"There is actually such a formula, great, please teach it to me. I will immediately order these spirit insects to start collecting the Gangyin Sand."

Chen Yun was surprised and delighted when he heard the news, and immediately continued. Whether it was out of desire for Gangyinsha or yearning for powerful spells.

"Before that, I have to tell you that no matter how much Gangyinsha you obtain in the end, it must first satisfy my needs for refining the last puppet."

"It must not be wasted on other uses, and certainly not added to your magic weapon."

"If there is any leftover during the puppet refining process, then you can dispose of the rest as you wish. I will not interfere in any way."

Before imparting the magic formula to Chen Yun, Lord Dayan calmly put forward his own request.

"Forgive my foolish opinion, Senior, maybe you don't know that the treasure I use does not have to be mixed with Gangyin Sand, but has been tempered and refined by Refined Crystal."

"Compared with Gangyinsha, this type of material has better effects."

Chen Yun couldn't help but smile when he heard this.

"Refined crystal? You actually possess such a miraculous material. May I ask if there is any left? Even a tiny bit would be extremely precious and of great use to me."

Lord Dayan seemed to be stunned for a moment with surprise, but then he shouted out excitedly, his voice filled with extreme joy.

"To be honest, the treasure I use is a set of flying swords. Although the amount of refining crystals I obtained was not small, it was only enough to barely meet my needs, so I really couldn't leave any extra parts."

Chen Yun replied in a calm tone.

"Have they all been used up? What a pity!"

Lord Dayan instantly fell into deep disappointment, murmuring regretfully.

When Chen Yun heard this, he couldn't help but roll his eyes in his heart.

It is not a waste to use the refined crystals to cultivate one's own magic weapon.

However, at this moment he needed something from the other party, so he had to pretend to be ignorant and listen to the other party's complaints.

At this time, Chen Yun had already followed the two people in front of him deep into the cave for a distance, and intentionally or unintentionally kept a certain distance from them so as to avoid being noticed by them about his abnormal behavior.

Although the light in the cave was dim, the three of them were all cultivators with profound cultivation. They only needed to inject a little spiritual power into their eyes to see the general outline of the surrounding environment without any obstruction.

The size of the cave remains the same as at the entrance.

The two-colored stone walls still have a light yellow hue.

While moving forward, Chen Yun casually swung a flying sword and slashed the stone wall.

However, the color displayed is still the glittering silver color.

Chen Yun was slightly shocked, but he became more determined to obtain these mysterious mineral deposits.

As Chen Yun walked, he listened to the key points of insect repellent that were taught to him by Lord Dayan through his spiritual consciousness.

Although the formulas are composed of ancient characters, they are a bit difficult to understand.

But under the brief and careful guidance of Lord Dayan, Chen Yun, who was already quite knowledgeable about the art of expelling insects, quickly grasped the mystery of it and successfully achieved a mastery of it.

When the incantation was finally passed on, Lord Dayan's voice became silent again.

Chen Yun lowered his head and pondered over the formula, and after confirming that it was correct, he gently waved his hand, put the spirit beast bag on his waist into his sleeve, and disappeared without a trace.

Then, Chen Yun's pace did not change at all. However, from his sleeves, golden gold-eating insects flew out silently and rushed in the direction they came from.

The two people walking more than ten feet ahead did not notice Chen Yun's little movements at all.

About a quarter of an hour later, all the gold-eating bugs in the bag had been released.

Chen Yun clenched his fists and formed a magic seal, while a low incantation sounded in his mind.

And it was transmitted through spiritual consciousness to the large number of gold-eating insects that were floating in front of the stone wall at the entrance of the cave.

The golden cloud of insects suddenly burst into dazzling light, and then all the flying insects blurred for a moment and rushed towards the stone wall like a tide.

It actually penetrated directly into the stone wall without any hindrance and disappeared without a trace.

There did not seem to be any signs of damage on the surface of the stone wall.

Chen Yun sensed the scene before him through his spiritual sense, and then he calmly returned his mind to his body and gradually quickened his pace.

After walking for a while, they just turned a corner when the two people in front of them suddenly stopped. Chen Yun was startled and hurried forward to check the situation.

Suddenly, the view ahead opened up and the passage became extremely spacious in an instant.

