Synopsis

The protagonist learns that his gacha pulls are influenced by his location and the historical significance of the place, not just the character's perceived strength. This realization leads him to a hidden dungeon in Hwaseong, revealed by a diamond card summon of Jin Jeongdo. The dungeon was built by Jeong Yak Yong with a complex series of brick locations serving as a key. Upon entering the dungeon, the protagonist must pass academic and martial arts tests to obtain treasures.
