Ninja, as the name suggests, is a group of practitioners who use ninjutsu as their main fighting method. The origin of ninja can be traced back to the Warring States Period a long time ago.
At first, ninjas used organizations or families as units to plunder other organizations and families, plundering their resources (such as chakra fruits, ninja tools, psychic beasts) and territories. Later, organizations and organizations, families and families formed alliances and became villages, and villages started fighting with villages.
Later, villages formed an alliance with each other to form city-states, and city-states started fighting with each other. Finally, city-states combined with city-states to form countries. Countries continued to fight for resources and territory for a long time.
In addition, political differences have arisen within many countries, leading to a situation where the country is about to disintegrate. In some countries, the ministers even want to take over the military and political affairs of the country on behalf of the monarch. Everyone knows their arrogance!
(Readers, this novel is a complete tribute to Naruto and the youth lost in those years!)
