My health recovery is incredibly fast.

The twice-refined Black Eye Poison now has an additional illusion effect that allows users to see flesh buds.

This hallucinatory effect is the toxic effect that needs to be removed.

The poison effect that needs to be retained is the hallucination effect.

The first-refined Black Eye Poison has no hallucinogenic effects, but it does have visual hallucination effects, making it the best raw material for the base liquid.

The principle behind stripping the poison's effects is to transfer the hallucinatory effects of the twice-refined Black Eye Poison to the once-refined Black Eye Poison in the base liquid.

This part of the knowledge may seem complicated, but it is actually very easy to operate.

Xia Zuo spent the whole morning refining the required base liquid.

Then, take a bottle of twice-refined Black Eye Poison and pour it into the glass bottle containing the base liquid.

After sealing the bottle, simply let the mixture stand for 30 days, then open the stopper and check the color of the liquid inside to determine if the separation was successful.

If, after 30 days, the liquid in the bottle separates into two layers of different colors, like oil and water.

Then the separation was successful.

Afterwards, simply extract the upper layer of liquid and store the lower layer of liquid separately.

The results of the stripping process will take 30 days to be available.

Poison alchemists must meticulously record the entire alchemy process so that they can use the results to judge whether their alchemy operations were flawed.

So, after completing this operation, Xia Zuo sat down at the alchemy table and spent half an hour writing.

This was just to appease the professor.

With the help of his detection technique, he already knew that the result would be of perfect quality when he mixed the poison and the base liquid.

At noon, Xia Zuo and An Ru'er had lunch together, and then returned to their respective dormitories to rest.

...

1 pm.

He arrived at his mentor's study on time.

Beatrice sat behind her desk, closed the book in her hand, looked up at the door, and asked:

"You've arrived. How's the training for those four types of offensive spells going?"

"Good afternoon, Professor. I've almost mastered the first three forms, but I still need to practice the boomerang form a bit more," Xia Zuo said, standing with his hands at his sides in front of his mentor.

"Yes. Follow me. Today we'll learn fire spells with the [Burning] trait." Beatrice stood up and led her students deeper into the study.

A spacious magic training room.

At the other end of the training field, wind spikes, wind belts, and boomerangs made of silver sand were still tirelessly demonstrating the spell process.

Beatrice raised her right hand toward them, and the wind spikes and silver sands of the wind drifted back to her, leaving silver sand boomerangs floating back and forth not far away.

She stood on the open space of the training field, facing the students, and said:

"Fire spells also have several common appearances. For example, flames, fireballs, and fireballs. I think you have experience in the circus, so you should be familiar with these forms, right?"

After seeing the student nod, Beatrice continued:

"However, I regret to inform you that, at the mage apprentice stage, truly achieving the ability to spew flames out of thin air is an extremely difficult thing."

"To spew flames out of thin air is a composite spell involving both earth and fire elements. You must first possess an elemental trait that can generate flammable materials, such as the [Shaping] trait you envision."

"Use this trait to cast a spell that generates flammable materials, and then use fire spells to ignite the flammable materials."

Even casting spells must follow the basic laws of nature… Xia Zuo frowned slightly, seemingly lost in thought.

Beatrice took a small, round leather pouch from her pocket, handed it to her student, and said:

"This bladder contains a flammable gas. Its nozzle has been specially modified."

"With enough skill, you can press the valve switch with your left hand to expel the gas from the bag, and at the same time use wind magic to control the expelled gas, making it drift towards your target."

"Once the flammable gas reaches the designated location, use the magic-level fire spell [Spark] on it. The instantaneous spark will be enough to ignite the flammable gas."

While listening to his mentor's teachings, Xia Zuo curiously picked up the skin bag and examined it repeatedly.

The valve on this bladder is made of thin, coiled metal tubes. There's a small valve where the brass-colored tubes connect to the bladder opening; this is likely the switch that controls the gas flow inside.

If you use it with a burning torch, wouldn't it become a flamethrower?

As Xia Zuo described his envisioned flamethrower design to his mentor, he gestured with his hand to show the approximate shape of the airbag.

“Yes, that’s right. There is such a thing.” Beatrice nodded slightly. “The flamethrower you mentioned is a product of weapons alchemy. This alchemical discipline is not allowed to appear at Starry Night Academy.”

Huh? Weapon alchemy researches flamethrowers?

Rexor's title in the Witcher school: Master of Weapons and Signs.

Xia Zuo suddenly realized... he might have some misunderstandings about the weapons of this world...

