she fed the medicine again. She wiped the blood on her hand with a cotton cloth mockingly: "since I came to oasis, I've almost become a surgeon... OK, let him sleep here, and he can only carry the rest by himself."

Anyway, in terms of Hai Tianqing's physique, it's hard to move anywhere again - Hu Chang nodded, when a few coughs suddenly sounded in the distance, and then someone asked in a low voice: "... Is it mather?"

They looked up and staggered out of the night. It was Fang Dan.

Fang Dan's skin was covered with large bruises, without any wounds. But her face was very bad: "great, I can count on finding you -" before she finished speaking, her body was about to slide down.

Hu Chang held her fast with his eyes and hands. Mather hurriedly came to check her, and was surprised: "at least three of your ribs are broken! How can you walk around? It's too dangerous... Where's your opponent?"

Fang Dan squeezed out a weak and proud smile: "I'm still alive, of course he's dead."

With that, her eyes turned and fell on Hai Tianqing. At that time, she was startled: "ah! What's going on!"

Hu Chang hurriedly explained to her, and Fang dancai closed his mouth suspiciously. Mather did some emergency treatment for her. Seeing that her condition was not suitable for walking again, they simply held her and slowly lay down beside Hai Tianqing.

"Let's go to see the situation of Xiaojiu, and then we'll come back to you right away. Although there's no one outside, you'd better hide beside Hai cadre..." mather said softly.

Fang Dan nodded and leaned on his arm, which was as green and thick as a small tree trunk, and his expression gradually relaxed.

Seeing that she closed her eyes, mather and her husband didn't dare to delay any more, so they hurried to the cadre building.

"... I can't see. Fang Dan is also very powerful! What is her ability?" Hu Chang gasped and asked while barely catching up with mather's speed.

Mather paused at his feet and looked back at him in surprise: "I don't know. You two have been in the oasis for so long, I thought you knew..."

Hu Chang was stunned, but he didn't take it to heart -- when Fang Dan was better, there were many opportunities to ask.

After running like this for less than a minute, the cadre building is in the distance. The smoke and dust caused by the two people running all the way has long attracted the attention of several people in front of the building - "one, two, three... No, why are there three people here besides Xiaojiu? And Xiaojiu seems to be carrying something in his hand..." mather tilted his head suspiciously.

Although a person - what is in his hand—— Facing three people, Lin Sanjiu was not nervous at all; She saw the figure of mather from a distance, and even turned around and waved at her, shouting, "Mather, are you coming? Come here!"

Accompanied by dust and smoke, mather stopped at her side with doubts.

She looked at the three people opposite Lin Sanjiu. Among them, the little girl with cornucopia and the enchanting woman, she had met face to face. It was Xu Xiaoyang and Xiao Hui. The other is a middle-aged woman in a white coat. She has short hair and looks very strange. She has never seen it before.

After thinking for a while, mather still asked the most concerned question: "... Where was the rabbit caught and can it be eaten?"

I can't blame her. She hasn't eaten meat for 28 months.

"I'm not food! You stupid x woman!" Although his ears were still in others' hands, the brown haired rabbit, who felt that his allies had arrived, resumed its rude tone: "don't look at me, get away!"

"What's going on?" It was also the first time for mather to see a talking rabbit. She was stunned and asked, and suddenly remembered that there were people standing beside her: "and who are they?"

While talking, Hu Changzai also ran close out of breath - Lin Sanjiu didn't answer her, and asked with a little solemnity: "are you all right? How are the other three cadres?"

As soon as he asked this, the people opposite also pricked up their ears.

"Except for haitianqing, the other two are dead." As soon as mather raised his chin, Yu Guang glanced at the three people with unknown intentions on the opposite side. Seeing that they all changed their faces, she added in a low voice: "Fang Dan was seriously injured, and now he is recuperating with Hai Tianqing."

Seeing Lin Sanjiu's expression, Hu Chang hurriedly inserted, "I'll explain this later... By the way, what about you, Xiaojiu? Aren't there still two cadres?"

"Well, this is one of them -" Lin Sanjiu raised his arm and shook the rabbit in his hand, "come on, say hello."

The rabbit kept silent with a gloomy face.

"So the legendary rabbit cadre is really a rabbit?" Hu Chang screamed.

"There's another one. Nobody knows anything behind it." Looking at the way they opened their mouths, Lin Sanjiu shrugged.

Before the two of mather reacted, Xu Xiaoyang sighed incredulously, "you are so few that some people haven't strengthened their ability. I really don't understand how you beat the cadres?"

