After ending the call, Gu Yun took out the textbook he hadn't read for a long time, changed into a Confucian robe, hugged Xiaobai, and was about to start the reverse astrolabe, when another mobile phone rang.

Could it be that Mr. Zhou is still not at ease? Gu Yun casually connected to his phone, "Hey? ”

"Gu Yun, why is your phone so difficult to call?" On the other end of the phone, Professor Zhang complained.

"Uh, Professor Zhang, I just came back from Africa and my phone is out of battery!" Gu Yun had to tell a small lie.

"Okay, Zhilu Dao!" Professor Zhang didn't delve into it, but asked, "Are you busy now?" ”

"Huh?" Gu Yun was strange for a while, but then reacted and said in surprise: "The antidote has been researched?" ”

"Ahem......" Professor Zhang coughed ashamedly, and said with some embarrassment: "Although the antidote has made some progress, it is not as good as the green crystal you gave me. It was the study of that green crystal that made a major discovery! ”

"Then I'll come right over!" Although Gu Yun regretted that the antidote had not been researched, he had made some progress. Moreover, the research of the green magic core has made a major discovery, and it is a major discovery from the mouth of an old qualification like Professor Zhang, which makes people excited to think about it!

"Okay, I'll be waiting for you in the lab!"

Gu Yun took off his Confucian clothes, went out with Xiaobai in his arms, and took a taxi to Professor Zhang's laboratory.

When he arrived at the place, Professor Zhang personally went out to greet him. As soon as he saw Gu Yun, he said excitedly: "This discovery may cause a sensation all over the world, where did you find that kind of crystal in Africa?" ”

"I found that by accident!" Gu Yun casually agreed, and then asked, "What about the research report?" ”

Seeing that Gu Yun was reluctant to say more, Professor Zhang didn't ask, and invited: "Let's go, go to the laboratory!" ”

Gu Yun followed Professor Zhang to a small office in the laboratory and sat down.

Professor Zhang took out a stack of more than 40 pages of reports and handed them to Gu Yun, saying, "All the research reports are here, a total of 46 pages, at least one major discovery!" ”

"At least one?" Gu Yun was taken aback and flipped through the report.

Professor Zhang pointed to the summary of one of the pages and said: "You can read this summary, you can't understand the specific data!" ”

"Oh!" Gu Yun followed Professor Zhang's guidance and saw specific and significant results.

"The crystals can be slowly dissolved in water, and 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 aqueous solution reaches 1.28%, it can kill a variety of viruses in the body of mice and excrete them without destroying infected cell tissues...... When the concentration of aqueous solution is less than 1.75%, it is harmless to mice; When the concentration of aqueous solution is higher than 2.47%, it will kill the cancer cells in the mice, but it will also cause harm to other healthy cells in the mice......"

"This is? Treating cancer? Gu Yun asked unconvincedly, he was a little confused.

Professor Zhang had expected it and said, "Look down! ”

Gu Yun looked down, and suddenly his eyes widened, because the report read: "You can try to develop a drug for the treatment of AIDS and other diseases with a low-concentration aqueous solution......

Seeing Gu Yun's expression, Professor Zhang explained in a timely manner: "AIDS should be treatable, but further tests are needed!" As for cancer, although it can kill cancer cells, the concentration of the solution is too high, and the damage to healthy cells is too great, unless a way can be found to remove this side effect! ”

"Hmm!" Gu Yun nodded, he was already extremely surprised that he could treat AIDS, he didn't expect to be able to treat cancer.

"Do you want to make this discovery public?" Professor Zhang asked a question that he was concerned about.

Gu Yun hesitated, thought about it, and decided: "Let's announce it!" However, the origin of that crystal must be kept secret! ”

Considering such a big discovery, if Professor Zhang is not allowed to make it public, it is tantamount to letting him walk at night. If that's the case, then his research on the antidote will not be positive, and his opinion of Gu Yun will also turn negative, he doesn't know that Gu Yun has so many secrets.

"I know this!" Professor Zhang nodded, then looked at Gu Yun again, "For the research results to be recognized by others, you still need more crystals of that kind, do you still have them in your hand?" ”

"I don't have a lot of hands left, that kind of spider is hard to find, I came across a few at a time, it's luck!" Gu Yun reluctantly took out five demon cores, handed them to Professor Zhang, and admonished: "However, Professor Zhang, the research of poisons can't be put down!" ”

"Of course, that aqueous solution can detoxify, and I will draw more strength to further study!" Professor Zhang happily took the five demon cores and carefully put them away.

"Okay, then I won't bother!" Gu Yun got up, went to the individual, and walked out of the laboratory.

Professor Zhang sent Gu Yun to the door of the laboratory before returning. As soon as Gu Yun left, he picked up the phone and dialed a number. After the phone was connected, Professor Zhang said, "Director Yin, I have a major discovery here that needs further research, can you come and have a look...... What a ...... Good ......"

When Gu Yun got home, he received another phone call.

The call came from Lu Feifei, who, as the class leader and fellow countryman, was also very concerned about Gu Yun's final exam.

Since Gu Yun would not drop out of school or suspend his studies for the time being, he promised that he would work hard to review, which made Lu Feifei let go of his worries.

Hanging up the phone, Gu Yun changed into a Confucian suit again, hugged Xiaobai, activated the reverse astrolabe, and crossed again.

This time, he went to the Ten Continents World Realm. The main purpose of coming here is threefold: one is to feel the situation and learn the language; the second is to continue to cultivate magic fighting qi; The third is to take a look at the university books and prepare for the exam. Whether it's dropping out, suspending school, or failing a course, it's too bad to look good on the face!

The crossing site is a mass grave, there are hundreds of large and small graves, and a few crows chirp from time to time around, which is very scary to listen to.

Gu Yun walked out from behind a tall tombstone, looked around, and found a path out of the road.

Along the path, Gu Yun walked out. As he approached the location of a new grave, suddenly, there was a movement in the grass not far from the grave.

Gu Yun looked over and didn't find anything. Just as he was about to leave, Xiaobai in his arms suddenly roared and roared at the grass.

Gu Yun regained his footing, took out several passive defensive magic items obtained from the magic plane and put them in his pocket, and after ensuring his safety, he picked up a few small pebbles from the ground, threw them into the grass, and then was on high alert.

There was a slight thud in the grass, as if something was moving in the grass, crashing into the grass.

"Come out! You're welcome if you don't come out again! Gu Yun roared, completely forgetting that this was a different world, his language was not understood by others at all, and the unknown objects in the grass were not necessarily people.

Unexpectedly, the unknown object in the grass heard Gu Yun's roar, but it slowly picked up the grass and walked out tremblingly.

Out of the grass came a child, his dark eyes were extremely smart, and he looked less than 10 years old, and he didn't know if it was a boy or a girl.

Gu Yun looked at the child and felt a burst of pity. The child was skinny, dirty, his clothes were tattered, his hair was messy as if he hadn't been washed for several years, and there were many large and small scars on his hands, legs, and neck.
