The fourth level.
When Su Yu stepped into the fourth level, he felt a special feeling.
His five internal organs were like an oven!
His internal organs were burning!
Su Yu took a deep breath. On this level, he felt the power of the five elements. In the path of cultivation, it was often said that the five internal organs versus the five elements. Su Yu instantly understood that this level might be where the five internal organs and six internal organs were located!
Or to put it another way, the fourth, fifth, sixth, and third levels might be within the entire abdominal cavity. The areas where the five viscera and six bowels were located, including the area where the navel was located.
“What about the arms?”
Su Yu thought to himself. He did not seem to see his hands. If he was really stabbed into the ground, the arms might hang down. Could it be that they were also in the underground level?
Both arms had been stabbed into the death spirit world?
There was still a possibility.
