I dont know if this is how literature usually is in korea but ... gd dam what the hell is this pacing and shty plot points. It flows like rapid of sewage
like the random villagers the MC ran into understood how to deal with the undying knights better than literally anyone else in this entire story, cut their limbs and head off, can't fucking walk around indiscriminately killing people if you don't have the physical ability to.
Or you could just dig pitfalls, drop the knights into them and then fill them in with rocks and dirt. Problem solved instantly.
God, such a dumb story. The entire premise is broken from the very beginning, but instead of having an ounce of clever storytelling
they'd rather do an asspull and make the MC zombie jesus.
