Nangong Wuyin didn't hold back at all. He knew that Lu Xuan was different from any legendary geniuses he had fought before from the fight earlier.
To him, the names of those legendary geniuses might sound scary, but they were totally on a different level.
He was the reincarnation of an Immortal King and was destined to become an Immortal King again. The probability of those legendary geniuses becoming Immortal Kings was very low. They weren't on the same level at all.
However, Lu Xuan was different. He was an existence that could even threaten him!
This spear was pushed to the extreme by his Law Of Wind. It was speedy and swept out like a storm.
"Swish!"
This spear actually passed through Lu Xuan's body. Under the circumstances that no one expected, it actually passed through Lu Xuan's body in an instant.
It only left behind a streak of lightning!
