After leaving the space ring, Jian Chen and Shangguan Mu'er left the Dragon Tomb and rushed straight to the Xingyue Cave.

Xingyue Cave is a very deep hole on Dragon Island, the origin of this cave is that the Yin Yang Holy Stone flew from the sky and smashed on Dragon Island, and it was also because of the Yin Yang Holy Stone that Dragon Island had a mutation, and a large number of walking corpses appeared.

Jian Chen and Shangguan Mu'er came to the land of Xingyue Cave, here, there are still a lot of Heavenly Star Powder, which is one of the materials for refining the Immortal Grade Purple and Blue Double Sword, such a material is a top category in the Tianyuan Continent, but if it is taken to the Holy Realm, it is almost worthless.

At the bottom of the Xingyue Cave, there is the formation that Mo Tianyun arranged back then, and this formation can directly lead to the location of the Yin Yang Holy Stone. But fortunately, the Ziqing Sword Spirit knew this formation, and then, Jian Chen and Shangguan Mu'er stepped into the formation through the method told by the Ziqing Sword Spirit, and stepped into the formation according to a specific law and direction. After taking the eighth step, the sight of the two of them suddenly changed, only to see that they had left the Xingyue Cave and appeared in a dark and cold cosmic void, as far as the eye could see, the sky was full of twinkling stars, and the planet where the Tianyuan Continent was located had long been hidden in the heavens and stars, and they couldn't find anywhere.

With that step, Jian Chen and Shangguan Mu'er had already crossed an unimaginable distance and appeared in the void that they didn't know how far away they were from the Tian Yuan Continent.

Although such a scene Jian Chen and Shangguan Mu'er had already experienced, but this experience, the shock in their hearts was much stronger than the first time, when they experienced such a scene for the first time, they only had the strength of the Holy King, both their cognition and vision were extremely limited, at that time they thought that as long as they surpassed the Holy Emperor, they would be able to arrange a formation that spanned endless distances, and even with their own strength, they could travel in the void and shuttle at will. But it wasn't until they became strong in the Source Realm today that they understood more deeply how rebellious the formation Mo Tianyun had laid out back then.

With their strength, they can indeed travel freely in the outer void, but the distance is extremely limited, if they go to the moon star that is not too far from the Tian Yuan Continent, it may be easy, but if they want to cross such a long distance at this moment, not to mention how many years they will fly at full speed, just this vast sea of stars is enough to make them lose their way, even at this time, standing in this void, without the help of the formation under their feet, they will not be able to find their way home at all.

"Follow my footsteps, don't make a mistake, once you step outside the spatial node, you will be lost in the void. Jian Chen tightly took Shangguan Mu'er's hand, and said with a stern face, at this moment, even he didn't dare to be careless, and completely obeyed the Ziqing Sword Spirit.

Shangguan Mu'er nodded slightly, she also understood this truth very well, and stood beside Jian Chen obediently, not daring to step indiscriminately.

With the help of the Ziqing Sword Spirit, Jian Chen and Shangguan Mu'er stepped step by step in the void, each step happened to step on a spatial node, each step out, the vast sea of stars around them were changing, this was too far away to lead the way, but this scene did not last long, when they took the thirtieth step, the surrounding scenery suddenly changed, and under a closer look, the two of them appeared in a space passage with a diameter of ten meters, and there was chaos around the passage, and they couldn't see anything clearly.

One qiē was the same as when they first came, and then, Jian Chen and Shangguan Mu'er stepped into the spatial passage, and came to the place where the Yin Yang Sacred Stone was located, which was a gray space, without any life, and the whole world was as silent as death.

Originally, this was a void space, when Mo Tianyun moved the Yin Yang Holy Stone here, and the Yin and Yang Qi that leaked from the Yin and Yang Holy Stone from time to time evolved the rules of heaven and earth, created all things in heaven and earth, and gradually formed such a lifeless world.

Successfully stepping into the world of the Yin-Yang Holy Stone, Jian Chen finally breathed a sigh of relief, and then came to the place where the Yin-Yang Holy Stone was located with Shangguan Mu'er.

The place where the Yin-Yang Sacred Stone is placed is a very large cone-shaped deep pit, and the Yin-Yang Holy Stone is suspended at the very bottom of this cone-shaped deep pit.

When Jian Chen saw the Yin Yang Sacred Stone again, although the Yin Yang Holy Stone emitted a strong black and white light, completely obscuring its body, Jian Chen could still clearly see the Yin Yang Holy Stone hidden in the black and white light.

The Yin Yang Holy Stone is not big, it looks like it is only the size of a fist, one black, one white is stored separately, but this small Yin Yang Holy Stone, the terrifying energy contained in it, makes Jian Chen's heart tremble, if this energy explodes, I am afraid that the entire universe will be destroyed.

Moreover, among these two Yin Yang Sacred Stones, Jian Chen clearly saw that there was a little bit of red red light flickering, as if it was slowly beating like life.

Jian Chen didn't know what this red light was, but the moment he saw this red light, the hairs in his whole body exploded, and a cool breath came from his backbone uncontrollably, and his heart beat violently at this moment.

Not only him, but even Shangguan Mu'er's complexion changed greatly at this moment, staring at the Yin Yang Holy Stone with a pair of beautiful eyes, it was obvious that this red glow brought her the same feeling as Jian Chen.

"Could this be the evil power hidden in the Yin-Yang Sacred Stone?" Jian Chen's eyes revealed a monstrous glow, and he also stared at the red light in the Yin-Yang Holy Stone, and his heart was greatly shaken.

Just one glance brought him such a strong feeling, and the terrifying Cheng Dù of this evil power far exceeded Jian Chen's imagination.

"The power of good and evil, once this force is out of trouble, it will bring about a catastrophe that destroys the nature, it seems that this is the key to the catastrophe of heaven and earth, manpower is irresistible, and the silk of the ancient gods is the thing that breaks the catastrophe. The illusory body of the Ziqing Sword Spirit also manifested, staring at the Yin Yang Sacred Stone with a solemn face.

Suddenly, the faces of the two of them changed in unison, and they exclaimed: "It's not good, this evil force is actually absorbing the yin and yang qi of the Yin and Yang Holy Stone, this will only make it stronger, we must find a way to stop it, otherwise, when it is strong enough to reach a certain level, I am afraid that the ancient god silk will not be able to restrain it." ”

"But this evil force is hiding in the Yin Yang Holy Stone, and this Yin Yang Holy Stone can't be touched, in case Yin and Yang are out of balance, I'm afraid we don't need this evil power to grow, and we have already experienced the catastrophe from the Yin Yang Holy Stone. Jian Chen said with a frown, his face was very solemn.

"Now you have to snatch the yin and yang qi with it, master, you can't delay, you must immediately start absorbing the yin and yang qi, absorb as much yin and yang as possible, and you must not let this evil force continue to grow. Qing Suo said in a deep voice.
