But it's a pity that the Shadow Void Fire is restrained by the ban.

Meng Shuyi was not proficient in the formation, so she didn't dare to break the ban rashly, so she had to put away a half-immortal arrow and leave with regret.

Li Xuedong came to the front of the natural formation, and soon he found the location of the formation gate, and without destroying the whole of this natural shielding formation, he directly dodged and moved in.

After entering the inside of the formation, Li Xuedong really saw a circular stone chamber appear in front of him, but he didn't see the so-called Shadow Void Fire.

Li Xuedong carefully inspected all around the stone room, and found no other traces of people coming in, except for a few footprints that were very old.

The footprints left on the ground obviously belonged to a woman, and they should have been left by Meng Shuyi back then.

Since no one else came in after Meng Shuyi, and the Shadow Void Fire was restrained by the ban, it should not be taken away.

Thinking of this, Li Xuedong immediately searched every area of the stone chamber with his divine sense.

When his consciousness touched the wall on the west side of the stone chamber, he suddenly felt a burning sensation.

This burning sensation shocked Li Xuedong's heart, and then he sacrificed the Chixiao Flying Sword to split the stone wall.

A red flame suddenly appeared in front of him, and there were shadows floating around the flames, and there was a black spot the size of a peanut in the middle of the flame center, which was the characteristic of the shadow void fire.

The moment he saw the shadow void fire, Li Xuedong felt a palpitation, he really saw a strange fire from heaven and earth.

If other people saw the Shadow Void Fire, they would definitely be eager to use the True Element to ingest it.

But Li Xuedong didn't, because he had already discovered that the Shadow Void Fire was forbidden and imprisoned Ning in the stone wall.

These prohibitions are not simply confinement prohibitions, but also offensive prohibitions.

In other words, if the ban is forcibly broken, it is likely to be attacked by the ban.

Of course, this is just for ordinary people, Li Xuedong can even arrange the most difficult formation such as the teleportation array, and the prohibition is born from the formation, and it is obviously easy to break these prohibitions.

But just as Li Xuedong was about to break the ban, he suddenly discovered that the Imprisoned Shadow Void Fire was not only the prohibition on its body, but also a formation connected to the ban.

This formation was set up extremely hidden, if Li Xuedong hadn't been cautious everywhere, he would never have discovered this hidden formation.

The concealed formation in front of him was not a simple formation, but an extremely advanced phantom killing form.

The array banner of this illusory killing array is those stones scattered all around, and the array eye is the wall that imprisons the shadow void fire, and the one who can arrange such a high-end formation is definitely a formation master.

Although Li Xuedong can only arrange the third-level formation now, he has a set of formation theories of the Medicine King in his mind, and although his formation cultivation has not yet reached the master realm, his theoretical knowledge has reached the formation master realm, so he quickly recognized the existence of the phantom killing array.

"What a powerful illusion killing array!"

Li Xuedong did not rush to crack the phantom killing array in front of him, but continued to observe the surroundings with his divine sense, beware of others who did not notice the existence of the crisis.

Fortunately, Meng Shuyi didn't forcibly break the ban and collect the Shadow Void Fire, otherwise even if he succeeded in breaking the ban, he would be slashed to pieces by the Phantom Killing Array in the next moment.

After Li Xuedong checked the entire stone room again, his face had turned pale.

A startling discovery was made by him, and he discovered that there was a corner of the stone chamber that was actually embedded in the natural formation outside.

When he first entered the natural formation, he thought that someone had accidentally discovered this natural formation, and found the Shadow Void Fire inside, but for some reason there was no way to collect him, so he used the prohibition to temporarily imprison the Shadow Void Fire, and then built a stone room outside to protect it.

But now he realized that his guess had been wrong.

If it is true that there is a natural formation first, and then someone builds a stone chamber, it is impossible for the stone chamber to be embedded in the natural formation anyway.

Once this statement is not true, then the only explanation is that there is a stone chamber first and then a formation.

The circular stone chamber in front of me could not have been formed naturally in any way, and it looked like it had been piled up by people.

After thinking about it all the way from this aspect, a frightened thought emerged, the natural shielding formation outside was actually artificially arranged.

The realm of the formation mage who arranged this formation was extremely profound, and it was not even inferior to the Medicine King who had been in the cultivation realm.

After considering this, Li Xuedong forcibly calmed himself down, and he felt that things were much more complicated than he imagined.

If this Shadow Void Fire was really born here, with the cultivation of that formation master, it would be absolutely impossible for him not to be able to accept it.

Since he had the ability to take away the Shadow Void Fire, he didn't take it away, but instead left it here, put a ban on it, built a stone room, and arranged a pseudo-natural shielding formation of extremely high level outside.

There is probably only one reason why this person wastes so much time and energy to arrange these, and that is that he deliberately imprisoned the Shadow Void Fire here.

Heaven and Earth Alien Fire is different from ordinary True Fire and Dan Fire, they can grow, don't look at the Shadow Void Fire is only the seventeenth Earth Fire in the cultivation realm, but if it grows up, then its power is even much more powerful than the other Earth Fires that were ranked before.

According to the description in the memory of the Medicine King, the growth of the Heaven and Earth Alien Fire is divided into seven levels, and the flame will undergo a color change for each level of growth.

The most basic Heaven and Earth Alien Fire is dark red, and then its color changes accordingly as it grows in different realms, and the colors from low to high are red, orange, yellow, green, cyan, blue, and purple.

Even so, it is very difficult for the growth of the Heaven and Earth Alien Flame, not to mention that the Purple Flame of the seventh layer is rarely seen, and even the Flame that advances to the third layer of the Yellow Flame is rare.

The Medicine King once obtained a Heavenly Fire named Qianyang Yan, but this Heavenly Fire was nothing more than an orange flame.

As for whether the Medicine King's flame had grown further after he ascended to the Immortal Realm, Li Xuedong didn't know.

The outer flame of the Shadow Void Flame in front of him was crimson, but the inner flame had turned orange, which meant that it would soon be upgraded to the second layer of orange flame.

Li Xuedong didn't expect that he not only got a heaven and earth fire, but also a fire that had grown to the second layer of orange flames, which can be said to be so good that his luck exploded.

Li Xuedong was once again deeply grateful to Meng Shuyi in her heart, she actually told him the secret of such a precious fire, you must know that the Heaven and Earth Alien Fire that advanced to the second layer of orange flame is a priceless treasure, and Meng Shuyi can use this secret to exchange for any resources she needs.

After realizing that the Shadow Void Fire was already an orange flame, Li Xuedong couldn't hold it anymore, and immediately began to crack the illusion killing array.
