Ah Qing's insults made the dean really furious but there was nothing he could do.
He wasn't that intellectual and smart dean anymore. He became more stubborn and more afraid of death the older he got.
He didn't want to die, so he decided to work together with Chang Qing to think of a way for people from the Celestial World to come down.
Since the Celestial Gate was closed and the key was nowhere to be found, he would let one person ascend and open up the Celestial and Mortal Pathway so that people from the Celestial World could seize this chance and head down.
Such an outcome made Ah Qing's life really dangerous. If people charged in, they would incur the wrath of the lightning tribulation. Of course, Celestials could block it but what about Ah Qing?
No one cared whether she lived or died.
