When Kana came this time, he brought three bottles of bloodline medicine to Chen Heng. These three bottles of medicine were initially intended for Chen Heng to use for a long period.
According to Jameson, these three bottles of medicine were enough for Chen Heng to digest for several years, which was calculated according to a normal person's conditions.
One's bloodline was connected to his origin. It was not something that could be easily shaken. Hence, any slight change could negatively affect the person as a whole. Countless people in this world had died directly from the bloodline change.
It was impossible for someone like Chen Heng to be alive after consuming three bottles of bloodline medicine in one go. Most people would directly die or turn into monsters. Hence, it would be very difficult for him to maintain his human form.
