I put you in charge of those rebellious female soldiers, how come they all became top special forces

Chen Zheng didn't give anyone time to react and continued speaking.

"In conclusion, I recommend switching to fractional extraction."

"First, use a low-polarity solvent to remove the interfering components, such as dichloromethane or n-hexane, and remove the fat-soluble impurities."

"Then, a phosphate buffer solution with a specific pH value is used for targeted extraction to separate the target alkaloids."

Unlike Xu Jiaming, who liked to use technical terms for every word, Chen Zheng tried to keep his word choice as concise as possible, even when facing two senior professors.

"It is recommended to control the pH range between 4.2 and 4.8 and the temperature not exceed 37 degrees Celsius to avoid the target molecule from undergoing a ring-opening reaction under alkaline conditions."

These figures didn't just come up on a whim.

These are the optimal parameters he deduced from existing data after his brain, which is comparable to a 9080ti, rapidly calculated with the help of his master-level potion skills.

Xu Jiaming's expression had already turned quite grim.

He swallowed hard and forced a rebuttal.

"This approach is theoretically feasible, but in practice, it is difficult to precisely control the buffer solution ratio. pH fluctuations can amplify the error in the extraction rate, making it difficult to reproduce under laboratory conditions."

The argument was fairly logical.

Chen Zheng glanced at him.

"0.136 mol/L potassium dihydrogen phosphate, 0.047 mol/L sodium hydroxide, and distilled water to a final volume of 500 ml."

"With this ratio, the pH can be kept stable at 4.46, with fluctuations not exceeding plus or minus 0.02."

The entire laboratory fell silent.

Shen Ling immediately picked up a pen and wrote down the string of numbers in her notebook.

After she finished writing it down, she bit the pen cap and mentally calculated it once.

The molar mass of potassium dihydrogen phosphate is 136, so 0.136 moles is...

She quickly started doing calculations on the paper with her pen.

Thirty seconds later, Shen Ling stopped.

She looked up, her expression turning one of utter shock.

The parameters provided by Chen Zheng were not only feasible, but also nearly twice as efficient as the theoretical extraction efficiency of their current solution.

What does this mean? It means that their team's workload for the next two weeks can be cut in half.

Shen Ling's lips parted slightly, and her gaze towards Chen Zheng became even more curious.

Who exactly is this person?

Zhou Jingtang stood in front of the whiteboard, motionless, and remained silent for a moment.

He slowly took off his reading glasses, took out a cleaning cloth from his pocket, and carefully wiped the lenses.

His students all know that this is a gesture he only makes when he is very serious.

After wiping his glasses, Zhou Jingtang put them back on and looked at Chen Zheng.

"Instructor Chen, which school did you graduate from?"

Chen Zheng shrugged: "Dropped out of high school."

Zhou Jingtang was stunned for a moment.

Fang Zhiyuan, who was standing next to him, was also taken aback.

The two old men exchanged a glance, and Zhou Jingtang suddenly smiled.

That smile contained surprise, appreciation, and a touch of indescribable emotion.

Fang Zhiyuan also showed a rare smile, put the marker in his hand on the whiteboard holder, crossed his arms, and looked Chen Zheng up and down.

Zhou Jingtang stepped forward and patted Chen Zheng firmly on the shoulder.

"The younger generation is truly remarkable. It's astonishing that a high school dropout could possess such research skills. I, an old man, have spent forty years in the lab, and it seems I've wasted my time."

Chen Zheng didn't reply, but simply nodded slightly.

Xu Jiaming stood there, his face flushing red and then turning pale.

His feelings at that moment were quite complicated.

There were very few spots available for this experiment, and I had been preparing for it carefully for a long time.

The other party did it with ease, and even did it better.

What does he want to say?

But when Zhou Jingtang's gaze swept over him, he shut his mouth completely.

His mentor's look clearly conveyed the meaning.

You've embarrassed yourself enough today, kid. Just shut up.

Shen Ling lowered her head, looking at the paper in her hand filled with numbers, and then couldn't help but look up at Chen Zheng.

Wearing a dark jacket and carrying a stainless steel thermos, he spoke slowly and deliberately, with little expression on his face.

This man was not really like the soldiers she knew.

The soldiers she had met included those who were burly and strong, and those who were reserved and rigid.

No soldier could point out the fatal flaw in the experimental design in just a few minutes while reading at a speed of one page every five seconds, and also give an extremely precise buffer solution ratio on the spot.

The keyboard was in the corner, the phone had been put away, and he looked very calm.

If the instructor doesn't even have this much skill, she'll eat her own keyboard on the spot.

Li Yue let out a long sigh of relief, and her clenched fist finally loosened.

Damn it.

An instructor is an instructor.

No matter where you are, no matter who you are or what their major is.

The instructor has always been the same instructor.

Zhou Jingtang waved his hand, indicating that we'd stop here for today.

"Formal research will begin tomorrow. I'll have everyone go over Xiao Chen's proposal tonight, and we'll discuss it tomorrow."

He glanced at the clock on the wall and added another sentence.

"Jiaming, tonight you input the parameters that Instructor Chen suggested into the model and run it once. I need to see the results tomorrow morning."

Xu Jiaming stiffened for a moment and lowered his head.

"...Yes, teacher."

The sound was much quieter than before.

Chen Zheng nodded, and without lingering, called Li Yue and Jianpan to prepare to leave.

As the three walked toward the door, they heard hurried footsteps behind them.

Shen Ling took two steps after him and stopped at the door.

She hesitated for a moment, then called out to Chen Zheng.

"Instructor Chen!"

Chen Zheng turned around.

Shen Ling scratched her head, holding the piece of paper filled with numbers in her hand.

"I didn't remember the last two digits of the parameters for that buffer solution... Could you please repeat them?"

Chen Zheng glanced at her and sighed: "Sodium hydroxide, 0.047 mol per liter."

Shen Ling quickly lowered her head to fill in the missing information on the paper, and after confirming it, she bowed earnestly once more.

"Thank you, Instructor Chen."

Chen Zheng hummed in agreement and turned to leave.

The three of them walked out of the laboratory and down the corridor.

As soon as they turned the corner, Li Yue leaned close to Chen Zheng's ear and said excitedly.

"Instructor, you're so handsome! That guy with glasses looked completely green!"

Chen Zheng rolled his eyes without turning his head.

The keyboard user quickly chimed in, "He's really handsome, but his style of handsomeness is different from everyone else's."

"Others are handsome because of their looks, their physique, and their talent."

"Our instructor is handsome... in every way!"

Li Yue thought for a moment, then nodded vigorously.

So far, they haven't discovered any areas where Chen Zheng is not good at.

Chen Zheng unscrewed the lid of the thermos and took a sip of goji berry water.

I can't be bothered with those two.

From the direction of the laboratory behind them, Zhou Jingtang's voice could be faintly heard.

"Jiaming, be more careful with your words in the future."

"It's true that everyone has their own area of ​​expertise, but you need to figure out what that person's area of ​​expertise is first."

Xu Jiaming did not answer.

Or rather, I couldn't answer that question.
