In Chaoge Xiancheng, small streets and alleys.

A small alchemy workshop located in a remote location.

A elixir furnace in the courtyard is almost idle all day long, with spiritual charcoal added from time to time and burning the raging fire. One furnace is released in an hour, and at least ten low-level elixirs must be refined every day.

In this flash, a year has passed.

Su Chen's alchemy technique also improved rapidly in the ten furnaces of alchemy day after day.

Other monks usually start with an alchemy apprentice. At this time, they just help the master do some miscellaneous work. They don’t operate the master’s alchemy. They have to follow the alchemist for at least five to ten years before they can operate the alchemist.

After a long apprenticeship period, I was allowed to open the furnace to refine alchemy independently. However, the number of times was limited, often ten days, and half a month had the opportunity to refine alchemy. It took another five years before I became an alchemist and tried to refine alchemy by myself.

After you have rich experience, you can become a real alchemist after 10 or 20 years and you can lead an alchemist to take an alchemist.

Su Chen skipped the long and extremely long apprenticeship period of alchemy, bought a jade alchemy slip and a low-level alchemy formula, and then started to refine the alchemy directly.

In just one year, he even made more alchemy times than some alchemists. The failure rate at the beginning was extremely high, but the cost of low-level alchemy was extremely low, so he could also lose money.

During this year, Su Chen's success rate of elixir production also changed from the first ten furnaces to the first one furnace to the second furnace, until the most recent third and fourth furnaces.

He also started to refine some slightly difficult first-level top-level spiritual pills from the lowest level first-level low-level spiritual pills.

If ten furnaces can be successfully refined three furnaces and more than four furnaces, this is already the strength of a high-level alchemist. This still cannot guarantee that the alchemist can earn spirit stones, and it will still lose money.

Over the past year, Su Chen's cultivation level also reached the second level of Qi Refining Stage. Because it was in the early stage of Qi Refining, his cultivation and improvement were still rapid. The Qinglian Yuanshen in Lingshan grew a second lotus leaf.

In order to concentrate on refining alchemy.

In the past six months, Su Chen no longer cares about the business of Linggu, Lingzi and Lingdan.

He just occasionally left Chaoge Lingshan, went to the Linggu Farm at the foot of the mountain for a walk, and then purchased some Linggu back. He also mixed the Linggu he had planted, greatly increasing profits.

Without knowing the gods, no one knows that there are more spiritual valleys out of thin air.

This amount is not much, even Anu cannot detect it, let alone others.

The spiritual valley he planted himself, as well as a small amount of spiritual medicinal materials, and the low-level spiritual pills he refined were all handed over to Annu to go to Chaoge Night Market to sell for spiritual stones.

Anu is still a mortal, so it is not safe to do this business alone.

Brother Zhang often stays idle at home in the evening, so he and Anu go to the night market to help set up stalls to sell some spiritual valleys and elixirs, and can also earn some spiritual stones.

Su Chen spent more than a year and accumulated nearly 10,000 spiritual stones.

If you buy this spiritual stone, you will spend it if you buy ten pieces of spiritual stone and still cannot achieve the goal he wants.

Su Chen didn't plan to buy it, so he decided to practice it himself.

He bought a low-level marrow-cleaning pill formula from the shopkeeper of Zhou's Lingdan Pavilion at a high price.

Then, he used most of the spirit stones he earned this year to plant the thirty first-level spiritual medicines needed for the low-level marrow cleaning pill.

These spiritual herbs are very old, often for decades and over hundreds of years. It took him nearly half a year to plant these spiritual herbs in Lingshan.

The reason why the marrow cleaning pill on the market is so expensive.

A large part of the reason is that the growth period of dozens of spiritual medicinal materials required is dozens of years. Such spiritual medicinal materials are very rare even in the Immortal Cultivation Family Medicine Garden in Chaoge Fairy City.

On the one hand, we need to hire immortal cultivators to cultivate these spiritual medicines, which is a long-term expenditure.

When spiritual medicine is cultivated, a senior alchemist needs to refine these spiritual medicines into spiritual medicines. The alchemist must take at least 30% of the profit.

Then, the marrow-cleaning pill was sold in Lingdan Pavilion, and a small amount of profit was made by the dan Pavilion.

The real medicinal cost of marrow cleaning pill should be about one-fifth, or even lower.

Su Chen used the spirit stones to go to the night market and bought the seeds of the spirit medicine in the spiritual medicine garden, and then used the spirit stones to increase the spiritual energy and planted them in Fangcun Lingshan. The cost was less than one-tenth of the selling price.

Su Chen got a formula for a low-level marrow cleaning pill, and used most of the spirit stones he earned this year to cultivate dozens of spiritual medicines for marrow cleaning pills.

"It's been a year, and I'm finally ready!"

Su Chen breathed a long sigh.

This year, he studied the alchemy technique in the alchemy jade slip alone, and refined more than a thousand furnaces of spiritual elixirs, and suffered all kinds of hardships.

