Kang-ho was surprised when he levelled up twice with just one golem, but soon his surprise turned to realization as he finally saw what was going on in the room. The room Kang-Ho was inside was filled with mana when he entered and right now it felt like all the mana had been drained. Kang-Ho became puzzled at first but he suddenly remembered something, he remembered the huge object that was floating in the air. Kang-Ho turned around to see what was going on and he realized that the thing that was floating in the air had lost all its mana suddenly.
Kang-Ho understood one thing from this, whatever that huge object was had helped him in levelling up twice after killing the goblin. As Kang-Ho was thinking about what was going on the golem slowly broke down in pieces and slowly turned into pile of clay, although the object in the air had lost all its mana it still was floating in the air.
