As soon as the Night Demon Lord heard the sound of the dragon's groan, he immediately rushed in the direction where the sound came from, and only the Demon Dragon was guarded by the Demon Palace in the Departure Palace, and the Departure Palace was the purpose of his long journey.

Some of the other cultivators in the Demon Palace with high cultivation levels all rushed in the direction of the sound after hearing the dragon's roar, among which the Blood Elder Monster and the Ghost Ancestor were particularly fast.

"Could it be that there really is a dragon in this demon palace?" Guangping Daojun looked at the demon cultivators, demon generals and demon soldiers who were constantly running in the direction where the dragon's groan came from, and he couldn't hide his shock in his heart.

"Millions of years ago, the cultivation realm was so prosperous, like dragons and phoenixes, which are only recorded in the classics, naturally exist, Qinghua and Xingzhi must have followed, let's go over and take a look!" Kong Daojun also said with some emotion, and then quickly flew forward.

In the Demon Source Palace, Ning Xin and the others looked at the black demon dragon that was constantly hovering above the Departure Palace, and they were all very shocked in their hearts, "We actually saw the legendary true dragon!" Xia Wang looked at the giant dragon flying in the air, and said with a trembling voice.

"No wonder I felt that the three words of the Departure Palace were a little familiar before, Ning Xin, the Demon Dragon is a magical beast that specializes in guarding the Demon Palace Demon Vein and the Demon Venerable, this Departure Palace is the palace where the Demon Venerable lives, and this underground is where the Demon Palace and the Demon Vein are located. When Xiaobai saw the demon dragon, he immediately sent a message to Ning Xin.

"Demon Dragon!" Ning Xin looked at the black dragon in the air with a serious expression, from the previous dragon groan, she felt the huge and powerful power of the demon dragon, and said with some worry, "I'm afraid it will be even more difficult for us to get out of here." ”

"Yes, it is still possible for us to defeat those two demon generals with all our might, but this demon dragon is really not something that you and I can compete with!" Murong Xuan said with an ugly expression.

"There are a lot of demon soldiers and demon generals who are coming towards the Departure Palace, and there are also demon cultivators, those demon cultivators have entered the Demon Palace!" Han Rou said to Ning Xin and the others with a somewhat panicked expression.

Since her cultivation had been abolished once before, after reappearing in cultivation, her divine sense was stronger than that of ordinary people, since she entered the Demon Source Palace, because she was afraid of any danger, her divine sense would scan the surroundings of the Departure Palace from time to time, so she would find it for the first time.

"Han Rou, hurry up and withdraw your divine sense. Ning Xin hurriedly said, "Those demon cultivators didn't find you, did they?"

"Probably not, they are followed by a large group of demon generals and demon soldiers, and it is too late to deal with them, so they won't notice me. What's wrong?"

"A few of us were the first to enter the Demon Palace, and at that time, the Demon Soldiers and Demon Generals in the Demon Palace had not yet awakened, so they naturally thought that we had taken a lot of treasures from the Demon Palace, and those Demon Cultivators would not give up on us. ”

"According to Senior Sister, if they find us, they will not have to kill us as soon as they come up, and then snatch the storage magic weapon in our hands. ”

"Demon cultivation is not like this, if you see something, you will grab it directly. ”

"So what are we going to do now?"

"It's not easy for those demon cultivators to get in, not to mention that there is that demon dragon, let's just say that the demon soldiers and demon generals behind them are not easy to deal with, as long as we don't go out, there will be no danger in a short time. ”

"We can't get out, what should we do if the demonic energy in Senior Sister Shui Lan's body can't be controlled?"

"Shui Lan, if you feel that the demonic qi in your body shows signs of rioting, take a Demon Pill. Ning Xin handed a jade bottle containing five Demon Pills to Mu Shuilan.

"Remember, don't use the aura. Ning Xin looked at Mu Shuilan seriously, this was the last few Demon Pills on her body, if they hadn't gone out by the time Shui Lan finished eating, she didn't know how long Shui Lan would be able to last.

"Okay!" Mu Shuilan nodded at Ning Xin, she also knew in her heart that the demonic qi remaining in her body was emitted by a demon general, and it could not be removed by ordinary people.

After that, several people watched the Departure Palace closely, and the black magic dragon guarded the Departure Palace like a mountain, and it didn't take long for the sound of "bell" and "bang" to continue to come from the direction of the main hall of the Departure Palace.

