This can probably also be considered a different kind of fear: afraid that brothers suffer hardship, yet afraid they pave their own way in luxury.
Those top-tier cultivators speak so honorably, claiming that once everyone enters the Spiritual Domain, it's all based on individual ability...
However, in reality, in Zhou Dawe's plan, these cultivators were merely meant to be used to exhaust the Originators' strength, serving as expendables to pave the way forward.
But now it seems that the strength of these expendables has exceeded all expectations, as they're about to push all the way to the opponent's Crystal Tower.
By then, their contributions, their sacrifices, their scheming...
Would all fall behind and only entitle them to the smaller share?
