"The most important thing for an alchemist is memory. Although cultivators cultivate spiritual consciousness, their memory has increased greatly, even dozens of times higher than ordinary people! However, the matter of alchemy is extremely complicated, including the regulation of fire, the grasp of time, the application of mantra seals, etc., and even some difficult elixirs, they must be well grasped to add auxiliary spiritual roots. Aside from the slightest bit of a problem, the elixir is likely to be completely scrapped!"

Master Fu Zong said, but his eyelids couldn't help but jump.

The Li Xiao in front of him was the most fierce guy he had ever seen. His memory was like a divine helper. It took only one hour to record all the obscure and difficult curse seals. You know, even if he had to spend ten days to recite it!

"Ahem, this is your first time to refine the elixir. Let's refine the simplest marrow cleaning pill."

The marrow-cleaning pill was a reward given by the National Academy to students who picked spiritual roots. The premise was that students who had to pick a storage bracelet had to receive the reward of the marrow-cleaning pill. It is extremely precious among students of the National Academy, but it belongs to the simplest category of elixirs.

Fu Zong taught Li Xiao the method of refining marrow washing pill bit by bit. The magic of the technique even Li Xiao was a little dazzled.

However, Li Xiao knew that this was just the beginning, so he forced the steps of alchemy to be recorded and imprinted in his mind with his extraordinary memory.

"Okay, that's all, you can try to refine a furnace first."

Master Fu Zong waved his hand and suddenly made a loud noise like a big bell. A red cauldron rose from the ground, which was as high as one person. I am afraid that six or seven people could not hold it together. The flames below the cauldron were burning, and the whole room was burning with heat!

With a great grasp of Master Fu Zong, several kinds of spiritual roots flew into the air. Under the control of Master Fu Zong, they all threw them into the cauldron.

"Quick, make the melting seal!"

With the shout of old man Fu Zong, Li Xiao quickly recited the spell seal, and at the same time used the power of true energy to form a rune, and threw it into the cauldron!

The entire red cauldron began to vibrate, and strands of spiritual energy condensed around the cauldron at a speed that could be distinguished by the naked eye, and were firmly locked in the cauldron.

After about a few breaths, Old Man Fu Zong frowned:

"The temperature is a bit high, apply the temperature control printing..."

"Put the real seal..."

"Put the warming mark..."

About every few breaths, Li Xiao would print a spell seal under the opening of Old Man Fu Zong. With such tedious consumption, Li Xiao was also a little panting. Until three hours later, a furnace of marrow washing pill had been refined.

Li Xiao was as tired as a dead dog, but when he heard that he had successfully refined the first elixir, he couldn't help but feel a little excited. Old Man Fu Zong grabbed the whole cauldron with his hands, and the entire cauldron cover flew up, and a stream of spiritual energy rushed over, and a pile of medicine residue was piled up in it.

"Hunge it into a pill, it is the marrow-cleaning pill. It seems that your first pill is pretty good, and you actually refined a furnace of medium-grade pills. In fact, if you don't make any mistakes, you can refine a top-grade pill that is better than the top-grade pills. After all, I am instructed. If you don't seize the opportunity, it's good to be able to produce medium-grade pills."

Old Man Fu Zong’s meaning is very simple. It is indeed difficult to make mistakes with him. However, whether it is a timing or an emergency, there will be a slight time difference. After all, Old Man Fu Zong said it, entered Li Xiao’s ears, and then thought of the curse seal and then slapped it out. A lot of time has been wasted in this. Only by learning to look at the temperature and seize the opportunity can you refine the top-grade elixir.

As for the best, it depends on luck. You must not make any mistakes or gaps, and you must print the curse seal as soon as possible. You must reach a very skillful level. When you think of the curse seal, you can make it out in your hands instantly without any delay. Moreover, the seal techniques and heat cannot make any mistakes. It is extremely strict, otherwise it is impossible to make the best elixir.

"A medium-grade elixir like this is enough for ordinary elixirs to train muscles and bones. Those elixirs that can enhance their cultivation, as well as the Great Return Pills that can recover from injuries, etc., must reach the top-grade elixirs. As for the more precious sacred medicines for healing, longevity prolonging pills, etc., they need top-grade elixirs. Of course, there is also the supreme elixir in the elixir - Tiandan, which is a holy medicine that crosses the natural barrier. No one has refined it so far, so you have to work hard."

"Yes, younger generations remember."

Li Xiao responded seriously and then followed Master Fu Zong to learn the quality of the time.

According to the characteristics of the elixir, choose the appropriate heat. The lowest-level elixir like the marrow-washing pill requires the lowest temperature among the elixirs, because the medicinal materials used to refine the elixirs are ordinary spiritual roots, which cannot withstand the burning of too high temperatures. The temperature is too low, but it cannot refine the impurities in the spiritual roots that are harmful to the monks. Therefore, the heat should be moderate. Whether it is higher or lower, it will greatly reduce the quality of the elixir and even be scrapped.

Of course, the higher the elixir refining method, the more complicated it is, and the chance of refining top-grade or even top-grade will be greatly reduced. According to Master Fu Zong, only top-grade elixirs are completely perfect without any impurities.

