Chen Xun reached out to the stone wall, and there was indeed a hint of warmth coming out of the stone wall.

The place where the red-yang grass likes to produce yang fire does not usually grow deep in the cave. This stone wall should provide the growth environment for the red-yang grass.

At this time, the remaining snow outside the mountain has not yet disappeared, and the valley where the lonely cliff is located is full of spring and colorful flowers and plants grow. When I see this stone wall again, there is also a warm current of sun fire. Chen Xun suspected that the place they are in is probably right below the valley.

With this idea, Chen Xun and Qianlan retreated to the entrance of the cave, then walked step by step, carefully measuring the distance and direction, and walked to the end to confirm that the direction at the bottom of the cave and the cliff pillars were located, with a deviation of no more than 500 meters in front and back.

The bottom of the cave is very wide, thirty or fifty meters deep up, and there are almost nearly a thousand red sun grasses between the growth stone gaps.

The Academy controls the supply of elixirs in Tushanxi Ridge and even the entire Canglan Wasteland. There are almost two thousand red sun grasses gathered from tribes, casual cultivators and sectarian forces every year, but the growth period is mostly less than a hundred years.

There must be a red sun grass that has grown for thousands of years and is purely medicinal, which is worth a thousand gold in Canglan.

The Nine-Turning Golden Elixir is refined with Thousand-Year Spiritual Grass or Breeze Spiritual Grass. Although they are all called Nine-Turning Golden Elixir, they are not the same concept at all.

The boiling flow of medicine that impacts the mysterious orifices by the former may be several times or even ten times that of the latter. Taking it will naturally make it easier to break the flesh barrier and enter the fetal state.

Chen Xun looked at the cave full of red sun grass, and his roots grew into dark purple. He didn't know that it had grown in this cave for thousands of years.

All the herbs that can be used to refine alchemy will be turned into spiritual energy when put down the Void Yuan Bead. However, even if Chen Xun took out the Red Crown Sword and carried it on his body, the space that the Small Qiankun Bag could free was extremely limited.

Two or three hundred red-yang grass filled the small Qiankun bag. Seeing that most of the red-yang grass could not be taken away, Chen Xun also had a headache: if you don’t take it at this time, these red-yang grass will most likely become the items in the Xuanhan Sect’s pocket in the future.

Chen Xun pulled out two red sun grasses and threw them into the Xu Yuan Bead. The stems and leaves were quickly melted and merged with the spiritual energy in the beads; however, seven or eight red grass seeds, several times smaller than corn, fell quietly into the Xu Yuan Beads.

Grass seeds cannot be refined alchemy or magic weapons, but in the future, you can plant large areas of new red sun grass that grow.

When Chen Xun thought of this, he pulled out the red sun grass that had grass seeds on the stone wall and threw it into the Xu Yuan Bead.

After struggling for a long time, Chen Xun pointed to the empty stone wall and said to Qianlan: "You break through this stone wall and let's see what is hidden behind it. There is the Xuanyang energy coming out."

Chen Xun could also smash the stone wall with a red black knife, but it was also very disturbing, which could easily alarm the whistle wolf wandering in the valley above.

Qianlan pulled out the Lingyin sword, and the sword energy flashed and cut into the stone wall.

The dark blue hard stone wall was silently cut off by the sword energy piece by piece like soft tofu.

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

Swallowing the Chiyang grass directly can only refine two or three out of ten medicine power, which is a waste. However, compared with the elixirs on Chen Xun, so many Chiyang grass cannot be taken away in the small Qiankun bag, so it is wasteful.

Chen Xun chewed two red sun grasses without any trouble and introduced the Xuanyang medicinal power into the bones for cultivation.

After half a day, Qianlan's imperial envoy Lingyin Sword broke the stone wall a hundred meters deep, and a faint red light had already emerged from the depths of the stone wall.

"Leave the rest to me to try..." Chen Xun was embarrassed to take out the Frost Sword from the Xu Yuanzhu and release the Frost Sword light to break the stone wall.

As soon as the sword light cut into the stone wall, a light of inspiration came out of the stone wall.

Chen Xun was also caught off guard. Subconsciously, he had only time to plaster the Han Frost Sword in front of him, trying to block the light that hit his chest, and he didn't have to have time to use the Shadow Split Technique and the Cloud Escape Technique to avoid it.

An unspeakable powerful force hit the Hanfrost Sword. Chen Xun's mouth was immediately shattered. Hanfrost Sword took off his hand and hit his chest again, and he was knocked to fly.

Before Qianlan could react, Chen Xun was hit hard on the other end of the cave.

Chen Xun fell heavily to the ground, and countless rocks that were broken and collapsed were pressed on him, and the entire cave was almost collapsed.

Chen Xun felt that his whole body had been dismantled and was pressed under the rocks and could not even exert any strength. His intuition also made the viscera look so hard that he could see the giant force and vomited blood.

Qianlan panicked Chen Xun from the pile of rocks and took out the pills for him to take.

After a long time, Chen Xun recovered a little, but saw the Han Frost Sword breaking into several pieces scattered on the ground. If it weren't for the Han Frost Sword cushion, he would probably have been able to save his life by the sea of ​​soul transformed by the blood of the six-armed trolls.

Chen Xun struggled to climb over and pulled open the stone wall, and saw that there was an extremely smooth and shiny wall inside.

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

"What is this?" Qianlan was stunned. The copper wall was dark red and there was a gathering of inspiration. It was obviously not made of ordinary copper and iron, but red essence copper that could be refined into talismans.

The hole they broke was only one or two meters in size. If this copper wall was connected to the lonely cliff pillars above the valley, how much red fine copper would it take to make such a huge copper wall?

