My health recovery is incredibly fast.

"Good day, Master." Xia Zuo bowed and greeted him.

Adanavardos wore a loose robe, his long, gray hair was tied back with a ribbon, and he wore no other decorations, looking very simple.

He had an old face with deep wrinkles, but his eyes were bright and his posture was straight. His voice was deep and resonant, which inspired trust in people.

Adanavados asked in a friendly tone:

"How are things? Are you able to adapt to life in the Silvermoon Federation?"

“I’m living quite well in the Silvermoon Federation. Thank you for your care many years ago. If it weren’t for you and the inspection team giving me that opportunity, I wouldn’t have my current status and position,” Xia Zuo said sincerely, bowing slightly.

“This is what you deserve, Shazo,” Adanavados laughed. “Come with me, I have prepared the elixir needed for the initiation spell.”

He gestured for Xia Zuo to follow him, and as they walked toward the elegant desk, he said:

"The combination of poison alchemy and biological materials science will drastically change its connotation, no longer focusing on the creation of poisons or antidotes."

Adanavados approached the table, reached out his hand towards it, and two inverted triangular potion bottles on the table slowly moved to Shazo's front.

He pointed to the white liquid on the far left and said:

"This is a secret elixir for creating a [spiritual medium] within your spiritual ocean. After drinking it, you must enter into deep meditation as soon as possible, and only awaken after the spiritual medium has fully formed."

He pointed to another vial, the liquid inside of which was two colors.

"This is an introductory elixir for imparting knowledge of alchemy. Before you drink it, shake it like this to fully mix the liquids together."

The medicine bottle tumbled several times in the air, and the two liquids merged into one, turning into a reddish-brown liquid.

"Similarly, after drinking it, you need to enter a deep meditation and wait for the effects of the medicine to wear off before you can wake up."

After Shazo put the two potion bottles into his alchemy pouch, Adanavados looked directly into Shazo's eyes and said in a low voice:

"As long as the mysteries of the brain remain unsolved, the soul will remain a mystery." (Note ①)

"The bloodshed and sins at the end of the Fourth Age made many alchemists realize that it was not advisable to study the soul by dissecting living beings."

"Since participating in the founding of the Temple, the alchemy school has explored a safe, stable research path that does not violate ethics and Temple laws."

"The status of poison alchemy has risen dramatically, becoming one of the core alchemical disciplines along this research path."

"This is because the fusion of poison alchemy and biological materials science has given birth to an alchemical product called [Aysu].

Adanavardos reached out and patted Shazo on the shoulder. "Judging from your performance in the assessment to become a master-level poison alchemist, I believe you will definitely make great achievements in the field of poison. I look forward to your performance."

“Yes, Master. I will do my utmost to study this field.” Xia Zuo didn’t know exactly what erox was… but that didn’t stop him from speaking frankly…

"If you successfully take the elixir, I will teach you how to use the new alchemical equipment in the alchemy room between 8 and 9 a.m. tomorrow. Now, go and prepare. Remember to take both doses of the elixir before nightfall, otherwise you will miss tomorrow's lesson."

"Yes, Master, I understand. Well then, I'll take my leave. Thank you for your guidance and advice." Xia Zuo bowed again, then walked briskly and steadily through the display case toward the office door.

...

in the hall.

Mars heard the sound of the stone door sliding and turned around to say:

"So? Got the secret medicine?"

Xia Zuo patted the alchemy pouch at his waist. "It's all here."

Mars beckoned and pulled the other person into the spiral staircase. "Then you must know about Ersin. I won't say much. You'll know what it is and what its uses are after you take the secret medicine."

The two walked uphill for a while and arrived at the dormitory floor located high up in the tower.

The teaching area of ​​the temple has a low population density, and each student has a single dormitory room with their own private bathroom.

Mars helped Xia Zuo tidy up the dormitory and stood in front of the door, saying:

"Well then, I'm off to class. My dorm is right next to yours. If you need anything, you can come find me before lunch break or bedtime. Also, remember to read the handbook on your bedside table. It has the code of conduct for the teaching area, which is roughly the same as the rules of Starry Night Castle."

“Okay, senior Mars. Thank you so much.”

Mars waved his hand, too lazy to be polite with him, and left, turning his back on him.

