Chapter 785: Immortal Domain Stygian Water (Ask for Subscription!) ）

The cave is very large and very high, and the walls of the cave are all blue boulders, which are all integrated, and there is no trace of artificiality. However, if you look closely, you can still see the simple patterns and text carved out of it with a knife and axe, and it is clear that someone has been here before.

Entering the cave, Xu Yinglong actually felt a thick aura, but when he tried to absorb these aura, he found that he couldn't absorb it at all, which made Xu Yinglong feel surprised.

Could it be that this is actually a forbidden spirit space? The so-called forbidden spirit space is to prohibit all spiritual energy from entering, and after the people outside enter it, they will not get any replenishment at all except for the spirit yuan they have reserved.

However, the Forbidden Spirit Great Array is a very advanced formation, even many high-level immortals in the Nine Heavens Immortal Realm may not be, let alone that this is just a mortal plane.

But when Xu Yinglong went deep into the cave, he found that the cave here was full of forks, big holes and small holes, and there were small holes in the small holes, and the holes were connected, forming a natural magic circle. What surprised Xu Yinglong even more was that this formation was not only a forbidden spirit formation, but also had the functions of a phantom formation, a killing formation, and a guardian formation, which was simply a super hybrid formation.

After seeing this formation, Xu Yinglong couldn't help but sigh that Xu Hongling's life was really big, such a powerful mixed formation, even if he was now, he couldn't crack it in a while. Not to mention Xu Hongling, a weak woman, you must know that when Xu Yinglong first met Xu Hongling, she was just a garbage monk in the early stage of dark energy, and it was definitely a miracle that she could successfully pass this formation and leave alive.

Xu Yinglong took a closer look. There was no trace of artificial arrangement in this mixed formation, and it seemed to be really a natural formation. But Xu Yinglong didn't believe that the naturally formed formation would be so powerful. In the Nine Heavens Immortal Realm, there are not no naturally formed formations, but they are all simple phantom formations or guardian formations. There are very few such mixed formations.

Of course, after seeing this formation, Xu Yinglong couldn't help but have a trace of expectation for this immortal treasure in his heart, because the place where the formation is naturally formed must have real heavenly treasures, the formation is not broken, and the spiritual treasure is not lost.

But it's just a glimmer of expectation, after all, this formation has been in operation for I don't know how many years, and now the earth is in full swing, the environment of heaven and earth has changed dramatically, and the power of the formation can still be exerted How many layers is really uncertain. There must be a reason why Xu Hongling was able to enter and exit this cave smoothly before. Someone may have already taken the treasure inside.

Although the formation is very advanced, it is nothing in the eyes of Xu Yinglong, the formation master. After a lot of hard work, Xu Yinglong quickly figured out the operation rules of this large array.

The subtlety of the formation lies in the law of operation, if you don't know the law of operation, if you want to break the formation, it is like doing things with brute force, and it must be half the effort. But once you figure out the rules of its operation, then breaking the formation is twice the result with half the effort.

The cave is very deep, and there are many forks, although Xu Yinglong has figured out the operation law of this big array, he still walked for nearly two hours before he can be regarded as getting out of the cave.

Outside the cave, you will see a huge underground space. Because the light was very dim, and Xu Yinglong's divine sense was suppressed, he couldn't see how big this space was at all. But based on Xu Yinglong's experience, this underground space must be not small. If he guessed correctly, this should already be the interior of the earth.

Less than two kilometers out of the cave, there was a huge underground river, with a faint glimmer of light from somewhere. Xu Yinglong took a closer look at this underground river and found that although the water of this river was not very turbulent. But it gave him a very strange feeling.

Xu Yinglong did not rush to cross the river, but found a branch from the shore. Then gently throw it into the river. I saw that the branches of the trees sank when they entered the water, and they did not stay.

Xu Hongling was dumbfounded, she didn't expect this river to be so weird, it is said that it is impossible for dry branches to sink to the bottom of the water, but throwing it into this river is like throwing an iron block.

