The Celestial Demon Clan invasion is different every time. In the history of the Qingfeng Heavenly Xuan Realm Human Immortal Clan, the largest invasion of the Heavenly Demon Clan, the strength of which was comparable to that of a half-step Golden Immortal-level powerhouse, there were hundreds of Heavenly Demons. At that time, the human immortal clan and the heavenly beasts in the Qingfeng Heavenly Xuan Realm were almost all slaughtered! Only a very small number of human immortal clans fled into the Gu Immortal King Secret Realm. With a few Zhen Clan Immortal Treasures and many Immortal Arrays within the Gu Immortal King's Secret Realm, he was lucky enough to prevent the crazy attack of those Heavenly Demons.

However, as time passed, some powerful Celestial Demons managed to leave, and some gradually died of old age. The alien Heavenly Demon Clan could not reproduce at all in the Qingfeng Tianxuan Realm, but the Human Immortal Clan was able to continue to reproduce new life, and in the end, the strength of the two sides gradually reversed, and the Human Immortal Clan finally launched a counterattack and regained control of the Qingfeng Tianxuan Realm.

Of course, there were only three times in the history of the human immortal race like this kind of devastating Heavenly Demon Invasion, the first time lasted for 100,000 years, the second lasted for 80,000 years, and the third lasted for 60,000 years.

Most of the Heavenly Demon Clan invasions were very small, and the spatial passage lasted for a short time, and only a few Heavenly Demons were able to break in.

"Slaughtering the ancient city is very rare, and it seems that the scale of this invasion of the Heavenly Demon Clan is very large. Murong Bing said suddenly.

"Our strength is still too weak, otherwise we can follow the half-step Golden Immortal to kill all those damn Netherworld Heavenly Demons. Sun Chen said fiercely.

They were all anxious in their hearts, but now that the Gu Immortal King Secret Realm had been temporarily sealed, prohibiting all immortals from going out, they could only wait for the order of the Gu Immortal King Palace in the Qingfeng Secret Realm.

Buzz! Buzz!

Suddenly, there was a buzzing sound on everyone's body, and then they immediately checked their own communication jade pendant and found that it was news from the Gu Immortal Palace.

"This invasion of the Heavenly Demon Clan is very serious, they are Heavenly Demons from the Origin Netherworld, and there are a lot of them. Now in the Gu Immortal King Secret Realm, they can only enter and not exit, and all immortals below the half-step Golden Immortal level must stay in the Gu Immortal King Secret Realm and stand by. ”

The news was brief, but it weighed heavily on the hearts of all the alternate elders. Many people's relatives were outside the Gu Immortal King's secret realm, and their fate was uncertain.

In addition to them, there were hundreds of thousands of immortals in the Gu Immortal King's secret realm, and they were all anxious, but they could only wait. They are not strong enough to help at all. With a half-step golden immortal in his hand, one person could easily kill a large group of them.

Half-step golden immortals are the backbone of the human immortal clan! Not only are they powerful, but they can also easily shuttle through the void to and from everywhere.

In the following days, the immortals in the Gu Immortal Palace's palace learned a lot of news through various channels, most of which were news of the battle between the half-step golden immortal of the human immortal clan and the heavenly demon of the Netherworld.

Because the human immortal clan participated in the battle were all half-step golden immortals, and many of them still had one or two immortal weapons! And they could also help each other, so they were generally only injured, as long as a few were killed in battle.

However, once the news of the death of the half-step Golden Immortal powerhouse of the Human Immortal Clan came out, it shocked and grieved countless immortals.

Although the human race killed four half-step golden immortals in succession, the Netherworld Heavenly Demons died even more. The Netherworld Heavenly Demon, whose strength was comparable to that of a half-step golden immortal, was killed by a full sixteen.

The remaining Heavenly Demons have also learned their lesson, and they no longer sweep the human immortal clan and hide everywhere. The heavenly demons who can escape under the round-up of the half-step golden immortal powerhouses of the human immortal clan are either extremely powerful, or their escape methods are extremely demonic.

