Yu Shan said with a smile: "We have obtained the formulas of two pills, and we can also synthesize Chinese patent medicines, so the difficulty of alchemy should not be too big, so that our strength can be quickly improved." ”

"It seems that in the future, these people who come to the door really can't refuse all of them." At this time, Yu Shui opened his mouth.

Yu Shan said: "It's not always so lucky, this kind of lucky person with Su Hui is not common." ”

Sent Yu Shui and Yu Hai to cultivate, Yu Shan returned to the house, it seems that he will always keep in touch with Lin Yujie in the future, there is no foundation, and now Yu Shan can only get a large number of medicinal materials through Lin Yujie.

"Yi Jin Dan is very useful for practitioners in the Ming Jin period, and it is even more useful for some special foreign kung fu, since it is the easiest to refine, it is better to take Yi Jin Dan as a breakthrough first, as long as there is a main pill in your hand, you will not worry about the medicinal materials in the future." Yu Shan sighed helplessly.

There are a lot of pill formulas in his hands, such as Sanyang Dan, Liuyang Dan, Bailing Dan, Erjia Dan, and Yangyan Dan, which can be used and will be snatched up, but Yu Shan does not have qualified medicinal materials, so the refined ones are all defective, which is not competitive.

In the following days, Yu Shan contacted Lin Yujie from time to time, urging him to send medicinal materials, and finally a week later, Yu Shan gathered enough medicinal materials for three furnaces of Yijin Dan, and also gathered enough medicinal materials for washing the myelin pill.

"Except for the Tianshan Snow Lotus and the Intermittent Grass, these medicines are not too expensive at all, even if they are elixirs, they are all contaminated with a trace of aura, and they are not enough to make people wash their hair and cut off the marrow and be reborn, right?"

Looking at the medicinal materials in his hand, Yu Shan was a little puzzled, with the aura in these medicinal materials, could it really bring such a big change to the body?

Tianshan Snow Lotus is not to say, intermittent grass is a good medicine for bones, even the little-known jack pull, but also has the effect of relaxing tendons and activating the nerves, strengthening the muscles and bones, reducing inflammation and relieving pain.

With so many muscles and bones in one place, it should have the effect of legend.

"Okay, just refine a furnace of pills and try it."

After making a decision, Yu Shan began to clean up the Dragon and Tiger Ding and prepare to refine the Yijin Pill.

Follow the steps to melt the medicine, constantly fuse the medicine, and finally put the snow lotus into the pill, as long as you know the method, now Yu Shan alchemy is very proficient.

The elixir is indeed different from ordinary medicines, just to melt the medicine, you can't rely on the Dragon Tiger Ding alone, but you need Yu Shan to keep inputting the spiritual energy to urge the Dragon Tiger Ding to heat up continuously.

Fortunately, Yu Shan's skills have increased a lot recently, otherwise he would really not be able to fuse drugs smoothly.

Wait until all the medicine melts into liquid, Yu Shan relaxes a little, at this time, Cheng Dan is needed, Cheng Dan can only rely on the dragon and tiger ding, or rely on Yu Shan's luck, if the formula is not right, then everything is in vain.

As Yu Shan kept inputting aura, at this time, the liquid medicine in the dragon and tiger tripod began to become a pill, and the dragon and tiger hugged the pill, which was definitely not a waste of fame, if he simply relied on Yu Shan, he could only use his heart and soul to gather the liquid medicine while inputting the aura, so that the liquid medicine could solidify and form the elixir.

Now, Yu Shan only needs to control the aura he outputs to assist the Dragon Tiger Ding to succeed.

"There are too many medicines, and nine whirlpools have been formed at once." Perceiving the situation inside the Dragon and Tiger Ding, Yu Shan could only smile bitterly.

This is the first time that Yu Shan has formed so many pills, nine whirlpools at a time, and at the same time competing for the medicinal liquid inside the Dragon and Tiger Ding, if all of them become pills, then nine Yijin pills will be formed at one time.

And with such a furnace of medicinal materials, the figure at the level of an alchemy master is only ten pills, so Yu Shan would never have thought that he would be able to become nine pills at a time.

Alchemy alchemy, the most important thing is Cheng Dan, what is Dan, in fact, there are several kinds, one is ancient refers to cinnabar, a red mineral containing mercury, and the second is an adjective, describing the color as red as cinnabar, for example: red-crowned crane, Danfeng, Danhong.

Then there are the ancient Taoist cinnabar and other refining medicines, such as: alchemy, Jindan, granular or powdered Chinese medicine made according to the prescription, according to the degree of difficulty is divided into, powder, ointment, pill, pill.

Powder is some medicinal materials ground and put together, and now the ordinary important boiling is powder.

Needless to say, the plaster is further boiled out according to the medicinal materials to form the plaster.

The pill is based on the plaster, and it is further made into a finished medicine.

Dan, as the name suggests, condenses into Dan and refines it into a pill with a certain stable structure, which can be stored for a long time and is not easy to lose its efficacy.

Therefore, when the elixir is formed, it is actually a process in which atoms and molecules fuse and pull each other to form a stable state.

In this process, either because the combination of medicinal materials is unreasonable, or the heat is not enough, or the external force acts, anyway, anything may affect Cheng Dan, and these need experience to make up.

