If you want to say that the Sunset Grand Canyon is the most, it is not a tree or a mountain, and the people of Black Pupil and Fengdu will tell you in unison, it is the isthmus.

Yes, think about it, where is the original capital of the dead, and now the city of angels, in the middle of the isthmus. The Grand Canyon of the Sunset is full of large and small isthmuses, except for the hurricane pass, where everything else is the same.

Zhou Yi ran all the way with Xiao Yiran on his back, and he couldn't get rid of Mo Liuqi behind him, from Fengdu City to the Sunset Grand Canyon, a distance of thousands of miles, which made Xiao Yiran's heart more and more depressed.

"Brother Zhou, there is an isthmus entrance in front, can you get in?" Lying on Zhou Yi's back, her vision was better than Zhou Yi's, and she saw at a glance that there was a rather large isthmus entrance in front of her, although it was not as big as the isthmus entrance in the City of Angels, but it was relatively large.

"Well, go in, there is no good terrain outside here to get rid of the old monster behind!" Zhou Yi responded briefly, and his body went straight into the isthmus.

With this jump, Xiao Yiran's heart suddenly became nervous.

Although it is possible for the Isthmus to get rid of Molyuch's pursuit, it is also very risky to jump into it rashly.

No one knows how the Sunset Grand Canyon was formed, spanning the Black Pupil Continent and cutting off the entire continent from east to west. Some of these isthmuses in the canyon are bottomless, some are connected to each other, and most of them are filled with many time and space cracks, and if you don't pay attention to it, you may die.

"Brother Zhou, be careful, the entrance to this isthmus is overgrown with weeds, it is very likely that no one has entered, there are spatial cracks in it!" Xiao Yiran just looked carefully at the entrance, and it seemed that there was no human trace, it was very likely that it was an isthmus full of spatial cracks.

Without her needing to say, Zhou Yi had already sensed that something was wrong, his spiritual power was strong, and just a moment of probing, he found a lot of spatial cracks. These cracks are extremely dangerous, if you don't notice it, you can cut off your limbs or die, and a drop of cold sweat will crawl on the door of Zhou Yi's brain in an instant.

"You hold me tight, we have to rush over!" There is a trap in front, and there is Mo Liuqi in the back, and now he has to force himself to break through.

"Hmm!" Xiao Yiran replied softly, she also understood the current shape, and she didn't dare to distract Zhou Yi at all.

Radiating the spiritual power out of a distance of 100 meters in an echo mode, carefully probing the unusual spatial fluctuations in front of him, wherever there is no return to the spiritual fluctuations, there may be spatial cracks, Zhou Yi's figure was so cautious, like a civet cat, it flickered and moved, and disappeared into the isthmus after a while.

As soon as their figures disappeared, Molyuch appeared at the entrance of the isthmus, the Necromancy God, who was also very powerful in terms of spiritual power, but in terms of physical strength, it was a different story.

The spatial rift in this isthmus is also a big trouble for him. If you are careless, maybe this body will also be damaged.

Mo Liuqi's eyes were full of fierce flames, he regretted it at this time, he had known that there were such places in the Sunset Grand Canyon, and he would not let Zhou Yi escape here if he said anything. The key is that he is an outsider, and he is not familiar with the situation of the Black Pupil Star at all, so this can be regarded as an unintentional mistake.

"Huh!" Divine Thoughts swept out, "Huh!?", and then the soul was suffocated, and these spatial cracks did not hurt Divine Thoughts a lot.

He swept out like this, and when he touched the spatial crack, there would always be a lot of divine thoughts swallowed by the spatial crack, and the accumulation was enough for him to suffer! Of course, the loss of Zhou Yi's spiritual power was not a small amount, but this was not the time to feel distressed.

Relatively speaking, Mo Liuqi's speed at this time was not as good as Zhou Yi's, and the distance between the two began to widen.

After all, the Necromancer God, even if the divine thoughts such as spiritual power are incomparably powerful, are only good at undead magic, and undead magic is not good at probing, so he has to use stupid methods to violently probe spatial cracks. In addition, the strong man of the law system did not pay attention to the cultivation of the body, so he did not dare to touch the spatial crack lightly, so he had to slowly enter the isthmus step by step.

Zhou Yi imitated the echo wave of the bat to emit spiritual power, the consumption was far less than that of Mo Liuqi, and the efficiency was much higher, and after Zhou Yi's body was tempered by the "Nine Turns Yuan Gong", the flexibility of the martial artist's body was far stronger than Mo Liuqi's, and the flexibility was much higher when passing through the isthmus with dense spatial cracks.

The entrance to this isthmus is very large, indicating that the width and depth of the isthmus are very long, and after two hours, Zhou Yi and Xiao Yiran have completely disappeared into the scope of Mo Liuqi's divine perception.

"Damn! This treacherous thief, let this seat catch it, you must pull out your soul and torture it severely, this seat will let you survive but not die!" Mo Liuqi had only advanced about two kilometers for two hours, and at this time he could not laugh at all, and only a thick resentment was left in his heart.

