The sudden coughing sound made Ling Zheng, who was already feeling a little crazy, even more frightened. He knew very well that the cough was not a hallucination, and he looked at the cave as if he were facing a great enemy, only to see that in the dark and secluded mouth of the cave, there were dark blue air currents gushing out.

Before Ling Zheng could come back to his senses, those dark blue air currents converged into a blue light in the shape of an arrow, which hit Ling Zheng's chest at an incomparably fast speed.

Ling Zheng only felt a chill in his chest, and then, that coolness began to spread rapidly towards his limbs, and before Ling Zheng could come back to his senses, he had already lost control of his body.

Similarly, the rat standing on Ling Zheng's shoulder was also frozen by the extreme freeze that had evolved from coldness, and his body was shrouded in dark blue ice.

"Bang!"

With a loud bang, Ling Zheng, who had lost his ability to control the sky, went straight from the sky to the valley, feeling that his limbs were almost about to be shattered, if he could grin his teeth, Ling Zheng felt that his expression now must be very exciting.

"Squeak!"

With a scream, the golden scale armor on the surface of the mouse's body stretched out in the dark blue ice, making a crisp "click" sound, and then the mouse screamed again, and the golden light flashed all over his body, shaking and scattering the layer of dark blue ice that enveloped his body.

Ling Zheng, who was also frozen, was a little happy when he saw this scene, because he was the same as the mouse before, his body was frozen, but his dantian and consciousness were still fine.

But after Ling Zheng forced out the True Yuan, he felt that this layer of dark blue ice seemed to be able to absorb his own attributeless True Yuan, and the more he stepped up to force out the True Yuan, the thicker the dark blue ice around his body deepened, and the chill that roamed around his body and constantly invaded his meridians became more and more intense.

If this trend is followed, if it doesn't take a cup of tea, Ling Zheng will be frozen in his meridians, and like everyone in this valley, he will become a frozen corpse.

Why can rats get out of the ice, but I can't?

At the critical moment, Ling Zheng was not much anxious, but recalled the mouse's previous moves.

After that, he imitated the previous actions of the mouse, first spreading his true element all over his body, and then using the power of his soul to manipulate his true element to condense into the shape of the scale armor on the mouse's body.

After doing this, Ling Zheng manipulated these true elements that had changed into the form of scale armor like the rat had just done, one by one.

"Click, click!"

A series of soft noises came out, and the ice that enveloped Ling Zheng's body instantly had countless tiny cracks.

Feeling the chill around his body quickly subside, Ling Zheng was overjoyed, and then the meridians in his body shook, and he controlled the attributeless True Yuan in his body to explode outward.

"Bang!"

There was another loud bang, and the dark blue ice around Ling Zheng's body all shattered. Seeing this, the mouse let out a burst of "squeak" sound full of joy, and then ran to Ling Zheng's shoulder.

"And thank you, little one. Ling Zheng said with some emotion, and then took out another piece of sauced beef from the storage ring and handed it to the mouse: "Reward you." ”

The mouse's eyes lit up, stretched out his little tongue and touched Tian Lingzheng's head, holding the sauce beef and gnawing heartlessly.

"Wait, it stands to reason that these people are much stronger than us, why are they freezing to death in this place, but we can live?" Ling Zheng asked in confusion as he looked at the hundreds of frozen corpses around him that still had a look of fear on their faces.

The rat who was munching on the sauce beef first pointed at himself and Ling Zheng, then pointed at the frozen corpses around him, and then shook his head.

Ling Zheng was a little puzzled: "You mean, the two of us are different from them?"

The rat nodded happily while holding the sauced beef, as if he was appreciative of Ling Zheng's ability to understand its meaning at once.

Ling Zheng stood and thought for a while, and then he was a little relieved.

The ghoul rat is an ancient xenomorph demon beast, and in terms of grade, it is much higher than the four-winged ghost centipede he killed at the beginning, so the ghoul rat not only has an extremely mysterious divinity, but its physical body is naturally not comparable to ordinary demon beasts.

As for Ling Zheng himself, there have not been a few attributeless spirit veins since ancient times, and after the ancient period, the inheritance of the attributeless spirit veins has been broken, and no one can say what kind of divinity and characteristics this physique has, even Ling Zheng himself is no exception.

In contrast, in the eyes of ordinary cultivators, it is a very rare mutated attribute spirit vein, and its appearance probability is "much higher" than that of a non-attribute spirit vein.

In other words, Ling Zheng and the rat both belonged to the outliers in the cultivation realm, and it was precisely for this reason that the two of them were not frozen to death in this strange valley.

Ling Zheng remembered the cough coming from the cave not far away, and felt that this valley should be far more than just freezing people to death. He was eager to see what was inside the cave, but as soon as he took a step, he was slapped on the head by the mouse, and listening to its shrill cry seemed to warn him, he immediately dispelled the idea.

After that, Ling Zheng took out the cross-domain teleportation array stone from his storage ring, and found that the array stone already had a faint light flickering, and it could barely be activated.

