Introduction to the work "A Son-in-Law Is Like a Knife"
When Shen Yan woke up, he was kneeling on the green brick floor of a century-old ancestral hall.
He traveled through time. He became the son-in-law of the Cheng family, a prominent family in Suzhou. Both his parents were dead and he was powerless. Even the order in which he dropped his chopsticks during meals depended on people's faces. The father-in-law handed over a piece of sea trade deed with a smile, and his tone was as gentle as if he was inviting him to tea - if he signed it, he would be the scapegoat for the whole family to smuggle banned goods; if he didn't sign it, the Cheng family would have hundreds of rules waiting for him.
This is the Cheng family. Very elegant. Grow flowers, hide paintings, and follow rules. Everyone spoke tenderly and hid their knives tightly. And Shen Yan, the adopted son-in-law, was nothing but air in the eyes of everyone - until one day, the old man in the ancestral hall who had been silent for many years knocked on the ground with his cane and said something.
"From today onwards, Qin Mo will enter the ancestral hall to discuss matters."
The sheep were thrown into the crocodile pond. But no one knew that this adopted son-in-law, who was regarded as nothing, was no longer the cowardly and useless Qin Mo. He has a power called the "Memory Palace" in his mind - a draft in the wastebasket, a knot on a prayer bead, the heat of a bowl of ginseng soup, and an unintentional gossip are all clues in his eyes, and they can be put together into a chess game.
What he wants to find out is not just who is smuggling banned goods. What's more, the "accidental boat capsizing" murder case three years ago—who was the person in charge of the fourth house of the Cheng family and his late father-in-law who was killed in the river under the Duseng Bridge?
…
The deepest knife is hidden in the gentle words. And Shen Yan wants to return those knives one by one.
Pretty good plot
