However, with his ability at that time, it was obviously impossible, so Isshin had been planning for a long time.
Until 20 years ago, when Isshin went to Rukun Street to perform a mission, he happened to meet a member of the Exterminator who hated the Shinigami.
Their appearance made Isshin directly make up his mind. Since his strength was too weak, it was better to gather them.
It just so happened that there was such a group of people now, and he could use their mentality to help him achieve his goal.
So Isshin began his method. He often went back to Rukun Street to gather those who hated the Shinigami and gathered them together.
As the force grew bigger and bigger, more and more members joined, and the strength of the people who joined became stronger and stronger.
Isshin Shiba led them and came up with a huge plan to let those with high aptitudes enter Nightmare Soul Society.
He helped those who couldn't come in, providing them with cultivation methods and fighting skills.
As time passed, the Exterminator became stronger and stronger, and Isshin's desire grew bigger and bigger.
At first, he just wanted to revive his family, but later, he directly abandoned this idea because his goal became bigger.
He wanted to lead Soul Society, not only to revive the Shiba Family, but also to make the Shiba Family the royal family of Soul Society.
However, he had underestimated Nightmare Soul Society's strength. He said that he had managed to get a captain-level character to help him.
There were also captains in his force, but after all, Nightmare Soul Society was Nightmare Soul Society. With thousands of years of heritage, it wasn't something that could be easily shaken.
Moreover, as the leader of Nightmare Soul Society, Yamamoto Genryu Shigetsune didn't activate his Bankai until he defeated Isshin Shiba.
This proved that Yamamoto's strength was unfathomable, and he could completely suppress Isshin.
Isshin's ambition was directly shattered by Yamamoto's Katana, and he was facing the fate of death.
After being hit by Yamamoto's Katana, Isshin was now standing on his last breath.
Because of Isshin's defeat, the people who belonged to the Exterminator directly fell into a panic. Without a leader, they didn't know what to do.
Miyazaki Zuichi, who had been fighting with Juushirou Ukitake before, also chose to retreat when he saw that Isshin was about to be defeated.
He knew that if he continued to stay, he might really be left behind. At that time, what awaited him would be an endless hell.
He was a smart person and immediately chose to escape, although Head Captain Yamamoto and Ukitake Juushirou could stop him.
After all, Zuoichi Miyazaki had contributed a lot to Nightmare Soul Society, and he didn't really want to fight.
Since he posed no threat to Nightmare Soul Society, there was no need to kill him. Letting Miyazaki Zuoichi go was the best decision.
As for the Death Gods in the chaos, almost all of them were subdued, and only a few managed to escape.
The war started by Isshin also ended with his death, and Nightmare Soul Society returned to its peaceful state.
Although half of the buildings in Nightmare Soul Society had been destroyed, it was fortunate that they were all made of spiritual droplets, so it wasn't that troublesome to repair them.
The Nightmare Soul Society was fully responsible for the destruction of the Drifting Soul Street due to the previous battle and repaired everything.
After nearly a month, Soul Society was restored to its former appearance, as if it hadn't experienced a war at all.
Although Isshin's behavior had a negative impact on most people, his behavior also made Nightmare Soul Society reflect on themselves.
Indeed, the difference between life in Nightmare Soul Society and Nightmare Soul Society was too big, and this matter had to be taken seriously.
Due to this incident, Room 46 also held a meeting to discuss the renovation of Drifting Soul Street.
The areas at the back were generally in a state of chaos, but with the participation of Nightmare Soul Society, the chaos was gradually dispelled.
It was replaced by order, a well-ordered order. Although a lot of force was involved in this, it was unavoidable.
It was absolutely impossible to reconstruct such an area without using force, but it was all for the sake of developing in a good way.
As for Kirito, who didn't play a big role in this war, he was quite anxious now.
He wanted to improve his strength, because strength was too important. If he was strong enough, he wouldn't be so powerless in the war.
The first thing Kirito needed to do was to learn the scroll that the Arsenal System rewarded him this time. It recorded an extremely powerful Lightning Release technique.
This technique was called Lightning Release Kirin, and as the name suggests, it can release a Kirin beast to attack.
This Ninjutsu was extremely powerful, and it could be said that it was Kirito's strongest move so far.
After that, Kirito would have to unlock his Bankai, although he still didn't know how to do it.
However, he could ask the other captains, after all, they had experience. However, Kirito didn't get to see Soi Fon's Bankai, which he was looking forward to.
After that, he went to Soi Fon's captain to ask for the secret of Bankai, but he only got one sentence from her.
Fools can't learn Bankai.
This sentence made Kirito very angry, but he couldn't argue with Soi Fon's captain.
This was because he couldn't beat her, and if he argued with her, he wouldn't gain anything. Instead, he would be beaten up.
Fortunately, when Kirito was in a bad mood, he had Makoto Hikari and Lucia to accompany him. The two sisters were the lively type.
After all, which girl at this age wasn't naive? With the two of them around, Kirito's depression was nothing.
Speaking of Makoto Hikari, her talent in Dao Restoration wasn't just for show. When Kirito was seriously injured in the battle, it was Makoto Hikari who healed him.
However, Kirito's condition wasn't very good that day. His wound looked terrible, and Makoto Hikari was so distressed that she couldn't stop crying.
Lucia was also crying silently at the side. No matter how the others tried to persuade them, the two girls couldn't stop crying.
She treated Kirito's wound while crying, and it only took less than half an hour. After all, Kirito was cut several times.
Moreover, the wounds that Makoto Hikari treated didn't leave a single scar, as if Kirito wasn't injured at all.
Kirito was very happy about this. First, he was the same as before. Second, he was happy that Makoto Hikari had grown.
After so many years together, their relationship had become even closer. Kirito really seemed to have become their brother.
