Chen Xun stretched out his hand and stuck to the stone wall, and there was indeed a trace of warmth leaking out of the stone wall.

The red sun grass likes to grow in the land of yang fire, and usually does not grow in the depths of the cave, it is this stone wall that provides the growth environment for the red sun grass.

At this time, the remnant snow outside the mountain has not disappeared, and the valley where the lonely cliff stone pillar is located is in the spring and grows colorful flowers and plants.

With such thoughts, Chen Xun and Qianlan retreated to the entrance of the cave, and then walked in step by step, carefully measuring the distance and direction, and walked to the end to confirm the position of the bottom of the cave and the lonely cliff stone pillar, and the deviation between the front and back was only 500 meters.

The bottom of the cave is very open, thirty or fifty meters deep from top to bottom, left and right, and there are almost 1,000 red sun grasses between the growing stone gaps.

Xuegong controls the supply of pills in the western mountains of Tushan and even the entire Canglan Wasteland, and there are almost 2,000 Chiyang grasses gathered from the hands of tribes, scattered cultivators and sectarian forces every year, but most of them have a growth period of less than 100 years.

There must be a Chiyang grass that has grown for thousands of years and has pure medicinal properties, which is worth a thousand gold in Canglan.

The Nine Turns Golden Pill is made with a thousand-year-old spirit grass or a Hundred Years Spirit Grass, although it is called the Nine-Turn Golden Pill, but it is not a concept at all.

The boiling current of medicinal power formed by the former to impact the mysteries may be several times or even ten times that of the latter, and it is naturally easier to break through the flesh barrier and enter the realm of returning to the womb.

Chen Xun looked at the red sun grass in this hole, the roots grew dark purple, and he didn't know how many thousands of years had grown in this cave.

All the herbs that can be used for alchemy will turn into aura when they are put down in the Void Yuan Bead, but even if Chen Xun takes out the Red Black Knife and other things and carries them on his body, the space that can be freed up by the small Qiankun bag is extremely limited.

Two or three hundred Chiyang Grass filled the small Qiankun bag, and seeing that most of the Chiyang Grass could not be taken away, Chen Xun also had a headache: if he didn't take it at this time, most of these Chiyang Grasses would become the bag of the Xuanhan Sect in the future.

Chen Xun plucked two red sun grass plants and threw them into the Void Yuan Bead, the stems and leaves quickly melted away, and merged with the aura in the bead, but seven or eight crimson grass seeds, which were several times smaller than corn, fell quietly in the Void Yuan Bead.

Grass seeds can't be alchemy, nor can they refine magic weapons, but in the future, if you find a place with rich aura, you can plant and grow a large area of new red sun grass.

Chen Xun thought of this, so he specially pulled out the red sun grass that grew grass seeds on the stone wall and threw it into the Void Yuan Pearl.

After tossing for a long time, Chen Xun pointed to a stone wall that was vacant, and said to Qianlan: "You break this stone wall, let's see what is hidden behind it, and there is Xuanyang Qi leaking out." ”

Chen Xun can also smash the stone wall with a red black knife, but the movement is also large, and it is easy to alarm the whistle wolves roaming in the valley above.

Qianlan pulled out the Lingyin Sword, and the sword qi flickered, cutting into the stone wall.

The dark cyan hard stone wall, like soft tofu, was silently cut down by the sword qi piece by piece.

Qianlan was so tired that she was out of breath, so Chen Xun handed over a red sun grass.

Swallowing Chiyang Grass directly can only refine two-three tenths of the medicinal power, which is very wasteful, but compared to the pill on Chen Xun's body, so much Chiyang Grass can't be put into a small Qiankun bag and taken away, so it is wasteful.

Chen Xun also chewed two Chiyang grasses without incident, and introduced the medicinal power of Xuanyang into the hundred bones for cultivation.

After a long day's work, the Qianlan Imperial Envoy Lingyin Sword broke the stone wall to a depth of 100 meters, and a faint red light had already penetrated from the depths of the stone wall.

"Leave the rest to me to try......" kept asking Qianlan to be a coolie, Chen Xun was embarrassed, took out the frost knife from the void yuan bead, and released the frost knife to break through the stone wall.

