Tsunade, who was managing both outer conversations and inner thoughts, was taken aback by the realization.
Katsuya Sage remarked,
"What a terrifying individual. Most gifted shinobi like Orochimaru, or those from powerful clans, are either born with exceptional spiritual strength, allowing them to master ninjutsu faster, or with potent physical talent that lets them easily use their clan's bloodline limits or secret technique with ease."
"But Ron... Ron's spiritual strength, in terms of quantity, has already surpassed nearly every shadow-level ninja. Only a few in history with Yin-type bloodline limits, like those with Mangekyō Sharingan, could compare to him. And even they would struggle to match him."
"It seems," Katsuya added, "that his spiritual quality, which truly determines the power and force of chakra, mastery, and most importantly, ninja rank, has only recently advanced into the shadow level. But at this rate, even that will soon reach its peak."
Kurama gave a slow, solemn nod, "Yes. During this period, both the quantity and quality of his spiritual strength will continue rising. In fact, soon his spiritual quantity will already be approaching your grandfather's at this young age. What an astonishing being."
Of course, all these had a reason; despite not having undergone his physical growth spurt yet, Ron had already attained shadow-level physical strength. This was thanks to his diligent training in Lightning Chakra Mode, his bloodline as a descendant of the Third Raikage, and the cutting-edge resources at his disposal, like healing chambers and gravity-based training.
Most importantly, Ron's innate immense spiritual strength further enhanced his body by drawing out its potential and strengthening it to match his spirit due to the chakra connecting them, resulting from mutual growth and affecting each other. With chakra acting as the bridge between body and mind, his mental strength allowed him to become stronger and maximize the effectiveness of his physical form.
Over the years, Ron had absorbed knowledge at a staggering pace. His godly intellect, coupled with his sharp mind, had enabled him to study and internalize almost all chakra-related materials in Kumogakure as well as countless scrolls and texts gathered from across the world by the village and the Daimyo. His spiritual development resembled that of someone who had lived for centuries like a sage who had seen nearly everything, which was a form of growth on top of his immensely naturally born spiritual strength. If normal civilian ninjas start at 1 in terms of spirit when they are born and experience exponential growth until reaching adulthood, thus going from 1 to 2 to 4 to 10 to 20, then Ron started at 100, or even more, and has grown at an even faster rate, due to his experience and knowledge.
At the age of 7, almost reaching 8, His spiritual quantity had already reached the same level as his father, the current Third Raikage, a super-shadow-level shinobi. His spiritual quality, however, had only recently broken through and will stop at the peak of the shadow level. His current breakthrough came while flying through the skies using the Sky Dance Technique, searching for the site to build the Storm Ascension Tower. During those flights, Ron had felt something change profoundly. He had finally felt alive in a different sense, truly present in the world. That mental shift had sparked his spiritual transformation, allowing him to break through to the shadow level.
