It wasn't that Minato Namikaze was taking advantage of the situation. Forbidden ninjutsu had severe side effects, but the fact that Haze Hidden Village had been able to contend with the enemy until now proved just how powerful this kind of ninjutsu was.
One had to know that along the various defensive lines, the areas defended by small villages had all suffered defeats. Some villages had not even managed to withstand the first wave of attacks. Haze Hidden Village's forbidden ninjutsu possessed all sorts of formidable abilities and could greatly ease the current situation.
Minato Namikaze needed more power to help Konoha fight its enemies. Facing the powerful Dawn Hidden Village, he felt overwhelmed for the first time.
The more he learned, the more he understood how terrifying Dawn Hidden Village was. Whether in the number and quality of its shinobi or the nation's economy, Dawn Hidden Village surpassed Konoha. Moreover, because their nation had no nobles, all resources could be mobilized freely. This was completely different from the Land of Fire.
Even now, with the Fourth Shinobi World War underway, the nobles living in the Land of Fire still spent every day eating, drinking, and making merry. The Land of Fire's daimyo even felt that war was an extremely troublesome matter and wanted Konoha to make certain concessions in exchange for peace between the two sides.
The enemy charged like wolves and tigers, their war machines advancing at full force. Their own strength was inferior to the enemy's, and on top of that, they had a group of nobles dragging them down and internal power struggles. Minato Namikaze felt utterly exhausted.
Faced with this difficult situation, as the Fourth Hokage, he had to help the village overcome this crisis. Therefore, he needed to gather ninjutsu that could strengthen Konoha!
