The prohibition at the entrance of this ancient altar is exactly the same as the prohibition outside, which seems to indicate the relationship between this place and the ancient royal family.

After staring at the prohibition silently for a moment, Du Fei did not break the blood and unseal, but hesitated for a moment before saying lightly: "Come on!"

"Boom-"

After Du Fei took a few steps back, the spirit pill nu had already stepped forward, and immediately blasted out with a punch, and then heard a loud bang, and suddenly the prohibition at the door trembled slightly, and instantly exploded into pieces of light, revealing the swarthy hole inside. Obviously, although the prohibition here is the same as the outside, it is not as huge as the outside, so relying on the brute force of the Lingdanu, the prohibition here can be directly broken.

"Master......" Xiao Bai, who was standing on the shoulder of the Lingdannu, glanced back at Du Fei and said in a low voice.

Du Fei nodded slowly, and after thinking for a while, he picked up Xiaohu and put him in the arms of the Lingdanu, and then he took a light breath and walked towards the door of the ancient altar.

In the door, there was a faint red light that flickered continuously, making Du Fei feel a faint sense of heat the moment he walked in. Sensing this feeling, Du Fei's mind had already moved slightly, and he instantly urged the Ice Lotus Pill in his body, and then, his feelings returned to normal.

After doing all this, Du Fei nodded, and immediately walked into the doorway.

"Whew-"

The moment he entered the Ancient Altar, an extremely hot aura suddenly came to his face, but this time, this breath had no effect on Du Fei. He just squinted slightly, and then his gaze swept around.

In this ancient altar, there is an extremely huge hall, just a simple height, dozens of meters high. The whole hall is in a circular shape, and the walls inside are the same as those outside, made of pale red jade. It's just that so many jade stones are piled up together, but it seems that it is not just jade, but pieces of flame piled together.

Although Du Fei hadn't recognized what these red jades were at this moment, if there were no accidents, these jades might be priceless and rare. It's just that so many jade stones have been piled up together, but there is an extremely surging atmosphere in it, so that Du Fei doesn't dare to use these things at will.

After sweeping his gaze, Du Fei's gaze swept to the middle of the main hall, where there seemed to be a platform, and above that platform, there seemed to be bursts of hot fluctuations constantly diffusing out. It was as if the hot breath came from above the platform when I first entered this place just now.

After squinting at that place for a moment, Du Fei had already activated the Ice Lotus Pill Qi in his body again, and then walked slowly towards that place.

The closer I got to the platform, the more the air around me seemed to get hotter, as if a person was in a furnace. Although this kind of heat had no effect on Du Fei at this moment, the little tiger who was shrunk in the arms of the elixir behind him let out a burst of uneasy roars at this moment.

Du Fei glanced back at the indifferent Lingdanu behind him, and after hesitating for a moment, he had already sent out a stream of true qi to wrap around Lingdannu's body.

After doing this action, Du Fei continued to sound slowly, and this time, when he walked directly to the bottom of the stone platform, he wrinkled slightly, and immediately stopped.

At this moment, the strange stone platform had all appeared in front of Du Fei's eyes, so he could see it clearly, at this moment, the stone platform was not flat, but carved with some extremely strange lines, these lines continued to circle and spread, and in the end almost circled around this platform.

"Is this an ancient monster totem?"

After the figure slowly circled around the platform, Du Fei was sure that the carvings around the entire platform were obviously integrated, and the carving style of the carvings was extremely realistic, almost making people mistakenly believe that some demon beast was hovering here.

It's just that, judging from the carved shape of this demon beast, its appearance is no different from that of a snake, except that it has a pair of huge fleshy wings on its body. Moreover, the place where its head is carved is like the legendary ancient dragon. However, this is not the weird place, the most weird thing is that this demon beast, it seems that at the beginning and the end, each has a head, if it weren't for the huge flesh wings to help determine the direction, it would almost be impossible to tell which side is the head and which side is the tail.

The most strange thing is that although this carving is a dead thing, from above it, there is a faint smell of slaughter, as if it can infect people's minds. If it weren't for the Ice Lotus Pill in Du Fei's body, even he might not be able to guarantee that he would be able to maintain absolute calm under such an infection.

"Whew-"

After taking a slow breath and squinting his eyes slightly for a moment, Du Fei stepped forward again, and immediately stepped on the body carved by the strange monster, and then stepped on the stone platform located in the middle of the main hall.

On the stone platform, Du Fei finally saw clearly what appeared in front of his eyes at this moment.

It was a giant egg-like hedron with a red body, and there were waves of hot fluctuations that diffused out of it, and they spread out to the outside world in bursts. At this moment, if ordinary people are here, I am afraid that under this fluctuation, they will suddenly turn into ashes. And even if an ordinary half-step Martial Sect peak realm powerhouse is here, I'm afraid it won't be able to hold on for a while.

Only Du Fei, who was an exception with the Ice Lotus Pill, could stand here as if he was nothing.