Xia Zuo closed the dormitory door and went to the window to look out. He suddenly noticed a piece of glass with extremely high transparency in front of him. If he hadn't tried to put his hand out the window, he wouldn't have been able to see the almost completely transparent glass...

He turned his gaze away from the window and used his detection spell on the white secret medicine on the desk.

...

After taking this secret medicine, a spiritual medium occupying 40 spiritual slots will be generated in the spiritual ocean.

The spiritual medium can be used to record alchemical knowledge at the expert level and above.

...

Xia Zuo brought up his character template.

...

[Mental] 14.36 (25.36)

【Spirit Gauge】22.5/56 (100)

...

There are currently 33.5 available Spirit slots.

You need at least 2 points of mental attribute value to meet the conditions for taking the medicine.

Xia Zuo had a sudden thought and clicked the plus sign next to "Spirit" twice.

After finishing his treatment, as usual, he first went to the washroom to take a good shower, changed into the robes for advanced students, then drank the usual potions such as the satiety potion, and finally drank the white secret medicine before lying down on the bed.

Approximately 3 hours later.

Xia Zuo awoke from deep meditation, and several lines of information from his cheat system appeared in his mind, reminding him that the mental medium had been successfully generated and the mental slot had been occupied.

Xia Zuo shook the second vial of the secret medicine to mix the two potions completely, then drank it all in one gulp.

This meditation session lasted quite a while.

When he woke up, the sky outside his window was filled with golden-red glow.

Xia Zuo did not get out of bed immediately.

He stared blankly at the bed curtains on the soft couch for a while, then sank into deep meditation again, carefully reading the alchemical knowledge on the spiritual medium.

Chapter 31 Bait

Here's the thing.

During Xia Zuo's study of poison alchemy.

Although textbooks or extracurricular books on poisons may not provide detailed explanations of units of measurement, a review of what has been learned easily leads to the following conclusion:

To date, Xia Zuo has used units of measurement ranging from centimeters to millimeters when researching or refining poisons.

Take, for example, the [Toxin Sense] skill, which can only be learned by expert-level poison alchemists.

When the toxin sensor is not activated, Xia Zuo observes the toxins with the naked eye.

At this moment, the higher his [Spirit] attribute value, the clearer the poisonous light he sees.

With at least 20 points in mental attribute, he can easily distinguish toxin clusters with a diameter of more than 3 millimeters.

After activating [Toxin Sensing], Xia Zuo can observe more subtle clusters of toxins at close range.

The prerequisite is that the elemental light emitted by these toxin clusters must have a diameter exceeding 1 millimeter within the field of vision.

If the diameter of the light emitted by a cluster of toxins is less than 1 millimeter, it is difficult to accurately observe its characteristics using a combination of the naked eye and toxin detection.

At the master level of poison alchemy, the scale was defined as follows:

On a macroscopic scale, the diameter of the corresponding toxin's rays is more than 1 millimeter.

At the mesoscopic scale, the corresponding diameter of the toxin's rays is between 0.01 mm and 1 mm.

On a macro scale, toxins are just toxins.

However, at the mesoscale, because the spatial length of a single toxin is too small, it basically has no toxic effect, so it is called erox.

Although mesoscopic yakine is not toxic, it still retains the diversity of toxins.

Sixty basic toxins can be combined to create thousands of complex toxins.

These compound toxins, after being refined, can generate many more compound toxins that have undergone one or more refinements.

According to alchemists, as many as 17 complex toxins have been discovered.

Correspondingly, there are more than 17 kinds of detoxifiers.

At the mesoscale, complex toxins are called left baits, and their antidotes are called right baits. There is a one-to-one correspondence between the left and right baits, and one left bait is matched with only one right bait.

Before Master Adanavardos handed the secret medicine to Shazo, he mentioned something:

"As long as the mysteries of the brain remain unsolved, the soul will remain a mystery."

He also mentioned that vivisection was not advisable when studying the brain, and the alchemists found a method that did not violate moral principles and temple decrees.

This method is:

[The Alchemist Brain]

Don't get me wrong, the alchemy school didn't want to create the human brain.

What the alchemists wanted to create was simply an alchemical brain that could receive, process, and react to external information, and then use it to study human consciousness and soul, instead of conducting experiments directly on living people as they had done at the end of the Fourth Age.

In the human body, the system most closely connected to the brain and second only to the brain in complexity is the nervous system.
