Shortly before sunrise Mart was running in sportswear around the outdoor training field.
His breathing was steady, he was concentrated, he began to circulate his demonic energy little by little, that's how he began to move faster, yet he was still applying physical strength and expending his stamina. Minutes passed, he was beginning to feel exhaustion, but he did not stop, he took advantage of the moment to intensify his training, until the muscles of his legs began to tremble, he stopped, it hurt a little to breathe, but he continued to breathe, as he had begun to understand the essence of the absorption of demonic energy, he sat in meditation position, managed to absorb enough demonic energy from the environment to partially recover from fatigue, then did a few more exercises to strengthen the rest of the muscles of the body and when he finished he returned to his room with just enough time to bathe, dress and go to the classroom.
"I don't think this muscle pain can be called living to the fullest. In the end I was able to absorb demonic energy, but it was more of an intuitive thing, far from being a demonic energy absorption technique. The biggest problem is caused by the ambiguous knowledge that this body possessed on important topics."
Mart arrived at the classroom and while they waited for the arrival of the teacher who was teaching the class on demonic spells and incantations, he continued to intuitively absorb the demonic energy to make it circulate through his body so he could recover faster.

Professor Ezblanc, with long black hair, white complexion, and eyes whose iris and pupil were similar to the eyes of snakes, dressed in a black robe with golden edges, was explaining his class. Which attracted the attention of the students who saw the steps to perform a spell on the blackboard and changed as the professor continued explaining, however, who seemed more interested was Mart, who did not hesitate to write down in a notebook the steps of those spells that caught his attention.
-...Students, in conclusion, you must correctly perform each step of the incantation to guarantee the efficiency of your demonic spell. Another point that you must not forget, take advantage of Professor Serfira's ancient language class, that will allow you to know in depth the nature of the spells, and thus you will be able to shape them to your liking in the future. - -Those were the final words of the day's class from Professor Ezblanc, who only applauded, causing all the demonic symbols studied to be erased from the board in an instant.

Since the classes were mostly irregular as they gave the students freedom to fully prepare for the expedition to Marrac Mountain, Mart took advantage of the time and went to the library to hand in the two books that had been lent to him earlier and to continue researching some information about the history and powers of demons, the last topic that interested him came after listening to the lectures on demonic spells and incantations.

In the time before the existence of the empire there were dozens of demonic kingdoms, which lived in constant dispute, as the kings at the helm of each kingdom craved the resources that their peers possessed.
At that time, in a kingdom called Algiers, a talented king, only 19 years old, named Acad Veriz, or also known today as Acad I, ascended the throne. According to stories and chronicles, Acad was a dazzling being, both in appearance, knowledge and power.
King Acad Veriz lived in peace in his kingdom until he was 100 years old, when tired of listening to his ministers asking him to create a map with which to definitively delimit the territory of the kingdom of Algiers, he decided to go further and on an old map, in which the many demonic kingdoms could be seen, he drew some lines with an obsidian feather that he had obtained from a demonic bird, then he told his ministers:
"Ministers prepare, because in less than 60 years I will have conquered this territory and will become the emperor of demons. The work that an Empire entails will also fall on you."
Although his statement was controversial, his stance gained strength when he eradicated three royal lineages that opposed him to the end, other kingdoms offered to follow him and he told them:
-I want no words, send your best men for war, and your most beautiful daughter to become part of my Harem, only then will I have mercy.
The conquest went on, there were many minor kingdoms, which complied with Acad's requests and he did not despise them.
When it seemed that the conquest was assured, the Cudernic kingdom, allied with the Asferyiac kingdom, fought a pitched war against the army of the Ardel kingdom. According to records, this war lasted more than a month and resulted in the death of tens and tens of thousands of talented demons. When the war was coming to an end, King Acad himself faced King Ansert of the Asferyiac kingdom alone, while that was happening intense waves of demonic energy spread everywhere, deforming the landscape in which in the end a canyon saturated with demonic energy ended up forming.
With King Ansert's neck in his right hand, King Acad used his left hand to tear off his head.
King Qiriont of the Cudernic kingdom who was married to King Ansert's daughter had already retreated without leaving any known traces.
Thus culminated the period of conquest that just as Acad first stated, lasted less than 60 years.
"Talent, longevity and effort, was what allowed Acad to become emperor of the demonic world, I believe that if in my other world there had been such longevity, most likely there would have been an emperor of the world, as there were some outstanding emperors to whom time did not allow them to continue to achieve new victories and conquests"
Mart closed the book, took another book of less thickness entitled "Cursed Cannon". And walked to the reception desk to borrow it.
-Do you like the history of our republic?" Emy, the library student in charge, asked Mart as she looked at him with a grim expression.
-Yes, it's very interesting. Maybe I'll become a historian? -Mart stated with a slightly joking tone, so as not to be annoying.
-Take it, it's not very popular, but it's good, but if you don't want to. -Emy suggested a book to Mart.
He saw the title, "Glory and Ruin" and just below the title a subtitle, "Fall of the Argaris Empire".
Mart took the book, and said with his charming smile to Emy:
-I thank you, it's good to know different perspectives of history.
It wasn't Emy's intention, but seeing Mart's charming smile made her demonic energy fluctuate, but after Mart left, she just sighed and returned to her gloomy and low-key attitude; She knew that she was not ugly, but at most she considered herself a little pretty, and in an academy where beauties abounded, especially succubi who were one of the biggest temptations for male students, she couldn't help but think that her chance of conquering a young demon like Mart was slim.
