Some time ago, Fan Yu also asked Qin Xia for a lot of medicinal materials, at that time, Qin Xia thought that this guy was crazy, he actually wanted so many medicinal materials, and now he knew that he was really doing the experiment of refining the Blood Source Pill, and after a period of practice, he finally succeeded.

Over the past few days, Fan Yu has met two like-minded classmates, named Li Xiaoming and Lin Huari.

That night, after Fan Yu had dinner with Li Xiaoming and Lin Huari, he went back to his home to retreat and meditate.

These days, in order to improve his cultivation as soon as possible, Fan Yu often retreats and cultivates. During Fan Yu's cultivation, Yuluo and Little White Tiger acted as his "bodyguards" and prevented him from receiving any interference from the outside world.

Soon, two days passed, and after Fan Yu came out, he asked Lin Huari to bring a large number of medicinal materials, and he wanted to refine the four pins of pills.

It turned out that during the retreat, Fan Yu recalled the secret recipes for refining pills sealed in his sea of knowledge, and then combined with the knowledge he learned from Qin Xia, his understanding of Dan Dao reached a new height, and he finally had confidence in refining the four pins of pills.

"Lizhi Flower, Seven-Leaf Star, Tiger Heart Grass, Spirit Dragon Fruit, plus three hundred years of iceberg ice lotus and Haisha Golden ......" Fan Yu looked at a large number of precious medicinal materials placed in front of him, and his eyes unconsciously released brilliance.

"Fan Yu, these precious medicinal materials can only be purchased with a lot of spars, you have to refine them carefully, otherwise you will waste this material, and it is not fun." Lin Huari said to Fan Yu unconsciously and a little distressed.

"Lin Huari, do you still doubt my strength" Fan Yu smiled unconsciously, and said quite confidently: "You can rest assured, with my current strength, refining this four-grade elixir is like taking it at hand." ”

"Yes, a few days ago, Qin Xia also publicly said that according to your current strength, you can refine a third-grade pill at most, and to refine these fourth-grade pills, you have to cultivate for at least 2 months. Lin Huari said very seriously.

After a pause, Lin Huari reminded Fan Yudao again. "So, you have to be careful, and if you're not sure, you might as well give up. After all, these medicinal materials are so expensive, if you are not careful, you will waste a lot of money. ”

"Eh, why are you so unconfident in me? As the so-called Shibei should be impressed by the three days, I'm not afraid to tell you that my strength has increased greatly now, and refining the four-grade pill is not an easy thing for me? Therefore, don't worry about it. Fan Yu said with a smile.

"In that case, then I will put these medicinal herbs in place, you can watch and do it. Also, it cost me 250 carved crystals to buy these medicinal materials, and you have to remember to return them to me tomorrow. Bye. Lin Huari put those medicinal materials in front of Fan Yu and left very unhappily.

Looking at Lin Huari, who was angry because he didn't believe in himself, Fan Yu didn't feel gloomy, and said in his heart: "Why don't you all believe me? ”

After Lin Huari left, Fan Yu looked at the large pile of medicinal materials in a daze: "With so many medicinal materials, what pill should I refine?"

Fan Yu then searched for the best compatible recipe from Zhihai, and finally chose a recipe for refining the Yuan Realm Pill.

Then, Fan Yu took out the Qianyang One Qi Dan Furnace and began to prepare to refine the Yuan Realm Dan.

The elixir that Fan Yu wanted to refine was called the Yuan Realm Pill, which was an elixir used to Pei Yuan to break through the martial arts realm, and its rank reached the fourth grade.

It can be said that in this Xingwu Continent, the four-grade pill is already very expensive, and the selling price of one can reach at least 1,000 spars.

If Fan Yu can successfully refine this four-grade Yuanjing Pill this time, he will be developed in the future, not only can he quickly raise the surgery fee that Yuluo needs, but from now on, he can make a fortune by refining this four-grade pill.

Of course, Fan Yu knew the importance of refining the pill this time, if he failed, not only would he lose 1,000 spars, but his reputation would also be damaged.

