There is a greenhouse next to the garden, which is extremely dry and suitable for storage. There is a bronze elixir furnace inside the greenhouse, and rows of medicine stands in front of the walls on three sides.

This place will become a elixir house in the future. In ancient times, those who refined alchemy were called alchemists. There are always strong records in the history of all dynasties, and of course they are not so glorious. When emperors seek immortality, alchemists are always irreplaceable. Historical books distort the alchemists as much as possible. The records say that the elixirs they refined contain mercury, which not only cannot make people live forever, but will also take human lives. This has caused ordinary people to have a stronger misunderstanding of the profession of alchemists.

Emperors are all great men of a generation. How could they be deceived by alchemists and take poison pills containing mercury? The way to immortality has existed since ancient times. Looking for alchemists to refine immortality pills is also a respect for alchemists.

There are really elixirs for immortality. But that belongs to ancient times, in that era when flowers contend and numerous magic. As for the earth entering the Dharma-Ending Age, it is impossible to refine such elixirs, but it can be refined with limited resources.

Xuan Qi, who had just broken through the realm, reached the peak of his spirit. A terrifying light flashed in his eyes, and he walked into the pharmacy with dragons and tigers. People could not stand without trust. Since others were asked to find these medicinal materials, they must refine the elixir.

The rich medicinal flavor echoed on the nose, Xuan Qi took a deep breath and felt inexplicably comfortable. The plants and trees have spirits, and they can become medicinal materials of vintage, and they have some spiritual energy.

The old man sighed for a moment and sighed: "It's been so many years since you were born, I have never practiced elixir again. Now I feel inexplicably kind when I see the elixir."

When Xuan Qi heard the old man sighing so much, he didn't say anything. He reached out and pulled out a drawer. Although he wrote hundreds of medicinal materials, not many of them could be used. To refining the longevity and prolonging pill, only seven main medicines and thirty-two medicines were used.

According to Lao Tzu's instructions, Xuan Qi first drew a bucket of well water from the deep well outside. Humans polluted the earth too seriously, and there were many particles floating in the atmosphere. If contaminated water was used to refine alchemy, it would only add a lot of variables.

Even the water produced from the deep well is not something that can be used now. First, use a purifier to purify it, filter out the impurities in the water, and then throw some spirit stone powder into it to fill the well water with spiritual energy. In ancient times, the water in the wilderness had no spiritual energy, and the river flowing above China was not full of spiritual energy.

Put a bucket of water next to the alchemy furnace, Xuan Qi took out fire-attribute jade from the cave heaven. The alchemy cannot be refined with open fire. Some Tongtian Xuan Cultivation will collect underground fire veins and condense three true fires, or five true fires. Xuan Qi has just transformed into true qi and does not have the ability to condense underground fire veins, so this time, he must use fire-attributed spirit stones to arrange magic arrays.

Sitting cross-legged beside the elixir furnace, the three-legged bronze elixir furnace is also an old object of age. It is of complete quality and can still smell a faint fragrance of herbs when it is close. Xuan Qi stretched out his palm and put the elixir aside as if he was light, and then began to carve the magic array on the ground. One by one, the fire-attributed spirit stones were placed into the magic array.

Slow work produces meticulous work, not to mention that a good fire array can increase a great success rate in elixir refining. Whether or not it can be made into elixirs depends on several aspects, such as the purity of the medicinal materials and the dosage of the ratio, the timing of adding medicinal materials, and the method of sacrificing elixirs. Of course, different temperatures also play a key role.

Xuan Qi's cultivation is too low to arrange magic arrays of multiple temperatures, so in this case, Lao Tzu helped to think of a good idea. The temperature of the fire array is arranged according to the highest degree, and different temperatures depend on different altitudes.

For example, if the maximum temperature is one thousand degrees, then when it is raised up, it is eight hundred degrees, and when it is raised up, it is six hundred degrees, and so on, it is used to adapt to different temperature differences using different heights.

Xuan Qi kept these temperatures in mind, and then tried it with the three-legged alchemy furnace. Fortunately, there was a handle on the alchemy furnace, which stretched forward and waved, which complemented each other. He picked up and put down various temperatures and tested it all.

Continue to make the preliminary preparations, Lao Tzu asked Xuan Qi to crush all these medicinal materials and put them into different buckets according to different categories. Because these waters contain spiritual energy, they can remove impurities and refine the medicinal materials. This hand alone allowed Xuan Qi to win at the starting line.

It is a medicine with three parts poison. Why are the pills refined by alchemists in ancient times a great poison? Not only can they not live forever and prolong life, but they will take human life here. They do not have water full of spiritual energy, so they cannot refine the pills for the white bones of the born human beings.

Buckets of potions were placed on the ground in different orders, and the preliminary preparations were finally ready. The old man said to Xuanqi with a serious expression: "Have you smelled the fragrance of the medicinal materials in the elixir furnace?" Xuanqi nodded naturally. It is very rare to have such a strange fragrance in the ancient medicine furnace.

