Under One Person: I Can Change Jobs Infinitely.

"It's just that those plagues can't be cured..."

"Incurable? What do you mean?"

"Mother Wu said that the virus that caused the plague has become one with the patients and cannot be eradicated."

Yan Shuangying explained, "Even if the symptoms are suppressed using the secret medicine, the virus will continue to multiply after a period of time and will still cause a plague."

Huang Yu frowned: "So, these patients will have to take medication for life to suppress the virus, and even then, there's still a possibility of triggering a large-scale infection?"

"Yes."

Yan Shuangying nodded silently. When he first heard the news, he was also incredulous and felt extremely troubled.

What can we do? We can't just kill all the sick people, can we?

If we don't kill them, these patients will become a hidden danger, potentially triggering a new wave of infections at any time.

Therefore, Yan Shuangying could only take care of the patient first, and set aside a special area for isolation and treatment.

Basically, the plague in the city has been brought under control, leaving only these infected people, who are still unsure of what to do.

Yan Shuangying continued, "Mother Wu and Mr. Niu are already trying to find a way to cure it completely..."

Huang Yu hummed in response but did not reply, instead falling into thought.

He wondered, how did this happen? How did the virus become one with humans?

After much thought, Huang Yu came to only one answer: the plague virus used by the Japanese doctor was likely a retrovirus.

Damn it, those damn quack doctors!

Has technology become this advanced? They've created such a disgusting virus!

Now, Huang Yu has once again witnessed how troublesome the Death Doctor is, no wonder it has aroused public anger.

Retroviruses are viruses that can integrate their own genes into the DNA of a host cell.

Afterward, the integrated viral genes are passed on to daughter cells as the host cell divides, achieving long-term latency.

The infamous HIV virus is a type of retrovirus.

Even in the 21st century, there is no good treatment for this virus; the only option is long-term suppression.

"If medical methods don't work, then I'll try supernatural methods."

Huang Yu's eyes gleamed as he thought of the panacea the German magician had given him.

A super potion that combines medicine, alchemy, and spells.

The treatment involves using medication to strengthen the body's foundation and enhance the patient's own resistance, then using a purification array to weaken the toxicity of the virus, and finally using a purification spell to completely eliminate the virus.

Perhaps this method can truly cure patients completely.

However, Huang Yu has not yet changed his job to [Mage]. If he wants to refine potions efficiently, it would be best to complete the [Mage] job change quest first.

With the help of the [Mage] talent and special bonuses, learning purification spells and brewing potions will be easier.

Thinking of this, Huang Yu handed Yan Shuangying a list, which contained all the supplies needed for the All-Spirit Healing Elixir, as well as other items used for cultivation.

"Go and prepare these things first; I'll need them later."

"Furthermore, we must closely monitor the plague within Fucheng and absolutely prevent it from spreading!"

Yan Shuangying took the list and solemnly said, "Understood!"

……

In the spacious courtyard, Huang Yu silently examined the magic wand in his hand.

This is a magic wand left behind by a dark sorcerer from the Emerald Society.

It is about 30 centimeters long, with the staff made of blackthorn wood and the core being the horn of an alchemical monster called a basilisk, which has a great enhancement to black magic.

However, Huang Yu never felt comfortable using this wand, as its magic output efficiency was very low.

Even after using the [Hundred Refinements] talent to refine the Blackthorn Lee Wand, it wasn't very useful; it seems that wands don't fall under the category of weapon crafting...

In the Western magical tradition, the wand is an extremely important tool, which magicians use to channel their magic power, thereby concentrating the effect to achieve more complex purposes.

Of course, there are also spellcasting methods without a staff.

However, casting spells without a staff is very difficult and is an advanced skill that only a very few magicians can master.

"Heh, the wand chooses its master. It seems you've never really approved of me."

"Does it mean you think I'm not evil enough?"

Huang Yu's eyes flashed with blue light as he used the Eye of Truth to examine Blackthorn Lee's wand.

As expected, the vibrational strings of Blackthorn Lee's wand were not quite in harmony with him.

Each wand is unique, its properties depending on the plant from which the wood is derived and the creature from which the core is derived.

It can be considered a product of the fusion of alchemy and magic.

Previously, Huang Yu had observed from the perspectives of weapon crafting and mechanical arts, but he had never been able to grasp the essentials and replicate the techniques.

Now, from an alchemical perspective, it is quite obvious.

