Xu Yi stayed in the alchemy room for an hour and a half before returning to his yard.

During this one and a half hours, Lu Fang taught him all his heart. Of course, all his knowledge was limited to the elixir of Zhuangqi Wan.

Before a normal alchemist comes into contact with the alchemy furnace, the first thing he needs to do is to go to the medicine garden to study. They need to master a lot of knowledge, including how to identify herbs, distinguish the efficacy and quality of herbs, and know the problem of mutual generation and restraint between drugs.

All these require a lot of time to complete, and may even accumulate normal people's practice time.

However, Lu Fang and Xu Yi ignored it. They taught and learned one by one, limiting all the knowledge scope to seven drugs.

According to Lu Fang, Zhuangqi Pill, the simplest elixir, actually has three different methods of refining medicines. It corresponds to seven drugs, ten drugs and twelve drugs respectively.

Different drugs have different proportions, and the biggest gap is the price and refining difficulty.

Using seven drugs to refine Zhuangqi Pills is undoubtedly the easiest, but its cost is the most expensive. The cost of medicinal materials alone costs 80 taels of silver. Although the number of ten drugs is three more, the cost is 30 taels cheaper. As for Zhuangqi Pills of twelve drugs, the cost has dropped to just 30 taels.

Most of the real alchemists will choose Zhuangqi Pills, the most basic elixir. Their refining methods are from less to more, from easy to difficult. However, once they are thoroughly mastered, most of them will choose twelve drugs during daily refining.

All of this is due to the cost and selling price.

The finished elixirs in the Artifact Pavilion are extremely expensive. There are ten bottles of low-quality Zhuangqi pills, worth thirty taels of silver, ten bottles of medium-quality Zhuangqi pills, worth one gold, and ten bottles of high-quality Zhuangqi pills, worth three gold, and the best Zhuangqi pills have reached a terrifying level of value of three gold.

Moreover, the best medicines are hard to come by, and generally there is no need to rely on. On the contrary, although the top-grade elixirs are scarce, as long as they can pay a sufficient price, they can still maintain the supply.

As long as an alchemist achieves something, he can make money very quickly. Even at the cost of eighty taels of silver for seven drugs, as long as he is successfully refined and his grade reaches a medium-grade level, a furnace of elixirs will make a profit. If he gets the best or best, he will make a lot of money.

However, since Zhuangqi Pills are the most basic elixirs, the supply is huge, due to cost considerations, most primary alchemists will still choose twelve medicines to refine.

But at this moment, Xu Yi only learned the seven simplest and most expensive ways to refine medicinal materials, and he only learned the steps and various precautions for exercise. As for how to pick and preserve medicinal materials, it was completely ignored.

But even so, when Xu Yi left the Dan Room, he felt dizzy.

He received a lot of new knowledge in a short period of time and witnessed Lu Fang refining three furnaces of elixirs one after another. Anyone would feel that he could not bear it.

Only when you return to the yard can you see the benefits of Xu Yi's intentional choice of the most remote place. There is no one around the yard. Xu Yi will not neglect it, take out the notes and continue, and add a few words from time to time to make his impression more profound.

Not long after, someone brought the alchemy furnace and medicinal materials. The person who sent it was a manager in the warehouse. The alchemy furnace was borrowed by the sect, but the three portions of the medicinal materials charged Xu Yi two gold coins.

That's right, the market price is two gold and forty silver, but the price given to the alchemist by the sect is two gold, which is a small surprise.

With the elixir furnace, there is also a large amount of elixir coal, which is a special fuel, which is different from the coal balls Xu Yi has seen on Blue Star. This fuel is specially used to refine elixirs or forge weapons, and is expensive to the outside world. However, as long as you have the identity of a disciple of the Artifact Sect, the sect will provide it for free.

The depth of the sect for thousands of years shocked Xu Yi again, but it made him extremely happy.

After closing the book, Xu Yi did not directly refine the alchemy, but took a top-quality qi pill, then used the true qi to complete the transportation of a large circle. When the true qi was completed this time, his energy and spirit immediately returned to his peak state.

Although practicing is extremely boring, it is also very enjoyable when circulating true qi. Especially when taking the best elixir, it becomes more and more obsessed.

After one big Zhoutian, Xu Yi's head was no longer dizzy and his body was also no longer tired. He felt refreshed as if he had been sleeping for three days and three nights.

He placed the elixir furnace in the back room and estimated that he would send the elixir coal into the iron frame at the bottom of the furnace. There was an air outlet here to adjust the firepower, but it generally does not require much adjustment to make the basic elixir. It is enough to maintain a certain temperature from beginning to end.

After taking out the seven kinds of elixirs and putting them in, reviewing the notes again, Xu Yi officially began his first alchemy.

These medicinal materials have been processed, but before formal alchemy, the last processing is still required. It is either soaked in water, cut into pieces, or mixed. This preparation alone will take half an hour.

To refine alchemy, it is really necessary to invest medicinal materials into the alchemy furnace until the finished product does not take too long, but instead, the time taken up by the advance preparations is more.

This is equivalent to an exam. One hour of answering questions takes several years or more than ten years of study. It is like cooking. It is not long to really put into seasoning in the pot, but the time to prepare ingredients in advance is the real big deal.

Lu Fang started from the hot furnace and put the first elixir, and to the finished elixir, it took less than a quarter of an hour.

During that hour, he spent most of his time preparing the herbs of three furnaces of elixirs and explaining the key points to Xu Yi. However, the time he actually refined the three furnaces of elixirs was only about two quarters of an hour.

Now, it took Xu Yi a whole hour to complete the preface of a medicinal material.

He looked at the ground, confirmed that he had no mistakes, and then directly activated his magical powers to expand the seven treated herbs three times.

After doing all this, he actually felt breathless. But it was worth it because it saved him a lot of time.

To calm down, Xu Yi took a top-quality qi pill. After a quarter of an hour of practice, his energy and spirit were filled again.

Opening his eyes, Xu Yi lit the elixir coal and began to put herbs into the elixir furnace according to the steps.
