Chapter 301:
The Battle of Kannabi Bridge was the most critical confrontation between Konoha and Iwa.
The bridge served as the primary supply line for the Iwa forces. Without it, they couldn't maintain their army, forcing them to retreat.
Recognizing this, Konoha devised a plan to destroy the bridge and cripple the enemy's supply chain.
The task was entrusted to Namikaze Minato and his team—Kakashi, Obito, and Rin.
While Minato distracted the enemy head-on, the other three infiltrated and successfully destroyed the bridge. However, during the mission, Obito was severely injured while saving Rin, crushed beneath a falling boulder. Half of his body was destroyed, and he was ultimately rescued by Uchiha Madara.
Orochimaru remembered this series of events vividly.
Some might wonder why, knowing all this, Orochimaru prioritized dealing with Kumo before Iwa. Wouldn't addressing Iwa earlier have prevented these events from unfolding?
Orochimaru had considered that possibility.
If he had confronted the Iwa forces first, there was a chance these events might not have occurred. But he concluded that the likelihood of change wasn't significant.
