Unfortunately, a week later, he himself contracted an infectious disease and was in a coma for three days without water.

It had been planned to return home the next day if Davis was not dead, but the next day no one expected that God stretched out his loving hand and touched Davis's head.

This guy's condition has actually improved, and it is even unbelievable that he can act on his own in the afternoon.

After ruling out all possibilities, a large group of experts set their sights on the plant called "Woo Ka Bang Zu".

A whole ton was immediately collected and shipped back to the United States, and after two weeks of hard work by Davis and the group of experts, it was finally discovered that the plant had a special enzyme that could stop the replication of the virus and break the chain of biochemical reactions within it.

The only drawback is that the protein content is destroyed by stomach acid, and it can only be effective when it enters the body from the outside.

Another week passed, and there was not a moment when Johnson Pharmaceutical's machines were not in full swing, when the death toll from the epidemic in Africa had reached an astronomical number, and everyone thought that Africa was finished, cursing Satan as a demon, and fearing that the plague would spread directly to the European continent.

Some people even proposed to use extraordinary measures to control the spread of the epidemic in Africa for the sake of human survival, that is, massacres and cremation, which is naturally strongly opposed by the majority of people.

After another week, Davis finally came back with effective drugs and vaccines, and the ingredients extracted from the ancestors of the Uka Gang quickly controlled the epidemic, and also made Johnson Company make a lot of money, and Davis has since become famous and written his own mark in the history of mankind's fight against infectious diseases.

"! It turned out to be the old man. Zhang Han suddenly slapped his thigh and stood up, startling everyone.

Fang Xinsheng asked, "What old man?" ”

Zhang Han said, "I am the director of St. Covia's Hospital, that is, the chief engineer of the Stanford Microbiology Laboratory, but I didn't expect to be Xi Zitian's mentor." ”

"You know him?"

Zhang Han nodded, "It's an acquaintance, I've met once before, and I did an experiment together, that old man is too verbose, and the noisy head is big, so he has to ask me to join his team." ”

Director Han snorted disdainfully, and the cool words came out of his mouth.

"Hmph, who is Professor Davis? The president of St. Covia's Hospital, a consortium invested in Davis's private hospital, is located in northern Maryland, which is considered to be the top medical institution in the United States, covering an area of 2.5 hectares, from prevention to rehabilitation supporting services are very complete, there are 3,000 beds alone, because the cure rate is as high as 80%, and there are as many as 200,000 patients from all over the world every year, often in a full capacity, I heard that it is still considering expanding the scale recently.

If you can be his student, you will definitely not worry about employment after graduation, and the salary of St. Covea is also an important reason why many people want to be a Davis student. ”

Zhang Han let out a long sigh, "Alas...... There is a lack of everything in this world, that is, there is no shortage of fools, what happened to Lao Tzu and Davis about your shit? I don't like to listen to it! No one is pushing you. ”

"You!" Where is Director Han blowing his beard and glaring at Zhang Han, there is no way to take Zhang Han, the surrounding group is watching at the same time, this person is really lost.

At this time, Zhang Han's mobile phone rang again, and when he picked it up, he saw that it was Li Zitian who came back.

"How about Xiaotian, did Davis agree?"

"No, I begged him for a long time, and Davis said that he has been very busy lately and has no time to go to China, but the leave for me has been approved."

"This bastard, when he has money, he actually forgot all about the obligation to save the dead and help the wounded." Zhang Han scolded, "You give him the phone, and I'll tell him." ”

After a few seconds, an old man's somewhat muffled voice came from the earpiece, a pure American English,

"I'm Davis, who are you?"

Zhang Han also speaks pure American English, almost to the point of being fake, and even the pronunciation mistakes made by Americans are imitated very well.

"Davis, how did you become a lackey of the rich man now?"

Everyone in the office was stunned, and they all knew that this guy must have been abroad for more than a day or two, and maybe he really knew Davis.

Davis was also stunned, stopped by this sentence, and then got angry,

"Who the hell are you, if it's just to say this, I can tell you that I'm too busy to have time to argue with you."

Zhang Han smiled and said in Chinese, "Old man Dai, do you remember?" ”

Suddenly, Davis's gaze froze, and his eyelids blinked quickly, "Han!" Is that you? Oh my God, is it really you? Unbuttoned the top two buttons of his coat, his face filled with disbelief.

Zhang Han said, "You finally remembered, I thought you had forgotten about me." ”

Davis slapped his forehead and smiled happily, "Huh...... You're the most talented student I've ever met, how could I forget you, I just forgot God's name, and I wouldn't. ”

"Davis, I find that you have changed, you have not understood the preciousness of life as much as before, and you are only obsessed with being a tool of production for the rich."

Davis hesitated,

"Han, to be honest, I also found that I have changed, the consortium bought out all the research and development results of the rest of my life, making me a complete machine, I am very distressed, but there is no way, the contract has been signed a long time ago."

Zhang Han smiled, "Davis, didn't you always want me to be your student?" ”

Hearing this, Davis's eyes lit up, and he smiled again, "Han! Have you changed your mind? I can assure Our Lady that with your talents, in time you will surely be able to surpass me in the field of bioengineering, no one can doubt that. ”

"Oh? Is it. Zhang Han got up from the sofa, obviously Davis, the old man, had already taken the bait,

"I'm still confident in my talent, but how do you prove that you're qualified to teach me?"

Davis was immediately upset, "What do you mean by that?" Isn't my accomplishment enough to be your mentor? I just received a notice from the Nobel Review Organization last week that the Nobel Prize in Medicine in October this year is already mine. ”

Zhang Han smiled strangely, and Davis was very unhappy.

Zhang Han replied, "Winning an award doesn't mean that you have this qualification, the person I admire must have hard power, come on, prove it to me." ”
