Chapter 35: The Purpose of the Kyuubi Rebellion
"Sir, why did Obito attack Konoha?"
"The reason is simple. Obito just wants to weaken Konoha and maintain the balance of the entire ninja world." Lux answered.
"Weaken Konoha?"
Minato was a little confused. After the Third Great Ninja War ended, there was no winner.
All the major villages suffered heavy losses, and Konoha also had to bear the consequences.
Lux briefly explained to both Minato.
After the Third Great Ninja War:
Sunagakure Village's Third Kazekage disappeared, and civil war broke out, which greatly damaged its vitality and almost destroyed it. Rasa, the Fourth Kazekage, was barely able to restore the village and could not attack.
Kirigakure Village's Third Mizukage, Bijuu lost control, the Seven Ninja Swordsmen collapsed, the Blood Mist policy killed a large number of ninjas, and some of the remaining elite Anbu were also killed by Obito, and they were also unable to attack.
Iwagakure Village, in the Battle of Kannabi Bridge, Minato destroyed fifty Iwagakure elites, and 10,000 Iwagakure troops forcibly killed the Third Raikage, with the most casualties.
Kumogakure Village's Third Raikage died in battle, and there were also many casualties.