In this wide passage, there are countless strange stalactite-like rocks distributed from top to bottom, emitting strands of silver-white light, making the entire passage as bright as day.

Although these strange silver lights in front of me are invisible, each ray of light is extremely clear and bright, as if it has a substantial form.

"This is the legendary Northern Light. Although you two Taoist friends may know something about it, I still need to emphasize it again."

"Under the cover of the Northern Lights, you must not use any spiritual power or magical tools at will except the Yin-Yang Ring."

"As long as the spiritual energy overflowing from our bodies is sensed and captured by the Northern Lights, the three of us will be in extreme danger."

Nanlong Hou stared at the silver light in front of him, took a deep breath, and pointed out seriously and solemnly.

Chen Yun remained silent and did not respond.

However, he waved his sleeves lightly and threw out a black ring, which spun several times before falling steadily back into his hand.

There is a brilliant light flashing on the ring!

When Chen Yun took out the Liang Yi Ring, Nan Long Hou and Lu Weiying immediately moved away and retreated to a distance of about ten feet behind Chen Yun with stern faces.

This indicates that the next action will be led by Chen Yun.

Chen Yun held up the ring, opened his mouth and spit out a cloud of green mist, covering the ring.

The black light flickered continuously, and all the green mist was absorbed by the ring. Then the ring made a sharp whistle, automatically flew to the top of Chen Yun's head, and hovered in the air without moving.

Chen Yun waved his arm expressionlessly, and a spell hit the ring.

The Yin-Yang Ring trembled slightly, and then began to contract and expand.

In a blink of an eye, the original ring had turned into a huge circular ring with a diameter of five or six feet.

"go"

Chen Yun stretched out a jade-white finger, pointed at the ring, and gave a soft command.

With a strange roar, a huge ring rushed out.

The looks of Nanlong Hou and Lu Weiying instantly turned serious.

I saw a huge ring rushing into the countless rays of light, and an incredible scene occurred. The straight rays of light were like a disturbed water surface, and fell into chaos the moment the ring broke in.

As the black light continued to flash, all the light would magically change direction once it touched the outer wall of the ring, and actually bypass the finger and go back along the original path.

It seems to be spiritual!
Seeing this scene, Chen Yun felt relieved. Nanlonghou and the other man also smiled.

However, Chen Yun was still curious about the power of the Arctic Yuan Light.

After a brief thought, he slapped the storage bag with one hand, and a fist-sized blue round bead appeared in his hand.

This is a high-level protective spiritual weapon obtained in the early years.

Chen Yun held the treasure in his hand and injected a little spiritual power into it.

Suddenly, a blue light curtain emerged and covered the surface of the bead.

Chen Yun flicked the ball with his backhand, and the ball turned into a blue light and rushed out.

This time, the blue light bead stepped into the Arctic Elemental Light field, and the lights seemed to see delicious food. After shaking violently, they quickly wrapped around it.

Rays of light as thin as hair penetrated every part of the blue bead, making the light shield seem like nothing.

A moment later, the round bead that was penetrated by numerous rays of light flashed several times, then exploded from the inside, turning into a ball of brilliant light that dissipated among the numerous rays of light.

Chen Yun's pupils shrank slightly, and the expressions of Nanlong Hou and the old man also turned gloomy.

Chen Yun's expression returned to normal in an instant.

He stretched out his hand and a huge ring flew back above his head, then fell quietly, covering the three of them.

Immediately afterwards, a black light shield appeared outside the ring, protecting Chen Yun and others.

"lets go!"

Chen Yun didn't say anything else, just gave clear and concise instructions, then walked forward, with the Liang Yi Ring following behind him.

Nanlong Hou and the old man surnamed Lu were inside the light shield and did not dare to be negligent at all, and followed closely behind carefully.

Although they had witnessed the powerful protective ability of the ring against the Arctic Light, they still did not dare to activate any protective measures or use any magic weapons before entering the Arctic Light.

Although Chen Yun seemed calm on the surface, he was actually a little worried inside.

However, when they actually stepped into the Arctic Elemental Light Realm and found that the light did bypass the black light shield and did not approach them, they finally put their minds at ease.

