As a result, the figures of the four people instantly became illusory, and when their bodies moved, they formed an extremely magical formation.

As soon as Duan Li'er saw that formation, he understood a little.

It turned out that she knew that the four Heavenly Demons and the others were made of the four spirits.

Among them, the Heavenly Demon represents the White Tiger, the Wutian represents the Green Dragon, the Blood Ancestor represents the Vermilion Bird, and the Qiao Corpse Ancestor represents the Xuanwu.

And at this moment, the formation they arranged was also a kind of four-spirit formation. It's just that Duan Li'er has never seen this formation. It should be a wonderful formation between them to borrow strength from each other.

As for why she did this, Duan Li'er naturally didn't know. But it can be guessed that they should be trying to activate the power of the so-called four spirits to open the third key of heaven and earth, so that it can guide them to the fourth key of heaven and earth.

White Tiger, Green Dragon, Vermilion Bird, Xuanwu. Originally, it was a legendary divine beast that could defy the sky, and such a being naturally had its own unique power.

And the Heavenly Demon and the others, since they were incarnated from these four spirits, of course, they should have inherited part of this power.

The formation they had set up at the moment might be to induce that kind of power. Then enter it into the Phantom Moon Chain and let the Phantom Moon Chain open.

Of course, this is just Duan Li'er's speculation, but it seems that it is also eight | nine is not far from ten.

The original Demon Lord and the Dragon Lord, the two super powerhouses, had already tried, but there was no way to open this Phantom Moon Chain. Maybe it's because of the immaturity of time, or maybe it's because they haven't found the right way.

At this moment, it seems that the Heavenly Demon and the others are already confident, and they should have thought of some way to successfully open this Phantom Moon Chain.

Because of this, Duan Li'er guessed that they would arrange this formation in order to open the Phantom Moon Chain.

According to the specific position of the four people, the figures are disillusioned, and a complete formation has been formed. Immediately, the Heavenly Demon began to chant words in his mouth, which seemed to be a kind of spell for this formation.

After she read for a while, Duan Li'er saw that there were four streams of energy of different colors, rushing out of the Mahayana cover of the four people, and began to form a magical round light bead among the heavenly demons.

Once that light bead is formed, it begins to emit a wave of magical energy.

Although it was very faint, Duan Li'er on the periphery still sensed it.

Immediately, she saw the Heavenly Demon throw the key of heaven and earth, that is, the phantom moon chain, in his hand, and accurately threw it into the bead of light. A change awaits him.

After the light bead was formed, in fact, the formation of the Heavenly Demon and the others was already dispensable.

But to be on the safe side, they were constantly pumping energy into the light beads.

When the Phantom Moon Chain first entered the light orb, it didn't seem to react, it still looked like an ordinary necklace.

But the Heavenly Demon and the others did not give up, they seemed to be convinced that their methods could be effective, and they were still constantly transmitting a huge amount of energy.

And after the four of them continued to input energy, the color of the light bead gradually changed, from transparent at the beginning, to cyan, after a while, it actually changed to a strange blood-red color, and after the red to the extreme, it finally turned black.

Transparency can be regarded as white, which is a unique color belonging to the Heavenly Demon, and the subsequent cyan is naturally unique to Wutian, and then it turned into the strange red of the Blood Ancestor, and finally became the black of the Qiao Corpse Ancestor.

This color change is to manifest the characteristics of all four people. It seems that it has indeed been set by the Heavenly Demon and the others
