What started off as just venting, transformed into a life-and-death battle that almost destroyed half the sect grounds. The grand elder got defeated in the end, however, the sect master chose to spare his life.
That same night, that grand elder left along with almost half of the elders along with their personal disciples. Depleting the sect's foundation further. The sect master didn't stop them since the grand elder had insisted he'd rather die than remain and those who went with him, shared the same sentiments.
Even with all that had happened, the sect master still didn't punish his grandson but instead decided to make him an envoy of the sect. That position guaranteed he would be spending most of his time outside of the sect which would be a welcomed relief to the rest of the sect members who remained.
