Thunder Emperor Stone

After this stone entered his hand, it seemed to have sensed the power of lightning in Zhou Han's body. It immediately seemed to resonate and boiled violently.

For a moment, lightning flashed, and the wreaking energy surged.

"It's indeed good stuff. After absorbing the energy inside, my lightning control will improve at lightning speed!"

"Gou Tuo, you're indeed lucky!"

Zhou Han's eyes revealed a satisfied expression. If he remembered correctly, this stone was an item dropped by Gou Tuo after killing a six-star Supreme-grade Thunder Swallowing Beast.

A mere Supreme-grade demonic beast could drop a Pseudo Sovereign-grade item. Therefore, ordinary people really could not compare to this luck.

This was also the reason why Zhou Han sighed.

"Hehe! As long as it's useful to you, Boss, it can't be better!" Gou Tuo rubbed his head and smiled.

As long as Zhou Han improved because of this, he would naturally obtain a lot of rewards.