"Oh, yes," she seemed to finally remind Lin Sanjiu of this sentence. She raised her chin across the room and said, "Captain Xu just said she had a request, and there was still time to say it. Since you are also here, let's listen together."

Xu Xiaoyang listened, lowered his eyelids and looked gloomy. At this time, he didn't look like a child at all. Her eyes turned on the middle-aged woman beside her, stretched out her hand to hold the corner of her dress, couldn't help sighing low and saying, "I hope... You don't hurt my mother."

"Your mother -?"

Xu Xiaoyang nodded, and the cornucopia slipped next to her drooping face: "I'm Professor Bai's daughter."

Their eyes immediately focused on the middle-aged woman. Xu Xiaoyang's voice was almost inaudible: "my mother, she... Is also a member of the high-temperature adaptation drugs. She has no potential value, so she has not evolved any ability. But if you want to hurt her, I will die -"

"So she is Professor Bai?" As soon as her tone was firm, Lin Sanjiu interrupted, "we actually don't know who Professor Bai is... If you didn't say it just now, I'm going to let her come."

Xu Xiaoyang quickly raised his head, his facial features frozen in a regretful expression.

"Now that I know, I can't let her go easily. At least not before I ask her clearly." Lin Sanjiu nodded at her apologetically, then turned around and asked, "why do you feed degenerate species?"

Xu Xiaoyang shivered and couldn't help talking. Professor Bai suddenly patted his daughter on the shoulder and stopped her talking.

The brown rabbit in her hand was stunned, and then hissed, "what nonsense are you talking about -"

"... when I went down this road, I knew I had to go down alone." The voice of the middle-aged woman opposite interrupted it, and the brown rabbit looked at it foolishly.

Professor Bai turned his eyes to the direction of oasis dormitory building. After looking at it for a long time, he whispered: "... Yesterday, several children about the same age as Xiaoyang entered the greenhouse for the first time."

Lin Sanjiu was stunned and didn't know what she meant.

"They are about to learn biology, so the teacher took them and planted some radishes in the greenhouse. Tomorrow, next week... They will wait for a period of time, and these radishes will gradually grow... Just like these children."

Professor Bai turned his eyes and smiled gently. Several lines fell deeply on his mouth.

"There are 1600 people living in the five buildings over there. They are male and female, most of them are young and middle-aged, and there are countless tomorrow that belong to them... Oasis is a model of post reconstruction human society, and they are the kindling of human continuity."

Taking a deep breath, Professor Bai's face lit up with a gentle smile. "In order to preserve these fires and let mankind continue to multiply, even if I can only walk in the dark forever, I have no complaints."

Hu Chang was stunned, nodded to his companions, and whispered, "everything she said came from the bottom of her heart."

"What does this... Have to do with the fallen species?"

Professor Bai's eyes turned around on them: "if I say, the reason why oases can have today's scale is all due to degenerate species?"

The three people on the opposite side were surprised and looked at her speechless.

"Why do people evolve? This has puzzled me for a long time. Are those who evolve better than ordinary people and should live better? But the fact is not like this... You are only a small part of the variation. It is the 1600 ordinary people over there who really need to reproduce. What I have done is to sacrifice a small part and save the majority."

Xu Xiaoyang tightly pursed his lips and lowered his head.

"It's a shame to say, but most of the technology that saved the oasis people didn't come from me. A degenerate plant gave me the technology of high temperature resistant crops, the medicine for high temperature adaptation, and the way to collect water... What he and his companions needed was just some naturally evolved people."

"Obviously, degenerate species also need to evolve... And their way of evolution is to suck evolutionary humans."

Her tone was still soft, and the smile on the corners of her mouth was still a little gentle helplessness; However, in her eyes, there was an increasingly prosperous, almost crazy light.

It took a long time for someone to speak.

"... that is to say, you lured countless natural evolutionists with the living conditions of the 'oasis' as bait, and then, just as you treated us at that time, you told them to degenerate and die?" Lin Sanjiu's voice was very low.

"The specific affairs in this regard have always been arranged by cadre Chen. It turns out that you have done such a task once..." Professor Bai nodded, looked at them and said sincerely, "on behalf of oasis compatriots, I thank every naturally evolved person for their sacrifice."

Lin Sanjiu, who had been lowering his head, suddenly burst into a rage: "you idiot woman -!" Then she clenched her fist and pounced on it.

——Meanwhile, Fang Dan, lying beside Hai Tianqing, suddenly moved. She seemed to hear something, slowly opened her eyes and looked at the man who came out of the night. She smiled: "... It's you. I knew you would be fine. Is everything going well?"
