After the two met, they signaled to each other, and without a trace of delay, they recognized the direction, stepped on the flying sword, and flew forward quickly again. The cultivation of the two of them is not low, and the speed is naturally extremely fast. In a few flashes, it disappeared into the passage.

Half a day later, the two came to a cave dozens of zhang in size.

Stopped, looking at the cave full of dark mist in front of him, Zhou Nan frowned.

This cave is not big, but it is not small. But Zhou Nan was very uncomfortable. Here, he felt like he was staying in the Valley of the Wind, and his divine thoughts were greatly suppressed. Even if he was fully engaged, he could only measure a distance of more than a hundred meters. With a dazed expression, Zhou Nan solemnly turned on the Heavenly Eye Technique, but the green light in his eyes only flashed a few times, and he sighed and stopped helplessly.

Seeing Zhou Nan do this, the monk surnamed Zou smiled slightly and said lightly, "Zhou Daoyou, you better save some mana! The passage to the second floor of the law enforcement prison is here." Some underground yin qi floated up along the passage and converged into a black mist. Although these yin qi black fogs do not cause any harm to our foundation building period monks, they can greatly limit our divine thoughts, vision, and disgustingness. ”

Hearing this, Zhou Nan nodded thoughtfully. followed the monk surnamed Zou, turned into two blue lights, and flew into the black mist. As soon as Poo entered the black mist, Zhou Nan felt that the world was quiet. Everything around me, I can't see anything clearly.

In this state, Zhou Nan could only be cautious and vigilant, while following the monk surnamed Zou, along a pitch-black passage about ten zhang in size, pinning his safety on his senses, and flying straight underground.

A quarter of an hour later, Zhou Nan only felt a light in front of him, and then came back to his senses, and quickly stabilized the downward momentum. Squinting his eyes, he took in everything in front of him.

The field of vision in front of you is extremely open, and there is no end in sight. But not far away, it was blocked by a thick black fog, and it was impossible to see it really. Nearby, there is some green light, which is very permeable. But overall, the view is much better than before.

On the ground, there are undulating hills, one after the other, stretching into the distance. It's not that there are a few zombies with white hair all over their bodies, but they are not sane, standing on the ground, and they keep yelling at Zhou Nan and the others.

"Tsk, it's really spectacular! I can't imagine that there is such a world realm underground. Staring at everything in front of him, Zhou Nan kept rolling his eyes and couldn't help but admire.

"Hehe, it's the first time Zhou Daoyou has come down to the second floor, and it's not too strange to see such a scene. When Zou was imprisoned in a law enforcement prison, when he went down to the second floor, he was as surprised as Zhou Daoyou. Smiling at Zhou Nan, the monk surnamed Zou said with emotion.

"What kind of place is this, there is such a heavy yin qi, and there is such a large space, it is really extraordinary. Zhou Nan retracted his gaze, stretched out his hand and grabbed a handful of black mist floating by his side, and asked lightly.

Listening to those Taoist friends who have been in the prison for hundreds of years, it seems that this law enforcement prison was specially built to suppress the space here and prevent zombies from causing chaos. The Xuanhuo Sect is a small place. Zou had heard that those guys from the Corpse Puppet Sect even moved the entire sect underground, guarding the zombies while cultivating. The monk surnamed Zou said slowly, like a knowledgeable Confucian, and easily gave Zhou Nan a reasonable explanation.

"It's possible. Otherwise, the Xuanhuo Sect would not have built the law enforcement prison to such a ghost place, but if it was really for the sake of those corpse crystals, I really didn't believe it. Although these corpse crystals have some effect, they are not attractive in the eyes of those ancestors of the Dan Period. The Xuanhuo Sect will never do thankless things, right?" seemed to agree with the explanation of the monk surnamed Zou, and Zhou Nan nodded.

"Let's go, we'll talk about it later. Although there are not many zombies in the foundation building period on this second floor, staying in one location for a long time will still attract their attention. The monk surnamed Zou said lightly, and led Zhou Nan and flew forward.

Half a day later, in a small valley, Zhou Nan and the others fell. Ignoring the dozens of white-haired zombies in front of him, he walked forward briskly while killing.

casually threw out a low-grade flying sword magic weapon, cut off the head of a white-haired zombie, and collected the corpse crystal, Zhou Nan stared at the flying sword that already had a gap, and frowned, "Although the level of these zombies is not high, the hardness of this body is really unusual, and it is more than three or four percent stronger than similar people in the outside world." ”

"Hehe, Zhou Daoyou is really careful, and he doesn't even let go of such details. Hearing this, the monk surnamed Zou smiled.

"No way, who made this place so weird, although we are already foundation building monks, but we are not far from the point of ignoring these dangers, it is always good to be careful. Ignoring the words of the monk surnamed Zou, Zhou Nan said to himself.

