After studying for a while, Li Fei unexpectedly found that this was an ordinary stone door, and there were no prohibitions, but the stone gate was extremely thick, and the preliminary estimate reached several zhang thick.

In fact, Shimen had a ban before this, but the ban was not strong, and it was mainly composed of a phantom array to prevent anyone from discovering it. After the Antarctic ice dragon stirred up, there was nothing left for a long time.

Since there was no prohibition, Li Fei naturally enjoyed it, collected the Antarctic Ice Dragon, took out a talisman, slapped it on his body, and easily passed through the stone gate and came to the other side of the stone gate.

On the other side of the stone gate, there was still a narrow passage, and the sea water in it was also flowing, so Li Fei did not stop for long, and continued to explore along the passage, and then went down.

After a small half of the incense, Li Fei's face froze and stopped. After observing for a while, Li Fei summoned the Antarctic Ice Dragon again.

This time, because of the small space, the Antarctic Ice Dragon did not perform the previous dragon whirlpool move, but opened its blood basin mouth, sucked hard, and instantly cleaned up the seawater in the passage, and then sprayed out an ice mist, freezing the passage wall and preventing the seawater from continuing to pour in.

Li Fei praised the Antarctic Ice Dragon, and no longer took it back, so he let it follow, and then came to the green jade gate to take a look.

As soon as he touched the ancient jade gate with his hand, a scorching heat came, and Li Fei's hand was bounced away. Li Fei was greatly surprised, he didn't expect that this jade gate was very different from the stone gate in front of him, as if there was a fire locked inside.

Before Li Fei could study further, the Antarctic Ice Dragon showed a hint of fear and took the initiative to go back and continue to sleep. Li Fei's heart moved, put away the Antarctic Ice Dragon, and then summoned the fire spirit out to prevent accidents.

As soon as the fire spirit came out, he didn't let Li Fei greet him, and took the initiative to stick to the jade gate, and then it swelled and turned into a huge flame, covering all the jade gates that were several zhang large!

Half an hour later, the fire spirit escaped directly into the jade gate. Li Fei showed a hint of a smile, and without much effort, he opened the jade gate and entered a world of fire. After a soft sound, the jade gate returned to its original state.

At this time, the fire spirit had already fought with several strange figures! With the help of magma, the fire spirit's strength had at least doubled, but it was still obviously at a disadvantage!

Li Fei took advantage of the fact that he had nothing to trouble for the time being, and began to look at these strange enemies in front of him.

The three humanoid creatures, nine feet tall, looked extremely strong, covered in blood red, not only fearless of the extremely hot magma, but also had a foot-high flame on the surface of their bodies.

"What kind of monster is this?" Li Fei felt a little impressed, but for a while, he couldn't remember it.

But now there is no time for Li Fei to think slowly, after all, the fire spirit has been beaten by the three monsters and has no power to fight back, so he can only take down the other party first.

After a rough observation, Li Fei had already estimated the strength of the three monsters, which should be comparable to that of ordinary late-stage cultivators. Of course, it is necessary to exclude the special environment here, if it is this extremely hot environment, not to mention the late stage of the three Yudan, even six are not opponents.

Although Li Fei is still relatively confident in his own strength now, the monsters that appear in this extreme environment dare not be underestimated at all.

With a flick of his hand, the broken bowl engraved "Upside Down" had already appeared in Li Fei's hand, and then he pinched it with both hands and sacrificed it, a layer of faint brilliance shrouded the square for several zhang, and there were countless fist-sized silver runes on the surface of the light curtain slowly circulating.

With the protection of "turning the world upside down", Li Fei's expression eased, and the cloud sea sword flowed with a burst of black light, rising against the wind, and instantly turned into a giant sword seven or eight zhang long, slashing towards one of the monsters.

The monster let out a strange laugh, gave up the siege of the fire spirit, reached out and grabbed it in the rock general, held up a large cloud of magma, and faced the cloud sea sword.

At the moment when the two sides came into contact, the Yunhai Sword spewed out a stream of gray sword qi, engulfing the monster into it!

With a "plop", the monster was temporarily landed in the magma, but soon, the monster rushed out unscathed, carrying a large stream of magma, forming a magma flow, and rushed towards Li Fei!

Li Fei was surprised, he didn't expect the monster's defense to be so strong, and it was directly hit by the Yunhai Sword, and there was nothing wrong at all!

With Li Fei's current strength, he will go all out, not to mention the monks in the late stage of the Jiedan, even the masters of the Great Perfection in the late stage of the Jiedan, it is absolutely impossible to ignore it, but I didn't expect that monster to be so powerful that it is invulnerable! Li Fei's expression became solemn again.

Li Fei withdrew the Yunhai Sword, and the eleventh layer of the Life-Seeking Sword Thunder had already struck.

"Boom!" There was a loud bang, and a large area of magma was blown up all over the sky, but the monster was nowhere to be seen. Li Fei was shocked, and without hesitation, he performed Ling Bo's extreme movement, and instantly appeared on the only rock dozens of zhang away. But Li Fei was not steady, but hung a few feet in the air.

