Chapter 921： Secret Realm Open

The gloomy breath made everyone feel depressed, as if even breathing became difficult.

"Is this the secret realm of the heavenly devil?"

Many people raised their heads and solemnly looked at the gloomy atmosphere on the sky.

The Heavenly Demon Secret Realm is opened once in a hundred years. At this moment, almost 99% of the people in the square have seen this Heavenly Demon Secret Realm for the first time, unless some top martial king over a hundred years old.

However, even the top martial kings who were over a hundred years old were just watching from afar outside the square. As for the martial kings who have entered the secret realm of heavenly devil, there are very few.

"Is it a secret realm? It's been a long, long time since I felt such a kind atmosphere!"

And when the atmosphere of the heavenly demon secret realm emerged, among the crowd outside the square, a person wearing a black cloak suddenly raised his head, staring at the magic secret realm that day with twinkling eyes, his expression excited, a trace of strange color bloomed from his eyes. Out, at the same time a strange aura was exuding from his body.

This breath is extremely cryptic, but it is somewhat similar to the breath in the secret realm of the heavenly devil, as if it had the same origin.

"Ok?"

On the square, Qin Chen seemed to feel something, and suddenly looked into the crowd.

However, he swept his gaze, but found nothing unusual, frowned and said, "Is it an illusion?"

Without thinking too much, Qin Chen turned to look at the mysterious realm of the heavenly devil.

Buzzing!

At this moment, the big formation in Chaotian City suddenly opened, and a series of astonishing breaths rose to the sky, combined with the gloomy sky.

Rumble!

Under the shocking eyes of everyone, the gloomy sky in front of them unexpectedly revealed a strange space. Behind that space, there seemed to be an ancient earth looming, exuding a desolate and profound ancient atmosphere.

"What a terrifying aura, is this the secret realm of the heavenly devil?"

"Look at the sky, behind that space, there seems to be a continent."

"Unbelievable, in the void above our Chaotian City, there is actually a continent hidden?"

"It is said to be the battlefield where our human race and alien race fight."

The crowd was shocked, and their hearts were greatly touched.

The secret realm is a small space in the ancient times, and there are countless warriors who have explored the secret realm.

Like the Black Death Swamp that Qin Chen explored at the beginning, it actually belongs to a kind of secret realm. Various spaces are stacked together and are relics of ancient times.

The ancient southern capital at the time was naturally a kind of secret realm. The palace hidden in the void was extremely terrifying.

But compared to the Heaven Demon Secret Realm in front of him, both of them are a bit worse.

The mysterious space above the sky exudes an infinite aura. If people with better eyesight can even see, the end of the endless chaos and void even hides a vast continent.

"From the perspective of breath, this heavenly demon secret realm is at least a high secret realm. No wonder this place of hundreds of dynasties attaches so much importance."

Qin Chen has seen too many secret realms in his previous life, and his understanding of secret realms is far beyond average. He clearly feels that the level of this heavenly magic secret realm is very high. If it is not for the powers above Wu Huang to enter, it will definitely attract a large number of them. Emperor Wu came.

It is a pity that due to the restrictions of the level, this Heavenly Demon Secret Realm is only spread in the land of a hundred dynasties.

"The aura of this heavenly demon secret realm is somewhat similar to the original Black Death Marsh and Ancient Southern Capital. Is there any connection between these secret realms?"

At the same time, Qin Chen keenly felt that the auras of Ancient Southern Capital, Black Death Swamp, and Heavenly Demon Secret Realm were very similar. On the surface, they were different, but in essence, they were exactly the same.

"Qin Chen, how does grandpa feel the aura of this Heavenly Demon Secret Realm and my Sanluo Secret Realm in the five northwestern countries?"

At this moment, an old voice rang in Qin Chen's ears, but it was Qin Batian who transmitted the sound to Qin Chen.

"It's very similar to the Sanluo Secret Realm?"

Qin Chen was taken aback.

He has naturally heard of the secret realm of Shengluo. It is the most powerful secret realm in the Demon Ancestral Mountain Range of the Five Northwest Countries.

However, there are many dangers in it, so many of the five powers have just searched the periphery and cannot enter the depths.

But among them, there are many relics from before the Dark Ages. Qin Chen remembers his mysterious rust sword at the time, and it seems to have been excavated from the secret realm of Saint Luo. Until now, Qin Chen has not figured out his mysterious rust sword. True face.

There is also the alien demon armor on his body, which was also a strong man in the Dawei Dynasty, found in a secret realm in the Demon Ancestral Mountain Range.

Obviously, the secret realm is very likely, that is, the secret realm of Saint Luo.

In addition, the prohibition on the different demon armor is similar to the prohibition in the ancient southern capital, and the ancient southern prohibition is exactly the same as the palace stone pillar that Qin Chen saw deep in the bottom of the Black Death Marsh.

The combination of all this made Qin Chen instantly understand that although there are many secret realms near the Land of Hundred Dynasties in the Northern Horizons, they should actually originate from the same age in ancient times.

"In that case, all mysteries are likely to be related to alien races that antagonized human races in ancient times."

Qin Chen vaguely guessed.

And while he was pondering, Chaotian City's formation finally came into contact with the heavenly demon secret realm in the sky.

Boom!

The sky instantly tore open a huge hole, and at the same time a colorful beam of light descended from the sky, through the beam of light, one could vaguely see the desolate and vast world behind the beam of light.

"Huh? No, this time the passage of the Heavenly Demon Secret Realm is smaller than the record?"

Suddenly, a low voice sounded, and the master of Tianji Pavilion Shangguanlu's face suddenly changed.

"what happened?"

Shangguanlu's exclamation immediately attracted the attention of everyone, and they all stared.

The ancestors of the seven dynasties also looked suspicious.

Shangguan Lu looked solemn, and a compass-like treasure appeared in his hand. Several pointers trembled constantly, and finally stopped.

His face turned pale, as if he had seen something unbelievable, and murmured: "Impossible, how is this possible?"

"Shangguanlu, what happened?"

"It is shown on the heavenly secret disk that this Heavenly Demon Secret Realm was opened by someone about 18 years ago, so this time the energy is insufficient, so the opened transmission channel is only 80% of the normal size." Shangguan Lu stared. Said with his eyes.

"It was opened eighteen years ago? How is this possible?"

Everyone in the land of a hundred dynasties was stunned.

The Secret Realm of Heavenly Demon is sealed in the void space above Chaotian City. It will be the closest to Chaotian City every 100 years, and the seal will reach its weakest point before the passage can be opened.

And eighteen years ago, the seal was still in good condition, how could someone be able to open the magic mystery that day. What's more, even if someone opened the heavenly demon secret realm 18 years ago, the people in Chaotian City should have noticed it, how could it be so silent?
