Chapter 1385

Although Dragon Shedding Grass and True Dragon Blood were rare herbs, the Heijia family had been in control of the herb market for many years. It only took them a day to gather a hundred sets of ingredients.

According to the elders of the Heijia family, this kind of ancient pill would be difficult to refine and the success rate would be very low. In addition, Gu Ding did not have any experience in refining this kind of pill. He would have to go through all kinds of adjustments in the early stages. He would need at least thirty to forty practices before he could succeed.

According to their calculations, Gu Ding would be lucky if he could refine ten out of a hundred sets of ingredients. Even with the standards of the Founding Elders, after looking at the pill recipe, they estimated that out of 100 sets of materials, they could at most refine 20 sets of finished products.

Through the elders' authority, Gu Ding requisitioned the best alchemy furnace in the Heijia family.

It was said that the alchemy furnace was brought out from an ancient ruin. The Heijia family had spent a lot of money to buy it back then.

Entering the alchemy room, Gu Ding immediately saw a huge alchemy furnace that was more than three meters tall. It looked like it was made of ancient bronze and was dark brown in color. The patterns on it were complicated and there were even carvings of ancient beasts.

Gu Ding could even faintly feel the aura of the Great Path from the alchemy furnace. He could not help but raise his eyebrows as he turned to look at the elders. "This alchemy furnace …"

"It's an ancient Great Path alchemy furnace. It contains the Great Path." The elder at the back nodded. He knew what Gu Ding wanted to say.

"Thank you. This way, the quality of the pills refined will increase a lot." Gu Ding nodded in satisfaction. He was considered a pill refiner now. It was natural for him to be tempted by such an alchemy furnace. Using such an alchemy furnace to refine pills would probably make one feel much happier.

"The herbs are all in this storage ring. We have already sorted them out." The elder walked forward and handed a storage ring to Gu Ding.

Gu Ding took the ring and looked through the herbs. He could not help but sigh in his heart. The Heijia family was indeed a medical family. In the storage ring, the herbs were not only sorted but also placed according to the order in which they were placed. Not only that, the one hundred sets of medicine were precisely divided. All he needed to do was to place them at the right time.

Of course, alchemy was not that simple. There were many details that determined the quality of the pills.

There were only Gu Ding and the five members of the Heijia family in the alchemy room. After closing the door, the five elders retreated to the wall.

Gu Ding took a deep breath, adjusted his state of mind a little, and began.

Once the fire in the alchemy furnace was ignited, Gu Ding immediately began.

This scene caused the five Grand Elders to be somewhat puzzled.

"He is just warming up the pill furnace. Why is he using the fire-controlling hand seal so early?" The Third Elder could not help but mutter.

"Maybe he's trying to familiarize himself with the Fire Control Handprint that he's going to use later." The Second Elder couldn't think of a better explanation.

At that moment, Gu Ding opened his mouth. "Actually, it's not that I'm familiar with the Fire Manipulation Handprint. I'm using a very simple Fire Manipulation Handprint now, but it'll be much more complicated when I'm refining pills later. Now that I'm controlling the fire, one is to familiarize myself with the operation of the entire pill furnace, and the other is to explore the effects of different heating points. "

Seeing that Gu Ding was distracted in his explanation, the two old men's faces turned red. They did not say anything else and just watched quietly. They had been refining pills for many years, but this was the first time they had heard Gu Ding say something like that. The preheating they had learned before was just a simple preheating. As long as the furnace was preheated to a certain temperature, they could officially start putting in the herbs for refining pills. Little did he know that a simple warm-up had so many things to it.

The alchemy furnace heated up for about a quarter of an hour. Gu Ding could feel the temperature inside the alchemy furnace. He reached out and opened the lid of the alchemy furnace.

After putting the first medicinal herb into the furnace, he covered the furnace lid.

Seeing this scene, the Eminent Elders were stunned again.

"According to the description of the elixir recipe, there should be three kinds of medicinal ingredients in the beginning, right?" This time, it was the four founding elders who asked.

Gu Ding looked down at the time, then explained without turning his head, "The prescription gives the conventional refining method, which is also the most labor-saving refining method. In fact, almost all medicinal herbs had different melting points at different temperatures. Different medicinal herbs require different amounts of time, and the degree of integration of the medicinal properties is also different. "

"If the elixir recipe wrote down the time of each medicinal herb and the integration of the medicinal properties clearly, I'm afraid a single elixir recipe would become an elixir recipe."

"The reason why several medicinal herbs are put in at the same time is because the melting points of these medicinal herbs are similar. They are only two to three minutes apart. Putting them in at the same time has little effect on the integration of the medicinal properties. The reason why I put the medicinal herbs in separately is because I'm a pharmacologist. When I refine medicine, I have to be precise down to the microsecond. I also have to be precise with the weight of the medicinal ingredients down to the microgram. However, when it comes to the elixir, I can only be precise down to the microsecond. If I want to be more precise, I need to refine it many times. However, the ingredients for this Dragon God Pill are rare and limited, so there's no way to refine it. "

As Gu Ding spoke, he moved the lid of the furnace again and put in the second medicinal herb. However, he did not close the lid. After about thirty seconds, he put in the third medicinal herb.

"My young friend Gu Ding, how do you know the melting points of different medicinal herbs and the degree of integration of their medicinal properties?" The Elder Yuan looked like he was asking for advice.

"I don't know the melting points of all the medicinal herbs and the degree of integration of their medicinal properties. I just slowly summarized them after refining in the Virtual Alchemy Lab. For example, in this elixir recipe, there are five medicinal herbs that I've never come into contact with before. I have no idea about the medicinal properties of these five medicinal herbs in practical use, let alone the melting points. Therefore, I can only experiment a few times to see what quality of elixir I can refine, and then adjust it again and again. "

Gu Ding's explanation made the elders feel ashamed. When they refined elixirs, they usually followed the elixir recipe exactly. If the success rate was low, they might find a way to adjust the method of refining. If the success rate was not low, they would not continue to study how to improve the elixir recipe and refine higher quality elixirs.

According to Gu Ding, that was exactly what he was doing. He was constantly improving the elixir recipe based on what he had learned and his own experience.

The five elders originally just wanted to watch Gu Ding's refinement to avoid similar failures in the future. They did not expect to learn something different from Gu Ding. The five of them finally started to get serious. At the same time, they started to look forward to the quality of the elixir Gu Ding refined.

The Second Elder took out the Memory Crystal and began to record Gu Ding's refining process.
