Solving the case is a little bitter, but my sister is super sweet

Lin Xuan was reborn.

No system, no cheats, no golden fingers.

But God gave him a perverted body.

The gears of fate also began to turn at this moment.

…

Mu Qingtian: Brother-in-law, do you have a dream?

Lin Xuan: Yes, I want to show off.

Mu Qingtian: …

Lin Xuan: Showing off is a desire for dignity, a fantasy of reality, and a right to yearn for. What is the difference between not showing off and being a salted fish… Oh, my wife, why are you hitting me?

Mu Qingyan: Vulgar.

Lin Xuan: Yes, as a scholar, this is called showing off in front of others.

Mu Qingyan: …

From then on, Lin Xuan went further and further on the criminal investigation road of reasoning and solving cases!
