The situation in Great Sum deteriorated very quickly. In less than a month, voices emerged suggesting Seigniors wanted to visit Sum Emperor in the Capital city.
Clear-sighted people could all see that those Seigniors were not only expanding their armies but also stockpiling food and forage. They weren't planning to visit Sum Emperor; they were clearly aiming to compete for that position.
In fact, most Seigniors temporarily harbored no intentions of becoming Emperor themselves, especially those whose blood ties to the royal family were separated by several generations. They were well aware that lacking legitimacy would hinder their aspirations to become Emperor.
Therefore, a portion of the Seigniors proactively contacted the princes in Capital city, secretly forming collaborative relationships with them. In their fight for succession, the princes agreed to the Seigniors' terms, further complicating Great Sum's already chaotic situation.
