When all these spirit stones were absorbed, the mysterious jade pendant suddenly trembled, and let out a strange buzz, only to see it flicker, the surface runes flowed, and a milky white pillar of light shot out from it, hitting the empty stone wall in front of it. （)

Airplanes!

Hearing a buzzing and trembling, the stone wall in front of him began to decompose at a rapid speed, and in the blink of an eye, a passage of dozens of zhang came into view again.

"I didn't expect it to have such a great power, Cheng Mou will need a while to dig such a distance, it just has this effect with one blow, it is really eye-opening!"

Seeing this scene, Cheng Qian's complexion changed slightly, which was many times faster than the speed of his own digging!

However, after the jade pendant struck, it did not stop, but under the flash of spiritual light all over the body, the large and small rune packages shrank and swelled, and they shot into the depths of the passage with a 'whoosh'.

After a while, under the repeated excavation of the jade pendant, there was already a distance of more than 500 zhang, but a lot of spirit stones were dug up in the middle, but the jade pendant turned a blind eye, as if he did not see it.

As the digging got deeper and deeper, more and more of the best spirit stones appeared, but the jade pendant did not mean to absorb them, but continued to excavate, directly ignoring these top spirit stones.

Seeing this, Cheng Qian could only follow the jade pendant all the way, looking at the high-grade spirit stones and the best spirit stones that flickered around him, his heart was pounding, these things were all what he needed, since the jade pendant was not absorbed, he would easily pocket the best spirit stones everywhere he passed.

A moment later, Cheng Qian had more than three hundred top-grade spirit stones in his hands. He didn't pick up those high-grade spirit stones, because the jade pendant flew too fast, and he could only follow closely.

However, as he went deeper, the way out behind the cave where Cheng Qian was located had been blocked by spirit stones. Although the spirit stone is made of mountain stones, it is impossible to pass through the spirit stone mine by performing the earth escape technique, which is not allowed by the laws of heaven and earth.

"Where is it going?" Cheng Qian's face showed a hint of solemnity, although all the top-grade spirit stones for repairing the Medicine King's Five Spirit Diagram had been collected, the jade pendant swept down rapidly, and there was no intention of stopping at all, so he had to follow it hard.

Soon, I don't know how long I followed Yu Pei. Cheng Qian's face gradually showed a trace of impatience, and now he has already exceeded a thousand zhang distance underground, and all sides are top-grade spirit stones, and the way out from the rear does not know how many spirit stones are blocked.

The thought of the rear way out was blocked. Cheng Qian was a little irritable in his heart, and at the same time, he was also curious in his heart, what was it that could be so valued by Yu Pei that he even abandoned the best spirit stone.

After half a cup of tea. At this moment, Cheng Qian has gone thousands of zhang deep into the ground, and the walls above his head are all made of spirit stones, and it is impossible to pass the Five Elements Escape Technique, and if you want to go out, you can only go back and dig back step by step.

Poof!

Cheng Qian was thinking like this. Suddenly, an entrance suddenly opened in front of him, and he followed Yu Pei forward. He didn't pay attention for a moment, and fell through the entrance.

Boom!

Come out of that hole. Cheng Qian's body quickly fell into a spiritual stone field, making a muffled sound.

Cheng Qian shook his head for a while, then raised his head, and his expression was stunned at this look, surrounded by a wide karst cave.

However, the liquid with a thick aura floated everywhere in the cave, and the clothes on his body also appeared a little cold.

This cold feeling proved that his clothes were wet, and Cheng Qian muttered with a stunned face: "The aura here is even thicker than outside, and even the clothes are wet!"

Surprised for a while, Cheng Qian hurriedly stood up, looked around, and saw that the ground was covered with top-grade spirit stones, and the mountain stones that could store zài in this kind of aura would naturally become the best spirit stones. ...,

At this moment, Cheng Qian did not mean to collect the best spirit stone, but instead released his divine consciousness outward, and investigated around, but Cheng Qian's divine consciousness was blocked back by an invisible resistance as soon as it was released, and in this place where the spiritual energy was extremely condensed, he couldn't even release his divine sense, and could only wander around ten zhang.

If you can't release your divine sense, you have to spend a little more means to know how big this underground cave really is.

Cheng Qianzhi held his forehead with his hand, stepped on the top of the best spirit stone, paced back and forth, but his face was extremely gloomy, after falling in from the hole on the top, the mysterious jade pendant also lost its trace, but in this cave, this is understandable.

What attracted this jade pendant to come here?

Thinking like this, but without the slightest clue, Cheng Qian sighed lightly, and slowly moved forward in this unknown cave.

At the same time, the blue eyes at the center of his eyebrows also opened suddenly, and his divine sense was useless, and he could only use the secret technique of spiritual eyes.

Sure enough, after using the Spirit Eye Secret Technique, the condensed aura could not block his vision.

I saw that in the hazy place ahead, there were pieces of white light flashing, which looked extremely weird, Cheng Qian did not hesitate when he saw this, and walked forward quickly with a flash of his body.

