Fang Cun has memorized the Dan Sutra by merit, Dan Dao talent is naturally not bad, just learning Dan, it is not a day's work, no matter how good the talent is, it is just to let yourself learn fast, if you want to achieve it overnight, it is not enough to learn alone, it may be possible to find a cliff jump!

Therefore, if he wanted to refine the Dan Gu, he could only find a helper.

Looking around, who is more suitable?

Old Mr. Qu should be the most suitable, but this old gentleman is too upright, Fang Cun didn't dare to ask him about alchemy Gu, for fear that if he chatted, the conversation would collapse, so he thought about it, and the most suitable one was Qu Su'er Qu's little sister.

Fortunately, Mr. Qu has been busy refining Bao Dan recently, and he has plenty of time, and Little Sister Qu is also very obedient and sensible, let her do whatever she wants, since Fang Cun decided to ask for alchemy Dan Gu, she began to participate in research and try, it is said that she saw how to refine Dan Gu when she was a child, but after leaving home, Mr. Qu regarded Dan Gu as an evil thing, did not teach, and did not let her touch it, she had not practiced it for many years.

At first, Fang Cun was worried that the time was too long, and she couldn't remember, but later she found that she thought too much.

When talking about the Dan Sutra, the little sister of the Qu family looked weak, how to say it when she was refining the Dan......

The Dan furnace that was originally bought for Mr. Qu to refine the Bao Dan was not used, and at this time it was just for the little sister of the Qu family to use, so Fang Cun brought the fox girl Xiao Qingling and Xiao Qingliu both, both of whom ran over to see with excitement on their faces, and then looked at the little girl of the Qu family with a nervous face, and threw the elixir into the Dan furnace, as if she was afraid of making a mistake in every step, refining and throwing a few times, and nervously looking at the notes.

After refining for half an hour like a great enemy, she slowly ceased fire under the gaze of Fang Cun, Little Fox Girl, and Little Aoyagi, and then nervously opened a porone, and black smoke slowly drifted out from the Dan furnace......

"How so? How can it be black?"

The little girl of the Qu family was slightly stunned, her face was puzzled, and she hurriedly went to turn over the Danjing.

"It really failed......

Fang Cun, Little Fox Girl, and Little Aoyagi shook their heads helplessly at the same time, which was not unexpected.

After all, it's been so long......

"It shouldn't be......"

The little girl of the Qu family flipped through the Danjing for a long time, and seemed to be a little impatient: "The steps are right......"

Fang Cun cleared his throat, ready to comfort him.

Then I saw that the little sister of the Qu family didn't find what the problem was for a long time, and slapped her angry palm on the Dan furnace: "What's wrong?"

Boom!

The high-grade Dan furnace forged by the black iron mixed with red copper has been photographed with a clear slap print.

"Hoo ......"

A wisp of purple gas erupted from the Nadan furnace.

The little girl of the Qu family was a little surprised, and turned her head shyly to Fang Cun and said, "It's been refined!"

"This ......"

Fang Cun's neck was a little stiff, he eased his nerves, got up politely, and saluted: "Yes...... There's a Fairy Lao......"

In the next few days, when the little girl of the Qu family was alchemizing, Fang Cun, the little fox girl and the three of Xiao Qingliu were all very cooperative, what to give, serve tea and pour water, and the old man and Mrs. Fang saw that their son was busy running around every day, saying that he was alchemy, and felt very relieved.

Then after a visit, he never came again, and made the courtyard a forbidden place.

But in any case, the first furnace of Dan was always slapped out by the little girl of the Qu family, and then gradually refined a few furnaces, and they were all successful, but on the copper furnace, there were several more slap prints, which always gave people a somewhat pitiful look......

......

......

And after the Mu Dan is refined, the Gu refining will begin.

Now the cave under the rockery of Fangfu is full of bottles and jars, and even some glass jars, grass pattern boxes, dazzling, and very strange, these things, there are not only the "Catch Adulterer Gu" that helped him find Mr. Lanshuang before, but also many strange "Drill Heart Worm", "Soul Devouring Gu", "Golden Thread Snake Egg", "Grass Spirit Firefly" and other strange insects and flowers.

All the things were bought by Fang Cun on the night square, and he memorized the "Spirit Sutra" with merit, and he also read the Fang Cun of the twelve notes of the witch Gu taught by Lingxiu, and he already had a very high talent and vision in these insect Gu paths.

Although there are many fake things on the night shop, there are also some real things, and the most important thing is that after the death of Lingxiu Jiaoxi, the strange insects and Gu children she left behind were all sealed by the academy, or destroyed, or secretly sold. Some of them were bought back by Fang Cun, and among them, Fang Cun valued the most was a Gu worm called "Drill Heart Worm"!

This insect ranks seventh among the twelve Gu worms that Lingxiu has spent most of his life studying, it is an extremely vicious witch Gu, once it is planted on a person's body, it can be urged by its own mind, and it will burrow into the meridians and spinal cord of people, eroding people's souls, confusing people's minds, and even being controlled arbitrarily by people refining Gu, it is really a powerful witch Gu!

"Childe...... Childe, is this the kind of Gu you want to refine?"

