However, Zhu Jiuyin remained composed, his right hand slowly erecting to form a mysterious seal before his chest. Following this, streaks of azure-black light gathered in his palm, resembling meteors streaking through the night sky.

Suddenly, the endless Green Fire Demon Thunder reversed its course in an instant and then vanished into the void.

Time had flowed backward!

Zhu Jiuyin's Time Law transformed into flickering lights that scattered outward, enveloping both him and Kunpeng Ancestor.

The two of them instantly entered a different time flow rate separate from the outside world.

Under these circumstances, unless one had insight into the Time Dao, outsiders could not discern their movements.

Yu Yuan of course was an exception.

He also had a certain understanding of the Time Dao.

In his eyes, time in the region where Zhu Jiuyin and Kunpeng Ancestor were located was passing at thousands, tens of thousands times the speed, and he himself had to activate the Time Law in order to clearly see the combatant's interactions.

Kunpeng Ancestor surveyed his surroundings and upon noticing the changes in the environment, immediately activated the Beiming Palace, unleashing a surge of overwhelming energy that formed gigantic waves, with a momentum that was ferocious and torrential, pressing down towards Zhu Jiuyin.

Zhu Jiuyin followed suit, slowly extending his hand, circles of flowing light revolving a few times in his palm like a relayed torch.

In an instant, the Beiming Palace was back above Kunpeng Ancestor's head.

Immediately after, his body disappeared, leaving only a residual image that quickly swept past behind Kunpeng Ancestor.

Yu Yuan's mind stirred, realizing that he had accelerated his own time again, possessing unimaginable speed to such an extent that even Kunpeng Ancestor could hardly react.

Nevertheless, Kunpeng Ancestor being experienced, instantly turned around and pointed into the air, causing a thunderous sound as countless golden sword rains fiercely shot towards the position where Zhu Jiuyin appeared.

These golden sword rains were powerful, indeed forming a massive energy vortex that tore and sucked in everything around it, even time could not escape and was distorted and deformed under the immense suction of the vortex.

Zhu Jiuyin's figure flickered, forced to appear in front of Kunpeng Ancestor, raising his hand towards Kunpeng Ancestor to strike.

Kunpeng Ancestor hastily activated Beiming Palace to block Zhu Jiuyin while also summoning endless Green Fire Demon Thunder, bombarding towards all directions.

He knew that under the enhancement of the Time Law, Zhu Jiuyin's speed surpassed his, but this attack method that covered tens of thousands of miles effectively located the opponent's position.

What surprised him, however, was that Zhu Jiuyin revealed himself and even gave him a "you've been fooled" expression.

Kunpeng Ancestor had not anticipated that most of the Green Fire Demon Thunder, with such a vast and dense attack method, would fall onto the land below.

At this moment, their location was on Shouyang Mountain, below which lived a large number of the Human Race!

He was also unaware that someone was watching this battlefield, standing guard there, ready to mercilessly strike anyone daring to harm the Human Race.

In the next instant, a tall figure abruptly appeared in front of Kunpeng Ancestor, harshly swinging a huge hammer towards him.

Kunpeng Ancestor instinctively summoned the Beiming Palace, but still failed to block the mighty hammer strike, and along with the Beiming Palace was sent flying.

Only then did Kunpeng Ancestor see the identity of his assailant, unable to hold back he cursed aloud:

"Damn Tian Yuan Ancestor!"
