In fact, many Immortal Kings were silently cursing Lu Xuan. Given the strength that Lu Xuan displayed, it shouldn't be an easy task for even the Imperial Emperor to take him down.
What was even more terrifying was that this wasn't the end point of Lu Xuan's strength. According to the strength that Lu Xuan displayed, it was very possible for him to become an emperor within a thousand years.
A thousand years was an unimaginable distance for mortals who lived for a short period of time. However, for Immortal Kings who could easily live over a million years, it was only a short period of time, it was roughly the same concept as a mortal who had lived for a month.
"Once he becomes an emperor, I'm afraid the entire structure of the heaven realm will change!" An Immortal King said with a sigh.
