A forensic doctor traveled to the Ming dynasty and became an apprentice of a coroner. He had a poor family, a mother, and a wife who followed the three obediences and four virtues but was barren. Apart from dealing with various murder cases, he also had to take on the responsibility of continuing the family line under the pressure of the clan. He could only try his best to earn money and take a concubine. At this time, however, strange things began to happen one after another.
