The heroine's surname is Lin and her given name is Juemang. Lin Ruhai has a distant relative from the fifth service, the Lin family, the royal doctor of the capital, and a cousin of the same age and different generation as Lin Daiyu.
Lin Juemang was born in a family with medical skills. His girlfriend's name is Miao, which means he is the reincarnation of the miracle doctor Sun Simiao.
Juemang has divine power and uses the power of other people's life to irrigate a dead flower so that it will not decay for seven or forty-nine days. If you make incense from this flower and burn it, it will have the power to extend your life with this person's obsession.

It sucks people's energy to make elixirs, and can turn dead people into zombies.
This is the secret technique recorded in the Lin family's secret book - the return date. Even if one life is worth one life, some people will eventually buy it.
Maybe doctors are kind-hearted, maybe human life is shallow.
But after all, when your breath is dying, you don't care about the day or night.