"Whew!" With a long sigh, Zhou Yi finally breathed a sigh of relief, the two of them had already passed through the guò spatial crack area, and two branch entrances appeared in front of them, and after a cursory exploration, they could find that there were no spatial cracks in these two holes.

"The same, which side to choose?" Zhou Yi asked, staring at the two openings in front of him.

"Huh!?...... I don't know either!" Xiao Yiran was also dumbfounded.

"The one on the left is a little closer to the entrance we came in, it doesn't seem to be very safe, and the one on the right is facing down, and I don't know if it will lead all the way to the bottom of the cave, if it's a dead end, it's a tragedy for the two of us!"

"Brother Zhou, if the direction is too close, it may be noticed by that person, so it's better to continue down!?" Xiao Yiran said hesitantly.

"Well, yes, this guy is a god-level powerhouse, and he is a powerhouse of the law system, and his spiritual power must be very strong. If we go to the left, maybe we will be perceived by him again, so we will choose the right side, and we will die in the sky, no matter what! It's this way!"

Although he had just explored and found no spatial cracks, he did not dare to be careless at all, and always radiated his spiritual power a hundred meters ahead to avoid capsizing in the gutter.

An hour after the two of them passed, Molyuch also came here, and looking at the two holes in front of him, he only thought about it for a moment, and then followed their footsteps and chose the hole on the right. Of course, the remnants of their breath also indicate that they chose the right side.

More than an hour later, Zhou Yi and Xiao Yiran came to a stone room the size of a football field again, this time, with the hole they came out, there were a total of six holes in the stone room.

Zhou Yi was completely dumbfounded, how to choose this!?

"Ah!?What should I do about this?Just now this passage turned left and right, we don't know what direction it is now!" Xiao Yiran exclaimed.

"No matter, just keep choosing the first hole in the right hand! Anyway, we have lost our direction, so we just go all the way to the dark!" Thinking of this, Zhou Yi walked towards the entrance of the cave with her on his back.

As soon as he walked to the entrance of the cave, he suddenly had a realization in his heart, and immediately carried Xiao Yiran on his back and unfolded his body, walking through all five caves, each cave was about 100 meters deep and then exited, and then entered the originally selected cave entrance.

"Brother Zhou, what are you doing?" Zhou Yi's strange behavior made Xiao Yiran confused.

"You don't know, that guy is a necromancer, and he is the most sensitive to the breath of the living, and I go 100 meters deep in each hole, so let that guy waste some time!"

"Hee-hee, Brother Zhou, you are so bad!"

"It's not that I'm bad, it's that guy is strong, as long as he can create a little trouble, he can't miss any opportunity! Hehe! Let him look for it!" Zhou Yi pouted and said, and in the end, he also chuckled.

After speaking, he glanced behind him, but there was no movement, and he hurriedly plunged into the cave.

Sure enough, an hour later, Mo Liuqi's figure appeared, and when he was about to draw a scoop with a gourd and choose a cave with the breath of Zhou Yi and Xiao Yiran to enter, he was stunned to find that all the cave entrances were there.

Furious for a moment, the momentum of the god-level powerhouse in his body suddenly lost control, and the black cloak on his body was smashed into pieces by the energy, revealing his dark black skeleton body.

Unfortunately for him, he chose to start from the hole on the left, and as a result, he ran through all five holes, only to find that if he chose to start from the right, he wouldn't have to run the other holes at all.

Mo Liuqi felt that his soul was unstable for a while, but at this time he was angry, and he only thought that it was because of his feelings, so he didn't care too much about it, and chased after him.

Another hour passed, and a stone chamber appeared in front of Zhou Yi and the others again, twice the size of the previous stone chamber, and twelve appeared at the entrance of the cave.

"Brother Zhou, something is wrong with the situation!" Xiao Yiran was delicate and found that the isthmus was a little weird.

"Well, the first chamber is only half the size of the second, and there are three openings in total, and the second chamber is twice as large as the first, and the openings are six, and the third chamber is twice the size of the second, and the openings are doubled.

This situation is regular, and it can never be a natural occurrence, nor can it be a coincidence. Here, there must be some secrets, I don't know what is going on below?" The relaxed look on Zhou Yi's face turned solemn.

"Brother Zhou, the entrance we chose, the first time we chose the right, the last time we still chose the right, this time it is better to choose the left, see what the difference?" Xiao Yiran pondered for a moment and then said.

When Zhou Yi heard this, he immediately understood what she meant.

It may be a coincidence that each time you select the first hole on the right, the next stone chamber will appear with a double opening. If you choose the hole on the left, if there is a stone chamber behind, and the hole in the stone chamber is still double, then the matter is not what you guessed.

For example, the first stone chamber has three openings, and the next floor is not one stone chamber with six openings, but three stone chambers with eighteen openings, and this floor is eighteen stone chambers with two hundred and sixteen openings.

And what about the next level?

Thinking of this, he felt his scalp tingle a little.
