It lasted for about half an hour, and countless points of light began to operate in a vortex-like form, generating a huge suction, and as time passed, the ball of light that Li Fei Yuanying was living in had completely turned into an entity, and suddenly appeared in the center of the vortex with a wonderful trajectory!

At this moment, a clear understanding rose in Li Fei's heart, and the bottleneck of the middle stage of the Boundary Formation broke through silently, reaching the late stage of the Boundary Formation! With the support of a large number of top-grade pseudo-immortal crystals, Li Fei's cultivation rose all the way, directly rushing towards the peak of the late stage of the Boundary Formation!

An hour later, Li Fei had easily reached the peak of the late stage of Realm Formation! Although he could no longer absorb the top-grade pseudo-immortal crystal to improve his cultivation, the realm that had just become a great achievement was only a newborn baby, and he was in need of a lot of supplements, so he was still absorbing it with all his might!

With the countless top-grade pseudo-immortal crystals turned into powder, the world in Li Fei's body is undergoing earth-shaking changes, first of all, the core ball, the volume has skyrocketed by more than 100 times, from more than half a zhang of the original, to nearly 100 zhang, and initially has the prototype of the planet, and countless points of light, like seeds, slowly began to condense, and finally turned into the size of a table tennis ball!

After the condensation of countless points of light, Li Fei's speed of absorbing pseudo-immortal crystals suddenly slowed down! In fact, it wasn't really slow, but that the energy needed was too much, and it was in short supply at all!

After another moment of incense, with a huge explosion, the entire "Battle Demon Array" suddenly collapsed! However, the explosion was not outward, but collapsed! Xiang Cheng and the others were trying to collect it, and when something suddenly happened, they were all taken aback and fled one after another.

Soon, everyone discovered Li Fei's abnormality, and they were all surprised and happy! Because Li Fei at this time, although it was right in front of everyone's eyes, their divine thoughts couldn't sense his existence, and they inexplicably felt that the current Li Fei seemed to have become an invincible existence!

Because what they are facing is no longer a person, but a starry sky, and how can they overcome it in the face of a starry sky? This is beyond their cognition, it is a completely new field!

"Husband, you're not going to directly advance to the Realm Transformation Stage, do you, I feel like you're completely different from us!"

After about a stick of incense, Li Fei finally showed a happy smile, opened his eyes, looked at his friends, and said happily: "The Transformation Realm? ”

Xiang Cheng stared at Li Fei closely, and said after a while: "Boss, in the late stage of your advanced realm, I estimate that the difficulty is no less than that of the ordinary cultivator's advanced realm stage! If I am not mistaken, your current strength is probably far more than that of the previous wasteland demon saint!"

Li Fei said cautiously: "It has not been tested in actual combat, this is not easy to say." But one thing is for sure, if I were to face that wasteland demon saint now, I should be able to defeat him. ”

Hua'er saw that Li Fei's strength had improved by leaps and bounds, and said eagerly: "Now that Fujun's strength has risen sharply, shouldn't we rush back and return after everyone has improved their strength again?"

Thinking of the change of "Xiaoqiang" and the change of the "Battle Demon Array", Li Fei was very uneasy in his heart, shook his head and said: "Don't stay any longer, although this 'Battle Demon Array' is destroyed, a considerable part of the remaining pseudo-immortal crystals can at least be used as high-grade pseudo-immortal crystals, which is also a huge wealth, everyone hurry up and put it away, so as not to have too many dreams at night!"

The "Battle Demon Array" that had collapsed was no longer difficult to collect, and in just a moment, Xiang Cheng and the others collected it all, and everyone got hundreds of millions of pseudo-immortal crystals, and happily rushed out with Li Fei.

As soon as he returned to the stone peak, Li Fei subconsciously let out a sweep, then let out a strange scream, waved his big hand, and seemed to take Xiang Cheng and the others into his sleeve, and then struggled to tear open the void, submerged into it, and disappeared without a trace.

It turned out that Li Fei had just swept it with his divine thoughts, and found that dozens of extremely powerful and extremely powerful breaths were coming out of the void hundreds of miles away, and the weakest one of them was a hundred times stronger than that wasteland demon saint! One of the golden-robed men was even more unfathomable, and Li Fei was almost distracted when he glanced at him!

If Li Fei's strength didn't have this leap, he could be sure that there was absolutely no chance of being spared, the strength of that person trapped by that person had completely surpassed the level of the Transformation Domain, and even if he reacted quickly, he was also glad that he had just had the ability to tear apart this Demon Domain battlefield and could break through the air.

Of course, there is also a very critical point, Li Fei is now in the realm of completion, and he is no longer limited to the storage space, he can use the "realm" of the beginning of the formation to directly include Xiang Cheng and others in his own "small world", unless he falls, no one else can hurt Xiang Cheng and the others at all.

Otherwise, if he alone could withstand the spatial pressure of the Demon Domain Battlefield, Xiang Cheng and the others would be torn to pieces by the powerful space storm even if they entered.

As soon as the space was closed, that group of peerless powerhouses came to the place where Li Fei had just stood, it turned out that they had used teleportation to cross hundreds of miles! This kind of ability was no longer something that a master of the Transformation Domain could do, and they had so many people arriving at the same time at one time.