Sure enough, as soon as Li Fei left, the monster silently rushed out of the magma and rushed straight to the place where Li Fei was standing just now, and the result naturally failed.

On the other side, because of the lack of one monster, the pressure of the fire spirit was reduced a lot, and he fought with the two monsters, constantly going in and out of the magma pool, and had a lot of fun.

The monster that swooped into the air once again dived into the lava pool and lost its sight. Li Fei suddenly remembered the scene of subduing the fire spirit, and his heart moved, so he simply stopped making a move, and suspended in the middle of the rock, waiting for the monster to send it to the door by itself.

After a while, sure enough, another large stream of magma flowed towards Li Fei, and Li Fei once again sent out a life-seeking sword thunder and blasted towards him.

As a result, before the magma flow could be dispersed, the monster had already pounced from behind Li Fei. Li Fei held the Yunhai Sword in his hand, sneered, and suddenly urged the power of "turning the world upside down" to the extreme, instantly enveloping all the rocks in a radius of more than ten zhang.

At this time, the monster had already broken into the white light curtain, and its body was stagnant, and it landed on the rock, but it did not completely lose its combat effectiveness, but bent its legs, jumped forward, and continued to pounce on Li Fei.

Li Fei was a little surprised, but he didn't care, the Yunhai Sword slashed out with lightning and blasted the monster towards the rock wall! The monster that seemed to be still undamaged collided with the rock wall, and one of its arms actually fell off! But there was no blood or other liquid flowing out.

At this time, Li Fei finally knew why the monster seemed so fierce before, in fact, it was not so powerful, but the monster was in the magma and could recover quickly.

Taking advantage of the monster being forced to the edge of the rock wall, Li Fei naturally would not let go of such a good opportunity, and the life-seeking sword and thunder bombarded again! The monster was finally blown into two sections, although it was still squirming, but there was no longer a threat.

Li Fei approached the monster, picked off the mask with his sword, looked at it carefully, and found that it was really the face of a monk. But it's not a living person, it's a fire-refined corpse that has been refined with a special method!

The formation of a fire refining corpse can be said to be very difficult, and at the same time, it is extremely cruel! A fire refining corpse of this level just now must have cultivated the fire attribute technique during his lifetime, and his cultivation has reached at least the late stage of the knot, but I don't know what reason it was, it was refined alive.

In order to maintain strong combat effectiveness, the refined monk has been erased before death, and then uses special methods to imprison the soul, and after the corpse has undergone a series of treatments, the soul is beaten into the body that has been refined, thus becoming one of the most powerful refining corpses.

In addition to the fact that it is impossible for the fire refining corpse to grow in the cultivation realm, in this kind of extremely hot land, it almost has an immortal body, unless it is blasted into slag at one time, it will be able to recover its combat effectiveness after a while.

It can be said that the fire refining corpse is a more practical existence than a puppet. Because ordinary high-level puppets need chance and time to grow, and as long as there is a suitable candidate for the fire refining corpse, it will not take long to refine it. Especially in this special environment, it doesn't take long for ordinary puppets to break, but fire refining corpses don't.

Of course, the cruel method of refining corpses by fire, not to mention that there were very few monks who knew about it before, even if some people knew about it, they would not generally carry it out.

After thinking about it for a moment, Li Fei threw dozens of forbidden hands to imprison the fire refining corpse, and then threw it into the magma, slowly connecting its disconnected body again. After feeling that it was almost over, Li Fei pulled up the fire refining corpse, took out a spirit beast bag, and packed it up.

After Li Fei dealt with this fire refining corpse, he found that the fire spirit and the two fire refining corpses didn't know where they had gone, so he decided to ignore them for the time being and explore this space first.

This space is irregular, zigzag, large in some places, small in others, and there are many forks in the road. After some searching, Li Fei finally found a special place.

It was a rock crack far away from the magma, only a few feet wide, and after a few turns, the temperature had dropped a lot, and there were obvious artificial traces around it.

It didn't take long for Li Fei to come to an end. The result was that Li Fei was shocked, it turned out to be a small tomb, with a jade tablet erected on each side, and the inscription: Far away in the sky, close in front of you.

Li Fei is in a good temper, and found that it took a long time to find that it was the result, and in anger, he sent out a life-seeking sword thunder, which happened to slash at the grave.

The seemingly inconspicuous grave suddenly flashed with white light, and after a burst of streamers, it was easy to block the powerful life-seeking sword thunder!

Li Fei suddenly became interested, and attacked more than ten times in a row, only to find that he couldn't shake it at all. Just as Li Fei was thinking about how to make his next move, the fire spirit suddenly rushed in! Behind it, more than ten fire refining corpses were roaring all the way in, and they were holding a large cloud of red magma one by one!

Li Fei was so angry that he wanted to pinch the fire spirit to death immediately! He scolded: "You didn't come early, you didn't come late, and now you have brought a lot of enemies to this dead end, and you really killed you......"
