More than a week later.
Mart had gotten up early, going out to train before his classes started, his severe fatigue had ceased, so he began to infuse his demonic energy into every muscle of his body as he ran on the training ground at a speed close to the speed of a demon at the Third Rank.
While he ran through the outdoor training field, he also inhaled and exhaled with a constant rhythm with which he was seeking to gradually increase the capacity to absorb demonic energy according to the amount of energy expended.
Mart ran until he felt like his muscles were about to tear, he didn't think about the pain, since the training hurt less than the pain he suffered during the time he was recovering from severe fatigue.
When he finished running he sat down to meditate in the middle of that open air field, he circulated his demonic energy through every corner of his body, when he felt that he had recovered enough, he performed some complementary exercises, since although he was not thinking of becoming a warrior, he knew that he should at least have an average physical condition to stay healthy, since he did not want to be a wiry and gloomy demonic wizard.
When he returned to his room, he found Asfil, she was wearing her school uniform, whose short skirt looked beautiful with those long, slender legs, and whom he had only seen during the first classes after the Academy resumed classes.
-Come in. -Mart said after opening the door.
Mart went into the bathroom and Asfil sat in the chair in front of the desk, after a few minutes Mart came out covering himself with a white bathrobe and sat on the edge of his bed, he looked at Asfil who was looking at him closely.
-What's wrong? -Marc asked in a relaxed tone.
-What happened to you? -Asfil inquired directly.
Mart knew what she was referring to, he knew she was suspicious of him, both because of the questions and because of what happened with the letter.
-Is it important? -Mart asked, smiling subtly.
But Asfil didn't think it was funny, showed some anger and said:
-Something happened to your memories. Did they do something to you?
-You look worried, but what will change if they did? -Mart said as he stroked the hair on the left side of his head.
-I'll stay away from you, completely; what do you think will happen if you get your memories back? You'll be the same scum as before; but if you trust me..." Asfil paused.
A smile of subtle malice appeared at the corner of Mart's lips as he stood up, walked towards her, leaned towards her and asked her with a smile that mixed kindness and malice at the same time:
-What will happen if I trust you?
Asfil kissed Mart, then ran to the entrance of the room, and told him in a firm tone that did not hide her blush:
-I will help you, if you need help.I will never doubt you, nor will I ever turn away from you as long as I live.
She closed the door, Mart sat in his chair, in the last week he had been searching among the few useful memories of the real Mart, and realized that Asfil's grandmother was a human, Mart did not mind that at that moment, but after thinking about it he considered the situation complicated, since he considered that given the human greed that he himself knew because he had been a human before transmigrating, it was best to stay away from them.
Thus he considered that the only humans he would accept as allies would be those who had no attachments or ties to the human race, and that was something very difficult to find.
Mart made that decision, because he felt that only then could he save the country from demons.

A few days later
In the classroom of class B, Professor Derec Mesef, a demon with red skin, black horns, black hair, tall, wore a formal brown suit and taught classes on demonic energy, he was also the current B class advisor.
Young people should know that the demonic energy is the product of the concentration of different compounds found in our environment, whether the areas with concentrated demonic energy or the beings that possess demonic energy, all have a core that is nothing more than the heart of the demonic beings, but that core after much study, it has been proven that it has a composition similar to that of the demonic stones!
Professor Derec who was explaining his class took out of his ring, three beautiful gems, and made them float so that the whole class could appreciate them, one was light blue like the sky of the day, another was of a crystalline green, and the last one was red and shiny.
Several students looked amazed and others did not look very happy. But the professor paid no attention to them, just continued with his lecture with the knowledge of a professional.
These stones are called magical gems by humans, their value is high, but their importance lies in the fact that they are forms of concentrated mana, with elemental characteristics, capable of containing large amounts of the elemental energy they represent, and not only contain it, they release it, maintaining their efficiency for a longer time than demonic stones and mana stones resist; that efficiency and durability make it similar to this demonic core!
Some students exclaimed in surprise at the sight of a demon core, which was actually bright purple and spherical, but still contained concentrated demonic energy; demon core that was actually the heart of a demon.
"This would be like showing the humans in the middle of a class, a freshly extracted human heart," Mart thought wryly, but then he put his hand to his chest for the first time and felt nothing but the flow of energy circulating through his body spontaneously, "Wow, apparently I don't have a heart; expect no mercy," Mart joked in his mind.
A few minutes later Professor Derec left the classroom but his dissertation had left quite an impression on Mart, so he decided that when classes were over he would go to the library to look for books on demonic cores.
