It's just that they would never have imagined that the safest place in their opinion is the most dangerous place, and no one thought that the biggest crisis of the Celestial Clan came from the Holy Pool, but by the time all the Celestial Clan found out, it was already too late.

After a year of retreat in the Xuanjing Mirror and thoroughly refining the prologue of that Great Dao, he finally took the most important step.

"Boom!"

An earth-shattering terrifying aura swept from the top of the holy mountain, and Xuanjing's entire person was suspended above the holy pool, and endless terrifying light power continued to pour from the holy pool into his thin body. At this moment, the Xuanjing is a supreme being high above, looking down on all living beings.

Under the terrifying aura of the Xuanjing, everything in heaven and earth is an ant, even the existence of the realm of immortality and reincarnation is not worth mentioning at all, and even the breakthrough of the Xuanjing, there is a faint fiery red heavenly punishment cloud condensing above the nine heavens.

However, the person who broke through was the Xuanjing, the Great Elder of the Heavenly Clan, so this Heavenly Punishment Cloud was not condensed after all.

"Buzz!"

The holy light rushed to the sky, the light shone on the nine heavens and ten earths, at this moment, the Xuanjing was a supreme saint, and the light that bloomed from him turned into a pillar of light and soared straight into the sky, piercing the sky!

"The Great Elder has finally broken through the Immortal Realm!" Seeing this scene, many Heavenly Clan powerhouses who were originally worried that something bad would happen breathed a sigh of relief in their hearts, even a few Heavenly Clan Ancestors who did not show up also showed a smile on their faces at this time.

"This power is really powerful, I like this dark power more than the Bright Dao!" Xuanjing, who stood in the air and continued to devour the power of the Holy Pool, was no longer an old man, but a young man.

It's just that although the Xuanjing at this time is still blooming with a light power that is enough to shine on the nine heavens and ten earths, his eyes have become extremely dark at this time, and if this scene is seen by other celestial clans, it is definitely enough to cause earth-shattering waves.

However, the first one to notice that something was wrong with the Xuansheng was the Xuansheng who was guarding outside the holy pool, at this time, Xuansheng suddenly opened his eyes, staring at the Xuanjing suspended in the holy pool, and a dignified expression suddenly flashed on his old face.

"Aura of darkness?" At this time, Xuan Sheng muttered, his tone was incredulous, because he didn't know how long it had been since he had felt the aura of darkness. Today, however, he felt the breath of dark power at the entrance of the sacred pool, which contained the power of endless light.

No one dared to believe this anyway, even if he was an immortal realm being, he couldn't believe that there would be a dark force in the place that was known as the brightest.

This is absolutely impossible, because darkness and light are always opposites, and there can be no dark power in the holy pool under the infinite power of light, just like there is fire in the deep water.

After the Xuan Sheng discovered this, there was soon another Supreme Realm who noticed this, this Supreme Realm existed, even older than the Xuan Sheng, and lived for a long time, even for an unknown number of years.

Xuan Xuan, one of the oldest and most powerful ancestors of the Celestial Clan, had broken through the Supreme Realm many years ago, and for the long and endless years, he had been in retreat in the Holy Mountain, and only a handful of Celestial Clans knew of his existence.

"Ancestor!"

A figure appeared in the void out of thin air, Xuan Sheng immediately got up to greet him, and when he saw the appearance of Xuan Xuan's figure, he understood the seriousness of the matter.

You must know that although his Xuan Xuan Ancestor is an existence in the Immortal Realm, there is a huge gap between the two. After all, there is also a huge gap between the immortal realms.
