yang Jian transformations disease

The following day, everyone who drank the infected water was struck down by the plague. Within a couple of days, smoke no longer rose from the chimneys, nobody walked in the streets, and the air was full of cries and groans. No one could avoid the plague, not even the disciples in the prime minister's mansion. Only two men remained unaffected - Nezha, who was reincarnated from lotus flowers and Yang Jian, who was able to do transformations.
