With Elder Han's help, after a while, the thirteen materials for refining Bigu Dan were ready.

The dosage of each pill was fixed, and Li Yu only needed to add the spiritual liquid one by one in the order written on the pill, and then slowly refine it with the fire of mana.

It should be noted that these elixirs are mixed together, and the spiritual power contained in them is extremely violent, and when refining, you need to be very careful, and if you are not careful, you will explode the furnace.

Han Tiancheng stayed by Li Yu's side, ready to deal with emergencies at any time.

Of course, he is so good to Li Yu, and he also has his careful thoughts.

As an alchemist, who doesn't want to get a glimpse of the mysteries of the realm of heaven and man, he can watch Li Yu's alchemy with his own eyes, which can be said to be the first to get the moon near the water, and of course he will not waste such an opportunity.

Li Yu added the spiritual liquid in order, and then began to refine the pill.

The biggest difference between refining a first-order pill and a low-level pill that does not enter the flow is that this time the pill liquid contains powerful energy, which is not so easy to control, but fortunately, Li Yu's mana is deep and has exceeded the ninth layer of qi refining, which is not a big difficulty for him.

After a full hour, Li Yu breathed a sigh of relief and withdrew the mana fire.

At this hour, Han Tiancheng looked at Li Yu without blinking, his eyes were sour, but he still didn't get a glimpse of the mystery of the realm of heaven and man.

He rubbed his eyes and asked, "How's it going?" ”

Li Yu opened the Dan furnace, and eight white pills with three Dan patterns appeared at the bottom of the furnace.

He shook his head and said, "It is worthy of being a first-order elixir, there is not even a super grade, and the number is less than ten ......"

This is not a competition, and there is no Tongmai Dan reward, so Li Yu did not open the hanging, I thought that he could bake at least ten of them, of which there were one or two super grades, it seems that he still overestimated his strength.

Han Tiancheng pursed his lips and didn't say anything.

When he first refined a pill, even the Dan furnace exploded, and it took ten times to finally refine one, but there was still only one Dan pattern, an inferior pill that could not be taken, and the comparison between the two was really speechless......

The dominance of the three spirit veins in the Dan Dao was simply terrifying.

A smile appeared on his face, and he said, "Congratulations, Li Yu, it's the first time you've refined a first-order pill, it's already very good to be able to practice like this, some first-grade alchemists, who have been refining a hundred years of pills, are not as good as you......"

After a while, Li Yu returned to his small courtyard with a pile of books.

I have to say that Elder Han is still very good to him, these books are all some advanced books about Dan Dao, and there are also Elder Han's own alchemy notes on them, which can be described as a relief for Li Yu, who is about to take the first-order alchemist exam......

In the world of cultivating immortals, alchemists also need to be examined.

From Dandao apprentices, first-grade alchemists, second-grade alchemists, third-grade alchemists, to fourth-grade alchemists, every time they are promoted, there is a set of standard processes, and the major sects are basically the same.

The alchemist of the Kunlun sect is the most recognized by the immortal cultivation world, if he can't get along in Kunlun, he will basically get a high courtesy if he goes to any sect.

Li Yu is now only a Dan Dao apprentice, and he needs to go through the assessment before he can be promoted to a first-grade alchemist.

The first-grade alchemist assessment requires the alchemist to refine three first-order pills, and the success rate cannot be too low, at least three materials are successful, and through this assessment, you can officially become a first-grade alchemist and enjoy the treatment of the secretary of the sect......

For the sake of his annex and secretary, in the next few days, Li Yu took out the strength of the college entrance examination that year and carefully studied these Dandao books.

There are many first-order pills, the most classic of which are Bigu Dan and Huiqi Dan, these two pills require the least amount of materials and have the mildest medicinal properties, which are suitable for Dan Dao apprentices who want to be promoted.

In addition to these two elixirs, there is also an offensive elixir, such as the Flame Burst Pill, the Frozen Pill, the Wood Binding Pill, etc., this elixir has a similar effect to the talisman, it is a one-time consumable, and after throwing it out, it will take the initiative to release various spells, save your own mana, and release it faster.

However, this kind of attacking pill is much more difficult to refine than the Huiqi Pill Bigu Pill, not only is there a lot of materials, but the steps are also more troublesome, it belongs to the most difficult batch of first-grade pills, and it is infinitely close to the second-grade pills.

After careful consideration, Li Yu selected three first-grade pills as the assessment pills for his promotion to first-grade alchemist.

