Since the most critical preparations at the moment have been preliminarily confirmed by Ding Zhengyi, then he will not delay any more time in the future.

After carefully combing through the relevant records about brewing medicinal wine, I saw Ding Zhengyi rubbing his chin and doing a little scrutiny, as if he nodded with understanding, and then he began to work step by step.

The first thing is to mark the exact location of the Bixin tree in front of you, and use this as a reference point to dig a cave that points directly to the center of the tree, which is used to store the raw materials of the prepared spirit wine, so that time can give birth to qualified medicinal wine.

This step seems to be very easy, but in practice, it is very difficult.

Just requiring the cave to be able to reach the depths of the heart of the tree, and not affecting its normal growth, made many low-level cultivators helpless, and it seemed to verify the old saying often said in the cultivation realm, simple but not simple.

For ordinary Qi cultivation period cultivators, letting them use sharp magic weapons to cut down or destroy this thousand-year-old spirit tree would only result in a slightly larger consumption of vitality at most, and the consumption of physical energy would be almost negligible, which was not a difficult task.

However, if you want to accurately grasp the scale, especially without affecting the root of the Bixin Tree, and dig out the tree hole from the extremely strong trunk, then with the strength of an ordinary Qi cultivation stage cultivator, it will be difficult for some strong people.

However, this made it difficult for most low-level monks to start, and it was simply a breeze for Ding Zhengyi, who was already a master of flesh and skin in terms of forging and had a thousand catties of great strength.

At this time, I saw him groaning for a moment, and then with Ding Zhengyi's confident expression, he casually took out a medium-grade magic weapon long sword from the storage bag.

Gently weighing the "trophy" snatched from Sanxiu's hand, the cold glow on the sword body that wanted to be hidden, against the backdrop of a large number of flint lights on the top of the mountainside cave, penetrated Ding Zhengyi's eyes, which seemed to make the sense of confidence on his face stronger.

Then Ding Zhengyi did not mobilize his own vitality to stimulate this medium-grade magic weapon with five mana marks, but directly used his steel tong-like fingers to slowly clamp the sword spine, and then moved his hand without thinking.

When screening the Bixin tree in large quantities just now, Ding Zhengyi had already carefully sensed the tree in front of him, inside and out, and at this time, its internal structure and texture were almost meticulous in his mind.

Therefore, its carving and chiseling action can be described as free, and at the same time as the cold light of the long sword flashes, the bark and trunk of the Bixin tree and other fragments are flying and falling everywhere, making Ding Zhengyi like an ordinary carpentry master, and the overall performance is very easy.

In less than a cup of tea, a three-inch smooth tree hole that leads straight to the heart of the tree, which can be called flawless, was carved in Ding Zhengyi's hands, if he hadn't taken into account the loss of vitality of the Bixin tree, and tried his best to avoid hurting its roots due to rough techniques, then it could have been faster.

After all the sawdust around him settled, Ding Zhengyi carefully checked it again, until he confirmed that there was no mistake, he breathed a sigh of relief, and put down the medium-grade magic weapon long sword in his hand.

However, although this crucial step was completed, Ding Zhengyi did not have any intention of resting, and at this time, he was quite excited, and he seemed a little passionate, so he quickly took out the small wine pot given by his father Ding Zhongyuan.

After sensing that there was about half a catty of Yellow Tooth Spirit Wine in the wine jug, Ding Zhengyi didn't care to taste the spiritual sustenance left by his father on the wine jug, and saw that he immediately took out two silver silk grasses and three moire grasses from the storage bag in his arms.

The recipe for brewing medicinal liquor recorded in the stone wall of Lingquan is described in great detail, and the quality and dosage of spiritual liquor corresponding to each spirit grass have strict requirements.

It is like brewing the silver silk medicinal wine used by monks in the late stage of qi training, it is made of one pound of yellow tooth spirit wine, corresponding to four silver silk grasses, and then matched with six moire grasses in the foundation building period, such a proportion is the most suitable.

As for why this is so, Ding Zhengyi is currently incomprehensible, but if there is a wrong match, he is very clear.

If there is too much spirit wine, it is fine, but in the worst case, the effect of the same amount of medicinal wine will decrease, but the total amount of medicinal effect will not change, and this will not bring additional side effects.

However, if the spirit wine is insufficient, it will be difficult to completely remove many impurities in the main medicine without its abundant dispensing, and the consequences obtained from this are nothing more than two, either the quality of the medicinal wine will be greatly reduced, and its effectiveness will be greatly reduced, or it will become a "poisonous wine" that cannot be taken by monks, and it is almost worthless.

This is just the first time to try to brew medicinal liquor, and it is far from the time to forge ahead and find out the roots.

Ding Zhengyi, who has always been cautious and cautious, will never do the reckless move of the newborn calf who is not afraid of tigers, let alone advance in the face of difficulties, verify whether the proportion of raw materials is appropriate in ignorance, and thus try to fail.

