The only way

Chapter 916: Heavenly Crystal

After choosing a place to stay, Lingchu did not stop and took Qingkong and Qianyi Zhenren to the border between the two states.

During this period, the spiritual consciousness unscrupulously covered the entire Qingquan Mountains.

The low-level monsters and beasts without intelligence in the Qingquan Mountains felt as if a mountain was pressing down on them for a moment, and they lay whimpering on the ground.

Although those middle and high-level monsters also felt a chill on their backs and lowered their heads tremblingly, there were still some reckless monsters that raised their heads and roared, as if they wanted to relieve their inner fear in this way.

Ling Chu didn't care, but he used his spiritual sense to carefully explore the Qingquan Mountains, especially several streams and deep pools.

After some investigation, Lingchu already had a clear understanding of the monsters and terrain in Qingquan Mountains.

I don’t know if it’s because of the battle between humans and demons here, but in a place like Qingquan Mountains where spiritual energy is sufficient, and it’s quiet and secluded, there aren’t many monsters.

Most of these few monsters were hiding in caves. The few golden elixir monsters even occupied different hilltops, which were at a considerable distance from each other. It seemed that they did not interfere with each other.

Ling Chu also found no trace of the legendary clear spring.

but……

Ling Chu glanced at the ground vaguely, then smiled lightly.

They also learned from Qian Yi Zhenren that the monsters in the Qingquan Mountains have been very well behaved during this period, and have not interfered with the cultivators like them.

From this point of view, Ling Chu can basically be sure that there must be a being in the Qingquan Mountains who has reached the Great Perfection of the Golden Core or even the Nascent Soul stage and is in charge of the mountains, and his attitude towards the human race is at least friendly.

I just don't know if the one who rules the mountain is the Qingquan Fairy who is praised endlessly by the mortals living down the mountain.

"The mountains and rivers have spirits. As long as they are not hostile to us humans, we don't need to bother them."

Ling Chu's voice sounded faintly, echoing faintly among the mountains, as if he was talking to the mountains and rivers, or as if he was talking to Qianyi Zhenren beside him.

Qianyi Zhenren nodded thoughtfully, followed Lingchu's previous line of sight and looked at the ground, then he suddenly laughed, "Zhenjun is right."

They thoroughly investigated the mountains, but the Qingquan Mountains were not only above the ground, but also underground.

Speaking of hidden water, there is none more hidden than groundwater.

The Qingquan Immortal is most likely under the mountains.

What Ling Chu had just said was not only addressed to Master Qianyi, but also to all the demons in this entire mountain range.

It would be good if everyone keeps to themselves, and it would be best if we continue to maintain this way.

The whole mountain was silent, with only the faint sound of the wind.

True Man Qianyi frowned slightly, and a sharp gleam flashed across his eyes as he flew in the air. His roar, which contained a hint of oppression, echoed with the sound of the wind, and resounded over the mountain range.

Ling Chu, on the other hand, did not seem angry about being ignored. He just glanced at the ground and touched the angry sky.

"Let's go and see the borderland."

The so-called border area refers to the place where each state erected boundary markers when the five states were demarcated.

The boundary marker shows the place where the two states meet.

The border between Yunzhou and Jiumingzhou is very long, so there is naturally more than one boundary marker.

There is one in the Qingquan Mountains. The boundary marker is about ten feet tall, dark blue in color, with cinnabar filling it, and engraved with the name of this place and the boundary between the two states.

There is also a simple topographic map below, with mountains outlined in a few strokes and the border line outlined in red.

This is the image of the Qingquan Mountains and the specific boundary line drawn.

Along the border line, many cultivators are patrolling in spirit boats at this moment, to prevent the demons from Yunzhou from entering Jiumingzhou again, and to prevent the demons that have not yet been cleared out of Jiumingzhou from escaping.

When Lingchu and Qianyi Zhenren arrived, these spirit boats did not disrupt their patrol routes, and no cultivator left their post without permission.

"How many array cards have been deployed by the Yanzhen Sect?"

Ling Chu's spiritual sense spread to the border and was able to vaguely sense some fluctuations in the formation, but they were not strong and not complete.

"The formation cards of the Yanzhen Sect have not been fully produced yet, and the ones sent can only be used to set up less than half of the borders," said Qianyi Zhenren, with a distressed look on his face, a little annoyed with the Yanzhen Sect, "It's a pity that the Yanzhen Sect is unwilling to hand over the Tianjingbi Mine, and is unwilling to hand over the formation pattern secrets."

Ordinary formations are bounded by a certain range, wrapping up the area to form a complete encirclement. At the same time, all the formation flags are controlled by the formation plate. Once some of the formation flags are damaged, the formation will be damaged or even fail.

However, in recent years, the Yanzhen Sect has developed a new formation, using the Heavenly Crystal Wall to make the formation plates, which carry the formation patterns. As long as spirit stones are inlaid on each formation plate, a crystal wall can be formed after being activated.

6◇9◇Book◇Bar

This crystal wall is over a hundred feet high and invisible to the naked eye. Anyone who wants to pass through it will be blocked. If one tries to break the crystal wall with great force, it will form invisible waves that alarm all directions.

The most amazing thing is that as long as the same array cards are buried within a certain range, the crystal walls formed by the two array cards can merge with each other to form a larger crystal wall.

If the crystal disk is made with the same lineage of Tianjingbi marrow, all the Tianjingbi formation cards in the nearby range will be displayed on it.

As long as someone triggers the crystal wall, the Tianjingbi disk will sound an alarm.

It can be said that such formation cards and formation plates were born for times like this.

However, Heavenly Crystal Bi is rare, and the largest Heavenly Crystal Bi vein known within the Five States is in the hands of the Yanzhen Sect.

Only the cultivators of Yanzhen Sect know how to use the Heavenly Crystal Bi to make formation plates.

In the past, when the world was at peace, the monopoly of Yanzhen Sect was not a big deal. However, under the special circumstances now, the five major immortal sects wanted Yanzhen Sect to give up the Tianjing Bi vein and production method.

Of course, it is not a robbery. The Tianjing Bi vein is only temporarily handed over to the five major immortal sects for mining, and the used Tianjing Bi is paid for in spirit stones according to the market price.

The production method is also traded by each sect using spiritual stones or treasures.

But the Yanzhen Sect did not agree, or rather, did not agree completely.

Because the collection of all things in the world requires special techniques, the same is true for mining. The method of collecting Tianjingbi is one of the methods of Yanzhen Sect, but the five major immortal sects are not completely unaware of it.

The Yanzhen Sect was unable to refute this point, and finally had to agree with the five major immortal sects to send people to mine the Tianjing Bi vein together.

However, regarding the production of the Tianjingbi formation board, the Yanzhen Sect has never given in, because it is not just a matter of formation patterns, but also involves the secret method of Yanzhen Sect's cultivation, which no sect is willing to hand over.

Therefore, the production of formation plates slowed down, and most borders still required monks to patrol day and night.

Occasionally, some surprise attacks from the demons would capture lone monks.

Therefore, from time to time some monks would either sacrifice themselves or be captured by the demons.

Naturally, there were also cultivators from the Three Pure Ones Taoist sect who suffered. As an elder of the Three Pure Ones Taoist sect, Zhenren Qianyi always felt aggrieved and took his anger out on the Yanzhen Sect.
