A few days later, with a slight shaking, a gray hurricane appeared in front of the jade boat.

The rumbling sound was clearly audible at a distance, and when viewed up close, this gray hurricane connected the sky and the lost sea, like a raging storm giant, while constantly moving, stirring the sea in all directions, making the wind and clouds gather here for a while, and the water vapor filled the sky.

What's even more terrifying is that on the edge of this storm, there are still lightning and flames swimming, and the flame Xia Mu can still understand, it is nothing more than that the wind speed has reached a certain level, and the air friction is generated, as for the lightning, Xia Mu just can't understand it.

The lightning was very spiritual, sometimes wandering on the surface of the storm, sometimes burrowing into the storm, as if it had life, and even when he saw the jade boat that Xia Mu and the three of them were riding, he would transform into a fierce beast from a distance and grin at them, roaring incessantly.

"Although I know that there are often storm whirlpools in this lost sea, I just don't want to be encountered by us. Xia Mu and Mu Qingxian stood side by side at the bow of the boat, looking at the gray hurricane road that was getting closer and closer in front of them.

This gray hurricane was only felt from a distance, Xia Mu knew that the power was huge, and the immortal realm monks might not be able to get out of it if they were involved, if Xia Mu met it alone, then he could only run as far as he could. However, now that there is a half-step emperor powerhouse escorting him, he is not very afraid.

With a bang, I saw that Yuzhou plunged into the gray hurricane, and the spiritual light supported on the surface of the jade boat was extremely stable in front of this gray hurricane, without the slightest wavering, so that Xia Mu's hanging heart finally let go, although he had guessed that Yuzhou could withstand this gray hurricane, but he knew it, but when he really faced this gray hurricane, he couldn't help but be scared.

This shows that Xia Mu's Dao heart is not stable enough, and when facing the real great terror, he will still waver, although this vacillation is human nature, just like most mortals in the face of lions, tigers and beasts, how can they not be afraid.

Of course, cultivation is to constantly hone the Dao heart, and when Xia Mu's strength is improved to a certain level, looking back at this gray hurricane, I am afraid it will be a laugh.

Inside the hurricane, lightning continued to fall on the shield of the jade boat, bursting into a crackling sound, and around the jade boat, it was a gray patch, except for the high-speed rotating air, as if the outside sea water was isolated here, and could move with the hurricane, but could not enter the hurricane.

After looking at it for a long time, Xia Mu retracted his gaze and looked up at the lightning that kept falling overhead, his eyes flashed a few times in a row, and with the convergence of spiritual power, everything around him gradually slowed down in his eyes, as if the flow of time had changed, allowing him to see the trajectory of those lightning bolts clearly.

He saw the lightning strikes on the shield, splattering away, but soon converging in the distant void, as if it had an immortal body.

This frightened him, and he faintly thought of something.

Retracting his gaze, when Xia Mu released his divine thoughts, all the surrounding scenes were more clearly imprinted into his mind, this time Xia Mu felt more really, in these lightnings, there was a special will, and it was precisely because of the existence of this special will that those lightning bolts did not disappear after the collapse, but re-condensed in the distance.

This kind of will, Xia Mu vaguely felt in Aoki, it was a kind of will unique to immortal realm monks, but Xia Mu didn't expect that in these lightnings, there was also a faint sense of immortality, if the immortal realm Great Perfection monk could come to feel it at this time, it would definitely be of great help to his promotion to the immortal realm.

Of course, Xia Mu was just thinking about it, because he estimated that in such an environment, the Great Perfection Cultivator of the Immortal Realm might not be able to withstand the power of this hurricane, and before he could feel the meaning of immortality, everyone was already dead.

Taking a deep breath, Xia Mu slowly withdrew his thoughts.

Suddenly, a gray light flashed in front of his eyes, and he couldn't help but blurt out, "What is that?"

At that moment, Xia Mu felt that the gray light contained extremely strange fluctuations, which was definitely a rare treasure.

That is the "Lost Water", which is known as one of the three treasures of the Lost Sea. Before Mu Qingxian could answer, the figure in the void flashed, and Aoki's figure appeared outside the jade boat, only to see his palm leaning forward, and between the spiritual light illusions, a spiritual power hand appeared in the void, just a flick, it directly tore a hole in the hurricane, and then the spiritual power hand directly probed into it.

It didn't take long for the spiritual power big hand to be taken back by Aoki, but at this time, there was already an extra thing in the big hand, which was the gray light that flashed from Xia Mu's eyes before.

At this moment, this gray light was fleeing in the hands of the spiritual power, and it looked extremely flexible.

