A rare gem. This manhua has the right amount of plot, MC is trying to be lowkey but forced by other "protagonists" to act every time. MC's cultivation and smithing skill progression doesn't feel forced, but naturally grows as the story goes on. No Deus ex Machina kind of plot devices, no plot holes in the world building, no common-sense destroying cheat system, no copy-pasted world-settings, just perfect. MC is not the most powerful out there, but he's invincible in his realm. And what's more, MC is not one of those pretentious and show-off type of guy, so I like him.
One of the only manhua which doesn't force the stereotype "only MC can have beautiful girls". MC has a childhood sweetheart which the ship already sailing, and a couple of girls which has a crush on MC. The fact that this doesn't have harem or romance tags bothers me, is it only a mangadex tag fault or is it a foreshadowing of the failure of their relationship? I'm not sure but I'd hate it if their relationship fail.
This manhua have the right amount of "fan service", not too much that you'll think the girls are btches, but enough to give some spices to the story.
As of chapter 38 I'd rate it 9.5/10
Hope translator continue their excellent job so far, cheers.
