Key Insights

  • Shenlang is publicly known as the dumbest, most promiscuous, and least educated young man in the country, a reputation that hides the fact that a genius has reincarnated into his body. This false image lets him move and gather information without anyone suspecting his true intelligence.
  • The protagonist's previous life was as an extremely attractive and famous chemist who became a doctor after an accident disfigured his face, permanently changing how people treated him despite his unchanged talent and skill.
  • The reincarnation was triggered when an American bomb came flying while he was helping patients, and his dying wish was simply to be reborn handsome, which came true in Shenlang's astonishingly good-looking body.
  • Shenlang's X-ray vision came from his lab's X-ray machine fusing with him during time travel, letting him see through objects, identify items accurately, and read all their technical specifications like a built-in medical scanner.
  • The X-ray vision is integrated with an actual laptop from Earth that exists in his mind, combining medical scanning with computer analysis so he can look at anything and instantly get technical data about it.
  • Su Kanshan married the original Shenlang only because she was sick and needed a husband to change her luck, then discarded him once she recovered, exposing herself with a suspicious reaction when the doctor declared him healthy.
  • The original Shenlang was so obsessed with Su Kanshan that he abandoned his own parents, who were beaten and thrown out by the Sue family's guards when his father tried to take him home after the marriage.
  • Underworld boss Tian Hang, who has hundreds of murders under his belt, was hired to bury Shenlang alive over a debt where his brother borrowed five gold coins that ballooned to 100 gold coins through compounding interest.

Questions & Answers

Q: Why does Lady Mulan want Shenlang as a fake husband?

Lady Mulan needs to be married before the Zoo family’s general arrives with a proposal, because refusing him could cost her family vital support in an upcoming war. Shenlang’s reputation as the city’s dumbest and most harmless young man makes him seem suitable, although she initially only allows him to enter the marriage competition.

Q: Who is Shenlang really behind his dumb reputation?

Shenlang is a reincarnated genius who was a famous chemist and later became a doctor after an accident disfigured his face. He now inhabits the body of a handsome man whom everyone considers the country’s dumbest, most promiscuous, and least educated young man.

Q: Why is Lady Mulan’s marriage decision so urgent?

The Zoo family’s general is arriving much earlier than expected, leaving Mulan’s family only three hours to act. Refusing the proposal could make the Zoo family withdraw its war support, while Mulan’s plan to disfigure her face would not prevent the marriage.

Q: Why does Shenlang enter Lady Mulan’s marriage competition?

Shenlang wants to get close to Lady Mulan and confidently declares that he wishes to marry her. His public reputation makes the family dismiss him as foolish, but they do not know that he is actually intelligent, informed, and cunning.

Q: How did Shenlang gain X-ray vision and a mental laptop?

The X-ray machine from his laboratory fused with him during his time travel, while his actual laptop from Earth appeared inside his mind. The two abilities work together, allowing him to see through objects, identify them, and obtain their technical specifications.

Q: Why did Su Kanshan marry the original Shenlang?

Su Kanshan was sick and needed a husband to change her luck, so the original Shenlang volunteered because he was obsessed with her. She recovered and defended him from the maids, but their marriage existed only in name and they did not behave like a couple.

Q: How is Shenlang expelled from the Sue family?

After Su Kanshan recovers, Jang Jai kisses her and announces that she is now his fiancée. He tells Shenlang that the two do not belong together and orders him to leave within an hour.

Q: Why is Shenlang ambushed and nearly buried alive?

Underworld boss Tian Hang captures Shenlang because his brother borrowed five gold coins that grew into a debt of 100 gold coins through compounding interest. Since the family cannot repay it, Tian Hang plans to bury Shenlang alive as compensation.

He begs for a job to get close to the goddess. With only three hours before a rival proposal, the family arranges a fake-marriage competition, and the idiot Shenlang confidently asks to participate.

  • Shenlang is secretly a reincarnated genius chemist and doctor from Earth, disfigured in his past life by an accident and killed by a bomb. His dying wish to be reborn handsome came true.
