Chapter 5: Refining Dan Medicine
Du Feiyun stayed in his room for the entire afternoon and didn't come out until dinner time.
Just as he put down his rice bowl, Du Feiyun hastily left the dinner table and ran to the woodshed in the courtyard where various sundries were stored. He rummaged out many dried herbs, then carried these herbs back into the house with an air of mystery, closed the door behind him and didn't come out again.
Seeing this scene, Du's eyebrows were raised, and she couldn't guess what the kid was up to. Du Qing, who had been absent-minded all along, also sensed something unusual about Du Feiyun, and the two of them looked at each other in dismay, both somewhat perplexed.
In the quiet and dimly lit room, a bean-sized oil lamp emitted a faint yellow glow. Du Fei Yun sat cross-legged on the bed, one hand flat on his leg, the other supporting the bottom of the Nine Dragon Cauldron floating in front of him. On one side of the bed, a low table held numerous herbs cut into fine pieces.
At this time, the Nine Dragon Cauldron was almost twice as large as it appeared at noon, and it was a foot high. The nine black dragons carved on the cauldron were more vivid and dynamic than before.
Du Fei Yun's eyes were fixed intently on the Nine Dragon Cauldron, his right hand supporting the bottom of the cauldron was continuously transmitting the yuan force from within his body.
His strength was only at the fourth layer of the Refining Body stage, and the yuan force accumulated in his body through cultivation was also very weak. The yuan force that flowed out was as thin as a strand of hair, and it would be depleted within half an hour at most. Once the yuan force in his body was depleted, his body would become extremely weak, and to recover, he would need at least ten days or half a month of bitter cultivation.
As a cultivator, Du Feiyun naturally knew this principle, but at this moment he was still pouring his internal yuan into the bottom of the Nine Dragon Cauldron without hesitation. Everything, just because, he was preparing to refine the elixir!
Yes, that's right, he is indeed preparing to refine the elixir!
Originally, only cultivators who had reached the Xiantian stage could stimulate the majestic yuan force within their bodies to surge out and form a yuan force true fire to refine dan medicines.
But just this afternoon, he carefully comprehended the alchemy method recorded in the Jade Book and finally discovered that if he tried according to the secret method of elixir recorded in the Lietou Medicine Classic, he could also use the secret method in the Lietou Medicine Classic to release his internal yuan force externally, thereby meeting the basic conditions for refining dan medicine.
Seizing this glimmer of hope, Du Fei Yun boldly made an attempt, and the result was naturally exciting. He found that he could actually mobilize the yuan force in his body and transmit it through his right arm to the base of the Nine Dragon Cauldron, which had countless mysterious tracks and patterns engraved on it.
What happened next was even more astonishing to him. He found that when his yuan force entered the bottom of the Nine Dragons Cauldron, which was about the size of a palm, the cauldron actually underwent a subtle change. The nine black dragons carved on the body of the cauldron became even more vivid and dynamic, and the temperature inside the cauldron began to rise gradually!
It originally required the congenital boundary to refine the elixir, but he only had the body-refining period strength and could also refine the elixir. The excitement in his heart can be imagined.
According to Yu Jian, taking elixirs can make one intelligent and young forever; long-term consumption can lead to eternal life.
Although he didn't dare to hope for eternal youth or immortality, he understood that if he could refine the elixir and take it, his strength would definitely increase rapidly! With great power, he wouldn't have to fear the Qin family's revenge and could protect himself and his loved ones.
The jade tablet also clearly states that the way of cultivation requires gradual progress, daily hard work, breathing and taking in the spiritual energy of heaven and earth to temper oneself, and only by doing so can one's strength be truly solid and stable.
Taking Dan medicine can advance quickly, but it will cause the foundation to be unstable. In severe cases, there is a risk of falling into evil demons and destroying one's cultivation.
But what Du Fei Yun needs most urgently now is to rapidly increase his cultivation strength in the short term! Only with enough powerful strength can he protect himself and his loved ones. So, when he learned that he could also refine Dan medicine, the joy was overwhelming.
Although he didn't understand why his physical body could refine the elixir, he knew that this small cauldron must have a very magical and special effect, which allowed him to complete the refining of the elixir with his physical body strength, something that only a pre-heavenly cultivator could accomplish.
Having proven the feasibility of alchemy, Du Fei Yun naturally couldn't wait to experiment. He carefully flipped through the Leshan Pharmacopoeia, wanting to find a kind of elixir suitable for his own refining and taking.
Those who can refine elixirs are all cultivators above the Innate Period realm, and the refined elixirs are also for powerful cultivators to take. As for those in the Refining Body and Refining Qi periods, they probably don't have the qualifications to take those spiritual elixirs yet.
