Longevity: Never leave the mountain until you are invincible

"Being a master of alchemy requires a lot of time of practice and the support of a large amount of elixirs. It is not an easy task."

Chu Chen briefly read through the Five Qi Alchemy Sutra and understood how difficult it was to make elixirs.

Compared with drawing talismans, refining alchemy requires more energy and is more difficult.

And the cost of refining alchemy is even greater.

The biggest cost of drawing talisman is the talisman paper. As long as there is enough talisman paper, you can practice drawing talisman.

But alchemy is different.

Just the various elixirs needed to make alchemy are enough to make the alchemist overwhelmed.

Usually, elixirs that are one or two years old are worth a lot of money, let alone elixirs that are more than ten years old, which can easily cost thousands of low-grade spiritual stones, and they are expensive but have no market.

Furthermore, refining alchemy is the same as drawing talismans, and there is also a problem of success rate.

Once the alchemy fails, all the elixirs used will be scrapped. There is no such thing as recycling.

One can imagine how costly the failure of alchemy would be.

"As for me, I don't need to worry about this problem for the time being. After all, elixirs are hard to find in the world. There is no elixir for me to refine high-level elixirs."

Chu Chen smiled.

Due to the shortage of materials, at this stage he can at most refine some low-level elixirs.

These elixirs can be refined using common traditional Chinese medicinal materials that are one or two hundred years old.

certainly.

The elixir refined from common medicinal materials would not have much effect on Chu Chen's cultivation.

"However, these elixirs are very useful for warriors who practice martial arts and can be used to cultivate chess pieces."

After a second thought, Chu Chen thought of the role of these elixirs.

At the same time, refining these elixirs can help him gain experience in refining higher-level elixirs.

Just like drawing talismans, alchemy also requires starting from low-level elixirs and accumulating experience step by step. When you have enough experience, you can then refine high-level elixirs.

"After refining the Five Qi Pill Furnace, you can try to refine the pill."

Chu Chen's heart condensed.

The Five Qi Alchemy Furnace is an alchemy weapon. In the process of alchemy, it helps the alchemist far more than imagined.

Not only can it improve the success rate of alchemy, but it can also improve the quality of the elixir.

He planned to wait until the Five Qi Pill Furnace was refined before trying to refine the pill.

Besides, we can't let the Five Qi Dan Furnace occupy the secret room all the time.

Chu Chen sat cross-legged, poured his own magic power into the Five-Qi Pill Furnace, and began to refine the Five-Qi Pill Furnace.

Refining the Five Qi Alchemy Furnace is much more difficult than refining the Blue Sky Mirror and the Soul Sensing Mirror. Although they have all fallen into embryonic magical weapons, the essence of the Five Qi Dan Furnace is stronger than the original Blue Sky Mirror and the Soul Sensing Mirror.

However, Chu Chen has broken through the fifth level of Qi training and has strong magical power. The speed of refining magic weapons is naturally much faster. Over and over again, his speed of refining the Five Qi Pill Furnace is no slower than refining the Blue Sky Mirror and the Inspired Mirror.

Three years ago, shortly after returning to the imperial capital from Xizen Temple, he successfully broke through to the fifth level of Qi training.

To be honest, this speed is a bit slow.

This is related to the fact that Chu Chen was distracted by other things, such as drawing talismans, practicing spells, practicing God Refining Techniques, etc., which took away a large part of his energy, so that it was only now that he had broken through the fifth level of Qi training.

Six days later.

Chu Chen completely refined the Five Qi Pill Furnace.

"Small!"

With a thought in Chu Chen's mind, the originally huge Five Qi Dan Furnace quickly shrank, became the size of a palm again, and fell into the cuff of his sleeve.

The Five Qi Dan Furnace has the ability to change its size. When not in use, it can be reduced in size for easy portability and storage.

When you need to use it, you only need to input mana and it can be changed to a size suitable for alchemy.

"It's a pity that the Five Qi Pill Furnace is only used for elixir refining and cannot be used as an offensive weapon."

Chu Chen felt a little sorry.