After a slight adjustment, Chen Yun's heart moved, and he turned to look at Nanlong Hou and the other man, and found that they also looked relaxed.

Chen Yun smiled slightly and urged the Liangyi Ring to move forward steadily.

……

On a cold land deep in the Demon Valley, quite close to the interior of the valley, there were many people wearing black robes.

A practitioner of the Ghost Spirit Sect wearing a black hat is fighting fiercely with an ancient monster that looks like a giant gecko in the midst of a snowstorm.

In the air not far in front of the gecko monster, the pale-faced cultivator named Zhong was floating steadily in the air.

He watched indifferently the fierce battle between the ancient beast and many Nascent Soul cultivators below.

After a while, seeing that six or seven disciples had failed to defeat the ancient beast, he finally frowned and decided to join the battle himself.

He was seen quickly making hand gestures and chanting a spell, and in an instant a large amount of dark smoke emerged from his body. These evil spirits soon transformed into two extremely black dragons, rushing towards the gecko monster.

Following closely behind it was a large net that was completely green and emitting dazzling light. As the net closed in, countless green fire balls as big as fists appeared in it, pouring towards the monster.

Accompanied by a series of deafening thunders, black light and green flames intertwined and collided with each other.

After a while, the light suddenly dissipated, and a huge charred body appeared in its place - this was the dead monster.

The old man waved his sleeves lightly, and a hurricane came whistling, sweeping the remains of the ancient beast away from its original position and throwing it more than ten feet away.

Where the ancient beast was, a huge ice crack appeared. This unfathomable ice crack continued to extend downwards, emitting a soft white light, making it difficult to determine where it ended.

"set off!"

The old man spoke slowly, and then his body flashed, and instantly turned into a stream of black light and drilled into the ice crevice.

The other disciples of the Ghost Spirit Sect followed without hesitation and entered one after another.

In this team, many practitioners including Wang Chan and Yan Ruyan were all there, but the leader of the Ghost Spirit Sect and Wang Tiangu were never seen.

Soon after these practitioners from the Ghost Spirit Sect entered the ice crevice, the originally noisy battlefield immediately returned to silence, with only the falling snowflakes silently drifting on the ground.

The corpse of the ancient beast, which had been covered with a layer of frost, was covered by the white snow after a short period of sedimentation, and gradually formed an ordinary snowdrift.

……

In a dense forest area where the Ghost Spirit Sect's disciples had been active before, a woman named Zi Ling stopped somewhere, her eyes cast towards a seemingly ordinary pile of earth in front of her, and she fell into deep thought with a bit of confusion.

After about an incense stick of time, she looked up at the tall trees around her, then lowered her head to examine the pile of earth in front of her.

Then she flicked her slender fingers lightly, and a ball of light flashing with faint fluorescence flew out of her hand.

"boom"

After a low and powerful crash, the original earth pit of about ten feet in radius appeared clearly in front of us.

The pit was filled with a mixture of dark grey fine dust, rolling all over the place, and in the middle of the bottom of the pit, stood a small number of tree roots that had been baked black.

"This must be the place. Although there are many people in the Ghost Spirit Sect, it is much easier to find such a mark."

"But they didn't seem to expect that there were others looking for the same mark, so they left so many traces in such a hurry."

A female cultivator said to herself in a low voice with a look of joy on her face.

After making some slight adjustments, she waved her sleeves again to fill the hole back to its original state, and at the same time took out a green talisman from her palm.

After walking around several giant trees nearby, he suddenly attached the talisman to one of the giant trees. The talisman then burst into a dazzling green light and disappeared into the bark of the branch.

After confirming the direction was correct, she carefully steered the flying sword, transformed into a beam of dazzling light, and disappeared at the end of the sky.

……

In a huge canyon that spans the sky and the earth, an elderly Taoist priest is concentrating on observing the various restrictions at the entrance of the valley, with a thoughtful expression on his face.

Behind him, two puppets that looked like hideous evil spirits stood there quietly, motionless.

Turning his sight to the other side of the canyon, he could vaguely see a large area of ​​blood-red light flickering. This was the main passage leading to the inner valley.

However, this not-too-long canyon is dotted with several extremely powerful ancient prohibitions. (End of this chapter)
