The huge snake looked up at the huge palm that covered the sky, and its body seemed to tremble slightly, but it didn't have any intention of dodging, it actually roared again, and suddenly the temperature of the entire hall rose rapidly again.

Then, the two heads of the Teng Snake suddenly merged together, and almost simultaneously opened its huge mouth, and suddenly saw two golden rays of light suddenly appear in the mouth of the Teng Snake, and then, with its head trembling slightly, the two golden lights blasted towards the huge palm that rushed in mid-air at the same time.

"Boom-"

The two attacks collided together in mid-air, and the power that erupted in an instant directly lifted all the jade on the floor of the main hall.

And after the golden pillar of light spewed out by the Teng Snake shook in mid-air, it instantly shot back, accompanied by the huge light blue chief, and at the same time fell fiercely on the Teng Snake.

In an instant, the entire hall shook violently again.

After a long time, the two rays of light in mid-air slowly dimmed at the same time, and then disappeared into the air, and then, the figure of a man, a beast and a Dannu appeared in mid-air again.

Xiao Bai manipulated the spirit pill slave and fell in front of Du Fei, with a vigilant face.

But Du Fei's face was extremely pale, the corners of his mouth twitched slightly, and his body moved, and he had already spurted out a mouthful of blood with a "wow".

"Whew-"

Seeing Du Fei spurting blood, the Teng Snake that was frozen on the ground suddenly let out a strange roar, like a punctured balloon.

Its body trembled on the ground, as if it was ready to pounce and swallow the small insect in front of it.

However, at the moment when it shook, there was a sudden rattling sound on the skin that was originally covered with iron-like scales, and then, the scales that were originally extremely strong were now shattered one by one, and immediately fell off the body of the snake like minced meat.

At this moment, the Teng Snake, which was about to lock the action, seemed to feel that something was wrong, it turned its head slightly, glanced at its body, and happened to see the scene where the scales were constantly falling off. This scene suddenly made the snake's expression seem to become extremely strange, as if it didn't believe that its body would have such a change.

However, before it could react, all the scales on its body had already fallen off, and the steaming hot flesh slowly turned black the moment the scales disappeared.

The black continued to spread, causing the flames on the Tenten Snake to dim in an instant, and in the end, all of them disappeared, and by the time the black had covered the Teng Snake, its body had returned into an incomparably delicate sculpture.

The entire hall suddenly fell silent.

At this moment, all the firelight in the hall disappeared, leaving only the pale red jade around it, shining brightly on the entire hall. And just now, at the position of the platform in the middle of the main hall, a dark hole suddenly opened above it, as if, at this moment, the mechanism was opened again.

Du Fei's figure stood in mid-air and watched the scene in front of him, his gaze did not fall on the hole that appeared, but on the Teng Snake that was completely petrified at this moment.

"What's going on?" After taking a slow breath, Du Fei said in a deep voice.

"This Teng Snake doesn't seem to be real, but after it was killed, its soul was sealed in the fossil, forming a ban!

"Actually using fossils to set up a ban ......" Du Fei frowned slightly, and a strange feeling surged in his heart. If it is said that the things in this are the inheritance of the ancient royal family, then this kind of arrangement is too elaborate, and the handwriting is inevitably too large! Not to mention, the piece of fossil just now is obviously a priceless thing. And this kind of thing actually exists only for the purpose of arranging a mechanism ban?

After all, Du Fei could also see clearly that after the appearance of the Teng snake just now, the huge fossil-making energy could be said to have been used up, that is to say, the great benefits he imagined were gone. And the price he paid to defeat that thing is not insignificant.

"Whew-"

After thinking for a while, Du Fei slowly took out a few pills and stuffed them into his mouth, slowly swallowed them, and while recovering his true qi, his eyes also fell on the cracked hole at the top of the main hall, in which, he could vaguely sense a bit of strange cold air gushing out.

After a while, Du Fei stretched out his finger and tapped it lightly at the center of his eyebrows, but he immediately frowned again, and said in a deep voice: "Isn't there a way for spiritual power to spread in...... This place is really unusual!"

"Master, I can't peep into this hole, and I always feel that it's too dangerous in there! You see, even the things that guard the door are so strong, so what will be in there?" Xiao Bai also jumped back on Du Fei's shoulder at this time, and said in a deep voice.

"Whatever it is, you have to go up and have a look, but you have to be prepared. Du Fei thought for a moment and said lightly.

He wasn't going to stay in such a place for too long, so after hesitating for a moment, he sat down cross-legged in mid-air, swallowed a few more pills, and recuperated silently.

After a while, after the power of the backlash was eliminated just now because of the use of the Nine Emperors Sealing Heavenly Hand, Du Fei stood up again, this time, considering that the spiritual power on it was useless, Du Fei first put away the spirit pill slave, patted the little tiger in his arms, and then jumped lightly and rushed towards the hole in mid-air.

Du Fei's movements were extremely slow, after all, he didn't know if there were any amazing prohibitions in this mysterious ancient altar at this moment. It's just that although he moved slowly, he didn't receive any attacks until he floated to the second floor of the main hall.