As soon as the knife cut into the stone wall, there was a spiritual light shining through the stone wall.

Chen Xun was also caught off guard, and subconsciously, he only had time to put the frost knife horizontally in front of him, wanting to block the spiritual light that hit his chest, and he didn't need to think about having time to use the shadow splitting technique and cloud escape technique to dodge.

An indescribable huge force hit the Frost Knife, Chen Xunhu's mouth was immediately shattered, and the Frost Knife took off his hand and hit his chest again, and his whole person was knocked into the air.

Before Qianlan could react, Chen Xun was slammed into the other side of the cave.

Chen Xun fell heavily to the ground, and countless shattered and collapsed rocks pressed on his body again, and the entire cave was almost knocked down.

Chen Xun felt that the skeleton of the whole person had been dismantled, and he was pressed under the rocks, and he couldn't even use a little strength, and his intuitive organs were also torn apart by Juli, and his mouth was full of blood.

Qianlan picked up Chen Xun from the pile of rocks in a panic, took out the pill and gave it to him.

After a long time, Chen Xun eased up a little, but saw that the Frost Knife was broken and scattered on the ground, if it weren't for the Frost Knife to buffer it, I am afraid that only the soul sea transformed by the blood of the six-armed troll could save his life again.

Chen Xun struggled to climb over and peeled the stone wall open, only to see that there was a smooth and illuminating copper wall inside.

There was a faint flow of red light on the surface of the copper wall, and the spiritual light was released from this copper wall just now.

"What is this?" Qianlan was dumbfounded, the copper wall was dark red, and there was a spiritual light, obviously not made of ordinary copper and iron, but red refined copper that could be used to refine talismans.

The hole they broke was only one or two meters in size, and if this copper wall was connected to the lonely cliff stone pillar above the valley, how much red copper would it take to cast such a huge copper wall?

"The ancestor of the black python recorded that there is a secret cave stone hall hidden under the stone pillar of the lonely cliff, grandma's, I didn't expect it to be a copper hall raised by red refined copper!" Chen Xun spat out a mouthful of blood.

Chen Xun's mind was spinning rapidly, thinking to himself, if the secret hall from the lonely cliff stone pillar down was all cast of red refined copper, wouldn't there be hundreds of millions of catties of red refined copper?

He and Aoki Dao artificially refined the Gathering Spirit Fuyuan Array, and asked Zhao Tu to secretly buy five hundred catties of red essence copper, which cost thousands of runes, if he dug out this copper hall and kept it for himself, the entire Canglan Academy Palace would not be as rich as him.

It is no wonder that Xuan Hanzong and Qingyangzi want to plan for a hundred years and dig such a big pit for the Su family.

Not to mention the treasures in the secret hall, it is this red copper hall, which is worthy of the Xuanhan Sect and Qingyangzi.

Only when the Su family is crippled, and the Su family is completely unable to stretch out their hands to the north of the Python Tooth Ridge, can they monopolize the Jade Pillar Peak, and then slowly dig this red copper hall out of the ground.

Chen Xun took out the red black knife and tried to cut the copper wall again.

Qianlan hurriedly pulled him down: "Secret halls usually have extremely powerful prohibitions, you were really lucky just now......"

"I tapped hard this time. Chen Xun said with a relaxed face, the one just now almost shattered his body, but it was still far from the electric snake thunder light released by the fierce beast.

Chen Xun slashed it with a knife, and saw the red light flowing on the copper wall coming alive like water waves, and a spiritual light bounced.

Chen Xun's force was lighter this time, and the huge force released by the spiritual light only forced him back more than ten steps.

"Yes, the ban of the Secret Temple is based on the tenfold rebound of the added force, fortunately, I didn't use all my strength just now, otherwise I would have been shocked to death by the rebound, and I was really wronged. Chen Xun smiled bitterly.

Qianlan was also surprised by the strength of Chen Xun's body, Chen Xun just released the Frost Knife to break through the stone wall, although he didn't use enough strength, but the tenfold rebound force was also extremely powerful.

