Xing Ling was a 3-Xuan immortal.

That was a level that would be challenging for Wu Yu to defeat.

However, the Primordial Immortal Empire's dragon king was obviously intent on testing Wu Yu and measuring the depth of his strength. He was also trying to guess the identity of the immortal backing Wu Yu, the immortal who had given Wu Yu a powerful legacy.

Wu Yu's single fatal attack just now was insufficient for the dragon king to discern the depths of Wu Yu's strength or the identity of this immortal.

Actually, the Interstellar Domain Dragon King had sensed that something was amiss. However, it was too late. His son had volunteered himself for battle, and the Primordial Immortal Empire's dragon king had also announced the battle. So there was nothing much that he could do.

"Xing Ling, do fight seriously. And give it your all. Do not be complacent and relax your guard," he reminded.

"Father, do not worry. I know what to do," Xing Ling said as he descended and landed before Wu Yu.

The two of them stared at each other. The mystical dragons become excited again. Many dragon monarchs watched the battle attentively. 

Because this battle concerned the pride of the mystical dragons of the Primordial Immortal Empire!

It was obvious that Wu Yu was young and had trained for less than 1,000 years!

Whereas Xing Ling had trained for over 100,000 years.

This difference simply proved that Wu Yu was no ordinary man. There had to be a reason why...
