[Manhwa need. Please help]

I want a manhwa in which the MC has these characteristics:

1. talks less

2. Overpowered

3. Elegant(every action needs to be elegant)

4. Coldhearted

The manhwa can be of any type, except for harem, romantic, or new.

For reference, the MC of [Legend of the Nothern Blade] was somewhat like this.

Please help me find a manhwa. I have been reading a lot of manhwas but so far most of the MCs are too energetic.
