I'm having the exact same problem as you, especialy now that the LoM is completed. Pretty dissapointing but I couldnt find anything that is quite on the same level as this, but there are a few that come close, at least writing qualitywise:

God of Cooking (first that came to my mind for some reason ), The Novel's Extra (the first half or so), Release that Witch (for the most part, especially the first half), Sevens (probably beeing a bit too subjective here but i had great feelings about the novel during the process of reading).

A little late in replying, but hope it helps you in finding something that will be your cup of tea, and if you do find a novel at the same level as LoM thats not on the list, please do recommend it to me.

@Lei TIan The Legendary Mechanic is in my top 3. Power scaling, world using, and awesome MC interactions with the whole cast of characters is imo LoTM level. It's more lighthearted and comical but imo it's up there with the best. Other than that, the Beginning After the End is pretty well done.

I liked A Will Eternal,but I've put on hold reading ISSTH and Rengade Immortal a while back, when I run out of things I'm currently reading I'll probbably start re-reading those two because I remmember they were quite interesting... and aside from that, as you can see I am more of a I Eeat Tomatoes fan

btw glad you like the list.