The setting of the second floor hall is not much different from the setting of the first floor hall, but the area seems to be one-third smaller. The whole hall was empty, except for a stone platform in the depths.

Du Fei's gaze swept around for a moment before he slowly walked towards the stone platform.

The stone platform was about a meter high, as if it had been carved directly into the floor, and there was nothing strange on it, just a blank space.

Du Fei stared at this stone platform, and he didn't know what was hidden on this thing for a while, but this second-layer hall thought that there was nothing else except this thing, so there seemed to be no other way than to look at it.

After looking at it for a while, Xiao Bai on Du Fei's shoulder suddenly hesitated: "Master, this may be a mechanism formed by using true qi in ancient times, and it needs true qi to be able to open it, you might as well try it." ”

Hearing this, Du Fei nodded slowly, and after hesitating for a moment, he had already reached out and pressed on the stone platform.

"Boom-"

At the moment when Du Fei's palm was implemented, there was a sudden shock all over his body, and he immediately sensed that there seemed to be some kind of strange suction on this stone platform, constantly sucking away the true qi in his body, and this kind of suction power was extremely violent, if it weren't for Du Fei's true qi being several times richer than that of an ordinary half-step martial arts peak realm powerhouse, I am afraid that under a single appearance, he would be sucked dry by this strange stone platform.

With a muffled snort, Du Fei's palm shook violently, and he wanted to get out of this stone platform first, but under the shock, his face changed suddenly, because the adsorption force on this stone platform seemed to be a little sticky, no matter how hard he tried, he was always unable to pull the palm back.

In the next moment, Du Fei's face changed drastically!

Quickly took out a handful of Hui Qi Pill and stuffed it into his mouth, Du Fei was relieved, and then his face changed: "Xiaobai, hurry up and find a way, don't wait for the Teng Snake to help us, but we are hanging in the hands of this inexplicable stone platform." ”

"This..." Xiao Bai's face was also extremely ugly, it cautiously jumped onto the stone platform, and after groping for a while, it suddenly showed a somewhat ugly expression, and hesitated: "Master, I seem to understand the key to this mechanism." ”

"What do you say?" Du Fei frowned.

"This mechanism looks weird and unpredictable, but it is extremely simple to crack, as long as there is enough true qi to penetrate it and let it eat to its full, then the master can not only untie the shackles, but also, this second-layer mechanism is basically unlocked!" Xiao Bai said in a deep voice.

"Let it eat all-you-can-eat?" Hearing this, Du Fei's face twitched slightly, who knows what the capacity of this stone platform is, although he has a deep foundation, but he can't be constantly sucked like this!

"Of course, you don't have to have true qi to be able to feed it, as long as you have enough energy, no matter which one it is, you can feed it. Seeing Du Fei's face change, Xiao Bai hurriedly explained.

"In other words, the pill is okay?" Hearing this, Du Fei's face changed slightly, but he was not an ordinary person after all, after gritting his teeth slightly, his left hand had been gently shaken, and he suddenly saw the pill in his black spirit ring flying out quickly, as if he didn't want money, and it hit the stone platform in front of him.

"Boom, boom—"

Under Du Fei's distressed eyes, all those miscellaneous pills had been beaten into the stone platform by him, and soon, he gritted his teeth and shook his hand, but this time, a large number of Yanzong Dan were quickly beaten into the stone platform in front of him.

However, with the entry of Yanzong Dan, Du Fei's face became more and more ugly, the capacity of this stone platform seemed to be endless, and it could easily enter the Yanzong Dan of a strong man into its body, as if it had entered a bottomless pit, and there was no edge in sight. If it weren't for the fact that the stone platform had become less powerful in absorbing Du Fei's true qi after it was injected with the elixir, he would have almost thought that Xiao Bai was cheating on himself.

Du Fei gritted his teeth and smashed the Yanzong Pill into it, and after almost 80,000 Yanzong Dan were punched, the stone platform finally shook slightly, and then the adsorption force that absorbed Du Fei's hand slowly disappeared.

Then, a milky white light suddenly emanated from the stone platform, and a dull sound came from the overhead.

Du Fei slowly raised his head, and saw that in the center of the second-floor hall, the stone slab above his head was also slowly retreating in a low voice, and then another stone cave was revealed.

And almost at the same time as this stone cave appeared, it seemed that a cold air instantly diffused from inside, directly causing this ancient altar, which was originally still a little hot, to instantly turn into a cold.

In this ancient altar that seemed to be made of flames, there was still such an extremely cold place, and at this moment, even Du Fei showed a little surprise.

It's just that in this world, Du Fei is the least afraid of the cold, if there is really anything extremely cold in it, then for Du Fei's cultivation exercises, it is definitely a great supplement, so no matter what is in the hall of the third layer, for Du Fei, this trip can be regarded as worth it!

Laughing slowly, Du Fei didn't say any nonsense, but stepped on the soles of his feet, and his body had already rushed towards the third layer.