"This ghost domain is really full of secrets, although I want to explore them one by one, but the strength is really not enough. Ling Zheng muttered, "Hey, mouse, do you know what's in there?"

The mouse shook his head, but made an extremely terrifying expression.

Ling Zheng understood what the mouse meant, sighed lightly, and said, "Although the divinity of this array stone has not been fully restored, it is a cross-domain teleportation array stone after all, even if it is a part of the divinity, it should be enough for us to leave." ”

"If we can't leave, it's our fate. Ling Zheng asked, "Mouse, we will come back again in the future, let's say goodbye to this place first." ”

The mouse glanced at Ling Zheng, didn't shake his head or nodded, and continued to hold the sauce beef and nibble there.

After that, Ling Zheng crushed the cross-domain teleportation array stone in his hand.

In the flickering light, pieces of formation patterns flew out, and soon enveloped Ling Zheng and the mouse.

Just as his sight was about to disappear, Ling Zheng heard a soft cough again.

It sounded familiar to him. So, he turned his gaze to the dark cave, and found that in the cave, a pair of ice-blue eyes lit up.

In an instant, Ling Zheng was like being struck by lightning.

Because these eyes are so familiar, except for the different colors, that look, that gaze, is the same red eyes I saw in the burning crypt at the beginning!

A red-eyed monster that can freely shuttle through the flame space of the various layers of the incinerator crypt is surprising enough, and now there is a blue-eyed monster with eyes that are extremely similar to the red-eyed monster?

"Hey, ...... you?"

Ling Zheng was only halfway through his words, and his whole person turned into a ray of light and disappeared in an instant.

The pair of blue eyes that emerged from the dark and secluded cave were a little puzzled at first, and then they seemed to remember something, and the already fierce light in the blue eyes became even more intense, almost frightening people's courage.

"Unexpectedly...... Got you running away......"

Ling Zheng naturally didn't hear what the "blue-eyed monster" said, and he didn't feel the strong killing intent released by the other party, otherwise, he would definitely not have any intention of getting close to the other party.

With a flash of light, Ling Zheng and the rat suddenly appeared in a formation and planted them on the ground.

When he saw that the ground under him was still dark red, Ling Zheng's heart suddenly sank.

Dark red ground, could it be that I used the cross-domain teleportation array stone, and still didn't escape from this ghost domain?

Ling Zheng was in a daze, but the rat that landed on him let out a cry of joy. After that, the mouse happily climbed onto Ling Zheng's head and pointed in front of Ling Zheng.

Only then did Ling Zheng raise his head and see the area in the extreme distance shrouded in thick black clouds. He was stunned for a moment, and then laughed like a madman.

The mouse was startled, and jumped out like a golden ball, but he really couldn't understand why Ling Zheng seemed to be crazy.

"I, rat, do you know how lucky we are, just a little, almost we can't get out of this ghost domain. Ling Zheng got up from the ground, picked up the mouse, and put it on his shoulder: "Haha, if you don't die, there will be a blessing in the future, we have already come out." ”

"Let's go, brother, take you to eat beef!"

Although the mouse didn't understand what Ling Zheng was nervous about, he still heard the word "beef" very happily.

No wonder Ling Zheng was so excited. If this cross-domain teleportation array stone had teleported four or five miles less, he and the rat would still be in that forbidden land shrouded in black clouds, and God knows how many circles they would have to go around, how many wrongful roads they would take, and how many dangers they would encounter.

According to the above record in the "Xiuzhen Realm", the scope of the ghost domain is only defined in the area shrouded in black clouds, as long as the iconic black clouds cannot be seen overhead, it can be regarded as out of the ghost domain.

"When my cultivation is strong enough, I will definitely do it again. ”

Ling Zheng calmed down the excitement in his heart a little, and then said, "There are too many secrets here, and besides, we have to avenge your family, don't you say, rat?"

The rat nodded.

After that, Ling Zheng turned around and walked towards the outside of the Ghost Domain, although it was only less than a day from the time he entered the Ghost Domain to the time he left the Ghost Domain, he felt that this day was really the longest day he had ever lived in his life.

But not far away, Ling Zheng felt his scalp explode for no reason, and a cold air was bubbling from his back.

This feeling appeared very suddenly, Ling Zheng glanced at the mouse on his shoulder again, and found that it had turned its head and looked behind him, very distracted.

Ling Zheng knew that something might have happened behind him, and after turning around, he froze directly in place.

In that area shrouded in black clouds, at this moment, a huge queue of human figures gathered slowly walked out, pointing obliquely at the sky, and was skimming Ling Zheng's head.

The figures were not entities, they were all virtual shadows. Most of these phantoms were clad in ancient, but extremely tattered armor, with stiff expressions and hollow eyes, seemingly emotionless.

Yin soldiers?!

Ling Zheng's eyes widened, and he stared in a daze at the strange scene in front of him that most people would never see in their lives.
