The moment the Four Swords revealed their Sharpness, Dragon Ancestor Zulong and Torch Dragon knew they were extraordinary. The Slaughter Great Dao's laws stretched endlessly, forming Order Divine Chains that descended and swept toward them.
Wherever the Four Swords' Sharpness passed, nothing could withstand them. Even the Dragon Ancestor Pearl was left with a white mark. Torch Dragon raised the Time Staff and twisted around, charging into the formation.
And so, two dragons and one demon battled until heaven and earth were overturned within the Immortal Slaying Sword Formation.
Sword energy stretched endlessly, Qiankun turned upside down, mountains and rivers shattered, and the sun and moon lost their light...
However, as time passed, after several hundred years, the battle grew easier and easier for Old Demon Luohou, who had come prepared. The Four Swords Formation also operated more and more smoothly.
Dragon Ancestor Zulong and Torch Dragon, who had initially been able to hold their ground, found the fight growing harder and harder.
After noticing this, Dragon Ancestor Zulong and Torch Dragon both thought of escaping the formation first and making plans afterward. With just the two of them, it was indeed difficult to fight that demon inside the formation.
"Hahaha... You want to leave? It won't be that easy!"
Old Demon had seen through their intentions and laughed loudly. "If you want to break this formation, then call over that other Dragon Ancestor! Let's see how I slaughter dragons! Hahaha..."
That other Dragon Ancestor was the Azure Dragon Emperor, who guarded the eastern extreme.
One could see just how swollen with pride Luohou had become by now.
And truth be told, with Luohou's cultivation, once he set up the Four Swords of Immortal Slaying Formation, dealing with three or four opponents of the same level really wasn't a problem.
