Under One Person: I Can Change Jobs Infinitely.

Shaking his head, Huang Yu directly summoned the three German Inhumans.

If you have any questions, it's best to ask the person directly; perhaps they have some secret they don't know.

"Haha! Mr. Huang, it's a pleasure to see you again!"

Paladin Lennie, the wise magician Moritz, and the navigator Daniel, led by staff members, filed into Huang Yu's laboratory.

Leni, leaning on his cane, extended his right hand and shook hands firmly with Huang Yu.

"Mr. Huang, did you invite us here today to discuss specific matters of cooperation?"

Huang Yu shook his head: "That's not urgent. I came to see you this time because of the All-Healing Elixir."

Moritz raised an eyebrow, walked over to the potion Huang Yu had just failed to brew, and couldn't help but ask:

"This is the panacea you concocted?!"

"Incredible! You've mastered the method of making the Panacea so quickly."

"No, you shouldn't have mastered it at all!"

Chapter 188 The Germans' Shock, The Reason for the Potion's Failure

Huang Yu laughed and said, "What do you mean I shouldn't have it? You gave me the potion formula so that I could make it, didn't you?"

Moritz wiped the cold sweat from his forehead, his Occlumency technique working frantically as he tried to clear his mind.

As a magician of the wisdom school, he is most skilled in mental spells, such as controlling his own emotions and thoughts, and analyzing the background of others.

But now, he was shocked to realize that he seemed to have never truly understood Huang Yu.

"God, just how terrifying is this Mr. Huang? Every time I think I've seen through his true nature, he always manages to come up with something even more unexpected."

"Could he not only be a powerful Eastern alchemist, but also an alchemist and a magician?"

"So young, so powerful, and he's even proficient in multiple disciplines?"

Moritz wore an incredulous expression, and the old gentleman Lennie and the scoundrel Daniel realized what was happening and were equally surprised.

To be honest, when Huang Yu flew over Fucheng a few days ago, his god-like and demonic figure really shocked them.

This is why the three of them were so respectful to Huang Yu—not because of any external forces, but entirely out of respect for a strong person.

Unexpectedly, Huang Yu has now given them another new scare.

Moritz said helplessly, "I transferred the Panacea to you in the first place simply to establish a good relationship with you and facilitate future cooperation."

“I didn’t expect that you could actually concoct the Panacea. In Europe, there are very few people who can concoct the Panacea.”

"And the fact that you can concoct the Panacea means that you know alchemy and magic!"

Lenny creased his brow and asked cautiously, "Mr. Huang, do you really know alchemy and magic?"

"Are you also a member of our Western supernatural world?"

Huang Yu nodded and said, "I have indeed studied alchemy and magic, and have a certain level of expertise in them."

"However, I cannot be considered a member of the Western supernatural world."

"Alchemy and magic are just my hobbies; alchemy is my profession."

Moritz said with a wry smile, "To have such a high level of expertise just because it's a hobby, and to be able to concoct a panacea so easily, how are we professional workers supposed to survive?"

Huang Yu laughed and said, "Who said I've concocted the All-Purpose Healing Elixir? To be honest, I only invited you here because I've failed too many times, so I wanted to see why I failed."

The three of them then stepped forward to examine the golden liquid that Huang Yu had refined.

Moritz muttered, "It looks similar to a normal panacea, but it seems to be missing something... It's definitely a failure."

Huang Yu said earnestly, "I followed the recipe you sent me exactly to refine the medicine. There were no problems with the formation and the casting of the magic spell, but I just failed..."

"Could there be some hidden tricks in the recipe you sent me?"

“Gentlemen, cooperation is easy to discuss, as it would benefit both of us. However, I am more interested in developing a potion to completely eradicate the plague of the Dead Doctor.”

"Please help me check where else I've made a mistake."

Moritz paused for a moment and said, "The potion formula must be correct. It was exactly the same when Master Taber gave it to me."

“Mr. Huang, how about this, you try to refine the potion again and see if you can find the problem.”

"Although I don't know how to brew potions, I once watched Master Taber brew the All-Healing Elixir, so perhaps I can learn some lessons from his experience."

Huang Yu nodded and said, "Okay, no problem."

After cleaning the table and preparing the equipment and herbs again, Huang Yu began refining once more.

The flames hissed softly, the potion gurgled, and Huang Yu's movements were smooth and elegant.

The faint glow of the transmutation array, the waving of the locust wood wand—everything was so harmonious.

The entire process of refining medicine looked so delightful.

Now, Moritz and the other two completely believed Huang Yu's words; this guy really did know alchemy and magic!

Their skill level is so high that it far surpasses that of us!