After Sister Qu Su'er saw the Gu worm that Fang Cun had taken, she looked at it with some curiosity.

Fang Cun smiled: "Yes, what does my sister think of this Gu?"

Qu Su'er said a little embarrassed: "It's good, it's just ...... Not very useful......"

Fang Cun: "!?"

Qu Su'er saw Fang Cun's expression, and hurriedly explained in a low voice: "When I was a child, I heard my uncle say that this kind of Gu worm is arranged according to the four grades of spirit, treasure, god, and immortal in the world, this Gu should be ranked on the top grade of the spirit level, although it is not bad, but the weakness is also very obvious, the heart worm is a powerful Gu worm, but the vitality is too weak, it is easy to cultivate into a profound person to use mana to dissolve, even if it is not dissolved, if it is sealed for too long, or planted on the bad person for too long, if it is not awakened, it will slowly die by itself......

"Spirits, Treasures, Gods, Immortals......"

Fang Cun nodded slightly, and pondered: "No wonder it is only ranked seventh in Mr. Lingxiu's notes......"

With a thought in his heart, he smiled and said, "Is there no Gu in the world that cannot be solved?"

Qu Su'er shook her head lightly and said, "No, my uncle said that there was, but my grandfather argued with him, saying that although this Dan Gu is vicious, there are just as many solutions, and the insoluble strange Gu rumored in the world cannot exist at all......"

"As long as there is a refining method, there is a solution!"

"At the beginning, they also fought the Fa, my uncle refined seventeen kinds of Gu, planted them on himself, and asked grandpa to solve them, saying that if you can't solve them, let you die a son, but it only took grandpa one day to solve all the seventeen kinds of Gu on his body......"

Fang Cun was stunned when he heard this: "And then?"

Qu Su'er said: "Then grandpa fried all the Gu worms that my uncle refined, and I ate two of them, and since then, my uncle ran away from home, saying that he was going to southern Xinjiang to find the legendary immortal Gu, and he had to let grandpa die a son to finish it......"

Fang Cun: "...... Alas!"

After calming down his emotions for a while, he asked softly again, "What kind of methods are there in the world to solve Gu?"

The little girl of the Qu family said: "The method of refining Gu is ever-changing, and the method of solving Gu is also ever-changing, although grandpa has not taught me the method of alchemy Gu, but the method of solving Gu has told me a lot, he said, all changes are inseparable from its sect, if you want to solve Gu, you need to understand the original intention of the Gu refining person, one seeks control, and sends and receives from the heart, otherwise this Gu will get out of control and become poison." Both are also about the cost......"

"Just like you said, this kind of Gu worm, if you want to control it, you need to use your own innate qi to nourish it when refining, so that you can be tied with one thought, send and receive your heart, and deceive people into eating it, you can harm people, but refining this way, there are two problems, one is to greatly damage your own innate qi, if you don't nourish it with enough innate qi, this Gu worm is connected to the mind of the person refining Gu, as long as the other party's innate qi is strong, it is impossible for you to try to awaken the Gu worm in the other party's body, but if you use too much innate qi to nourish Gu, you will hurt the original ......"

"Second, even if you don't hesitate to hurt your origin and raise Gu with a large amount of innate qi, if the other party's mana is stronger than you, you can also suppress this Gu and forcibly isolate your divine will, and casually, you can refine this Gu worm......"

“......”

“......”

Hearing this, Fang Cun couldn't help but be stunned: "So, the strength of the Gu worm is related to the innate qi?"

The girl of the Qu family nodded lightly: "That's the case, Gu worms grow through innate qi, the stronger the innate qi of a Gu refiner, the higher the quality of Gu worms, the less easy it is to be isolated from divine thoughts, and the more innate qi that Gu refiners feed, the stronger the power of Gu worms, and the more difficult it is to be refined, so many Gu refiners will pick disciples with strong innate qi to be their successors......

Before she could finish speaking, Fang Cun stood up with a smile on his face.

Qu Su'er, who was telling Fang Cun about the way of Gu refining, was stunned when she saw Fang Cun's smile.

His face became redder and redder, and his voice became more and more low: "Childe...... What do you think?"

Fang Cun said with a smile: "I'm thinking, if when refining Gu, you can feed it the strongest innate qi, and keep feeding it innate qi until you are full, then, what will the Gu worm that is refined in this way look like?"

Qu Su'er listened to it, stayed for a while, and said, "That's impossible......"

"Haha......"

Fang Cun stretched out his sleeves and smiled, took the Gu worm back, looked at the Qu family girl seriously and said, "If you have a dream, nothing is impossible!"

......

......

Drilled Heart Worm Gu, Mo said that in the eyes of the Qu family's sister, even in Mr. Lingxiu's notes, it is only ranked seventh, so strictly speaking, it is indeed not a powerful Gu, and it can even be evaluated like this, it can only be used to control some people whose cultivation is lower than their own, and it can only be controlled for a short time, and the evaluation of the upper level of spiritual products is very sincere for it......

But there was a saying before Lingxiu taught that he was right.

Her talent in the "Spirit Sutra" is really too much higher than her!
