There was endless darkness under the pit, there was no sound, nothing could be seen with the naked eye, not even a gentle breeze, this was the world under the pit.

In the depths of the endless darkness, the space is extremely distorted, as if another invisible barrier blocks everything from outside. Originally, this place was extremely secretive, and even many extremely powerful people came to this area without being aware of the secrets here.

It's a pity that under a violent collision, a gap briefly appeared in this layer of space barrier, and it was such a small gap that produced an incomparably amazing huge suction force that sucked Sun Xiaofei into this space.

After Sun Xiaofei's body was sucked in, he hit some hard objects heavily and fell to the ground.

In this process, Sun Xiaofei didn't seem to have any sense, allowing his body to suffer this huge impact. Inside his sea of consciousness, some gray energy was eating away at his soul.

Sun Xiaofei's current soul has transformed into the body of the Yuan Baby, and although the body is out of control, the Yuan Infant is intact. In addition to the moment when he was attacked, Yuan Ying lost his mind for a short moment, and under the protection of Yuan Ying's autonomy, a dark blue armor immediately appeared on Yuan Ying's body surface.

This armor is the soul defense that Sun Xiaofei had cultivated before the formation of the Yuan Infant. When he is attacked, he will automatically defend himself. When Sun Xiaofei was eroded by gray energy, his head only lost his mind for a moment, and then he quickly regained consciousness, so that he could react immediately and resist the gray energy.

He fought against the gray energy with all his might, and when his mind was awake again, his body could not resist the huge suction force in the deep pit, and was sucked into the vortex.

After Sun Xiaofei's soul transformed into a Yuan Infant, he was already very powerful, and he was able to regain consciousness in such a short time.

In the sea of consciousness, Sun Xiaofei's inner and outer bindings were cast at the same time, and then the handprints changed, transformed into a treasure bottle seal, absorbed the gray energy inside, and refined it into strands of pure energy for his own use.

After absorbing these energies, Sun Xiaofei found that Yuanying actually had a very cold and comfortable feeling, and he realized that this gray energy was of great help to his Yuanying. couldn't help but be overjoyed, and suddenly forgot the danger of being in danger, desperately speeding up to absorb it, in less than a moment, the gray energy around him who tried to erode him was absorbed by him, after absorbing these gray energy, Sun Xiaofei felt that Yuanying's body had undergone some changes, and these changes were a good thing for him.

Sun Xiaofei's eyes opened suddenly, and he glanced around casually, not noticing any danger around him. He got up and checked his body, only to get some abrasions, his physical strength was not weaker than some demonic beasts, and to his delight, the mana that had just disappeared had actually returned. With mana, he at least had some ability to protect himself in this dangerous and unfamiliar environment.

Sun Xiaofei saw that the place he was in now was a dim and dull cave, and the surrounding scenery was a little blurry, which was not difficult for him, even if the cave was as dark as ink, he could see everything around him clearly.

Sun Xiaofei pondered for a while, chose a direction, and his divine sense slowly spread out, extending into the distance, Sun Xiaofei began to explore the environment and terrain here.

The terrain was a bit complicated, full of various passages and caves, and his current location was in one of these caves where he couldn't see the exact number of them.

Sun Xiaofei observed the surroundings as he walked, and the road here turned around like a huge beehive, making it impossible to discern which road was the real way out.

Sun Xiaofei was not discouraged, he walked carefully in the cave, his divine sense was scattered within a range of hundreds of meters around him, and he was always vigilant of all dangers around him.

I don't know how long he walked, but he always walked around the cave, and it seemed that there was no real way out here. Sun Xiaofei frowned and walked aimlessly, but he was constantly thinking about how to get out of here.

Suddenly, Sun Xiaofei heard a hint of movement, he stopped and listened carefully for a while, with a smile on his face. When he explored this place, he didn't encounter some dangers, but he easily defused them. These attack facilities should have been left behind by the people who lived in the ancient city before.

Walking and walking, he entered a cave, and when he saw the cave in front of him, Sun Xiaofei shook his head, he returned to the place where he had made the mark, and looked at it silently for a while, and the doubts in his heart already had some vague answers.

According to Sun Xiaofei's conjecture, the place where he was should be an ancient formation, specially used to trap the people who broke into it. It stands to reason that there will be some facilities to attack the enemy in the formation, I don't know why there is no movement, he has walked for so long, and he has not encountered much danger, presumably there are some mechanisms in the formation, because of the age, they have long been damaged and have lost their effectiveness.

Unexpectedly knowing that he was trapped in the formation, Sun Xiaofei immediately calmed down and began to carefully study this formation. If he wants to leave here, he must first crack the formation here, and if he doesn't understand the mystery and law of this formation, it will naturally not be so easy to get out.

