"Whoosh!"
"Buzz buzz!"
The Demon Monarch's cold voice fell, and with a sweep of his sword, a massive black Energy Slash, stretching tens of thousands of feet, charged towards Gu Chenfeng with the power to destroy all things. The space within hundreds of thousands of feet trembled violently.
Although the Demon Monarch hadn't used his full strength, the power of this sword was still terrifying.
The Demon Evil Power of the Demon Monarch was far stronger than that of the Penglai Island Master.
"The power of this sword is extremely frightening," Gu Chenfeng frowned and said, "Even though I possess Ancient Ice Attribute Spiritual Power, at this moment, I still feel a hint of threat."
Gu Chenfeng had the protection of Ancient Divine Power and incredibly strong Ancient Ice Attribute Spiritual Power, yet the power of the Demon Monarch's sword could still make Gu Chenfeng feel threatened, which shows how powerful this sword was.