After walking for a while, Zhou Nan looked at the monk surnamed Zou, who was still tepid, frowning, a little dissatisfied. "Zou Daoyou, you have already arrived here, don't you plan to say the purpose of this trip?"

Turning his head and glancing at Zhou Nan, the monk surnamed Zou smiled and said, "Why is Daoyou Zhou so anxious, we have all said before, as long as Daoyou helps Zou achieve his goal, that precious corpse crystal of the Great Perfection level of foundation building is Daoyou's." ”

"Hehe, having said that, but I have been on the road for almost a day, and I have already gone deep into the depths of the second floor, which is a little inconsistent with what Zou Daoyou said before!" Zhou Nan didn't change his attention, and still insisted on saying.

"Hey, since Zhou Daoyou said so, then Zou Mou will not take out some things, but it is not easy to do. Shaking his head helplessly, the monk surnamed Zou threw out a palm-sized white jade compass and put it in front of Zhou Nan's eyes.

This compass is not large, but the color is as crystal clear as mutton fat, and it exudes a faint fluorescence. The compass is engraved with some strange symbols. In the center, there are three hands of different lengths, which are constantly rotating, making a 'zizz' grinding sound. In each of the four directions of the compass, there is a bead the size of a dragon's eye, which is different in color and looks very strange.

As soon as he saw this white jade compass, Zhou Nan's face changed suddenly, and he shouted in a lost voice, "This is a high-grade spirit weapon, a spirit search compass." ”

"Hehe, Zhou Daoyou is really well-informed, and even this soul compass knows the Tao. Seeing Zhou Nan's surprised expression, the monk surnamed Zou said a little proudly.

came back to his senses and smiled bitterly, Zhou Nan spread his hands and said helplessly, "Zou Daoyou is really blessed, I didn't expect this soul search compass that has been lost for hundreds of years to be in the hands of Daoyou." ”

Zhou Daoyou praised it, Zou just got it by luck. Now Zhou Daoyou believes in Zou's words, for that corpse king flower, if there is no soul compass, Zou would not have gotten this news. The monk surnamed Zou breathed a sigh of relief.

"In that case, let's speed up our pace, and find the black zombie in the early stage of foundation building earlier, so that we can finish it quickly. Zhou Nan just urged, waved his hand to kill a white-haired zombie, and walked forward calmly.

But in his heart, he became more cautious about the vigilance of the monk surnamed Zou.

Originally, the cooperation between him and the monk surnamed Zou was only to help him kill a black zombie wandering on the second floor, and get the corpse king flower on its body, so that he could get a foundation building Great Perfection level reward.

With Zhou Nan's original intention, this should not be a difficult thing. Besides, he needed this corpse crystal too. But I didn't expect that after going underground for so long, I still didn't find the slightest trace of the black zombie. And the monk surnamed Zou didn't mention anything about it, but just hurried away. With such a strange behavior, Zhou Nan couldn't sit still, so he had to ask bluntly for his own safety.

But he didn't expect that the monk surnamed Zou would use the soul compass to block his words, and in order not to tear his face, Zhou Nan had no choice but to continue to cooperate. Besides, he still believes in the rumored soul compass.

After another half a day, the two of them came to a huge canyon. It took a lot of effort to join forces to kill a black zombie in the early stage of foundation building, and they went deep into the inner perimeter of the canyon.

Not long after leaving, a flash of joy flashed on the face of the monk surnamed Zou, and he hurriedly took out the spirit search compass and searched the canyon continuously. Looking at the suddenly white and generous spirit search compass, Zhou Nan also breathed a sigh of relief. After all, after staying on this second floor for two days, even if the cultivation is strong, there is a trace of boredom.

Walking forward briskly, the monk surnamed Zou looked at the spirit compass that was constantly flashing with white light and the pointer was trembling, and suddenly shouted loudly, "Zhou Daoyou, come here, the black zombie has been found." ”

"Oh. Zhou Nan was shocked, and also stepped forward, and hurriedly looked at it.

I saw that on the stone wall on the side of the canyon, there were a lot of rattans. Under the rattan, a crack more than ten zhang wide suddenly appeared, deep into the stone wall. Inside the crack, a thick black mist was constantly spewed out, blocking Zhou Nan's vision.

But Zhou Nan still clearly felt a huge aura, hidden within this crack. This aura was far more powerful than the black stiff he had encountered in the deep mountains before, and it was enough to have the cultivation in the late stage of foundation building.

His face froze, Zhou Nan turned his head to look at the monk surnamed Zou, and said coldly, "Zou Daoyou, this is the black stiff in the early stage of foundation building that you said?"

Hearing this, the monk surnamed Zou looked stunned, but then smiled treacherously, "Zhou Daoyou, don't worry, when I encountered this black zombie five years ago, this guy was indeed a cultivator in the early stage of foundation building. But Zou didn't know how to mention the cultivation in the later stage of foundation building in this mere five years. I didn't mean to deceive Daoyou, and I hope that Daoyou Zhou will forgive me. ”
