While Huang Xiaotian was hiding in the moss and trying his best to conceal his aura, his junior brother, Bu Canghai, was also in danger. He was trapped in a hidden formation in a large hall.
The Xuankong Marquis' tribe.
This was a large tribe that had been founded on formations tens of thousands of years ago.
The Xuankong Marquis' tribe had lost millions of people overnight. Something had even happened to the tribe. The base of the tribe's protective formation had been affected. No one knew what had happened to the tribe, but the area within 100 kilometers of the Xuankong Marquis' tribe had been separated from the wasteland and turned into a secret realm.
However, the cultivators of the Xuankong Marquis' tribe had mysteriously disappeared without a trace. There were no records of what kind of disaster the cultivators of the Xuankong Marquis' tribe had gone through.
The secret realm did not occupy a large area, only about 100 kilometers in radius. However, the surroundings of the Xuankong Marquis' tribe had been completely preserved because of the formation.
It was rumored that the Xuankong Marquis' tribe had been powerful for a time. During that era, the overall strength of the desolate border region was much stronger than it was today. There were at least a few human battle divisions that were not weaker than the Xuankong Marquis' tribe. However, they had all been destroyed in the long river of time.
Since it had turned into a secret realm, there were naturally many cultivators who came to explore it and search for opportunities. After all, the foundation of a marquis' tribe was enough to make ordinary cultivators envious.
For tens of thousands of years, it had attracted many cultivators from the desolate border region to explore its secrets. After all, the Xuankong Secret Realm had been explored by countless cultivators over the years.
In the center of the secret realm, which was also the center of the Xuankong Marquis' tribe, there was a large hall. Although it was surrounded by the secret realm formed by the formation, the stone hall had still become dilapidated under the corrosion of time.
Buzz!
At this moment, there was a spatial ripple outside the hall. If it were not for this spatial ripple, people who passed by would not have noticed that there was a restriction in the hall.
This restriction came from the inside of the main hall because there were cultivators attacking the main hall. However, they seemed to be unable to achieve anything.
The person trapped in the hall was Xiao Chen's disciple, Bu Canghai.
He had been in the Mystical Space Mystic Realm for five days under Xiao Chen's orders. With his innate talent of Soul Concealment, most of the formations in this space could not detect him. Therefore, he ignored everything in the mystic realm and went straight to the depths of the mystic realm with ease.
Back then, Marquis Xuankong's tribe was founded on formations, so naturally, there were formations in the tribe. Even now, there were still many formations in operation.
There were even some broken formations that combined with the surrounding environment to form other formations.
It took Bu Canghai less than half a day to enter the central area of the Mystical Space Mystery Realm. He had been trapped in the hall for a few days.
"What kind of formation is this?"
Bu Canghai frowned. After being trapped in this hall for several days, he was starting to feel a little anxious.
The hall looked like an ordinary hall that used to belong to Marquis Xuankong's tribe. From the outside, there was nothing special about it.
A few days ago, after entering this secret realm, Bu Canghai had searched the entire secret realm, but to no avail. However, as soon as he entered the hall, something unexpected happened. Even his Soul Concealment Physique was broken.
After being trapped for a few days, Bu Canghai had also discovered something different in the palace. In the somewhat dilapidated palace, there were faint traces on the stone walls. However, due to the passage of time, those traces had already become somewhat mottled and indistinct.
Since he could not leave the hall, he had no choice but to start studying the marks on the stone walls.
"Is this a Formation Technique?"
Although he wasn't a formation master, his senior and junior brothers had been cultivating together with Tian Fang for many years, so they had learned some general knowledge about formations.
Knowing wasn't the same as understanding, not to mention that it was a blurry technique. He had tried all kinds of methods in the past few days, but it was difficult for him to walk out of the main hall. Even the teleportation token of So Near and So Far Pavilion was blocked by the array formation of the main hall.
There were a few skeletons around him. Some of their beast robes had even decayed, leaving only broken remains. Their faces could not be seen clearly.
These were all martial artists who were trapped in the hall.
"Big Senior Brother said that all Formations have fluctuations when they operate. Even a Heaven Grade Formation is no exception."
After a few days of frustration, Bu Canghai finally calmed down. He sat cross-legged in the hall and began to use his Spiritual Will to scan the hall.
Although he was only at the fourth level of the Heavenly Building Realm, his Spiritual Will had already reached the level of a Venerable because of his Spiritual Talent.
His Spiritual Will scanned the hall again and again, trying to sense the fluctuations in the hall. Just like that, three days passed. Bu Canghai did not move at all. When his Spiritual Will was exhausted, he would take out a Soul Nourishing Pill and consume it.
Buzz!
