In the cave, Chu Feng looked inward.

The three strands of true qi were based on one side of the dantian, among which the gray Underworld True Qi was quietly dormant, like a hidden dragon motionless in the abyss, while the black Demon Dao True Qi was constantly tumbling, and seemed to be showing its violent attributes all the time; as for the purple Righteous Dao True Qi cultivated through the Purple Qi Dongyuan Sutra, it gave Chu Feng a sense of neutrality and vastness.

Feeling the power of the three true qi inside, Chu Feng had a whim, intending to impact the first level of the Pulse Transformation Realm, the Yin Seesaw Pulse!

There are a total of eighteen acupuncture points in the Yin stilt vein, and the so-called impact of the Yin stilt vein refers to the re-training of the eighteen acupuncture points in the Yin stilt vein with strong true qi, removing its acquired turbidity, stimulating the innate power of yin stilt contained in it, integrating it into itself, and strengthening its own true qi attributes.

However, in the process of impact and refinement, the eighteen acupuncture points of the Yin Seesaw Vein will all rely on the innate essence contained in them to produce great resistance and resist independently. Once you can't do it in one go, even if only the last acupuncture point is not completely cultivated, it will be a failure in the end.

In addition, the difficulty of the next impact will become greater!

He did it when he thought of it, but which kind of True Qi to choose for impact training, Chu Feng hesitated again.

Originally, in Chu Feng's opinion, the purple true qi transformed by the Purple Qi Dongyuan Sutra was the best and the most upright, but Chu Feng was afraid that the purple true qi was not domineering enough and would not succeed in one fell swoop.

As for the true qi of the underworld, to be honest, although it was Chu Feng's own cultivation, Chu Feng always had a feeling that he couldn't see through it. Therefore, Chu Feng finally chose the black Demon Dao True Qi, after all, the domineering and sharp reputation of the Demon Dao True Qi is outside.

Moreover, even if there is an abnormality in the process of impacting the Yin Seesaw vein, it is convenient to call for help!

Under Chu Feng's control, the true qi of the Demon Dao that had been constantly tumbling suddenly condensed together, and then set off from the dantian and rushed to the first acupoint of the Yin Seesaw Vein.

"Refine!" Chu Feng shouted in his heart, and the black Demon Dao True Qi immediately launched an impact towards the Ran Gu Acupoint, and the Ran Gu Acupoint, which was originally unable to see the abnormality, immediately rose an invisible force, blocking the penetration of the Demon Dao True Qi.

Chu Feng knew that he had to be strong enough at this time, otherwise, even the first acupuncture point would have to be rubbed, and what would he do with the seventeen acupuncture points that were more resistant?

Chu Feng increased his strength to stimulate the true qi of the Demon Dao, and a sore feeling came from Chu Feng's body, but Chu Feng was relieved to find that the resistance of the Ran Gu acupoint was rapidly decreasing.

Finally, a 'snap' sound sounded like nothing, and Chu Feng's demonic true qi seeped into the Ran Gu acupoint in one fell swoop. Strands of invisible impurities were forced out of the Rangu acupoint and seeped out onto Chu Feng's external skin through the transportation of qi and blood.

In addition, streams of innate yin stilt essence qi erupted from the Rangu acupoint, but these innate yin stilt essence qi did not merge into Chu Feng's demonic path true qi, but retreated at an extremely fast speed, submerging into the Zhaohai acupoint behind the Rangu acupoint.

Then, without waiting for Chu Feng's demonic true qi to attack, Chu Feng's Zhaohai Cave was shocked, and a layer of stronger obstructive power instantly gushed out.

Chu Feng didn't dare to slack off, the powerful Demon Dao True Qi rushed straight away with an indomitable momentum, the two sides were stalemate for a while, and a large number of impurities were thrown away in the Zhaohai Cave, and the innate Yin Stilt Essence Qi hidden in it also reappeared!

......

With the passage of time, Chu Feng's demonic true qi was like a wave of anger, and he successively broke through Ran Valley, Zhaohai, Jiaoxin, Yin Valley, and Heng Valley...... In the end, only one last one remains!

But the resistance that could not be allowed to rise was so strong that it was outrageous, allowing Chu Feng to use the impact of the Demon Dao True Qi wave after wave, just standing still!

And after a series of high-intensity consumption, Chu Feng's Demon Dao True Qi also began to decline, and the power of the impact became lower and lower.

Chu Feng's brows furrowed, and after taking a deep breath, he was about to do his best to take a look, but at this moment, the other two true qi in Chu Feng's dantian suddenly shook.

Immediately, in Chu Feng's unbelievable eyes, two true qi, one gray and one purple, swept out at the same time, passing through the valley, shining on the sea, and passing the letter...... In the blink of an eye, it came to the last point of intolerance.

Chu Feng's heart moved, could it?

Sure enough, the three true qi gathered together, and it was the first time that they cooperated with each other, and they were entangled with each other and rushed to the last inadmissible point.

And with the addition of two true qis, the seemingly indestructible resistance of the incomprehensible acupoint became shaky in an instant, and after holding on for a few minutes, it shattered, followed by a massive amount of innate yin stilt essence qi that erupted like a fountain.

The three true qi separated in an instant, and they immediately started to compete with each other, as if everyone knew that this yin stilt essence was a great supplement!

Chu Feng was immediately dumbfounded, and his face became ugly. It was only because the three true qi were fighting for the innate yin stilt essence qi that they were frantically confronting each other, raging everywhere in Chu Feng's body, making Chu Feng miserable.

Sweat rolled down from Chu Feng's forehead, and a trace of blood also overflowed from the corner of Chu Feng's mouth, Chu Feng smiled bitterly in his heart, endured the pain, calmed down, and ran the cultivation exercises, wanting to appease the three true qi through the cultivation exercises.

