In the following days, Xu Fan stayed in Xu Fu's alchemy room every day, learning alchemy with Xu Fu, under Xu Fu's guidance, Xu Fan's alchemy made great progress, and within a few days, Xu Fan could easily refine some pills.

Then, the alchemy room also directly became Xu Fan's territory, and Xu Fu became Xu Fan's assistant instead.

Responsible for the delivery of medicinal herbs each time.

With the release of the Ghost Pill in a furnace, Xu Fan's alchemy (alchemy) is also making rapid progress, and then refining the True Pill, Mixed Yuan Pill and Pei Yuan Pill.

At the beginning, Xu Fan sometimes failed, and then he didn't make a mistake at all, and every time he came out of the pill, it was full of ten, or even eleven or twelve pills, and it was possible to overcomplete the task.

Then there is the refining of the Juxian Pill, this elixir is extremely difficult to refine, it is the most difficult pill to refine among all the elixirs, but Xu Fan's control of internal force is extremely good, and with Xu Fu's professor who spares no effort, Xu Fan has far surpassed Xu Fan in terms of alchemy.

This is also like Xu Fu sighed, no wonder Xu Fan can become the third protector of the Yin and Yang family in less than five years, it is not unreasonable.

The Yin and Yang family spent a lot of effort to find the three medicinal materials of the Gathering Immortal Pill, and in Xu Fan's hands, they turned into twenty-five Gathering Immortal Pills.

Except for the first two refining, there was a slight accident, and he failed to refine a perfect furnace of Gathering Immortal Pill, and the third furnace Xu Fan directly exceeded the task and refined eleven Gathering Immortal Pills, which made Xu Fu speechless for a while.

Ju Xian Dan is the most precious pill for the Yin and Yang family to cultivate, and it is also the most difficult pill to be rewarded, because its refining is too difficult, even if it is Xu Fu, the number of pills per furnace can only be kept at five or six at a time.

In addition, it is very difficult to find medicinal herbs, so they are very precious and are generally not rewarded.

External cultivators generally just devour the elixir that increases the essence and blood, that is, the so-called great tonic medicine, like what real person pill, Peiyuan Dan, but it is of little use to them.

But Ju Xian Dan is an exception, it can be said that Ju Xian Dan is a necessary pill for those who practice external skills.

When the Qin State had not yet unified the Six Kingdoms, the Armor Gate of the Wei State would spend a huge price every ten years to trade with the Yin and Yang Family, just for a Juxian Elixir, which shows the preciousness of the Juxian Elixir.

And the things that the armor gate used to exchange, in addition to the medicinal materials, are the external cultivation methods of their armor gate.

This is also the reason why Xu Fan also practiced external skills.

But the external strength is not better than the internal strength, and it is more difficult to cultivate, which is why Xu Fan has been outside the door for five years, and there is no teacher to teach it, and there is no auxiliary thing, plus he spends most of his time practicing yin and yang arts, so the search for external skills has not yet been fully introduced.

When the external and internal forces reached their peak, Xu Fan believed that even the scientific and technological power of the twenty-first world would be difficult to hurt him.

The devil knows if the next world will be a world full of technology.

And the appearance of the Juxian Pill also represents that Xu Fan's strength can be greatly improved again.

Of the twenty-five Juxian Pills, Xu Fan took five of them, and the remaining twenty were handed over to Xu Fu for safekeeping.

Two of them were promised to him by the Eastern Emperor Taiyi, and the other three could be regarded as his alchemy reward.

After all, if the person refining the pill this time was Xu Fu, then it was still a question of whether he could get fifteen Cheng Dan.

Xu Fu's internal force could not support such a long period of refining.

In the end, the reason is that Xu Fu's own strength is too low, it can be said that Xu Fan helped refine this time, and he earned it, he took three more, even if Donghuang Taiyi knew, he wouldn't say anything.

After all, the Gathering Immortal Pill is powerful, and it can't compare to the Immortal Pill.

After getting the Juxian Pill, Xu Fan returned to his Xiyue Pavilion, which was also the single attic given to him by the Eastern Emperor Taiyi after he became the protector of the Dharma.

No matter how he said it, he was also the protector of the Yin and Yang family, and he lived in a small courtyard, which was too shabby.

After returning to Xiyue Pavilion, Xu Fan directly began to practice the external skill, the Xuanjia Gong.

This is the top external skill of the armor gate, cultivated to the highest level, the whole body is as hard as dark iron, invulnerable, invulnerable, invulnerable, even if the temperature is as high as 1,000 degrees, it can also be resisted, and it can also be used to strengthen the five internal organs and enhance the resilience with the power of external strength.

Although it can't reach the point where the head is broken and can continue to live, it's not much worse, at least, it's hard to kill.

And it's not just that the body is hard, once you break through to the fifth layer realm, your arms can have the power of ten thousand catties, which is not much worse than those perverts who are born with divine power.

There are a total of nine layers of Xuanjia Gong, Xu Fan has practiced for five years, and now he has just cultivated to the second layer, that is, the skin is slightly harder than ordinary people, but it is not very prominent.

As invulnerable as the peasant family Qingmei Sanniang, Xu Fan must at least cultivate the Xuanjia Gong to the sixth layer.

As for the seventh layer, it's even more terrifying.

And the eighth and ninth layers above, no one has ever reached.

Even the master of the Armor Gate has only cultivated to the seventh layer, and the eighth and ninth layers above, and the cultivation of each layer is extremely harsh.

On this day, Xu Fan had just refined the third layer of Xuanjia Gong, and the door of his attic was directly kicked open.

He didn't have to think about it to know who was coming.

Sure enough, in the next second, a familiar green shadow appeared in Xu Fan's sight, who was Wei Linglong?

"Brother Xu Fan, you guy, don't tell me when you move a place, let people find it easy." As soon as she saw Xu Fan, Wei Linglong immediately complained.

But from her smiling face, you can see that she is not actually angry.

"You can have this place, it's big." Looking around at Xu Fan's Xiyue Pavilion, Wei Linglong's face was full of admiration.

Everything in the room is complete, not to mention, it is very spacious and beautiful, not much better than those small courtyards.

"Of course, this is also the place where the Dharma Protector lives."

After speaking, Xu Fan stretched out his hand and nodded Wei Linglong's head.

"And you girl, it's only been a long time since you know that you're going to confront me, don't you know that you're in retreat? How can I tell you that I moved. ”

"Hmph, you know how to bully me." When Wei Linglong heard this, she suddenly snorted coldly, puffing out a bun face, looking very cute.

Xu Fan couldn't help but sigh, this girl has also grown up.

In just a moment, the unhappiness on this girl's face disappeared, and she began to walk back and forth in Xu Fan's Xiyue Pavilion, looking here and there, it was very novel.

You must know that it was the first time she had come to the place where the Dharma Protector lived, and if it weren't for Xu Fan, she wouldn't have been qualified to enter here at all.

Even if she is a disciple of the Five Spirits Xuantong.

"Brother Xu Fan, you are so big here, do you think I can move to live with you?" Xu Fan knew that this girl definitely didn't come to him for no reason, no, the little fox's tail was exposed.