The golden-robed man who made Li Fei feel frightened frowned slightly, glanced at the void that had just closed, and said lightly: "Strange! That kid just now was only in the late stage of the Realm Formation, and it stands to reason that he should not be able to tear apart the Void, as for the ancient formation underground, it is not something he can move, could it be that there is still a hidden old monster in the Heavenly Formation Stage below?"

"Qiqi Demon Lord, not long ago, a side hall of the temple group was invaded by a human boy, it should only be a monk in the Transformation Domain, but he stole a Thousand Realms Pearl, and none of the eight masters of the late stage of the Demon Saint intercepted him, and finally escaped! An old monster in a silver robe said respectfully.

The so-called Demon Lord is a super master who is one level higher than the Demon Saint, and belongs to the same level as the Heavenly Maturity Stage powerhouse of the human monks, and the strength is so strong that the legend has almost reached the level of a hundred taboos, and he can completely cross the starry sky and be invincible!

Among the demon clans, the demon lord is a real monarch, and there are countless demon clans under his jurisdiction, with a radius of more than 10 million miles, all of which are his territory, which can be said to be extremely powerful! Of course, the strength of the demon lord is absolutely undoubted, with unpredictable magical powers!

Basically similar to human monks, the Tiancheng period is also a very important bottleneck, and it is also the watershed that divides high-level monks and middle-level monks.

After the monk reaches the infant stage, the theory is that he has an immortal body, but when he reaches the heavenly stage, that is the real invincible, because the peerless powerhouses of the heavenly stage have their own independent world, and if they encounter an invincible enemy, they can hide in their own world at any time, so that people can find it anywhere.

Of course, for peerless powerhouses of the same level, the strength is also very different, if one side is much stronger than the other, there are naturally powerful means to find out the opponent and kill it, it is a duel of another level.

After listening to the report of his subordinates, the golden-robed demon lord said noncommittally: "Then let this kid live for a while longer, let's go down first and see if there are any clues near the battle array." ”

With just one flash, dozens of people disappeared on the stone peak, and instantly appeared in the empty underground space, since the entire Battle Demon Array was emptied by Xiang Cheng and the others, naturally there was nothing.

After glancing around, the golden-robed demon lord snorted angrily, and with a stroke of his hand in the void, a giant eye the size of a basketball appeared, and with a burst of demonic energy rolling, every move of Li Fei and the others was clearly displayed in it like a movie played back!

Watching Li Fei and the others digging up the immortal crystal, the golden-robed demon lord looked at it for a moment, then became impatient, and with a flick of his giant eye, he entered the quick release mode, until he saw Li Fei release the green enchantment and frantically extract the power of the battle demon array, then his eyes widened suddenly, and he said incredulously: "What kind of treasure is this green silk? It can ignore the strong prohibition and directly absorb the power of the immortal crystal!"

The silver-robed Demon Saint smiled bitterly: "According to a guy named the Wasteland Demon Saint, that green silk is not trivial, and it has the great power to absorb everything, as for what it is, he doesn't know. It's a pity that this guy from the Wasteland Demon Saint is dead, otherwise you can call him over and ask him about it. ”

The golden-robed demon lord stared at Li Fei's green silk, looked at the time of the incense, and suddenly shrugged up, and muttered, "I probably guessed what that green silk is......! You continue to track down the other two old monsters, and let me know as soon as you have any news! I'm going to hunt down that kid myself!"

Before the words fell, the golden-robed demon lord had disappeared without a trace, and a group of demon saints were dumbfounded, but they knew that even if the Thousand Worlds Bead was stolen, the golden-robed demon lord was also unhurried, how could he act so quickly now, and everyone naturally guessed that the green silk was definitely very against the sky!

However, no matter how rebellious the green silk is, these demon saints know that it is the treasure of the demon lord, and it is impossible for them to touch it, and the anger of the demon lord is not something they can bear.

Besides, Li Fei, after crossing more than 10,000 miles, he got out of the spatial crack in embarrassment, judged the direction, tore through the space again, and entered it. After doing this several times, Li Fei, who was already exhausted, finally showed a smile of relief, and did not stop for a moment, submerging into an inconspicuous mountain.

It turned out that when Li Fei came to look for Xiang Cheng and the others, he had already left a way to retreat, and he knew that this Demon Domain battlefield was very dangerous, so he did not hesitate to spend time and set up an interstellar teleportation array hundreds of thousands of miles away from the exit array, just in case of emergency! Now this array really came in handy, buying valuable time for Li Fei.

Otherwise, with Li Fei's ability to tear apart the space of this Demon Domain battlefield just now, not to mention that it is impossible for him to repeat it dozens of times all the time, even if he can keep persevering, the time it will take will definitely be much longer, and by then, the enemy will have already caught up.

Although Li Fei didn't know that the enemy could find out his secret, and he was exhausted, he didn't dare to delay for a moment, activated the teleportation array at the fastest speed, and quickly teleported away. After he left, this interstellar teleportation array was immediately blown to pieces!

As a result, the sound of the explosion was still echoing in the space, and the golden-robed Demon Lord came out of the void, looked at the interstellar teleportation array that had been blown to pieces, and roared angrily: "Damn little reptile, even if you escape this time, this Demon Lord will capture you one day......!
