Seeing Gongsun Yan's nonchalant expression, Gui Dan smiled and asked:
"When you refine the elixir, you probably purify each material separately, right?"
After receiving a positive answer, Gui Danqi continued:
"In fact, purification alone seems to be precise and targeted, but it may not always be effective. It mainly depends on the original formation process of the recipe. If the initial refining process of the recipe is 'one pot cooking', then you must also follow the law.
If treated alone, the 'dissolution' effect will be lost, and the efficacy of the final elixir will often be greatly reduced, or even be counterproductive."
"Therefore, the process of alchemy is not static, nor does it mean that the more steps or the more complicated the process, the better the final result will be. Sometimes too much emphasis on details can be superfluous."
The words were like enlightenment, which made Gongsun Yan suddenly enlightened. He quickly stood up and thanked him profusely, and then continued to observe.
After all the materials were processed and entered the preparation stage, Gongsun Yan observed that Gui Danqi directly mixed various "essences" together, added a drop of "thick juice", and stirred it evenly with a magnetic rod, it immediately turned into a milky white homogeneous phase.
"The most feared phenomenon during the refining process is stratification. This can be avoided by using this thick juice, but you cannot add too much, otherwise too many impurities will affect the efficacy of the elixir."
Gongsun Yan was enlightened, his eyes full of admiration and gratitude.
The process of refining the elixir lasted until noon the next day, and finally the elixir was refined. Thirty pills of each elixir were refined, not a few pills.
Gongsun Yan secretly praised in his heart that he was worthy of being a great master, and the pill success rate was actually 100%! Gui Danqi divided it half and half with him as agreed, and Gongsun Yan got fifteen pills of each of the "Soul Gathering Pill" and "Soul Replenishing Pill"
.
After carefully collecting the elixir, Gongsun Yan asked for advice:
"Grandpa Gui, since the 'soul-gathering grass' can absorb and gather together the souls scattered in space, does this 'soul-gathering pill' also have the same effect?"
"No! But it has the effect of bringing the dead back to life. As long as the person stops breathing within three days and has a physical body, taking this pill can save him or her!"
Gui Danqi continued:
"Actually, the 'Soul Gathering Grass' cannot actively 'absorb souls'. It just passively absorbs souls due to the environment. If it can actively 'absorb souls', wouldn't it be like the 'Soul Summoning Flag', becoming a big killer!"
"
Hearing this, Gongsun Yan's heart moved. There really was a "soul-calling flag" in his ring, which was obtained by killing the Green Humans. He followed Dongguo Huiren's suggestion and seized it when he specifically searched for the Greens and Qings in the "foreign war zone".
.
Gui Danqi then took Gongsun Yan back to the living room. After a while, Yi Rui, accompanied by Gui Yin, also came after hearing the news. When she saw Gui Danqi, she quickly saluted and thanked him.
Not long after, another middle-aged man came in. When Yi Rui saw him, he stood up quickly and introduced to Gongsun Yan that this was Gui Hongshi, Gui Yin's third uncle. Gongsun Yan also quickly stood up to greet him. After a few words of greeting, Gui
Hongshi handed the ring and books to Gui Danqi and left.
Gui Danqi took it and handed it directly to Gongsun Yan and said:
"Well, these are your books. There are also some alchemy books and elixirs that I gave you in the ring. Since you know how to make alchemy, I will also prepare a lot of materials for you on Xuanzhou Continent. You and your wife will return to Qingzhou.
After returning to the mainland, it is not easy to collect these materials. I hope these things can help you. This is all I can do."
Hearing this, Gongsun Yan and Yi Rui came over quickly, bowed respectfully to Gui Danqi and expressed their gratitude.
Gongsun Yan took the book and the ring and found that the interior of the ring was huge. In addition to several rows of elixirs neatly placed on the shelves, there were also many rare materials used to make elixirs, all with labels.
.
Gongsun Yan was greatly moved. After carefully putting them away, he took out a large section of "Yin Vine Grass" and two "Soul Gathering Grass", handed them to Gui Danqi respectfully, and said:
"Grandpa Gui's gift of these things has been of great help to the two of us. I have nothing to do in return. I can only use these two things to honor you when you grow old. I hope you can always put them to use."
"Haha, you are really good at talking. Once you take out these two things, you will suffer a lot. I can't bear to refuse, so let's do this! I have a book of 'rare prescriptions' here that I have collected and compiled over the years.
You should make a photocopy of the jade slip immediately, and this thing must not be passed on to anyone else!"
Hearing this, Gongsun Yan was overjoyed! He immediately took it, read it with his mind and printed it into his mind, ready to copy it onto the jade slip at any time.
When he quickly handed the silk book back to Gui Danqi, Gui Danqi said in surprise:
"Boy, I didn't expect your mental power to be so strong. It can at least be similar to the cultivation level of the middle stage of Daocheng Realm. I like you more and more. If you hadn't wanted to return to Qingzhou Continent, I would have accepted you as my disciple."
"Grandpa Gui, then you can always accept my Brother Yan as your disciple!" Yi Rui said.
"Haha, I'm just talking. If I really accept this kid as my apprentice, you old guy from the Yi family won't fight me for it! Okay, I won't keep you any longer, and you girl will send them off for me!
"
After saying that, Gui Danqi stood up and left.
Gongsun Yan and his wife hurriedly gave each other gifts. Looking at the old man's back, Gongsun Yan felt very grateful in his heart. He did not expect that a true immortal could be so approachable and enthusiastically helped him. In his heart, he admired Gui Lao's character even more.
Afterwards, Gui Yi took Yi Rui and the two of them to the entrance of the villa. She knew that this sister would soon leave Xuanzhou Continent, and her reluctance was beyond words. The little girl said with slightly red eyes:
"Sister Rui, I hope you will come back to see me soon. I will always think of you."
Yi Rui was also deeply saddened by her and comforted her:
"Well, we will come back often. Immortal cultivators are at home all over the world. As long as you reach the level of cultivation, you can go anywhere in the world. Sister Yi, you should also seize the time to practice!"
After that, the couple left the Guijia Villa in a hurry, leaving the little girl to watch them disappear into the sky before returning with a somewhat lonely expression.
After leaving "Guiyuan", the two of them quickly returned to Huangcheng and went directly to the commercial building of "Hongmeng Chamber of Commerce". This time Gongsun Yan did not disguise himself.
When Men Ying saw Yi Rui's "signature" veil, he immediately came forward and welcomed them into the business building very enthusiastically. After hearing the news, Min Ruoshui also hurriedly went downstairs to greet them and took them directly to the living room of the business building.
.
Then she asked the waitress to bring a tray with twelve black cards and a ring neatly placed on it.
Min Ruoshui took it, placed it on the table next to Gongsun Yan, and said softly:
"Sir, it's all been processed for you. Please take a look at it. The cut scraps have been placed in the ring."
