Dimensional Instance Explanation

"What?" Kong Rong could not fathom that what they were dealing with was a dungeon instance rather than a barrier.

"That is the theory that I have and It fulfilled all the conditions when I think about it. Tell me, a barrier is supposed to have one particular property and perhaps two, correct? But if you think about it, there is no way for an anti magic and anti chi barrier to be placed in the very same place considering that they have many conditions to meet." Jin explained.

"If you do not create an anti magic barrier with chi, the only way to do so is to put magical inscriptions and with the barrier that size, there is no way the terrorists would be able to do so without getting notice with stringent checks. Especially if you said VIPs are there, your men would have swept the place a few times thoroughly including any weakness in the Expo centre or underground tunnels."