Therefore, strictly according to the recipe is the best choice at this time.

After a little weighing in his mind, Ding Zhengyi didn't continue to think about it, and then he lowered his head, and in anticipation, his gaze slowly swept over the five spirit grasses in his hand.

Two slender silver silk grasses, full of bright threads, and three flat and handsome, smooth and even moire grasses, from the appearance of the verdant dripping, full of charm.

Although the silver silk grass is only the main medicine in the qi training period, its preciousness is obviously more rare than that of the auxiliary medicine moire grass in the foundation building period.

At this time, in Ding Zhengyi's eyes, the appearance of the silver silk grass is also deeper and more introverted, mellow and dense, showing an extremely extraordinary meaning, if it is a fine induction, he seems to be able to smell the unique fragrance of the main medicine.

Carefully stroking these five spirit grasses that are quite valuable and can also be found, Ding Zhengyi slowly pursed his lips, obviously his heart was quite hesitant.

This can't be blamed for his bad mood, thinking that back then, when Ding Zhengyi practiced drawing talisman seals, he only lost a few spirit stones worth of talisman making raw materials, which would make him feel distressed.

Comparatively speaking, at the moment, Ding Zhengyi spent hundreds of spirit stones on his first attempt to brew medicinal wine, in case there were some twists and turns in the middle, and the loss of goods was still secondary, the blow to his confidence was really not to be underestimated, so it was not surprising that he was a little nervous now.

However, although Ding Zhengyi has always planned and then acted, and does not do things that he is not sure of, since he has made up his mind to try, indecision is not his style.

After a moment's effort, the slight hesitant expression on Ding Zhengyi's face was replaced by an abnormal firmness, and then his body shook slightly, and a scorching breath gradually emitted from his palm, slowly enveloping all the five spirit grasses.

Before brewing medicinal liquor, the importance of the pretreatment of the spirit grass is almost exactly the same as the selection of the Bixin tree, which is not only related to the quality of the medicinal liquor, but also determines the success or failure of the brewing.

Of course, Ding Zhengyi didn't dare to be careless about this, he was cautious, concentrating on controlling the operation of the vitality in his body, constantly adjusting the temperature of his palm, judging from his cautious expression, it seemed that he was much more cautious than when he practiced qi.

According to the records on the stone wall of Lingquan, after the spirit grass is evenly heated, it will greatly increase its intrinsic medicinal activity, increase the transformation efficiency of storage, and greatly reduce the consumption of time.

This process is almost the same as alchemy, but the difficulty is very different, which is also the direct reason why Ding Zhengyi still dares to try it directly without any foundation.

Of course, even if he had limited knowledge of this, he still seemed to stumble a little at the beginning of the operation, but this did not prevent him from following the plan, so he slowly did a good job.

In less than half a cup of tea, under the double "gaze" of Ding Zhengyi's gaze and divine sense, the five spirit grasses in his hands quickly withered under the action of heat, and finally turned into a crumpled appearance, no longer as brilliant as before.

But this seemingly dilapidated transformation did not make Ding Zhengyi show worry, but his calm face gradually showed a smile that could not be concealed.

Up to now, all the methods used by Ding Zhengyi to deal with the spirit grass are very handy, and those controls that are still somewhat difficult have been easily resolved by him one by one, and now the vitality in his body is running, it is simply like a fish in water, and it is easy.

Maybe this is related to the fact that Ding Zhengyi's divine sense is already strong, and at the same time he has the foundation of talisman and array, but he doesn't know why, and at such a critical moment, he doesn't have the time to make more guesses, so he can only ignore it helplessly.

As the shape of the spirit grass gradually took shape, there was almost no change, and the smile on the corner of Ding Zhengyi's mouth became more and more serious.

After a while, I saw that after he nodded in satisfaction, he gently shook his hand, and his flexible fingers slowly kneaded and pressed against the five spirit grasses in his palm.

This kneading process is to destroy the tissue structure of the spirit grass so that its medicinal power can be better released, so as to increase the speed of the transformation of the medicinal wine.

Although in this process, Ding Zhengyi's movements looked a little stiff and obviously not very skilled, but fortunately, he is now successful in forging his body, and his control of strength is extremely accurate, so he barely made a mistake.

With the passage of time, the few spirit grasses in Ding Zhengyi's hands gradually turned into a dark green mass of gel, no longer returning to their original shape.

In this way, step by step, in the next half an hour, Ding Zhengyi continued to complete a series of necessary steps for brewing medicinal liquor, such as vitality nourishment, sealing and isolation, and sealing and filling tree holes.

Even if Ding Zhengyi may still be unclear and vague in some places, this does not affect his meticulous and strict implementation of the requirements, and he has not the slightest sloppy and perfunctory intention from front to back, and strives to achieve excellence from the inside out.
