The following day, the "Spirit Servant Palace" returned to its former tranquility. , BEn, As the sect master of the "Spirit Servant Palace", although Wei Jingzhen has become a saint, and he is also the first Xuanyu saint since the Pangu Great God opened the world, he still doesn't dare to be careless, he just wants to comprehend the remaining heaven and earth origin as soon as possible, so that his formation power can go further, but unfortunately he has not been able to comprehend it.

"Here, I can no longer comprehend the origin of heaven and earth!" Wei Jingzhen knew that in this heaven and earth, not all origins were embodied in one place at the same time, and in different places, only the corresponding origin could be comprehended. For example, in a canyon, there may only be the source of prevention, the source of sleep, or other sources. In short, a place can only embody one or several of the origins of all heaven and earth, and it is absolutely impossible to embody all the origins of heaven and earth at the same time.

"It seems that if I want to comprehend the following several origins, I can only go to some dangerous and desperate domains and experience it for myself......" Wei Jingxin began to have a plan to travel far away. The further back the origin of heaven and earth, the more powerful it becomes, and if you want to comprehend the origin behind, you must go to the most dangerous place in heaven and earth, and understand the last mystery at the moment of life and death.

Although Wei Jingzhen's plan was unanimously opposed by all the elders, Wei Jingzhen still decided to leave Lingpu Mountain and go to a wider and more dangerous place. Wei Jingzhen has his own thoughts, this trip is not only to comprehend the origin of heaven and earth behind, but also to find the whereabouts of Yihai, not only to avenge the old man Yuanxu, but also to take the "Fengshen Stone" on Yihai's body.

Wei Jingzhen tried his best to persuade Feng'er, Naga and the others, and then went underground to discuss with the Emperor Yitian, and asked this strong old guy to help when the "Spirit Servant Palace" was in danger, and finally took Lulu and left the Lingpu Mountain Realm, and flew towards the worse and barren place in the northwest of the Demon Realm.

The two of them flew in the gray sky one after the other, blushing, and asked Wei in shock, "Sect Master, are you...... Why don't you take Miss Feng'er with you, but ...... Only with a purr?"

Wei Jingzhen didn't pay attention to Lulu's expression, just stared ahead, and replied calmly: "Lulu, I took you out this time in the hope that you can be exercised in a difficult situation." You are a heaven and earth spirit beast yourself, and your potential is huge, if you can develop all these potentials, I'm afraid that even I will not be your opponent in the future!" Wei Jingzhen was right, Lulu was a heaven-swallowing beast "Emperor Hong", an ancient spirit beast in the Chaos Period...... Perhaps, it would be more appropriate to say that it is a ferocious beast.

About the Sky Swallowing Beast, there is such a legend in the fairy world, when the chaos first opened, there was once an adult Sky Swallowing Beast entrenched in the chaos of the universe, so that the Pangu God who tried to open the world also suffered enough, and finally, it was the Pangu God who was able to surrender the Sky Swallowing Beast with the help of an artifact and open up this world.

Of course, legends are just legends after all, but the powerful strength of the Sky Devouring Beast Emperor Hong can also be seen from this.

What Wei Jingzhen needs most at this time is a powerful helper, although he has become a saint, but Wei Jingzhen knows that his strength is far from enough compared with the Demon Emperor and Ghost Emperor at the dominating level.

Lulu didn't know Wei Jingjing's true thoughts, and when she heard Wei Jingzhen praise herself, her face suddenly turned red, and her misty eyes didn't dare to easily touch Wei Jingjing's gaze, but she followed Wei Jingzhen step by step, flying slowly.

Since washing in the demon world "washing pool", Lulu once devoured the spirit beast of heaven and earth under the waterfall pool of Lingpu Mountain, not only faded away the ugly demon body, transformed into a graceful and graceful girl body, but also condensed a pair of bright eyes and good eyes, if placed in the human world, Lulu's current appearance can be said to be a country and a city, talent and national color. Now, when Lulu learned that her master went on a long trip and didn't take Miss Feng'er with her, but only picked herself, her heart couldn't help but be filled with strange sweetness, and even her heartbeat was a little faster than usual.

The two of them flew in the sky for two days, and gradually saw a barren barren mountain in the distance, one side of the barren mountain was as smooth as a mirror, as if it had been cut by someone by means of sword qi and other means, and there were three big characters on it: Milu Mountain.

"Mi Lu Mountain?" Wei was surprised and curious, and flew forward at a faster speed. Lulu was thinking about what was on her mind, when she noticed that Wei Jingzhen had sped up and followed closely behind.

The two landed on Milu Mountain and found that on the top of the mountain was a huge funnel-shaped depression, which was about ten zhang square at the widest point. At the bottom of the sunken mountaintop, there was a small pool of reddish liquid, which was bubbling outward, and it looked like a pot of boiling blood from a distance.

"These liquids ......" Wei was startled for a while, "These liquids are really blood!"

"It turns out that this is the pool of blood!" Wei Jingjing did not forget to tell Lulu behind him, "Lulu, be careful yourself, there may be danger here!"

Lulu nodded, but her heart didn't know what thoughts were turning, and her face turned even redder.

Wei was stunned by his divine sense covering the distance, confirming that there was no third person within a radius of thousands of miles, so he waved his hand and laid a wind formation in the space, firmly protecting Mi Lu Mountain all night. Since comprehending the twelfth origin, Wei Jing's formation has reached an unprecedented height, and even the teleportation of the Mixed Yuan Saint cannot calmly cross the formation space that he has arranged with his own hands.

With the formation set up, Wei Jingjing began to fly down towards the recess of the mountain, stopping next to the pool of liquid that was almost dry.

