Immortal Palace Longevity

The spirit herbs required for the Juling Pill in the early stage of Qi Refining are only six, the spirit herbs required for the Qingling Pill in the middle stage of Qi Refining are seven, and the spirit herbs required for the Ziling Pill, an ordinary pill in the late stage of Qi Refining, are nine.

The spirit herbs required for the Biling Pill are two more than those for the Ziling Pill, reaching eleven, and the spirit herbs required are also older, consuming more spiritual power.

After scattering one hundred spirit stones and ripening them for seven or eight hours, Liu Yu obtained thirty-five portions of spirit herbs for refining the Biling Pill, plus the original five portions, a total of forty portions of spirit herbs.

This ratio is much lower than that of the Juling Pill and the Qingling Pill. It seems that more and more spirit stones will be consumed in the future. As the age of the spirit herbs increases, more and more spirit stones will be consumed, Liu Yu concluded.

The seeds were put in a wooden box and placed in the cabinet of the cabin on the left.

After Liu Yu sorted out the three wooden houses, they were no longer messy. The medicine cabinets in the small wooden house were neatly arranged, and the wooden boxes containing seeds were placed in the cabinets in different categories. The name of the seeds was engraved on each wooden box, making it easy to find.

After Liu Yu put the seeds away, he sent the spiritual medicine to the outside world in batches several times, and packed it in the jade boxes that had been prepared in advance to preserve the medicinal power.

After the soul left the immortal mansion, Liu Yu took out the booklet that recorded the experience of alchemy. With the increase in the number of times of alchemy, this booklet recorded many experiences and conjectures, as well as the problems encountered in the process of alchemy. The dense handwriting has already written a small half of the booklet.

Looking at the thick alchemy notes, Liu Yu felt a little sense of accomplishment in his heart. This was the proof of his step-by-step learning of alchemy, and witnessed his growth in the way of alchemy.

Starting from the first page, he flipped through the experience, reviewed the old and learned the new, and stopped at a page in the middle.

This page records a fire control array that Liu Yu recorded from the sect's Sutra Pavilion. It is much more advanced than the fire control array recorded in "Basics of Alchemy". The temperature of the flame is higher, which can melt the spiritual medicine of older age faster and make it lose less medicinal power.

The fire control array recorded in "Basics of Alchemy" is only the most basic after all, and the temperature of the flame is not high in comparison. As the grade of Liu Yu's elixir refining increases, it is extremely difficult to use it.

The fire control array recorded in the Sutra Pavilion is called the Red Flame Array, which is much more complicated to arrange.

Liu Yu emptied all the items in the room next to the left, and this room will be used as the alchemy room in the future.

He held the booklet in one hand and carefully carved the Red Flame Array on the ground according to the record above. It took half an hour to complete the carving.

The flame temperature of the Red Flame Array is much higher, so it naturally consumes more spiritual power. It takes five spiritual stones to activate the array.

Put five spiritual stones on the five nodes of the corners of the red flame array, take out the purple Xuan Ding, open the fire door below and place it in the center of the array, put a spiritual herb for refining the Green Spirit Pill beside him, and the preparation for refining the pill is complete.

Liu Yu waved his hands and cast a series of spells on the array, and the array immediately lit up red, the inlaid spiritual stones lit up, and the spiritual power began to run and consume.

In the center of the array, a small red flame emerged from the bottom of the purple copper tripod, gradually growing to the size of an adult's fist, and burning fiercely in the fire door. Unlike the fireball technique, the flame stimulated by the red flame array is extremely stable and relatively gentle.

For a while, the air in the room was filled with blazing high temperature, and the room temperature rose rapidly, causing Liu Yu, who was standing next to him, to sweat on his forehead.

Liu Yu cast a spell from time to time, which landed on the red flame array, adjusting the frequency of fire output and controlling the stability of the flame.

After about half a quarter of an hour, the flame of the formation gradually reached the most stable state, and the Purple Profound Cauldron was almost preheated.

Knowing that the time had come, he began to put the spiritual medicines in order according to the records on the pill recipe.

Although Liu Yu's alchemy level was no longer the same as the first time he made an alchemy, the difficulty of refining the first-grade top-grade Biling Pill was not comparable to that of the first-grade low-grade Juling Pill. The spiritual herbs used were almost doubled.

Looking at the black and sticky things in the Purple Profound Cauldron, the first time he refined the Biling Pill was undoubtedly a failure. After cleaning up the impurities in the Purple Profound Cauldron, Liu Yu started the next batch of refining.

Eight days passed in a flash. During these eight days, Liu Yu refined five batches of Biling Pills every day. After all the forty spiritual herbs were consumed, he finally succeeded in only three batches and obtained twenty-nine Biling Pills.

The success rate is less than 10%. Although he had expected this result, Liu Yu still smiled bitterly and felt helpless. Although his powerful spiritual consciousness gave him some advantages over ordinary cultivators in alchemy, it was also extremely limited. He mainly relied on the low cost of the spiritual herbs produced by the Immortal Palace and could practice a lot.

The success rate of less than 10% actually had a lot to do with Liu Yu's direct refining of first-grade top-grade elixirs. He had a success rate of 30% to 40% in refining first-grade middle-grade Qingling Dan before, but the difficulty of refining first-grade top-grade elixirs directly increased suddenly, and the success rate was of course much lower.

One portion of the spiritual herbs for refining the Biling Dan was worth 20 spiritual stones, and 40 portions were 800 spiritual stones. Calculated at the market price of 8 spiritual stones for one Biling Dan, 29 were 232 spiritual stones, a full loss of 568 spiritual stones.

I'm afraid that some medium-sized sects can't afford this kind of loss, and some small immortal cultivation families will be seriously injured. Only Liu Yu, who has the immortal palace as a support, can accept it without feeling any pain.

If you take it step by step and refine the first-grade purple spirit pill first, the success rate will never be so low.

But the situation is urgent, Liu Yu doesn't know how long his peaceful cultivation life can last. He might encounter a powerful enemy one day, so of course he has to race against time to improve his cultivation!

The materials for the forty Biling Pills have been used up, and the matter of refining the pills has come to a temporary end.

Since he has the Biling Pill, Liu Yu will certainly not continue to use the inferior Ziling Pill for cultivation. From then on, he takes the Biling Pill every day to feel the pleasure of rapid improvement in cultivation.

In addition to taking the Biling Pill to meditate and refine Qi every day, Liu Yu has not given up the practice of spells and magic tools.

Especially the Hidden Spirit Art obtained from the "Magic Cultivation Essentials", he has to study and practice it every day. Liu Yu attaches great importance to this secret art that can hide his cultivation and restrain his breath. Although he will not use it to kill or set fire, if he encounters an enemy, restraining his breath and hiding his traces at a critical moment can often play a role of surprise, and I believe it can have a miraculous effect.

It's a pity that the Hidden Spirit Art is obscure and difficult to understand. I have been practicing diligently for several years since I got this secret art, but it is still a long way from the second level.

He often took out the two new magic weapons, the Mother and Child Soul-Chasing Blade and the Black Iron Shield, to practice and familiarize himself with them. After a period of practice, he could use the two magic weapons freely and they had completely become part of his strength.
