In the next few months, rimuru continued training tsunade in all things he knew. From medical ninjutsu, basic ninjutsu, advance ninjutsu to basic cultivation knowledge.
He also forced tsunade to exercise her body for a good foundation or so he heard.
As for rimuru himself, he has increased the 20% in the template to 30%.
It seems that the progress is extremely slow.
Though it is because he only drinks alcohol to increase the template.
Other than that, various movements in the ninja world has happened.
Since the second great ninja war has started, rimuru advised his granduncle tobirama to always be alert since he remembered that tobirama died because of the ambush of the ginkaku and kinkaku brothers.
He hoped that this early information will allow his granduncle to avoid his fate and even if things go wrong, the worst that could happen is him stepping in and showing his strength.
Many Konoha ninjas have stopped going on mission as its war time.
The border of the land of fire has been strengthened due to the start of the war with higher than normal defense.
War preparations have already been started and money from the Konohagakure treasury has begun to be spent.
Various teams of Anbus has been sent on highly classified missions while only a few were left in Konohagakure on patrols.
Maybe it's due to the signs of an upcoming war but the atmosphere in Konoha is duller than usual.
The reality of war is disheartening for the Konoha villagers who has seen it.
Although there is still some lively atmosphere here and there, but it isn't much compared to before.
…
Konohagakure War Conference
The room is filled with various patriarchs from the big ninja clans and some famous yet canonically unknown ninjas.
They all had a very serious expression at the main meeting.
Although there was a final plan meeting a few months ago but this time war is just ahead, and they need to discuss it again as planning ahead and planning at a moment is very different.
Tobirama sat on a chair at the center, showing that he has the highest authority in the room.
With his usual cold face, he said: "a recent news came from the border guards. A thousand sunagakure ninjas had been spotted at the borders."
Hearing the sudden news, the patriarch in the room were very surprised.
They thought that it'll at least take a year or two for the other villages to prepare materials for war.
The money and supplies needed for a war is huge and the time interval between the first great ninja war and the second great ninja war is too short.
How can they recover so quickly?
Seeing their doubts, tobirama nodded.
"Yes, it is all true. Sunagakure has been spotted near the borders. Recently, the spies in Iwagakure reported that ninjas from other villages have gathered and it seems that there wasn't any conflict or grudge between the ninjas."
The room fell in a dead silence.
After the first great ninja war ended, many families whether they be from noble ninja families to the lowest civilian ninja families or civilians in general have lost their family members.
The loss family members bring hatred or grudges against those who killed them.
This is often the true reason why the so-called "cycle of pain" doesn't end or so what Pain said.
However, time will heal pain, but that time isn't now.
It isn't even a decade since the war has ended and now the villages have united in the truest sense?
The patriarchs from various prestigious and powerful clans all had ugly faces.
If what the hokage said was true then Konohagakure would be in a dire position.
The amount of experts in the enemy side is too great for Konoha to take care of by itself.
Usually Konohagakure would be able to handle four great villages if the villages have bad relationships with each other thereby causing internal disputes.
Konoha then could take advantage of that internal disputes and win a major battle or two and go back to negotiate with the villages.
A "security vulnerability" to a solid victory, so to speak.
If that security vulnerability is patched then Konoha would need another "security vulnerability" to take advantage of but that'll take time.
At this moment, The Nara clan head who is known as the think tank and a calm and intelligent person has broken his calm expression into a rather serious one.
The first to speak was the Nara clan head who expressed his doubt.
"How did the four great ninja villages unite together?"
Tobirama held a piece of paper that he prepared which entails the reports from the spies in the four villages.
"The spies from their respective villages reported that a super genius suddenly arose. These super geniuses are said to be the successor to their own respective villages so they would have huge influence in their village. These super genius cooperated with each other leading to this situation."
Handing a copy of the report to everyone present, tobirama continued.
"Iwagakure has a super genius that specialize in what seems to be an extreme scorch style ninjutsu that the sunagakure village used to have."
"Kumogakure super genius specialize in taijutsu. The most notable thing is his huge mace and his impenetrable-like skin."
