In a flash, eight years passed by.
"Haha, I've succeeded!"
Jian Wushuang opened his eyes and there was a gold thunderbolt flashing past his eyes. He had shut himself in the cave mansion for eight years.
He had finally reached Level Three of the Divine Yin Thunder Secret Skill.
At the first level of the skill, he could produce the most ordinary black thunderbolts.
At Level Two, they turned scarlet.
And now, at Level Three of the skill, he could produce gold thunderbolts.
They contained extremely ferocious power which was at least 10 times more than that of the Scarlet Thunderbolts produced at Level Two of the skill.
"When this Secret Skill reached Level Two, it had little impact on my overall strength. Now that it has reached Level Three, it'll help increase the power of my swordsmanships once I learn to combine both together. My overall power could even reach a new level!" he thought.
