............

Knowing that Du Xuanqing actually had such a magical talent, Du Feiyun was naturally extremely happy.

In the Nine Dragons Ding, there are many medicinal herbs that he collected and excavated, as well as some seeds of precious medicinal materials.

He handed over these herbs and seeds to Du Xuanqing and asked her to plant and cultivate.

Knowing that Du Feiyun's cultivation needs resources very much, Du Xuanqing naturally accepted it gladly, promising not to disappoint Du Feiyun.

In the hearts of Du Xuanqing and Du Shi, Du Feiyun is now the head of the family, and he is the pillar of the family.

The two of them were weak women who were powerless, and they couldn't help Du Feiyun cultivate and kill the enemy, so they could only do what they could, try to help him solve some trivial matters, so that he could concentrate on cultivation.

Du's body is still weak, but fortunately, the spiritual energy in the mountain gate of Liuyun Sect is sufficient, and under the nourishment of spiritual food, his complexion has improved, and his mental state is much better.

Every time he thought of Du Shi's illness and knew that she had less than three years to live at most, Du Feiyun's heart was heavy.

Thirty-six kinds of materials were gathered to refine the Chiyun Pill to alleviate the mother's illness and prolong her life, which is not to be delayed.

It's not just this matter, the most important thing for him now is to immerse himself in penance, improve his strength, and reach the innate realm as soon as possible.

Refining the Chiyun Pill to cure his mother's illness and becoming a true disciple to find Wu Qianchen for revenge, these two things are the top priorities at the moment.

Du Feiyun, who has a clear goal and is very firm in his heart, feels more and more that time is pressing, and he is unwilling to waste time at all.

After returning home, chatting with his mother and sister for a while, and telling them to recuperate, Du Feiyun began to retreat and cultivate.

In the previous battle, he had faintly touched the bottleneck, feeling that he was about to break through the mid-stage realm of qi refining and enter the late stage of qi refining.

He made up his mind that this retreat cultivation would only be able to exit the stage of Qi refining if he reached the late stage of Qi refining.

In the small courtyard where each outer disciple lives, there is a secret room dedicated to retreat and practice, which is convenient for the disciples to meditate.

At this time, Du Feiyun was in the secret room, sitting cross-legged on the futon, his face was calm, no sadness or joy.

In his heart, he was silently reciting the mantra of Qingfeng Xuangong, and the majestic Yuan Force in his body was running.

He had long understood that this Qingfeng Xuangong was an absolute idle exercise, and it was a supreme mastery. Several battles with Qi Refining Stage cultivators made him find that his Yuan Force Purity was more than twice as high as that of monks in the same realm.

Otherwise, he would not have been able to kill Wang Cheng so easily, because the Yuan Force in his body was too majestic.

His cultivation of the Pure Wind Xuangong is twice as strong as that of a cultivator of the same realm, and at the same time, the difficulty of improving the realm is more than twice as high.

Because of this, after he took the Stone Bell Spirit Milk, he would only advance to the sixth level of Qi refining. If it was taken by an ordinary Qi Refining Cultivator, it was likely to directly advance to the late Qi Refining Stage.

Now, touching the bottleneck of the late stage of qi refining, he needs to accumulate a huge amount of Yuan Power, and he needs to accumulate several times the Yuan Qi of ordinary monks in order to successfully advance to the rank.

In front of him, there was a small pile of spirit stones, as well as dozens of Hui Yuan Pills, all of which were the sect benefits that he deserved for a few months of entry.

He planned to cultivate hard, accumulate enough Yuan Power, and then use these spirit stones and Hui Yuan Dan as the auxiliary at the threshold of the impact bottleneck to see if he could successfully advance to the ranks.

In the dark secret room, time passed imperceptibly, and Du Fei sat on the futon without moving, surrounded by vitality.

He is absorbing the aura of heaven and earth with all his strength, transforming it into yuan power and storing it in the dantian, just waiting for the yuan force to accumulate and fill, which is the time to hit the bottleneck.

Ten days passed, and when Du Feiyun's body began to stir up a breeze, the Yuan Force accumulated in his body had reached its peak.

He could already clearly sense that he was standing in front of the bottleneck, and he could reach out and touch that barrier, and if he pierced that barrier like a fetal membrane, he would be able to successfully advance to the late stage of qi refining.

Among the twelve main veins in the body, the Yuan Force is rolling and rushing, like a surging river, faintly emitting bursts of agitation. The infinite amount of power lurks in the body, and it seems that it will be detonated at any time, bursting with great power.

In the human body, there are 12 main veins, and there are 108 veins. ,

The twelve main veins are unimpeded and accumulate enough yuan power, then you can become a cultivator in the refining stage.

If the impact opens the first branch, you will be able to break through the bottleneck of the refining stage and be promoted to a cultivator in the qi refining stage.

Qi refining stage cultivators can open at least six branch veins. When a Qi refining stage cultivator opens the eighteen branch veins, he can advance to the innate stage.

Now, in Du Feiyun's body, twelve branch veins have been opened.

He was using his mind to operate the Yuan Force in his body, flowing towards the thirteenth branch vein, as long as the thirteen branch veins were impacted, he would be able to successfully advance to the late stage of Qi refining.

