Frozen Warrior - Chapter 23

If you kidnap little girls, is it not fair for your daughter to be kidnapped?
What goes around – comes around. Sorry for not feeling sorry.
Karma be like:  
On another topic.
This story become kinda meh.
In first chapters, our protag been described as unstoppable warrior from era long past. He achieved his power via martial arts, with the only person that could rival him being the evil guy.
Amazing premise: two warriors from lost era, tearing world apart and no one being able to stop them.
Now tho? Everyone and their dog, can just get a shot of whatever magic bs in those ampules. And somehow, instead of dying horribly from not knowing how to manipulate ther own life energy (ki), become on pair with warriors from old era. Screw martial arts, who needs them, right?

Another issue: apparently entire murim appeared and all of them decided to send their kids to same school.
Like protag, 800 years later, on a planet with 7 billion people, somehow found a girl that descends from his previous charge. Ok, chances of that literally 1 in 7 billion, but fine.
That girl somehow become friend (enemy?) of a classmate, whose father is from murim. Okay, coincidences happen. Also, in the same class there is class president who can use ki… Small world, right? What a the chances of that to happen, I wonder.  
Oh wait, I forgot, that dude in glasses, that protag met in chapter 1 here too!  
Another thing that I seen a lot in this story. One minute, theres no one. Another second – 10 people apper from thin air… from behind the protagonist… where there a wall with no entrances. 
Heck, in last chapter: Yoon (illusion girl), who can hold her own against protag, should have soloed those guys. Instead, one fraim- no one behind her. Another fraim– she being held by two guys.
One second – there no one standing before the leader, another second – there a two guys holding weapons. I guess, ki gives people from our era ability to teleport and keep weapons where sun doesnt shine? 
Dont get me wrong, stuff like that happens in every second anime/manga. Im simply pissed because, this story could have done a lot better than this, the possibility was there.