Usually, cultivators in the Refining Body and Refining Qi stages who want to rapidly increase their strength will choose to take highly nourishing medicines or heavenly materials and earthly treasures, such as several decades old He Shou Wu or hundred year old ginseng.
As the saying goes, "Hard work will not betray those with a sincere heart." After carefully searching and looking for a long time, Du Fei Yun finally found a suitable elixir among thousands of prescriptions that he could take.
Rebirth Bone Dan!
This is the lowest level of Dan medicine recorded in the tens of thousands of Dan formulas in the Lièshān Medicine Classic, suitable for all practitioners below the Pre-Heavenly Boundary to take, and even ordinary people who have not yet set foot on the path of cultivation can take it without harm.
The medicinal effect of the elixir is as its name suggests, whether it's a cultivator or an ordinary person who takes this Rebirth Elixir, they will quickly be cleansed of their meridians, strengthened in sinew and bone, tempered in tendons and marrow.
After taking it, those who were unable to cultivate can have their meridians widened and be able to step into the path of cultivation. Those who are already cultivating can make their tendons and meridians even more resilient, advancing their strength even faster.
As he continued to input yuan force into the Nine Dragon Cauldron, the temperature inside the cauldron had risen to a suitable degree, and he knew it was time to start.
His right hand remained still, attached to the bottom of the small tripod, as he channeled yuan energy into it. His left hand quickly lifted the eight-sided lid of the Nine Dragons Tripod, and a scorching yet calm aura rose from within.
Although this was his first attempt at refining the elixir, he had already memorized the secret method of refining medicine recorded in the Lièshān Medicine Classic. As he silently recited the method, he carefully executed each step.
His left hand shot out like lightning and quickly put the herbal powders on the table into the cauldron one by one, without any difference in order.
"Golden needle mushroom one tael, seven-colored flower two taels, silver moon fruit one tael, five-leaf irises one tael..."
Murmuring the recorded dosage and sequence of herbs in Dan Fang, Du Fei Yun quickly put all the materials for refining the Tái Bì Huàn Gǔ Dān into it, then closed the lid, continuing to channel his Yuan force into the small cauldron.
Time slipped away quietly, Du Fei Yun had been tensely paying attention to everything inside the small cauldron, constantly speculating whether he could successfully refine it while not daring to stop inputting his yuan power in the slightest.
In the blink of an eye, Du Fei Yun's originally weak Yuan force was quickly depleted, and the output of his Yuan force grew weaker and weaker, gradually becoming thinner than a strand of hair.
"What's wrong, is it going to fail on the first try?" Du Fei Yun's face looked a bit unsightly, after all, he had spent half a day carefully searching for these materials, and if they failed to refine them, it would be difficult to gather them again.
Moreover, some of these herbs are quite rare and even if one goes to the mountains to collect them, it is impossible to find them in a short period of time. If you buy them at a pharmacy in town, you will have to spend several taels of silver.
In fact, Du Fei Yun didn't know that in this world, alchemists were extremely rare. Moreover, even if one was a qualified alchemist, the failure rate of alchemy would still be very high. Out of ten attempts at alchemy, seven or eight times would end in failure, and only two or three times would succeed.
Since the yuan force is insufficient, I will cultivate and absorb the spiritual energy to transform it into yuan force while refining medicine! As soon as he thought of it, Du Feiyun suddenly had this idea. He acted on his thoughts, closing his eyes to enter a meditative state while continuing to channel yuan force into the small cauldron.
This idea is not to be underestimated! If it were any experienced monk, they would absolutely not dare to try this easily. The outcome of using one's heart and two purposes is either the yuan force being disrupted, causing damage to the meridians, or shocking the five organs and six viscera, suffering heavy injuries, and ultimately being extremely dangerous.
Only a low-ranking cultivator like Du Feiyun, who is ignorant and fearless, would suddenly come up with such an idea and take such action.
Fortunately, Du Feiyun's two lives as a person had a strong and resilient will, although he was using his heart for two purposes, he could barely keep his mind clear and never became confused.
Moreover, he gradually discovered that the Nine Dragon Cauldron seemed to contain infinite yuanqi within itself, which could be condensed into true fire through some special methods. The yuanqi he output was actually only playing a manipulative and guiding role, with no huge consumption.
Even with the power of Dou Fei Yun's body refinement period, even if all his life's yuan force was poured out, it would still be far from reaching the level of condensing yuan force into true fire. The yuan force true fire in the Nine Dragons Cauldron is actually the cauldron itself absorbing and condensing yuan force, Dou Fei Yun only needs to use a weak yuan force to guide and manipulate it.
It was precisely because of this that Du Fei Yun was able to refine pills with his limited Qi Refining stage strength, and he could also cultivate while refining pills at the same time without any accidents.
Everything can be attributed to the magical effect of the Nine Dragon Cauldron, and it can only be said that Du Feiyun's luck is indeed good.
