A year has passed in a hurry......

At the foot of Diling Peak, the gate of the cave opened silently.

Xia Yin, who was full of scum, stepped out.

At this time, Xia Yin looked unkempt, but his eyes were scorching, and his body exuded a strong and violent aura, like a fierce beast that chose people to devour.

Coming to the outside of the cave and looking at the green medicine garden, Xia Yin moved his muscles and bones slightly, and the violent and abusive aura on his body slowly disappeared......

If there were other monks present, they would find that Xia Yin at this time was already at the eleventh level of Qi refining.

As the aura of tyranny and cruelty completely subsided, Xia Yin's whole person became without a trace of mana fluctuations, just like a mortal.

"Huh...... I didn't expect that the Five Qi Returning Yuan Gong would have the wonderful use of astringent breath!"

Xia Yin's face showed a touch of joy.

At this time, even if the foundation building monk used the Heavenly Eye Technique, he might not be able to see through his own breathing technique, and in the eyes of others, Xia Yin was still the Xia Yin who was at the fifth level of Qi refining.

As for the Jindan monk, because his sense of the five elements of heaven and earth is very sensitive, Xia Yin can't guarantee that he won't be seen through by the other party......

In the past year, relying on the continuous ripening of the elixir from the young shoots, Xia Yin has been spending time in alchemy and cultivating the Five Qi Returning Yuan Gong.

With the repeated refining of a large number of pills, Xia Yin already had a lot of insights on the Dan Dao, and when he refined five or six ordinary pills, he was also very handy and rarely failed.

Moreover, all the pills are refined with elixirs that have matured to a hundred years, and the effect is far beyond ordinary pills.

This made Xia Yin's mana cultivation grow rapidly at an incredible speed, and in just one year, he actually broke through the sixth-layer realm in a row!

Unexpectedly, Xia Yin found that during the cultivation process, some of the mana automatically integrated into the five internal organs, constantly refining these fragile organs.

Moreover, almost half of the mana, when running the Five Qi Returning Yuan Gong, it automatically merged into a hidden meridian in the big spine, and this hidden meridian was constantly rushed away.

Now Xia Yin's dantian qi sea has been connected to the hidden meridians in the big spine.

Xia Yin didn't know what this meridian was called and what it did, so he had always been reluctant to waste mana to impact this meridian.

But once the Five Qi Returning Yuan Gong is operational, half of the mana will automatically rush towards this meridian and expand it.

Now there is a clear vein between the dantian qi sea and the big spine......

Moreover, Xia Yin guessed that the large spine runs through the body, and since this meridian is hidden in it, it should also follow the spine and go directly to the brain soul knowledge sea, and it may even be a hidden bridge between the dantian qi sea and the soul knowledge sea.

It's just that this meridian is hidden and occluded, and ordinary monks can't open it up in their lifetime.

And the Five Qi Returning Yuan Gong obviously has the effect of opening up the mysterious meridians.

Moreover, Xia Yin guessed that the so-called "Five Qi Returning to the Yuan" should refer to the process of attributing the five elements of mana in the dantian qi sea to this meridian and forcibly opening it up.

Now, the lowest part of the spine has been opened up and connected to the dantian qi sea, but there is still a whole hidden meridian in the large spine, which is still occluded.

Over the past year, Xia Yin has been very sad, half of the mana he has cultivated has been wasted on his internal organs and this hidden meridian!

If it weren't for the fact that the internal organs and meridians consumed a lot of mana, Xia Yin believed that he was already at the peak realm of the twelfth layer of qi refining, and he might even have successfully built a foundation......

However, on the whole, this year's realm improvement is still very surprising!

The appearance of mysterious shoots has broken the curse of hopelessness in building a foundation in this life!

This year's cultivation speed is even much faster than those so-called demons.

The most important thing is that he is a cultivator of the five elements of mana, and if he talks about mana alone, he is at least five times stronger than any monk of the same level......