"Those demon cultivators have fought with the demon soldiers and demon generals here. ”

Suddenly, several powerful pressures came from all directions, causing Ning Xin and the others to sit on the ground at once, and Mu Shuilan, who had no aura to protect her body, fell to the ground with a pale face.

When Ning Xin saw it, she hurriedly crawled to her side and quickly fed her a Demon Pill, and after dozens of breaths, Mu Shuilan's breathing stabilized.

At this time, Ning Xin looked up at the top of the Departure Palace, a middle-aged demon cultivator in a black Xuanguang robe, an old man in a black robe, and a red-robed strange man surrounded the demon dragon, and those three of them all exuded extremely powerful coercion.

"They should be the Night Demon Lord, the Black-headed Old Ghost, and the Blood Old Monster who are famous in the Demon Realm. Seeing those three demon cultivators, Murong Xuan's pupils shrank, "Fortunately, the demon dragon intercepted them, otherwise we would definitely be dead and lifeless when we faced them." ”

The demon dragon watched as the three people on the opposite side dared to trespass on the realm it guarded, and let out an angry roar, and a super strong air flow erupted from the demon dragon's mouth, and soon swept in all directions.

Those demon cultivators and demon generals who were still fighting were all swept away by the air current, and those who were closer were directly torn apart by the air current, and even the three of the Night Demon Lords were able to resist with all their might to withstand the powerful power of the demon dragon.

"Ahem" The demon dragon roared, and it was not only those demon cultivators who were unlucky, but also Ning Xin and a few people, the powerful mana of the demon dragon was not something that these Jindan cultivators could resist.

"Senior Sister Shui Lan, how are you? Senior Sister, come and take a look. Xia Wang hugged Mu Shuilan, who was starting to glow with demonic energy again, and called Ning Xin loudly.

"Take out the Demon Pill and feed her one!"

"Xiao Bai, I want to take advantage of the chaos to escape from the Departure Palace while the Demon Cultivator and the Demon Dragon are restraining each other, do you know that there are other exits to this Departure Palace?" Ning Xin looked at the Demon Cultivator and the Demon Palace who were looking at each other in the sky above the Departure Palace, and anxiously transmitted the voice to Xiao Bai.

"With the Demon Dragon here, don't try to escape from the Departure Palace. And I advise you not to leave this palace at this time, only this Demon Source Hall is the safest for you in this departure palace. ”

"Then what should I do? You also saw that if those three demon cultivators and demon dragons fought, not only Shui Lan couldn't stand it, but we couldn't bear it. ”

"Actually, there is another place where you can avoid the crisis for a while, but I don't know if you can stand it?"

"Somewhere, say quickly. ”

"The center of the Demon Palace and the Demon Vein is under your Demon Source Palace. ”

Xiaobai's words made Ning Xin silent for a while, looked at Mu Shuilan, who had passed out again, gritted her teeth and said, "How do you get in?"

"I don't know about this, you have to find it yourself, anyway, the entrance should be in this hall. ”

As soon as Xiao Bai's words fell, Ning Xin quickly arranged a seven-rank defensive array and an isolation array outside the main hall, and then immediately searched for it in this main hall.

"Ning Xin, what are you looking for?" Murong Xuan and the others looked at Ning Xin suspiciously.

"There must be a reason why those demon generals don't dare to come in, maybe there is some secret in this Demon Source Palace, find out, and we may be able to save it." ”

"Then let's find it together!"

This hall was explored several times, and several people found nothing, at this moment, the demon dragon launched an attack on the three of the Night Demon Lord, only to see the demon dragon leap into the air, and the vigorous body was swept away, and a black gas demonic qi with extremely fast wind speed and strong wind power was like a soaring tornado, and lightning attacked the three demon lords.

Along with the black tornado, the seven-rank defensive array and isolation array that Ning Xin had arranged before were instantly destroyed, and several of them were also hit the wall in the main hall by this strong air wave.

Mu Shuilan and Han Rou directly lay on the ground motionless, and Murong Xuan and the others were not much better, and they couldn't get up after struggling countless times.

Just when the three of the Night Demon Lord made a move, Ning Xin, who fell to the ground, threw out a black flag at the only incense burner in the main hall with all her might, and the moment the flag was inserted into the incense burner, several people in the main hall disappeared in an instant, dodging the three more harsh attacks that followed.
