"Is there anything to eat?" Song Xuanshan asked weakly.

"Yes, yes, yes!" Lu Xue nodded again and again, and wanted to hand over the dry food she had with her to Professor Song, but was stopped by Xie Yun.

"I have hot porridge here. I'll give this to Professor Song. He doesn't eat when he's older. It's hard to digest dry food all of a sudden. Don't make any trouble." Xie Yun had expected it when she received the task. In this case, I prepared the steaming preserved egg lean meat porridge early and kept it fresh in my own space, which was just in time for use.

She took out a thermos cup from the space, which was full of warm porridge. When she opened it, the aroma was overflowing, which made Professor Song full of energy at once. Before it was too late, I drank porridge with a mug in my arms.

When Xie Yun took these porridges out, they froze them with an ice-type ability, reducing the temperature to a level suitable for mouthing, and they were still warm, so that Professor Song would not be scalded because he drank too quickly.

After the full pot of porridge was finished, Professor Song let go of the thermos cup with satisfaction, took a few breaths, and felt that he was alive again.

"You are the ones who came to save me." He turned to look at Xie Yun and asked in a trembling voice, with a hoarse voice that had not spoken for a long time.

"Yes, we are a rescue team sent by the mysterious base. Can you still walk now? If you can, please get up quickly. We will help you tidy up the research materials, and let's go." Xie Yun nodded and said.

She did not hesitate to directly say that the purpose of their trip was for Professor Song's research. Song Xuanshan also knew the value of getting special rescue. He nodded slightly, and with the help of Kang Limei and Lu Xue, he slowly Slowly stood up.

The torn quilt draped over Professor Song fell to the ground. Seeing that Professor Song was only wearing a thin shirt and trousers, Xie Yun frowned, and immediately took out a set of thick clothes from the space to put on him.

It's winter now. The temperature in the end of the world is extremely low, and this is still in the north. At this time, the outdoor temperature is minus 14 degrees, and even indoors, it is only about minus 89 degrees. This Professor Song is only wearing a thin shirt and trousers. At most, add a quilt, or starve in the absence of food. Just like this, he can last for so long, which shows how hard his life is.

wrong! Xie Yun felt it in the air with her hands. The indoor temperature in this laboratory is at least 15 degrees Celsius. Although it is still cold, it is unbearable. At least it will not freeze to death. , is still an ice type, no matter how cold the outside climate is, it has no effect on her, so she ignores the difference in temperature.

Moreover, there is electricity in this laboratory. After the end of the world, most of the power systems in the world have long been cut off. Even if there is a reserve power or generator, but there is no raw material, it will not last long. It has been more than half a year now. Xie Yun didn't believe that there was any electricity in this school, so the conclusion was that Professor Song came up with it.

"Professor Song, the electricity and temperature in this laboratory?" Xie Yun asked directly when she encountered something she didn't understand.

"Oh, you mean this, this is a generator that I made myself because I was afraid that I wouldn't be able to do experiments without electricity. This laboratory has heating, and if there is electricity, the heating can be turned on naturally, but the heating material of the heater is not enough. There are too many, so the temperature is lower." Professor Song pointed to a running instrument on the test bench and said.

He is a very kind and well-mannered old man. He doesn't have the weird temperament of ordinary talented people. Even if they know that Xie Yun and the others will come to save him because of the research results on him, they are still grateful.

He believes that no matter what it is for, it is already worthy of admiration and gratitude that people are willing to risk their lives to save him, so how can they still be dissatisfied? It's not that I don't know what's wrong, and it's a wolf-hearted and dog-lung.

Xie Yun looked in the direction pointed by Professor Song, and happened to see an instrument above it running. This instrument was a little familiar. She looked closer and saw a crystal nucleus floating in the unknown blue liquid. It is the energy provided by the crystal nucleus, which is then converted into electrical energy by this instrument.

Isn't this a crystal core generator?

Xie Yun was surprised at the bottom of her heart. The mysterious base had already developed a crystal nucleus generator. She had also seen it, but she didn't expect to see it again here. An expert in biomedicine, not a physicist, I didn't expect him to be so powerful that he could make a crystal nucleus generator by himself.

"This girl has space, right? Since there is space, it's easy to do things. You can help me take all these materials away, and then I will turn off all these instruments, and then you will help me install all the instruments and take them away. "Professor Song said to Xie Yun.

"Okay." Xie Yun nodded, turned around and went to the data cabinet. She didn't bother to load up the entire data cabinet, and then took away the instruments in Professor Song's laboratory, and then prepared to take Professor Song's people.

