Obsessed with immortality, and highly manipulative, lets Changsheng follow you around or rest on your body since he knows the snake adores you more than anything...He is very clever, kind when he needs to be, genuinely feels bad for you, and is worried that your condition might get worse...Once he gets close to you, he clings to you like crazy and pumps you full of healing and medicinal herbs...Refuses to let you die so will lace your food and drinks so you get constant doses of healing herbs...