Huang Yu speculated that the earliest magicians did not have wands, but used some natural objects to help them cast spells, such as human bones, human blood, the bodies of monsters that had become spirits, and objects full of faith power.

As things gradually developed, alchemists invented wands for magicians, which led to a surge in magicians and made them a Western supernatural school that coexisted with alchemy.

"If a worker wants to do a good job, he must first sharpen his tools."

"Then, I'll make myself a suitable wand first."

Chapter 186 Professions: [Mage] [Dark Mage]

How can a powerful magician be without his own magic wand?

In Huang Yu's eyes, the making of magic wands was no secret. With a few more tries, he could make his own magic wand.

First, for the staff itself, you need to choose a suitable type of wood.

Just then, Yan Shuangying had already sent over various kinds of timber for Huang Yu to choose from.

"Peach wood is the best for warding off evil spirits, but unfortunately I specialize in black magic, and peach wood is too righteous and masculine."

"When I have time to learn other magic later, I can make a magic wand out of peach wood and play with it."

Huang Yu picked up the pieces of wood and examined them one by one.

The wood used to make a wand cannot be chosen arbitrarily; rather, it must be carefully selected based on the wood's inherent qualities, texture, and symbolic meaning.

“Pine and cypress trees, which are evergreen and symbolize righteousness, immortality and steadfastness, do not quite fit the bill.”

"The locust tree, the ghost among trees, is both a spirit tree and a ghost tree. This is not bad and can be considered as an alternative."

"Willow trees are planted during Qingming Festival and broken off as a farewell gift. They are also regarded as sacred trees and trees that frighten ghosts. This is not bad either."

"..."

After examining each piece, Huang Yu ultimately decided to try using locust wood.

If it's not suitable, you can choose another type of wood to make the wand.

After choosing the staff shaft, the next step is the staff core.

"Generally speaking, the core of the staff must be selected from biological tissues with extraordinary energy, such as demonic beasts and alchemical monsters, and must have a certain affinity with oneself."

"Hmph, what else could possess greater energy than my body, and be more compatible with me?"

Huang Yu looked at his body and a slight smile appeared on his lips.

With such powerful life cultivation and after long-term tempering through the three stages of reverse life, his physical body has already undergone a qualitative change.

Those so-called immortals who have cultivated for hundreds of years may not necessarily be as strong as him in terms of physical strength.

Therefore, his own body tissue is the most suitable and powerful core for the staff!

"Hair, beard, nerves, and bones are all suitable for making cane cores."

"But only the nerves of the heart can make the best wand."

At least in the memories of the dark sorcerer Will, many of the powerful wands that Huang Yu knew of were made from the hearts and nerves of monsters and demons.

"Tsk, it might hurt a little."

Huang Yu gritted his teeth, entered a state of reversal, reached into his chest with his right hand, dug out a beating heart, leaving an empty hole.

Subsequently, the reverse life force emerged, the heart recovered, and the cavity healed again.

With his reversal of aging cultivation, he could have already reshaped his three cores. He was only one step away from becoming a Primordial One and breaking through to the third level.

Rebuilding a heart is a piece of cake.

Huang Yu placed the beating heart on the table. The heart still emitted a faint, resilient white glow, demonstrating its vigorous vitality even after being removed from the human body.

It actually looks a little eerie.

After removing all the nerves from the heart, Huang Yu's heart transformed into a reverse-life essence and dissipated into the air with a thought.

It's best not to leave your own body parts in the world, lest they fall into the hands of evil people and be cursed.

"Alright, we can start making it now."

Looking at the materials in front of him, Huang Yu found that there was plenty of locust wood and more than twenty heart nerves, which was enough for him.

Following the crafting method of the Blackthorn Plum wand, Huang Yu made his own locust wood wand after about seven or eight attempts.

"Hmm, not bad, I feel much better right away."

Holding the locust wood magic wand, Huang Yu felt a sense of connection welling up inside him, as if the wand were an extension of himself.

That's true; not just anyone can use their own heart and nerves to create a wand...

Huang Yu chanted an incantation, stirred his emotions, and attempted to use the magic wand.

Dark magic stealth!

One minute later, darkness fell, and all the light around was drawn to the wand.

Within a radius of 300 meters, the area was plunged into eternal darkness, so dark that one could not see their own hand in front of their face.

Half a minute later, the darkness gradually dissipated, and light returned.