"This pool of blood seems to have dried up, judging from the height of the depression, it shouldn't have been like this before!" Wei opened his consciousness and tentatively poked towards the bottom of the blood pool, wanting to see what was the reason for this famous and dangerous place in the Demon Realm to become what it is now.

As soon as the stretched out divine sense touched the bottom of the blood pool, Wei's stunned face suddenly changed. He found that there was a hole the size of an arm at the bottom of the blood pool, and a large amount of gas was constantly escaping from the small hole, forming a large number of bubbles in the blood pool, constantly making a "gurgling" sound.

"Lulu, come here. Wei was stunned and summoned Lulu forward, and then took out a pagoda-like magic weapon from the storage ring, which was the best immortal weapon of the transportation class "Seven Treasures Linglong Pagoda".

Wei was stunned to sacrifice the Linglong Pagoda, so that the pagoda only stretched to the height of one floor, first let Lulu enter, and then he also entered the pagoda, reciting the mantra to make the "Seven Treasures Linglong Pagoda" thinner, and then the pagoda submerged to the bottom of the blood pool, against the small hole that constantly spewed a large amount of gas, and traced back along the back passage.

In the space inside the "Seven Treasures Exquisite Pagoda", Lu Lu raised his head with a flushed face, and asked Wei Wei curiously: "Sect Master, we are ...... now Where are you going? Is there something strange in this pool of blood?"

"Lulu, we're just going back to the source along the passage at the bottom of the blood pool, and I don't know where we'll end up going to. Wei shook his head, and then said what he had discovered, "Lulu, have you noticed it, what is constantly escaping from the bottom of that blood pool just now is a strange aura similar to the qi of the immortals, and the purity of this aura is several times stronger than the qi of the immortals!"

Wei was shocked to tell his discovery, and when he saw Lulu, he just nodded slightly, and couldn't help but feel a little bored at the moment, if Feng'er was here, he would definitely pester himself to ask, unlike Lulu who didn't even say a word. In fact, where did Wei Jingzhen know Lulu's thoughts, in Lulu's mind, he always only knew that he followed his master, no matter the difficulties and dangers, wherever he went, he didn't bother to care about it at all.

Under the control of Wei Jingjing, the "Seven Treasures Linglong Pagoda" carried the two of them and flew to the source along the deep passage. Wei was stunned and silently calculated the day, and found that this passage was very long, and he and Lulu had been flying for two months under the carrying of the pagoda, and they had not yet flown to the end.

"Why has it been so long?" Wei was stunned and became impatient, "I haven't flown to the end for two months, and now, I don't even know where I am!"

The two-month wait was boring and tedious, and if in normal times, Wei Jingzhen would either cultivate or immerse himself in the deduction of the way of arithmetic, he would not feel that time passed very slowly at all. It's just that now, I have exhausted the number of calculations and evolution, and I have reached the point where I can't calculate, I can't act, I want to cultivate, but I have become a Xuanyu Sage, and I have temporarily reached a bottleneck, and I can't cultivate at all...... It's not that Wei Jingzhen didn't want to chat with Lulu to relieve his boredom, but the problem is that Lulu is like suffering from a language barrier, and every time he says more than ten or twenty sentences by himself, Lulu only responds slowly with "um", "ah", and "oh", looking absent-minded.

Bored, Wei had to take out the "rules" and "moments", draw a perfect circle on the ground, and then use the two things in his hands to make an inscribed regular trilateral......

Half a year has passed, and the surroundings are still dark, Wei Jingzhen from time to time with his divine sense, and found that the aura around the "Seven Treasures Linglong Pagoda" has become denser and more pure, so he knows that it may not be far from the source of this strange aura.

On the ground, it has already been painted with all kinds of circles, and the inside of the circle is crisscrossed by Wei Jingzhen with "rules" and "moments" to depict many different shapes. Regular trilateral, regular quadrilateral, regular pentagonal......

As for Lulu, sometimes curiously watching Wei Jingzhen entertain himself on the ground, sometimes quietly cultivating cross-legged, in short, if Wei Jingzhen didn't talk to her, she wouldn't take the initiative to burst out half a word even if she was killed.

Another half a year had passed, and the "Seven Treasures Exquisite Pagoda" had meandered through the dark passage, and had not yet been able to fly out of the passage. At this time, Wei was no longer impatient, but entered another world.

"Strange, how did I make a regular eleven-sided shape in the first place?" Wei Jingzhen was already stumped by the problem of regular heptagons at this time, and couldn't help but speed up his previous practice, "First make a regular twenty-two sides, and then connect them in pairs to get a regular eleven-sided shape...... That's what I said to that old guy at Yitian...... The problem is that it is impossible to make a regular twenty-two square with only 'rules' and 'moments'! It seems that my previous method must not be rigorous enough!", and began to draw with a compass again.

Wei knew exactly what he was doing. Since the power of the formation is closely related to the pattern arranged, what I want to study now is how to make more origin formations more and more tend to a perfect circle when superimposed to form a new composite formation.

Wei Jingzhen knew that the circle was the most perfect and impeccable pattern in this heaven and earth, and even in the entire universe, if he could figure out the key to it, then the formation that would be displayed in the future might even make him feel afraid.

If the understanding and mastery of the laws of number derivation has endowed Wei Jingzhen with profound and extreme Yuan power, then the current study of the circle will undoubtedly make Wei Jingzhen go to a higher level in the way of formation.

Just when Wei Jingzhen was still immersed in the study of the regular heptagon, a violent light suddenly came from outside the "Seven Treasures Exquisite Pagoda......
