“Tenxiu brother, come here quickly! You said you’d only be out for two months at most, but you’re only just back now. You really made me wait! If you hadn’t remembered to send me stories, I would have thought you’d been enchanted by someone and forgotten all about me!”
Uchiha Tenxiu’s arrival excited Uchiha Yukino, who quickly extended her soft, small hand to motion for Uchiha Tenxiu to sit beside her. She even puffed out her pale, baby-fat cheeks, feigning dissatisfaction, as she spoke of her longing over the past few months. Her words seemed like complaints, but in reality, there was no displeasure towards Uchiha Tenxiu; her eyes held only deep yearning for him.
This made Uchiha Lingyue, who was nearby, feel a pang of jealousy, as if she had lost something, but then she quickly calmed down.
“I’m truly sorry! Yukino, it’s all my fault for not organizing the mission properly, which caused the delay!” Uchiha Tenxiu slowly sat beside Uchiha Yukino, apologizing profusely and making various promises until she was satisfied.
“Hehe, then Tenxiu brother, you have to spend more time with Yukino in the coming days, or I won’t be happy!”
At this moment, Uchiha Yukino’s large eyes sparkled like jewels, and her long, pure white, beautiful, and smooth hair cascaded over her shoulders like a waterfall, making her look like a lovely princess. Far from detracting from her beauty, it added a touch of liveliness and playfulness. Moreover, in that moment, her eyes seemed to hold only Uchiha Tenxiu.
Uchiha Tenxiu naturally understood that in this Ninja World, Uchiha Yukino was precisely the one who could maintain complete trust in him and would always obey him.
After a period of expressing their longing.
Uchiha Tenxiu also proposed the idea of a treatment.
“…In short, with this, I can extract the life energy from it and inject it into Yukino’s body to seal it. Of course, all of this must be combined with the mental strength training method I specifically customized for Yukino. These two must be done simultaneously; otherwise, a large influx of life force would instead cause the spirit to passively absorb body energy.”
“This would worsen the condition. So, wait a moment, regarding the mental strength training…”
Uchiha Tenxiu explained the principle behind this treatment, ensuring Uchiha Yukino could understand.
Uchiha Yukino, who had also learned a great deal of medical knowledge from Uchiha Tenxiu, naturally understood the profound principles contained within this entire process, as if enlightened. It was as if her current physical condition was not so much an illness as it was an overly powerful talent from her bloodline inheritance, like an unbridled wild horse, causing her spiritual energy to lose control and subsequently triggering a passive absorption of body energy to sustain its growth.
The most urgent task now was to ensure her body had ample energy to support the robust growth of her mental strength.
At the same time, during the process of mental growth, it needed to be tempered, so that this mental power could be firmly controlled. In the future, under her guidance, it would grow orderly like a babbling brook, rather than blindly overflowing like a breached dam, allowing it to run rampant.
“Do you want to invite the Clan’s physicians to assist with the treatment? If it’s just one person…” Uchiha Lingyue inquired from the side, seemingly feeling it was a bit unsafe.
“No need, I trust Tenxiu brother!” Uchiha Yukino nodded, showing no doubt about Uchiha Tenxiu’s proposed treatment plan, fully trusting him.
Seeing this, Uchiha Tenxiu took out a fragment of the greer stone and handed it to Yukino.
The life energy from an entire greer stone is too immense, and Yukino’s condition requires several courses of treatment. Therefore, this fragment will be used for the first step of the treatment for now.
“So, the key is this mental strength training method and this greer stone!” Uchiha Yukino’s eyes widened as she looked at the green fragment in Uchiha Tenxiu’s hand. Her body was filled with a faint craving, making her completely believe in the possibility of her healing.
At the same time, Uchiha Yukino’s eyes became slightly moist. So, Tenxiu brother went out this time specifically to find a treatment for my illness!
No wonder!
For this reason.
Uchiha Yukino’s heart was filled with immense emotion, followed by a wave of self-reproach for her own thoughtlessness. She inwardly vowed to repay Tenxiu brother’s care for her.
Meanwhile, Uchiha Tenxiu activated his Sharingan and imparted the so-called mental strength training method to Uchiha Yukino.
Uchiha Yukino, immersed in the genjutsu space woven by the Sharingan, gazed at the overview of the mental strength training method and was instantly shocked as if struck by lightning. She was the second young lady of the Uchiha Clan elder’s household; Uchiha Yukino was by no means a naive and ignorant simpleton. Her so-called weakness, innocence, and cuteness were merely her exclusive demeanor in front of Uchiha Tenxiu.
Having suffered from illness since childhood, Uchiha Yukino was considered incredibly strong in the eyes of others, not to mention her tireless efforts to cure her own ailments. Due to her extensive and deep understanding of how to resolve these pains, the continuously growing mental strength within her was of paramount importance.
However, no matter what, Uchiha Yukino could not find any solution, the most crucial point being her inability to control her own mental strength. This was because, in the Ninja World, there was simply no method for training mental power; one could only passively increase it through daily arduous training. Yet, precisely this most crucial aspect was something she herself could not cultivate at all. Thus, she was trapped in an insoluble dead end.
But what did she see now? It was actually a secret technique that could specifically train mental energy, outside of Chakra refinement.
Such a thing was miraculous and unheard of.
Not to mention, according to the outline of this mental training method, one could completely cultivate their mental power to an extremely refined state. Each realm division within it could possess miraculous abilities, which, when viewed across the entire Ninja World, was simply unbelievable.
If judged by Ninjutsu.
It was definitely a Forbidden Technique beyond S-rank.
Even ordinary super S-rank Forbidden Techniques couldn’t compare to this training method, because it could be reused, and the cultivation difficulty was not high. As long as one followed the cultivation path, it could be completed with consistent effort.
What did this signify?
This meant it could help Ninja break through their own restraints and limitations. It should be known that Chakra, this special energy, is actually produced by the combination of powerful mental strength and physical energy. Therefore, when a person’s mental energy increases, their Chakra’s intensity will naturally also increase accordingly.
In this way, someone who was originally at Genin level could potentially increase their strength and become a Chunin through this method; those who were originally at the Chunin stage would have the opportunity to break through further and be promoted to Jonin; and even those who were already powerful Jonin would have a certain probability of breaking through to Kage-level.
If the existence of this ability were known to the outside world, it would certainly trigger fierce competition among the various Clans.
After all, who wouldn’t want their Clan members to become stronger? And this competition would likely trigger an unimaginable war, with all factions resorting to various means to compete for this precious resource, potentially even leading to the entire Ninja World falling into complete chaos and turmoil.
And this was actually imparted to her by Uchiha Tenxiu brother. This made Uchiha Yukino fall silent. To obtain such a secret technique, who knew how much hardship and exhaustion Tenxiu brother endured to bring it forth.
“Not to mention, once this secret mental strength cultivation technique is exposed, he will surely be hunted down by the entire Ninja World.”
“Tenxiu brother must consider me the most important person to teach me such a secret technique!” Uchiha Yukino felt like she had discovered something, and her heart was filled with immense gratitude.
Compared to other Ninja in the Ninja World who treat Ninjutsu as family heirlooms, never allowing even the closest people to casually peek, Uchiha Tenxiu’s actions made the already loyal-to-death Uchiha Yukino’s love for him explode.