If he succeeds, then he will be able to live a comfortable life in the future.

The refining steps of the four pins of pills are very cumbersome and complicated, if you are not careful, you will fail to refine, and the consequences will be to waste a lot of good medicinal materials, or it will lead to the explosion of the Dan furnace and cause casualties to the alchemists.

Because the consequences would be very serious, many people who refined the pill did not dare to refine the four-grade pill easily, and in Nantian City, there were not enough people who could and dared to refine the four-grade pill, it was really rare.

Fan Yu carefully selected the medicinal materials needed to refine the Yuan Realm Pill, and placed those medicinal materials according to the refining procedure, and then put those medicinal materials into the alchemy furnace one by one in order.

After all the materials were placed, Fan Yu concentrated his energy, slowly summoned the Purple Mansion Heavenly Fire, and then poured it into the alchemy furnace to refine those materials.

........................

However, it was said that 300 meters away from Fan Yu's refining of the pill, suddenly two old men were running towards this side quickly, and one of the two was a well-known senior teacher in the academy, his name was Lu Qing.

This Lu Qing is very famous in the academy, he is not only a senior teacher, but also a well-known four-grade alchemist in the academy, he is really a respected and respected old teacher.

Why is Lu Qing running so hurriedly now?

It turned out that it was because Lin Huari had accidentally told Lu Qing the news that Fan Yu was going to refine the four-grade pill just now, so he was so angry that he ran over in a hurry like fighting a fire and saving people.

"Uh, Qin Xia, you are really, you can actually rest assured that you will hand over a large number of medicinal materials to that Fan Yu student to refine the pill, and it is a fourth-grade pill, do you know? If you don't get it, something will happen, do you know it? Hey, now I hope that Fan Yu's kid hasn't used those materials to refine the pill. Old Teacher Lu Qing said in a chattering voice while hurrying away.

It turned out that Lu Qing was just thinking about opening the furnace to refine the four-grade Ziyuan Dan, but when he arrived at the medicinal material storehouse, he was missing the very important rare material Spirit Dragon Fruit. When Lu Qing asked the old man who was guarding the medicinal herb storehouse, he found out that this rare ingredient spirit dragon fruit had been taken away by Lin Huari.

When Lu Qing hurriedly found Lin Huari, he knew that the flavor of the dragon fruit had been given to that Fan Yu by him, and it was given to him for refining the Four Pins Pill.

After listening to Lin Huari's words, Lu Qing was surprised.

It turned out that at the Dan Dao Theory Forum held a few days ago, although Fan Yu showed a very high level of Dan Dao, Lu Qing also sighed.

However, the debates held in the forum are only theoretical knowledge, and the key point is that there is no practical support.

And this Fan Yu, he came to the academy to learn Dan Dao knowledge for less than three months, and the practice is really poor. Refining elixir is expensive in practice, and relying on theory alone is often just talk on paper, and it is easy to make mistakes.

What's more, this is a fourth-grade elixir, if Fan Yu makes a little mistake in the refining process, it will cause the Dan furnace to explode and it will kill people.

Therefore, as a senior Lu Qing with rich experience in refining the Four Rank Pills, when he knew about this matter, could he not be in a hurry?

"I said Teacher Lu, the ministry is refining the four-grade pill, is it worth your old man to be so flustered, as if he was in a hurry like a dead old man, is it worth it? Besides, although Fan Yu's kid has not been in the academy for a long time, his Dan Dao knowledge and talent are well known to everyone, so you don't have to worry about him. Lin Huari smiled disapprerovingly, and then said.

Because, Lin Huari still has some confidence in Fan Yudandao's level.

"Eh, this is a big matter of human life, can I not be in a hurry?" Lu Qing is a person with a strong sense of responsibility, so no matter how Lin Huari explains, he is still not very relieved about Fan Yu.

After Lu Qing said this, he immediately activated his true qi, and his speed immediately increased a lot, just like the cannonball that came out of the hall, he ran out of dozens of meters at once, and hurriedly rushed towards the place where Fan Yu was refining the pill.

Lin Huari shook his head, there was no choice but to follow behind Lu Qing unhurriedly.

