After Xiao Fan returned to the Hollow Academy, he was called to the Dan House by Dan Lao.

"Old man Dan, what are you looking for me? If you ask me to cook for you, you won't be exempted, I won't cook for an old man like you who doesn't speak of trust!" Xiao Fan didn't even look at Old Dan.

Dan Lao smiled, "You look carefully. After Dan Lao finished speaking, he turned around and took out a medicine tripod, as well as more than a hundred kinds of medicinal materials.

Xiao Fan frowned, is Old Man Dan going to alchemy?

Dan Lao's hand was raised slightly, and nearly a hundred auxiliary herbs flew into the medicine tripod......

Dan Lao made a move, and a gray-white fire spirit appeared in his hand, "This is the Heavenly Fire Ash Devouring Fire!"

After Dan Lao finished speaking, he continued to refine the pill, only to see that he put the fire spirit into the medicine tripod and began to refine the essence of the herb.

"The first step in alchemy, extract liquid!" Dan Lao explained while refining the pill.

The meaning of extract is to extract the essence of the herb.

Soon, hundreds of herb essences were refined, and Xiao Fan secretly exclaimed, Old Man Dan was really not simple, he was able to refine hundreds of herbs at the same time.

Dan Lao took out another herb at this time, "This is a rare herb Hui Tian Cao, the main herb for refining Hui Tian Dan, since it is a rare herb, it is best to refine it alone." ”

Similarly, with Danlao's skill, the medicinal essence of Hui Tiancao was quickly refined.

"The second step of alchemy, melting qi, melting qi consists of two parts, melting the demon core and melting the zun crystal! ”

Dan Lao took out a magic core and a diamond-shaped crystal at this time, "This is the spirit beast demon core and the Venerable Crystal!"

Xiao Fan fixed his eyes on the diamond-shaped crystal, didn't there be a lot of this kind of thing in the ring he got from the "Water Curtain Cave" last time?

Xiao Fan was overjoyed, he didn't expect that he already had so many Zunjing.

Dan Lao quickly melted the Demon Core and Zun Crystal, and the Qi of Heaven and Earth transformed by the Demon Core and Zun Crystal wrapped the essence of the herb that had been refined first.

"The third step of alchemy, Ning Dan!" After Dan Lao finished speaking, he used the ash devouring fire to wrap the essence of the herb and the qi of heaven and earth for warmth.

Soon, "Condensation!" I saw that the qi of heaven and earth and the liquid medicine suddenly shrank, forming a white pill and flying into Dan Lao's hand.

Dan Lao smiled, "This is a pinched pill to return to the heavens!"

Xiao Fan opened his mouth, at the beginning, they fought for the life-and-death Huitian Pill in the competition of the four major families of the Xiaoyao Empire...... It's so easy to refine!

Xiao Fan scratched his head, "Eh, teacher, can you tell me how many pills there are?"

"How many grades? Most people say there are nine grades, but some people say that there are ten grades. ”

"Oh, that means that the higher the number of products, the better the elixir!"

Dan Lao shook his head, "No, the first to third grades are the Zun Dan, the fourth to the sixth grade are the Holy Pill, and the seventh to ninth grade is the Emperor Dan, as for the different names, in fact, different heaven and earth qi are added during the alchemy." ”

Xiao Fan was still puzzled, "What do you mean?"

"That is to say, there are only three grades of the pill, and the fourth to ninth grades are just upgraded versions of the pill, such as the Huitian Dan, if the Holy Qi is added when refining the Huitian Pill, then the Huitian Pill will be upgraded to the fourth grade of the Huitian Pill, if the Emperor Qi is added, then the Huitian Pill is the seventh-grade Huitian Pill, but the Imperial Qi is very riotous, and it is impossible to control the Imperial Qi without a certain strength, and the Holy Qi is the same, and it is difficult to refine the Holy Pill without strength. ”

"Oh......" Xiao Fan suddenly realized.

Dan Lao continued, "However, it is not that the higher the number of grades, the better the pill, let's just say that the four-grade Saint Pill is often not as effective as the three-grade Zun Dan. ”

Xiao Fan thought for a moment, "Teacher, what if you add divine energy to alchemy?"

Dan Lao paused, as if he didn't know how to answer Xiao Fan, "...... If you join the gods...... That's the legendary ten-grade elixir, the Divine Pill!, however, it's just a legend after all, because even a god can't quote the divine qi 100%......"

Xiao Fan thought about it, this question was too profound, Xiao Fan simply didn't want to, "Teacher, can I do alchemy?"

Dan Lao didn't speak, and threw Xiao Fan a Dan Fang.

Xiao Fan looked at the Dan Fang, he knew all the herbs, a total of one hundred and twenty-six kinds of medicinal herbs, including three layers of leaves, the Dan is called the Barrier Breaking Pill!

