When Chen Yun captured the six-winged frost centipede, he did not know whether this type of spiritual insect could rely on the colorful grass to complete the process of devouring and evolving each other.

He was just trying this out of a trial mentality.

However, what was gratifying was that this spiritual insect really had such mysterious evolutionary properties, which made Chen Yun overjoyed.

Previously, Chen Yun intended to use the coldness of this spiritual insect to assist in the practice of the Purple Heavenly Fire.

However, after experiencing the battle in the Demon Valley, a new idea suddenly emerged in Chen Yun's mind.

Although the gold-eating bugs have extremely powerful attack power, their flying speed is relatively slow. If they are carefully bred in the future.

When encountering fast-flying enemies or special scenarios, you will still be greatly restricted.

On the other hand, the six-winged frost centipede occupies a very high position on many lists of strange insects.

It's not just because of its amazing ability to spit out cold air, but more importantly, its extraordinary flying speed.

It is said that in the initial stage of having two wings, the flying speed of this kind of spirit insect is already comparable to that of other ordinary spirit insects.

However, when a pair of shells grew on the tail, the number of wings increased to four pairs, and the flying speed was greatly improved, surpassing that of ordinary magic weapons by several times.

However, the most frightening moment was when this spirit insect suddenly grew another pair of shells.

Its flying speed is enough to rank first among all kinds of spiritual insects. It is said that it can come and go without a trace and fly thousands of miles away in an instant.

Of course, all of the above are legends recorded in classics.

Even in ancient times, spiritual insects that could successfully evolve into a six-winged form were extremely rare.

Chen Yun was skeptical about this proposal.

However, there is no doubt that the six-winged frost centipede is an ancient spiritual beast with extraordinary speed.

In the life-and-death duel between Chen Yun and the ancient demon, he had tasted the bitterness brought by his opponent's ghostly movements.

So he began to consider how to cultivate the six-winged frost centipede to the highest level.

Moreover, when this spiritual insect reaches the six-winged state, the cold breath it emits will inevitably become more intense, which will be of great help to his cultivation of the Purple Sky Fire.

With this idea in mind, Chen Yun naturally developed a strong interest in the larvae of these six-winged frost centipedes.

Seeing that the larvae did not show any signs of rejection of the new environment, Chen Yun's worries were finally alleviated.

Just when he wanted to observe for a while longer, his expression suddenly changed. He turned his head and looked towards the cave gate, as if he had noticed something unusual.

Then, his eyes flashed with a gleam of light, and he waved his sleeves. A white light rushed out, and Yin Yue appeared before his eyes.

"Mu Peiling has arrived outside the door. Please lead her to the hall. I have something to say to this girl."

Chen Yun ordered in a serious tone.

"Yes, master!" Yin Yue answered respectfully without asking any further questions, then turned into a stream of silver light and disappeared on the spot.

Chen Yun sealed the insect room again and then leisurely returned to the hall.

A moment later, Chen Yunduan sat on the main seat in the middle of the hall, holding his chin with both hands, and fell into deep thought.

At this moment, there were slight footsteps coming from the door of the hall.

Yin Yue walked into the hall first with a smile on her face, and Mu Peiling, who had not been seen for many years, followed closely behind.

The woman's appearance was still beautiful, even more charming than before. Her original cold temperament was much reduced, replaced by a kind of otherworldly charm like an orchid in a valley.

"Greetings, young master. Congratulations on your safe return and great improvement in your cultivation, successfully advancing to the middle stage of the Nascent Soul."

When Mu Peiling saw Chen Yun, a faint smile appeared on her face and she bowed slightly.

"You congratulated me on my advancement to the middle stage of the Nascent Soul right after we met. It seems like you already know something about me. You don't have to be polite."

"Back then, you accompanied me to the Far West. Although you didn't achieve any great military achievements, you also worked hard. There's really no need for us to be too rigid about etiquette."

Chen Yun smiled at the woman, then motioned for her to stand up and talk.

The three years they spent in the Far West helped to ease the relationship between them.

Although it has not yet reached the point of close intimacy, it has at least made great progress compared to the past.

"Thank you for the compliment, sir!" Mu Peiling stood up gracefully.

"We had just returned from the Far West that year. I never expected that after just a short separation from you, I would be trapped in the Fallen Demon Valley for more than twenty years."