In less than half a minute, Lu Qing and Lin Huari rushed to the place where Fan Yu was refining the pill.

"Boom" ......

Who knows, at this time, but a loud bang was heard.

Immediately afterward, I saw that a large purple pillar of fire rose above the place where Fan Yu was refining the pill, and it was like a big fireball blooming in the wind, which was very beautiful.

Then, Dan saw that in the firelight, a few golden fruits fell into the fireball, and in an instant, they turned into drops of medicinal liquid and fell into the alchemy furnace.

"Purple Mansion Heavenly Fire!"

Lin Huari and Lu Qing were so frightened by this scene that they stopped, and when they saw the large brilliant purple pillar of fire rising into the sky, they unconsciously glanced at each other, revealing their eyes full of surprise.

Because they knew that at this time, Fan Yu's kid had already begun refining the elixir.

The Purple Mansion Heavenly Fire is a necessary condition for refining that high-grade Purple Mansion grade taste pill.

It is said that the people who have this kind of Zifu Heavenly Fire are very magical and rare, and there are not enough people in the entire Xingwu Continent who can have this kind of Innate Zifu Heavenly Fire, which shows that it is extremely rare.

And the reason why Fan Yu was able to possess the Purple Mansion Heavenly Fire was entirely because of the knowledge of the sea in his previous life.

One night just three days ago, Fan Yu took advantage of the dead of night to sit on the bed and practice Dan Dao, with his unintentional thought, suddenly a trace of purple fireworks appeared in the center of his eyebrows, and then he led it to the tips of his fingers, but saw that the purple flame became more and more vigorous, and then it turned into a purple flame that could dance, and the gorgeous purple was shining in the room.

This Purple Mansion Heavenly Fire is the most gorgeous purple fireworks that Fan Yu obtained after a lot of hard work in collecting countless different fires in heaven and earth in his previous life, and then through spiritual refining.

It was a heavy weapon for refining pills, and with him, Fan Yu was able to dominate in the previous life, refining many high-grade pills, and becoming a veritable high-level rune array master.

Then, after more than 3,000 years of warm cultivation, the Purple Mansion Heavenly Fire became purer, purple, and more gorgeous, and deeply imprinted in Fan Yu's sea of knowledge.

"It's really good, I didn't expect that after I was reincarnated, this precious Purple Mansion Heavenly Fire was brought with me, it seems that God is good to my brother." Okay, my brother will be developed in the future, and he will cultivate into a high-level rune formation master, and he will be dominating in this Star Martial Continent. Fan Yu felt a little excited in his heart.

After knowing that he had the Purple Mansion Heavenly Fire, Fan Yu continued to cultivate and strengthen it, and after two months of strengthening, now his Purple Mansion Heavenly Fire has finally reached the point where he can send and receive it freely, and he can refine the pill with the transfer.

Now, in the Purple Mansion Tianhuo has finally helped Fan Yu a lot, and he also knows that if it weren't for the help of this Purple Mansion Tianhuo today, he wouldn't be able to refine this four-grade Yuan Realm Pill anyway.

"I didn't expect that Fan Yu's kid to move so quickly, not only a few minutes after I left here, he made all the preparations and started refining the pill, haha. Lin Huari smiled happily when he saw this scene.

"Okay, since that kid Fan Yu has already started refining pills, it's better for us not to disturb him, otherwise he will be distracted, and it will be easy to make mistakes. Let's wait here for a while and then go to Fan Yu's place. "Lu Qing is a person who is very experienced in refining the four-grade pill, if there is interference from the outside world in the process of refining, it will distract the refiner, and lead to an accident, the Dan furnace will burst at the lightest, and the Dan furnace will explode at the worst, which will kill the person refining the pill, then the consequences will be unpredictable.

Who knows, for Fan Yu, refining these four pins of pills is just a trivial matter, and he doesn't need to pay full attention at all, but seeing that he is reciting his hand and printing the Purple Mansion Heavenly Fire, while introducing the refined pill liquid into the Nadan furnace, he looks very skillful and relaxed.