Xiao Fan turned around and asked Dan Lao, "Teacher, how many pills are this?"

Dan Lao smiled mysteriously, "Yipin." ”

Xiao Fan's confidence was full at this time, and he must refine the barrier-breaking pill at one time.

"Teacher, borrow your medicine for a while. ”

Dan Lao nodded, "Yes, you can also use the remaining auxiliary herbs on the ground." ”

Xiao Fan was very excited, he had wanted to refine the pill for a long time, and suddenly, Xiao Fan thought of something, "Teacher, I don't have a ...... for Zunjing"

"I forgot about that...... Here you go!" Dan Lao gave Xiao Fan a Zun Crystal and a Spirit Beast Demon Core.

Xiao Fan took the Zun Crystal and the Demon Core, and recalled the alchemy steps of Dan Lao just now, "Extraction!"

Xiao Fan also made a move, learned from Dan Lao to put all the auxiliary herbs into the medicine tripod, and then began to refine it with Zizai Yan.

The corners of Dan Lao's mouth twitched, this kid actually wanted to refine the herbal essence of the auxiliary herbs at one time! He was able to do it because he had been refining the Dan for decades.

However, Xiao Fan actually did it, and it took half an hour to refine all the auxiliary herbs.

Dan Lao had to marvel at Xiao Fan's talent in his heart.

Xiao Fan took out a three-layer leaf at this time, which he got in the Beast God Forest.

Since it was very smooth before, Xiao Fan was full of confidence, but when extracting the three-layer leaf herb essence, Xiao Fan felt that it was much more difficult than before.

Xiao Fan had already begun to sweat at this time. A quarter of an hour passed, and Xiao Fan finally completed the first step.

"Step 2, melt the air!"

Xiao Fan took out the magic core, put the magic core into the medicine pod, and began to melt the magic core.

Xiao Fan was sweating even more at this time, and it was really a bit difficult for him to keep the essence of the herb and melt the demon core now.

Xiao Fan had already scolded secretly in his heart, damn, how could Old Man Dan be so relaxed when he was refining just now!

It took another half an hour for Xiao Fan to melt the demon core.

Xiao Fan began to melt Zun Jing at this time, Zun Jing was as difficult to melt as the demon core, Xiao Fan felt that he was about to collapse, but he still gritted his teeth and insisted.

"The third step, Ning Dan!" Finally, Xiao Fan melted the Zun Jing, and now the last step of alchemy begins, Ning Dan! But Xiao Fan's whole body is now soaked in sweat.

Xiao Fan used the Freedom Flame to wrap the Qi of Heaven and Earth and the essence of medicinal herbs.

At this time, Xu Yan and Qian Yingying appeared, and they found that Xiao Fan was alchemizing, and Dan Lao was watching from the side.

Xu Yan and Qian Yingying walked over, and Qian Yingying looked surprised, "Wow, Senior Brother Xiao can actually refine the pill!"

Dan Lao hurriedly put his finger to his lips, "Shhh ”

At this time, Xu Yan asked Dan Lao in a low voice, "Teacher, what kind of Dan is Senior Brother Xiao refining?"

Dan Lao's face was indifferent, "Barrier Breaking Dan!"

Xu Yan looked surprised, "Can ...... But hasn't Senior Brother Xiao ever refined the pill yet? The Barrier Breaking Pill is a second-grade pill! Can he succeed?"

Dan Lao smiled, "It's his talent!"

Xu Yan was even more surprised, thinking to himself what kind of person Xiao Fan was, he could actually let Dan Lao say this, even if it was himself, he could only refine a grade of pills.

"Condensation!" Xiao Fan shouted at this time, but the mass of herb essence did not move at all.

Dan Lao slowly spoke, "Ning Dan is the most difficult step in alchemy, you must not be in a hurry, you must use fire to slowly warm up, so that the qi of heaven and earth and the essence of medicinal herbs can naturally merge!"

Only then did Xiao Fan calm down and slowly warm up the essence of the herbs and the qi of heaven and earth.

After almost an hour, "Condensation!" Xiao Fan shouted, at this time, the essence of the herb and the qi of heaven and earth finally began to merge, Xiao Fan was already gritting his teeth, if he didn't succeed this time, he would fall.

Finally, the qi of heaven and earth suddenly shrank, and the pill was completed!

A cyan pill flew in front of Xiao Fan, but Xiao Fan slowly closed his eyes at this moment and fell!

Dan Lao hurriedly helped Xiao Fan, picked up Xiao Fan's pill, and looked at it, "Well, that's good! Xu Yan, you help him go back to rest!"

"Yes, teacher!" Xu Yan was already completely shocked, Xiao Fan was the first time to refine the pill, and it was also a second-grade pill, and it was actually successful at one time.

Then Xu Yan and Qian Yingying helped Xiao Fan go back to rest.
