"Wow! We're rich!" After all the students left the classroom, Li Miaomiao couldn't hide her excitement.

Zheng Li: "Calm down, it's only 70,000 yuan, it's a small amount."

Li Miaomiao felt that Zheng Li was putting on an act: "Stop showing off, we can still be friends. You used to earn 100 yuan for half an hour, but now you've taken 70,000 yuan and you're still acting calm."

Zheng Li: "What I need money for are resources that money can buy, not a bunch of numbers."

Li Miaomiao snorted coldly: "You said 82% before, so I'll give you the 500 yuan change. I'll take 20% of the 70,000 yuan, which is 14,000 yuan."

"I thought it was just a sales job, but I ended up doing what the class teacher asked me to do too. Earning this 10,000 yuan wasn't as easy as I imagined."

Zheng Li: "Yes, you deserve this 14,000."

Li Miaomiao: "At least you have a conscience. If you work hard with this money, you won't have to worry about money throughout your university years or even until you graduate."

"If I specialize in preparing students for the postgraduate entrance exam in mathematics after graduation, I can easily earn four or five hundred thousand yuan a year."

"Jiangcheng may not have many other things, but it has a lot of college students."

"By the way, we can also expand our training to include Mathematics I and Mathematics II; you'll make a fortune from it."

As a student in the School of Economics and Management, he could talk endlessly about the commercial prospects.

Zheng Li replied, "I only have time to do this this year. I have more important things to do next year."

Li Miaomiao asked curiously, "What is it?"

She was actually happy with Zheng Li's decision, because if Zheng Li had really been obsessed with making money through tutoring, she would have looked down on him.

Making money is one thing, but one cannot live solely for money, especially since, in her view, Zheng Li possesses extraordinary talent in scientific research.

Zheng Li kept everyone in suspense, saying, "You'll know next year."

......

The first semester of freshman year passed in the blink of an eye, and the Mathematical Contest in Modeling (MCM) only lasted four days. Apart from the weekends when he was tutoring others, Zheng Li spent the rest of his time traveling between the laboratory, dormitory and library.

"I heard from my dad that you did some really outstanding results and are going to publish in Nature?"

After spending a semester together, Li Miaomiao had already revealed all about her family background to Zheng Li.

When Li Miaomiao first heard the news, even though she was very optimistic about Zheng Li, she still couldn't believe it, given how prestigious Nature is.

To put it simply, this level of publication is enough for Zheng Li to graduate with a PhD in three years, and after graduation, he can start as a professor at Jiangcheng University without having to do postdoctoral research.

Jiangcheng University published its first-ever Nature main journal paper only three years ago.

They are no match for the Young Thousand Talents Program or the Yangtze River Scholars Program.

"I only did a small part of the work," Zheng Li replied.

Li Miaomiao asked, "Be more specific!"

Zheng Li: "Artificially synthesized endorphins are endogenous (secreted by the pituitary gland) morphine-like biochemical synthetic hormones."

Li Miaomiao said helplessly, "Speak like a normal person, don't be like my dad, always saying things that others can't understand."

Zheng Li explained in detail: "Simply put, endorphins are peptides in the human body that have effects similar to morphine, which can make people feel happy and strengthen the immune system."

"Previously, humans could only extract such long-chain organic compounds containing a large number of amide bonds from mammals and could not synthesize them artificially."

"This compound is automatically secreted when you feel pain."

"My job is to find a way to artificially produce endorphins."

"If industrial production can be achieved in the future, it will be equivalent to morphine."

"However, morphine is highly addictive, while endorphins have not been produced on a large scale before, so it is impossible to determine whether their addictiveness is weaker than that of morphine."

"But its analgesic effect is definitely no weaker than morphine."

Zheng Li knew very well that endorphins were far more potent than morphine. Endorphins were not addictive like morphine, and their analgesic effect was much stronger.

More importantly, the combination of endorphins and enkephalins does not excite people; instead, it puts people into a sage mode, causing them to lose all desire for everything.

Li Miaomiao looked at Zheng Li with admiration: "Wow!"

"That sounds really impressive."

"Zheng Shen truly lives up to his name."

"By the way, did my dad mention changing your major to you?"

“He might not have pressured you before, but ever since you went to their lab, he’s been nagging you to change your major every day.”

“Previously, he might have waited until you graduated with your bachelor’s degree to let you transfer to the School of Biology.”

"Have you submitted your paper yet?"

Zheng Li nodded: "It's already been thrown out."

Li Miaomiao asked, "Can the experiment on artificial endorphins be reproduced?"

After nearly half a year on Earth, Zheng Li's human side has become increasingly apparent. Upon hearing this, he rolled his eyes helplessly and said:

"What are you thinking? If you can't reproduce it, you can forget about publishing in Cell's sub-journals."

"Of course it can be reproduced."

Li Miaomiao revealed an expression of realization: "At the fastest rate, from Nature's review to the reproduction of the experiment and then to publication, it takes at least three months."

"This is only if an academician makes an appointment. If it's to be published in three months, the entire School of Life Sciences will definitely want to transfer your student status to the School of Life Sciences before publication."

"Otherwise, when Nature publishes it, the headlines of major media outlets will be: 'The strongest math genius in history publishes a paper in Nature' during his freshman year.'"

"Where will the School of Biology look like then?"

"A first-year student from the Department of Mathematics published a Nature paper that no one from the Department of Biology had ever published before."