A few years later, it would be difficult for the half-step golden immortals of the human immortal clan to discover the traces of the Heavenly Demon of the Netherworld.

Over the years, Zhao Yu still put everything behind for the time being, and devoted himself to enlightenment and cultivation.

Suddenly, a voice came from his body, and then he received a message from the summons jade pendant.

"The Gu Immortal Palace summoned all the Xuan Immortals to hold a secret meeting, and let all the Xuan Immortals go to the main hall of the Gu Immortal Palace. After Zhao Yu received the news, he hurriedly put away the fairy sword.

"Zhao Yu, the Gu Immortal Palace suddenly held a Xuan Immortal meeting, what could it be?" Murong Bing also received the news and hurriedly asked.

She has been staying with Zhao Yu these days, Zhao Yu has comprehended the Immortal Sword Technique, and she has comprehended the Immortal Array.

"I guess it's about the invasion of the Netherworld Heavenly Demons! If my prediction is correct, the Gu Immortal Palace is probably going to give us a mission, and our peaceful days are probably coming to an end. ”

"We're going to be sent to war too?" Murong Bing said with a look of surprise.

"It's just my guess, let's go. Zhao Yu hurriedly said.

Immediately, the two walked side by side towards the exit of the Qingfeng Secret Realm.

。。。。。。

The main hall of the Ancient Immortal Palace.

Whew!Whew!

Figures flew from everywhere, landed in front of the temple door one after another, and then quickly walked into the hall.

The main hall is very majestic, and the interior layout is also very simple.

In the center of the main hall sat twelve figures, and the middle one was the master of the Chuliu Palace.

"Let's sit down. After Zhao Yu and Murong Bing entered the main hall, they quickly sat cross-legged on the two adjacent futons.

"Zhao Yu, you have also arrived. Not long after, several figures also walked up to Zhao Yu's side, and one of them said with a smile.

"Fei Song, Murong Bing and I have just arrived. Zhao Yu left and glanced at those people, smiled slightly, and said.

Soon after those Xuan Immortals entered the main hall, they all chose a futon and sat down cross-legged, and whispered to each other.

Half an hour later, the huge hall door slowly closed, and all the Xuan Immortals looked at the twelve half-step golden immortals sitting cross-legged in the void at this time.

"All the Xuan Immortals have arrived, this meeting is about the invasion of the Heavenly Demons of the Netherworld, you may have guessed it. Not long after, the palace master of Chuliu spoke.

"Since three years ago, a spatial passage formed by accident has connected one of the Xuan Realms in the Origin Demon Realm to our Qingfeng Heavenly Xuan Realm, and the peaceful days of our human immortal clan have come to an end. Many Netherworld Heavenly Demons have entered the Qingfeng Heavenly Xuan Realm, and they have wantonly slaughtered and devoured our human immortal clan. The palace master of Chuliu said again.

"In the beginning, we half-step golden immortals killed a lot of Quiet Heavenly Demons, but the further we got, it is difficult for us to find their traces, and now it is almost difficult to find another Netherworld Heavenly Demon. After a pause, the Palace Lord of Chuliu continued.

"According to our judgment, there are at least five half-step Golden Immortal-level Heavenly Demons who have fought against us are still alive, and we suspect that there should be half-step Golden Immortal-level Heavenly Demons who have never fought against us lurking! Suddenly, Chu Liugong's face changed slightly, his eyes flashed with killing intent, and he said slowly.

"The Netherworld Heavenly Demon hidden in our Qingfeng Heavenly Xuan Realm, in addition to the half-step Golden Immortal-level Heavenly Demon, there are many other Heavenly Demons who are also hiding. For the Heavenly Demons, the immortal power in our human immortal clan is their tonic, which is of great benefit to their strength. If they are allowed to lurk in various places and continue to secretly devour our human immortal clan, some half-step golden immortal-level heavenly demons will also be born from those slightly weaker heavenly demons!" Not long after, Qian Chengguan also said.