The surging Yuan Force was like a rolling river, flowing into the thirteenth meridian endlessly, but it was blocked by a thick layer of fetal membranes and could not advance an inch.

Du Feiyun's face gradually became solemn, condensed his mind, mobilized all the yuan force in his body, and began to attack the fetal membrane.

The crimson Yuan force, like a big river, brutally impacted the fetal membrane. The fetal membranes were impacted by the Yuan Force, and suddenly there was a fierce pain, Du Feiyun suddenly frowned, his muscles and green tendons trembled slightly, and he gritted his teeth and did not hum.

As he manipulated the Yuan Force to continuously hit the barrier, bursts of heart-rending pain continued to enter his mind, causing cold sweat to gush out of his body, and the blue muscles on his face jumped wildly.

The pain, like countless sharp knives cutting through the meridians and bones, made people's hearts tremble and make them fearful.

Too many monks, precisely because they can't endure this intense pain, can't break through the bottleneck and can't advance to the ranks.

Du Feiyun was never afraid, let alone thought of giving up. Although the pain was unbearable, the conviction in his heart told him that he could not give up, otherwise he would never stop.

The path of cultivation is a process of constantly challenging oneself, and those who do not have tenacious willpower and cannot defeat themselves will never be able to step into the road of immortality.

"What kind of hardship haven't I experienced Du Feiyun? What pain haven't I experienced? Does this pain want me to retreat?"

"No, I will never give up, I want to improve my strength, I want to become stronger!"

Du Feiyun's heart roared angrily, and his incomparably firm belief made him give birth to tenacious willpower, and he persevered to impact that layer of obstacles with his yuan force.

Once, twice, three times......

For a whole quarter of an hour, Du Feiyun had been hindered at least a hundred times with Yuan Force impacts, and each impact would make his eyebrows pound violently, and the pain would be unbearable.

However, he persevered, and even gritted his teeth and said nothing.

After hundreds of efforts, the thick fetal membrane finally loosened a gap, and the possibility of breakthrough became greater.

Du Feiyun was encouraged and continued to endure the severe pain, impacting the fetal membranes with Yuan force.

However, at this moment, his heart sank. Because, his current Yuan Power has accumulated to the peak, and he can't go any further, and these Yuan Forces alone are far from enough to break through the obstacles.

There is no doubt that Du Feiyun will use the force of external objects to enhance his own yuan force to impact the bottleneck.

His hands grabbed the spirit stone placed in front of him like lightning, held it in the palm of his hand, and absorbed the yuan power in it.

In just half an hour, more than thirty Yuan Li were absorbed by him, turned into powder and dissipated.

At the same time, the Yuan Power in his body increased by three points again, becoming extremely majestic, definitely comparable to the Yuan Power level of a cultivator in the late stage of Qi refining.

However, this is still not enough, it is still not enough to break through the obstacles and break through the bottleneck!

Du Feiyun grabbed more than a dozen Hui Yuan Pills in front of him, stuffed them into his mouth, and then swallowed them, digesting and absorbing the Yuan Force in the pills.

Suddenly, his Yuan Force became even more majestic, increasing by five points.

At this time, the Yuan Force in his body had reached an extremely strong level, and it was three points stronger than that of a monk in the late stage of Qi refining.

It's just that the Qingfeng Xuangong he cultivated, and the physique meridians had been transformed by Shi Zhong's spiritual milk, so the bottleneck was several times more difficult than that of ordinary monks.

The Yuan Force in his body was still not enough to break through the bottleneck! Although the fetal membrane was more loose and more likely to break through, there was still a lack of strength.

Du Feiyun's mind turned rapidly, and he thought of the multicolored python snake gall in the Nine Dragons Ding.

That snake gall is a rare medicinal material at the level of heaven and earth treasure, and it contains an extremely majestic aura, so that he can absorb and refine the aura in this snake gall, and he will definitely be able to break through the bottleneck.

Without hesitation, he took out the snake gall bladder, held it in the palm of his hand, and absorbed the aura from it with all his might.

The pure and rich aura was quickly inhaled into his body and transformed into Yuan Force, providing him with a stronger boost to attack the pass.

Finally, a quarter of an hour later, when the Yuan Power in his body was so full that it almost burst open, he finally stopped absorbing. If he continued to absorb the aura in the snake gall, he was afraid that he would be blown up by the too strong Yuan Force and die.

The majestic Yuan Force that was rolling like thunder swam in the meridians, converging, and rushed towards the thirteenth branch like a rainbow.

Bang!

The torrent-like Yuan Force slammed into the fetal membranes, and suddenly there was a sharp pain that pierced the cone, making Du Feiyun couldn't help but snort.

The two collided, although there was no sound, but the sound like a thunderstorm was still clearly reflected in Du Feiyun's mind.

Fortunately, at the same time as the huge thunderous sound burst out, the mighty Yuan Force finally succeeded in impacting the fetal membranes and surging into the thirteen veins.

Since then, the operation of the Yuan Force has been unimpeded, flowing all the way through the thirteen veins, and returning to the twelve main veins again.

Finally succeeded in breaking through, and his strength was promoted to the seventh layer of qi refining, and he became a late-stage qi refining cultivator.

Du Feiyun let out a long breath, and then his heart relaxed, woke up from his meditation, opened his eyes, and waved his hand to wipe away the cold sweat on his forehead.
