Compared with the demon cities in other places, Luo'an City is not large, occupying dozens of miles in a circle. The city is not particularly bustling and lively, but it is orderly, and at a glance, all the streets are straight, and there is not a single detour in sight. The houses are also of similar height, divided by the streets, like tofu cubes cut into many pieces, boxy and neat.

However, the walls of Luo'an City are surprisingly high, which I am afraid few cities can compare with it. Almost towering into the sky, standing on the city walls and looking down, the monsters in the city are like ants.

Around the city wall, there are a large number of demon clan masters who are responsible for guarding, and if they want to fly in and out of the air, there is only one way to die. The only gate of the city is on the east side, guarded by Nai He Tianzun.

At this moment, Nai Tianzun was sitting in the city tower, paying close attention to the movements below.

He doesn't need to go down to check in person, he just needs to release the domain, shroud the city gate, and then urge the law of memory, then all the people who pass through the city gate will be read by him.

Whether it's someone who has done something bad in the city and wants to get out of the city, or someone who has done something bad outside the city and wants to enter the city, don't try to hide it from Tianzun. Because of this, the King of the Fifth Realm would rest assured that he would sit in the city tower.

I don't know if it's because I read too many memories, but Tianzun's head is very big, and the back of his head is high and bulging, like a hornet's nest, bare on it, and there is not a single hair.

However, Tianzun's face is also quite ugly, and his facial features seem to have been forcefully blended together by someone, almost squeezed together, looking quite hideous.

On weekdays, Tianzun doesn't need to read everyone's memories from beginning to end, only needs to read the latest part of the memory, because the people who enter and leave Luo'an City are all monsters in the vicinity, and they come and go, but Tianzun already knows everything about them.

But after the recent incident in the Broken Soul Mountain Range, an order was issued from above, but Tianzun should strictly control it, and not be taken advantage of by the young people. As a result, Tianzun had no choice but to read all the memories from birth to the present, which also caused the team at the city gate to enter and exit relatively slowly.

Memories poured into Nai He Tianzun's mind, there were both ups and downs, as well as all kinds of filth, but He Tianzun had long been numb, and his expression did not change at all.

Most of the memories are familiar to Nai He Tianzun, and the fresh memories are also dull and unremarkable, and they can't attract the attention of Nai He Tianzun. But suddenly, there was a memory in it, but it made Nai He Tianzun pay attention.

"You also know that when Yunfeng bordered my Kullying Ridge, there was a heavy rain a few days ago, and when the place where Yunfeng bordered Kullow Ridge was washed away by heavy water, the two of us happened to go over to check at the same time, and we ran into it. ”

"In the place where it collapsed, we found an underground cave, the cave is too deep, and we don't know if there is danger below, we discussed it, and decided to call you, let's go down and investigate together......

The master of memory is the Thread Demon of Black Wind Valley, and the person who speaks is the Dog Demon of Silent Ridge.

"At the junction of Silent Ridge and Dangyun Peak, there is an underground cave?" Tianzun frowned slightly.

However, Tianzun has also been to that area, and the only impression is that the aura is thin and unsuitable for living, unless it is those monsters who are relatively down-and-out and have nowhere to stay. For the appearance of an underground cave in that place, Tianzun didn't have any expectations, just a little curious, and continued to read.

"Hey, what kind of water is this?"

"It's strange, it's so strange! I can't even pick up this kind of water. There is such water in the world!"

"What's wrong with you?"

"My head...... It hurts me...... Spring...... Ran into my head...... Fast...... Hurry up and help me get it out......"

Seeing this, Tianzun's face changed greatly, and Huo Di stood up.

He controls the laws of memory, can read the memories of others, if he is knowledgeable, I am afraid that no one in the world can compare to him, the line demon, the dog demon and the needle demon do not recognize that kind of spring water, but Tianzun does.

"Spiritual water!"

However, Tianzun's face was full of shock, and he muttered to himself.

He never imagined that he would discover such an astonishing secret. The stronger the divine soul, the more powerful his law is, and the more durable it is, but the cultivation of the divine soul is very troublesome, but Tianzun has stayed in the fifth realm so far, and it is difficult to break through the shackles.

But with spiritual water it's different. Spiritual water can be directly refined and integrated into the divine soul, greatly enhancing the divine soul, which is a rare shortcut in the cultivation of the divine soul. However, Tianzun had seen the legend of the spiritual water in other people's memories, but he had never seen it with his own eyes, and he had always thought it was just an ethereal rumor, but he didn't expect it to be true.

In this world, there really is spiritual water!

The soul of the needle demon is too weak to withstand the erosion of the spiritual water, so it faints to death, which to a certain extent also confirms the strength of the spiritual water.

However, Tianzun's breathing became a little short.

His instinctive reaction was to tell the King of the Fifth Realm, but after thinking about it, he didn't move. Once it is stabbed to the Fifth Realm King, although it is a great achievement, the spiritual water left to Nai He Tianzun in the end will probably not exceed three drops.

