Mu Xiyun kept releasing the thunder spiritual power, and the dark spiritual veins in his body were also very stubbornly resisting the thunder spiritual power, as if to warn who was the real overlord.

This phenomenon lasted for more than an hour, and within this hour, Mu Xiyun converged the dark spiritual power as much as possible, and released the thunder spiritual power alone, and finally, the dark spiritual vein seemed to recognize the status of the thunder spiritual vein, and the strength of resistance gradually weakened.

"Although the twin spirit veins are rare, I have seen a few in my previous life. It's unheard of for a realm battle like me!" Bursts of thunder light appeared in Mu Xiyun's hand, his eyes were shocked, and he thought in his heart.

For a long time, Mu Xiyun shook his head slowly, still with a puzzled expression, and then withdrew his spiritual power and stopped thinking.

Suddenly, Mu Xiyun's eyes lit up, as if he had thought of something.

I saw that he took out a black box from the space ring, and there was still a faint ghost light on it, which was the black box that kept the spirit core.

Mu Xiyun opened the black box and took out the ring from it, and it took a long time to fumble.

After getting this mysterious ring on the day he treated Mu Tian's injuries, Mu Xiyun tried various methods to break the seal, without exception, all of them ended in failure.

Because the fourth-order spirit beast and the Earth Spirit Realm martial artist both had the same level of power, Mu Xiyun wanted to use the spirit jade to release the yin and yang qi in it instead of the earth evil qi in the earth spirit mirror, thinking that there would be an unexpected effect, but in fact, the result of using the third-order spirit core was the same, it was just a flash of light, and it would be extinguished after a while.

Mu Tian clearly mentioned that the fourth-order spirit core of the dark attribute must be placed together with the ring to unlock the seal, so Mu Xiyun selected various dark attribute elixirs and refined them into liquid medicine, in order to try to unseal the ring, and then even used poison, and even deliberately refined the medicinal liquid to the yin to evil for soaking, but the result was still nothing.

Just now, Mu Xiyun had a flash of inspiration, and thought of his dark spiritual vein, if you want to talk about the spiritual power of the dark attribute, this is undoubtedly the most suitable, but because Mu Xiyun's previous cultivation only opened the Eight Realms, he never considered this method at all, and just after breaking through to the spiritual realm, after a battle between the dark spiritual vein and the thunder spiritual vein, Mu Xiyun was full of confidence in the dark spiritual vein on his body, and felt that it was not impossible to try it.

I saw Mu Xiyun sitting cross-legged on the bed, holding the ring in his left hand and his right hand flat, and then, a purple and black light appeared in the palm of his right hand, and it became more and more intense.

Then, the purple-black spiritual power slowly floated towards the ring under the guidance of Mu Xiyun, and the spiritual core on the side seemed to be induced, and it also overflowed with a slight breath and merged into the ring along with the purple-black spiritual power.

A moment later, the ring flashed again, but it didn't disappear as before.

Seeing this, Mu Xiyun's eyes lit up, his face was happy, and then, his spiritual power was released, and he swept towards this mysterious ring like a space exploration ring.

At the moment when the spiritual power touched the ring, Mu Xiyun's pupils contracted suddenly, and his whole body froze, feeling that his soul was being torn by a wild beast, and the pain was cracking, but he couldn't make a sound, and then, Mu Xiyun's eyes were hollow, his whole body was paralyzed, and he fell asleep on the bed.

In the mysterious space...

"Where is this?" Mu Xiyun's consciousness slowly woke up, thinking in his heart.

Looking at the darkness around him, Mu Xiyun looked puzzled, wasn't he trying to unlock the seal of the ring? Why did he suddenly come here.

"Huh?" Mu Xiyun seemed to feel that something was wrong, and then looked at his body, his eyes suddenly widened, and his face was confused.

"Damn! Why don't I have clothes?" Looking at his slick body, Mu Xiyun subconsciously blocked the important parts with his hand, but soon, as if he found that there was no one around, he breathed a sigh of relief, and then let go of his hand.

Mu Xiyun quickly recalled every detail that had happened before, and after releasing his spiritual power and touching the ring, he only felt a pain in his mind, and then appeared here inexplicably.

Thinking of this, Mu Xiyun's eyes widened again, with a look of disbelief, and muttered, "Could it be that I have entered the ring?"

As we all know, the space ring can only store items, and it can only store dead things, although it can be searched with spiritual power, but it can't let the soul enter it, but now, in addition to the possibility of entering the ring, Mu Xiyun can't think of a more suitable reason at all.

Seeing that the surroundings were pitch black, Mu Xiyun subconsciously released his spiritual power, wanting to explore the surrounding terrain, but suddenly, at the moment when his spiritual power was released, the scene in his vision suddenly lit up, and he found that he was actually in a cave.

Mu Xiyun's shocked face was even worse, if he had guessed that he was in the spatial ring before, then the scene he felt now was as if he was in reality.

As if seeing the entrance of the cave, Mu Xiyun subconsciously walked around, but only took a few steps, and suddenly, he was blocked by a transparent light curtain.

Mu Xiyun stumbled and almost fell to the ground, and most of his spiritual power instantly dispersed under this touch, and his vision suddenly became dim.

Then, Mu Xiyun released his spiritual power again, but he didn't touch the light curtain again, but turned around and walked towards the depths.

Came to the end of the cave, looked at the surrounding rocks, listened to the sound of dripping water, and the echo of footsteps that rang in his ears from time to time, he couldn't help but feel a strange feeling in his heart, if it weren't for Mu Xiyun's memories of his previous life, he really wouldn't dare to come in like this.

As far as the eye could see, there was a large pink bed in the cave, and on the bed lay a young girl who looked only fourteen years old.

Mu Xiyun's eyes widened, and he looked at the body in front of him in a daze, and he couldn't take his eyes off it for a while.

I saw her hands clasped in front of her, her beautiful eyes were closed, her delicate little face was quiet, her cherry-like mouth was delicate, her eyebrows were as thin as willows, her waist was like a bundle, her slender legs were as tender and silky as jade, her two jade feet were as delicate as ice lotus, and there were delicate toes like jade, which were crystal clear, which made people can't help but feel angry and bloody.

After a while, Mu Xiyun came back to his senses from his stunned and turned his head with difficulty, as if he was trying his best not to look at the body anymore, for fear that if he continued to look at it, he would not be able to stop the Yu fire that was about to erupt in his body.

Mu Xiyun took a deep breath, calmed his body slightly, and then took a few steps closer and said tentatively: "Little sister!"

When the words fell, the girl did not move at all, and Mu Xiyun saw the unconcealed ketone body again, the two soft balls that were slightly raised on the snow-white skin looked like they had a considerable scale, and above the softness were two bright red jade beads, which were particularly eye-catching, and people couldn't help but feel a sense of suffocation.

Mu Xiyun hurriedly turned around, gathered his mind, and controlled himself with great concentration to stop looking at this body, he believed that if he continued to look at it, it was very likely that he would "confess" here.

Compared to entering this space, Mu Xiyun was more puzzled, how could there be a girl here, and she was naked, uh... That's not the point, the point is, is she also sucked in?

Mu Xiyun was thinking about it, and then his face changed, and he found that his spiritual power seemed to be about to bottom out, and then he suddenly withdrew his spiritual power, and suddenly, the surroundings became dark again, and his consciousness gradually blurred.