The only thing that worries Xia Yin is that he has taken a large amount of dark green pills in the past year, and his temperament has become inexplicably manic, and his body seems to be a dormant beast!

If it weren't for perseverance, Xia Yin would probably have been influenced and turned into a murderous person.

And such a transformation is caused by the strange aura that melts into the flesh and blood of the meridians when taking the pill.

Every time he took the pill, a strange aura would melt into the flesh and bones, making Xia Yin feel hot all over, and the blood flow rate would speed up a lot......

At this time, Xia Yin had to stop cultivating, hold Yuan Shouyi, and rely on his indomitable perseverance to forcibly suppress the restlessness and riot in his heart!

However, the mana in his body was also filled with a violent aura that destroyed everything, although the power had increased greatly, Xia Yin was trembling, worried that this tyrannical aura would one day lose control of his mana......

But none of these were the reasons why Xia Yin stopped cultivating.

Xia Yin knew that he had no choice, no matter how big the risk was, there was only one way to go dark!

The real reason for leaving the customs is because under the binge eating like jelly beans every day, six or seven kinds of pills have lost their effect!

Xia Yin guessed that either these ordinary pills could no longer meet the needs of cultivation as their cultivation skyrocketed, or that after taking these pills for a long time, the body had become resistant, so that the pills had lost their effectiveness against themselves.

As for the other elixir formulas, they belonged to the elixirs taken by the Zhuji monks, and there were several medicinal materials that had not yet been collected and could not be refined at all.

So Xia Yin had to go out of the customs, planning to get a few new pills, and then continue to refine the pills, cultivate, and improve his strength.

If you want to build a foundation in one fell swoop, Danfang has become the key!

......

Xia Yin came to the medicine field from the foot of the mountain, and saw Youyou busy in the jungle at the edge of the medicine field from a distance, holding a large handful of colorful wildflowers in bloom in his hand.

This year, because the poison of the cold was suppressed, and Xia Yin entrusted Senior Sister Wu Min to buy a lot of supplements to nourish her sister's body, today's Youyou is very different from the thin and weak a year ago!

Not only has he grown taller, but his face is ruddy, and he has also grown some flesh, and he is slim, as if he has changed into a different person.

In a good mood, Yoyo planted flowers around the hut, and often went to the mountains to pick a large number of flowers, and arranged the hut very beautifully......

"Yoyo, brother is here!"

Xia Yin shouted loudly.

Yoyo in the jungle quickly straightened his waist and waved the flowers in his hand at his brother, smiling extremely sweetly, like a butterfly wearing flowers.

"Brother, do you see these beautiful flowers?"

Xia Yin smiled and nodded: "Beauty, it's almost time to catch up with my family!"

You You couldn't help but blush, and then his face darkened: "Alas, it's a pity that no matter how beautiful the flowers are, they will only bloom for a short time, and they will soon wither!"

Xia Yin knew the meaning of his sister's words, and felt as if his heart had been pricked by a needle, but he pretended to smile easily: "Then you can bear to pick them down!"

Yoyo sighed softly: "I also wanted them to open quietly, but brother, even if I don't pick them off, they will wither quickly, so Yoyo wants to collect them together while they are blooming, and arrange these flowers into the most beautiful scenery, so that they will not come to this world in vain!"

Looking at her sister's face hidden in the flowers, Xia Yin fell silent.

If it weren't for the damn cold, this face would be like a flower!

"Yoyo, my brother promises you that he will definitely find a cure for the cold disease!"

Xia Yin said with a firm face.

A trace of sadness flashed in Yoyo's eyes, but a smile quickly appeared.

"Actually, with my brother by my side all these years, Yoyo has been much happier than these flowers!"

Xia Yin was about to speak, but he noticed a figure in the air......

This figure flew rapidly from the direction of Mu Ling Peak, and landed next to the two brothers and sisters in a blink of an eye.

"Senior Brother Xia Yin, I'm actually free today!"