However, Tianzun is of course loyal to the Fifth Realm King, but he is even more loyal to himself, if his own strength is not strong enough, the Fifth Realm King may not look down on him.

"If I can refine all the spiritual water in that spring, it is possible for the divine soul to break through at least one realm, or even two realms!"

He thought about it and planned to call the Wire Demon up for questioning, but he was worried that it would leak out, so he had to give up. After all, the line demon didn't recognize the spiritual water at all, and thought it was a kind of poisonous water, so he didn't dare to touch it again, if he specially called it over to ask, it would make the line demon have other ideas.

Moreover, there are a lot of monsters on the upper floor of this city, and the line demon is called to come up, and it will be a little impressive in the eyes of others, although I don't know the reason, but after the fact, it is a handle.

"This matter must be kept secret!" However, Tianzun secretly made up his mind.

He remained silent, and the Wire Devil entered the city as if nothing had happened. Not long after, the line demon went out of the city, and he was accompanied by the famous doctor medicine demon in Luo'an City, and hurriedly went to the direction of Dangyun Peak.

However, Tianzun's heart was clear and calm.

Since the line demon is in a hurry to seek medical treatment for the needle demon, he will not enter the underground cave again in a short period of time, which is the best news for Nai He Tianzun. It is easy for him to kill people and kill people, and it is easy to get rid of the Thread Demon, the Needle Demon, the Dog Demon, and the Medicine Demon, but the problem is that it is easy to arouse suspicion.

The Thread Demon, the Needle Demon, and the Dog Demon live in the wilderness, and if they die, they may not cause much movement, but the Medicine Demon is still quite famous in Luo'an City. The people close to the medicine demon must know that he went to Dangyun Peak, and if he doesn't return, he will go to Dangyun Peak to check, and it is easy to find out that underground cave.

Therefore, the road of killing people and destroying mouths will not work.

However, Tianzun needs a foolproof strategy.

It was late at night.

The gates closed slowly with a heavy thud.

However, Tianzun did not go home as usual, but still stayed in the city tower. What made him feel a little strange was that the medicine demon had been gone for most of the day and had not returned yet.

"Could it be that something has changed?"

However, Tianzun was a little vigilant, but he found another explanation for himself.

"The needle demon was eroded by the spiritual water, and although the medicine demon claimed to be cured by the medicine, I am afraid that it will not be so easy to cure her, so I can only stay in Dangyun Peak. ”

Thinking like this, Tianzun's vigilance was retracted, and he looked forward to the spiritual water even more. He has seen the methods of the medicine demon, and there are indeed two times, since the medicine demon can't be cured for a day, it means that the spiritual water is indeed extraordinary, so that the medicine demon is helpless.

"My lord, the city gate is closed, aren't you going home?" said a slender youkai in the doorway.

He is Nai He Tianzun's deputy, and he is also the most trusted subordinate, named Embroidery Demon.

However, Tianzun pondered for a while, but still didn't tell the secret of the spiritual water, and said lightly: "I have something to do, and I need to go out." ”

"Do you need to be accompanied by a subordinate?"

However, Tianzun shook his head and said, "No need, you stay here and wait for me to come back." ”

"Yes. ”

However, Tianzun's body flickered, turned into a light wind, floated down the city tower, and flew towards the east. That's the opposite direction to when Yunfeng is in the opposite direction. The demon clan masters on the city wall all saw the whereabouts of Nai He Tianzun.

When Luo Ancheng behind him could no longer be seen, Tianzun turned around and flew south, flying hundreds of miles, and then headed west. He was cautious by nature and didn't want people to know where he went, so he deliberately made a big circle, and when he came back, he had to go around again, although it was a little troublesome, but safety first.

If people knew that he had obtained the spiritual water, I don't know how much trouble would come to the door, and even the Fifth Realm King would ask about it, but Tianzun would not be able to bear it.

In the distance, I saw that the moon and stars were scarce, and a lone peak stood under the sky, and the peak was pitch black, which was when the cloud peak.

"Strange, why is there no light on the mountain?" Tianzun frowned slightly.

It stands to reason that since the line demon has invited the medicine demon to come over and heal the needle demon, the medicine demon has not returned yet, and the mountain should not be dark.

"Could it be that you have already slept?" Tianzun secretly guessed.

Although it was not impossible, he always felt that something was wrong.

"Or did they go to that underground cavern again?"

However, Tianzun's heart jumped, and a wave of anger surged into his heart, the spiritual water in the underground cave had already been regarded by him as a thing in his bag, how could he allow others to touch it?

However, out of caution, Tianzun still did not rush into the cave, but first went to Yunfeng to find out.

When the cloud peak was quiet, the courtyard gate was hidden.

However, Tianzun sensed a faint breath in the house, so he flew up to the roof and lifted the roof tiles to look down.