After staring at the hedron for a moment, Du Fei realized that the hedron was not stable, but as if the afterimage of something was constantly flowing inside, and the fiery fluctuations were caused by the flow of these afterimages.

After staring at this strange spar for a moment, Du Fei exhaled and muttered, "This... What the hell is it?"

At this moment, Xiao Bai had already manipulated the spirit pill to come to Du Fei's body, and after staring at the spar for a moment, Xiao Bai suddenly swallowed lightly, with a somewhat incredulous look, and said in a lost voice: "This is... Fossilization?"

"Fossil making?" Hearing this name, Rao Yi Du Fei's heart suddenly shook slightly. The name of fossilization may not have any feeling for ordinary powerhouses, but for Du Fei, who has obtained the inheritance of King Dan, it is very unusual.

According to the records in the ancient scrolls of King Dan, King Dan once obtained a prescription handed down from ancient times, which is called the Pill of Creation. According to the prescription, the effect of this Creation Pill is that no matter who takes it at any time, they can forcibly improve their martial arts cultivation to a higher level. For example, if you are a half-step Martial Sect Xiaocheng Realm powerhouse, but as soon as you take this Creation Pill, you may become a half-step Martial Sect Dacheng Realm in an instant! If this pill is placed in the eyes of those old monsters who have been stuck in a bottleneck for a long time, I am afraid that even if they pay any price, they will want to get here.

According to the records, the refining of this Creation Pill is extremely difficult, and its main ingredient, fossil making, is extremely difficult to obtain, which is basically something that can be encountered and cannot be found, but Du Fei couldn't imagine that the crimson spar that appeared in front of him at this moment turned out to be the legendary fossil creation!

Rao was with Du Fei's concentration, and at this moment, his heart was also hot, and his palm stretched out towards the front almost unconsciously.

By Du Fei's side, Xiaobai was still a little calm at the moment, but the moment he saw Du Fei stretching out his hand, he was also shocked, and said quickly: "Master, you can't do it!"

It's just that Xiao Bai spoke quickly, but Du Fei's natural movements were faster, as if some magic was controlling him. By the moment Du Fei reacted, his palm had already lightly pressed on top of the huge fossil.

In an instant, the heavy fluctuations that had originally diffused from the fossil created suddenly fell silent, and almost at the same time, the originally hot air around it instantly returned to normal, and then, all the pale red jade that originally emitted a faint light lost its light at the same time.

Then, I saw that the boundless darkness directly enveloped the entire hall.

Du Fei frowned slightly, tiptoed a little, and retreated to the rear without hesitation. At the moment of landing, the body tensed instantly.

At this moment, a bad premonition came to my heart.

In the next instant, the mutation had happened.

I saw that in the depths of this hall, suddenly there was a sharp roar, as if some kind of powerful demon beast had been awakened from its sleep.

Then, I saw that in the main hall, which had lost its light, on the platform in the middle, above the huge fossil, a strong red light once again appeared.

"Click, click—"

Almost the next moment when the red light appeared, cracks burst out on the fossil like a giant egg, and then, at a certain moment, those cracks trembled at the same time, and suddenly I saw pieces of rubble shooting out violently in all directions.

"Roar—"

In the crimson light, two scorching golden eyes lit up, and immediately a low roar came out of the red light, causing the entire hall to shake gently in an instant.

Immediately, Du Fei clearly saw that the surface of the stone platform, which was originally just a carving, had cracked into a Dao crack, and then, an ancient demon beast with an almost incredible body slowly appeared in his sight.

Du Fei's pupils contracted instantly, and almost without hesitation, his feet had floated backwards in an instant, and at this moment he had already determined that his unintentional action just now had touched the prohibition here, and the demon beast that he thought was carved turned out to be an ancient demon beast in a sleeping state!

The figure fell to the edge of the main hall, Du Fei's eyes were staring at the strange demon beast that was dancing in the hall at this moment, and after a while, a wry smile appeared at the corner of his mouth: "No wonder there is no mechanism prohibition along the way, it seems that this thing is the biggest mechanism." ”

"Xiaobai, you haven't figured it out yet, what is this thing?"

Hearing Du Fei's voice, Xiao Bai's face was slightly shocked, and after a while, he said with a little interference: "If I am not mistaken, this thing should be an ancient demon beast, Teng Snake!"

"Teng Snake!"

Hearing such a name, Rao Yi felt a dry hair in his mouth with Du Fei's calmness. He also knew a little bit about the name of this Teng snake, this kind of demon beast that was also famous in ancient times, he didn't expect it to appear in such a place.

And just between the two answers, the Teng Snake, which was originally just spreading its teeth and claws in mid-air, seemed to have discovered something, it stopped moving, and then slowly turned its head, and the strange gaze instantly fell on Du Fei's body.

At this moment, even Du Fei, the corners of his eyes twitched slightly.
