When Keitarou are seeing the fight between Lee and Naruto, he remember the time he meet a very strong enemies in the summer of his third years in high school.
Flashback
The enemies are just a couple of years older than him but his enemies are already at the peak of Great Grandmaster Realm. He fought with young Great Grandmaster Realm cultivator when Keitarou are training Shinmei school sword style under the head of Aoyama Clan Eishun.
But at that time, the main Residence of the Aoyama clan attacked by the Yakuza Clan, the Luo Cha clan who was the worshipper of fire and cloud demon god.
The Luo Cha Clan want to eradicate one of the biggest white sect in Japan, The Shinmei Sect. Under the order of their young leader Luo Cha clan who have a lot of Grandmaster warrior realm as their member are giving the Shinmei Sect a big surprised they never seen before.
Shinmei Sect was a Sect of Cultivator specialized in Excorcism of a demon and youkai. So a lot of the sect member are almost never have an experience in fighting another human cultivator so they are all having a hard time to beat the cultivator from Luo Cha.
At that time Keitarou also just reach the early stage of Grandmaster Realm so his cultivation at that level is still not stable so Eishun is forbid him to fight.
***
Fire and Cloud demon god or Shibumi, it was the name of the leader of Luo Cha the strongest yakuza group in Japan. Not even the Japan goverment want to challenge the Luo Cha, because the leader of Luo Cha, Shibumi are a very strong cultivator who was at the peak of Great Grandmaster Realm. He was almost undefeated by using the final stratum of Yin Jin Jing one war tatoo.
Yi Jin Jing the cultivation tehnique from Shaolin who made Shibumi almost invincible, are very hard to learn and not even old demon god, Shibumi father can reach the one war tatoo level like Shibumi.
Because Shibumi are reaching the highest peak of Kung Fu that really hard to reach by a lot of cultivator, right now a cultivator who can fight to draw with him are really rare. And right now Shibumi are fighting the leader of Shinmei sword style school Eishun Aoyama one of the strongest sword cultivator in Japan.
"Fight me to stalemate like this only using a peak of Shinmei style sword cultivation tehnique you are really worthy to be called as Japan sword saint Eishun Aoyama. But how long you can fight me? My Ki was never ran out because I can absorb Ki from the air but you did not have any abilities to restore your Ki like me! Now did you have a way to beat me?"
The leader of Luo Cha, Shibumi is very arrogant because he already reach the highest step of Kung Fu. But Eishun who also at the same level of him still look calm even though his stamina is already half gone.
***
"You are to arrogant Shibumi, even though you are much more younger than me and also at the peak of Great Grandmaster Realm like me. Your chance to defeat me is zero! I simply have more experience than you! And even though my Ki is limited but my Ki reserve is better than you!"
Eishun was a war veteran in the magic wars on Mundus Magicus a warrior who was on par with a monster like Jack Rakan, Albiero Imma and also Nagi Springfield. There is no way he would lose in fight againts a younger generation like Shibumi.
Eishun are moving so fast using quick move and then slashing his katana to Shibumi using one of Shinmei style killing moves specialized made to kill a human.
Ordinary sword slash cannot cut Shibumi body that protected by the energies from Yin Jin Jing. But Eishun slash are reinforce using Ki, plus his katana was not ordinary katana. It was a magical weapon.
So the Ki shield that protected, Shibumi body are broken and Shibumi green oni mask are cut in half along with his faces. Shibumi only save because he was fast enough to avoiding his body cut into two parts by Eishun.
"Arrgh you bastard! How that sword could be strong enough to cut my body!"
A lot of blood was coming out from the wound on Shibumi faces. He doing his best to stop the bleeding by trying to close his wound by burning it using Ki.
***
"You are weaker than me, Shibumi! Go home to your dad the old demon god! Atleast as a fighter he can give me a good fight even though he was one level weaker than me!"
Eishun hand was strangling Shibumi neck, right now the young Fire cloud demon god are almost dead. His body are full of bruises, cut and also a blood. Shibumi even though have a power on par with Eishun, but his Cultivation at the peak of Great Grandmaster Realm was still not stable. So the power he can utilized at the peak of Great Grandmaster Realm are far from perfect.
And even though both Eishun and Shibumi are at the peak of Great Grandmaster Realm, but Eishun cultivation level was almost reach the level Unity Nature realm.
So no matter how strong Shibumi is right now, he was weaker than Eishun even if their cultivation level is the same.
"You are brutal, evil and did not have sense of honor like your father! You supposed to be feel ashamed with your behaviour, you only tarnished the name of Luo Cha."
Eishun then stabbed his katana to Shibumi stomach to destroy Shibumi dantian and meridian. So Shibumi would not try to attack another big martial arts faction in Japan.
"Because I have a deep a respect to your dad then I would not kill you. But I would make you cannot use your kung fu anymore. Try your best to find a way to heal your dantian, sadly even if your dantian is healed you will never as strong as before!"
***
Because of Eishun effort, Shibumi are succed being chased out from the Aoyama Clan main Residence. A lot people are die in the hand of Shibumi and his subordinate. But Luo Cha also lost as lot of their Grandmaster realm warrior in the fight between Shinmei school sect and Luo Cha. After the fight againts Shibumi, Eishun vomitting a lot of blood from his mouth.
He maybe defeating Shibumi, but the prices he must to pay to defeat the Peak Great Grandmaster Realm when his half step to Unity With Nature is unstable are really big. Eishun almost lost all of his Cultivation progress because the fight againts Shibumi.
Thankfully Eishun inner wound are not too bad, so with enough rest he will be okay and back to normal.
For Keitarou, Shibumi who only two or three years older than him are insanely talented. Not even him who was the most talented member in Urashima Clan History can reach the peak of Great Grandmaster Realm even if he was training seriously. For Keitarou training seriously for three years would only making him reach the peak of Grandmaster Realm.
End of flashback.
'According to Eishun-san right now Shibumi is focusing all of his attention to find a way to cure his damaged Dantian and meridian so he was searching for the mysterious Silkworm manual that can be used to patch a damage dantian and meridian. Well I already having it because it was one of the bargain sale item on Chat Group shop. The manual are easy to learn so no wonder it was very cheap! It only worth one hundred shop point!'
