Xiao Rong is Kong Hanshan's eldest daughter, and has been living abroad, since Kong Hanshan fell ill, he often regarded Tan Xiran as his daughter, and Tan Xiran has long been used to this.

Now seeing Kong Hanshan's appearance, Tan Xiran knows that Kong Hanshan is sick again.

"What elixir?"

Tan Xiran asked Chen Wangrong puzzled.

Kong Hanshan was reluctant to undergo examinations and treatment when he first contracted this disease, but he has been receiving treatment from a private doctor since the last month.

If you want to talk about Kong Hanshan's medicine, it is in the drawer of his office.

But what the hell is the elixir that Chen Wangrong said, is it the bottle of things he left in the office that day?

"Oh, what you left behind last time was casually thrown away by Professor Kong."

Chen Wangrong was speechless for a while, but he seemed to find a trace of something strange in Tan Xiran's eyes, so he looked directly at Tan Xiran and asked, "And then you picked it up again, didn't you?" ”

Tan Xiran didn't expect Chen Wangrong to say this, she glanced at Chen Wangrong in surprise, and avoided her eyes unnaturally.

"I, I'm just a little curious, so I picked it up and asked one of my classmates who did drug testing to help test it."

Tan Xiran didn't hide it anymore, when she got off work to sort out her things, she happened to see the small bottle that was thrown aside by Professor Kong, and she picked it up and brought it home.

"Oh, what's the result?"

Chen Wangrong asked with interest.

At this time, Kong Hanshan was still clamoring to go to class, and the two could only chat while following him out of the library.

Tan Xiran said lightly: "The test did not find any harmful ingredients to the body, but it was just some ordinary refreshing drugs and some trace elements, which should be useless." ”

Of course, she didn't expect a person like Chen Wangrong to become smart after half a lifetime, a person who had not learned anything, to be able to make any great pills.

It's not a god like the Living Buddha Jigong.

She had been thinking so for a long time.

It wasn't until the husky she raised at home carried her back and dug out the remaining samples from the trash can and ate them that she felt that her perception had been completely turned upside down.

Chen Wangrong saw that Tan Xiran had already been tested, so he continued to ask, "Since there is no harm to the body, why don't you let Professor Kong try it?" ”

Tan Xiran thought for a moment before saying to Chen Wangrong: "After all, that thing is not made by a qualified manufacturer, if there is any problem after Professor Kong eats it, I can't afford to take this responsibility." ”

After Tan Xiran finished saying this, he added: "At least wait until the end of the animal experiment stage before applying for human experiments, even if you want to conduct human experiments, you can't use Professor Kong to do experiments, after all, he is old, in case there are any side effects......"

"You've already experimented on animals?"

Chen Wangrong interrupted Tan Xiran's words.

Because judging by her somewhat detached, respectful and curious attitude towards herself today, she must have discovered something.

Tan Xiran looked stunned, thinking that Erha, who was not doing anything in her family, had become smart and cold after eating garbage that day, not only could she understand her own words, but also learned to go out to buy things by herself, she finally said with some hesitation: "Sort of." ”

She later took a few more pills for the husky at home, and has been keeping track of the changes since taking the pills.

It was also because of this incident that she became curious about Chen Wangrong.

So when she heard Kong Hanshan mention Chen Wangrong again, she suggested that he come to talk to Chen Wangrong.

Chen Wangrong looked at Tan Xiran and said very firmly: "Believe me, there will be absolutely no side effects." ”

At this time, the three of them had already arrived at the central garden of the school, and under the scorching sun, Kong Hanshan suddenly stopped and looked around.

"Professor Kong, why don't you leave?"

"Where are we going?"

Kong Hanshan asked very confusedly.

"You said you were going to class, so we're going back to the lab to get ready."

Tan Xiran said in a gentle voice, not at all like he was facing his teacher, but like he was talking to his students.

Kong Hanshan turned his head to look at Chen Wangrong again, and suddenly said to Chen Wangrong very seriously: "Xiao Chen, I am very pleased that you can stay in school and learn something, I shouldn't have lost my temper with you like that day, the equipment in our laboratory is indeed backward, but there is no way, the school's funds are limited, and it can't be spent on my project alone." ”

Chen Wangrong glanced at Tan Xiran, and the two looked at each other.

So Professor Kong, this is, okay again?

Tan Xiran was obviously much calmer than Chen Wangrong, Chen Wangrong saw Kong Hanshan talking about the equipment, so he simply continued his words and said: "At present, the most advanced equipment is developed by a laboratory in Italy, and the movement trajectory of brain molecules can be analyzed through image tracking technology. ”

Kong Hanshan glanced at Chen Wangrong in surprise, and said with relief: "Young man, I didn't expect you to even pay attention to this kind of news in the academic world, yes, yes, it's a pity that you are not my student." ”

Speaking of this, Kong Hanshan sighed, thinking that Chen Wangrong's experience in the first half of his life was really a big delay for him, and he couldn't help but feel a little sorry in his heart.

"I also accidentally saw it while watching the news."

Chen Wangrong said perfunctorily.

Of course, he would not say that he knew this before he was born again, and that he had already experienced many things in the future that had not yet happened before he was born again.

The three of them continued to walk in the direction of the laboratory, and after being silent for a while, Kong Hanshan suddenly said to Chen Wangrong very seriously: "Actually, I want to apologize to you today, I know my own physical condition very well, I have been reluctant to admit it before, and now I have made up my mind to give up scientific research and go home to retire, let you young people do the exploration of science, I can't do it with my old bones." ”

Hearing Kong Hanshan say this, Tan Xiran and Chen Wangrong's faces changed.

When the three of them walked to the door of the laboratory, they happened to meet a thin and white boy wearing a pair of gold-rimmed glasses.

"Professor Kong, Senior Sister Tan."

He greeted the two, but his face changed slightly when he looked at Chen Wangrong, and he even glanced at Chen Wangrong and Tan Xiran with some defensiveness.

"Zhang Sheng, is there anyone else in the office?"

Zhang Sheng is one of the graduate students under Kong Hanshan's belt, and the graduate students under him often come to his office in shifts, doing just some cleaning and sorting out materials.

"Nope."

Zhang Sheng replied, and his eyes were again on Chen Wangrong's face.
