Please recommend a novel with a cold-blooded male lead.

Requirements:1. Male Lead
2. No female protagonist (one at most)
3. The male protagonist must be cold and cold-blooded from beginning to end.
4. No Ambiguity
5. It's best if it's a foreign world (Magic Battle Energy World) text.
6, End
7, I want a long one
There's been a shortage of books recently. I want to see what other cold-blooded novels I haven't read. The more answers, the better, because I have read many cold-blooded novels... Satisfied with the points!

Answer 1

I recommend 'Propose 33 Times: Young Master Lu, You're Under Arrest!' The male lead, Lu Jinbei, was ruthless and cold. He would only show a different side in front of his wife, Shi Huanyang. I hope you like my recommendation.😗
