After ending the call, Gu Yun dug out a textbook he hadn't read for a long time, put on his Confucian uniform, hugged Xiao Bai, and was about to start the inverse astrolabe when his cell phone rang again. Could it be that Teacher Zhou is still worried? Gu Yun casually answered the phone, "Hello?" "Gu Yun, why is it so difficult to call your phone?" Professor Zhang complained on the other end of the phone. "Uh, Professor Zhang, I just came back from Africa and my phone is out of battery!" Gu Yun had to tell a little lie. "Okay, I got it!" Professor Zhang did not go into details, but asked: "Are you busy now?" "Huh?" Gu Yun was surprised for a while, but then he realized it and said in surprise: "Has the antidote been researched? "Ahem" Professor Zhang coughed in shame and said with some embarrassment: "Although there has been some progress in the antidote, it is not as good as the green crystal you gave me. The research on that green crystal made a major discovery!" "Then I'll come right away!" Although Gu Yun regrets that the antidote has not yet been developed, at least there is some progress. Moreover, the research on the green magic core has made a major discovery, and it is a major discovery coming from a veteran like Professor Zhang. It is exciting to think about it! "Okay, I'll wait for you in the laboratory!" Gu Yun took off his scholar uniform, hugged Xiaobai out of the door, and took a taxi to Professor Zhang's laboratory. When we arrived at the place, Professor Zhang went out to greet him personally. As soon as he saw Gu Yun, he said excitedly: "This discovery may cause a global sensation. Where did you find that kind of crystal in Africa?" "That one was found by accident!" Gu Yun agreed casually. , and then asked: "Where is the research report?" Seeing that Gu Yun was unwilling to say more, Professor Zhang stopped asking and invited: "Let's go to the laboratory!" Gu Yun came to the laboratory with Professor Zhang Sitting down in a small office. Professor Zhang took out a stack of more than 40 pages of reports and handed them to Gu Yun and said: "All the research reports are here, 46 pages in total, at least one major discovery!" "At least one?" Gu Yun was surprised. , open the report. Professor Zhang pointed to the summary on one page and said: "Just look at this summary. You can't understand the specific data!" "Oh!" Gu Yun followed Professor Zhang's guidance and saw the specific and important information. Results. "The crystal can slowly dissolve in water. When the concentration of the aqueous solution reaches 0.37%, it can effectively eliminate a variety of toxins in the body of mice and repair the affected cells; when the concentration of the aqueous solution reaches 1.28%, it can kill mice Various viruses in the body and excrete them without destroying infected cells and tissues When the concentration of the aqueous solution is lower than 1.75%, it is harmless to mice; when the concentration of the aqueous solution is higher than 2.47%, it will kill the mice. "Cancer cells, but it will also cause damage to other healthy cells of the mice" "Is this? Treating cancer?" Gu Yun asked uncertainly, he couldn't understand. Professor Zhang had already expected it and said: "Look down!" Gu Yun looked down, and suddenly his eyes widened because the report said: "You can try to use low-concentration aqueous solutions to develop treatments for AIDS and other diseases." Drugs for diseases" Seeing Gu Yun's expression, Professor Zhang promptly explained: "AIDS should be treatable, but further trials are needed! As for cancer, although it can kill cancer cells, the concentration of the solution is too high and is harmful to health. The damage to cells is too great, unless a method can be found to remove this side effect! " "Yeah!" Gu Yun nodded. He was extremely surprised that it could cure AIDS. He didn't expect to be able to cure cancer. "Should this discovery be made public?" Professor Zhang asked a question that concerned him. Gu Yun hesitated, thought about it, and decided: "Let's announce it! However, the source of that crystal must be kept secret!" Considering such a big discovery, it would be no different if Professor Zhang is not allowed to announce it. Yu asked him to walk at night in brocade clothes. If that was the case, then his research on the antidote would not be active, and his view of Gu Yun would also turn negative. He didn't know that Gu Yun had so many secrets. "I know that!" Professor Zhang nodded, and then looked at Gu Yun, "If the research results are to be recognized by others, we need more crystals of that kind. Do you still have them on hand?" "I don't have much left. That kind of spider is very difficult to find. I encountered a few at a time because of luck!" Gu Yun reluctantly took out five magic cores and handed them to Professor Zhang, and then warned: "But Professor Zhang, the research on poisons can be done! Can't let it go!" "Of course, that aqueous solution can detoxify, I will allocate more power for further research!" Professor Zhang happily took the five magic cores and put them away carefully. "Okay, then I won't disturb you!" Gu Yun stood up, went to the private room, and walked out of the laboratory. Professor Zhang sent Gu Yun to the entrance of the laboratory before returning. After Gu Yun left, he picked up the phone and dialed a number. After the call was connected, Professor Zhang said: "Director Yin, I have a major discovery here that requires further research. Can you come over and have a look Okay Okay" Gu Yun returned home and received another call. A phone call. The call was from Lu Feifei. As the squad leader and a fellow villager, she was also very concerned about Gu Yun's final exam issues. Since Gu Yun would not drop out or suspend school for the time being, he promised that he would study hard, which made Lu Feifei put down her worries. Hanging up the phone, Gu Yun changed into the Confucian scholar's uniform, hugged Xiao Bai, activated the inverse astrolabe, and traveled through time again. This time, he went to the Shizhou World. There are three main purposes for coming here. The first is to get a feel for the situation and learn the language; the second is to continue practicing magic and fighting spirit; and the third is to read college books and prepare for the exam. Whether you drop out of school, take a leave of absence, or fail a course, it will look bad on your face! The place we passed through was a mess of graves, with hundreds of large and small graves. From time to time, there were crows chirping from all around, which sounded so gloomy and scary. ??Gu Yun walked out from behind a tall tombstone, looked around, and found a path out. Along the path, Gu Yun walked out. When he walked to a new grave, suddenly there was a movement in the grass not far from the grave. Gu Yun looked over and found nothing. Just as he was about to leave, Xiaobai in his arms suddenly roared and roared into the grass. Gu Yun stood up again, took out several passive defense magic items obtained in the magic plane and put them in his pockets. After ensuring his own safety, he picked up a few pebbles from the ground and threw them into the grass. , and then be on high alert. Rustling, something seemed to be moving in the grass, and it hit the grass, making a slight sound. "Come out! I won't be polite if you don't come out!" Gu Yun yelled, completely forgetting that this was a different world. Others couldn't understand his language, and the unknown objects in the grass were not necessarily people. But unexpectedly, when the unknown object in the grass heard Gu Yun's roar, he slowly opened the grass and walked out cautiously. "What came out of the grass was a child. His dark eyes were very smart. He looked less than 10 years old. He didn't know whether he was a boy or a girl. Gu Yun looked at this child and felt a pity. The child was skinny, dirty, his clothes were in tatters, his hair was messy, as if he hadn't been washed in several years, and there were many large and small scars on his hands, legs, and neck.