However, before leaving, Professor Song made another request to Xie Yun: "That girl, there are still some surviving students in this study, I know this is very embarrassing, but I still have to beg you guys with a thick face, you guys Can you also take them away, don’t worry, there are many students with supernatural abilities, although the level is not higher than yours, but they can also protect themselves, I beg you.”

Song Xuanshan has a sincere expression and a humble attitude. Even though he is a highly respected old professor who has invented vaccines that can benefit all mankind, he is just a teacher who thinks about his students at the moment.

This is an admirable teacher! Such a thought flashed through the minds of the people of the Blizzard team.

Professor Song devoted his whole life to medical research. He didn't marry a wife, and naturally he had no children. He came to teach at this school not only because he wanted to pass on what he had learned throughout his life, but he also liked to see the energetic students. Appearance, which made him feel happy from the heart.

In fact, what Xie Yun and the others didn't know was that the reason why Professor Song could survive so long after the end of the world was not only because of his own ingenuity, but also because of the surviving teachers and students in this school.

After the end of the world, they were trapped here because they didn't escape from this school in the first time.

Fortunately, the university campus is a small living area, with complete facilities, all kinds of supermarkets and canteens, and there are three canteens and several logistics storage warehouses in the school, which store a large amount of food and daily necessities. You know, These things were originally intended for use by tens of thousands of teachers and students in the whole school. The number is huge, enough for these surviving teachers and students to live happily for more than ten years.

Moreover, the only benefit after the end of the world is that the environment has become better, and the water sources and land have not been polluted. The surviving students, under the mobilization of the surviving teachers, have sorted out the land that was originally planted with flowers and plants in the school. Grow vegetables and fruits for them to eat and drink.

In an accident, they found Professor Song in this experimental building, but because there were a lot of zombies outside and their strength was not high, there was no way to rescue him. They could only let one of them run the fastest. People, when other people distracted the attention of the zombies, sent food and other materials to Professor Song, and even the crystal cores used by Professor Song to generate electricity were also sent by them.

After delivering the things, the students with the speed ability will leave again with the help of their classmates and teachers. They are incompetent and can't save Professor Song, so they can only use this method to help him.

Recently, because there was a fourth-order spider woman outside Professor Song's laboratory, no one of the surviving teachers and students in the school could beat her, so there was no way to send materials to Professor Song, and Professor Song also realized that they were doing this. No way, the zombies will only get stronger and stronger. One day, he and the teachers and students trapped in the school will all be killed by more powerful monsters.

But he also understands that the weight of these people is not enough for the big forces in the outside world to send strong men to come to the rescue, so he saves the rest of the food while stepping up his research on the subject at hand, and finally has some results. When the time came, he could not wait to send out a distress signal.

Because he understood that all their bargaining chips were his vaccine to prevent zombie virus, he focused on describing this vaccine in the distress signal, which made the subsequent address information unclear, but as long as the rescuers came, they had hope of life.

"You can rest assured that the heat detectors at our base have long discovered that there are more than 100 teachers and students surviving in this school. Our main task is not only to rescue you safely, but also to take away those survivors. "Kang Limei said solemnly to Professor Song.

"That's good! That's good! Thank you, thank you." Song Xuanshan smiled gratified and thanked him continuously.

When he was helped out by Lu Xue, he jumped when he saw dozens of mutant beasts playing happily outside, but he was comforted by Lu Xue, and he watched those mutant beasts get close to the little girl who was the captain. It was very difficult, so I felt relieved, and at the same time, I couldn't help but feel more confident that they could rescue the surviving teachers and students in the study.

Because there is a competitor of the Flying Tigers, Xie Yun did not dare to let Professor Song out of her sight, and only let a few team members protect him. She was afraid that the Flying Tigers hadn't left yet and lurked aside, waiting for them to relax their vigilance. If they came up to grab people, they would have to rescue the surviving teachers and students. Bring Professor Song. Having Professor Song as a living sign can also increase the credibility and make the mission go a little more smoothly.

With the help of a large number of mutant beasts, the zombies surrounded by the outer door are not to be afraid of. Under the brave attack of the mutant beasts, they directly contributed a lot of crystal cores to Xie Yun, and then spread the corpse on the ground. Xie Yun took Professor Song and the team members out of the front door swaggeringly.

After waving out the two cars, let Professor Song sit in the second row of Xie Yun's car, Dajin was lying on the roof with his baby daughter in his mouth, and the king and the princess sat on both sides of Professor Song. , the three team members sat behind Professor Song, Xie Yun was still sitting in the passenger seat, this time it was Lu Xue who drove the car, protecting Professor Song so tightly that not even a fly could fly in.
