It is the slowest story progression I have seen in my entire life.
Revenge? You'll be dust before we get even close to thinking about revenge?
The protagonist already started being almost the strongest, so after the childhood arc, there's almost no serious struggle, he just crushes most opponents, and it's not even interesting as like other "OP" character titles.
When the author could settle a plotline in just one or two chapters, it gets dragged for like 10 chapters.
The artwork is not the greatest but decent. Overall story is just mediocre, some people may like it, but for me, I didn't like it.
And about characters, [Spoilers Ahead]...
Excluding the step mother, who is just intended to be villain, Do you know who are the real villains in MC's life?
It's three people, his father, the namgoong patriarch and his daughter.
His father is the worst father a child could ever have, just because your "loved" wife died, you pushed the only child of that same "loved" wife to brink of death.
Next, The "sworn brother" namgoong patriarch, He just left the MC fully knowing that he is being neglected and abused, MC's father told him himself, plus after MC returns home with his daughter, did he not go to meet him? Just a single look and anyone could tell MC's state. But he just took the so called "successor" and left turning blind eye to everything.
Last but not least, oh so mighty and beautiful lady namgoong. She saw MC's state herself, and figured about everything about his abuse from a glance and promised to "protect him", and what did she do? Fed MC, and gave the stepmother a glare. If she is so intelligent as portrayed, did she not ever mention about these to her father
brother, or even anyone? Nah, she just left. She forgot about her promise even after growing up.
On a second thought, it was for the better, MC found the mirror, became powerful. Left home and found his True Family.
