Chapter 255: Chapter 255 - 255. Rune Diagram

The monsters inside were indeed as mentioned, all of them were basic monsters with levels between twenty to 25. All of the monsters were the same type, Lesser Earth Elemental. They resembled the Small Rock Golem which Jack had fought before in his hunting quest. However, unlike the Small Rock Golem, these Lesser Earth Elementals weren't impervious to physical attacks. Their outer skin was more similar to dirt than rock, hence it was not too difficult to break through their defenses with physical weapons. Their movements were rather slow, and they could only execute melee attacks, making them an excellent target for accumulating experience points. Jack scored more than just experience points. He also got loots from these Lesser Earth Elementals which the cadets were ignoring, mostly coins and materials. There were also trophy items called Elemental Powder, he should be able to exchange them for a fair amount of coin in the Hunters Association. He happily stored all the loots. He also received souls from each of the Lesser Earth Elemental slain. The higher their level, the more souls they gave. Unlike yesterday, Jack didn't just stay passive and let the cadets do all the work. He would still get the same amount of experience even if he just stayed at the back, but he would not get any proficiency points if he didn't use his skills. So he put all his skills into use against the Lesser Earth Elementals, even when a normal hit was already sufficient. His addiction to increase his skills' grade from the Training Ground had followed him here. The proficiency gained however was at a normal pace. The monsters were mowed down expeditiously with Jack's help. As they ventured deeper, Jack also noticed that at several intervals, there was some kind of large glowing rune carved on the cave walls. His interest was piqued. He asked Peniel in his mind, 'What are those runes on the wall that I keep on seeing?' "That was part of a rune diagram," she replied. 'Rune diagram? Like the one we saw on the walls of Duke Alfredo's estate when we were investigating the missing painting quest?' "Yeah, this is another one of those." 'What's the one in this cave for?' "I haven't seen all parts of the diagram to be sure, but it was most likely got to do with how this cave was made into a training place for the cadets. It controls the growth of the monsters to a certain grade and range of levels. It also increases the spawning rate of new monsters after the previous ones were vanquished." Ah, no wonder there seemed to be no end to these Lesser Earth Elementals, Jack thought.
