The man wore a well-tailored gray pinstripe suit, a dark brown silk tie at his collar, and a knee-length trench coat of the same color hung on a coat rack in the corner of the classroom.
He looked young, yet possessed the dignified air of an elegant old professor.
He turned away from the glass window covered in beautiful writing and returned to his lectern.
Many students continued to gaze in the direction of the glass.
Even without considering the meaning of what he had written, the rows and tree diagrams formed by the script possessed a captivating beauty that made it difficult to look away.
"The rapid development of the field of magical engineering over the past century has not just been a step forward, but a gradual opening of new ways to understand the world. Someone has opened a door for us, and we are peering through the crack, seeing a hidden world within our own, a world full of energy, contradictions, and, in the eyes of some, unacceptable things."
Standing on the podium, he spoke to the many students sitting in the auditorium-like classroom below.
The chimes of Elliot Hall rang, creating ripples in the air and mist, yet failing to distract the students.
"Magical engineering is like sheet music. The point isn't 'Can you read the notes?' but 'Can you hear the music?' Can you hear it?"
He tapped the podium, his gaze seeming to meet that of every student.
"I can."
The classroom fell into a brief silence, followed by many students nodding gently, as if their hearts were surging.
At the very moment that Lancel's lecture was underway...
"Professor, where do we find the fuel?"
The question came from a rather refined-looking female student with vertical pupils, whose act of speaking before raising her hand could only be described as eager.
She had been calculating rapidly on paper and pen, and immediately came to this huge question and raised it.
However, Lancel's classroom management was always free-speaking and he wouldn't mind the impetuousness of the students.
Among this group of students, besides humans, there were also a few beastfolk.
Among the three major territories that originally composed the Kriti Empire, the Cyros Empire was almost a purely human empire, the Elsayah Sanctuary had a small number of elven descendants and rare races, and the Winsey Free Federation contained beastfolk lords.
Although humans still predominated after the unification, one could occasionally see Kriti people with beast-like features or pointed ears on the streets and among the nobility.
For example, Bianca, the Cat's Eye Stone Seat, the last of the Twelve War Gods, was a cat person, and Ryan, the ninth war god of the Amethyst Seat, possessed Griffin blood.
"The Kriti Empire's military energy cannot be used for civilian purposes."
Before Lancel could answer, the other students in the classroom had already begun to think.
"This theory sounds promising and innovative at first, but realizing it is like trying to fit a dragon into a cabinet."
"Can it really be done?"
Most of them listened while their pens and calculations barely stopped, and they quickly realized this problem.
That is, where does the ultra-high quality energy and raw materials that can trigger special explosions come from?
If this problem cannot be solved, it is nothing more than empty talk.
Thalia was also wondering in Lancel's mind.

Lancel's explosion principle is essentially a composite attribute of [Fire] and [Seal], which also includes the characteristics of the seal system –
Cost-free sealing techniques often require a medium.
Otherwise, the caster will suffer a great backlash.
And the best framework medium is often related to regeneration, which can positively and negatively offset the cost of the sealing technique.
Since there is no high-grade recyclable material like [Wolf King's Pride] as the core, then you need to find a lower-level substitute.
However, with the family resources of this group of students at Saint Kriti Monastery, it is not impossible to obtain pink sacred-quality regeneration materials in the Kriti Empire. If the material itself also has sealing suitability, it will be even more powerful.
Of course, what is more important is the technology, debugging, and consumables.
"It will be done. Don't you think that if we can develop a new energy source, it might become an even greater topic?"
Lancel's expression remained unchanged, and he looked at the students as if standing at the finish line, affirming.
"New energy?"
"A new energy source that can be applied to this military level..."
"To compress the density to such a high level, you can't just find a bunch of epic magic guides to refine, right?"
There was another burst of sound in the classroom, and even the mention of epic magic guides caused laughter.
After all, if you could really find an epic magic guide, no one would blow it up.
If you can find a small, high-density energy source to replace the epic magic guide, it may be a greater research topic than the new type of bomb itself.
