In Mu Yue's impression, the Third Great Ninja War had been utter chaos. Everyone attacked each other, then joined forces to gang up on Konoha.
Kumogakure attacked Sunagakure and Konoha, while Iwagakure attacked Konoha and simultaneously stabbed Kumogakure in the back. After Sunagakure repelled Kumogakure and saw everyone else attacking Konoha, it joined in as well.
The mist ninja, who rarely took part in Ninja World Wars, saw how lively things were and thought, Wouldn't I look out of place if I didn't join? So they began attacking Konoha too.
The Kazekage disappeared, so let's attack Konoha.
Those Kumogakure brutes are too detestable, so let's attack Konoha.
In short, whenever they did not know who to fight, attacking Konoha was the answer.
That was more or less what Konoha went through during the Third Great Ninja War.
If a fierce hero had not appeared out of nowhere in the form of Minato Namikaze, the Yellow Flash, the outcome of the Third Great Ninja War would have been hard to predict.
"Ten thousand Iwagakure ninja surrounded the Third Raikage. Yahiko was forced to his death by Danzo and Hanzo, causing Nagato to fall to darkness. Uchiha Madara manipulated Obito into falling to darkness. Might Duy opened the Gate of Death and turned the Seven Ninja Swordsmen into the Three Lucky Treasures..."
Mu Yue recalled the major events of the Third Great Ninja War and could only sigh at how dangerous the ninja world was.
If things followed the original story, Nohara Rin would soon throw herself onto Kakashi's Lightning Cutter, Obito would immediately turn into a deranged madman after falling to darkness, and Might Guy's father would open the Gate of Death to protect Might Guy before ultimately sacrificing himself.
Shisui alone seemed not to have lost anything during the Third
