Under One Person: I Can Change Jobs Infinitely.

Huang Yu instantly understood Wu Ruilan and the others' concerns; it was indeed putting these elderly people in a difficult position.

However, there is a severe shortage of talent in this field in China, so we must allow these older generations to continue to shine for some time to come.

Huang Yu said confidently, "Everything you're worried about is not a problem!"

"In fact, this area is only just beginning to develop in the world, and everyone is just groping in the dark."

"In other words, as long as we take action, we are pioneers!"

Huang Yu's tone became impassioned, and he unconsciously used the [Fan Fever] talent.

"Don't you want to be pioneers in this industry?"

In an instant, Wu Ruilan, Mr. Niu, and the others became excited.

Tsk, judging from this, as long as they achieve even a little success, they'll be considered the patriarchs of this industry?

A grandmaster who can leave his mark on history?

He is a master-level figure who has made a name for himself in the world!

Wu Ruilan and the others were itching to get started.

If not for fame and high office, then for fame and high health... To be honest, behind every famous doctor, there is a heart that will be remembered for generations.

Otherwise, how could a barefoot doctor's manual have stirred up all the sects in the medical field?

While a doctor's compassion is one aspect, it also brings a greater sense of accomplishment—seeing one's work passed down and benefiting all beings.

Seeing that everyone was in the right mood, Huang Yu said, "Come on, I'll take you to another place so you'll have some idea of ​​what to expect."

With that, Huang Yu led everyone to another room.

This is a library, and there are also a dozen or so students from Xinghuo Academy organizing various materials in the archives...

Huang Yu explained, "These are all materials that I had collected. They include not only the most cutting-edge academic journals and scientific books from the West, but also some materials that I have compiled myself."

"Here, you can learn about the world's most cutting-edge research and build your own academic system."

“I will regularly have people send all the latest research findings published in the West here.”

It can be said that this library is the culmination of Huang Yu's current knowledge system, encompassing Eastern alchemy, Western alchemy, and modern technology—he has covered them all.

Huang Yu walked to the bookshelf, took out a textbook, and the cover read "Nature".

"This is a textbook I wrote in my early years. It has been iterated several times since then and is most suitable for science enlightenment. You can take a look at it first to get a basic understanding."

This book, *Nature*, was meticulously compiled by Huang Yu to teach his students at Xinghuo Academy, and I never imagined it would still be in use today.

Wu Ruilan and Mr. Niu exchanged a glance and said seriously, "Ayu, we are not people who are afraid of difficulties. We are not afraid to learn new things. On the contrary, we hope to have new things to learn."

"But we need time..."

Huang Yu laughed and said, "There's not that much time. I'll take you all to do the research directly."

"Learning while doing, and doing while learning, is the fastest way to make progress."

The reason Huang Yu was in such a hurry was that the sooner he could mass-produce penicillin, the greater its effect would be, the more people he could save, and the more wealth he could make.

At the same time, he also hopes to cultivate a group of talents in drug research and development as soon as possible.

Drug development is incredibly complex, requiring countless failed trials before a viable path can be found.

Huang Yu himself doesn't have that much time. Although he can use talents like [Eye of Truth] and [Gene Editing] to speed things up, he can't rely on them.

We still need to cultivate our own talent as soon as possible.

And medical masters like Wu Ruilan are the most suitable candidates!

They are already skilled in alchemy and understand the effects of drugs on the human body. They are also quite talented. They only need to change their mindset to become experts in drug development.

Huang Yu said, "I will use mechanical arts, alchemy, and weapon crafting to create a batch of qualified experimental instruments, and try to extract some samples during this period."

"After extracting the sample and verifying its efficacy, we will then plan for mass production."

"You guys finish up the barefoot doctor's manual thing first, then come to my place when you have time."

"I'll be spending most of my time in the lab during this period."

Wu Ruilan and the others nodded: "Okay, no problem!"

Mr. Niu patted Wang Zizhong on the shoulder: "Zizhong, you stay and help Mr. Huang. This will benefit you. Learn and observe more."

A hint of excitement appeared in Wang Zizhong's eyes: "Yes, Master!"

……

For a whole week, Huang Yu stayed in the laboratory, constantly researching how to extract penicillin.

Unfortunately, he wasn't an expert in pharmacology before, so he had to start from scratch in many areas.

In the laboratory, Huang Yu stacked more than fifty rectangular porcelain plates into an insulated box.

Each porcelain dish contains a culture medium with gene-edited Penicillium mold, which produces penicillin thousands of times more than ordinary Penicillium mold.