There are three kinds of pills, namely Huiqi Dan, Bigu Dan and Baoyuan Dan.

Huiqi Pill and Bigu Pill are the most classic first-order pills, after being promoted to a first-grade alchemist, you need to refine a certain amount of money for the sect every month, Baoyuan Dan is an advanced version of Liuwei Dihuang Dan, after taking it, it can warm the kidneys and strengthen the yang, replenish blood and strengthen the body, and can also treat kidney essence deficiency.

Of course, Li Yu didn't need this thing, but at the cost of a bottle of Yangyan Pill, he asked Senior Sister Xu to do an investigation, and the best and most pill sold in Danxin Pavilion was not Huiqi Dan, nor Tongmai Dan, but Baoyuan Dan.

The body of an immortal cultivator will increase with the improvement of cultivation, but this enhancement is strong on the outside, and if it is used too much in some aspects, it should be void or empty.

In addition, some of the foundation building elders of the sect, whose longevity is about to end, look back on their lives and find that they have been practicing hard all their lives, but in the end they still have no chance to marry Dan, and before they die, they want to experience a happiness that they have never had......

But at this time, their bodies have already aged and are in deficit, and they are no longer the majesty of the past, and the demand for Baoyuan Dan is greater.

There are also those male disciples who try to take a shortcut to build the female elders, their cultivation is not high, and their physique is not much better than that of mortals, and they need this elixir even more, and it is a frequent and large need.

After Li Yu became a first-grade alchemist, he had to find a way to earn spirit coins to support himself and his little secretary, of course, he would refine whichever pill sold well.

Li Yu originally wanted to try it now, but he didn't have an alchemy furnace to refine a grade of pills, nor did he have the materials needed to refine those pills, this is the disadvantage of having no background, those genius alchemists in the sect have high-level alchemist masters behind them, and they don't have to worry about these things at all......

He planned to ask Wu Tong to see where he could get these medicinal materials, this kid was well-informed, and Li Yu remembered that not long after he came to the sect, he got a material for the Huiqi Pill.

He had just walked into the courtyard when there was a knock on the door outside.

Li Yu stopped and said, "Please come in." ”

The courtyard door was slowly pushed open, and Li Yu saw a very surprised person.

A few days ago, the Dan Dao apprentice was above Dabi, and the genius girl who was refining the Dan next to him.

One of the two is the top of the big competition, and the other is the third of the big competition, and Li Yu has never had any communication with her except for a brief conversation in the first round.

They are just one side, what is she doing with herself?

The girl smiled at Li Yu and said, "Hello, Senior Brother Li. ”

Although I don't know what her purpose is, she is very polite, and Li Yu also politely replied: "Hello Senior Sister Zheng, is there anything wrong?" ”

The girl smiled slightly and said, "You can't come to Senior Brother Li if you don't have anything, everyone is an alchemist, you can discuss Dan Dao if you have nothing to do, Senior Brother Li's Dan Dao attainments, I also admire ......"

She caught a glimpse of a few books that Li Yu had placed on the stone table in the courtyard and asked, "Senior Brother is preparing to participate in the first-grade alchemist assessment?" ”

Li Yu nodded and said, "Yes." ”

Senior Sister Zheng said, "It just so happens that I have been trying to refine a first-order pill recently, and we can communicate." ”

Li Yu said embarrassedly: "I don't have the spirit herb elixir to refine the first-order elixir, nor do I have a Dan furnace, and I'm still in the stage of reading books." ”

Senior Sister Zheng waved her hand lightly, and on the stone table in front of Li Yu, a Dan furnace appeared, a bunch of elixirs and spiritual herbs, she smiled and said to Li Yu: "I have it, Senior Brother Li can try it, if these materials are not enough, I will go back and get some ......"

At this time, Li Yu had to envy the disciples of these high-level alchemists.

Not only does each person have a storage magic weapon, but the resources he enjoys are not comparable to him.

The growth of an alchemist requires a large number of spiritual herbs and elixirs to practice, and without the support of huge resources behind them, it is difficult to cultivate a high-level alchemist.

There will be no pie in the sky, Senior Sister Zheng must have another reason for being so generous.

She is not Jiang Li, and she will not give Li Yu so many things in vain.

For her generosity, Li Yu shirked a few words, and then accepted it calmly, after all, if he wants to participate in the first-grade alchemist assessment, he also needs a lot of materials to practice, and the alchemy materials sent to the door should not be in vain.

She is the one who has a plan, and I believe that it won't be long before Li Yu will know what kind of medicine she sells in her gourd.
