Passing the Formation

The Celestial King in black had harbored no positive feelings toward Ling Han. Everyone knew this.

Now, Ling Han had appeared here, while the Celestial King in black was nowhere to be seen. What did this signify?

The Celestial King in black had been… killed?

Gasp!

If this were true, the information that it revealed was far too terrifying.

Firstly, it was extremely difficult for Celestial Kings to kill fellow Celestial Kings. This was recognized by everyone. As long as the gap in cultivation level wasn't large, a Celestial King wouldn't be able to stop another Celestial King from fleeing.

Secondly, how long had passed? Yet, a Celestial King had already been killed?

To kill the Celestial King in black with such ease, just how overwhelming did Ling Han's battle prowess need to be? He had killed him in such a short amount of time, and he had more so stopped him from fleeing?
