This kind of Reiatsu, purely determined by the talents of the deceased, and whether one can become a Shinigami, has an extremely rough condition for formation.
Although Yamamoto had possessed him, and Rojen was completely clear about the composition of a Shinigami, he had no intention of committing suicide to form such a spirit body. There were too many powerful individuals who could possess him, so why hang himself on this spirit body?
"Without becoming a Shinigami, Reiatsu cannot be maximized, and the power of the Zanpakutō naturally cannot reach its limit."
"Such power isn't of much help to me right now."
On the other hand, the possession coins this time had reached a whopping 240 Million, which made Rojen quite pleased.
Even if old man Yamamoto couldn't bring him any substantial benefits and was essentially a one-time use, the possession coins could be exchanged for skills from previously possessed individuals or saved for the next time he summoned a powerful character.
"Shunpo, 50 Million."
After scanning old man Yamamoto's attribute panel again, Rojen's eyes flickered, and he silently recited in his heart.
"Exchange."
This near-teleportation skill was something he could use, similar to the Marines' Rokushiki technique Soru, but even more refined.
The Shinigami's signature Shunpo skill was naturally powerful beyond words.
In an instant, Rojen's mind shook, and with the experience gained from being possessed by old man Yamamoto, he instantly mastered all the information about Shunpo.
"Whoosh!"
His body trembled slightly, and the next moment, Rojen's feet left the bow of the ship. Upon closer inspection, one could see that he was floating just an inch above the ground, standing steadily in the void, completely defying gravity.
"Whoosh!"
His figure flickered again, returning to his original position.
If one wasn't paying attention, they wouldn't even realize Rojen had moved.
"Compared to the speed of a spirit body, there's still some gap, but it's already quite good. After all, the weight of a physical body is much heavier than that of a soul."
When old man Yamamoto possessed him, his physique was forcibly transformed into that of a Shinigami. At that time, his strength and speed were enough to go head-to-head with Kizaru, a Pika Pika no Mi (Glint-Glint Fruit) Devil Fruit user. That speed was unimaginable.
With the weight of a physical body, air resistance increased, but the power of Shunpo remained formidable. The system's infusion and old man Yamamoto's experience allowed Rojen to master Shunpo in an instant.
Next, his gaze turned to the individuals he had previously possessed.
Before, due to the lack of possession coins, some powerful abilities or skills were impossible to exchange. But this time, he had plenty of coins to spare.
"Uchiha Itachi!"
Naturally, Rojen's eyes settled on this individual.
"Sharingan, 50 Million possession coins!"
"Tsukuyomi, 30 Million."
"Fire Style (system ninjutsu), 23 Million."
"Chakra Collection Jutsu, 10 Million."
"Genjutsu, 20 Million."
These were things he had looked at before. Back then, the terrifying prices had left him dumbfounded, and he had given up on these expensive items.
But now, Rojen's eyes began to gleam.
"The Sharingan relies entirely on mental energy, while ninjutsu..."
He frowned slightly. Ninjutsu required chakra to perform, and chakra was a type of energy within the body. However, this energy wasn't something that could be trained haphazardly.
His body had already been trained in Internal Energy and a Positive mental state, making chakra unsuitable for him.
In other words, he had to abandon ninjutsu.
Shaking his head, Rojen didn't feel regret. Training Internal Energy to a certain stage could even lead to training the true essence and immortality. That was far safer than the dangerous profession of a Ninja.
"Exchange the Sharingan."
Of course, he hadn't forgotten the powerful bloodline of the Uchiha Clan.
"Sharingan exchange successful."
The system's cold voice rang out almost as soon as he finished speaking, and Rojen's expression changed drastically.
Pain, an excruciating pain, surged from his eyes, causing his entire body to tremble uncontrollably. Scarlet threads suddenly appeared on his eyes, cheering and leaping, fiercely rushing into his eyes. From a distance, it looked as if two scarlet flames had ignited in his eyes.
This intense pain lasted for about two minutes before it turned to a chilling sensation. This coolness made Rojen feel as if his thoughts had become much clearer.
Touching his eyes, he slowly opened them.
As he gazed at the world again, everything seemed much clearer than before. Distances within a kilometer could be easily magnified or minimized with his vision.
In the seawater, fish leaped out, and as they broke the surface, the splashes of water were vividly clear to him. He could even see the slight dirt on the scales of the fish.
"Did all of this happen after the exchange of bloodline?"
After carefully experimenting for a while, a glimmer of understanding flashed in Rojen's eyes. The skills exchanged through the system's possession coins were not like martial arts manuals that could be learned directly; they merely exchanged the bloodline.
In other words, Rojen now possessed the talent of the Sharingan, but it had yet to awaken. His eyes remained the same with black pupils, and he did not feel any transformation into the Sharingan.
"That's fine; with Itachi's experience and tactics, I have memorized a lot, and developing the changes of the Sharingan and awakening it won't be difficult for me."
"Next, I will exchange for Tsukuyomi!"
Since he had acquired the Sharingan, Rojen naturally wouldn't let go of this powerful technique. Even if he hadn't transformed his eyes into the Mangekyō Sharingan yet, it was only a matter of time.
Quickly, as thoughts flowed through his mind, he completely mastered Tsukuyomi.
These skills were not like martial arts manuals; even though he had the talent of a martial arts genius, learning them was somewhat complex, resembling innate skills that were quite mysterious.
After searching through the attributes of the various individuals he had previously possessed, Rojen selectively exchanged for some useful skills before finally stopping.
After about half an hour of tinkering, Rojen felt an overwhelming sense of fullness in his mind.
It was as if he had eaten his fill and could no longer consume anything.
He had exchanged for Shunpo, the Sharingan, and various unique skills, which had temporarily satisfied him to the point where he could not take in more.
"So it turns out that martial study and the path to becoming stronger is just like eating; one can get full and even overstuffed!"
A realization dawned on Rojen.
His mind was now filled with a hodgepodge of martial studies, skills, and more, making it slowly impossible to absorb anything further.
Only by fully digesting these things could he begin the next step of absorption.
