Well my Absolute favourite uknonw recommendations would be
Survival story of a Sword king in another world and Reincarnation of veteran soldier (both of them superb in my opinion although some don't like Sword king)
And one of the best stories I have read so far: It starts with a mountain (it takes 70 or so chapters to have the MC establish himself and stuff but da** after that its just peak, only downside is the kinda poor art although its not that bad and recently the Tls have dropped it so now some MTL guy is working on it but he is getting better sooooo.... also thats like 700+ chapters into the story so yeah)
I can go on and on about it starts with a mountain cause its so beautifully peak story and it has such deep plots, revealing schemes or character that where foreshadowed over 200 chapters ago, the world feels alive with countless factions doing stuff and every character is just so well made.
