In fact, for a moment, Liu Chengfeng wanted to give up alchemy.

He silently calculated in his heart that 500 catties of herbs could be exchanged for 3 to 4 bottles of Huanglong Dan, in exchange for about half a century-old ginseng, and he would not lose money on this transaction.

But in the case of alchemy, how many bottles of elixir can be refined from one ginseng?

For a novice, his confidence is really not very strong. Liu Chengfeng carefully considered that if the chance of becoming a pill was one in ten, then one ginseng could only refine 8 pills.

It's only 8 pieces! There are not even two bottles of pills, so there is no way to guarantee the cost at all, so why bother to do alchemy? But after thinking about it, if you don't go to alchemy, you will not be able to guarantee the cost.

During the Qi refining period, you can also use ordinary herbs to deal with it. What about the foundation building period, the Jindan period, and even the Yuan infant period?

The pill suitable for taking during the foundation building period, the cheapest one is also 22 spirit stones per bottle, and if you exchange it for ordinary herbs, it can barely support it.

But when it comes to the Jindan period? Can you still use ordinary herbs? With tons and dozens of tons of herbs at every turn, it is really worrying to think about the resources on the earth alone!

From this point of view, learning alchemy to improve the rate of becoming a pill is a good way to save costs. Therefore, if you want to plan for the long term, you have to learn alchemy honestly.

After figuring out the joints, Liu Chengfeng felt a lot more relaxed.

Since he had promised Bai Lao to invest in technology, the first thing Liu Chengfeng did after earning the spirit stone was to go to the mall to buy the formula. Shengjisan and hemostatic san are both secular bruising and injury medicines, and the price is not expensive, and the total is only 10 spirit stones.

However, it is a meditation pill, which is a commonly used auxiliary medicine for immortal cultivators, and even Jindan Avenue is still useful, so the price is a cut higher, and it takes 13 spirit stones to buy it.

With the three formulas in hand, the 35 spirit stones instantly shrank to 12, plus the Dan furnace that had not yet been purchased, Liu Chengfeng seemed to have become a poor egg again.

With a slightly bitter smile, Liu Chengfeng was a little helpless. I have to admit that this spirit stone is very unflowered, and it is gone after only a few clicks.

Fortunately, the formula has arrived, and when the formula produces benefits, more spirit stones will come in.

Since Liu Chengfeng didn't understand medical science and was not too familiar with medicinal materials, after the formula was in hand, he just picked out a formula and hastily looked at it a few times before putting it away.

As for the cost price of the formula, can it be mass-produced? It can only be left for tomorrow, so that Bai Ruobing can sum it up.

There was nothing to say all night, and in the early morning of the next day, Liu Chengfeng woke up from his steady state. After a few days of absorption, the aura in that spirit stone had been completely absorbed by him.

However, it is a pity that Liu Chengfeng's realm has not broken through, and he is still hovering at the peak of the first layer of Qi training.

Although he did not break through to the second layer, the aura in his body was extremely full, and he fought with him in the middle of the second layer of qi training.

At half past nine, Bai Ruobing came to the pharmacy with a little pinch. The old rule, first handed over a delicious breakfast, and then put on a white coat, then picked up the medical book and sat side by side with Liu Chengfeng behind the counter.

"I thought you were going to make the pharmacy smoky, why? Didn't you transport the medicinal materials yesterday?" She heard her grandfather say yesterday that hundreds of catties of medicinal herbs would be delivered in the evening.

While eating breakfast, Liu Chengfeng replied, "The medicinal herbs were delivered last night, but I transported them away......

Hearing that the medicinal materials had been transported away again, Bai Ruobing turned his head in surprise and looked at Liu Chengfeng with a look of surprise. This guy is sick, right? Since he has to transport it away, why should he have his family transport it to the pharmacy? It is better to have someone deliver it to his destination.

Of course, Liu Chengfeng understood Bai Ruobing's thoughts, but he had already thought of how to respond last night, so he opened his mouth to explain: "My refining medicine is different from your refining medicine, so the medicinal materials required are also different. What if I don't check it myself, what if I don't pass it?"

"Is that so?" Bai Ruobing asked suspiciously, and waited until Liu Chengfeng nodded heavily before she was relieved.

After eating breakfast, Liu Chengfeng took out the formula, and then handed it to Bai Ruobing and said, "This is the formula of three medicines, you can help take a look, what is the cost price?"

Being able to get the formula so quickly made Bai Ruobing look quite surprised. However, she didn't ask much, but was attracted by the formulas of the three medicines, so she immediately grabbed her hand and watched it carefully.

Liu Chengfeng sat next to him, and also carefully observed Bai Ruobing's facial expressions, trying to analyze from her facial expressions, can these drugs also shine in real society?

Soon, Bai Ruobing's brows twisted into a pimple, which made Liu Chengfeng's heart tighten, so he couldn't help but ask, "What's wrong? Can't it be produced? Or is the cost price too expensive?"

Bai Ruobing didn't answer, but thought about it contemplatively, and replied after a long time: "That's not it, I just can't believe it, it's obviously a very ordinary medicinal herb, but when combined, it has such a miraculous effect, are you sure this recipe is true?"

Hearing Bai Ruobing's question, Liu Chengfeng patted his chest and assured that it really couldn't be true. The mall must lose the boutique, how can there be a fake?

"The cost price of hemostatic powder is not high, and it can also be mass-produced, but it is a bit troublesome to build muscles, because some of these medicinal materials need to be specially brewed, but they must be mass-produced after improvement, but they are just ......" Bai Ruobing commented one by one, but in the end, he actually hesitated, which made Liu Chengfeng's let go of his heart lift again.

So I couldn't help but ask, "Just what?"

At this time, Bai Ruobing pushed the formula of the Meditation Pill in front of Liu Chengfeng, and then asked, "What's going on? Dan Furnace? Samadhi True Fire? What about you cultivating immortals? Also, please tell me that the Divine Cultivation Fruit is a Divine Horse Dongdong, what kind of tree can produce this kind of fruit?"

Bai Ruobing was a little angry, she had just had a good impression of Liu Chengfeng, but she didn't expect Liu Chengfeng to fool herself, which was really hateful.

Well, Liu Chengfeng is a little embarrassed. When he got the recipe last night, he hadn't double-checked it, so he wasn't very clear about what it needed. However, it is obvious that the Meditation Pill is an elixir taken by immortal cultivators, and it is difficult to produce it in the world, or it is impossible to produce it at all.

Fortunately, he reacted in time, seeing that Bai Ruobing was a little angry, he immediately explained with a smile: "Sister, don't be angry first, let me explain that it's not too late to be angry again! What about people who practice qigong, in ancient times, they were called qi practitioners, and it is not surprising that ancient qi practitioners could refine pills and medicines, so the meditation pill may be an ancient pill prescription, as for the nourishing god fruit? It may be a different title, right? The ancient nourishing god fruit may also be called white fruit, black fruit or something ......in modern times."

Hearing Liu Chengfeng's explanation, Bai Ruobing's anger had already disappeared by half. In fact, she doesn't need a real explanation, she just wants an attitude. As the teacher said, it doesn't matter if your grades are good or bad, but you must have the right attitude.

Undoubtedly, Liu Chengfeng is a good student with a good attitude, Bai Ruobing covered his mouth and snickered twice after listening to Liu Chengfeng's explanation, and then said angrily: "You can talk ...... it."

Whew, it's finally fooled......