In other words, even if she had a bloodline aura and a body, most of them would be beaten to the point of being shattered.

"What do we do next?" asked Qianlan.

"Next, let's dig a hole up," Chen Xun said with a smile, "That divine wolf is very clever, but I never thought that we could dig a secret passage connecting the valley, right?"

The beasts forced everyone in the school palace to retreat into the valley, hoping to use the fierce beast trapped by the lonely cliff stone pillar to kill the people in the school palace.

If they can dig out a secret passage connecting the valley, the exit of this secret passage is more than twenty miles away, although it is not enough for everyone in the school palace to escape from the Jade Pillar Peak quietly, but as long as Su Lingyin, Su Fanglong, Su Qingfeng and other strong people can sneak behind the wolves, they may even attack and kill the divine wolf by accident.

Thinking of the mortal situation, they were asked to find a glimmer of life, Qianlan was also excited, and took a few steps back, and the Imperial Envoy Lingyin Sword began to cut the stone wall above.

They were about four or five hundred meters below the valley at this time, and if they were all such hard stone walls, they would have enough red sun grass to replenish the consumption, and they would be able to dig through it in about two days.

Seeing that Qianlan was energetic to dig the secret passage, Chen Xun didn't stop her, but he knew that Qingyangzi was the big trouble.

If Qingyangzi is not solved, even if they dig out the secret path, they will not be able to solve the current dilemma.

It is possible that Qingyangzi's injuries are not as severe as they appear on the surface, and it is also possible that he has hidden holy medicine, and his cultivation can quickly recover to the Tianyuan realm.

And Qingyangzi, as the Supreme Elder of the School Palace, will not be small in the power he has secretly cultivated.

Except for the Ghost Xi Department, no one knew how many people in the trapped School Palace and Canglan City were descendants who betrayed the Su family with Qingyangzi.

Chen Xun was swallowing Chiyang medicine to heal his wounds, and while thinking wildly, his soul suddenly palpitated, and he heard a small strange sound coming from outside the cave.

Qianlan quickly sensed the abnormality, walked up to Chen Xun's side, and asked, "What's the matter?"

Chen Xun secretly complained, it must have been because he was shocked by the spiritual light just now, and the cave shook the mountain, alarming the wild beasts in the mountain.

He and Qianlan flew to the entrance of the cave, and when they reached the middle section, they saw more than a dozen green wolves in front of them searching inside.

Seeing that Qianlan was about to kill with the Lingyin Sword in her hand, Chen Xun hurriedly pulled her back, brandished the red black knife, and slashed towards the stone wall.

They exposed their hiding and killed these dozen or so green wolves, which would soon attract even more powerful beasts.

Only by blocking these dozen or so green wolves outside can it be possible to delay time.

Back at the bottom of the cave, Chen Xun asked Qianlan to continue cutting the stone wall upwards, and he sacrificed the Soul Chasing Seal.

He didn't know if the Red Essence Copper Wall could cover his spiritual sense, but he had to try it anyway.

However, as soon as he extended his spiritual consciousness into the bronze wall through the soul chasing seal, a brilliant divine thought came out of the copper wall, and instead extended along his spiritual sense.

Without waiting for Chen Xun to react at all, the extension of that divine thought and the soul chasing seal turned into an incomparably pure divine power, blasting the soul chasing seal into pieces.

Seeing the cyan jade powder sprinkled from his hand, Chen Xun was shocked for a while.

He had heard Aoki Daoren say that when the Divine Soul was cultivated to a strong enough level, the pure Spiritual Sense Divine Thoughts could ignite the wick, but he didn't expect that this Divine Thoughts would hit and shatter the Soul Chasing Seal.

What kind of realm is this?

Watching the soul chasing seal turn into jade powder, Chen Xun's heart was even more bitter.

Zongya's blood dripped and attached the breath of the divine soul to the soul chasing seal, there was a soul chasing seal, when Zongya broke through, Chen Xun could know their location in time and rush over to respond.

Now that the Soul Chasing Seal has been destroyed, this mountain is all over the wilderness, how can he go to answer Zongya and them to break through?
