I can't remember this manhwa

Hi guys, I’m trying to find a manhwa I read before, but my reading list from the past few years is gone.

The story has a regressor MC. He has a brother who awakens a butcher-type or bloodthirsty skill and goes crazy when fighting. There’s also a comrade who is a corrupted monk.

The brother’s son becomes a future catastrophe (like a demon). There’s also an old landlady who becomes strong and has insane knife skills when cooking.

I also remember a scene where the MC invites a comrade to join them while that person was about to join another guild.

That’s all I can remember, and I haven’t been able to find it.
