I'm a proper student; I only take nine kinds of potions every day.

The severity of the plague released by the copper plague depends on the type and concentration of the cluster virus in the body.

He can select a specific pathogen from that database according to different requirements, refine it, and then carry out single-point infection.

The symptoms exhibited by the target closely match the original clinical manifestations of that virus, but the effect is at least several levels more severe than under normal circumstances, and can far exceed the upper limit of effectiveness.

It is similar to an "ultimate enhanced version".

Concentrated syphilis: The body rapidly develops a large number of wart-like growths, extensive skin ulceration, and mental confusion.

Rabies: limb spasms, photophobia, hydrophobia, and aerophobia.

Plague: Black spots appear all over the body, lymph nodes swell rapidly, organs fail one after another, and high fever is accompanied by severe weakness.

……

The onset time of these symptoms depends on the target's own resistance and the dose of virus injected.

The shortest time to take effect is within the second his fingertips touch the other person's skin.

He has never encountered an opponent with a clear upper limit, but according to his own estimation, it should not exceed five minutes.

What concerned him even more was another one.

He discovered that once these viruses took hold, they seemed difficult to eradicate using conventional supernatural powers.

Because these viruses are not, in essence, supernatural forces.

They are just ordinary pathogens that have been induced by supernatural forces.

Once the induction is complete and the effects begin, ordinary supernatural treatments cannot erase them with a simple overlay.

Of course, this conclusion is only his current speculation, and it still needs to be verified in actual combat in the future.

Just as Ivan was conducting this series of tests, another prompt popped up on the panel in front of him.

[The Lion Potion's side effects have been reversed.]

Your physical flexibility has increased. Your constitution has been permanently increased by 0.05.

Your willpower has increased. Your spirit has permanently increased by 0.05.

"Expansion and willpower."

He silently repeated it to himself.

"It basically matches up."

"However, judging from these side effects, a Witcher can probably only take this Lion Potion about twenty times in his lifetime."

Twenty bottles of Lion Potion can add a bit of physical strength and a bit of spirit to him.

For an ordinary witcher, that means having to cut off a portion of their earnings for life.

How much physical strength can a witcher like Hill possess?

During their sparring session, she punched herself in the ribs, and the pain almost brought tears to her eyes.

In this situation, how much energy could she possibly have?

"My dear senior sister is a treasure."

Ivan clenched his fist.

"I was even thinking of learning a foreign language from my senior in the future."

He plopped down on the sofa, and a rare, almost solemn expression appeared on his usually playful young face.

"I can't watch my senior sister and senior brother ruin themselves little by little by taking magic potions."

Hill and Richard held a significance for Evan that no one else could replace.

The two people hadn't known him for very long.

These two people were the ones who gave him the most crucial and selfless help when he was penniless, facing crises and even life-threatening situations.

He already knew from Armitage that potions were ridiculously expensive to make.

If ordinary potions are like this, how much more so potions with extraordinary properties?

When his female assistant requested to use her extraordinary abilities to concoct potions, Richard simply agreed without asking any conditions.

Evan still vividly remembers Richard telling him with a smile that he often slept under bridges, and the smell of cheap Canadian whisky mixed with sweat and the sea still seems to linger in his nose.

"Senior brother, senior sister, don't worry."

He spoke silently to those two faces in his mind.

"With me here, you will definitely not follow the old path of your predecessors."

"I want to optimize the potion!"

Evan looked down at the faint mark on his wrist that had just been cut and scabbed over. His demon hunter vision seemed to see through his skin, which had been soaked in copper plague, and the poisonous blood flowing in his veins.

"Since I can have a fourth mark, other Witchers probably can too."

That ever-unconventional mind took flight once again, soaring freely into the sky.

"In that case, could I also do the opposite and optimize the Witcher's physical structure?"

"What if my senior brother had two hearts and three lungs when he transformed? Would he still be panting and sweating so violently after taking the Dragon Blood Elixir?"

"What if we implanted a pair of pebble kidneys in him to improve his detoxification efficiency?"

"Anyway, Witchers can assimilate the extraordinary characteristics of monsters into their own bodies."

"Then it doesn't seem impossible for me to modify the monster's internal organs and stuff them into my senior brothers and sisters' bodies, right?"

Thinking of this, Ivan's lips curled up, revealing a smile that was almost eager to try.

"It doesn't seem impossible for me, Yi Laoba, to take a small step forward and become Yi Banxian, does it?"

He chuckled to himself a few times, and suddenly felt a sense of anticipation for his future.

After his random thoughts subsided, he summoned his status panel and went through his attributes.

When Evan saw the long list of names, he couldn't help but sigh.

"This buff naming... panel, you're more abstract than me."

After confirming his body's attributes, Ivan changed back into his sharp, dark gray three-piece suit, took his felt hat from the coat rack, and went downstairs, closing the door behind him.

Stepping out of the apartment building's entrance, it was already four o'clock in the afternoon, and the sky was beginning to darken.

The gas lamps on top of the streetlights on Guding Street hadn't been lit yet. Behind the glass window of the bakery on the street corner, the proprietress was wearing an apron and displaying the few remaining loaves of black bread for half price.

Ivan turned two corners and headed north along the main street.

Soon, he arrived at the Bolton First National Bank, which stood at the street intersection.

This is one of the largest banks in the United States, and also one of the most prestigious names in Bolton City.

Depositing money in a place like this means you don't have to worry about your savings, along with the entire building, being wiped out by a group of robbers on a whim, ending up as just a few lines in the morning paper.

The bank's facade is in a neoclassical style, supported by granite columns, with a winged eagle carved in the center of the lintel, holding a bundle of arrows in its talons.

The two heavy oak doors were adorned with brass rivets, each one polished to a gleaming shine.

Ivan pressed one hand against the brim of his hat and pushed the door open forcefully with the other.

The door hinges creaked softly, followed by the distinctive, amplified sound of a large bank echoing through the lobby, amplified by the high dome of the ceiling.

In the spacious hall, small groups of people were talking quietly on the marble floor.

Some people were arguing in hushed tones, their spittle nearly splashing onto the shoulder of the elderly gentleman in a top hat across from them.

Some people sat on the bench with newspapers in their hands, glancing up at the counter in front of them every now and then.

In front of the long row of counters, several customers were queuing in a not-too-long line, waiting to conduct their business.

Above the counter hung a large clock in a dark brown wooden frame, its second hand ticking away.

The three armed security guards at the entrance watched the flow of people coming and going with vigilant expressions, the handles of the revolvers at their waists gleaming from their palms.

As soon as Evan pushed open the door, all three pairs of eyes swept over him.

But when they saw that the young man was wearing a well-tailored gray suit, his felt hat was neatly pulled down, and his leather shoes were polished so that they reflected a person's image, their gazes politely shifted elsewhere.

At the same time, a male receptionist wearing a light gray suit, with chestnut hair neatly parted in a three-seven split and a silver badge on his collar, greeted them with a smile.

"Sir, is there anything I can do for you?"

Ivan gave him a gentle smile.
