My health recovery is incredibly fast.

After hearing the student's words, Beatrice rested her right elbow on the armrest of her chair, lowered her head, and gently stroked her chin. "What is your reasoning for deducing elemental toxins?"

Xia Zuo thought for a moment and said:

"In my view, elemental toxins have a distinct characteristic: their toxicity can be contained within the elemental ocean."

"So, I have a bold idea."

"Perhaps in a deep meditative state, we can look for which basic toxins can be contained in the ocean of the mind... They may be the raw materials of elemental toxins."

Xia Zuo looked at his mentor, who was frowning and silent, and added, "Uh... I haven't tried it, and I don't know if it's feasible."

Beatrice looked up, strands of hair slipping down her fair neck. "Your line of thinking is correct."

"My thinking was correct?!" Xia Zuo's eyes widened in surprise. This wildly imaginative line of thought was actually right.

“Hmm.” Beatrice paused, gazed at her student, and said:

Let me put it this way.

"To encompass the toxic effects of all 60 basic toxins within the ocean of the mind, and then to deduce the toxic effects of compound toxins within that ocean of the mind, is what expert-level toxicology alchemists do every day."

"Professor Kulov often meditates, studying poisons in the ocean of his mind. Of course, he studies highly toxic elemental crystals more often."

"Hiss..." Xia Zuo gasped, never expecting that his wild thoughts would actually be connected to an expert-level poison alchemist.

No wonder Professor Kulov was always meditating and I never saw him fiddling with poison bottles to develop poisons; he was conducting experiments in his mental ocean.

It seems that the discipline of poison alchemy allows students with exceptional alchemical potential who have independently conceived of elemental properties to practice meditation in advance, in preparation for the expert-level curriculum.

Beatrice took a locked metal box from the drawer.

She picked up a glass bottle about the size of a finger. "Do you remember this medicine?"

“I remember, Professor Kulov once gave me some,” Shazo said, glancing at the thin red thread in the bottle, his heart racing slightly.

"After you pass the test to advance to the expert level, you must drink ten doses of this potion."

"Ten?!"

How much experience and vitality attribute value would that require?

Even with his deepest cunning, Xia Zuo could no longer remain calm at this moment.

He quickly regained his senses and exclaimed in astonishment:

"Professor, I heard Professor Kulov mention that this potion is more expensive than shops on two streets..."

Beatrice put the potion back into the metal box and said:

"Compared to an expert-level poison alchemist, these expenses are nothing. The old bones of poison alchemy are still quite generous in this regard."

She put the metal box down and looked at the still somewhat shocked students. "Let's get back to the main topic. Do you have a plan for developing a new poison?"

"Yes, Professor, look."

Xia Zuo calmed his turmoil, took out his notebook from his bag, flipped to a page, placed it on his desk, and showed it to his tutor a line:

[A long-lasting poison that has a chance to prevent the caster from entering a shallow meditative state.]

Below this sentence are dozens of lines of text that record the idea and original intention of this plan.

Beatrice glanced at the contents of the page, then smiled and teased:

"You've only been a mage apprentice for a short time, and you're already thinking about harming yourself?"

Xia Zuo scratched his head sheepishly.

The research plan for this new poison was finalized after careful consideration.

The description of the [Spellcasting Instinct] trait clearly states that spells can be cast without entering a shallow meditative state.

Therefore, the new poison actually has no effect on him. It's like getting a free poison effect without any side effects while gaining experience.

Xia Zuo had also considered other toxic effects with longer durations.

However, they will more or less have a negative impact on physical appearance and daily work.

For example, there is a toxic effect called hemoptysis.

During the duration of this toxic effect, the poisoned person will cough incessantly, and each cough will aggravate the wound deep in the throat, with blood flowing out along with the spit.

In conclusion, after careful consideration, Xia Zuo finalized the current plan and also explored some feasible paths.

Beatrice carefully read the words on the page, nodded slightly, closed the notebook, and handed it back to the student across the desk.

“Good idea. It will work. Try it out. From now on, you can study the formula for the new poison during the day and come to me to train your magic at night.”