Tsk, in order to find a high-yield Penicillium mold, Huang Yu had everyone collect Penicillium molds growing in various environments, and finally found a suitable strain on a rotten cucumber.

Huang Yu then used gene editing to cut together multiple high-yield genes, and through continuous trial and error, he finally created this high-yield Penicillium mold.

The rectangular porcelain plate and the insulated box were also specially manufactured using alchemy and weapon-making techniques.

It has the functions of precise temperature control, maintaining sterile air, and corrosion resistance.

The reason is simple: penicillin is too delicate; it's sensitive to heat and alkali, and degrades easily if not handled carefully.

Penicillium is an aerobic bacterium, and it only grows vigorously on the surface.

Huang Yu, Wang Zizhong, and others began a series of extraction operations, constantly changing the pH value, and finally, after three days, they extracted a penicillin crystal the size of a fingernail...

Looking at the white crystalline powder in the glass bottle, Huang Yu sighed:

"It wasn't easy. We worked so hard for so long to get even a little bit of penicillin."

"But at least it was a success."

……

Chapter 168 [Warlord] Profession, God's Perspective

Wang Zizhong adjusted his glasses: "Mr. Huang, I'm here to conduct a live experiment."

Wang Zizhong took out eight white mice and injected each of them with a lethal dose of streptococcal suspension.

Four hours after they contracted the disease, four of them were injected with penicillin.

The results were obvious: the mice that were injected with penicillin all survived, while those that were not injected all died.

This result excited everyone in the lab.

Wang Zizhong's face was flushed: "Mr. Huang, we really succeeded! We found the miracle drug!"

Huang Yu laughed and said, "Everyone gets a bonus, let's celebrate tonight!"

Immediately, Huang Yu said seriously, "However, this matter must be kept strictly confidential. Not a single word must be revealed to the outside world. Everything must be arranged by the organization!"

Everyone readily agreed, "Understood!"

Huang Yu suppressed his excitement and fell into deep thought.

The penicillin sample was successfully extracted, but this is only a laboratory product, and there is still a long way to go before mass production.

Furthermore, the discovery of penicillin could be published ahead of time, but the degree of disclosure must be carefully controlled to prevent others from discovering the secrets of penicillin and making a fortune in silence.

However, Huang Yu wasn't too worried. Even if someone noticed the penicillin, they wouldn't be able to extract it in a short time.

At least for the next seven or eight years, there's no need to worry; it's not that easy.

Huang Yu was able to obtain laboratory results so quickly because of the help of the [Eye of Truth] and [Gene Editing] talents, as well as the alchemy and weapon crafting skills to create special equipment.

This point in time is the window of opportunity that Huang Yu uses to earn excess profits.

Ultimately, penicillin will become incredibly cheap; this is an inevitable consequence of technological development.

But it doesn't matter, Huang Yu has already gotten what he wanted.

"Huateng Group finally has its own pillar product, which can support its global expansion and make it a behemoth that influences the world."

"Hmph, I'm sure many people will come to snatch it."

"Let's do it then, it'll be just right to be a bit challenging."

"Going through some hardships can also help Jimmy and his gang of rascals develop some resilience."

Huang Yu's lips curled up slightly. With him backing him up, there was nothing to fear.

"Don't rush to publish the paper. First, we need to mass-produce penicillin, and then publish the discovery to maximize profits."

Huang Yu changed out of his lab uniform and was planning to go back to Fucheng for a visit.

Just then, a message appeared on the consciousness panel.

[They possessed an army of over a thousand men and occupied a city for more than a month.]

[The requirements for changing to the warlord profession have been met]

[Special profession obtained - Warlord (Tier 2)]

[Professional Talent Acquired:]

God's-eye view (You can view a real-time strategic panoramic map of all your controlled areas, with all your faction data automatically quantified and presented)

[Special bonus already obtained:]

1. Faster processing speed of government affairs

2. Military affairs processing speed has been accelerated.

Huang Yu suddenly realized that the one-month period had ended, the conditions for changing jobs had been met, and he had already changed jobs to the [Warlord] profession.

Huang Yu quickly glanced at the [God's Perspective] talent, and as he expected, it was indeed a Chongzhen simulator!

"Tsk tsk, being able to quantify various data of its subordinate forces in real time is insane."

"From now on, anyone who wants to deceive their superiors or cover up their mistakes will probably be unable to do so."

For the highest ruler of a country, the most feared thing is information distortion, that is, all the military and political data obtained are wrong.