Seeing this gray light, Xia Mu was also shocked in his heart, he didn't expect them to be so lucky, they actually encountered the second treasure of the Lost Three Treasures, "Lost Water", and they didn't expect that this Lost Water was so miraculous, and it was born with extremely powerful spirituality, no wonder taking this water can help people achieve enlightenment.

"This thing is useless to me, so I'll give you half of it as a greeting gift. I saw Aoki's finger stroke, and the gray light instantly collapsed, revealing a fist-sized gray liquid inside, and then this gray liquid was split in two by Aoki and contained in two jade bottles, one was given to Mu Qingxian and the other was given to Xia Mu.

"Thank you, seniors. Xia Mu didn't expect Aoki to give him such a valuable gift, and while taking the jade bottle, he thanked him in his mouth.

"Okay, you can spend the rest of the time at your disposal, and I won't talk to you young people. Aoki nodded slightly, and then disappeared in a scattered manner.

And after Xia Mu and Mu Qingxian continued to chat for a while, they also returned to their respective secret rooms to retreat and cultivate.

The days of rushing were very boring, and there was nothing else to do except retreat. Gradually, Xia Mu and Mu Qingxian rarely came out and walked around, and they both fell into a long period of retreat.

A year later.

When Xia Mu had just withdrawn from the retreat, he suddenly felt a slight shock from the entire jade boat, and after a while, everything returned to normal again.

"The City of Seven Hell has arrived. At the same time, Aoki's voice sounded in Xia Mu's ears, and then Xia Mu only felt a wave of spatial fluctuations around him, and then the entire jade boat disappeared, and he himself appeared in the void, and not far from him were Mu Qingxian and Aoki.

In front of the three of them, a huge city stood.

"Is this still a city?" Xia Mu floated in mid-air, looking at the endless continent suspended in the void in front of him, his eyes widened.

Xia Mu was completely stunned.

He had seen a lot of cities, and even the war weapons built specifically for battle were not unheard of, but those cities were nothing compared to the one in front of him.

These Seven Hell Cities are not so much a city, but rather a continent.

"How big does this have to be?" Xia Mu said secretly.

Compared to the city floating in the void in front of you, the floating islands that surround it are like grains of rice.

"How is this going to pass?" Xia Mu was puzzled, they seemed to be very close to the Seven Prisons City now, but in fact they were extremely far away, if it was by flying, then Xia Mu might not be able to fly even if he flew for a lifetime.

"Xiao Xia, how do you feel about Seven Hell City?" Mu Qingxian on the side smiled.

"It's immeasurable, much bigger than all the cities I've ever seen combined. Xia Mu sighed, and then asked curiously: "But how are we going to get over?"

"Fly?"

Mu Qingxian shook his head and said, "If you just fly over like this, even if the Eternal Saint flies with all his might, it will take at least decades." ”

"So far?" Xia Mu was taken aback.

"I also listened to my mother. Mu Qingxian's tone paused slightly, and then he continued to speak: "If you want to enter the Seven Hell City, you can only teleport in through spatial teleportation, and there is no other way. Just now I said that it would take decades for the Eternal Saint to fly over, just to use an analogy, if you really want to fly over so directly, even if you are an Eternal Saint, you have to shed your skin if you don't die. ”

"Dangerous?" Xia Mu sighed lightly.

He didn't feel any danger in this void at all, but since Mu Qingxian had said so, there must be something.

"There are many dangers, some are natural, some are laid down by our seven-colored hell for generations, I heard my mother say that some dangers are difficult for her to get out alive even if she falls into them, so when I was very young, she warned me not to run around and play in this void. Mu Qingxian said.

Her voice fell, and Aoki, who had been closing her eyes on the side, suddenly opened her eyes and said, "Spatial teleportation has begun......"

Before Aoki finished speaking, a huge spatial force enveloped the three of them, and they instantly escaped into the depths of space.

When Xia Mu came back to his senses, the three of them had already appeared on a huge altar.

"Uh, how did we get in?" Xia Mu looked at the beautiful buildings around him, although he understood that the three of them might have entered the Seven Hell City, but he was a little confused about the means of entering.

"That's what I said just now, Uncle Aoki has been closing his eyes to communicate with the spirit of the city protector of the Seven Prisons City, once the identity is confirmed, the spirit of the city guard will open the altar in the city and extradite us from the void. Mu Qingxian explained.

"Oh, by the way, the Spirit of the City Protector is an adult who is in charge of the entire Seven Hell City, and you can think of it as a treasure spirit. ”

"Hmm. Xia Mu nodded.

Even the Immortal Realm cultivators can refine the Acquired Spirit Treasure, and use the means of the seven-colored hell to refine a city protection spirit, which is not a difficult thing to think about, although this city is incredibly large, but Xia Mu slowly accepted it after experiencing the initial shock.

Call!

Xia Mu and Mu Qingxian followed Aoki down the altar.