"Yes, Professor."

Xia Zuo discussed the alternative plans with his mentor, and then went to the Great Alchemy Chamber to study poisons.

...

The expert-level promotion test requires the use of at least six basic toxins.

Following the established research direction, Xia Zuo began refining the publication and gradually noticed a detail he had never paid attention to before.

The poisons I refined before were all mentioned in the textbooks, with clear formulas and refining methods.

He had always believed that a certain toxic effect would only occur with specific poisons.

After numerous attempts at concocting poisons, Xia Zuo was astonished to discover that more than one compound toxin contained the toxic effects he needed.

Often, a complex toxin contains several toxic effects, one of which happens to be suitable.

This should be the most difficult part of this test.

The more basic toxins are used, the more types of toxic effects the toxins will have, and correspondingly, the more useless toxic effects will also increase.

The number of toxic effects of the product must be controlled, ideally to be only two.

How can six basic toxins combined only have two toxic effects?

Xia Zuo immediately thought of the antidote and realized what was going on.

If we label the six basic toxins with numbers 1, 2, 3, 4, 5, and 6.

让1号和2号产生的毒效，与3号和4号产生的毒效发生反应，只产生出1个新的毒效。

At the same time, ensure that the toxic effects produced by No. 5 and No. 6 are only 1.

In this case, the final toxic effects of the resulting product will only be two types!

Another approach is also acceptable.

1、2、3三种毒素产生反应，只生成1个毒效。其余三种毒素也是如此。两组相加后，毒效数量也可以控制在2个。

The promotion test for expert level requires the flexible application of knowledge at the proficient level.

Xia Zuo was certain that he had found the right approach.

He devoted himself entirely to researching new formulas, and his only leisure activity each day was having meals, taking walks, and chatting with Anru.

Even the practice of using poison to gain experience was temporarily put aside, with only nightly spell training remaining. There was simply no time to concoct Black Eye Poison anymore.

More than a month later, in the morning.

Inside the Great Alchemy Chamber.

Five vials of purple-glowing poison appeared on the table.

After cleaning the alchemy table, Xia Zuo sat down at the table and used his detection spell on the glass bottle.

..

[Item Name] Interference Agent

[Item Type] Poison

[Item Grade] Proficient Level

[Item Quality] Completion rate 100%, Perfect

[Associated Resistance] Four-system resistance

It is expected that once all four resistances reach 6%, the effect of this item on the host will be significantly reduced.

[Item Description] The developer and maker is Xia Zuo.

[Item Effects]

After ingesting this poison, you will gain 3 stacks of interference effect and 3 stacks of silly pleasure effect, both of which last for 3 hours (2.85 hours).

For each layer of interference effect, there is a 15% (13.35%) chance of failure each time you enter a shallow meditation state.

For each stack of the "Silly Laughter" effect, there is a 15% (13.35%) chance of emitting a silly laugh every 10 minutes.

(The results in parentheses are the calculation results affected by willpower and resistance.)

Chapter 13 The Meditation Alchemy Table

Interference agent, interference effect, silly fun effect—these are names Xia Zuo came up with himself.

Throughout the development of the new poison, he used his experience in poison making and his understanding of basic toxins to gradually deduce feasible solutions.

In addition, his poison-making skills are now superb, so his cheat abilities rarely appear.

The only place where the Detection spell is used is for finishing operations.

Xia Zuo needed to make sure this step went smoothly to avoid wasting time refining it.

He took a vial of poison into the shower room, changed into a clean robe, and headed toward his mentor's study.

A short while later, Xia Zuo returned with his mentor's instructions.

After examining the poison developed by the students, Beatrice had them remove the "Silly" effect.

This was within Xia Zuo's expectations.

For the past month or so, he has been developing the toxic agent while also figuring out how to remove the toxin. Now he has a complete plan for refining the base liquid.

Inside the Great Alchemy Chamber, Xia Zuo once again enthusiastically fiddled with the alchemy table.

The toxicity needs to be removed by letting it stand for 30 days.
