The Nascent Soul Tree Demon once said that it had locked this space, but Feng Jun and True Immortal Yi Jue didn't take it seriously.
How shall we put it? Space locking sounds terrifying, but the key is to see the degree of the lock.
An absolute space lock is out of the question; under great power, survival is impossible, but on Kunhao, it's not possible as the plane doesn't allow it.
Therefore, the space locked by the Nascent Soul Tree Demon is merely to prevent some Teleportation Talismans or Transmission Arrays, to prevent others from escaping, and might not even withstand advanced Prohibition Breaking Talismans.
If someone walked into White Pebble Beach on foot, it's quite normal. There might be a slight feeling of obstruction, but it's not severe. However, trying to enter by teleportation, flight, or Flying Boat is impossible.