"The ancestor of the black python records that there is a secret cave stone hall hidden under the stone pillar of the lonely cliff. Grandma, but I didn't expect it to be a copper hall made by Chijing Tong!" Chen Xun spitted blood.

Chen Xun's mind was spinning quickly, thinking, if the secret hall from the cliff pillar was cast from the red essence copper, wouldn't it have hundreds of millions of kilograms of red essence copper?

In order to refine the Spirit-gathering Yuan formation, he and Zhao Tu secretly bought 500 kilograms of red essence copper, which consumed thousands of talismans. If the bronze hall was dug out and taken for himself, the entire Canglan Academy would not be as rich as him.

No wonder Xuanhan Sect and Qingyangzi have to plan for a hundred years to dig such a big hole for the Su family.

Not to mention the treasures in the secret hall, even this Red Copper Hall is worthy of Xuanhan Sect and Qingyangzi's efforts.

Only by destroying the Su family and completely unable to reach their hands to the north of Python Yaling could they have the ability to monopolize the Yuzhu Peak and slowly dig out the Red Copper Hall from the ground.

Chen Xun took out the Red Crow Sword and tried to cut the wall again.

Qianlan hurriedly pulled him back: "The secret hall usually has extremely powerful bans, you were really lucky just now..."

"I'll use my strength this time." Chen Xun said with a relaxed look on his face. The thunder that had almost smashed his body just now, but it was still far worse than the electric snake lightning released by the ferocious beast.

Chen Xun slashed down with a knife, and saw the red light flowing on the copper wall appearing like water waves, and a bullet of inspiration came.

Chen Xun used lighter this time, and the huge force released by the aura only forced him back a dozen steps away.

"Yes, the secret palace ban rebounded ten times based on the added strength. Fortunately, I didn't use all my strength just now, otherwise I would have been shocked to death by the rebound, which would be really unfair." Chen Xun said with a wry smile.

Qianlan was also surprised at the strength of Chen Xun's body. Chen Xun just released the Frost Sword Light to break through the stone wall. Although he did not use enough strength, the ten-fold rebounding force was extremely powerful.

If she had bloodline and spiritual light to change her body, she would probably have been beaten to death.

"What should we do next?" Qianlan asked.

"Next, let's dig up the hole," Chen Xun smiled, "that divine wolf is extremely wise, but he never thought that we could dig out a secret passage connecting the valley, right?"

A group of beasts forced everyone in the Academy to retreat into the valley, hoping to use the ferocious beast trapped by the stone pillars of the lonely cliff to kill everyone in the Academy.

If they could dig out a secret path connecting the valley, the exit of this secret path was more than twenty miles away, although it was not enough for the people in the Academy to escape from Yuzhu Peak quietly, as long as Su Lingyin, Su Fanglong, Su Qingfeng and other strong people could sneak behind the wolf pack, they might even attack the divine wolf by accident.

Thinking of the situation of death, Qianlan actually asked them to find a glimmer of hope. He couldn't be excited. He took a few steps back and the Imperial Spirit Sword began to cut the stone wall above.

At this time, they were about four or five hundred meters below the valley. If they were all such hard stone walls, they would have enough Red Sun Grass to replenish their consumption and would be able to dig through them in about two days.

Seeing Qianlan digging the secret path with great enthusiasm, Chen Xun did not 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.

Qing Yangzi's injury may not be as serious as it seems on the surface; it may also contain holy medicines, and his cultivation can quickly recover to the Tianyuan Realm.

As the Supreme Elder of the Academy, Qingyangzi will not be less powerful in secret.

Except for the Guixi tribe, no one knew the trapped people in the academy and Canglan City, and how many people were betrayed the Su family's direct descendants with Qingyangzi.

While swallowing the red sun medicine to heal his wounds, Chen Xun was thinking about it all at once. Suddenly, his soul suddenly became terrified, and suddenly he heard a tiny sound outside the cave.

Qianlan soon noticed the abnormality, walked to Chen Xun and asked, "What happened?"

Chen Xun complained secretly, it must be that he was shocked by the recoil just now, and the cave was shaken by the earth, alarming the wild beasts in the mountains.

He and Qianlan quickly passed by the entrance of the cave. When they reached the middle, they saw more than a dozen green wolves in front of them searching inside.

Seeing Qianlan holding a spiritual sound sword in his hand, Chen Xun hurriedly pulled her, waved the Red Crow Sword, and slashed towards the stone wall. The rocks suddenly burst out like rain, and soon blocked the cave tightly.

They exposed their Xingzang and killed more than a dozen green wolves, which would soon attract more powerful wild beasts.

Only by blocking these dozens of green wolves outside can time be delayed.

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 the spiritual consciousness, but he had to try it.

However, as soon as he extended his spiritual consciousness into the copper wall through the soul-chasing seal, a powerful and unruly divine thought burst out from the copper wall, and instead extended along his spiritual consciousness.

Without waiting for Chen Xun to react, the divine thought extended and the soul-chasing seal turned into an extremely pure divine power, smashing the soul-chasing seal into pieces.

Seeing the green jade powder spread from his hands, Chen Xun was shocked.

He heard from Taoist Aoki Mu that the spiritual soul is cultivated strong enough, and the pure spiritual consciousness can ignite the wick. He did not expect that this divine thought would hit and would smash the soul-chasing seal into pieces.

What level of cultivation is this?

Seeing the soul-chasing seal turned into jade powder, Chen Xun felt even more bitter.

Zong Ya dripped blood to attach the soul aura to the Soul Chasing Seal. There was a Soul Chasing Seal. When Zong Ya and the others broke through, Chen Xun could know their location in time and rushed over to help.

Now that the Soul Chasing Seal has been destroyed, there are all over the mountains, how should he pick up Zong Ya and the others to break through?