Wu Min looked at Xia Yin and Yoyo with a smile on his face.

"Sister Wu Min!"

Running over happily and hugging each other.

During this year, Xia Yin was busy cultivating, but Wu Min often came to the wooden house to accompany Youyou, and the two of them had become sisters who talked about everything.

"Senior Sister Wu, you always sneak out, aren't you afraid that your master will catch you and punish you for retreat?" Xia Yin laughed and teased.

Wu Min smiled and said: "Every time I come, I say that I ask my grandfather for the way of alchemy, which is very reasonable!"

Xia Yin smiled and said: "This is a good idea, but it is too troublesome for my junior sister, this year, in order to teach me alchemy, my junior sister's cultivation has been delayed!"

Wu Min glanced at Xia Yin, and a touch of red light flew on his face.

"Senior Brother Xia is polite, you should help!"

Xia Yin looked at Wu Min and said solemnly: "Senior sister's kindness is remembered in my heart!"

However, after listening to Xia Yin's words, Wu Min showed a lonely expression on his face, with a hint of resentment.

Xia Yin, who is usually as careful as a hair, didn't notice the change in Wu Min's face this time.

"Senior Sister Wu, it seems that you have been staying at the tenth layer of qi refining for more than two years, right?" Xia Yin suddenly asked.

Wu Min restrained the grievances on his face and nodded slightly: "Yes, my cultivation qualifications are mediocre, and the reason why I can cultivate to the current realm is actually that my grandfather used pills to pile up, but it's a pity that my body has developed resistance, and now taking pills has no effect!"

"Hey, junior sister, you too...... There is such a thing as drug resistance!"

Xia Yin originally wanted to ask, "Do you have this situation too?", but suddenly remembered that he couldn't expose the secret of the elixir of ripening buds, so he quickly changed his words.

Fortunately, Wu Min didn't notice the flaw in his words, and nodded with some emotion: "Yes, if I take too many pills, my body will become resistant, and I can't improve my cultivation by taking pills now!"

Xia Yin couldn't help but feel nervous.

If that's the case, then wouldn't you be ......

"Senior sister, you can let Master Wu refine other pills for you to take!" Xia Yin induced the other party.

Wu Min smiled bitterly and said: "My grandfather naturally thought of this, but I have already taken all the pills taken by Qi refining period cultivators, and those pills that can only be taken by foundation building monks or Jindan monks, because the effect of the medicine is too strong, I can't take it!"

Xia Yin looked incredulous: "It's impossible, your grandfather is an alchemy master, and he can refine at least hundreds of pills, how can he let you stop cultivating!"

Wu Min shook his head slightly: "Senior Brother Xia, you don't know, in today's cultivation realm, because the aura is becoming more and more scarce, many elixirs have become extinct, resulting in many Dan prescriptions losing their effect, and the birth of Danfang requires at least four or five generations of Dan masters to continue to explore, try, improve, and finally complete, and every Dan master will not easily pass on the Dan Fang, so in today's Xiuzhen Realm, even if there is an alchemy master like Grandpa, it is difficult to find a new Dan Fang!"

Xia Yin couldn't help but be completely stunned!

For a long time, because he had been dealing with Master Wu for a long time, and this master did not regard himself as an outsider, it was easy for him to know some Dan prescriptions......

This kind of experience has given me the illusion that Danfang should be an ordinary thing that can be seen everywhere!

"In this way, wouldn't it be very difficult to obtain a new Dan Fang!" Xia Yin asked with some humility.

Wu Min nodded: "Of course, even if the Dan Fang used by the Qi Refining Stage cultivator wants to buy it, it will require thousands of spirit stones, and the appearance of a new Dan Fang will often lead to a scramble!"

"What ......"

Xia Yin suddenly roared and almost jumped up.

Such a violent reaction frightened both Wu Min and Youyou!

At this moment, several figures suddenly appeared in the air, shooting from the direction of Jin Ling Peak......
