Looking at the prohibition that would only flash when a drop of evil dragon essence blood was waved, Ning Xin frowned tightly, and constantly sighed in her heart that the dragon clan's prohibition was extraordinary, if it weren't for the evil dragon essence blood to make it appear, she wouldn't have been able to find it through countless times.

"How can this dragon clan's ban be broken?" Looking at the empty front, Ning Xin had a headache, knowing that the ban was in front of her, but she had no way at all.

She had tried to forcibly break the prohibition before, but as soon as the spiritual power was swung out, it was like hitting the air, directly penetrating, and the prohibition seemed to not exist at all!

"The dragon clan pays special attention to the bloodline, it is possible that the essence blood of the evil dragon in your hand is not the same as the dragon clan that set up this ban, so you can't open the ban!"

"Then what should I do, could it be that I still have to go to the Four Great Dragon Palaces to collect dragon blood and see if there is anything that can open the ban?"

"Now the dragon bloodline of the Flowing Wasteland Realm is even more impure, even if you collect it, it is useless!"

"Is it possible to do this?" Ning Xin was a little unwilling, and suddenly a flash of inspiration flashed in her eyes, and she said in unison with Xiaobai.

"By the way, and Xiaolong!"

"Have you forgotten the little dragon?"

"Didn't you keep saying that Xiaolong's bloodline is strong, maybe its essence blood can open this prohibition!" Ning Xin looked happy, quickly dodged into the space, and went straight to the Lingquan River.

"Master!" Seeing Ning Xin appear, Xiao Hei was first overjoyed, and then as if he had thought of something, he hurriedly threw aside the piece of dragon meat in front of him, which was several times larger than it, and looked at Ning Xin attentively.

"When did you wake up?" Ning Xin walked towards Xiao Hei, probed its body, and found that everything was normal before retracting her aura.

"I've been awake for a long time, and when I see that my master is not there, and the little dragon is still asleep, I want to eat dragon meat when I'm bored. ”

"Those dragon meat are all yours, I don't want to limit how much you eat, I'm worried that if you eat too much, you won't be able to digest the spiritual power in it, and your body will be damaged, so you must pay attention to proportions when you eat it in the future. ”

"Master, don't worry, I will!" Except for the first time, because the dragon meat was too delicious, it didn't catch it at once, and when it ate it later, it was very restrained, the pain of the body being torn apart and about to explode, it didn't want to experience it a second time!

"It's good that you know, I'll go see Xiaolong!"

Looking at the little dragon that was still sleeping and molting little by little, Ning Xin hesitated, "I take the essence blood of the little dragon now, will it hurt it?"

"As long as you don't bleed it, it'll be fine!" Thinking that the master used the essence blood of the little dragon like wasting the essence blood of the evil dragon before, Xiao Bai shivered directly.

"How could I do that!" Ning Xin used her spiritual power to carefully cut a cut on Xiaolong's chest, and in an instant, a stream of scarlet blood flowed out.

After collecting a vial of dragon blood, Ning Xin covered her hand over the little dragon's wound, and a soft blue light immediately flashed, and in less than a few breaths, the wound disappeared at a speed visible to the naked eye.

Seeing that Ning Xin was about to leave the space, Xiao Hei hurriedly said, "Master, I'm going out too!" Xiao Long was sleeping, and it was very boring to be a bird in the space.

"Xiao Hei, I'm at the bottom of the sea now, I don't know what the situation is at the bottom of the sea, when I'm sure it's safe, I'll take you out, you cultivate in the space first!"

"Well, master, be careful!"

After leaving the space, Ning Xin first waved out a drop of the evil dragon's essence blood, and after determining where the prohibition was, she was a little nervous and waved a drop of the little dragon's essence blood towards the prohibition! "Be useful!"

"Why didn't you react, the bloodline of the little dragon will not be weaker than that of the evil dragon, right?"

"Uh, probably not!" Xiaobai was also a little surprised.

After that, Ning Xin waved out a few drops of Xiaolong essence blood, looking at the prohibition that still had no reaction, she was a little disappointed in her heart, and finally thought about it, and simply spilled all the remaining essence blood in the jade bottle.

"I don't think this ban can be broken!" The place where the ban was located was still pitch black, and there was not even a flash of aura.

Ning Xin was a little frustrated in her heart, but she was quickly relieved, she understood that there were too many strange things in the world, and it was impossible for her to break them every time she encountered them, "I'll remember this location first, and then try it after I go up to collect other dragon blood!"

However, as soon as Ning Xin raised her head, she was stunned, in the blue sky where the blue light flickered, four green dragons formed by a trace of green mist were gradually appearing.

As soon as the green dragons converged, they began to swim and hover above Ning Xin's head, and wherever they went, a golden light immediately flashed, and almost instantly, the originally dark seabed became golden and dazzling!

In the wandering of the green dragon, a magnificent and majestic palace slowly appeared in Ning Xin's sight.

After the palace was all revealed, the four green dragons turned into a spiritual light and attacked directly in front of Ning Xin's position, and in an instant, four dragon pillars were formed, like four solemn guards, and a road completely paved with ten thousand years of cold crystals appeared at Ning Xin's feet.

"I'll just say that there must be a powerful cave near the dragon vein!" Xiao Bai said arrogantly.

Looking at the crystal road that could shake her eyes blindly, Ning Xin was a little stunned, "Can I go in?"

"It should be!"

Ning Xin controlled the blue bubbles to fly over the four dragon pillars, came to the gate of the palace, and felt that the sea water was blocked, so she removed the bubbles!

"Don't go in!" Ning Xin was just about to push open the palace gate when she heard Xiao Bai shouting eagerly.

"What's wrong?"

"There is immortal qi in it, although you have an immortal body but no immortal bones, you can't absorb immortal qi, and you will explode and die if you go together!"

"How can there be a fairy spirit here?"

"This Flowing Desolate Realm is much higher than other interfaces, in the beginning, it should be the interface where immortals and mortals coexist, this palace should have been buried at the bottom of the sea and never been discovered, so the immortal qi inside can be preserved forever!"

"I can't absorb immortal qi, but you can, in this way, I enter the space, you enter the palace!" Saying that, Ning Xin quickly arranged an isolation array at the gate of the palace, and then sacrificed Xiao Ding out.

"Xiaobai, can you open the palace yourself?"

"Of course!"

"Okay, I'm in the space, after you absorb the immortal qi inside, I'll come out again!" Ning Xin added to the space in a flash.

After Ning Xin left, Xiao Ding couldn't wait to rush towards the palace gate, "Squeak!" The palace gate slowly opened, and a thick fairy aura greeted him, Xiao Ding trembled excitedly, and made a comfortable sound.

"Huh!" Xiao Ding rushed to the center of the palace like a bolt of lightning, and began to frantically absorb the immortal qi in the air.

"It's been a few days, and I don't know if Xiaobai has finished absorbing the immortal qi?" In the space, Ning Xin sorted out the elixir field, probed Xiaolong's body again, and refined a few furnaces of elixir before hesitating to go out!

"Let's go out and have a look first!" Raising the aura cover, Ning Xin quickly dodged out of the space.

Seeing that the aura cover was unresponsive, Ning Xin knew that there was no immortal qi in the air, and after removing the aura cover, she walked towards Xiao Ding, who was motionless in the palace.

As soon as Ning Xin approached, Xiao Ding automatically returned to her dantian.

Before she could find out about Xiaobai's situation, Ning Xin was sucked away by the pearlescent treasures in the palace!
