The purpose of this purge was to remove unknown threats from the world of cultivation. As for how they were to remove them, that was not something they could even begin to guess at.

In order to deal with the impending calamity, a group of true experts wholeheartedly focused on comprehending the Dao.

After Lei Ao and the others left, the Ten Hidden Dragons began to declare war on the Evil Dao Alliance.

For a time, there were undercurrents in the cultivation world. In the face of Lei Ao who had gone crazy and refused to give up, they chose to endure.

Now, they could no longer avoid the actions of the Ten Hidden Dragons because the power behind them was too great. It was not difficult for the spies in the cultivation world to search for them.

Unless they were completely hidden from the world, then there was no need for the Evil Dao Alliance to exist.

Therefore, the Evil Dao Alliance quickly responded to the declaration of war by the Ten Hidden Dragons, with the Four Devils as the leaders, and started a war against the entire cultivation world.

As a result, An Yun and Huang Xin, who were planning to quietly go into seclusion, had no choice but to come out and fight.

With the strength of the Ten Hidden Dragons, it would be unrealistic to fight against the entire Evil Dao Alliance. After all, they were powerful forces that had been passed down since ancient times.

This could be confirmed just from the Four Devils themselves. Even the younger generation had experts of this level. How could those old demons that had lived for thousands of years be lacking?

Furthermore, all of the Alliance Masters of the Evil Dao Alliance have the title of Evil Emperor, and the Evil Dao Alliance that came out this time did not find any trace of the Evil Emperor, so he had been hiding behind the scenes the entire time.

Other than the Evil Emperor, the Evil Dao Alliance's fixed positions included the Third Elder, the Five Evil Envoys, and the Seven Protectors. None of these people had shown themselves.

The most conservative estimate was that their strength was not below the sage realm even if they had not stepped into the realm of Immortals.

Therefore, the cultivation world's future was not too optimistic. The Evil Dao Alliance's previous restraint was not because they were afraid, but because they were holding back their strength. They might be worried about something.

Now, the ten Hidden Dragons had officially declared war. Not only did they represent themselves, they also represented the forces backing them.

As soon as these hidden sects moved, the entire cultivation world was swept away. The sects that had been persecuted by the Evil Dao Alliance all responded.

All of a sudden, the Evil Dao Alliance became the enemy of everyone. War broke out everywhere.

In the first big battle, Yi Zhen and his team led experts to wipe out a branch of the Evil Dao Alliance and killed over a hundred enemies. They wanted to capture and capture the Evil Dao Alliance, but unfortunately, those loyal people would rather self-destruct than reveal even half a sentence.

Two days later, the experts of the Evil Dao Alliance led by the Sky Demons had turned a city south of the cultivation world into ruins. Not a single living soul was left inside the city, including mortals.

After a few more days, Little Devil Star Shi Tianwu single-handedly intercepted a group of Evil Dao Alliance experts and left after the battle, leaving behind the corpses on the ground.

In the second month, Lin Yuan City was ambushed by the Evil Dao Alliance. Fortunately, Lan Haimei and Nangong Mengjun were in the city and blocked the four Devils' attacks. This allowed Yi Zhen and the others time to return to help.

This battle was extremely tragic. After two days of bloody battle, as more and more experts joined the battle, the Evil Dao Alliance decisively retreated. This time, both sides suffered heavy losses.

In the fourth month, the Little Evil God encountered the most mysterious of the four devils. When Yi Zhen and the others arrived, the battle was already over.

In the seventh month of the same year, the demons led a large group of experts to attack Lin Yuan City. The fourth of the four most mysterious demons finally revealed their true appearance.

Other than the heaven, earth, and human devils, the fourth devil's title was the Evil Demon. It had once fought against Lei Ao while retreating, and the outcome of his battle with the Little Evil God was unknown.

The Evil Dao Alliance that he participated in the battle had a much fiercer attack than last time. Moreover, besides the four of them, there were also seven Protectors.

There were a total of eleven experts that had entered the circle, and the number of people was greater than the number of people in the circle.

In the beginning, Yi Zhen and the others fell into a bitter battle. With the Evil Demon, Sky Demon, Earth Demon and the seven Protectors as the leaders, the ten powerhouses entangled them, while the Human Demons led the other powerhouses to launch a fierce attack on Lin Yuan City.

Because the elders of the Evil Dao Alliance had never appeared in the world, the experts of the hidden sects didn't participate in the battle. No one would have imagined that their opponents would send out so many experts this time.

Even if the hidden sects received the news and rushed over, the war would probably be over by then.

