Immortal Palace Longevity

The Chu Kingdom's low-grade magic tools cost about 100 spiritual stones, the middle-grade magic tools cost about 200 spiritual stones, the high-grade magic tools cost about 400 spiritual stones, and the top-grade magic tools cost at least 800 spiritual stones, and they are often out of stock.

The outer disciples of Yuanyang Sect are only issued 5 spiritual stones per month. In addition to the standard magic tools issued by the sect, if you want to buy an additional low-grade magic tool, even if you are frugal, it will take nearly two years to collect this amount of spiritual stones, not to mention the middle-grade magic tools of 200 spiritual stones.

After watching Brother Wu go away, Liu Yu withdrew his thoughts and officially began his cultivation career in the medicine garden.

Liu Yu bought 30 copies of the seeds of the spiritual medicine needed for the Juling Pill and 15 copies of the seeds for the Qingling Pill, spending three and two spiritual stones respectively.

He first brought the spiritual medicine seeds collected from the market into the Immortal Mansion and planted them, and after they were ripened by the Immortal Mansion, they were placed in the jade box that had been prepared long ago.

He used another fifteen spiritual stones to replenish the spiritual power consumed by the black spiritual field, which made him feel painful. At this time, there were only eighteen spiritual stones left in the storage bag, which was seriously shrunk.

Touching the storage bag, Liu Yu took a long breath and felt a sense of urgency to earn spiritual stones.

Liu Yu spent two hours every day taking care of the spiritual medicine garden, weeding and watering the spiritual medicine, and then spent two hours carefully studying the basics of alchemy, recording the parts he didn't understand and thinking about them slowly and repeatedly.

Then he spent an hour practicing spells and magic tools. Immortal cultivators go against the will of heaven to pursue immortality and never avoid killing. In addition to the improvement of realm, magic tools and spells are also an important part of strength. Life is at stake and must not be unfamiliar.

At night, he spent four hours meditating and refining qi, using the rich spiritual energy of the spiritual medicine garden to accelerate cultivation.

The realm of cultivation is the root of everything, and Liu Yu always keeps this in mind.

In the last three hours, it is time to sleep and rest. The cultivators in the Qi Refining Stage cannot stay awake all the time, so they must use sleep to restore the energy they have consumed.

Every day is packed with activities. In such a hard-working day, more than half a month has passed in a flash.

After more than half a month of speculation, Liu Yu felt that he had mastered the basics of alchemy and had some ideas about the refining of the Gathering Spirit Pill, so he began to prepare to refine the Gathering Spirit Pill.

Novices usually start with the easy and then the difficult when learning alchemy, and Liu Yu is no exception.

He plans to start with the Gathering Spirit Pill taken in the early stage of Qi Refining, because refining the Gathering Spirit Pill is much easier than refining the Clearing Spirit Pill, and one less spiritual medicine is used, so it is most appropriate to use it to familiarize himself with the process of alchemy.

From easy to difficult is the necessary process for every alchemy apprentice to learn alchemy. Otherwise, no matter how amazing your alchemy talent is, without this step-by-step process, there is only one way to go, failure.

After cleaning a thatched house and sweeping the debris into the corner, the copper tripod was placed in the center of the room. The conditions were simple at this time, so he had to make do with it for the time being.

Liu Yu first carved a miniature formation next to the copper tripod and placed three low-grade spirit stones at the junction of several lines.

This is a fire control formation recorded in "Basics of Alchemy". It can stimulate the spiritual power in the spirit stone through a special method and turn it into a high-temperature flame, which can shorten the time required for alchemy. Moreover, the flame of the formation burns very stably, which helps to improve the success rate of alchemy.

You know, the success of alchemy depends mainly on the precise ratio of alchemy materials, the time of adding spiritual medicine, the control of the temperature during alchemy, the time of opening the furnace to take the pill, and the technique of alchemy.

There is nothing much to say about the precise ratio of alchemy materials. After countless practices of successive generations of cultivators, they have already figured it out clearly. When refining the pill, just prepare the materials and quantities according to the recipe.

