In the sky above a valley surrounded by the Fengzhi Forest in the south of Yezhou, dark clouds rolled, lightning and thunder roared, and powerful thunder and lightning broke through the air and hit the valley directly, as if to destroy the golden figure sitting in the valley!

From time to time, a figure would pass outside the valley, there were demon cultivators in the forest, and there were also monks who came to the forest to train, they all came and went in a hurry, because the valley was protected by a formation that they couldn't crack.

"Boss, human cultivation dares to come to our forest to advance the catastrophe, should we take the opportunity... A combined leopard demon made a neck wiping motion against a Mahayana leopard demon.

"Can you break through that formation?" said the Mahayana Leopard Demon angrily.

"This... ”

"Put away all your careful thoughts, in recent years, there have been several powerful cultivators in the forest, and even the predecessors of the Great Demon are not their opponents, you better not provoke them!"

The Mahayana Leopard Demon looked at the direction of the valley with a serious expression, over the years, he had heard that many high-level elixirs guarded by the Great Demon were taken away by the same group of cultivators, and with the power of those big demons in the forest, they didn't investigate it at all, which shows the strength of those people.

A few days later, the thunder and lightning disappeared, the clouds cleared, and then a glow appeared over the valley, and it was not long before it began to rain.

After the gan rain, Mu Ningyi, who exuded a powerful momentum, walked towards the bamboo house in the valley with great energy, and happily said to Ning Xin, who was standing outside the courtyard and watching him, "Sister, I have successfully advanced to Mahayana!"

"The breath is strong and calm, not bad!" Ning Xin looked Mu Ningyi up and down, and nodded with satisfaction, "But I still have to stabilize my cultivation after that." ”

"Well, I know, sister, thank you!" He understood that if it weren't for the elixir baths his sister had soaked him, his cultivation would not have improved so quickly.

"You and my brother still need to be polite, you relax now, I'll investigate your knowledge!"

"Hmm!"

As soon as the divine consciousness entered the sea of Ning Yi's consciousness, Ning Xin found that the area of halo emitted by the auspicious cloud mark on his primordial spirit had become a little larger!

"Sister, how is it?"

"Well, the bone-shaping medicated bath works well, we have to keep it up!"

Thinking of the pain that was worse than death, Mu Ningyi shuddered, "Sister, can you change to another medicated bath? It's so torturous!"

"I can stimulate the power of the bloodline, and I have paid a lot of price!"

"Oh, I see!" Mu Ning replied in a huff.

Looking at her younger brother with a sad face, Ning Xin smiled and shook her head, "Don't worry, I have improved the bone shaping medicinal bath, it shouldn't be as painful as before!"

"Really?" Mu Ningyi looked happy.

"Hmm!" Shennong's Treasure Book is indeed a holy treasure in medicine, after mastering the content inside, when refining the elixir and potions, she can quickly optimize the configuration of the elixir and get rid of the drawbacks inside.

Take the bone-shaping medicinal bath as an example, before she could only make some collocations according to the medicinal properties of the elixir, so that the effect of the medicinal bath was more significant, and it could not eliminate some of the discomfort caused by the medicinal bath.

Now, after mastering the Shennong Treasure Book, the medicinal bath she refined not only increased the medicinal effect several times, but also eliminated the discomfort caused by her to the greatest extent!

"Sister, when do you think I will be able to stimulate the power of the bloodline?"

"It depends on chance!" Although she refined a bone-shaping medicinal bath for Ning Yi, every time he fell unconscious, she took him into the space to invade the Immortal Pool and the Chaos Heavenly Water Pool, but it was really hard to say when it would be able to stimulate his Protoss bloodline!

"That means I'm going to have to take a bone medicated bath from now on!"

"You can be content, others can't soak if they want to!"

In the following decades, in addition to going to Tianzhi City to visit his master Ye Frame, Ning Xin took Ning Yi and the three demons to constantly shuttle around Yezhou, while training, while looking for a way to remove the Yin poison of the Nine Turns of Heaven in the body.

During the training, Ning Xin found that many monks in the remote immortal city were unable to heal and could not afford to buy healing pills after being injured, so they could only endure the pain and torture of illness, and her heart was touched.

After that, every time she passed through some remote cultivation places, when she was about to leave, Ning Xin would sit for the local monks for free for three days, and sell some pills that were commonly used by the monks and could not afford to buy them at low prices.

Because of Ning Xin's superb medical skills, she has cured many terminally ill monks, and the quality of the pills sold is good and affordable, which has attracted the praise of the monks and the monks.

In a remote town in the west of Yezhou, many monks hurriedly ran towards the city gate.

"Hurry up, hurry up, the Divine Doctor Fairy is sitting at the gate of the city!" I don't know when everyone called the Divine Doctor Fairy because they didn't know Ning Xin's identity!

At this time, there was already a long queue at the city gate, Ning Xin, who was wearing a veil, was sitting at a table seriously diagnosing the monk, Mu Ningyi was standing behind her, listening to her orders, and Xiaolong was taking the little black bear to maintain the order of the queue!

"Ning Yi, give this fellow Daoist a bottle of Blood Pill!" After Ning Xin finished speaking, Mu Ningyi immediately took out a bottle of pill and handed it to the old man in front of him.

"Divine Doctor Fairy, does this Blood Pill really only need a hundred low-grade spirit crystals?" The old man looked at the bottle of yellow-grade top-grade pill in his hand with some excitement.

"Well, as long as you finish taking this bottle of elixir, the injuries on your body should be healed!"

"Thank you, Divine Doctor Fairy, thank you Divine Doctor Fairy!" the old man said gratefully.

In a remote place like theirs, there are not many alchemists, so the pills are sold very expensive, and most of the monks here are casual cultivators, and they don't have any net worth, so they can't afford to buy expensive pills at all, so they can only survive if they are injured.

After the old man gave the spirit crystal, he did not leave, but walked to the side to observe Ning Xin and the others, looking a little hesitant!

At the end of the evening, Mu Ningyi saw that the old man was still standing aside, so he said, "Fellow Daoist, do you have anything else?"

As if he had made up his mind, the old man quickly came to the front of Ning Xin and Ning Yi, "Divine Doctor Fairy, can I invite you to our village?"

"Are there any other injuries in your family?" Ning Xin asked with a smile, this old man had been observing them all day!

"No, it's from our village!"

"A village?" Ning Xin and Ning Yi were both a little surprised.

"Well, a month ago, the people in our village suddenly got a strange disease, except for me and a few others who went into the city to sell elixirs!

"What strange disease they have, can you describe it to me?"

"Severe pain all over my body, rapid weight loss... ”

With the old man's description, Ning Xin and Ning Yi's expressions fluctuated rapidly, how could this symptom be somewhat similar to those poisoned monks in Wang Zhou before?

"Where have they been before, and what strange things have they encountered?"

"Except for the people in our village, who go into the mountains behind the village to pick elixirs, they rarely go out at other times, and I haven't heard them say that they have encountered anything strange. ”

"Fellow Daoist, you go back first, and when I finish the consultation, I will go to your village with you to have a look!"

"Thank you, Divine Doctor Fairy, thank you!"
