Aura.

Rasmus put the stack of books on the table that he had taken from the bookshelves. He began to indulge himself with the first book he opened, but suddenly he heard soft moans from the corner of the library. He sighed and manipulated the air around him, making it denser so the sound couldn't travel to his ears.

The first book he read was a book about Aura, another form of Mana. It was something that he didn't find in Henry's bookstore.

"Aura is when someone manipulates the flow of Mana. Consuming Mana and turning it into a primal force is basically what an Aura is..." Rasmus read the page he was holding. "Unlike sensitivity levels, Aura can be trained by consuming Mana into a human body, manipulating the Primal Force to its limit..."

Rasmus stopped reading and went to the bookshelves to find information about Primal Force. He had never heard of that because Henry's bookstore was filled with historical events and not much about Mana and magic. Once he got the book about Primal Force, he went back to the table and began to read it.

"Primal Force is a measurement of each individual's strength and how much they can achieve in life. Every human has a different amount of Primal Force, some can barely train and still can outdo some who have trained their whole life..." Rasmus muttered as he learned about Primal Force.

"Primal Force can't grow, but research has found that in the Eastern Neva, Primal Force can be developed through a specific method. Unfortunately, that method is hidden from the rest of Neva and only selected people who have given the opportunity to develop their Primal Force..." Rasmus continued as he rubbed his chin.

Rasmus sat there, wondering about Primal Force and how much he had inside him. Based on the book, when someone couldn't see any progress in their strength, that meant they had reached their limit. It was similar to Mana and its stages, some people were blessed with extraordinary talent while some didn't even have any talent in both magic and Primal Force.

"This world is indeed complex just as Videl said..." Rasmus muttered as he crossed his legs and rested his arms on the armrest. "I need to rethink my plans because I can't do this on my own," he leaned back and closed his eyes.

Once he rested his eyes for a moment, he continued to read the book about Aura. He took in all the information and knowledge about Aura and how to use it. He read all the methods, but they were all too complicated, so he wrote down all the methods and checked the key points of releasing Aura.

"Isn't this basically like how the energy of a battery works?" Rasmus raised his eyebrows as he stared at his own method on the paper after he had found the key points of each method.

Rasmus didn't want to jump to a conclusion until he finished reading the book.

The sun was setting, and he had been reading the book for almost ten hours. He finished the book and found out how Mana and Aura worked in a human body.

"Aura's strength depends on a human heart, bloodstream, Mana flow, and physical body. The product is the manipulation of Primal Force..." Rasmus closed the book and started processing the method he had made. "Just like a battery, the heart is the electrode, the bloodstream is the ions, Mana is the voltage, and the physical body is the battery size and model," he narrowed his eyes as he stared at the spot on the wall in front of him.

Rasmus decided to leave the library and carry the remaining books that he had borrowed. He went back to his room and tried to release an Aura by following the concept of a battery. He didn't want to follow the method that the book provided because it was too complicated and unnecessary.

"If I follow the concept of a battery, it should be like this?" Rasmus furrowed and closed his eyes as he manipulated the Mana around him and entered his body. "Next is to gather all the Mana into my heart," he felt the flow of Mana like a thick blood that moved inside his body toward his heart.

He knew how human anatomy worked and it made things a lot easier for him to move Mana inside his body. His imagination about his body and Mana flowing inside it was vivid as if he was looking at the process with his eyes.

"Then I concentrated the Mana in my heart..." Rasmus twitched his brows because it was a bit hard and quite painful around his chest. "Now, discharge all the concentrated Mana and send them to my body..." He let loose the concentrated Mana while at the same time keeping them inside his bloodstream and nerves.

He opened his eyes and he chuckled in disbelief that he had just created an Aura by simply following how the energy was produced in a battery. His body was light almost like a feather and his heart was racing which made him feel great. He then concentrated the Aura into his right foot and pushed his right foot on the floor as he released the Aura to the ground. The ground cracked and it shook the whole mansion, shocking everyone inside.

Since his room was on the ground floor, the crack affected the foundation of the building. He heard people panicking outside his room and they were all looking around for the source of the immense power.

He didn't care about them and went to the kitchen to drink because he suddenly felt thirsty and hungry, but then Arnoldi barged into his room, finding the source of the problem. He could see the massive crack and a small crater on the floor. His eyes were wide open and his head turned a bit red from anger.

"You! You should know that we don't allow the use of magic in here!" Arnoldi shouted at Rasmus who was casually drinking his water, making the other find out what had happened.

"I didn't use magic," Rasmus responded as he looked at his left hand. He could feel a tingling sensation all over his body, especially his foot which had become numb.

"We are not blind! We can see the damage you caused over there," Arnoldi pointed at the big crack and a small crater on the floor. "Call the Chancellor, she needs to see this." He ordered one of the staff

Rasmus didn't panic and casually leaned against the wall as he held his glass of water. He also wanted to see Lenin's reaction because he wanted to know if she would give him a warning or not.

It didn't take a while until Lenin came in with Julian, and when they looked at Rasmus's room, they saw the damage he had caused. Arnoldi told them what had happened and he asked Lenin to punish Rasmus for using magic in the dormitory.

"There's no trace of magic here," Lenin pointed out as she looked around the room with narrowed eyes. Since she was a Great Sage, he could tell if Mana was used for magic or not.

"It's not magic..." Julian muttered as she walked into Rasmus's room to look at the damage on the floor. "This is caused by a strong Aura..." she furrowed her brows and was unsettled by what she found when she brushed her fingers on the damaged floor.

Lenin and Arnoldi were mildly shocked when Julian pointed out it was caused by a strong Aura.

"Instructor Blackheart, when did you learn to use Aura?" Lenin stared into Rasmus's eyes.

"Just now," Rasmus answered as he showed the book he had read earlier to Lenin.

Lenin couldn't believe that someone could learn how to use Aura which was supposed to be a complicated and dangerous process. She was baffled because the Blackheart family excelled only in magic and not in physical strength. Not a single Blackheart for centuries could handle Aura because they weren't blessed with a big amount of Primal Force.

"(Rasmus Blackheart...)" Lenin stared at Rasmus with her brows furrowed. "(Is it because your parents that you're excelled both in magic and physical strength that you can achieve both at the same time?)" She closed her eyes and shook her head.
