Chapter 53 Precipitation

In the early stage of Qi refining, the Spirit-Gathering Pill requires only six spiritual grasses, in the middle stage of Qi refining, the Qingling Pill requires seven spiritual herbs, and in the late stage of Qi refining, the common elixir Purple Spirit Pill requires nine plants.

The Bi Ling Dan requires two more spiritual grasses than the Purple Spirit Pill, reaching eleven. The year of the spiritual grass required is also higher and consumes more spiritual power.

A hundred spiritual stones were sprinkled down and it took seven or eight hours to ripen. Liu Yu got thirty-five portions of the spiritual grass for refining the Biling Pill, plus the original five portions, for a total of forty portions of the spiritual grass.

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

Put the resulting seeds in a wooden box and place them in the cabinet in the cabin on the left.

After Liu Yu tidied up these three wooden houses, they were no longer as messy as before. The medicine cabinets in the small wooden houses were neatly arranged. The wooden boxes containing seeds were placed in different categories in the cabinets. Each wooden box The name of the seed is also engraved on it, making it easy to find.

After Liu Yu put the seeds away, he sent the elixir to the outside world in batches in several rounds and packed it in jade boxes that he had prepared to preserve the potency.

After Yuan Shen left the Immortal Mansion, Liu Yu took out the booklet recording the alchemy experience. As the number of alchemy times increased, the booklet recorded many experiences and conjectures, as well as problems encountered during the alchemy process. Less than half of the booklet has been written in dense handwriting.

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

Start reading from the first page, review the past and learn new things, and stop at a certain page in the middle.

This page records a fire control formation that Liu Yu recorded from the Zongmen Sutra Pavilion. It is much more advanced than the fire control formation recorded in "Basics of Alchemy". The flames it stimulates are hotter and can burn faster. Melt elixirs with older ages so that less of their potency is lost.

After all, the fire control formation recorded in "Basics of Alchemy" is only the most basic. The temperature of the flame is not high in comparison. As the level of Liu Yu's elixirs increases, it has become extremely reluctant to use it.

According to the records from the Sutra Pavilion, this fire control formation is called the Red Flame Formation, and it is much more complicated to arrange.

Liu Yu emptied out all the items in the room next door to the left, and this room will be used as an alchemy room from now on.

He held the pamphlet in one hand and carefully carved the red flame formation on the ground according to the records on it. The carving was almost completed in half a quarter of an hour.

The flame temperature of the red flame array is much higher, and it naturally consumes more spiritual energy. It takes five spiritual stones to activate the array.

Place the five spiritual stones on the five nodes at the corners of the red flame array, take out the Zi Xuanding, open the fire door below and place it in the center of the array, and put a piece of spiritual grass for refining the Bi Ling Pill beside you Next, the preparations for alchemy were completed.

Liu Yu waved the spells with both hands and hit several magic spells on the magic circle. The magic circle then lit up with red light, the inlaid spiritual stones lit up, and the spiritual power began to be consumed.

In the center of the array, a small red flame emerged from under the copper cauldron. It gradually grew to the size of an adult's fist and burned fiercely in the fire door. Unlike the fireball technique, the flames triggered by the red flame array were extremely stable and relatively mild. .

For a moment, the air in the room was filled with blazing heat, and the room temperature rose rapidly, causing Liu Yu to start sweating on his forehead.

From time to time, Liu Yu would shoot a spell and land on the red flame formation, adjusting the frequency of fire output and controlling the stability of the flame.

In about half a quarter of an hour, the flames of the formation gradually reached the most stable state, and the Zixuan Cauldron was almost warmed up.

Knowing that the time had come, he began to put in the elixirs one by one according to the records on the elixir recipe.

Although Liu Yu's level of alchemy is no longer comparable to that of his first alchemy, the difficulty of refining the first-level top-level Bi Ling Dan is not comparable to that of the first-level low-level Ling Gathering Pill. The number of spiritual herbs used alone is almost too much. doubled.

Looking at the several black things in the Zi Xuanding, it was obvious that the first refining of the Bi Ling Dan ended in failure. Liu Yu gathered his mood and cleaned up the impurities in the Zi Xuanting, and started the next refining process.

Eight days passed in a flash. During these eight days, Liu Yu refined five furnaces of Bi Ling Dan every day. After all forty pieces of spiritual grass were consumed, he finally succeeded in only three furnaces and obtained twenty-nine Bi Ling Dan.

Calculated, the success rate was less than 10%. Although he had expected this result, it still made Liu Yu smile bitterly and feel helpless. Although his powerful spiritual consciousness had some advantages in alchemy compared to ordinary monks, he still had some advantages in alchemy. It is extremely limited. It mainly depends on the immortal mansion to urge the spiritual grass to be very low-cost and can be practiced in large quantities.

The success rate of less than 10% actually has a lot to do with Liu Yu's direct refining of first-order top-grade elixirs. Previously, he had a success rate of 30 to 40% in refining first-order mid-grade Qingling Pills, but after crossing the first-order The difficulty of directly refining the top-grade elixirs of the first level has suddenly increased, and the success rate is of course much lower.

One portion of the refining Bi Ling Dan spirit grass is worth twenty spirit stones, and forty portions are eight hundred spirit stones. Calculated based on the market price of one Bi Ling Dan, which is eight spirit stones, twenty-nine is equivalent to 232 spirit stones. A total loss of 568 spiritual stones.

I am afraid that some medium-sized sects cannot bear this kind of loss, and some small immortal cultivating families will have to break their muscles and bones. Only Liu Yu, who has the support of the Immortal Mansion, can accept it without feeling distressed at all.

If you take it step by step and refine the first-level high-grade Purple Spirit Pill first, the success rate will never be so low.

But the situation is urgent, and 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 must race against time to improve his cultivation!

The materials for the forty Bi Ling Pills have been consumed, and the process of refining the pills has come to an end for the time being.

Now that he has the Bi Ling Dan, Liu Yu will of course not continue to practice with the second-rate Zi Ling Dan. From then on, he will take the Bi Ling Dan every day and feel the pleasure of rapidly improving his cultivation.

In addition to taking Bi Ling Dan and meditating to refine his Qi every day, Liu Yu also did not put down the practice of magic weapons.

Especially the Hidden Spirit Technique, which he got from "The Essentials of Demonic Cultivation", he had to study and practice it every day. Liu Yu valued this secret technique that could hide one's cultivation and restrain one's breath. Although he would not use it to kill people and set fires, But if you encounter an enemy, condensing your breath and hiding your traces at critical moments can often play a surprising role. I believe it can have miraculous effects.

It's a pity that the Hidden Spirit Technique is difficult to understand. I have been practicing diligently for several years after acquiring this secret technique, but there is still a long way to go before reaching the second level.

The two newly obtained magical weapons, the Soul-Chasing Blade and the Black Iron Shield, are often used to practice and get familiar with. After this period of practice, he can use these two magical weapons with ease and have completely turned into a part of his strength.