But the old man said furiously: "The guy who uses this elixir furnace to refine elixirs is a slut. Don't he know that different medicinal materials have different medicinal properties. The medicinal properties remaining on the medicinal materials may affect the stability of the next medicinal material. This is a very bad thing. No matter when you reach the end, you must remember that the details determine success or failure. After the alchemy is successful, you must wash it with water."

This... Xuan Qi was a little stunned for a moment. This is a simple and even extremely simple truth. Why didn't he think of it? Different medicinal materials have different medicinal properties. If the medicinal properties in the alchemy furnace are not pure, it will definitely cause the medicinal properties of the elixir. Such simple and simple details are the easiest to be ignored.

After seeing Xuan Qi showing his teaching expression, a smile appeared on the corner of his mouth: "Then start refining alchemy, remember that the whole process is very long. You must keep a normal mind. Nothing can be done overnight..." Whenever this time, the boss always likes to talk.

Xuan Qi nodded and signaled to be taught. He first placed the alchemy furnace on the fire array, then poured in a bucket of spiritual water, injected the true qi into it to activate the magic array. Xuan Qi condensed his true qi and stretched his hands, rubbed the inner wall of the alchemy furnace, and washed the medicinal properties on the four walls of the alchemy furnace. Soon the entire alchemy furnace was washed and completely refreshed.

Under the guidance of the old man, Xuan Qi picked up the first wooden barrel, poured half of the barrel of medicine into it and began to condense the medicine. The elixir was hovering at 800 degrees, using heat to refine the impurities to retain the essence. At the same time, he did not forget to suggest to the old man: "In fact, we can completely quantify the manufacturing, find a container with capacity, and find a constant temperature. Each elixir only refines one elixir..." Xuan Qi became more and more excited: "You can even use computer programming and produce elixirs in assembly lines..."

Hearing Xuan Qi's browsing and romance, the old man had to remind Xuan Qi: "Didn't you smell the burnt smell?"

After Lao Zhu mentioned this, Xuan Qi discovered that the originally green medicine juice in the alchemy furnace had turned black, and the black lump was very ugly.

The old man said to Xuan Qi earnestly: "Everything must be done step by step, and you can also take shortcuts, but you must be thoroughly proficient before you can innovate. Now you are not yet ready to start, but you are thinking about programmatic. Are you too ambitious?"

Xuan Qi lowered his head and received the teachings. What the old man said made a lot of sense. He had no experience in refining elixirs, so he rashly wanted to refine elixirs in a program, which was a bit Meng Lang.

After washing the dark elixir furnace, Xuan Qi poured the medicine juice from the bucket into the medicine cauldron, and then mechanically followed the old man's instructions. The temperature area should be in which temperature area, and the refining techniques should be used. Xuan Qi had no experience in refining alchemy, but after the old man's point, the first furnace of ointment was finally refined.

The green ointment emits a unique fragrance. Xuan Qi has already prepared a small jade box for warming up the raw materials of medicinal materials. He put the ointment into the small jade box and placed it on an empty medicine table in the order prepared by the old man.

The first step in alchemy is to purify the raw materials. After all the raw materials are extracted into the corresponding purity, the formal alchemy begins.

After all the seven main medicines and thirty-two medicines are refined, Xuan Qi has a general understanding of alchemy. Purification of medicines is like a basic skill, or the foundation of a building. Only by practicing the basic skill well and laying the foundation firmly can good elixirs be refined.

With more refined raw materials, the next step is to synthesis of elixirs. The seven main medicines are placed in the elixir furnace in different orders, and then the seven medicinal materials are integrated with different temperatures. The order and timing of putting medicinal materials here are very particular. If the old man did not teach him step by step, relying on Xuan Qi alone, I would probably not be able to find the right method in my entire life.

Then wash the alchemy furnace again and confirm that there are no missing points. When the elixir is at its most critical moment, the thirty-two kinds of medicines are arranged in fourteen rows in different orders. Xuan Qi took a deep breath, and after confirming that it was correct, he began to refine the alchemy.

First put the main medicine into the elixir furnace, and then add the medicine in sequence. As different medicines are added, a strange smell is permeated in the air. This is a strange smell that is difficult to describe in words. It has not appeared in the world for at least many years.

Alchemy and winemaking are similar. Not only should we pay attention to ingredients, but also the heat and timing. Once we miss the opportunity, we may produce completely different things. It is like if wine brewing is wrong, it will turn into vinegar. If the alchemy is made mistakes, it will not be a spiritual object that will prolong life, but a highly toxic waste.

Xuan Qi, who had never refined elixirs, was very concerned about his first work. His whole mind was raised, and his head was covered with beads of sweat the size of soybeans. His clothes had already sweated deeply, and half a foot high white smoke rushed out from the top of his head.