Therefore, the longevity prolongation pill requires that it must be a top-quality pill, otherwise it will not only not prolong life, but also may shorten the lifespan of the monk.

The life span of a monk is not completely fixed. Just like a human, the life span of an ordinary person is eighty to one hundred years old. Even if it is not considered a death from an illness, there are also hidden diseases, weak constitutions, etc., which lead to different life spans.

The same is true for monks. Taking pills with lower grades will not only make it more difficult to advance in the future, but will also greatly reduce the lifespan of monks. Just like ordinary people who are overworked every day, once they are old, various hidden diseases will appear, and their lifespan will be less than that of ordinary people.

In general, monks who have entered the transcendent realm have twice the lifespan of ordinary people, which means they can live to 200 years old. Of course, some monks who have good health and have never taken pills have lived to 250 years old.

On the contrary, if you take low-grade pills multiple times, it is very likely that a monk in the Transcendent Realm can only live to 120 to 140 years old, and his life span is greatly reduced. This is an indisputable fact.

Therefore, the importance of the grade of the longevity elixir and various elixirs is reflected. The longevity elixir can extend the lifespan of a cultivator. It is said that those high-level longevity elixirs can even make a person's lifespan reach its limit!

The lifespan limit of an ordinary person is no more than 250 years old, which is comparable to a super strong person in the transcendent realm. This is the limit. No matter how powerful the longevity prolongation pill is, an ordinary person cannot live to 250 years old.

The maximum life expectancy limit of the Transcendent Cultivator is no more than 500 years old. In other words, even the powerful longevity prolongation pill can only allow the Transcendent Cultivator to live to 499 years old, because five hundred years old is the life span of an invincible strong man who is transcendent.

A strong man who is transcendent in the realm can live to five hundred years old. This life length can be called a monster in the human world. Therefore, in the eyes of many people, the monk who is transcendent in the realm is an old monster.

The limit of the transcendent realm is that of a thousand years. The transcendent realm can only live to 999 years at most. This can only be achieved by the longevity-extending pill with almost the heavenly effect. Otherwise, ordinary transcendent realm strong people can only live to 500 years old.

As for a thousand years, that is the life span of people in the heavenly realm.

In this world, although there is a man of underworld, there is no reincarnation. Once the life span of a monk is exhausted, it is eternal death. Legend has it that if a person is strong enough, his body and soul after death will be reborn in the mansion and live for another lifetime, and will be boundlessly powerful!

But this is just a legend and no one has seen it. Moreover, even if you can be reborn in the underworld, it will be reborn for a lifetime. Once your life span is here, your soul will still be scattered!

Therefore, the longevity pill has become the most precious thing among monks because it represents life span! However, the longevity pill is extremely difficult to refine, and the materials are rare, so the value has always been in price but not in market and the supply is in short supply.

Li Xiao took a deep breath and could buy the materials for the longevity pill. Even if it is expensive and scarce, it would not be cut off. However, the success rate of elixir refining is too low. It would be good to refine one furnace of 100 furnaces of longevity pills. This is only possible for a few alchemy masters in China. For an ordinary alchemist, even if you give him a thousand furnaces of elixirs, he would not be able to refine it.

With his amazing memory, Li Xiao wrote down the steps of refining marrow cleansing pill step by step, forcibly wrote it down, and then analyzed and implemented it in his mind.

For a whole day, Li Xiao did not start to refine elixirs, but was sorting out his thoughts.

Master Fu Zong did not urge him either. Looking at Li Xiao's movements, there was a look of appreciation in his old eyes.

On the second day, Li Xiao's eyes suddenly opened and began to refine the pills. Master Fu Zong lived with a large number of spiritual roots, and these low-level spiritual roots were not valuable, so he was not afraid of Li Xiao's waste.

The seal in his hand was slapped out one by one with Li Xiao's memory and fell into the alchemy furnace. Three hours later, the cauldron lid was lifted and a pungent smell came.

"The lowest elixir!"

This furnace is worse than the furnace commanded by Master Fu Zong. There is no way. There was a master in front of him, so Li Xiao didn't need to think at all, but now he is refining it himself and is completely incomparable.

Shaking his head, Li Xiao continued to refine the alchemy.

Three days later, the medium-grade marrow cleaning pill was officially released.

Seven days later, ten days in total, the first furnace of the top-grade marrow washing pill was released.

At this moment, Old Man Fu Zong was really scared. Not to mention the speed of improving the quality of the alchemy, Li Xiao’s alchemy has a characteristic. If the middle-grade elixir is produced, then the later refining will basically be medium-grade elixirs, and few low-grade elixirs appear.

And the best elixirs are produced, and the same is true. Medium and low elixirs rarely appear again, and they are basically top elixirs!

Thinking of this, Old Man Fu Zong secretly thought that if the success rate of the best elixir is still like this, then wouldn’t Li Xiao make a big profit?

Until the twenty days passed, the elixirs refined by Li Xiao still only had the best grade, and there was no furnace of top grade pills yet.

At this moment, Fu Zong, who was sleeping in a fragrant manner at the stone table at the door, woke up in a daze, barely opened his hazy old eyes, but looked outside the yard.

"Master Fu Zongzi is here? Luo Cheng, the elder of Xiatianyu Immortal Sect, asked for a meeting."
