Feeling the shaking all around him, Musk was puzzled, but he did not stay anymore after all he had already taken benefits and he did not want to waste his energy in his place. Jumping into the pool of water, he began to descend before he started to head the way he came. But before he had gone further he felt the shaking intensifying.
Since he was underwater, he could see the icebergs crack slightly, this made him more aware of the power of this situation. Even though Musk could be barely hurt by the collapse, he did not want to experience it, as only a fool would let such a huge chunk of an iceberg collapse on them. He kept descending to avoid it, and at the same time, he felt the water temperature drop drastically the slower he moved. This had him more shocked. Basically, the situation in this place should not be like this unless there is some other treasure at the very bottom of the water.