Without the protection of a group of true disciples, there was no one in Lin Yuan City who could resist the Humans and Demons. Wherever he went, Qi warriors would fall in droves.

As soon as he saw his companions die in front of him, his eyes immediately turned red with anxiety. He charged left and right with his golden body, and even after a few assaults, he was forced to retreat.

After a long period of time, not only did Linyuan City fall into a crisis, even Yi Zhen and the others were unable to protect themselves.

The demons were too strong. Only the Blue Ocean Eye could deal with them, but the Heaven, Earth, and Heaven Demons as well as the Seven Protectors were not weak. They were not weaker than people with Divine Veins.

Gradually, the eight began to turn their offense into defense, forming an alliance line, only then were they able to resist the attacks of the Evil Dao Alliance.

As the saying went, a long defense meant certain defeat. Once the Human Demons found the time to join the battle, the eight of them would be in danger.

"Fire God's Descent!"

After fighting for a long time, Nangong Mengjun was the first one to start burning her bloodline.

It wasn't because she wasn't strong enough, but because the fight was really depressing. The Nangong family's divine flame was peerless in this world, but she didn't dare to use it carelessly.

Why? This was because not only did they have enemies by their side, but they also had their own people. It was fine if they injured their enemies, but if one of them was unlucky and had their Sky Light ignited, it would be extremely troublesome.

Not only her, but also Bluesea. The more powerful moves of the Mysterious Ice Formula were large scale attacks. In the battlefield, the two of them were the ones most restricted.

Overall, he was only able to unleash about half of his true strength.

Therefore, this was the reason why Lan Hai Tong had always taken the defensive stance when facing the attacks of the demons.

One of them also saw this. They had tried to pull the battlefield apart, but the evil demon had firmly grasped this weakness and refused to let it go.

Possessing the Fire God, Nangong Mengjun's body emitted a strong heat wave, forcing everyone around her back a few hundred feet. One of the seven protectors of the Evil Dao Alliance who was fighting with her immediately took action.

The Evil Dao Alliance was not inferior to any other family in ancient times, even when both of them were burning their bloodline.

The fierce attacks collided with each other. Even the sky was burning red where Nangong Mengjun stood.

On the other side, there was an imposing evil aura. One of the Seven Protectors had formed a huge Evil God form behind him, facing Nangong Mengjun's Fire God from a distance.

Four hours later …

The Human Demons floated in the sky above the Abyss City and proclaimed loudly with an overbearing attitude:

"From today onwards, Lin Yuan City will cease to exist!"

At this time, the battle had almost come to an end. The disciples of the various sects that were left behind to guard the city had all died. Only a small portion of them had managed to make it out alive.

Only the Eight Hidden Dragons were still holding on. Seeing that there was no hope for them to save the city, they decided to give up protecting the city, forcing their opponents to the side. After opening up a distance, they displayed their true strength.

The situation had suddenly reversed. Lan Hai's eyes were firmly suppressing the evil spirits. The rest of them were at least evenly matched.

Among them, Niu Meng and Blood Wolf were the ones who fought the hardest. These two were fanatics who were engaged in combat. The earlier grievances, which had been suppressed, were released in an instant.

As their opponents, Sky Demon and Earth Demon had suffered greatly and could only gloomily choose to defend themselves.

The words of the Human Devil caused Yi Zhen and the others to be a bit distracted. They couldn't help but feel a desolate feeling rising in their hearts.

Lin Yuan City, which had stood tall and upright for thousands of years in the cultivation world, still could not be maintained.

There was no one left in the city. The Humans and Demons had begun to destroy the city. He was in no hurry to act, so he ordered his men to slowly demolish the city.

In this way, the eight Hidden Dragons' eyes immediately turned red. They desperately tried to turn around to stop him, but they couldn't escape from their opponent.

At this moment, a golden cloud appeared in the west. Along with the resounding Buddhist chant, reinforcements from the Buddhist Sect finally arrived.

The middle-aged monk in the front wore a golden monastic robe, and had a benevolent Buddhist appearance. He was clearly a thousand miles away, and in a few steps, he arrived in the air above the city.

With just a Buddhist prayer, the experts of the Evil Dao Alliance were sent out of the city.

The hidden powerhouses had finally appeared!

Although they seemed to already be standing at the peak of the cultivation world, and their bodies were also at the Divine Veins, in reality, all of the great underworld clans were hiding some true experts.

He was an expert above the Immortal Realm, comparable even to the realm of immortals.

"Who are you?" Seeing that the newcomers were quite strong, the Human Demons immediately retreated some distance away.
