Su Qianqian had never seen the Taotie.
According to Guo Degang, one left too early, the other returned too late, making it impossible for them to greet each other.
Su Qianqian was merely the Residual Soul of the Taotie, appearing only when provoked.
Thus, she had no knowledge of how the Taotie descended upon the world, nor did she know that after its reincarnation, the altar at the entrance of the Divine Hall had lost its power until the Taotie's death and re-entry into the cycle of rebirth when the altar would regain its divinity once more.
Su Qianqian knew nothing of this, even assuming amid her delirium from blood loss that the altar's curse had taken effect, driving her more into madness.
"I want you all dead, everyone must die!"
After dealing with the Purple Gold Zombie, Zhao Yi and the shrunken Purple Gold Divine Dragon arrived at the entrance of the Divine Hall, just in time to see Su Qianqian in a mental breakdown, shouting and screaming like a madwoman.
