A hundred thousand years ago.
Southern Border, Xuan Ci Mountain.
It was night time, darkness was everywhere. Wind and thunder rumbled, lightning flashed across the battlefield at times.
Partway up Xuan Ci Mountain, more than ten Gu Masters' corpses were on the ground.
It rained heavily, but it could not wash away the thick and bloody smell of the place.
A battle had just ended, there were only two people left on the battlefield, the victor was evident.
"Hahaha!" A young man laughed while looking at the sky, his eyes were blood-red, his expression was filled with bloodthirst. He slowly walked towards the other Gu Master.
The other Gu Master was an old man, he was heavily injured and could not battle anymore. He retreated in a hurry, but he tripped and fell into the mud.
