At this time, Leng Xiaoxiao remembered the skeletons of the tall Liberation Demon Beasts when she entered the door, they seemed to be placed in the shape of a formation, and there seemed to be some connection between the two.

"Isn't this formation the key to opening this teleportation array?" Shangguan Lu asked.

"It's possible. Leng Xiaoxiao also thinks so.

It's just that how to use this formation to be able to open this formation?

Leng Xiaoxiao closed her eyes and thought about the connection between the two and this sacrificial platform in her mind.

Suddenly, a flash of inspiration flashed in her mind, and she immediately opened her eyes, yes! This time, maybe she could use this formation to open this teleportation array.

These bones have long been out of spiritual power, and they can't be used to set up formations at all, and the only thing Leng Xiaoxiao can think of is the formation stone.

The formation stone can also be arranged, although the formation stone is not as effective as these spirit beast arrays, but it is also a good way to arrange the formation.

Leng Xiaoxiao hid the huge formation stone mine directly into their jade pendant space, and there were countless puppets helping her work and mining. She can now have as many formation stones as she wants.

The cloth is such a small array, and she can spread it out at will with one hand.

Thinking of this, Leng Xiaoxiao immediately took action and threw the formation stone around the sacrificial platform, and she had already set up a formation in just the blink of an eye.

"Lady, can you do this?" Shangguan Lu asked.

Is it okay to use one formation to activate another?

"Okay, I won't know until I try. If this doesn't work, then we can think of other ways to do it, don't worry. Leng Xiaoxiao said.

After all, people come up with it, and since someone has a problem for them to solve, it doesn't hurt for them to use their brains. It's already here anyway, and they can't get out of here without finding out, can they?

"The lady is reasonable, then do what you want!" Shangguan Lu said.

Leng Xiaoxiao casually took out a formation stone and threw it in one direction, but in an instant, the formation she had laid out had already been activated.

The blue light of the formation flashed, and the light shone throughout the skeleton cave, and these blue lights did not shoot directly into the altar, but shone in all directions of the entire skeleton cave.

Leng Xiaoxiao pulled Shangguan Lu to her side, only to see a blue light flash from the position that Shangguan Lu had occupied before, and the blue light directly hit the wall of the skeleton cave, directly making a big hole in that place.

"It's dangerous!"

The two of them exhaled, and if they were hit by this light, they would be injured even if they didn't die.

"Be careful, this place is not very safe. Leng Xiaoxiao said.

The formation she had laid out was something she had never done before, and she didn't know what the effect was. Just like just now, if she didn't quickly pull Shangguan Lu, he might have an accident.

Therefore, even if it is a self-arranged formation, there are some uncertain factors.

"Hmm!" Shangguan Lu said.

I saw that the formation lock shot out ten rays of light, five of which hit the top of the cave, and five of which shot above the surrounding walls.

Ten points of light fall on the wall and then begin to reflect and refract again. Ten rays of light soon filled the entire skull cave with light, and the picture was very mysterious.
