the progress

after unsealing the protection barrier, Kaoru walked to the training ground where the Konoha twelve sparring.

after two years of heavy training, their power and specialty increased tremendously.

first, Guy's team Kaoru taught them several martial arts from his world, he also removed Neji's bird cage, and for Tenten, he taught her about weapon techniques and metallurgy plus blacksmithing, he even asked Shirou to prepare some swords that he knew for Tenten's training.

Kaoru even imagined that someday Tenten would wear full golden armor and walk proudly while calling everyone that fought her a 'mongrel'.

for Neji and Lee, since Kaoru only focused on training them in martial arts like Wingchun, Muai Thay, and many more, their Taijutsu became more lethal, especially for Neji who combined a fast movement of Wingchun with Hyuga's gentle palm technique.

second, Kurenai's team, Kaoru focused on teaching them about detection, espionage, and assassination, since they had what they needed. this time Kaoru has to acknowledge this team has a frightening detection ability, Hinata has her byakugan, Kiba's nose is very sensitive, and Shino's insects could be his eyes and ears.

he told them to improve their control over their own power and ability however, he never thought that Hinata had a Yandere side to her, she didn't bat her eyes when she almost decapitated Kaoru's clone in their sparring and Kaoru let down his guard for a moment after taunting her about Naruto.

and when he saw her smile at that time, Kaoru had a cold sweat on his back, her smile reminded him of several Yandere girls, like a certain pink-haired killer Yuno, red-haired schoolgirl Hiyama Akane, and many more.

after that Kaoru makes a reminder in his head that he should never threaten Hinata with Naruto.

third is Kakashi's team, after Naruto trained with his Mother, followed by Sasuke who also trained by Orochimaru and unlocked a snake sage mode, Sakura learned under Tsunade about medical knowledge, and his hypothesis about Sakura also proved true, Sakura may act unlikeable but, after received a beating from Ino, she started to change, and she is not entirely useless.

in the Canon, Sakura could use Tsunade's hundred seals just in a few years, when Shizune who could be called a small genius who could follow Tsunade's lesson still can't perform that Jutsu.

especially when one of the requirements for Hundred Seals is to constantly supply a chakra toward the seal and it cannot be used before the accumulated chakra reaches a certain amount which is marked by a diamond-shape tattoo appearing on the place where the user stores their chakra.

with a small curiosity, Kaoru and Orochimaru asked for a blood sample from Sakura and their discovery could shock the entire Konoha, Sakura actually has a connection with the Senju and the Uzumaki clan, and both of them theorize that Sakura's grandparents or great-grandparents are a part of the outer member of the Senju clan or the Uzumaki clan, however, her small amount of chakra is what makes it strange, since no matter how thin a the bloodline, the Senju, Uchiha, Hyuga, and Uzumaki will always have dominant effect.

it was proven by Tayuya, that even though her Uzumaki bloodline is too thin to detect, her red hair and the massive amount of Chakra have become a testament to her origin.

in the Boruto, Sakura also could be called the strongest before those aliens or androids appear, she could solo Uchiha Shin easily after all.

because of this Kaoru and Orochimaru have one more schedule on their already full schedules, and that is to unearth the reason for Haruno Sakura's strange physiology.

last is Kaoru's own team, after teaching them about Haki, Kaoru let them work on it, and with Shikamaru's intelligence, they could combine Haki with their Jutsu.

whit Busoshoku Shikamaru could solidify his shadow better and started to create animals, weapons, and even some monsters from his shadow unfortunately he doesn't have enough Chakra to spam shadow soldiers like Sung Jin Woo.

and for Chouji, with Chifuyu's special training menu, Kaoru's torture, and Shirou's nutritious meals, what Kaoru could say about Chouji is the second coming of Douglas Bullet.

Chouji has a terrifying affinity with Busoshoku Haki to the point that only the top genius on One Piece could be compared with him.

however what shocked Kaoru the most was Ino's growth, her use of Kenbunshoku and Shintenshin created a new technique that could be called pseudo-Haoshoku Haki, with Shintenshin Ino's fake Hao is more deadly since she could destroy her opponents mind.

and the difference in physical strength was useless since her technique relied on her mind strength or soul power.

when he arrived there, Kaoru could see that the training ground had been destroyed by their sparring, and he also felt pity for Kakashi if he wanted to try to spar with his student.

he chooses to spectate how the Konoha twelve spar, and as he predicted, Shikamaru's team is too overpowering, their crowd control is too perfect, to the point that forcing both Naruto and Sasuke to use their sage mode.

"it seems that I need to train their mind, just one Jutsu from Ino was enough to incapacitate all of them except for Naruto and Sasuke."

Kaoru already makes a plan for his next torture session, and the Konoha twelve who already wake up from Ino's attack suddenly feel shivers on their back.

----

in the village of sand, a lone shadow floats in the sky, everyone looks at that shadow confusedly, and Garaa who takes the seat of Kazekage after the death of his father tries to approach the shadow however, in a moment he can hear an icy voice.

"Shinra Tensei!"

after that, a terrifying pushing force appears and keeps pushing the entire village without caring about anyone or anything in its path.

just in a second, the former sand village is now nothing but a ruin, and Garaa the Kazekage also missing, however, the sands suddenly move and several figures emerge from within.

a blonde woman in black stood up to try to find her people, even though there was still some terror in her eyes and her trembling body already told everyone about her condition, she still had a duty to make sure everyone was safe.

"Temari!"

when she wandered around, she heard someone call her name and she immediately looked at the person, he also wore a full black attire and he was accompanied by several people.

that person was her brother Kankuro, and the people around him were a jounin or chunin that he could save in time.

"Kankuro, what happened? I saw a strange shadow in the sky, and when Garaa wanted to approach it everything turned upside down, I even got separated from Maki and Matsuri"

Temari still can't think about what happened since it was too sudden and she demands an explanation from her brother who she believes was near her other brother Garaa before Garaa chose to approach that thing.

"What I could think of, was that shadow was a person, and the one who destroyed the entire village also that guy actually before losing my consciousness I also saw several people attacking Garaa right after that power hit us, and when I woke up, Garaa is missing, together with those attackers"

Temari who heard that explanation could only fall to the ground.

"Imp- impossible, how is that possible for one person to destroy a shinobi village in an instant." Temari kept mumbling in her denial, and she suddenly got an idea.

"Let's ask for help from Konoha, after that conflict and both villages lost their leader, the sand village asked for a ceasefire and started to propose a peace treaty and an alliance between Konoha and Suna!" Temari told Kankuro about her plan while pleading hoping that her brother would accept it.
