"So, because the corpse of this second young master appeared in many places at the same time, they created this 'rule'?" Shi Jiu said.
The rule is to stay away from the waters at night. Even on day, they shouldn't stay near it for too long.
"This world is said to be supernatural." Huo Ling spoke. "So, it's because of this?" he said and looked at Yi Bing.
"I think." Yi Bing said. "We didn't notice anything unusual that could be a supernatural when we arrived, until we find out this." he explained.
They nodded in agreement. The classification and sub-classification of the worlds are based on two things: time, and the energy, respectively. A world classified as normal or special is based on time. It is a Normal World if it is an ancient or modern world. If it is beyond, then it becomes a Special World. As to how beyond the time it is… it depends on the technology of the world.
