There was more than one Immortal King here, let alone an Immortal Emperor in the void.
He could completely imagine what kind of terrifying ending would await him if he interfered earlier.
Most probably, he wouldn't be able to escape death. Even the Immortal Kings of the Nangong Family wouldn't dare to protect him.
No one could bear the consequences of angering an Immortal Emperor. Even the Nangong Family was no exception.
To Immortal Emperor, a clan with only one Immortal King wasn't more vital than an ant. Once they were tempted, they would be dead for sure.
He immediately sat down and acted like an ostrich, as though he didn't say anything at all.
At this moment, in the Battle Ring, Lu Xuan only looked at Nangong Wuyin in front of him and didn't say anything. He also didn't announce that he had won.