For the current Kriti Empire, if there is such an energy source, Professor Landry would probably be directly invited to the Imperial Weapons and Equipment Department as a consultant, instead of standing here.
"Of course, this is another project that is being researched. It is not in the form of lectures, but work in the research institute. I will only recruit a small number of students with [Alchemy] attributes to assist me."
Lancel just promised,
"You don't have to worry about the energy source. I will directly provide you with the results of this research. Within a month, I will issue you the energy source for testing. It will probably be granular, liquid, and crystalline red substance."
There was a sudden commotion in the audience. The auditorium was full of senior students, who looked at each other in surprise.
Professor Landry's research is too cross-century. He seems to be studying the creation of gods, which makes them wonder whether the professor is telling the truth or going crazy.
This is not civilian magical engineering at all, but pure imperial military industry!
"Where did you get the energy?"
Thalia didn't understand what Lancel was referring to.
High-performance bombs are okay. She knows what the principle is. After all, she watched Lancel bomb from first-level to sixth-level and enjoyed it. He seemed to be born to research bombs.
But she, as Lancel's most beloved and dearest teacher, had never heard of the divine energy source Lancel mentioned.
Miss Unity, the Allied assassin she met on the Brillda magic rail train last time, will come to him sooner or later. If she learns about the magical engineering principles he teaches at Saint Kriti Monastery, she will definitely come to him directly.

"Tata, have you heard of the Philosopher's Stone?"
Lancel asked her.
"What is that?"
Thalia replied with a thought.
"The Philosopher's Stone is an extremely powerful alchemical item that can ignore the basic rules of alchemy - equivalent exchange. This means that alchemists who use the Philosopher's Stone can create or transform matter without providing corresponding value. The manufacturing process of the Philosopher's Stone is actually made by refining a large number of human lives, which makes it highly morally controversial."
Lancel replied.
"Does this kind of thing really exist...?"
Thalia recalled that there seemed to be something similar in demon legends, but it was just a rumor. She had never seen it and had no way of knowing the secret recipe.
According to Lancel, even if it exists, the Philosopher's Stone cannot violate the principles of alchemy. The conversion rate will be quite low, and it will take a sacrifice at the level of national destruction to create a Philosopher's Stone with the power to destroy a country.
"It exists."
Lancel replied.
"How do you know?"
Thalia asked.
"..."
Lancel was silent.
"..."
Thalia was also silent.
You little brat, you wouldn't have a recipe, would you?!
"It is certainly unethical to use humans to refine them, but there is one species that is different. They suck human blood every day, and their survival process is inherently similar to the refining of the Philosopher's Stone. Using them to refine them is equivalent to confiscating illegal gains."
Lancel explained to Thalia seriously,
"Under the joint research of the Necallis Research Institute and the modern technology provided by me and the great poet, Esmode, a talented demon woman, has almost made its prototype. We just need to capture enough vampires to refine it into a Philosopher's Stone."
Back then in Demon King's Castle, the Fourth Progenitor Eduardo and the Tenth Progenitor Ulysses, who were captured, were too powerful, and their blood was not easy to refine into energy. On the contrary, Count Gregory, who was captured in the Land of Eternal Night together with Sigrid, was easier to refine into semi-finished Philosopher's Stone.
There are no vampires to catch in the Herton Kingdom. Now that he has come to the Kriti Empire, Lancel's research project can finally be advanced.
"What kind of taboo things are you playing with!"
"Don't worry, Tata. When my research results are released in the Allied forces, I will add a thank you to you. After all, the follow-up work still requires you, a modern talented demon woman, to work with me to improve it."
"You are not thanking me, you are framing me!"
She felt a little like reporting this human being.
If Lancel wants to add her name to the journal, she will get angry with Lancel.
During the Holy War of the Demon Race, the Demon Race rarely considered using a large number of living people for human body refining to transform high-quality concentrated energy.
