Eigo had also collected some survival jutsu from his clan library. Basically it mostly stealth and escape techniques. But in order to achieve proficiency he had to try manipulating other elements with his mediocre chakra reserve he can't master any technique.
He was introduced by his mother Hashina kokuen the current leader of kokuen clan to a specific instructor named Shadow. Shadow is the leader of the intelligence gathering unit called No names. No names are group of people gathered from various clans and villages which are either destroyed due to clan wars and village conflicts.
Shadow took Eigo to the forbidden area of the clan library. The clan library for in the head house of the clan but the forbidden area was present in a underground cemetery.
"Eigo Sama I will be teaching thinks to become a good leader for our clan. It will be hard to digest some facts but know this everything is for your own good".
Young master "what do you think about essential qualification one should have as a leader of a kokuen clan?
"
"I think strength and strategic thinking and patience" Shadow san.
Shadow was quite delighthed by Eigo words but he didn't show it in his face
Eigo sama" what you said is half right and half wrong. What you said might be applicable for a normal noble clan or a shinobi clan but we are different".
Eigo looked confused and asked shadow to explain.
Eigo sama" I will show you the details of all hidden villages dating back from warring state period".
"The kokuen clan was one of the best clan for assassination. We were called No name we did impossible missions not because we are strong because we had insights on people weakness and were they are vulnerable. We bribed, smuggled, kidnapped, poisoned even once created a plague once to wipe out a entire clan of 600 members. We were not noble we created chaos in order to stand where we are now.
Yes some things back fired like creating the plague almost destroyed our clan we rebuilt using all the chaos in this world. We are just using opportunities in those troubled world".
After saying about all that Shadow left, with Eigo thinking in the dark library with a candle.Eigo started reading the books in the library. It mostly contained intelligence and a summoning scroll.
He left the summoning scroll in the bag and started reading about history of the warring states period. He was quite curious about the warring periods as he knew nothing about them.
Apparently are not only five great hidden villages but there were numerous villages after the warring state period but things changed after the First and Second Shinobi war. The best example is the Uzumaki clan and the land of whirlphool they were feared as the fearsome people with soul jutsu even then they are destroyed.
Eigo came to a conclusion that to be alive its not about becoming the strongest kage level Shinobi. Its all about connection and authority while being cautious about the power houses in this world.
The best example is Sarutobi Hiruzen, he was hailed as the strongest kage level expert or is he. He avoids conflicts at most point.
After sorting out were to focus, Eigo went to Shadow for instructions
Shadow though Eigo the breathing technique and chakra suppression technique.
The breathing technique and chakra suppression techniques are all originally physical skills like holding under water and wrapping ourselves under the surrounding nature.
Hashina had informed Shadow about the assassination attempt on the young master but he was quite shocked with the progress he had with the feeble chakra reserve and corroded blood volume in Eigos body.
