Just when the two of them were thinking, Ye Xiyue's hand pressed on the veins, and her fingers pointed back and forth on the veins.

Obviously it was a line of lines, Ye Xiyue was stunned to move back and forth, only to hear a 'click', the floor cracked, and the three of them made an uproar, and they all fell.

The red light was completely different from the previous black confusion, Ye Xiyue stood up and found that they seemed to be in an underground palace.

"Xiyue, did you unravel the formation just now? How do you do it? Chen Xuan patted his buttocks, not quite convinced, "Just put his finger on the ground, and with a few slight clicks, you untied it?" Are you a genius? ”

Ye Xiyue pulled her lips, "I once walked through that formation. ”

"Where have you seen the formation of the Life and Death Domain?" Xue Wuxian was curious, it was the first time he had seen such a ground formation today.

Ye Xiyue spit out lightly: "My family." ”

Two words, directly scorching Chen Xuan and Xue Wu's inner and outer scorching.

"You've seen such a formation in your house?" Chen Xuan's usual curiosity is not very serious, but today, because of Ye Xiyue's approach, he frequently became curious.

Ye Xiyue nodded, she was indeed no stranger to this formation, the formation she saw today was exactly the same as the formation she had walked in the Ye Mansion Great Library Pavilion.

There are two library pavilions in the Ye Mansion.

Small and large library cabinets.

She read all the books in it, and she wouldn't tell anyone that she had the ability to remember.

And the "Supreme Secret Sutra" was contracted by her in the Great Library Pavilion.

Speaking of this, Ye Xiyue felt quite strange, because the large library in the Ye Mansion was not locked, and before entering, she needed to go through the formation in front of the door.

At that time, because she fused the heart of the phoenix, when she was close to the Great Library Pavilion, under the traction of the heart of the phoenix, she walked through that strange formation step by step.

She remembered that there was an old man sweeping the floor in the library at that time, who suddenly appeared and disappeared suddenly.

Afterwards...... She had never been to the Great Library Pavilion, and now that she looked back, she was a little curious about the old man who was sweeping the floor.

It's a pity that she forgot to ask her grandfather before.

Therefore, when she encountered this formation today, she quickly unraveled it according to the steps she had taken at that time.

Looking at the red patches around her, even the stone walls were red, she couldn't help but wonder if there would be a formation of the Ye Mansion in the realm of life and death.

This had to make her curious.

"Let's go ahead and have a look." The snow leads the way unharmed.

Ye Xiyue and Chen Xuan were very curious about this place, looking left and right.

Walking around a corner, Chen Xuan immediately stopped when he saw everything in front of him.

"That's ......," he thought his eyes glazed and took two more steps forward.

Ye Xiyue stood in place, raised her eyebrows, in the middle of the road, a person's bone shelf, standing upright, and around it, there were actually nine dark iron chains.

Xue Wuxian looked at the white skeleton standing in front of them, and a trace of coldness flashed in his eyes.

"This man is dead, why do you still have to lock up his bones?"

"Because of this man, the sin is great."

Chen Xuan looked at Xue Wuxian, "Do you know it?" ”

"I don't know." Ever since the bones appeared, Snow's unharmed eyes had never left the bones.

"Then why are you so deep?"

Xue Wuxian said lightly: "The bones are chained in the middle of the road, you say, how can we get there?" ”