As he walked deeper and deeper, the aura around him became more and more condensed, which also made every fur on his body moistened by the aura.

Airplanes!

Before he really got close to the white spiritual light, a low humming sound came into his ears, and the pure aura also came to his face, and the condensation of this spiritual energy had already surpassed the best spiritual stone, which made Cheng Qian feel incredible.

"Hey, that's!" Cheng Qian's eyes were closed, leaving only one blue eye to look at it carefully, but he could see that something was wrong.

The thing that surged with white light was the jade pendant on the chest, and at this moment there were white rocks suspended around the jade pendant, the surface of these rocks was extremely smooth, and it was only the size of a palm, and it exuded a mysterious aura under the rotation of the jade pendant.

Cheng Qian closed his spiritual eyes, slowly opened his eyes, narrowed slightly, and said with a solemn expression: "This breath seems to be...... Vitality Tribulation!"

Slowly recalling this breath, suddenly his face changed wildly, and he didn't know what he remembered.

This aura is the same as the aura that diffuses from the clouds when he met the monk of the Transformation Stage when he was in Shenlongjian back then, and when Dongfang Changao resisted the Heavenly Tribulation.

The Sky Devouring Demon Wolf was able to wake up in the first place, precisely because of this breath.

"This is the qi of the immortals!" Cheng Qian's face changed greatly, and he spoke again incredulously: "How is this possible, how can the human world give birth to the qi of the immortals!"

As the name suggests, the aura of the immortal spirit is the aura used by the immortals, not by the immortal cultivators, this kind of thing is only available in the true immortal realm.

Occasionally, there will be immortal qi in the human world, because of the laws of heaven and earth, when the monks of the god transformation period cross the tribulation and ascend, they will produce a dense immortal qi to open the spatial channel.

However, there is no one here to cross the tribulation and ascend, let alone a true immortal realm, why is there such a strange aura?

Cheng Qian didn't dare to step forward, let alone absorb this breath, although it was the qi of the immortals, with his current cultivation to absorb this breath, even a little bit would make him explode and die.

He only stared quietly ahead, and did not step forward again.

Soon, between the flickering of those white stones, a majestic immortal aura erupted, and the mysterious jade pendant suddenly absorbed this breath as soon as it turned down.

Seeing this scene, Cheng Qian's heart couldn't calm down anymore, what was this jade pendant, even absorbing the qi of the immortals?

After only a few breaths, the stones that were originally flickering with white light became lifeless at this moment, as if the spirit stones had been absorbed. ...,

"This should be an immortal stone!" Cheng Qian gasped when he saw this, and the blood in his body began to boil, if the best spirit stone is the top order, what about the immortal stone?

Thinking of the value of the immortal stone, Cheng Qian's heart couldn't be calm, and he looked around, only to see that under the mysterious jade pendant, there were actually three immortal stones scattered on the ground.

Soon after the jade pendant absorbed the immortal qi, it suddenly let out a sharp buzz, and with a flash, it disappeared without a trace.

Then the white light flashed on Cheng Qian's chest, and the mysterious jade pendant reappeared on him, and when the jade pendant returned to his chest, it was no longer as cold as it was at the beginning, but a warmth slowly overflowed from the jade pendant.

This warmth is more condensed and majestic than the warmth he had when he was a child.

Cheng Qian stretched out his right hand and stroked the warm jade on his chest for a while, and his face showed a smile: "It seems that the aura in the jade pendant has recovered to a full state, but the monster sealed in the jade pendant, Cheng will know sooner or later, I remember that the Nine Abyss Tiger Trick said that in the middle of the Yuan Infant period, you can solve the secret of this jade pendant!"

Thinking of this, Cheng Qian also forcibly suppressed the excitement in his heart, slowly took a few steps forward, glanced at the seven or eight immortal stones that had turned into waste stones around him and shook his head.

Then he turned his gaze to the three remaining immortal stones on the ground, with a hint of joy on his face, and hurriedly walked over, picked up all three immortal stones, and put them in the palm of his hand to observe them carefully.

It was cold in his hand, but he could feel the majestic aura inside, and Cheng Dù, who was condensed with aura inside, was not something he could absorb at all, if he absorbed the immortal qi inside to cultivate, the only result would be to explode and die!

"Since I can't use it now, then I'll keep it, although the only purpose of an immortal cultivator is to ascend to the True Immortal Realm and live with the sky, but how many people have done it?" Cheng Qian held the immortal stone in his hand and thought like this, and after sighing lightly, he collected the immortal stone in his hand.

Looking around, Cheng Qian looked to see if there were any other immortal stones, but after a few hours, he didn't find any other immortal stones, and there was nothing else here except for the best spirit stones and a culvert that kept coming out of the spiritual energy.

Cheng Qian knew that the entrance of the cave was the spiritual spring, and there was no need to explore it.

Since he couldn't get out in a short time, Cheng Qian simply sat cross-legged in the spirit stone ground, and with one hand on his waist, under the flicker of spiritual light, a strange picture scroll appeared, and then it opened by itself, and a strange space door appeared in the painting.
