Since the end of the Lantern Festival, Gu Xiaoxian has gone out to collect medicine every day, and every time she picks medicine, she will also bring pastries to visit Dai Lao. At first, she only went to visit the old man's injury, after all, it was also because she had to be reckless.

But in fact, Dai Lao's injury has long been healed, I have to say that the medicine in the medical hospital is indeed magical, just like Gu Xiaoxian said, just one sticker, Dai Lao's back injury has already healed. But Gu Xiaoxian still runs here every day, according to her, in order to apologize and bring more delicious food to Dai Lao.

After a long time, it has become a habit. Maybe it's because every time she sees this kind old man, Gu Xiaoxian thinks of her grandfather, so she can't help but want to be close.

Every time I come to the cabin, I always have the illusion of being with my grandfather. Gu Xiaoxian has been closest to her grandfather since she was a child, and she also respects her grandfather the most in the family.

But when her grandfather passed away early, Gu Xiaoxian always regretted that she had not fulfilled her filial piety to him, so every time she saw Dai Lao's happy appearance, Gu Xiaoxian felt satisfied from the bottom of her heart.

She doesn't have many friends in Star City, so she also cherishes everyone who is good to her.

One day, Gu Xiaoxian, as usual, took pastries to visit Dai Lao, but the old man did not rush to eat pastries this time, but handed Gu Xiaoxian a small bottle and said, "Girl, this is for you, it is good for you." ”

"What is this?" Gu Xiaoxian said and opened the bottle, and suddenly the medicinal fragrance was fragrant, and after Gu Xiaoxian smelled the smell, she felt a lot lighter all over her body.

"Nature is a good thing. Dai Lao replied with a smile.

Gu Xiaoxian poured out the contents of the bottle again, and inside was a black pill, but this pill was obviously full of spiritual power, and there were runes emerging on it.

Gu Xiaoxian said in disbelief: "How can it look a bit like the elixir practiced by the elders of the medical dean." "Gu Xiaoxian has also been in the medical academy for so long, so naturally he has seen the elixir, which is a bit similar to this, but there seems to be no such rune on the elixir refined by the elders.

"You girl knows the goods. Dai Lao stroked his white beard and looked at Gu Xiaoxian with a smile.

"Bearded grandpa, how can you have an elixir?" Gu Xiaoxian looked at Dai Lao with some suspicion.

"Ahem~coughahem~ My father was a physician, and he once taught me some medical skills, and this elixir was left by my father. Anyway, the old man doesn't have a spiritual root, so he doesn't need this thing, and if you look at this girl, it will be cheaper for you. Dai Lao said with an indifferent look.

However, as an apprentice of the medical academy, Gu Xiaoxian knew that not to look at what Dai Lao said was so easy, but in fact, every medicine was an extremely precious thing.

Even if it's just a low-grade pill, it's extremely complicated to refine, and it can be sold for a high price when you take it out.

What's more, Gu Xiaoxian could see that the grade of the pill in front of her was not low, at least it was a top-grade pill. Because Gu Xiaoxian had seen the appearance of a medium-grade elixir, there was no such a strong medicinal fragrance, and there was no such rune. As for the best elixir, she couldn't even think of it, that kind of thing was too precious, and it was almost difficult to refine it successfully.

Now that Dai Lao casually threw Gu Xiaoxian a high-grade elixir, Gu Xiaoxian was simply flattered. I didn't expect such a good thing to fall on her head. You must know that one high-grade pill can be worth dozens of medium-grade pills and hundreds of lower-grade pills.

An apprentice like her, if he had the chance, he would be extremely lucky to be able to get a low-grade elixir, and he would be able to save a lot of cultivation time.

Even those genius disciples often had the opportunity to take pills, but most of them were only low-grade or medium-grade pills.

And now, what appeared in front of her was a top-grade elixir, Dai Lao was really a big deal, his father should be a very powerful alchemist, otherwise there would not be an elixir of this quality.

"Ahem, girl, it's time to come back to your senses. Dai Lao saw that Gu Xiaoxian looked at the pill in a daze and didn't speak, so he reminded with a smile.

"Grandpa, you're so nice!" Gu Xiaoxian happily held Dai Lao's hand and sprinkled coquettishly. She was also not polite to Dai Lao, after all, this was exactly what she needed.

"You girl, just bring more delicious food to the old man in the future. Dai Lao looked at Gu Xiaoxian and said dotingly. In fact, not only Gu Xiaoxian has a sense of closeness to him, but he also loves Gu Xiaoxian very much.

"Hehe, promise to complete the task!" Gu Xiaoxian replied with a grin.

"Okay, okay, you go back quickly, you have refined the pill earlier. Bring more good food next time you come. ”

Gu Xiaoxian nodded heavily, and accompanied Dai Lao for a while, and then left early, she really wanted to know the effect of this elixir, after all, this was the first time she had obtained such a thing as an elixir.

