A crosswalk world was a type of world wouldn't assume you as an enemy when you entered. Most worlds would have a defense mechanism to protect its habitants from the intruders and that mostly would be fueling the attack impulses of the inhabitants towards the intruder.
The crosswalk worlds didn't have such mechanism, rather they could grant you opportunity to become a some sort of citizen. ["If Teacher Fiona was telling this, that means there was something to gain there"] thought Leon. But that wasn't important right now, he needed to create his Soul Artifact. After the lesson finished he went to library and read more books and get inspiration. When he entered inside of the library he got the inspiration, he could create a book as a Soul Artifact but he didn't want to create a normal book. The book he wanted to create should be more like a computer. He wasn't a programmer but he could research the tower spirits and use them as a foundation.
Finding the type he went to the sections about the tower spirits. There were massive amount books in the section but he had the time. He took a book and sitting on a table, he started to read it. The inscriptions needed to create a tower spirit was very complicated and hard to understand for Leon but he didn't care he only needed to create the core and rest could be made after.
After deciding type of his Soul Artifact, his days became more and more monotonous, he also asked after a few days in the tower spirits to Teacher Fiona about it and she said it would be okay and there wouldn't be a danger. Also she said that her Soul Artifact was similar to his. After getting green light from Teacher Fiona, Leon dwelt into his research. As he researched, he wrote the inscriptions to the papers.
After a month, one day while he was doing his research, he looked outside and noticed it was noon. He gathered his papers and put the books to their places. He already form the core of the Soul Artifact and the core of the tower spirit which he had was great help to form it. All he needed to do was to use soul crystal to condense it.
But before he condensed his soul artifact, he needed learn about the crosswalk world which he would go. Leon asked librarian the books about the crosswalk world and he found the books then he started to read them.
The crosswalk world that he would go was higher plane from Aroan world. The world has system in it, using this system the inhabitants of this world could learn a lot of things easier. And because of it, this world also called System world, nobody knows why this world gained this type of consciousness but everybody gaining something from it. The system would install a seed in the sea of consciousness. When someone made a contribution to the world, they can gain rewards from the worlds system. All inhabitants of this world born with their open sea consciousness without a open sea consciousness one couldn't gain rewards. That's why the academy sent the students with open sea consciousness.
Rewards were soul techniques and abilities or in extreme cases tempering your soul but it didn't mean you could only gain rewards related to soul. The system world also had some materials which was extinct in Aroan world. This world was specialized on soul techniques and most of the techniques about soul. Doing quests and gaining abilities would make students stronger so the academy would send the students to gain abilities from this world. Also this world didn't just gaining contribution from its habitants also from world travelers, it was truly a win-win situation for everyone.
After gaining general idea about the system world, Leon leaved the library and went to his room. He was staying himself and didn't have any connection with anyone in the academy so he wasn't afraid of interruption of his meditation. But he hanged ["Do not disturb"] as a notice in any case.
Leon sat down on his bed and brought out the soul crystals and his research papers, he checked for the last time and took a soul crystal on his hands then he closed his eyes then he started to imagine a book which could store all knowledge and can make deductions like a tower spirit. It was the first step to condense a soul artifact. Leon needed to gave a purpose to the soul artifact and he needed to impose his belief and faith to it. Stronger the properties of the soul artifact, more it consume soul crystal to form. After a minute or so with a glass breaking noise, soul crystal lost its luster and turned to dust. Leon bought enough soul crystal to breakthrough to soul embryo, so it didn't bother him.
He already consulted to Teacher Fiona about his soul artifact and she said it would take more soul crystal to form his soul artifact, he was already prepared to consume a lot of soul crystal. One after another the soul crystals turned to dust in front of him to make a small sand hill, only after thirtieth soul crystal, his soul artifact ruffly formed.
The soul artifacts were like engines, like engines they also need some sort of fuel. When sea of consciousness was opened soul artifacts could consume mental energy from it and could temper mentality and made it more pure. Leon didn't opened his sea consciousness but he consumed a lot of remnant mental energy from the corpses in the Blackwood forest so the initial tempering was a must for him.
Because he didn't open his sea consciousness, he didn't "see" what the soul artifact was doing but he could feel his mentality becoming more free and the shackles which he didn't know breaking apart. He felt like he was in a room without ventilation and newly inhaled a fresh air. After losing himself in this feeling a bit he continued to consume more and more soul crystal so he could open his sea consciousness. When the lasts of soul crystal remained, he felt like, he took a blow to his head then he could "see" a sea and above the sea there was a book which constantly inhaling and exhaling the water of his consciousness. The water which was entering the book was muddy and he could see faces on it, Leon knew these faces. They were the ones Leon possessed and took their knowledge. It seemed that he also got their obsessions with it. The water coming out of the book was pure and Leon could see his face on it. Leon stretch his hand towards the book and book came before him and opened. Leon could see all the knowledge he gained from corpses was in it.
Even though the book was half done, it could store information, the second phase of the book was to make deductions but it would take some time to upgrade it.
"From now on your name is Book of Knowledge."
