If for Ning Xin and the others, the land of the Demon Palace and the Demon Vein is hell, then for the three of the Night Demon Lord, this is heaven, and as soon as they enter the land of the Demon Vein, the three of them all let out a comfortable breathing sound.

"Hehe, we have finally entered the land of this demon vein! this time it is really thanks to those Dao cultivators, without them, the three of us would not be able to deal with the demon dragon. The black-headed old ghost looked around with glowing eyes, the soul crystal should be somewhere here.

"Hmph, it's really cheap for them, we have been fighting with the demon dragon for more than a month, and after several lives and deaths, the body of the demon dragon was taken by those Taoist cultivators, I am not willing to think about it. The old monster said dissatisfied.

"Be content, if it weren't for those Taoist cultivators, do you think we would be able to enter here? Compared to the Demon Dragon, this place is our main purpose, isn't it?"

"Hey, this Yue Heavenly Realm is just such a demon dragon, we encountered it, but we didn't catch it at all. The old monster said a little willingly.

"Demon Lord, it's okay, I'll leave first. The black-headed old ghost glanced at the Night Demon Lord who had been silent since entering the land of the Demon Vein, and he was a little eager to find the Soul Crystal now, but he didn't have time to accompany them to be stunned or complain.

"Yes. The Night Demon Lord replied faintly.

The black-headed old ghost and the bloody old monster glanced at each other, didn't say anything, and quickly flew in different directions in the land of the demon vein. After the two left, the Night Demon Lord immediately flew to the black stone platform.

After carefully probing around the Black Stone Terrace, he didn't find anything abnormal, the Night Demon Lord frowned, when he first entered here, he seemed to feel the fluctuation of the aura, how could Dao Xiu enter here?

I don't know what I thought, the Night Demon Lord's expression suddenly changed, and he immediately took out a white jade bottle, sacrificed the last drop of blood in the bottle, and sprinkled it into the air.

"How can this be?" Looking at the empty three light curtains, the Night Demon Lord was a little dumbfounded, "Could it be that there was really a Dao cultivator who entered here before and took away the Heavenly Demon Ball?" Thinking of this possibility, the Night Demon Lord's expression became very hideous.

"Dare to thief, dare to steal the treasure of my demon clan, this monarch will let you die without a place to live. The Night Demon Lord roared with excitement, his chest rising and falling with rage.

Ning Xin and the six of them were still teleported to the Demon Source Palace, carefully probed the situation outside, and found that the Departure Palace was very quiet at this time, and the demon dragon hovering above the Departure Palace was no longer there.

Outside the Demon Source Palace, the compound killing array arranged by Ning Xin had been forcibly destroyed, and the two demon generals trapped in the formation fell to the ground lifelessly.

"They should have been killed by the Demon Cultivator, and the strength of the Demon Cultivator should be very strong. Murong Xuan looked at the two demon generals on the ground and said.

"Let's get out of here. Ning Xin suddenly felt a fluster, and hurriedly said to several people.

The ones who could kill these two demon generals so easily should be the three of the Night Demon Lords, they may have entered the land of the demon veins now, if they find that the contents are missing, they will definitely come to hunt them down.

Looking at Ning Xin, who looked anxious, several other people immediately walked cautiously towards the gate of the Departure Palace, there were corpses everywhere along the way, there were demon soldiers and demon generals, and there were also demon cultivators, and when they walked to the main hall, they also found the corpses of many Yuanying monks.

"It seems that there was a fierce fight here!"

"How did these monks get in?"

"It should be that the entrance to the Demon Palace is forbidden to be destroyed!" Ning Xin said as she looked at the corpse of the monk on the ground, but she had some doubts in her heart.

The prohibition at the entrance of the Demon Palace should have been forcibly broken by the Avatar Monks, so that these Yuan Infant Monks could enter the Demon Palace, but how did they pass through the thundering rain and mist area of the Unconscious Canyon?

When Ning Xin and the others came to the back of the departure palace gate, a deep pit hundreds of meters long appeared in the sight of several people, "Has the demon dragon been killed?" Xia Wang looked at the pit and said, sighing a little in his heart.

"No matter how strong the demon dragon is, it can't resist so many monks who want its life. Ning Xin's heart was a little touched.

"Those three demon cultivators shouldn't be able to kill the demon dragon, it seems that the god cultivators on the Tuyue Continent are also involved in hunting the demon dragon. Murong Xuan said with some sighs, the two sides of the Demon Dao can actually join forces for the sake of interests, who doesn't want this ancient demon dragon?

"Don't worry about that, let's go. Han Rou glanced at a few people expressionlessly, and took the lead in front.

After going through so many things, she has long looked down on life and death, except for a few people who can still make her worry, and now many things can't make her heart fluctuate.

After leaving the Departure Palace, Ning Xin and the others ran directly in the direction of the entrance of the Demon Palace, along the way, the Demon Palace was no longer what it was when they first entered, and now it was full of messes, corpses and bloodstains.

At this time, in the center of the Demon Palace, Wen and Daojun of the Tianyue Sect walked out of the Eternal Life Valley with Gu Tianling, Yang Yuwei and several Gu family disciples covered in injuries.

"Yuwei, how do you know that there are no treasures treasured by the demons in this Eternal Life Valley?" Wen He Daojun thought for a while, and still asked Yang Yuwei.

Although some of the things in this demon palace will be recorded in some inherited classics, he doesn't think that this female disciple in front of him who has no family background can know and know so clearly.

"Elder Hui Taishang, the disciple also saw it in the Mu family's library. Regarding Wen He Daojun's questioning, Yang Yuwei was a little nervous.

After thinking about it in his mind, he attributed the matter of knowing the Demon Palace to the Mu family's library, anyway, Mu Ningxin and Mu Ningyi were the first to enter this Demon Palace, everyone knew about it, and others would not suspect anything when she said this.

The reason why she knew about the things in this Demon Palace was actually because of a jade slip in the space, which recorded the distribution of the Demon Palace in detail, and originally she only wanted to bring Gu Tianling and a few people to this Eternal Life Valley.

Unexpectedly, Wen He Daojun suddenly appeared, but fortunately he appeared, otherwise they don't know how many people would have died, the strength of the four demon spirits in the cave is really too strong, looking at Gu Tianyou who was leaning on Gu Tianling with a pale face, Yang Yuwei was a little worried in her heart.

Although they got a lot of things in it this time, they were all magic plants, magic weapons and the like, not only did they not have any particularly precious things, but these things were not of much use to them, and she always felt as if they had been picked and leftover.

"Mu family, it seems that the Mu family is very good to you, and even let you enter the library building. Wen He Daojun glanced thoughtfully at Yang Yuwei and Gu Tianling beside her.

This Eternal Life Valley knew at a glance that someone had already come, not only took away the treasures in the cave stone room, but also killed all the demon generals and demon soldiers guarding here, could it be Mu Ningxin and a few people?

This Yang Yuwei didn't tell the truth, the ban in front of the cave, even if he, the god cultivator, came, he couldn't break it, was it really like she said that she broke it unintentionally?

Wen and Daojun's words made Yang Yuwei a little embarrassed, and at the same time, she also felt sarcastic in her heart, the Mu family was good to her on the surface, but how many people really cared about her?

If it weren't for the fact that every time she went to Mu's house, she would bring Mu Qian the precious elixir of the higher age in the space, would he be kind to her?
