Xu Dong tried to use the perceptual skill to check the "Immeasurable Biography", when Hei Wuling gave him the perceptual skill on the ghost island of Haizi Lake, he once said that if he practiced this exercise well, he could open the "heavenly eye" in the deep layer of his human brain.

When he and Ansula practiced the "Sand City Order" in the Iron Cage Mountain, they couldn't decipher the runes on Ansula's body, so he first comprehended the perceptual skills, and then dissolved the layer of clouds that were 'covered' on the runes.

After going to Wuliang Island, he used his perception skills to unlock the contents of the ancestral temple murals, saw spirit stones and crystals in a white turbid gas and a translucent gas, and then opened two precious ore veins.

Later, he practiced "Demon Extermination" in the fourth secret room of the lotus "flower" and "hole", and he also used his perceptual skills to find the information of the four brothers and sisters of "'Spring' Jing", "Autumn Shuang", "Xia Fan" and "Winter Jane" in the words of "Lotus 'Flower' and 'Cave' Immortal Records".

Now, he wants to use his perceptual skills to unlock these three hundred and sixty paper symbols, not to mention unlocking all of them at once, even if he only unlocks some of them, he can also get a glimpse of some of them.

He condensed his mind and activated the perceptual exercises, but because he was busy with other affairs, he never 'took out' the effort to practice this exercise to the extreme, and he could only hold the mentality of giving it a try, hoping that the miraculous effect would be highlighted at this moment.

But he tried several times and failed, and the three hundred and sixty runes were still poked there, like nails on the board, and he sighed helplessly.

"The Water and Fire Dragon, a first-level demon, has already cultivated to the 'Pure Dragon Realm', and needs to use the 'Purple Sand Strength' to break it. ”

Xu Dong suddenly heard a strange voice, this voice was so old that people were worried to hear it, and he thought, if this was a human voice, then the person who made this sound was at least a few thousand years old.

"Who. He subconsciously asked, "Who's talking?" ”

He calmed down and listened, but no one answered, he thought that Uncle Long was nudging him, trying to 'make' a gimmick, deliberately pretending to speak in such a strange voice.

"Uncle Long, don't be so funny, just say anything you want, the apprentice can't stand your teasing like this. ”

Unexpectedly, Uncle Long didn't reply to his words, as soon as he 'touched' his heart, the ambergris embedded in his 'chest' did not have a burning sensation, proving that it was not Uncle Long who spoke.

Thinking about it again, this is in the ancestral temple mountain of the Mozha nation, which is full of ancient and strong barbaric atmosphere, and in this kind of secret realm, even some magic weapons are shielded, and it is impossible for Uncle Long, who has no body, to show up and speak.

Then, it must be their own auditory hallucinations, and in this special secret realm, auditory hallucinations or visual hallucinations are not impossible.

Xu Dong thought that he had hallucinated once, and after recovering from the surprise just now, he wanted to make one last effort, trying to use his perceptual skills to decipher the three hundred and sixty paper symbols.

Just as Xu Dong regrouped his mind, the strange voice sounded again, but this time it was not apprehensive to listen to it, it was low, rich, and a little depressing, but Xu Dong could hear it more clearly than the previous time.

"The demon dragon from the outer continent, the water and fire dragon, has been practicing for four thousand years, and has reached the 'Pure Dragon Realm', which is equivalent to the Yuanying Realm of human beings, and if you want to defeat it, you have to use the 'Gate' technique of 'Purple Sand Strength'. ”

Xu Dong caught the direction of the voice this time, it came from the stone hall outside, he hurriedly broke into the stone hall, and saw that Chief Mozha was still kneeling in front of the archer's skeleton.

"You still have no end, and you must have a degree of devotion to your ancestors, so that you don't become so pious, it's been a while, and you still kneel on the ground and can't get up. ”

Chief Moza ignored him, kneeling in front of the white bones as always, his lips squirming silently, Xu Dong understood the meaning even though he couldn't hear his voice, it was nothing more than a prayer that was too long to finish.

"Chief, I still have something to do, so be considerate of me, and let's get out quickly." ”

"Don't rush out yet, did you hear what I said? ”

Xu Dong was startled, it turned out that Chief Mozha could speak, but strangely it was not his own voice, this voice was so old that it seemed to have passed through a mysterious void.

"This is a demon dragon from the outer continent, named Water and Fire Dragon, who has been practicing for four thousand years, and now it has cultivated to the 'Pure Dragon Realm', which is equivalent to the Yuanying Realm of human beings, and it has to be cleaned up with 'Purple Sand Strength'. ”

The previous voice came from the mouth of Chief Moza, and it was evident that this was not what he was going to say, as if someone had gotten into his stomach and was only borrowing his mouth and tongue to speak.

Xu Dong analyzed the meaning of this again, obviously referring to the matter of the sea monster, the sea monster is called Water and Fire Dragon, and he has been practicing for 4,000 years, and if he wants to win the sea monster, he must practice a technique called "Zisha Jin".

He thought that this might be the god who had revealed him through Chief Moza, who had taken on Chief Moza's body while he was still in the woods, and that was why Chief Moza began to become Mumuddenden.

Who is this god, is it the ancestor of the Moza tribe, seeing that the Moza chief is so devout to their ancestor, could it be that the ancestral god is guiding the 'maze' to save the Wuliang Island from the demon dragon.

Xu Dong couldn't 'figure out' this, and he didn't want to 'figure it out', no matter which god pointed out, as long as it was a god's guidance, it would be helpful to him Xu Dong and to Wuliang Island.

"'Purple Sand Strength', where is the 'Purple Sand Strength', I don't seem to have this exercise in my hand. ”

"Wow. "Chief Moza took out something from his bosom and handed it to Xu Dong, this is a booklet made of animal skins, this animal skin booklet has completely become purple and brown, and at a glance you can see that it has existed for at least thousands of years.

Xu Dong looked at it, there was no text on the cover of this booklet, and there was a simple and simple diagram inside, without any text explanation, how could this prove that it was "Zisha Jin".

After Chief Moza gave the animal skin booklet to Xu Dong, he immediately regained his sanity and changed to a different person, not seeing anything abnormal, and suddenly changed back to his original appearance.

"Xianjun, let's go out of the ancestral temple. ”

"Chief Moza, what happened to you just now, do you know what you said and did? ”

Chief Moza didn't seem to know about the possession of the gods, and he was ignorant for a long time, "I, nothing, do I have anything?" ”

Xu Dongsuo took out the animal skin booklet and showed it to him, "This is what you just gave me, look at what this thing is, it looks like an exercise, but is this exercise 'Zisha Jin'." ”

Chief Moza was even more ignorant, "'Purple Sand Strength', what 'Purple Sand Strength', this animal skin scroll was passed down from the previous chief when I was the chief, I can't remember how many generations this thing has been passed on." ”

Xu Dong asked, "When the previous chief passed it on to you, did he say what kind of exercise it was and what role it played?" ”

Chief Moza said with great certainty, "He did not say anything, but only 'entrusted' me to keep this scroll of hides, saying that someone would naturally take it in the future, and his predecessor had told him so." ”

"Oh. ”

Xu Dong thought, this matter is really mysterious and mysterious, and can only be explained by the guidance of the gods, regardless of whether this animal skin scroll is "purple sand power" or not, he will practice according to the map first, maybe he can really use it to defeat those sea monsters.
