Wang Xiaoyi found the feeling he had in the Dead Spirit Volcano. A new line of information appeared on Wang Xiaoyi's information panel: Heavenly Lightning Resistance!

At this moment, after a month of training, Wang Xiaoyi's resistance to heavenly lightning had reached 100,000 points. Just like when he was in the fire-attribute spiritual spring, Wang Xiaoyi no longer felt any discomfort from the heavenly lightning. On the contrary, he looked relaxed and carefree, and one could even see a hint of enjoyment between his brows.

"If I didn't need to rely on your Heavenly Lightning to break through my cultivation level, I would have already mocked you!" Wang Xiaoyi thought to himself.

Wang Xiaoyi intended to use the heavenly lightning of the Nine Heavens Yinglong to temper himself, so he would occasionally pretend to be seriously injured and about to die!

"Ah!" A terrible groan came from Wang Xiaoyi's mouth!

"You filthy worm, once I get out of here, I'll make you wish you were dead!" A vicious curse echoed from the thunder.

"I'll kill him soon!" Jiutian Yinglong was panting heavily, looking completely exhausted.

This is only possible because of a peerless genius like Jiutian Yinglong. If it were any other dragon, they would have stopped long ago. No one has such a talent to release heavenly lightning for so long.

Even a peerless genius like Jiutian Yinglong was now at his wit's end. However, Jiutian Yinglong was a dragon with a strong will, and his pride was the only belief that kept him going.

"Soon, very soon, we will succeed..." Jiutian Yinglong encouraged himself.