Therefore, as soon as Gu Xiaoxian returned to the medical institute, he went straight to the Qi training room of Haiyun Pavilion, and then found a quiet room, sat down cross-legged, and after his breath was slow and his mind was settled, he turned his hand and swallowed the pill given by Dai Lao, and then began to refine it.

It is worthy of being a top-grade elixir, under the powerful and amazing power of the medicine, the aura in the body instantly soared, like a loose horse scurrying in the dantian.

This sudden appearance of powerful aura seemed to be a little beyond Gu Xiaoxian's tolerance, a sharp pain came, Gu Xiaoxian broke out in a cold sweat, and he couldn't care about anything else at the moment, so he had to grit his teeth and slowly run the Ice Heart Technique, trying to guide the aura in the dantian into the meridian circulation.

In this way, after a few big weeks, Gu Xiaoxian actually directly broke through the middle stage of Qi training and entered the late stage of Qi training.

However, most of the aura transformed by the pill remained in the dantian, although Gu Xiaoxian had gradually become accustomed to the pain caused by this aura impacting the dantian, but with such a huge aura staying in the dantian, she could only continue to run the Ice Heart Technique.

With such a huge amount of spiritual power, she even began to wonder if the elixir that Dai Lao gave her would be the best elixir, but soon, she forcibly expelled this absurd idea from her mind.

I don't know how long it took, Gu Xiaoxian felt that the aura in her body had entered a saturated state, and she could no longer transform. A flash of inspiration flashed in her mind, and she remembered that Shen Lao had mentioned that this seemed to be about to impact the state of the foundation building period.

Gu Xiaoxian no longer hesitated at the moment, and according to the method of foundation building that Shen Lao said, he took out a trace of origin spiritual power and slowly guided the spiritual energy in the dantian to begin to impact and broaden the meridians, allowing more spiritual energy to pour in.

When the huge aura hit the meridians, Gu Xiaoxian felt a sharp pain coming, and she could almost clearly hear the sound of the meridians in her body breaking inch by inch, but then they were connected under the effect of the pill, and so on.

Gu Xiaoxian thought that the pain of the aura impacting the dantian before was already the limit, but he didn't think that the pain of the broken meridians of the whole body was even more unbearable.

She didn't know if it was like this for every monk to advance to the foundation building stage, or was it just her because of the reason for the cross-level promotion with the help of medicinal power?

However, at this moment, Gu Xiaoxian didn't have time to think about this, the broken tendons and veins in her body and the spiritual power that kept rampage made Gu Xiaoxian cry bitter.

Even so, Gu Xiaoxian still gritted her teeth and insisted, you must know that the way of cultivating immortals is to go against the sky, if she can't even bear this pain, how will she go down this road in the future.

As time passed, Gu Xiaoxian's meridians continued to expand, and the aura in his body became more and more condensed, until the original gas-like aura condensed into a light blue liquid, which gradually converged in the dantian.

The original rampaging aura in the body was all gone, and in its place was a small pale blue lake in the dantian. The lake water flowed along the meridians to all parts of the body, and Gu Xiaoxian only felt that his whole body was incomparably over, and he had a feeling of fluttering immortals.

It was only at this time that Gu Xiaoxian slowly opened her eyes, and she knew that this was the success of foundation building.

Breaking through two small realms in a row, and directly reaching the level of the second-grade foundation building period after crossing the late stage of qi refining, all of this is like a dream.

Originally, it was difficult to reach the foundation building period from the Qi Refining Period, and many people were blocked from this step in the late stage of Qi Refining throughout their lives. And Gu Xiaoxian actually broke through this bottleneck in one fell swoop, I don't know if she is so talented, or if Dai Lao's elixir really has such a miraculous effect.

When Gu Xiaoxian reached the foundation building period, she immediately experienced a completely different feeling from the past, and her five senses seemed to have suddenly been raised to an incredible realm.

Everything in the eyes suddenly became so bright and clear, and even some very subtle things were suddenly magnified, and the details were visible. Her ears had become so sensitive that whenever she wanted to hear, countless sounds she had never heard before poured into her ears, as if they were ringing in her ears. In addition, Gu Xiaoxian knew that her sense of smell was also very different from before, as long as she wanted to smell, people walking dozens of miles away could be detected.

Gu Xiaoxian was surprised and delighted, Shen Lao and Qin Yuanke had never told her that after her cultivation reached the foundation building period, there would be such a big change. Gu Xiaoxian even felt that even if she didn't sleep for a month, she wouldn't feel sleepy.

Gu Xiaoxian was able to check all the big and small affairs outside the house only in the qi refining room, and this feeling of being able to control everything really made Gu Xiaoxian overjoyed.

She, Gu Xiaoxian, is also a monk in the second-grade foundation building period! This can be regarded as truly stepping into the world of cultivation......
