Jiang Lan wasn't too concerned about the situation at the entrance to the Netherworld.
As long as he found the culprit, he would know what was going on.
Moreover, everything could be a smokescreen that the other party had purposely released.
The attacks outside might not necessarily be targeted at the Netherworld's entrance.
He looked up. At this moment, someone was divining the situation in the realm made by his Catoptric Deflection. There was an entrance to the Netherworld in the realm, and Jiang Lan was sitting cross-legged and cultivating in there.
As long as the other party had finished his divination, he would be able to receive some feedback from the array.
He would then be able to find the general location of his enemies.
After a while.
The voices outside had already faded away. He did not know the exact situation either. It was not the time to go out.
He would be patient and wait a little longer.
