Although the strength of the first elder was formidable, how could he possibly fight against everyone in the sect at once?
Initially, the sect members intended to imprison him while investigating the events of the past years and punishing him accordingly. However, he resisted and attempted to kill everyone in a bid to escape. As a result, all the sect leaders and patriarchs decided to eliminate him.
His crimes were far too severe to be overlooked or forgiven. He had killed his own disciples and siblings and destroyed his ancestors in his pursuit of wealth and fame. Such acts instilled terror in everyone regarding his cruelty, especially when considering his involvement in sordid affairs that harmed teenagers.