Whether it is the Qingtian Spiritual Mirror or the Five Qi Pill Furnace, they are all auxiliary magic weapons and have no power against the enemy.

If the enlarged Five Qi Dan Furnace could be used as a weapon to throw out, the destructive power would probably be quite good.

Chu Chen once experimented and found that the enlarged Five-Qi Dan Furnace weighed more than a thousand pounds. Once it was dropped, it would be very lethal.

Of course, the premise is that the Five Qi Dan Furnace is not afraid of being damaged.

"Forget it, it's better not to do this."

Chu Chen shook his head to clear this dangerous thought from his mind.

After all, the Five-Qi Alchemy Furnace is an alchemy weapon. Once it is damaged, it will cost a lot to repair it.

The gain outweighs the loss.

Damage to a magic weapon is not like that after the magic weapon falls, it can be restored as long as it is warmed for enough time. You also need to prepare valuable spiritual materials to repair the magic weapon.

After refining the Five Qi Pill Furnace, Chu Chen did not rush to try to refine the pill, but took out various medical books and read them.

As the saying goes, sharpening your knife will never make you chopping firewood.

Refining elixirs is not something that can be achieved by just talking. It also requires a solid medical foundation and an understanding of the pharmacology and medicinal properties of various medicinal materials.

In this way, we can deal with various emergencies when refining alchemy.

Speaking of which, Chu Chen had a good foundation in medical knowledge. In order to prepare various poisons, he had read many medical books before and had some research on medical knowledge.

Nowadays, picking up medical books can play a role in reviewing the past and learning the new.

Chu Chen later put on the concealment charm and went to the Taiyuan Hospital to borrow the medical books.

Taiyuan Hospital is the holy place of medicine in Dayan, and there are so many medical books in it, which benefited him a lot.

When he has accumulated enough, he will study the Five Qi Alchemy Sutra and learn the method of alchemy.

half year later.

"The medical book and the Five Qi Alchemy Sutra are almost finished, and the medicinal materials are ready. It's time to try to make the elixir."

Chu Chen went to the Yunwu Mountains and entered the cave.

He was going to make elixirs in this cave.

Alchemy requires not only the utensils and medicinal materials for alchemy, but also a flame with a high enough temperature.

The flame produced by burning firewood is not hot enough and not stable enough to be used for alchemy.

If you want to make an elixir, you must use some special flames.

For example, the various spiritual fires condensed by cultivators.

Chu Chen does not have the method to practice this kind of magic, so he can only make the best use of the strange fire nurtured by heaven and earth, such as the lava fire.

In order to solve the problem of his second personality, Pei Zhixuan once imitated the storybooks to cast an alchemy furnace in order to make an elixir.

This cave in the Yunwu Mountains was essentially built by Pei Zhixuan for alchemy.

Under the cave, there is a lava vein that can draw out the lava fire for alchemy.

Boom!

Chu Chen raised his hand, and the Five Qi Alchemy Furnace flew out, quickly grew larger, and fell into the center of the cave.

The alchemy furnace left by Pei Zhixuan had long been thrown away by him.

"Calm down."

Chu Chen sat cross-legged in front of the Five Qi Alchemy Furnace, practicing the Soul Refining Technique to calm his heart.

Alchemy is as delicate as drawing talismans, and one needs to keep calm.

Chu Chen, who tried alchemy for the first time, was a little more nervous than drawing talismans for the first time. He practiced the soul-refining technique three times in a row before clearing all the distracting thoughts in his mind.

"Now!"

Chu Chen raised his hand and sent out a magical power, which aroused the lava fire underground and burned the five-qi pill furnace.

The pill he wanted to refine was called Jingqi Pill, a low-level pill that can enhance qi and blood.

The steps of alchemy can be simply summarized into two steps: throw the prepared medicinal materials into the alchemy furnace one by one, extract the medicinal power, and then melt it into pills.

It sounds simple, but it is extremely troublesome to do.

Each step is tedious and complicated, and requires a lot of effort.

The temperature and heat of the flame are different when extracting the medicinal power of different medicinal materials.

A slight mistake may lead to failure.
