Saint Bow glanced around again and said quietly, "That chaotic stretch of Cubic Distance cannot be entered, because it is merging with the surrounding Cubic Distance."
"From the very beginning, that place was the birthplace of the Human Nine Fortresses Civilization. As Main Dao used various Fishing Civilizations to attack the Nine Fortresses, that stretch of Cubic Distance gradually changed from ordered to chaotic. Perhaps the destruction across that area was too severe, so the Masters sealed it off. Even the Master Clan was forbidden from entering. They could only send The Unknown in to hunt down the Nine Fortresses' descendants and the remaining forces of the Main Dao of Death."
"Some time ago, that area gradually began returning to normal. The power of Main Dao descended, intending to make the area like the surrounding Cubic Distance. This takes time. During the process, the power of Main Dao must completely fill and orderly cover that stretch of Cubic Distance. Unless you're protected by the power of Main Dao, anyone who enters will be in for trouble."
"At best, they'll suffer the destructive effects of the chaotic power of Main Dao. At worst, even death would be a mercy. They might be lost in time or erased by karma."
"In short, you can't enter until that chaotic stretch of Cubic Distance has completely merged with the surrounding area."
