Why would Ancestor Ji Kong want to break the seal on the Sealed Land?
It brings him no benefit; it's not something Master would do. There's only one possibility: this matter must be the doing of the Golden-Winged Peng Bird. The Golden-Winged Peng Bird is deeply bound to Ancestor Ji Kong, so the Lingbao Sect is inevitably affected. The Divine Beast's renown served as an external deterrent, making the Great Sects wary and causing them to act with more caution. The Golden-Winged Peng Bird breaking the Bizarre Seal signifies that the Lingbao Sect has broken the seal of the Sealed Eastern Land! The borrowed power has turned into a blade stabbing at the Lingbao Sect. The Lingbao Sect can't shoulder such a huge blame.
"Why would the Golden-Winged Peng Bird do this?"
It couldn't have sensed the aura of… a Divine Beast in the Sealed Eastern Land, could it?!
