The formation laid out in the cold rain for more than ten days before is called the Dust Lock Yuan Array, which is a magical formation in their spiritual gate that is used to observe the surrounding earth qi, weather changes, and can also be adjusted to change the landform.

The core of this array is in a slightly sunken col on the east side of the Heavenly Burial Mountain, and there is no formation eye in itself, but she uses magic to manipulate the surrounding earth qi and plant vitality to form a chain vortex, once formed, she only needs to touch a wooden card that she left in the center of the invisible vortex buried in the ground and the vortex can resonate, and you can know the direction of all the animals and plants in the entire Heavenly Burial Mountain and the direction of the earth qi, if it is touched by the same door or a magician, it can also be controlled.

Of course, the premise of all this is that the person who gets the wooden card needs to have more than 100 skills, or be a magic practitioner with strong perception ability.

Xiao Sha and Chu Wenxin didn't need to control it at this time, they just needed to closely monitor this maple demon to prevent it from escaping under Feng Ling's hands, for intercepting such a monster whose cultivation was not as good as any of them, it was theoretically more than enough for them to be able to do it now, and what they were worried about was that this monster from the void would be different from Shenzhou.

……

In the dark, the two of them moved quickly, and when they returned to the Heavenly Burial Mountain from the periphery, their feet were volleyed, their bodies were suspended, and they flashed through the mountain like ghosts, without touching any branches and leaves, making a sound, and they were very cautious, and they came to the mountain col that Han Yu had said before.

Actually, it's not hard to find, because there are only three cols on the east side, and there is only one place that matches the characteristics of Cold Rain!

It is a col surrounded by mountains on three sides, with a large number of dense woods and weeds behind it, and the place is very small and can only accommodate five or six people. Xiao Sha and Chu Wenxin, who came quietly, rummaged a little on the ground with a little weeds, and found the sign that Han Yu said was used to sense the vitality of all things in the entire Heavenly Burial Mountain and the direction of the earth's air flow.

To be honest, this wooden plaque carved casually by Hanyu is indeed quite rough, it is a simple wooden plaque about the size of a palm, carved from ordinary wood in the mountains, and there are many small holes on it according to a certain law, except for those small holes that seem to be regular, and the surface is rough and ugly, not smooth at all.

But at the moment when he got the wooden card, Xiao Sha clearly felt that in his hand holding the wooden card, there seemed to be thousands of wisps of qi scurrying and swimming, and it felt as if what he was holding was not a wooden card but countless things with its own qi vitality.

The next moment, he suddenly woke up and integrated his spirit into it, and soon realized how huge and complex this qi machine was, and finally understood why Han Yu said that he could monitor the entire Heavenly Burial Mountain by relying on this wooden card alone.

……

……

Hanyu didn't lie!

At this moment, according to the countless qi machines floating in his palm, Xiao Sha quickly sensed the mystery according to the instructions of the cold rain before he came.

At this time, there were countless qi machines circulating on the back of his fingertips and hands on the wooden card in his hand, densely packed and warm, stranded little by little, endless and different.

It is dense and ubiquitous, like the waves of the sea, and the undulating atmosphere of the earth is circulating!

In the earth's qi, it is like an immovable rock, taking root somewhere, and there are thousands or even hundreds of millions of plants of all sizes in various places in the Heavenly Burial Mountain!

In it, the breath is slightly warm or cold, and there are all kinds of cold-blooded or hot-blooded animals in the mountains!

There are ubiquitous dots around these animals, each tree is a moving point, each animal is a swimming fish, and the different species of trees have different breaths and vitality in the faint swallowing, and the swallowing methods are also strange. Depending on the size and type of animals, the qi presented is also different, and even the death qi on the bones of the human beings devoured by the maple demon is different.

Although it is full of qi engines, countless such qi machines are gathered in this wooden plaque, and in his hands it actually presents a face hidden by nature under the surface.

It wasn't until this time that Xiao Sha discovered that there was such a mystery behind nature, and there was such a mystery between heaven and earth, which he didn't dare to imagine from the earth to here.

And in this kind of operation behind nature, he is also vaguely aware that if he describes himself in terms of mountains, rivers and rivers, then under such a qi machine, he may be able to have some understanding and speed up the speed of his true qi and the integration of heaven and earth!

However, he also knew that now was not the time to think about his own breakthrough, and when he thought of this, he decided to wait until he went back and let Hanyu help him get one like this, so he quickly collected his heart and began to monitor where those maple trees were.

……

There are countless qi engines on the wooden card, hundreds, thousands, thousands, even tens of millions, hundreds of millions, billions, billions, among which the large and small qi engines correspond to countless animals and plants in the mountains, ants have qi engines, trees have qi engines, and the ground and underground are everywhere, and the number is easy to make people who are not cultivated enough to be lost in it, and it is difficult to trace what they want.

However, this is not the case with the Maple Demon Pack!