"The River"

Xu Yinglong said with a solemn expression: "This is not ordinary water, but immortal dark water that is not common in the fairy world. ”

"Immortal Dark Water? What kind of water is that? Xu Hongling asked in surprise.

Xu Yinglong replied in a deep voice: "The immortal realm dark water is the yin water that is transformed into the bodies and souls of hundreds of millions of immortals after death, and if there is more yin water like this, the river styx will be formed. ”

"Body and soul incarnate? How many people do you have to die if the river is so full? Xu Hongling asked in horror.

Xu Yinglong shook his head and said: "I don't know much about this, the immortal realm is not common even in the immortal realm, but it is very common in the underworld!" As for such a river of Styx, it is even more mysterious, it can only be seen in those ghost domains with extremely heavy yin energy, but I didn't expect to be able to see it in this place. ”

Speaking of this, Xu Yinglong couldn't help but ask curiously: "By the way, how did you cross this Styx last time?" ”

"I don't know, that time I was like a ghost, after entering this cave, I was dazed, and when I woke up, I found that I was already in a large primeval forest!" Xu Hongling replied.

After answering Xu Yinglong's words, Xu Hongling asked rhetorically: "Don't you know how to fly, I think this river is only one or two kilometers wide, doesn't it fly over in minutes?" ”

Xu Yinglong shook his head and said: "The immortal realm is one of the most vicious waters in heaven and earth. Moreover, there is a strange power under the underworld, and no immortals, Buddhas, ghosts, demons, beasts, and demons can cross over it. ”

"So what are we going to do?" Xu Hongling asked with a frown.

Xu Yinglong thought for a while and said: "The dark water is difficult to cross, but it also depends on the situation, although the earth, rocks and even wood cannot float on the river, there is one thing in the district that can enter the river without sinking!" ”

"What's that?"

"Human bones!"

"What?"

Seeing Xu Hongling's shocked expression, Xu Yinglong said lightly: "You heard it right, it's human bones." Although all things do not float in this dark water, there are no human bones that are unsinkable, so as long as there are human bones, the river can be crossed. ”

"Where are we going to find human bones in this hurry?"

Suddenly, Xu Hongling looked at Xu Yinglong vigilantly, and said nervously: "You won't be"

Seeing this girl looking at him with a wary face, Xu Yinglong shook his head speechlessly and said, "Where do you want to go, even if it is not this river, I will not fight your idea, you can think of it!" ”

"Who knows, this society is so chaotic now! Besides, one of the things my mother often said to me when she was alive was that you can't have the heart to harm others, and you can't have the heart to prevent people! Xu Hongling said with a blushing face.

Xu Yinglong didn't care, Xu Hongling was right, in this impetuous society, you can't have the heart of harming people, but not only can you not have the heart of letting people go, but you also have to pay special attention to it. Xu Hongling is a girl, and her heart must be heavier to guard against others, so her reaction Xu Yinglong can also understand.

Immediately, Xu Yinglong said: "Don't worry, I, Xu Yinglong, am also a character, and I will never attack you as a weak woman." Besides, this immortal treasure was also told to me by you, how can I take revenge! Also, if I really had that plan, would I still tell you? ”

Xu Hongling thought about it carefully, what Xu Yinglong said did have a certain amount of truth, if he was really harmful, he would definitely not say this to her, and immediately returned to his original look.

"And how are you going to cross the river?" Xu Hongling asked again.

Xu Yinglong thought for a while and replied: "Since you were able to reach the other side of the river last time, it means that this river is definitely not a Jedi, we can walk along the river and have a look, maybe there will be some gains!" ”

Suddenly, Xu Hongling pointed to the ground and said, "Look! ”

Xu Yinglong fixed his eyes and found that there was a shallow footprint on the ground, which he really couldn't see if he didn't look carefully!

"Footprints?" Xu Yinglong asked with a frown.

"Here are my footprints!" Xu Hongling said a little embarrassed.

"Yours?" Xu Yinglong's eyes lit up and asked.

"Well, it's mine, I remember these shoes!" Xu Hongling said.

"Okay, then let's follow the footprints you walked and see how you crossed the river last time!" Xu Yinglong said in a deep voice. (To be continued......)
