Huge Amounts of Progress

From then on, Rai began honing his kunai throwing skills on trees, experimenting with throwing kunai attached to wires. An idea emerged – channeling lightning chakra into these wires for added effects.

Rai maintained his commitment to both his apprenticeship with Lō and his academy studies. His skills were gradually improving: his chakra control was his forte, his chakra size marked him as a high-genin, his chakra control reached low-chunin level, and his taijutsu, augmented by the academy curriculum and his personally developed style, elevated him to high-genin status.

With his dedication, Rai's pay at the weapons shop increased to 800 Ryo. Eager to learn the basics of fuinjutsu, he approached Lō with the request. Lō's cold stare was replaced by a rare seriousness. He voiced his concern, questioning if fuinjutsu would hinder Rai's progress at the academy.

Rai shook his head, adamant that fuinjutsu would enhance his abilities rather than hinder them. He explained, "I'm at the top of my class, and all I do is train. Incorporating fuinjutsu wouldn't hinder my progress; it would strengthen it."

Lō relented, handing Rai a book. These were Lō's own notes on the beginning stages of fuinjutsu. Rai thanked him and left with a joyful smile.

In his apartment, Rai took a long shower after changing out of his academy clothes. Seeing the fuinjutsu book on his desk, he sat down and delved into its contents. Fuinjutsu, he learned, consisted of two main parts. The writing aspect had its own complexities, involving special seals, precise symbol drawing, and chakra infusion. Mistakes could lead to unintended outcomes.

The second part involved molding chakra to enact the seal's purpose. Rai discovered storage seals, elemental seals, and even space and time manipulation. If he wanted to master them all, it would require months of dedication.

Having finished the book, Rai went to bed, anticipating the next day. He continued attending the academy and classes as usual, visiting the library afterward. He explored the genjutsu section, opting to learn "Demonic Illusion: Hell Viewing," a D-rank technique.

Additionally, he delved into the potential of lightning techniques:

E-Rank - Static Coat E-Rank - Electric Spark E-Rank - Static Step E-Rank - Lightning Beacon D-Rank - Lightning Ball D-Rank - Thunderous Echo D-Rank - Electrical Dart D-Rank - Lightning Bolt

During the shinobi academy's vacation, Rai was seen meticulously crafting a paper bomb, using skills gained as a weapons inventor's apprentice. His mastery extended to crafting paper bombs and sealing scrolls. He had also fully mastered the D-rank genjutsu "Demonic Illusion: Hell Viewing" and advanced to learn the C-rank technique "Demonic Illusion: False Surroundings."

His proficiency extended to all the lightning jutsus he had picked. Rai marveled at his high affinity for the lightning element, pondering if it was his unique advantage in this world. He had also gained a solid grasp of "Demonic Illusion: False Surroundings," although complete mastery was still a work in progress.

Furthermore, he learned how to infuse lightning chakra into his chakra wires, enhancing his versatility. Rai had become one of the most well-rounded academy trainees, possessing an impressive arsenal of jutsus.