The heat is too fierce, and the furnace is frying and the oven liquid is sprayed out, which happens from time to time.

It is even more common that the elixir in the alchemy furnace is burned or the pill is not condensed.

The mastery of the heat and the timing of producing the elixir are the most difficult thing to control in the alchemy process. This requires a lot of experience in alchemy to make perfect.

Su will place the spiritual medicinal materials that have refined the marrow-cleaning pill.

I spent tens of thousands of spiritual stones and planted a total of 100 pieces of spiritual medicinal materials, which cost only 100 pieces of spiritual elixir. The marrow washing pill that can be used to refine 100 furnaces.

If it succeeds, each furnace can produce a marrow-washing pill. Of course, if it fails, the medicine burns the pill to destroy it.

This is his entire possession.

In fact, spiritual pills can also be refined together with ten spiritual pills and medicine materials, and ten spiritual pills are produced at a time to save time. But this requires very clever alchemy techniques. In order to reduce risks, Su Chen only refines one spiritual pill of spiritual medicinal materials at a time.

"Destroyed!"

"Destroyed again!"

Su Chen buried his head in front of the small alchemy furnace, carefully adding spiritual charcoal, staring at the fire, and controlling the fire. He refined ten furnaces a day, and except for a brief rest for one or two hours, he was infusing the spiritual elixir all over his body.

The ten furnaces that were refined at the beginning were destroyed and none of them were refined, which made Su Chen very painful.

In just one day, a thousand spirit stones were smashed into it, and all of them were wafted. If this were an ordinary alchemist, he would have lost his fortune and had lost his pants and wanted to jump into the river.

However, such a low elixir yield rate is actually a normal phenomenon.

Su Chen has just begun to try to refine the Marrow Cleansing Pill.

Even if an alchemist is just starting to refine a brand new spiritual pill, and is not familiar with the medicinal properties of herbs, the probability of refining is extremely high. Ten furnaces, or even dozens of furnaces, cannot produce spiritual pills.

Su Chen failed to refine this marrow-cleaning pill many times. When he found that something would go wrong, he avoided it and gradually mastered some tricks.

After twenty furnaces, he grasped the heat and finally refined the first marrow-cleaning pill.

Four days later, Su Chen refined forty furnaces in one breath, and finally fully mastered the medicinal properties of the marrow washing pill, which was very easy to refine.

His elixir success rate began to soar, rapidly increasing to about 40%.

Ten days later, all the marrow-cleaning pills were used up, and the fire of the alchemy furnace finally went out.

Su Chen's face was covered in charcoal dust, and his face was a little black, but he could not resist the joy and excitement in his eyes. There were thirty-five marrow-cleaning pills in his spiritual pill bottle, and he couldn't help but be happy.

The golden and crystal clear marrow-cleaning pills emit an extremely attractive fragrance, as if showing off their value as spiritual pill treasures.

"The marrow-cleaning pill is made!"

Su Chen was extremely excited. After working hard for a whole year, he finally achieved this huge achievement by planting medicines and practicing alchemy day and night.

He could not wait to cleanse his marrow again and break the bottleneck of his spiritual marrow.

Su Chen directly sat cross-legged in the small alchemy workshop, and adjusted his breathing for an hour.

Then, a marrow-cleaning pill was thrown into his mouth.

It slid into the abdomen and melted into golden medicinal liquid, which penetrated into his body and absorbed on his spiritual marrow. The medicinal power of these marrow-cleaning pills penetrated into the depths of the spiritual marrow, constantly cleaning the spiritual marrow.

The process of washing the spirit marrow is like ten thousand ants eating bones, which is quite uncomfortable.

Half an hour later, a little impurities and dirt in the spiritual marrow were washed out, and the effect was still very obvious.

OK, the marrow cleaning effect is good.

continue!

Another one!

Su Chen took a break and stuffed another one into his mouth and continued to wash the marrow.

After one hour.

Come again!

Su Chen kept on one after another.

Before I knew it, two days passed by in a flash.

The marrow cleaning pill in this marrow cleaning pill bottle is decreasing at a speed that is visible.

Su Chen had taken fifteen marrow-cleaning pills in a row, washing away a large part of the impurities in the spiritual marrow and became much purer.

at this time.

Su Chen was surprised to find that although the same marrow cleaning pill, the effect of marrow cleaning began to slowly weaken. When he took sixteen pills, he had no effect of marrow cleaning at all.

"What's going on? Can't continue to cleanse the marrow?"

"If I wash two points of one marrow washing pill, my spiritual marrow must have just reached sixty o'clock. I just reached the edge of the top-grade spiritual marrow, and it's still early from seventy or eighty o'clock."

Su Chen was puzzled and suddenly thought of a question.

Drug resistance!

Could it be this reason?

This issue has also been mentioned in alchemy. This resistance usually occurs in spiritual elixirs. Their medicinal properties are very strong, and monks can easily develop drug resistance after taking it for a long time.
