I'm generally not a slice of life type of guy, which this is with supernatural added to it. But I find this plot quite interesting. Before I know it I had already read all the chapters that had come out. I hope more updates will be coming soon. :)
For anyone who wants to read a VERY similar manga, try RE:Monster
A guy gets reincarnated as a goblin. Also becomes OP though through his intelligence and past experiences. Becomes leader of his goblin clan. Others join, the community advances, etc.
For once a main character that doesn't try to hide his past badassery of the past, but instead people not believing him. A far more realistic portrayal than "I will hide it intentionally and make use of my badass skills/knowledge of the past." :)
Lol the amount of times he claims to be Ye Qiu w/o anyone believing him is too many to count in the novel, so hilarious b/c his actions don't match up with their godly image of him.
I wish I could read this manwha any further, but I just can't. I've only read until just after the tournament but I just can't like the protagonist. He's just so...passive and emotionless. The artist drawing him only gives him like 2 facial expressions. (neutral pretty boy or slightly smiling) He passively watches as someone gets his ass kicked (the great sage) then suddenly when the sage gets fatally wounded he suddenly becomes...enraged I guess? (his face didn't show any expressions so hard to tell.) He insists on not killing someone even though that person has already been completely lost to darkness and evil and has killed dozens of other people just before. I mean, just...ugh. =/
Plus I'm now noticing that the manwha was apparently discontinued as it isn't updated any more...