The higher-level vampires are naturally undead creatures that have been refined by countless humans, and the biological energy contained in them is equivalent to countless times that of humans.
This guy, in addition to basking in vampires, eating vampires, and detonating vampires, is now starting to study vampires and refining them.
How much did you hate vampires in your last life that you are torturing them like this in this life.
The noise in the large classroom deep inside the fourth floor of Elliott Hall fermented for a while before Professor Landry on the stage spoke again.
"On the basis of ensuring the course objectives, I may add some content that is not included in the original syllabus. Of course, these parts are all up to you to decide whether to learn voluntarily. They will not be included in the assessment, and more students are welcome to audit. This is an open classroom."

He looked at the students,
"Regarding the new energy source, I will probably make the principle public after the technology matures. I will definitely hand this thing over to the country without hiding it. And I am standing here to pass on knowledge to you. The future of the Kriti Empire cannot rely on any one person, but on everyone, both me, you, and us."
Covering his own unique magical engineering in a course undoubtedly meant that the lecturer had reached the ultimate field of his specialization.
Although the students in the audience were skeptical about the new energy source, as long as they looked at the content on the glass that they could not digest in a short time, they felt that this professor was unlikely to be someone without real skills.
"Interesting."
A clear voice sounded almost imperceptibly in the seats of the noble students on the right side of the classroom.
Hearing this, Elsa Washington, who was concentrating on listening to the lecture in the gathering circle of commoner students on the left side of the classroom, trembled.
She quickly concealed it skillfully and looked keenly at the noble girl in the distance.
The person she was staring at from a distance was a girl with blue eyes and purple hair. Her skin was as white as if it were transparent, and her exquisite features were like works of art under the hands of a craftsman, with a boyish handsomeness, making her unable to look away for a moment.
Seemingly noticing her gaze, the blue-eyed and purple-haired girl also looked towards Elsa Washington.
"Ursula, don't mess with my brother, okay."
Elsa looked at the other party with some worry, and told the other party silently and anxiously with lip language from a distance.
She looked again at Landry, the brother on the podium who felt a little strange to her, but was always mysterious.
She didn't expect that their siblings would meet again in the classroom of Saint Kriti Monastery.
"What do you mean I want to mess with your brother?"
The girl named Ursula looked at Elsa as if she was angry, but her lips and teeth were a bit playful, and she even narrowed her eyes.
"..."
Elsa stopped staring at the far right of the classroom, wasting time with that real high-ranking noble.
Ursula Rowland.
The Rowland family is one of the most prestigious families in the Santa Empire, and Ursula is the sister of Ryan Rowland, the current Marquis and Ninth War God. She has known Elsa since advanced school.
She lives up to the name of Griffin's daughter, combining beauty and talent.
As a student who quickly became famous after enrolling in the School of Magical Engineering at Saint Kriti Monastery, Ursula's prominent family background, stunning appearance, and outstanding talent are all enviable.
However, geniuses are often difficult to tame. Such a nearly perfect girl always does strange things. For example, at this moment, she always likes to do what she wants, without worrying about whether her behavior will be out of demeanor or disgrace her family.
She seems to always make Marquis Ryan angry, but the Marquis never pays attention to her.
In the eyes of the teachers at Saint Kriti Monastery, Ursula Rowland is nothing less than a living bomb. Once she finds that she cannot please everyone, she will try to make everyone unhappy.
And because she has the Ninth War God Amethyst Seat Ryan, the Marquis's brother, no one dares to retaliate against her.
When she learned that the teaching teacher was Landry Washington, who was new and unknown, the curious smile on Ursula's face made others feel uneasy.
She and Elsa are both low-grade students who are among the few in this Level 4 course. They have known each other for a long time and are full of interest in Elsa. It is not surprising that she will target Elsa's brother.
"May the goddess bless, and give some of my merit to my brother."
Elsa lowered her head and muttered, and could only desperately pray for the blessing of the Goddess of Destiny, and hoped that Landry's brother could deal with Ursula for the sake of her continuing to do good and accumulate virtue.
