Konoha Medical Department, Division Commander's Office
At this time, a figure sat in the original Tsunade's position, silently refining Chakra. This person was Aizen. His clothes remained the same as before, a testament to his unwavering determination. But his most significant change was his height! He had reached a height of one meter six or seven, almost indistinguishable from some adults.
Anyone who has raised fifteen or sixteen-year-old children, or has siblings at this age, knows that at this age, it is the period of most rapid physical development. He had shot up in the blink of an eye.
Now Aizen, not only taller, was also more angular and handsome. With his disguised gentle temperament, he could be called a heartthrob among young girls. In the past two months alone, Aizen had received a box full of confession love letters. However, Aizen politely rejected these passionate girls. And when he got home, he immediately burned this pile of "garbage," flushing the ashes down the toilet.
Let's return to Aizen. At this moment, as Aizen finished refining the last trace of Chakra, he had also successfully entered the ranks of Elite Jonin!
At the same time, his Reiatsu, Shunpo, and Kidō skills would be improved to a higher level after a few days of familiarization and mastery. Aizen's strength would also experience explosive growth once again.
"Exhale!"
Aizen let out a breath of turbid air, opened his eyes, felt his state, and nodded in satisfaction. After a few days, his Reiatsu had also risen to the level of Elite Jonin. Then his overall strength, in a short period, even in a head-to-head battle with Mitarashi Zashi, he wouldn't be at a disadvantage! If he were to use the Flying Thunder God Technique and Kyoka Suigetsu again.
Aizen had absolute confidence that he could achieve victory! That's right, in this year's time, Aizen had basically mastered the Flying Thunder God Technique.
Not only could he create his own Flying Thunder God Kunai, but he could also leave a Flying Thunder God mark with his bare hands! Even the ability of Flying Thunder God's instantaneous teleportation had been initially learned.
At this point, Aizen's strength was already comparable to a powerhouse at the peak of Kage-level! In the entire ninja world, he was a true top powerhouse!
Of course, if he encountered Hatake Sakumo. Aizen would likely still have to rely on the Flying Thunder God Technique to escape. Even if he reacted quickly enough to activate the Flying Thunder God Technique, it might be a little too late. The road to becoming the strongest was still a long one.
Thinking of this, Aizen sighed inwardly.
However, this year, Aizen's greatest gain was not the growth in strength. Aizen's thoughts moved, and from his soul, a black bead emitting a faint blue light suddenly appeared!
This bead wasn't large, only half the diameter of Aizen's thumb. Then, the bead emerged from his palm, suspended in mid-air.
Looking at this bead that exuded a strange light, Aizen's eyes were filled with endless ambition and obsession! This thing was the Naruto version of the Hogyoku that he had exhausted countless efforts to create over the past year.
This Hogyoku was primarily made from the root of the God Tree! It could carry and absorb any kind of energy and genes in the ninja world! Then, through a transformation ability, these energies and bloodlines could be perfectly transferred to Aizen!
This was Aizen's special creation, combining the biotechnology of the three worlds: the Soul Society, the Human World, and the Ninja World. At the same time, he had also created a cheat for himself.
Aizen's actions profoundly illustrated a truth: It doesn't matter if you don't have a cheat after transmigrating! What's the big deal? Create one yourself!
"I'll just make one myself and be done!"
Of course, it wasn't all smooth sailing. Not to mention the root of the God Tree, which had mostly disappeared. The experimental materials needed to test the Hogyoku's absorption and conversion of energy and genes. Namely, the cell tissues of Nawaki Senju and Senju Ryuken that Aizen had obtained before. Had been almost completely consumed by the failed experiments at the beginning!
This made Aizen cringe with pain. The Senju bloodline was extremely precious, and he had originally wanted to use them for other biological research. But for now, that was out of the question. Because the surviving Senju direct descendants, apart from himself, were likely only Tsunade.
"Ah, yes! I also have my teacher as backup material, don't panic, don't panic." Aizen kept comforting himself while saying outrageous things.
Of course, with this cheat, it seemed that Aizen had the ability to plunder any bloodline in the Naruto world. But it was only the Hogyoku that could handle all kinds of conflicts, not himself! If he randomly absorbed some abilities. In the end, it would definitely be rejected by his body, leading to an explosive and fatal outcome!
Therefore, Aizen's use of the Hogyoku to plunder bloodline abilities had to be carefully considered! In the Naruto world, the most valuable and potential abilities, and those that wouldn't cause rejection after fusion and could even evolve further, were limited. Sage Body, Wood Release, Sharingan, Byakugan, Shikotsumyaku.
Aizen's mind flashed with these bloodline abilities that shook the ninja world, and he secretly made up his mind.
After Aizen finished thinking and stabilized his state, he walked out of the office.
"Hello, Vice-Captain Aizen!"
"The vice-captain is so handsome!"
"Yeah, Vice-Captain Aizen is not only powerful at a young age and holds a high position, but also has a very gentle personality!"
Along the way, in addition to the people who greeted Aizen respectfully, there were also many infatuated young girls whispering around him.
Half a year ago, when the system of medical ninjas entering combat teams was initially completed, Tsunade chose to leave Konoha. Before leaving, she specifically promoted Aizen to the position of deputy captain of the medical unit, managing all affairs of the medical department.
The current Aizen was not only a high-ranking figure in Konoha in terms of identity! His actual authority made him a true Konoha high-ranking official! His position of power was far from comparable to before.
However, just as Aizen routinely responded to these people, a strange figure suddenly caught his attention. It was a boy who looked to be only about twelve years old. His body was a bit thin, and the white clothes he wore were relatively loose. He had silver-white hair and looked quite handsome.
Of course, what attracted Aizen the most was that the boy always had a fox-like smile on his face, and his eyes were narrowed like a fox's. And, from the small slits in his eyes, a pair of pure white pupils could be clearly seen!
A member of the Hyuga clan?
Seeing this, Aizen raised his eyebrows, and a hint of interest appeared in his eyes. Although the Byakugan of the Hyuga clan was indeed very suitable for medical ninjas, this traditional great ninja clan prioritized their own fighting strength, and it was almost impossible for their own children to join the medical force. That was quite interesting.
"Who is that white-haired boy?" Aizen stopped and asked a male medical ninja next to him.
The man was stunned for a moment, then after looking in the direction Aizen was looking, he hurriedly said respectfully: "Lord Aizen, he is a medical ninja trainee who has just entered the medical department, from the Hyuga clan, his name is Hyuga Gin!"
