Ahhhh this manhwa was just...disappointing. The art was AMAZING, the plot had a lot of offer, and the concept was really intriguing. The execution, however, was atrocious.
Getting through the beginning was honestly hard because the amount of fanservice(?) and lechery was absolutely cringeworthy and disgusting. Once the MC was effectively yeeted into the plot, things started getting interesting as more of the world is revealed, cool shit goes down, and badass characters duke it out. Classic, top notch.
I continued to read because despite the MC getting a lot of (mildly justified) flack, I was really interested in the MC's master's powers/abilities, learning about the world, and the endeavors of the side characters. It almost seems like every character arc/plot point except the MC's was well executed. There were a few loose ends/cans of worms that were opened and then just...forgotten about. Things kept happening at such a pace that certain ideas, concepts, and plot points were never fully developed. This led to things feeling rushed (MC's development of skills/abilities) and "unrealistic", if that's a thing in this manhwa.
Also, if you're reading scans then avoid the comments section. Those fools are absolutely feral.
Pros:
Art is incredible
The world building is intriguing
Side characters have a degree of development
Art style does a great job of illustrating fight scenes/cool moments
Cons:
MC has little/no character development
MC's master was horny to the point of derailing the plot
The master/student training was sorely underdeveloped
Shit just kept happening before the previous plot point could be fully developed
tl;dr - I don't feel like I wasted my time reading this, but I'm not going to waste my time reading it again. The art and a handful of god points 'save' it.