"The super genius in sunagakure has an enhanced version of the magnet style of the third kazekage."
"Lastly, Kirigakure's super genius has an enhanced version of ice style. Being able to turn into ice allowing himself to avoid physical attacks and release ice with high degree of freedom."
"All this super genius have a minimal strength of kage."
When tobirama's last words fell, the whole room once again fell into a silence.
Extreme scorch style, impenetrable defense, extreme magnet style, extreme ice style.
All these ninjutsu or blood succession limit are very powerful.
Hearing that the super genius now have kage-level strength brought even greater shock to everyone in the room because with their strong abilities, their danger level increase accordingly.
Meaning their combat effectiveness isn't just a regular kage-level but around peak of kage-level.
Fighting them on the battlefield is very difficult.
God knows how many ninjas have to be sacrificed to bring one of them down.
In addition to the untold unity of the villages, the powerful super geniuses brought the final nail in the coffin.
As early as tobirama read this report, his arrogance and contempt for the ninjas of the four great villages has been put away.
If his arrogance and contempt still remain even when hearing this report then he might as well abdicate from the hokage seat.
As for the rest of the big families like the Uchiha, Hyuga, Senju, and etc.
They now started discussing countermeasures against these super geniuses.
As the discussion gradually heated up, a loud sound of the door opening was suddenly heard.
Everyone turned their attention to see who has the guts to open the door to a high-level meeting conference.
Their eyes fell on a familiar figure.
Senju Rimuru.
Two words flashed past their minds but just as they was about to ask why he's here, Rimuru said.
"Granduncle! I heard you saying something about a super genius. I could solve them if you want."
Everyone looked at rimuru confused.
How could you who just stepped into the kage-level handle 5 peak kage-level ninjas?
R*tarded?
As for tobirama the granduncle that rimuru is referring to, he looked at rimuru as if looking at a dumb person.
His eyes seems to be saying 'How are you going to deal with them?'.
Seeing the doubts of everyone in the room, Rimuru revealed a mysterious smile.
"I have cultivated the way of a sage."
Most people in the room had black lines on their head, showing their irritation and impatience.
"Ahem, I have mastered sage mode."
His incoherent words were finally coherent, bringing a certain light in tobirama and everyone else's eyes.
Hope appeared in everyone's eyes.
Sage mode is very well-known to everyone in the room as they have heard or seen the first hokage's sage mode.
So, everyone knows how powerful of a boost it gives to anyone who is a kage-level ninja.
Everyone looked at rimuru with shinning eyes, some of the higher ones motioned their eyes at tobirama, seemingly want him to say everyone's request.
Tobirama seeing this, finally said: "Rimuru, could you show us your sage mode?"
"Right here?" asked rimuru.
Tobirama nodded at him and motioned him to start right now.
All gazes focused on rimuru while everyone released their chakra perception, seemingly wanting to perceive what changes will happen when using sage mode.
At this moment, Rimuru closed his eyes for a second before re-opening it, revealing his golden pupils which seemed to glow.
Other than his pupils glowing, there was no other change on his body which disappointed everyone.
They thought that his sage mode has failed because even the sage mode of hashirama gave visible marks such as red markings on the face.
One particular ninja, although disappointed, still asked rimuru.
"Did it succeed?"
A tiny bit of hope still showed in his eyes when looking at rimuru, seemingly want rimuru to say "yes".
His hope wasn't betrayed because rimuru nodded.
Pointing to his golden pupils which has a faint glow, he explained: "My sage mode is a bit different from grandfather. The only visible difference would be my glowing eyes but rest assured, my strength has been increased by multiple folds so I could still hold down 5 kages."
After his explanation was finished, everyone was a bit skeptical at this but still trusted rimuru due to the reputation of the first hokage and the second hokage.
The meeting continued on for another while before it ended with the final plan a bit revised.
Rimuru would confront 5 super geniuses at the level of kage while tobirama would support multiple battlefields and take out the kage-level ninjas besides the 5 super geniuses.