FUCK, you pervert!

Just when everyone thought Huang Yu was about to succeed, the potion boiled and fluctuated violently once again.

"Oh no! Run!"

Paladin Lennie's expression changed, and his body grew rapidly, his muscles bursting through his tuxedo, directly blocking the other two.

Huang Yu said helplessly, "Don't be nervous. Although we failed, I won't let it explode."

The next moment, the gray true energy surged in, and Huang Yu once again used his Yin-Yang balance ability to forcibly suppress the potion.

The three of them breathed a sigh of relief.

Huang Yu asked, "The three of you have all witnessed the process of refining the medicine. Can you tell me what the problem is?"

Moritz stepped forward and thought carefully, "It seems there's no problem. It's similar to the process I watched when Master Taber was making medicine."

"No, it could even be called perfect."

"But why did it fail?"

Moritz paced back and forth, then looked around and analyzed, "There's no problem with the technique or the materials, so it must be an environmental issue."

Huang Yu asked in confusion, "The environment?"

Moritz nodded and said, "That's right, the environment is also a necessary component for potions."

"It's normal that you don't know this because you haven't systematically studied magic."

"For example, some potions can only be made under moonlight, while others can only be made in a place bustling with people..."

Just like magic, some magic can only be used in specific environments.

Huang Yu suddenly realized that as a practitioner of Qimen Dunjia, he could understand the underlying principles very well.

The four elements of Heaven, Earth, Man, and God are: timing and location are extremely important factors that can greatly influence the success or failure of a spell.

It seems that many of the methods used in the world share the same underlying principles.

The drawing of talismans also requires choosing the right time and place to make it easier to draw successfully; this is also an example of how the environment affects magic.

Huang Yu asked, "So, I should find another place to refine the potions? What would be the most suitable place?"

Moritz said, "I'm not quite sure either. Tutor Taber was also refining it in his room, just like you."

"The only difference was probably the overall environment. At that time, the entire city was engulfed in the plague, and there were patients and dead people everywhere."

"Could this be the reason for the difference?"

"The potion must be brewed in an environment filled with patients..."

Huang Yu pondered, "I see. So the patient's emotions, groans, and pain are also considered ingredients for the potion?"

"Or is it death, or a virus permeating the air?"

"Never mind, let's give it a try first."

Huang Yu told the others to leave, intending to go directly to the quarantine area to refine medicine. If successful, it would prove their guess was correct.

Chapter 189 Treatment Plan, Successor of Ghost Needle

The quarantine area was located in a small village on the outskirts of Fucheng. Yan Shuangying replaced the villagers and relocated them to other places.

The patients were arranged to live in the village, and there are currently about 150 patients living there.

As you approach the village, the pungent smell of disinfectant hits you, and some staff members wearing masks and wrapped up tightly are spraying disinfectant.

This batch of disinfectant was transformed by Huang Yu using alchemy. China currently does not have a large-scale disinfectant industry; it is mostly imported.

But in such a short time, it was impossible to import disinfectant, so Huang Yu had no choice but to resort to some extraordinary methods.

Upon reaching the entrance, soldiers were stationed and patrolling, indicating that all preparations had been made.

Yan Shuangying came forward and said, "Master, this way please. The place for refining medicine and treating patients is in the center of the village. Aunt Wu and the others are there."

As he spoke, Yan Shuangying handed several masks to Huang Yu and the other three.

Huang Yu took the mask and said with satisfaction, "It's done quite well, very organized, and all the necessary epidemic prevention measures are in place."

Yan Shuangying laughed and said, "It's all thanks to your teaching, Master. Back in our nature class, you specifically taught us how to prevent plagues."

Lennie and the other two also put on masks and looked around curiously: "Mr. Huang, your measures are much more comprehensive than ours were back then, and your response was extremely fast."

"I thought you guys would drag it out for a few days."

Huang Yu shook his head and chuckled: "If we delay for a few more days, the plague will have already spread, and things won't be so easy then."

Led by Yan Shuangying, the group continued their journey.

Along the way, the groans of patients could be heard from time to time, and doctors and caregivers went back and forth, doing their best to take care of the patients.

To Huang Yu's satisfaction, although the patient looked weak, he showed no fear or signs of being tortured. It was clear that the conditions in the isolation ward were relatively stable and that he had not been mistreated.

Soon, the group arrived at the center of the village, where there were significantly more people. They were mostly highly skilled doctors from Fucheng, disciples from Xinghuo Academy who were interested in medicine, and some invited medical experts.

Led by Mrs. Wu and Mr. Niu, they were having a heated discussion about the treatment plan for the illness.