However, it was difficult for a monk to do two things, and Chu Feng could only run one exercise at the same time at most, so Chu Feng's actions were in vain, on the contrary, the three true qi were stimulated to fight each other more fiercely!

Seeing that Chu Feng was about to be unable to support it, at this moment, the blood flag on Chu Feng's waist suddenly shook, soared into the air, spread out above Chu Feng's head, and followed by a large area of blood light pouring down, enveloping Chu Feng.

This blood light contained a strange power, which was frantically repaired in Chu Feng's raging body, and the aromatic fragrance quickly spread in Chu Feng's cave mansion.

Chu Feng was soothing himself, and an abrupt and more intense blood light shot directly at Chu Feng's eyebrows, and at the same time, blood-colored words manifested in Chu Feng's mind.

Taixuan Heart Sutra!

The human heart thinks that it is mortal, the heart of heaven is in the mystery, the human body is the tripod, and the ten thousand tripods are in the world. With Xuan to control Ding, Ding Town is turbid......

Chu Feng was shocked to find that the words that suddenly appeared in his mind were actually a supreme cultivation method. But this mental method cannot cultivate true qi, but is used to amplify one's own wisdom, to distract oneself from manipulation, and to control oneself!

In other words, once he comprehended this Taixuan Heart Sutra, Chu Feng would be able to cultivate and control his three true qi at the same time!

This is definitely a great thing for Chu Feng!

Chu Feng hurriedly put aside everything, concentrated on comprehending, and subconsciously used it after gaining something.

Unconsciously, the three uncontrolled true qi in Chu Feng's body gradually became calm, and each of them absorbed the innate yin stilt essence qi step by step. And Chu Feng's body gradually exuded a mysterious aura.

Suddenly, a black shadow rushed into Chu Feng's cave mansion. At a glance, seeing Chu Feng's current state and the blood flag hanging at Chu Feng's top door, the black cat was shocked.

"So quickly, you stepped into the vein, and the blood flag actually took the initiative again...... Good!good!good!". After sighing, the black cat sat quietly at the entrance of the cave, waiting for Chu Feng to wake up.

Finally, the innate Yin stilt essence spewed out by the eighteen acupuncture points of the Yin Stilt Vein was swallowed by Chu Feng, and it was divided into three parts and merged into Chu Feng's three true qi. Chu Feng also temporarily ended his comprehension of the Taixuan Heart Sutra and opened his eyes.

"Hei Ye, are you back?hehe, do you know?I broke through!I have become a monk of the Pulse Transformation Realm!" Chu Feng's face was full of excitement, and he didn't realize that the blood flag on his head was quietly tied up and returned to his waist.

The black cat knew the strangeness of the blood flag, and it didn't break it, but just said with relief, "Well, it's very good! Chu Feng will not stay in the pulse transformation realm for too long if he thinks at your speed! But for monks, just cultivating to the realm is far from enough! You need a lot of actual combat, a lot of fighting, and you can transform your cultivation into real combat power!"

"And your body needs to be strengthened. You must know that in the world of monks, the flesh is like a ship, and the cultivation is like a sailor. The ship is not strong enough, and no matter how fast the sailor rows, it is useless, and it will be destroyed in the water at any moment!"

"Therefore, you still need to find a body refining technique that can strengthen your physical body in the future! And now, if the conditions are insufficient, you have to rely on external forces to sharpen it!"

"I've decided to take you to the Yin Wind Cliff, what do you think?"

"Yin Wind Cliff?" Chu Feng was taken aback, after staying for so many days, Chu Feng also knew a lot about some things that should be known, so Chu Feng's tone was a little difficult.

Seeing this, the black cat couldn't help but exclaim, "Chu Feng, if you don't endure all the hardships, where can you become a master? Where can you control your own destiny? You don't mean .......?"

"Okay, I'll go!" Before the black cat finished speaking, Chu Feng interrupted it, and then Chu Feng said to the black cat, "Hei Ye, it is necessary to go to the Yin Wind Cliff, but I think before that, I had better go and talk to Elder Feng Feng first." Perhaps, when Elder Fengyu saw my rapid progress, he would give me some pills. ”

"Yes. The black cat nodded.

Coming to the quiet courtyard where Feng Qian lived, Chu Feng stood outside the courtyard and said respectfully, "Disciple Chu Feng, please see the elder!"

"Oh, Chu Feng, come in!"

There was a slightly surprised voice from the courtyard, it had been so long since Chu Feng received the pill, but it was the first time he came to him.

Chu Feng pushed open the courtyard gate, only to see that the courtyard was extremely simple, except for a few potted plants in the corner, there was a stone table, a few stone chairs, and a weapon rack erected in the courtyard. But it's simple, and the yard is quite clean and tidy.

At this time, Feng Qian was slowly walking out of the house, and when he saw Chu Feng for the first time, Feng Feng was shocked, and his eyes shot out a compelling brilliance.

"The pulse is heavy!"

"Yes! Thanks to the strong cultivation of the elders, otherwise, in such a short period of time, the disciple would never have been able to take this step!" Chu Feng was very good at talking, with a grateful smile on his face.

Feng Yu nodded, and while signaling Chu Feng not to be restrained, he said, "Chu Feng, you didn't disappoint Elder Ben, is there something wrong with you coming this time?" If so, just say it directly, Elder Ben will definitely do his best!"

"Thank you, Elder. That's the case, the disciple decided to go to the Yin Wind Cliff to sharpen it...... In addition....... other disciple's elixir has been exhausted. Chu Feng seemed a little embarrassed, but Feng Yu frowned.

"You're going to the Gloomy Wind Cliffs, that's not a good place!"
