My health recovery is incredibly fast.

...

The next morning.

Xia Zuo woke up from his deep meditation, washed up, and went to the restaurant.

This was the time when the students were heading to their classrooms, and the corridors of the building were filled with high-achieving students dressed in alchemist robes.

The students of Boying Academy have a unique characteristic: the majority of them are apprentices of magicians, while there are very few magician servants.

As the educational center within the Federation, Silvermoon City boasts a very high level of general alchemy education.

The teaching tasks from the trainee level to the proficient level have been delegated to community schools.

Boying Academy is responsible for delivering expert-level teaching content.

Throughout the entire Federation, anyone who wants to learn alchemy at the expert level or above must come to Boying Academy.

Therefore, those who can enter Boying Academy for further study are basically at the level of mage apprentice.

At 7:40 a.m. that day.

Xia Zuo arrived at the poison alchemy room designated on his admission ticket 20 minutes early.

He pushed open the heavy metal door, and a large alchemy room filled with the light of alchemical lamps appeared before him.

A transparent glass partition divides the room into two parts.

An advanced alchemy table, shelves, a desk, a shower room, a wardrobe containing a robe for alchemy, and a chaise lounge enclosed by glass are placed in the outer area near the door.

The professors' glass balls lay quietly on their respective metal supports in the inner area behind the glass partition.

As soon as the examinee entered, the glass sphere slowly floated up from its soft base, and the monitoring guards inside the sphere began to work.

Xia Zuo realized that the test had already begun the moment he stepped into the room.

He went into the shower room by the door, put on the poison-making robe, and then walked to the desk instead of immediately picking up the exam manual on the desk.

The second phase will last for 7 days.

A full 7 days.

Even the deep meditations each night had to be conducted in the alchemy room.

That recliner inside the glass enclosure will be Xia Zuo's meditation space for the next 7 days.

As for eating, drinking, and needing to relieve oneself, all these were solved using the functional medicines provided in the examination room.

The questions in this section have a single, straightforward theme:

To concoct poisons.

Large-scale poison production.

The first step is to produce an elemental toxin that has been refined once, identify all the toxic effects of the product, and produce a base liquid to remove any additional toxic effects.

Even before arriving in the Eastern Continent, Xia Zuo had thoroughly studied the relevant content about refining elemental toxins at Xingye Academy.

Now it's naturally easy to operate.

Xia Zuo left a secret message for An Ru'er in his mind, telling her that he needed to concentrate on refining poison for 7 days and could not be disturbed.

After receiving Anru'er's reply, he spent half an hour familiarizing himself with the performance of the alchemy equipment in the alchemy room, and then entered a state of silent poison refining.

In less than two days, Xia Zuo had produced a table full of poison products.

To remove the additional toxicity, the mixture of the toxin and the base liquid needs to be left to stand for a long time, at least a month.

The exam will only last for 7 days, and there are still a little over 4 days left.

To verify whether Xia Zuo's base liquid formula is correct, we obviously cannot wait a month to reveal the answer.

The second step in this round of examinations is related to this.

The exam manual states that Xia Zuo needs to open the desk drawer, take out the metal box inside, and refer to the instructions inside the box to use the tools in the box to skip the process of settling the mixture.

"What can accelerate the removal of additional toxins?" Xia Zuo scratched his messy hair, reached out and unlocked the metal box, then opened the lid to take a look.

"???" Xia Zuo rubbed his eyes to make sure he wasn't seeing things.

"Circinus?"

He took a magnifying glass and examined it closely.

It really is a ring-breathing insect.

However... the ring-breathing worms before my eyes are not the level 1 painless ring-breathing worms I encountered in the Western Continent.

Inside the metal box were six glass jars, each containing a reddish-brown annular worm slowly wriggling at the bottom.

They have round black spots on their bodies, and tiny fleshy tips protruding from their bodies. Some of these tips are quite long and glide through the air like tentacles, seemingly sensing changes in the airflow or smells in their surroundings.

The instruction manual inside the metal box states that these ring-breathing worms are codenamed Level 4 Painful Ring-breathing Worms within the alchemical school.

These ring-breathing insects, after being processed through bioalchemy, can be formulated into expert-grade, perfect-quality breathing medicines.

Those who take this secret medicine and can withstand the intense pain will randomly gain three beneficial mutations, ranging from the basic functions possessed by Type I to Type IV alchemical implants.

At the same time, the user will also randomly acquire 0 neutral mutations, ranging from [the basic defects possessed by type I to type IV alchemical bio-armor].

Xia Zuo took the instruction manual, sat down at the desk, and read the above passage carefully many times, his mind filled with countless thoughts.

Based on his years of alchemical experience, he deduced a great deal of useful information.

The "4th grade" of the Level 4 excruciating pain ringworm refers to the quality of the ringworm itself, and the corresponding breathing technique medicine is of expert grade.

