In the Pyramid World, if a cataclysm-level boss creature or a disaster-level boss creature were to appear,
Tang Xian couldn't imagine the tragedy that would ensue if both creatures rioted.
Even a plant that couldn't move was enough to turn an entire red soil forest from woodland into an abyss. If the white snake made it to the human realm, it might be capable of even more horrific deeds.
As for the cataclysm-level boss of the Qing JiuYu...
Human civilization describes the historical blank text as a great cataclysm.
Even if Qing JiuYu were to get angry, it might not cause an extinction event of the great cataclysm level.
But it could probably set civilization back a few hundred years.
Tang Xian was not afraid to try; Tang Xiaojiu was the most terrifying creature he had ever smuggled.
But Tang Xiaojiu was very young and had not yet harbored hatred for humanity.
It was harder to say with Qing JiuYu and Bai Mansheng.