Sun Xiaofei's previous life was originally to study the way of the Fu Seal, and the so-called magic arrays and forbidden techniques on this continent are all similar to the formations. Sun Xiaofei combined his own experience and the knowledge he had learned in the Holy Dragon Academy, and it took him a few days to finally find a way to crack the formation and get out of here.

Half an hour later, he stepped out of this formation, which had the effect of confusing and imprisoning the enemy. In front of him, there was the exit of the formation, Sun Xiaofei glanced behind him, and then strode away.

The owner of the ancient city of Byron has always been the target of the great empires. After several studies and discussions, the powerhouses of various empires have unanimously agreed on the confirmation of the identity of the owner of this ancient city.

Byron, the city's former city lord, was an extremely powerful Saint-Order powerhouse, proficient in various ancient sealing techniques and forbidden techniques. In those days, few people dared to provoke him.

From the fact that after his death, he was able to use his great magical powers to seal the entire city for so many years, which shows his amazing mastery of sealing and forbidden arts.

Sun Xiaofei's entry is the burial place of this legendary figure. On the walls on both sides of the passage, the deeds of Byron's life are depicted, and Sun Xiaofei walked all the way, like a conversation between his heart and the legendary Byron, so that he could understand more and more about Byron.

The more Sun Xiaofei knew, the more shocked he was in his heart, and he was impressed by Byron's personal talent. Byron, the most outstanding master of formations and forbidden arts, has studied countless formations in his life, thus establishing this world-famous ancient city of Byron.

In this ancient city, various formations were arranged everywhere, some trapped enemies, some confused, and many powerful attack formations, large and small, distributed in the city no less than thousands, so that all the enemies who wanted to occupy the ancient city of Byron had to pay a heavy price, and even could not escape safely.

Formations and forbidden techniques are the basis for Byron's fame, and the ancient city of Byron is a place that has been carefully arranged and operated by him for many years, and many places, even the top powerhouses of the four empires dare not easily enter and try.

After Byron's death, in order to preserve everything he had, he sealed the entire ancient city and sank it into the ground, so that neither the world nor his enemies could find his location.

What he learned in his life was engraved in the deepest palace underneath, Sun Xiaofei entered the palace, looked at the text on the wall that recorded Byron's life and deeds, and knew that he was there now.

This palace is the tomb where Byron was buried after his death.

On the palace, huge columns stand everywhere, on which are depicted various formations researched by Byron himself, and on the walls there are records of how to learn formations and forbidden techniques.

According to the level of level, it is divided into entry-level, summit level and master level. The entry-level wall records the knowledge and brief description of the basic formation. On the walls of the summit level, advanced formation and forbidden art knowledge are recorded, and there is a complete set of learning methods.

As for the other wall, there were many more esoteric formations and forbidden techniques recorded, which were not something that Sun Xiaofei could learn now.

Sun Xiaofei turned his eyes and looked up to see a crystal coffin suspended at the top of the palace. This crystal coffin is turquoise blue, it looks very beautiful and moving, the whole crystal coffin is carved with many esoteric patterns, the four corners are inlaid with the best spars that emit a soft light, and the four black chains pull up the crystal coffin, and the top of the palace is a strange pattern, forming a sense of harmony and integrity.

"I am Byron, the ancient formation master, who has studied the way of formation forbidden techniques all my life, built an ancient city here, and left the way of formation forbidden techniques that I learned in my life, and taught them to people who are destined. Those who can enter this hall are my disciples, and they should perform the rites of master and apprentice, pass on the knowledge of a formation, and reproduce the prestige of my Dao. ”

On one side of the crystal coffin, there are several lines of striking text, which are all ancient scripts. Fortunately, Sun Xiaofei had already studied this, and in the academy, he learned many ancient characters, so that he could see at a glance what the content of the text written on it was.

Sun Xiaofei could see that there was a corpse lying in the crystal coffin, this corpse was the appearance of a man, and this man was Byron, the owner of the ancient city.

Sun Xiaofeiyao bowed to the crystal coffin. He whispered in his mouth: "Senior, I, Sun Xiaofei, swear here, that I will definitely fulfill your wish well and carry forward your formation learning." ”

Sun Xiaofei has already decided not to leave here in a hurry, the seal of the ancient city has now been restored, he wants to stay and learn Byron's formation and forbidden arts, and after he has mastered these abilities, he will consider leaving. Since then, Sun Xiaofei has worked hard to cultivate in the palace, and devoted himself to learning the formations and forbidden techniques left by Byron.