Of course, this refers to ordinary alchemists. A few alchemy masters can also adjust the formula according to the changes in the age of the alchemy materials.

Flame is one of the key factors for the success of alchemy, and its importance goes without saying.

If Liu Yu uses the scarce mana of the fourth level of Qi Refining to stimulate the flame, I am afraid that the mana will be exhausted before the end of the alchemy, and the flame is not so stable, which has a certain impact on the success rate of the alchemy.

Most alchemists use ground fire to refine the alchemy. The ground fire has a higher temperature, is relatively stable, and is extremely long-lasting. It is really a good choice.

Liu Yu does not have ground fire now, so he can only choose to use the formation to stimulate the flame, but it consumes some spirit stones.

The input of spiritual medicine and the time to open the furnace are more of a test of the experience of the alchemist. Without dozens or hundreds of times of refining, it is difficult to achieve precise control.

Alchemy techniques are even more difficult to learn. Each alchemist has his own unique alchemy techniques. When teaching apprentices, they often keep a hand and generally only pass them on to their direct descendants or disciples.

Only a few general alchemy techniques were recorded in the alchemy foundation. Liu Yu was quite helpless about this and secretly decided to collect an excellent alchemy technique.

After everything was ready, Liu Yu opened the fire door under the copper tripod and placed the copper tripod in the center of the miniature array.

Then Liu Yu pinched the spell, and a series of red lights appeared on the array. The array absorbed the red light, and the three inlaid spirit stones suddenly became brighter.

A fist-sized flame emitting high temperature appeared under the copper tripod, gradually growing larger and burning fiercely in the fire door.

Suddenly, the air in the room was filled with hot and high temperatures.

Liu Yu, who was sitting cross-legged next to the copper tripod, felt a wave of heat coming towards him, and had to cast a spell on the array to reduce the output of firepower.

After about half an hour of practice, the purple copper tripod was almost preheated, and the purple-red tripod body was faintly shining with red light. Liu Yu felt an astonishing high temperature.

He knew that the preheating was completed, and hurriedly pinched the magic formula with his hand, and a wisp of magic power was injected into the small tripod. The small tripod trembled, and the tripod cover flew up, revealing the round tripod mouth.

Liu Yu patted the storage bag, and turned his palm, and several jade boxes appeared in his hand, which were exactly the several spiritual medicines needed to refine the Gathering Spirit Pill.

He opened the jade boxes one by one, and according to the pill recipe, he used his spiritual power to absorb one of the spiritual medicines and came to the top of the tripod mouth, slowly entered the tripod, and pinched the magic formula, and the tripod cover flew back and covered the tripod mouth.

Liu Yu's spiritual consciousness probed into the tripod, and his spiritual consciousness carefully controlled the size and temperature of the flame, removing impurities and refining the essence of the spiritual medicine.

After a period of time, Liu Yu continued to pinch the magic formula, according to the requirements of the Gathering Spirit Pill recipe, put one spiritual medicine after another into it, and merged the essence of the spiritual medicine extracted from the tripod into round balls the size of marbles, and began to condense the pill.

As time went by, the small cauldron gradually emitted a hint of medicinal fragrance, which made people feel refreshed.

Liu Yu's forehead was sweating and his face was full of anticipation. He was slightly excited. He moved his fingers and pinched the magic formula, and a white light was shot on the magic circle. The flame slowly extinguished, and his consciousness moved to control the lid of the cauldron to slowly fly up.

At this time, the medicinal fragrance changed. Liu Yu seemed to think of something. He opened it hurriedly and saw a few mottled pills lying at the bottom of the cauldron, which was very different from the usual spirit-gathering pills.

"Second-grade pills?" Liu Yu's face darkened, and he felt a little sorry.

The so-called second-grade pills are a product of the alchemist's failure in refining pills. When there is a slight mistake in the temperature or the time of coming out of the furnace, the spirit of the pill overflows. This kind of second-grade pill contains less spiritual power, and the effect is also minimal.

After calming down, Liu Yu put away the pill, poured out the impurities and powder in the cauldron, and then cleaned it with clean water. After the copper cauldron was completely cooled, he started to make the pill again.
