In this fierce battle, the heads of the Cangchen Emperor Sect, the Budong Emperor Sect, the Shihun Emperor Sect, the Qiankun Emperor Sect, and the eight original clans were all directly killed by the quasi-immortal emperor powerhouse of the Yuan Clan, and the scene was extremely tragic.

The remaining heads and masters of the Nine Extremes Imperial Clan, Ancestral Dragon Clan, Candle Dragon Clan, Yinglong Clan, Arbitration Imperial Court, Innate Palace, and Heavenly Fate Immortal Palace were all seriously injured.

Moreover, the powerful figures below the Immortal King realm in these forces were almost completely wiped out under the fierce attacks of the Human Ancestor, the Chaos Emperor, the Six Paths of Heaven and Earth, Elder Xue, Ye Zhetian, and other powerful figures.

At this moment, both sides' forces converged, and the situation became extremely tense.

Seeing that the time was ripe, Yuan Xingdao was preparing to launch a final attack to kill all the powerful figures from the eleven forces in one fell swoop.

However, at this critical moment, Ouyang Bai raised his right hand without hesitation, put his index and middle fingers together, and pointed directly at his brow.

In an instant, a drop of bright red blood essence floated out from between his eyebrows, as if it contained boundless power.

Immediately afterward, Ouyang Bai shouted without hesitation, "With my lifeblood, I call upon my ancestor!"

His voice, like thunder, echoed in the air, deeply moving everyone.

As his shout faded, the drop of blood suddenly burst forth with a dazzling light, as radiant as the sun.

In the blink of an eye, the essence blood rapidly expanded, forming a huge spatial energy vortex that spun wildly, as if it were about to devour the entire world.

Then, suddenly, a cold snort rang out like a thunderclap.

The sound seemed to come from the heavens and earth, or perhaps it was the whisper of the Great Dao, carrying boundless majesty and power, and boomed in everyone's ears.