The wooden plaque corresponds to the entire Heavenly Burial Mountain, and the circulation of the earth's qi also outlines the topography of the Heavenly Burial Mountain, so that Xiao Sha knows which animals and which plants are where, so that he will not be overwhelmed by so many qi engines.

The most important thing is...... Compared with the rest of the large and small qi vitality and the qi vitality of the maple demon group, it is as conspicuous as the sun in the darkness in the large ecological park of the Heavenly Burial Mountain.

Among all the qi inductions, the qi vitality induction located in the place where the Heavenly Burial Mountain Maple Demon is located is the strongest, and even because of the special nature of the Maple Tree Demon, Xiao Sha entered this state and felt that the entire Heavenly Burial Mountain Maple Demon Group was exuding a strong vitality to the extreme.

This vitality is almost so powerful that the vitality of all the animals and plants in half of the Heavenly Burial Mountain is not as strong as a maple tree, so many maple demon groups gathered together in the wooden card induction are as bright as mountain fires in the dark, the roots and stems that are buried in the ground and wriggling frantically absorbing the earth's qi, the pieces of maple leaves that are still absorbing the earth's qi even if they fall on the ground, and still have a lot of vitality, maybe the maple demon group is just one of the many trees in the mountain on the surface. But it is the most conspicuous existence in the qi machine inducted by the wooden brand.

Judging from their crazy behavior of devouring the earth's qi and robbing the surrounding trees of their nutrients, Xiao Sha has reason to believe that as long as they are given enough time, in two or three months at most, all the animals and plants within a hundred miles of the Heavenly Burial Mountain will be completely extinct and replaced by maple trees all over the mountain, and these maple tree demons who were melted by Feng Ling and fled here less than a month ago will inevitably reproduce in an astonishing number again.

As for the combat power described by Feng Ling, if it finally spreads within a radius of five hundred miles, unless it encounters a world-class supreme swordsman like Feng Ling, and the world's highest temperature and most powerful Fire Divine Skill True Qi, even if it encounters three or five top masters at the peak level of refining, it may not be able to rely on the huge number of maple trees to consume them alive.

……

……

"How?"

Seeing that he held the wooden card and closed his eyes for a long time without speaking, Chu Wenxin, who was hiding in the col with him, whispered: "Have you found the Qi of the Maple Demon, is this thing useful?" ”

"See for yourself"

Finally reined in his thoughts, Xiao Sha handed the wooden card to Chu Wenxin, seeing that he held the wooden card in his hand and showed a look of surprise, and gently patted him on the shoulder: "You take this wooden card to the highest place on the mountain, I will go and inform Feng Ling to go down, and then we will meet at the highest place to prevent the maple demon from escaping, although Han Yu said that this thing can only be used for three days at most after it leaves the ground, but it is enough!" ”

"Uh...... Good, good! ”

Chu Wenxin was shocked by the huge content of the wooden card in his hand at this moment, and he was a little absent-minded when he heard the promise.

Xiao Sha didn't say much, and immediately took up his light skills and quietly left the range of the Heavenly Burial Mountain, soaring into the sky into the clouds in the distance, and then returned from the clouds to where the three of them were before.

……

At this time, Feng Ling was still floating in the air below the clouds, looking down, holding a dark red dress full of spiritual blood, looking heroic, and the real air around him was already ready to go, and he took the initiative to enter the clouds before he came.

As soon as she came, Xiao Sha jokingly raised her hand and grabbed her waist; "I've found the core, everything in Heavenly Burial Mountain is under control, but you have to be careful, this thing is full of vitality"

"Just do your own thing, and I'll leave it to me."

Feng Ling pushed him away angrily: "Are you sure there won't be any fish that slip through the net?" ”

"The core of the spell left by the cold rain is very wonderful, there should be no problem with me and Lao Chu"

Xiao Sha, who was pushed away, smiled disappreliantly: "On the contrary, it's you, it knows you and is afraid of you, but there may not be new means during this time, it's better to be careful."

"There is no problem with the periphery, the rest ...... Just look at it."

Feng Ling nodded and said no more, and after saying a word, the whole person turned into a fiery red light and fell from the sky to the maple forest below, the blazing high temperature accompanied her true qi to burn a white smoke in the air, and the scorching high temperature made Xiao Sha happy, to be honest, he had never seen Feng Ling after his skill reached the peak of refining, and now with this expectation, he fell to the highest place of the Heavenly Burial Mountain with the same convergent aura as before.

It's all at the moment when the poor dagger sees it, and he doesn't care, it falls directly from the air, so conspicuous!

And on the highest peak of the Heavenly Burial Mountain, Chu Wenxin, who was one step ahead of him, had already arrived, and at this time, standing on the top of the mountain at a glance, holding a wooden card in his hand, his eyes were also staring at the maple forest falling from the fiery red light, waiting for the moment when the fire was shining!