A faintly discernible Spiritual Will constantly scanned the hall, not letting go of any corner.
Finally, five days later, Bu Canghai found a trace of fluctuations in the hall. This fluctuation was very weak, and it did not derive from the hall, but transmitted the fluctuations outside the hall.
Ten days later, the fluctuations came again and transmitted to the outside of the hall.
"Is it absorbing energy from the outside world to maintain the operation of the Formation?"
When the fluctuations disappeared, Bu Canghai opened his eyes. There was a touch of relief in his eyes. After ten days, he finally found the fluctuations of the Formation in the hall.
Next, he was not in a hurry, but waited for the next time the Formation transmitted the fluctuations. Any Formation might be operated with the help of the power of crystal stones, or it might be supplied with other energy. Otherwise, it could not operate for a long time.
Looking at the broken corpses around, it could be imagined that this Formation had been operating for a long time. Naturally, it needed to be replenished with energy. Otherwise, the Formation would collapse on its own.
Feeling the fluctuations of the Formation, Bu Canghai also let out a sigh of relief. He looked at the corpses around him. These were the people who were trapped in the hall.
Although he was a Heavenly Building Realm warrior, and although he had already abstained from eating, with the primordial stones and elixirs he carried, he might be able to support himself for a year and a half. But after a long time, without the replenishment of primordial stones and elixirs, his vitality would eventually dry up, and that would be a dead end.
Another five days passed. Bu Canghai took the Soul Replenishing Pill and other elixirs to adjust his Battle Qi and Divine Soul to the best state, waiting for the fluctuations to come again.
At this moment, there was a Spiritual Will floating out of his body, wrapping his whole body. The talent of Soul Concealment was displayed, and even his whole body gave off an illusory feeling.
Buzz!
Finally, the fluctuations arrived and began to transmit to the outside of the hall.
"I don't believe it!"
In an instant, Bu Canghai stood up and exhaled. Suddenly, his whole body turned into a black shadow and collided in the direction of the fluctuations.
Buzz buzz buzz!
The originally peaceful hall was like an exploding pot of oil, bursting out with a buzzing sound, giving rise to an explosive wave. When Bu Canghai collided with the wave, he immediately felt an extremely strong suction force, trying to suck all of his essence, Qi, and spirit dry.
Ha!
In the next moment, Bu Canghai shouted and swallowed several Soul Replenishing Pills. Suddenly, there was a surge of Spiritual Will surging out from his body, constantly confronting the fluctuations, and counteracting the strong suction transmitted by the fluctuations.
As he had guessed, this fluctuation was absorbing energy from the outside world, constantly maintaining its own operation.
"Again!"
Waves of Spiritual Will were constantly stimulated from Bu Canghai's body, and nine consecutive Spiritual Waves and nine strands of Soul Power came out of his body, counteracting the suction derived from the fluctuations.
Buzz!
However, at this moment, he realized that he had still underestimated this strange fluctuation. He did not expect that the seemingly invisible fluctuations contained the suction contained, beyond his imagination.
Even though he had unleashed nine psychic attacks, the suction force still erupted like a raging tide.
The originally calm fluctuations were completely detonated by his attack.
"Soul Concealment Kill!"
Facing such fluctuations, Bu Canghai erupted his strongest attack in the face of danger.
The void rippled, and this was his strongest attack in his current cultivation state. His Battle Qi surged, and his Blood Qi was like a tide. Together with his Soul Concealment talent, he did not hold back at all, and attacked the surging waves of fluctuations.
Boom!
There was a rumbling sound, and the originally faint suction force actually turned into a substantial tsunami, sweeping up boundless giant waves. In an instant, it swallowed his attack, decomposing it into the most primitive energy.
"This …!"
This made Bu Canghai's expression extremely ugly. His attack had all turned into the operation energy of the mysterious formation, so what could he do?
"Oh no!"
However, at this moment, he couldn't care about anything else, because the rolling waves were trying to devour him. The waves that seemed to have materialized were now five-colored. There were crystals flowing within them, and they were like waves crashing down.
Vaguely, he discovered that behind the waves, there was a silver-white vortex that was several feet wide, and there was a flash of green in it, which seemed to be a door.
"This is …!"
Naturally, he was very clear about the scene of the door behind the waves. It seemed to be a passage into a space, which existed in the Gu Yuan Tribe, so he was not unfamiliar with it.
"A secret realm!"
Bu Canghai exclaimed. It turned out to be a passage into a secret realm. Could it be that the fluctuations were constantly absorbing energy from the outside world to maintain the operation of the secret realm in front of him?
Buzz!
An extremely strong suction swept Bu Canghai into the silver-white door behind him.