According to the conventional naming and grading methods of the alchemical school.

"Level 1" Cyclops, corresponding to the breathing technique secret medicine for trainees.

"Level 2" corresponds to the beginner level.

"Level 3" corresponds to the proficiency level.

Level 4 corresponds to the expert level.

Level 5 corresponds to Master level.

Painless, painful, and excruciating pain are three different levels of pain, representing three qualities: passable, excellent, and perfect.

After taking the breathing technique elixir made from a level 4 ring-breathing insect, the random range of both beneficial and neutral mutations falls within the basic functional range of the [Type I] to [Type IV] alchemical bio-armor.

It is not difficult to deduce that the grade of the ring-breathing insect determines the random range of mutations caused by the secret medicine of the breathing method.

Before the Type VI and Type VII Hidden Tail Serpents were intercepted by the Mage Temple, the Type I to Type V were circulating in the market, which corresponded to the Level 1 to Level 5 of the Ring Breathing Insects, that is, the Apprentice to Master level of the Breathing Magic Elixir.

The mutations caused by the breathing technique elixir made by a level 5 ring-breathing insect will be randomly selected from the basic functions of alchemical bio-armor ranging from type I to type V.

The number of mutations obtained after taking the secret medicine for breathing techniques is related to the quality of the annular parasite.

The painless ringworm can produce a passable respiratory medicine, triggering one beneficial mutation and one neutral mutation.

The pain-inducing ringworm can be used to create a high-quality respiratory medicine, triggering two beneficial mutations and 0 to 1 neutral mutation.

The Painful Ringworm can be used to create a perfect breathing elixir, triggering 3 beneficial mutations and 0 neutral mutations.

Then the problem is coming.

Which came first, the Cyclops or the Alchemy Bio-armor?

It's highly likely that the alchemical implants came first.

One could even speculate in this way.

The so-called Ring-Breathing Worm is actually made from the bone sac, the main material of alchemical bio-armor.

This idea sounds absurd, but Xia Zuo is able to provide evidence.

Because the instruction manual for the annular worm states:

[Soaking the Level 4 Painful Ringworm in an Expert-grade, Perfect-quality base solution can accelerate the removal of the additional toxicity of Expert-grade and Perfect-quality poisons, and reduce the Ringworm's grade by 1 level, while maintaining its quality.]

Below this sentence, another sentence was written in bold:

The grade of *Cyclophorus* can only be lowered, not raised.

In other words, the existing annular worms below level 5 are all descended from level 5, not ascended from level 1.

This is a process of cracking the code step by step.

This is further linked to the fact that the Yizhu Group collects bone sacs.

Xia Zuo roughly deduced what this logical chain was like:

1. In order to accelerate the training of hybrid mages, the Church of the Otherworldly Demons used bone sac alchemy to create a large number of bone sacs and deployed them deep inland.

2. The Alien Group dispatched a team of detectives to collect bone sacs.

3. The Heterogeneous Group handed over the bone sac to the alchemy school of the Mage Temple, who used bioalchemy to transform the bone sac into a Ring-Breathing Worm. The quality of the Ring-Breathing Worm is determined at this step and cannot be changed.

4. Poison alchemy has discovered that the removal of additional toxic effects can be accelerated by the Ring-Breathing Worm, and that the Ring-Breathing Worm can be downgraded.

5. The bio-alchemy and toxicology teams collaborated to reduce the Ring-Breathed Worm to a suitable level and create a Breathing Elixir, which was then delivered to the Warriors Guild.

The entire chain is equivalent to harmlessly treating and reusing the bone sac, transforming it from an evil product of bone sac alchemy into a key ingredient for breathing techniques and elixirs controlled by the Mage Temple.

After Xia Zuo roughly figured out the cause and effect, several more questions popped into his mind.

How does the bone cyst transform into Cyclops?

How does the anthracidus cause mutations?

Why can the ringworm accelerate the shedding of additional toxicity and take this opportunity to downgrade?

After the Hidden Tail Serpent Type VI and VII were intercepted by the Mage Temple, did the Alchemy School develop an alchemical method to transform the bone sacs of these two types of alchemical bio-armor into level 6 and level 7 Ring-Breathing Worms?

Xia Zuo rubbed his temples, feeling a slight headache... Sometimes, having a fast mind isn't a good thing; it can easily overwhelm you with the sheer number of questions you've unearthed...

Solving one problem leads to another, and then a series of follow-up questions…

The worst part is that these questions remain unanswered for the time being, and can only be kept on our minds.

Rexor previously stated explicitly:

After passing the advancement test to become a master-level poison alchemist and completing his advanced studies at the Mage Temple, Xia Zuo can enter the biological laboratory in Poseidon City to conduct research.

There will be plenty of opportunities to answer the questions in my heart in the future.

At this point, the exam is more important.
