Closing the shelves that appeared in the void, Yang Yi found that its closure was quite simple, and when he pushed the three rows of shelves together, it would automatically close and disappear. I tried to open it again, and sure enough, it was raw and ripe once, and it was easy to open. The point is that it seems that this ring will absorb some kind of force in its own body and use it to drive this space.

With the task given by Alda in mind, Yang Yi sat down to study the book "On the Synthesis of Potions".

After opening the book and only turning a few pages, Yang Yi felt that it might be called so-and-so Daquan to be true. The content given in it is really specific and detailed, not only using a similar method to give a general outline, but also according to classification, parts, articles, chapters, sections, subsections, and subtle to the five organs.

After browsing the bibliography, Yang Yi flipped through it casually and saw that the number of words written under the page was 625 pages. My heart moved, and for some reason, I continued to turn back, and the standard at the bottom of the page became one hundred and thirty-one. Suddenly, Yang Yi knew that something was wrong, and continued to turn it back vigorously, and sure enough, the number of pages became two thousand three hundred and thirty-eight.

A little common sense knows what it will look like when the thickness of the paper exceeds 2,000 pages? And this book made of leather, which is obviously thicker than paper, looks like two fingers thick, but it is more than 2,000 pages!

Yang Yi suddenly felt a little numb in his scalp, which obviously broke his understanding of things. Immediately, he didn't dare to flip back, for fear that something would go wrong, so he honestly followed the catalog to find the location of the primary recovery potion.

As a primary potion, it wasn't hard to find, and Yang Yi found it on page one hundred and seventy-four.

At first glance, I was at a loss again. Ancient English is already difficult to understand, if it weren't for the perennial estrus roommate in Xitan to learn ancient Western poetry as one of the necessary means to pick up girls, Yang Yi would have learned this after eating it. But what is surprising is that Yang Yi's talent for learning ancient English is completely shocking, and in just one month, Yang Yi's proficiency in ancient English is almost as proficient as his native language, as if he was born to speak this language. This surprised the roommate, and also called the MMs who learned ancient British poetry together to explode. It's a pity that Yang Yi was born with incomprehensible amorous feelings, and he would rather hold the standard ancient poems and gnaw them, and he didn't notice the illegal closeness of the MMs.

Now Yang Yi looked at the potion synthesis method, and he recognized the words on it, but he couldn't understand what it meant when they were combined.

The description of the primary recovery potion is roughly condensed like this: as an entry-level recovery potion, its effect is weaker than that of the primary healing potion, but due to the different refining methods and the difference in materials, this elixir has the effect of driving away a small amount of dark force while having a healing effect. Then there are the tools to be used, the medicine pestle, the No. 2 flask, the No. 4 dropper, and the stirring ...... No, no, no, no, a lot, Yang Yi is dizzy to see. Then there are a lot of materials, so detailed that even the spare medicine is marked.

Yang Yi was dizzy for a while, and suddenly understood a question: Why did he understand its principle so much? Mo Ming came to this inexplicable place, saw inexplicable people, heard inexplicable words, got inexplicable things, and then did inexplicable things after the last time, which of these is something that people can understand? Just like the Newton-Leibniz law in calculus, you can use it, and there is no need to make trouble to deduce and verify it.

Thinking so in my heart, I suddenly felt that my mind was clear for a while, and I just had to follow the steps and draw the scoop according to the gourd.

In a different direction, things are much simpler. But this simplicity is also relative, for example, the primary recovery medicine will use the Banzrod beard grass, and God knows what this Dongdong is. So I went to look for the herb encyclopedia again, and found it with great difficulty. It is originally a parasitic grass that lives on tree branches, and it is only born on the branches of a tree called camphor, and usually hangs down with a long leaf that is very similar to a beard, and the gentle texture will make it move with the wind, hence the name of the beard grass.

Yang Yi is 100% sure that he has never seen this thing before. Now they are dried and spread out on the table, and they look like beards that have actually lost their nutrients and become dull after leaving the human body.

First read the formula, then read the "Encyclopedia of Herbal Medicine", found the right herbs, and laid them out one by one, Yang Yi began to have a headache again.

The recipe says that there are several roots of Bunzrod beard grass, two sawtooth silver leaf grasses, one tranquilizing flower, and one grass root of knotweed, ten drops of water containing holy power, mash the herbs to extract the juice, and then use the light system power to stimulate it after dropping into the holy water.

The concept is very mushy...... How many roots, how many are they? One plant, or two, how big is this one? They are not cast in a mold, of course, they are big and small, which is very headache. It's like cooking an inaccurate measure word for an apprentice who is at a loss when faced with a little salt, a little oil, an appropriate amount of soy sauce, and heating it to the right temperature. It's a bit too vague.

Yang Yi himself is a sophomore, and he is used to making the amount of substances accurate to grams, or even milligrams, and the volume quantifiers are refined to milliliters, and the quantifiers are microliters. It is important to know that if a chemical test tests a little more or less of a certain substance, it is very likely that the result will be an explosion. In medicine, a little more or less of a certain drug is synthesized to determine whether the drug is made to kill or save people.

The book in front of me is full of words like how many plants, how many leaves or how many petals, and it is not at all that the exact amount of the Dao is known, is this a murder potion or a life-saving potion? Yang Yi suddenly wanted to give up.

Looking at the table of herbs and worrying, after thinking about it, I decided to give it a try, hoping not to poison people......

Mash all the medicines mentioned in the recipe, strain the juice with a cotton cloth, and get a small beaker of slimy dark green and yellow juice. This is followed by ten drops of water with holy power. Sweat!...... What is water with holy power? When I turned my head and looked around, I saw a large open bottle soaked in a silver chain with a cross hanging from it, and I couldn't help but feel like my heart moved, as if it was all played out on TV. Immediately he picked up the dropper, took some of the water, and dripped it into a small beaker.

One drop, two drops, three drops...... When Yang Yi thought that his idea was ridiculous, the small beaker suddenly bubbled, giving people the feeling that it was a huge chemical reaction that occurred after a strong acid and alkali were mixed together. Yang Yi was taken aback, couldn't help but take two steps back, and looked at the small beaker on the table in disbelief. No way...... There's really movement, and it's not small. Is there really a holy water in this world? I thought it was an apocryphal thing born in response to movies and television...... I didn't expect it to be!

I ask for a recommendation and collect it