Beatrice snapped her fingers, drawing the students' attention and steer the conversation back to the lesson:

"Before we begin our formal lessons, you need to try to harness the energy of the [Burning] fire element. When you use the [Poison Crystal] meditation to contain this small element and cast spells with it, you will be affected by the elemental toxins."

"With your willpower, this interference is nothing and won't interrupt your spellcasting. However, the toxicity of the elemental toxins will be slightly enhanced during the spellcasting. You need to be more careful. Once your soul feels sore, you must stop casting the spell immediately."

"Yes, Professor."

Beatrice pointed to the air in front of the students, then crossed her arms and said:

"The method of casting Spark is similar to the spell I learned yesterday."

"While visualizing the patterns of the [Burning] quality, also visualize the appearance of sparks. Once you've finished visualizing both, simply repeat 'Burning' silently."

Xia Zuo straightened up, adjusted his center of gravity, and squinted his eyes to enter a shallow meditative state.

A few seconds later, he raised his right hand, palm facing forward, and silently said, "Burn."

"Snapped."

A brief, extremely bright yellow light flashed through the air, followed by a very faint sound.

Xia Zuo touched his forehead. "Professor, this should be a success, right?"

"Yes, it worked." Beatrice drew a circle next to her head with her right index finger and asked with concern:

"Are you feeling unwell anywhere? Like dizziness, swelling in your temples, or something like that?"

Xia Zuo pressed his hands around his head, while simultaneously reviewing the long message sent by the cheat system:

"The host has successfully cast a spell using the elemental poison crystal. The [Identity 1] entry has been updated, and the [Identity Bonus] has changed."

..

[Identity 1]: Mage Apprentice

【Identity Bonus 1】: 【Classic Text Combination】

【Identity Bonus 2】:

[Spell Training]

1. When you successfully cast a spell using the Obedient Element, you will receive an additional 10% to 50% experience bonus, as well as a small amount of Spirit and a small amount of Perception attribute bonus, depending on the spell's power.

2. (New) When successfully casting a spell using an elemental poison crystal, in addition to the above rewards, you will receive a small amount of Willpower and four elemental resistances.

..

"Successfully casting a complete Spark spell grants 2 power, 0.22 experience points, a small amount of Spirit and Willpower attribute points, a small amount of Perception attribute points, and a small amount of resistance to the four elements."

"Initiating data-driven modifications to Spark spell and generating a spell template... Modification complete, spell template successfully generated."

..

[Spell Name] Spark

[Spell Type] Attack

[Spell Grade] Trick

[Related Trait] Fire: Combustion

[Spell Power] Current maximum power: 2 points

(This spell is associated with the [Burning] trait. The [Burning] trait, when combined with the Diligent Element, provides double the spell power.)

[Spell Description]

When this spell is cast using an Elemental Poison Crystal, the effect of [Mild Poisoning Effect #1] will be increased by 2% (spell power * 1%) for the duration of the spell.

[Spell Effect]

When this spell is used, a small cluster of sparks will be generated at the designated location. The area affected by the sparks is a sphere with a diameter of 2 centimeters.

..

Beatrice and Kulov both mentioned that the effects of elemental toxins are somewhat enhanced when casting spells.

After digitizing the Spark Technique, the Golden Finger calculated a specific formula.

This casting cost is negligible compared to the effect of preventing elemental dissipation. What's more, you also get Willpower and four elemental resistance bonuses.

Thinking of this, Xia Zuo had a sudden thought and said:

"Professor, I don't see any discomfort in using elemental poison crystals to cast spells."

"I have a question. Among the elemental traits I've envisioned, which ones are relatively rare and suitable for the [Poisonous Crystal] meditation method to contain?"

"This is the course content of the Elemental Pattern Language. It will be taught to you after you have learned the common tricks."

Beatrice gently stroked her chin, pondered for a few seconds, and then said:

"However, since you've brought it up, it won't hurt to tell you."

"The four traits you envisioned—Earth element [Resistance], Water element [Nourish], Air element [Connection], and [Formlessness]—are rare, but not exactly uncommon."

"The four elemental traits are: Fire [Explosion], Earth [Sedimentation], Water [Containment], and Wind [Spread]. These four are relatively rare, but you can still find traces of them in the wild, far from human settlements."

"The other elemental traits are quite common. The academy has a stock of unruly elements with these traits."

Beatrice, seeing the student deep in thought, added a few more words:

"Thousands of years ago, when there weren't many spells available, the rarer an elemental trait was, the more secretive the spells you knew were, and secrecy was usually associated with power."

"But things are completely different now than before; the gap between common and rare traits is almost non-existent."
