While Ling Chen was about to face the strongest opponent he's never faced in his life to save his friends, there was also a heavenly frightening event happening in the Heavenly Demon Sect's Domain. The Heavenly Demon Sect was also about to face the biggest crisis since its foundation.

The invincible and unbeatable Imperial Army of the mighty Yan Empire, the strongest of the fifteen great influences throughout the Heaven Desolate Region, that has been dormant for the past hundred years had suddenly awakened from its deep slumbers like a giant prehistoric beast, hungry for blood and chaos.

The earth trembles as if there were an earthquake and thunderous rumbles echoed across the sky as this unbeatable great army was entering the domain of the Heavenly Demon Sect.

A swarm of powerful demon beasts was flying above the sky of the Heavenly Demon Sect's Domain with countless imperial soldiers riding on top of them while the ground was littered with tens of thousands of imperial soldiers clad in red crimson armors. In their heavy armor, the invincible imperial army looked like a moving fortress of steel.

Furthermore, even though the mighty Yan Imperial Army has invaded the Heavenly Demon Sect's Domain, they didn't attack any of the kingdoms or influences under its rule, their destination was the Heavenly Demon Sect itself.

The news about the sudden invasion of the Heavenly Demon Sect's Domain by the Yan Imperial Army spread throughout Heaven Desolate Region like a wildfire and it caused quite a stir. Many people were quickly alarmed.

"Could it be that the Yan Empire has finally decided to unify the whole Heaven Desolate Region and choose the Heavenly Demon Sect as their first stepping stone?" An elder from a different sect said.

"Stepping stone! The Heavenly Demon Sect isn't as weak compared to the Yan Empire as you thought." Said an elder who seemed to have some knowledge about the Heavenly Demon Sect's true strength.

" Huh! You may be right. I also think that The Yan Empire only invades the Heavenly Demon Sect because of that mysterious Devouring Battle Techniques." Another elder said.

Meanwhile, many influences and kingdoms under the rule of the Heavenly Demon Sect were perplexed. Why would the Yan Imperial army invade the Heavenly Demon Sect's Domain? All of the influences within the Heavenly Demon Sect's Domain paid great attention to this invasion. They all sent their experts out right away to figure out the story.

At the same time, the news about the Yan Empire invading the Heavenly Demon Sect made the other great influences think about many things.

Many great sects were privately discussing the expedition of the Yan Empire. Some said that it was for the devouring battle technique while others believed that it was the Yan Empire's first move in the quest to unify the Region. There was also a group that believed that it was for both.

The Heavenly Demon Sect was one of the fifteen great influences and had deep heritages. Just their top tier Heaven rank Battle Techniques was enough for people's eyes to become reddened with greed.

Not to mention the sudden appearance of that demonic devouring battle technique, this one alone was still enough for countless sects to be overwhelmed with avarice. At the same time, they all contacted their spies to make sure that the news about the invasion was true.

The moment the news was confirmed to be true, everyone knew that the Peaceful Era of the Heaven Desolate Region has ended and the Era of Chaos was about to begin.

At the same time, whether it was the remaining four evil sects such as the Evil Dragon Sect, the Poison Sect, The Yin Maiden Sect, and the Evil Blood Sect began to prepare for war.

Not only them, but the remaining righteous sect such as the Beast Hall, Martial God Sect, Azure Dragon Sect, the Pure Maiden Sect, The Alchemy Dao Sect, and the Blacksmith Sect were also making their preparation.

Meanwhile, the remaining two great Empires, the Silver Moon Empire, and the Burning Sun Empire were already closing their borders and had their imperial armies on stand by.

At this moment, the entire Heaven Desolate Region was on the verge of an all-out war due to the sudden movement of the Yan Empire.

....

Heavenly Demon Sect.

Even before the Yan Empire had entered into the domain of the Heavenly Demon Sect, the higher-ups of the sect had already known about their plan to attack them.

As such, the moment the Yan Imperial army had set foot into the Heavenly Demon Sect's Domain, In a flash, the sound of bells ringing echoed throughout the entire sect, warning the disciples that enemies were approaching!

At the same time, both the top and bottom of the sect were getting ready for battle. They had even activated their defensive array formation known as the Crescent Wall Barrier.

Under the crescent wall barrier, the entire Heavenly Demon Sect was enclosed by an azure round barrier made of true qi energy like an umbrella.

The Crescent Wall Barrier was the most powerful defensive array formation owned by the Heavenly Demon Sect. It was said that it had the power to resist the powerful attacks from even a Martial Saint Powerhouse.

Like most powerful array formations, the Crescent Wall Barrier was powered by the spirit veins of the sect. As such, unless the spirit vein of the Heavenly Demon Sect was drained completely, the Crescent Wall Barrier would continue to protect the sect to the very end.

While Ling Tian, the sect master of the Heavenly Demon Sect, was making his last preparation for the war within the main hall of the Heavenly Demon Palace with the higher-ups of the sect, an elder of the inner sect suddenly barged in as he anxiously shouted:" Sect Master, Sect Master, Sect Master, we have a problem."

Seeing the anxious elder that barged within the main hall without permission, Ling Tian who was sitting in the main seat couldn't but sternly said:" Elder Zao, you should know the importance of that meeting. So what's so important that you couldn't even wait until the meeting over to tell me."

Not only Ling Tian, but even the other great elders also looked annoyed by the sudden interruption of the inner sect elder. Right now, the sect was facing a huge crisis and they needed to quickly come up with a plan to battle and push back the incoming Yan imperial army.

"Young master Ling Jian has left sect along with his subordinates. When we tried to stop him, he killed three inner sect elders and ten disciples and fled." Said the elders with an ugly and anxious look on his face.

He still couldn't believe that the young master that he looked up to had betrayed the sect when they were about to face a life and death crisis.

While the elders within the main hall became dumbfounded by this sudden turn of events, Ling Tian didn't look surprised at all.

"It seems like he has made his choice." Ling Tian said with a regretful look on his face before he ordered the elders to continue the meeting.