“It’s really touching that you’ve been able to stick with this place.”

"As your concubine, I have received your great kindness. If I had not stayed here and waited, where would I go? Moreover, I have always believed that you would never die easily."

Mu Peiling responded with a smile on her face.

"I didn't expect you to trust me so much. However, this experience was a life-and-death experience, and I almost didn't make it back alive. On the other hand, although you have elixirs to assist your practice, your cultivation level has improved at an astonishing speed."

"I wonder if you have enough confidence in the upcoming stage of forming a pill?"

After Chen Yun laughed, he changed the subject and asked about Mu Peiling's practice.

"I really don't dare to speak rashly. The probability of forming a pill is already very small. Whether or not you can successfully form a pill depends entirely on God's will."

Hearing this, Mu Peiling showed a helpless expression on her face.

"Is this really God's will? Haha, this matter really cannot be easily judged."

"I can increase the possibilities for you in the later stages of foundation building, so that you can achieve a greater chance of success on the road to forming a pill."

Chen Yun said this to the woman with a smile.

"What? This is unbelievable. Are you kidding me, sir? I have never heard of such a miraculous elixir existing in the southern part of the world."

Mu Peiling opened her red lips slightly and asked in surprise.

"Most of the spiritual medicines I have are not from the Tiannan region. It is understandable that you have not heard of them."

"However, I can assure you that as long as you take these elixirs according to my advice, your chances of forming a pill will be close to half, which is not surprising!"

Chen Yun looked calm and replied calmly.

Mu Peiling has known Chen Yun for a long time and knows that he never speaks nonsense, so she has about 70% trust in him.

However, after a brief thought, she still felt a little hesitant.

"Since you have told me all these things, do you have any other instructions? If there is anything, please tell me directly."

Mu Peiling said in a low voice.

Chen Yun was slightly surprised, but after a moment's thought, he stopped beating around the bush:
"Do you still remember what we agreed on?"

He got straight to the heart of the matter at the outset.

"Of course I remember. My Lord promised to give me thirty years to practice, and he will not ask for my Yuan Yin body during this time." Mu Peiling was stunned at first, then a faint blush appeared on her face, making her look exceptionally beautiful.

"The agreed deadline is coming soon. But please don't worry."

"I will never embarrass you at the critical moment of your Dan Formation."

"But before we form the elixir, we need to clarify certain matters to avoid disputes."

"I will give you enough time to weigh the pros and cons."

"I don't want to waste my efforts in helping you become a Jindan cultivator, but I will never allow you to choose to betray me and harbor resentment in the end."

Chen Yun knew that this situation might cause misunderstanding, but he still explained patiently.

"May I ask what you mean, sir?"

Mu Peiling's heart trembled, and she couldn't help but look up at Chen Yun, with a gleam of doubt in her eyes.

"I hope that after you achieve Dan Formation, you will give up your original cultivation method and practice a secret method called 'Dian Feng Pei Yuan Gong' instead."

Chen Yun said with a mysterious smile.

"Dianfeng Peiyuan Gong?" Mu Peiling was quite surprised.

"This is an extremely rare dual cultivation technique for women only. When one reaches a very high level of cultivation, the first fusion of yin and yang can be used to greatly enhance the strength of both men and women."

"Although the effect on improving cultivation is relatively minor, it is a strong help in breaking through bottlenecks."

"But please note that the main practitioners of this technique should be women, and it is often men who benefit the most."

"That's why, before this, I have been trying my best to make it up to you and fully support you in building your foundation."

"Because for me, the Dianfeng Peiyuan Gong required to climb to the late Nascent Soul stage can only be effective after practicing to the late Jindan stage."

"As long as you agree to switch to practicing this technique, after you form the elixir, I will continue to provide you with the elixirs needed for the foundation-building stage to help you practice faster."

"As for whether you can practice quickly after forming the elixir, I cannot make a definite guarantee, but at least I can save you more than a hundred years of hard practice."

"Of course, if you have concerns about this, Chen will not force you."

"After you complete this Dan formation attack on your own, regardless of whether you have formed a Dan or not, I will remove the restrictions in your body and restore your freedom. From now on, we will go our separate ways and not infringe on each other."

Facing Mu Peiling's reaction, Chen Yun's expression remained the same as before, and he calmly expressed his thoughts.

