Immortal Space

He had already started cultivating Yangyuan grass and other elixir for refining Yangyuan pill a few years ago.

However, due to the limited space and its long growth period, he has only accumulated more than 500 materials so far.

Each Yangyuan Dan material is worth about 500 spirit stones, and these more than 500 materials are worth nearly 300,000.

An alchemist who can refine first-order alchemy in the world of cultivating immortals is called a first-order alchemist.

Since the supply of first-order elixir is relatively sufficient, and most of them are not expensive, as long as you are willing to spend about 50,000 spirit stones, you can train a first-order alchemist.

Therefore, although there are not many first-level alchemists, basically every decent family or faction will have one or two.

Although the investment is relatively large at the beginning, as long as it is successfully cultivated, it is equivalent to an old hen that can lay golden eggs, and there will be a steady stream of income in the later stage. As long as the financial resources are sufficient, it is still very cost-effective.

And the number of second-tier alchemists is extremely scarce. First of all, the resources needed to train second-tier alchemists are a huge amount. Even if you sell all the small families, you can't gather so many resources.

Even if some middle-level forces can barely gather these resources, it will not take a day or two, and it will often take decades.

In the end, after working hard to cultivate a second-level alchemist, he will face a serious problem, that is, there is no elixir to refine.

The second-order elixir grows slowly, ranging from one to two hundred years to as many as six to seven hundred years. During this long period of time, sometimes several batches of people died, and the elixir may not be able to be cultivated.

It is also very difficult to buy elixir, which leads to the fact that second-tier alchemists often have no alchemy to make. If they are unlucky, they will not even be able to earn back the cost of training alchemists.

Refining the second-order elixir requires the use of the second-order spiritual charcoal. The firepower of the first-tier spiritual charcoal is already insufficient to effectively melt the elixir, refine impurities, and extract the essence.

Second-order spirit carbon needs to be refined with second-order spirit wood, and the price is not cheap. One piece of spirit carbon needs thirty spirit stones.

There was no spiritual wood planted in the space for refining spiritual charcoal, and he cut down densely grown branches from those second-order spiritual fruit trees.

Cut these branches into two or three feet long, put them into the alchemy furnace, cover it, and then calcinate it with first-order spiritual carbon.

In some workshops for refining spiritual carbon, there are specially built carbon kilns.

Anyway, Wang Hong didn't use much by himself, and his alchemy furnace was so huge that it could just be used to temporarily refine some spiritual charcoal.

The spirit charcoal refined from spirit fruit branches is of better quality than the spirit charcoal sold in the market.

It's just that the shape I made by myself is not so regular, and the charcoal that is fired still looks like a branch.

Anyway, I'm using it myself, and I don't plan to sell it, so what the heck.

Wang Hong took out a piece of Yangyuan Pill material and placed it beside the pill furnace.

He made a cup of spiritual tea first, using the spiritual spring water and spiritual tea in the space. The spiritual tea in the space has the effect of eliminating fatigue, clearing the mind and sharpening the mind.

Drinking a cup of spiritual tea beforehand should increase the success rate.

After everything was ready, he started alchemy.

He took a few spirit charcoal like branches and put them under the alchemy furnace to ignite them, and then played a few fire control formulas towards the flames to adjust the size of the flames to a suitable position.

Wang Hong sensed the temperature in the furnace, and threw a stalk of Nourishing Grass into the alchemy furnace, but the firepower seemed to be insufficient, and the Nourishing Grass showed no signs of melting.

He once again shot two spiritual formulas at the flame, the flame rose rapidly, and then a burning smell came out.

The fire was too big, the nourishing grass was scorched, and it was destroyed at the first step.

However, Wang Hong wasn't annoyed at all. He was not familiar with the temperature of the flame and the characteristics of these types of elixir when refining a second-order elixir for the first time.

Readjust the flame and put in the elixir again. With the experience from last time, the elixir melted into a green liquid medicine smoothly this time.

Then gradually put other kinds of elixir into it, and it turned into a large mass of liquid in the alchemy furnace.

The next step is to refine the impurities. If the impurities are not refined in this step, all the pills will be refined in the end. On the contrary, it is also possible to refine the essence in the elixir, and there will be nothing in the end. It is a failure, so the heat must be mastered.

Wang Hong carefully tried to increase the firepower, and slowly, a faint mist evaporated from the liquid medicine, which was the refined impurities.

After a stick of incense, use the fire control formula again to slowly lower the firepower. Now it is necessary to fuse various ingredients in the medicinal liquid to make the various medicinal properties reach a balance and coordination.

His hands changed like phantoms, and he played hundreds of formulas. These formulas are only used in refining second-level pills. He practiced for a long time in advance, and only dared to start alchemy when he was completely proficient.

However, at this moment, the spiritual power in the pill furnace suddenly became extremely violent, and all kinds of spiritual power collided with each other, and finally there was a loud noise, a puff of black smoke came out, and the furnace exploded.

Wang Hong cleaned up the pill furnace, thought for a while quietly, and started refining the next batch of pills again.

The third furnace, still a failure.

Fourth furnace, failed.

...

Finally, the tenth furnace was successful, and I got a second-order Yangyuan Pill.

Then the eleventh furnace failed again, and after the fiftieth furnace, it finally stabilized, with an average of one or two grains of three or four furnaces for every ten furnaces.

The comprehensive alchemy rate is less than 10%, and the Yangyuan Dan must reach at least 20% of the alchemy rate to save money. His current level is equal to how much he loses.

This is also due to his solid foundation in alchemy, and his refining of first-order elixirs has now reached the point of proficiency.

Moreover, he has studied the basic knowledge of various medicinal properties and pharmacology for a long time, making it much easier for him to make alchemy than others.

If it were someone else, even if he refined a hundred furnaces, he might not be able to reach his current level. It must be known that the refining of second-level pills is more than ten times more complicated than that of first-level medicine.

Wang Hong rested for a day after finishing one hundred furnaces, cooked himself a table of delicious food, drank some wine, and relaxed.

A day later, he started alchemy again. This time he refined another hundred furnaces in a row, and made some progress. Now almost eight out of every ten furnaces can see the pills, and the comprehensive alchemy rate has finally reached 10%.

He rested for another day. This time when he was refining alchemy, he added some spirit bee royal jelly to it, which could increase the rate of alchemy.

He hadn't used it when refining the first-order elixir before, because when he got the spirit bee, his alchemy rate was already very high.

Moreover, most of the first-order elixirs are not as expensive as the royal jelly of the spirit bee, and they will lose money if they are added. Now when refining the second-order elixirs, one more pill per furnace can be worth the price of the royal jelly of the spirit bee.

As for the previous hundreds of furnaces, most of them didn't even have a single elixir, so it would be useless to add the royal jelly of the spirit bee.
