The Hua family was supposed to be the obscure cultivators of the central plains. They were trying to figure out a way to find the heavenly water spirit for generations. More than a thousand years ago, a dozen of Hua's first ancestors followed along the Yangtze river and arrived at the Jianggendiru Glacier of the Geladaindong Peak's southeast slope. However, they failed to find the heavenly water spirit and were even attacked by the strange tadpoles.
After the strange tadpole bore into the human body, it would immediately control its host to dive back into the ice sheet. If the host were to leave the ice sheet, the host would be similar to the Kunlun disciples that Po Tu caught, such that the host would open his mouth and spat out the bug. The host would turn into a dried corpse while the strange tadpole would then look for a new host.