When Mu Peiling heard these words, she was shocked, her emotions were in turmoil, and the expression on her face kept changing.

"Those who practice the Dian Feng Pei Yuan Gong must maintain their virginity. Female practitioners must always remain virgins, otherwise once they lose their virginity, all their previous efforts will be wasted."

"Therefore, before you are promoted to the late stage of Jindan, I will not ask you to serve me in bed."

"Just maintain this kind of relationship between you and me."

"Of course, if you can really help me break through to the late Nascent Soul stage, I can promise you that I will do my best to help you condense your Nascent Soul in the future."

"With the help of a late Nascent Soul cultivator, it is not out of your reach to condense your Nascent Soul."

Chen Yun stared at Mu Peiling and spoke in a calm tone.

These words are not empty words. If Chen Yun's cultivation reaches the late Nascent Soul stage, he will be fully capable of collecting the eighth-level demon grass again and re-refining the Nine-bend Spirit Ginseng elixir that will be of great benefit to the formation of the Nascent Soul.

After all, at that time, the eighth-level monster could no longer pose much of a threat to him.

Mu Peiling lowered her head and pondered for a moment, then raised her jade-like face and asked Chen Yun:

"Sir, is the process of practicing this peak Pei Yuan Gong extremely slow and does it have hidden dangers that are difficult to cure?"

"No, this technique is not as powerful as top-level techniques, but its progress is several times faster than ordinary techniques. There are no potential risks."

"The only problem is that when we fight with others, we may suffer some losses."

Chen Yun responded decisively.

"In this case, Pei Ling will obey your arrangements. I know my own qualifications very well."

"If it weren't for the help from you, the chances of successfully forming a pill would be extremely low. As for the Nascent Soul stage, it's beyond reach."

The woman looked at Chen Yun firmly and spoke calmly.

"I am glad that you can give such an answer. You should know me well after getting along with me for so long. Although you are only a concubine, I will never ask too much of you."

"You just need to focus on preparing for the formation of the elixir, and I will send you the necessary elixirs when the time comes."

Chen Yun's face was calm, as if he had already foreseen the woman's decision.

"I am so grateful for your kindness, sir! A drop of kindness should be repaid with a spring, Pei Ling knows this very well. I am willing to follow you for the rest of my life."

Mu Peiling saluted again, with a determined look on her face.

At this moment, Mu Peiling has just truly decided to rely on Chen Yun, and no longer has any worries about gains and losses.

After all, there is no other example like Chen Yun, who possesses supernatural powers comparable to those of the three great cultivators and shows so much care to his concubines, in the entire Tiannan region.

At the same time, this woman also deeply understood that the favor Chen Yun had bestowed on her was extremely heavy.

Without the help of the elixir given by Chen Yun, even if he was currently trying to form a pill, he would probably still be struggling in the middle stage of foundation building.

Therefore, Mu Peiling did not hesitate and immediately agreed to the conditions proposed by Chen Yun.

After Chen Yun told the truth, the relationship between the two of them instantly became closer.

After that, whenever this woman talked with Chen Yun again, her expression revealed a deep sense of intimacy.

Afterwards, Chen Yun happily gave detailed answers to questions from those who came to ask him about Dan.

Mu Peiling knew that the opportunity was not to be missed, so she listened attentively to Chen Yun's teachings, not daring to relax for a moment.

After nearly half a day of teaching, Mu Peiling felt that she had gained a lot, so she said goodbye to Chen Yun and left.

Considering Chen Yun's teachings, she still has many shortcomings and needs to make adequate preparations in advance.

Chen Yun did not try to keep the girl for too long. He just gave her a few words of advice and warning before letting her return to Zifeng.

Yin Yue personally escorted the woman out of the cave.

When she returned to the front hall again, she found Chen Yun still sitting on the chair, but there was an exquisite jade slip in his hand.

He was using his spiritual sense to carefully explore the information contained in it. This was the jade slip that recorded the method of refining a replica of the Seven Flame Fan.

"Master, are you really determined to help this woman cultivate all the way to the late Jindan stage?"

Yin Yue walked quietly to Chen Yun's side and asked in a low voice.

"Why do you have such doubts?" Chen Yun withdrew his consciousness and asked with a frown. (End of this chapter)
