After the heroine was reborn, she found that she had a space pharmacopoeia that was "unique in both medicine and poison", but every time she saved someone, her lifespan was consumed. She used this ability to build her own pharmaceutical empire in Shanghai, while secretly investigating the truth about the annihilation of her family in her previous life. The biggest twist is that the warlord commander who seems to be a villain is actually her lover who died in her previous life by blocking the gun. In this life, the two are on opposite sides, falling in love and killing each other.