Therefore, in order to avoid trouble and reduce the consumption of medicinal materials, in the past, Yushan alchemy was to minimize medicinal materials.

In the initial test stage, it is not clear how much medicinal materials are put in, so generally Yushan is a furnace of pills and only leaves the amount of medicine to refine two pills, so that it can be very easy to become a pill, and as for the medicinal materials of the other one, it will be used as a supplement to become the guarantee of another pill.

And today, he refined the Yijin Pill for the first time, and he couldn't grasp the amount of medicine, so he directly threw in a furnace of ten pills, Yu Shan didn't expect that there were actually nine pills about to be formed at a time.

Although he knew that it was unlikely that nine pills would be formed at once, Yu Shan was still very excited.

He carefully maintained the whirlpools inside the Dragon Tiger Ding, allowing them to form pills as much as possible.

In this process, Yu Shan constantly adjusts the internal situation, for example, if one vortex absorbs too much medicinal power, then it needs to be reduced and assigned to another vortex.

For example, if a whirlpool shows some signs of collapse, it should be stirred again to allow the herbs attracted by the whirlpool to mix.

Some whirlpools lack power, and they are about to stop rotating, so that if the medicinal materials are not enough, Yu Shan will give up, but now that the medicinal materials are enough, it is impossible for Yu Shan to give up, so he outputs aura to increase the power of the vortex, so that it can continue to absorb the surrounding medicinal materials and condense into a pill.

Nine vortices slowly attract the surrounding herbs to form nine particles, and as the rotation speed increases, the particles become larger and larger.

Seeing that there were fewer and fewer medicinal liquids inside the Dragon Tiger Ding, and none of the nine pills showed signs of failure, Yu Shan became excited.

At this time, it is necessary to look at the completeness of the formula, if the medicinal materials are enough, then the nine pills are likely to succeed, if the medicinal materials in this furnace are insufficient, then the alchemy evenly distributed by the liquid medicine this time is likely to fail.

At this time, although Yu Shan thought of the consequences, there was no room for regret.

"A furnace of medicinal materials is only a few hundred thousand yuan, and I can bear it even if I fail once."

Yu Shan was ruthless, urged the aura again, and prepared to Ning Dan.

In a series of bumping sounds, Yu Shan's palms hit the dragon and tiger tripod that was burned golden again and again.

"Knock knock!" From time to time, there was a sound like a bell ringing in the valley.

"Boom!" After the last loud bang, the valley became calm.

"Whether it will be successful or not, it will be done in one fell swoop." Yu Shan directly smoked the firewood below and began to cool down the Dragon Tiger Ding.

The Dragon Tiger Ding is an ancient pressure cooker, even if the flame below is extracted at this time, the Dragon Tiger Ding will not be able to lower the temperature for a while, so Yu Shan can only wait.

"I don't know if I can design a modern alchemy furnace with a stirrer and automatic adjustment of internal pressure."

Yu Shan looked at the dragon and tiger ding, in fact, alchemy relies on temperature and pressure, and then it is to adjust the ratio of internal medicinal power, and others require experience, but raising the temperature and enhancing the pressure cannot destroy the Dan furnace, this needs to rely on the quality of the Dan furnace.

The ancient metallurgical technology is not too much, so it is difficult to cast a qualified alchemy furnace, and the dragon and tiger tripod are obviously an outlier.

Feeling that the elixir should have been formed, Yu Shan opened the air valve and directly released the pressure.

In the midst of a sneer, a strong medicinal fragrance spread.

"What elixir scent? It's so intense. At this moment, Qian Xiaohao's voice sounded from outside.

"Yu Shan, this guy is secretly refining good things again, hurry up and go over and grab one." Pang Tong's grinning voice sounded.

"Why are you here?" Yu Shan didn't rush to open the Dragon and Tiger Ding, but looked at Qian Xiaohao and Pang Tong, these two guys have not shown their faces once since they left on the first day of the Lunar New Year.

"Haha, I'm back, Xiaoshan, do you want me?" At this moment, the fifth knife walked in from the outside, carrying a large bag.

"Haha, accident, right? The two of us went to the capital once and it was a bonus. Qian Xiaohao said, turned around and pulled in two large backpacks.

It's a typical hiking backpack, half the size of a person, and it's bulging with stuff.

"It's all medicinal herbs?" Yu Shan asked.

Qian Xiaohao said with a smile: "Almost all of them are medicinal materials of Bailing Pill, and there are some of them, which are enough for you to refine a furnace of Sanyang Pill." ”

"Sanyang Dan? Ginseng must be at least 500 years old, deer antler velvet and tiger bones must be produced from spirit animals, and at least the heat needs to be more than 60 years, are you sure? Yu Shan looked at the three guys, they would really surprise him.

"I have a lot of relationships, otherwise, I really can't buy more than sixty years of deer antler velvet, and tiger bones are even rarer, I heard that this tiger bone is the bone of a tiger essence, and it is still fresh, I don't know if those people are fooling us, can there be tigers in modern society?" Qian Xiaohao said with a grin.

The fifth knife said in a rough voice: "No one in the capital dares to lie to me, I have never been in contact with this industry before, but our fifth family, no one dares to fool." ”

"Okay, knowing that your family is powerful, quickly take it out and let Yu Shan take a look at it to see if it is a real tiger elf bone." Pang Tong said. (To be continued.) )
