Seeing that the old man did this again and again, Yang Fan didn't say anything more, and opened the box directly, and what appeared in front of him was a vacuum glass cover, in which a piece of ginseng could be seen lying down.

He was a little dumbfounded, this is what the old man wants to be regarded as a family heirloom? Isn't it just a piece of ginseng! As for the baby?

Yang Shouzheng is such an old and spicy person, how can he not see his grandson's thoughts? He immediately turned straight and said solemnly: "Xiao Fan, don't underestimate it, this is not an ordinary ginseng, but the best old ginseng with an estimated year of more than 3 or 400 years!" I got it by chance decades ago and have always cherished it. It is said to be a good thing that can prolong people's lives! ”

Yang Fan politely refused: "Good things to prolong life, should be given to the elderly, I heard that you were seriously ill last time, why didn't you drink it decoction?" ”

Yang Shouzheng shook his head: "The dietitians in the hospital don't think it's very useful, and some even think it's dried radish." Ordinary ginseng is just that, how can hundreds of years old ginseng be taken and destroyed? They had to take it for analysis and then concluded that it was useless and expired. That's a waste! ”

From the perspective of modern scientific research, the nutritional value of ginseng is only slightly higher, and it is not as miraculous as the efficacy of traditional medicine. From an economic point of view, in the past, the land was vast and there were few people, and it often took a lot of manpower and time to go to the deep mountains and old forests to find ginseng, and even had great risks, and the rate of return was extremely low. Rare is precious, and ginseng is rare because it is rare, so it becomes precious, and when it is precious, it begins to spread magically.

Now there are too many people, wild ginseng has long been dug up, unless there may be some extremely steep or inconspicuous places, most of the sales are artificially planted, and the price will not be so outrageous, but with the identity of precious medicinal materials, it can not be planted anywhere, and it is still more expensive than ordinary medicinal materials. But it is rarely regarded as a life-sustaining drug.

Yang Shouzheng saw that he still didn't pay attention, paused for a moment, thought for a while, and made an analogy: "Let's talk about what you did yesterday!" It is said that an old man can easily injure a few veteran special forces, isn't this scientific? ”

"They have internal strength in their cultivation." Yang Fan said truthfully.

"Can your internal strength be measured with scientific instruments before it is done?"

Yang Fan was not very clear: "Probably not." ”

"That's right, it's the same with drugs!" The old man smiled, "In the past, I couldn't detect the chemical components in Chinese herbal medicine, and even for a long time, there was no concept of chemistry at all, but now I can." However, what cannot be measured now does not mean that it cannot be measured in the future!

Now that the composition of the composition can be studied, it does not mean that the effect of the combination is necessarily a simple addition, and then combined with other drugs, it is more likely to be ever-changing. For example...... It can detect that a person's strength is 100 kilograms, and if the strength of 100 kilograms can knock a person down, can he only knock down one person? If he was faster, more flexible, more experienced, etc., would he have played a bigger role? ”

Yang Shouzheng was full of interest, hoping to be able to convince young people of their ideas.

Yang Fan's heart moved, the internal force could not be measured for the time being, but it did exist, and in the final analysis, it was also a manifestation of energy. The essence of life that can be absorbed from plants is also a kind of energy, is it a similar concept?

He immediately had an immature system concept in his mind: all plants and animals have life essence energy, some strong and some weak. The newly transplanted trees in the city have very low energy, and those old trees that are still alive and vigorous for hundreds of years absorb and gather more energy over time. Ordinary people are very weak, athletes who have undergone special nutritional rationing and systematic training are much stronger, and those who have practiced internal merit are even stronger. The medicine is the plant energy that has a heavy surname, and the elixir of hundreds of years is the medicine that gathers more energy, or absorbs the aura of heaven and earth!

Seeing that his heart was moved, Yang Shou smiled head-on: "Open it and take a look!" This should be what you want, don't think I'm an antique, I've read martial arts novels before. Such an unavoidable thing, even if it can't increase your strength or something, at least it will be of great benefit to your practice! ”

"......" Yang Fan was a little curious, opened the vacuum glass cover, and sure enough, he immediately felt a faint amount of energy, although it was very weak, but it was enough to prove that this and ginseng were indeed a century-old ginseng with aura.

He couldn't help but reach out and grab it, gently grasp and observe, but in fact, he secretly sensed it, and found that this ginseng has really reached hundreds of years, and it contains very strong energy! But it's a pity that when it is dug up, life begins to dissipate, and after drying, although a large part of the energy is still retained, there is already a lot of waste, and there is no life, its energy cannot be retained, and it gradually dissipates over time.

This old ginseng has been dug and dried for decades, and the energy lost adds up to at least half of it!

Yang Fan was looking at ginseng, and Yang Shouzheng was looking at Yang Fan! This old ginseng has been collected by him for many years, but he has seen it completely, and then in order to keep it as a family heirloom, it was vacuum-sealed. But he has personally experienced it, and it is a good thing that makes people feel more energetic after smelling it. This is also the reason why he is seriously ill and is unwilling to take it out casually, so as not to let modern medical scientists waste their scientific research.

Seeing a regretful expression on Yang Fan's face, the old man hurriedly asked, "Do you think there is anything wrong?" ”

Yang Fan shook his head a little helplessly: "No, this is really a very good thing, and it can also be used as an heirloom to save your life, but it's just ...... The efficacy will be inferior from generation to generation! ”

"Why?" Yang Shouzheng was taken aback.

"There are some things in traditional medicine, and the longer you put it, the better. And now we all know the concept of shelf life, even if some things can be kept for a long time without spoiling even if they are dried, the longer the better. Especially a good thing like this that contains aura, the more time passes, the more the aura dissipates. Just like sandalwood, the aroma will still fade over time. Even if some of the time span will be relatively long, but air oxidation, humidity, bacteria, etc., will also have erosion, so ......"

Yang Fan is also very sorry, if the lost ones are completely absorbed by him, he will definitely be able to greatly improve his strength!

Yang Shouzheng frowned: "Then you can't stay!" If you take it once, you will definitely not be able to stand it, and take it slowly separately, it is better to stew soup and grind it into powder and drink it with water? ”

Yang Fanxin said that I can absorb it directly! But this can't be said, grandpa took out the treasure, and he didn't want to enjoy it alone, so he said truthfully: "It's not good, it's a waste." It is best to add other medicinal materials and refine them into pills, so that it can maximize its effect. Although the effect is a little worse, the number is much more. ”

Yang Shouzheng thought for a while, and suddenly said: "It's like the rice wine brewed in the countryside in the past, it is delicious but not much in quantity, and the degree is not high." After adding a little high liquor and water and mixing it and then aging, the quantity and degree have gone up. ”

"It's a pity that refining pills is more troublesome, and it's hard to find those refining pills now...... Equipment. "Yang Fan almost said the Dan Furnace and the Ding Furnace." There are also a large number of medicines, as well as experienced alchemists. ”

Yang Shouzheng nodded understandingly, Yang Fan's master must be very powerful, it can be seen from the fact that he can know so much, but he may not be proficient in everything, and he may not have the methods and talents to refine the pill. "I can offer a candidate for this...... Hehe, my serious illness this time was cured by the divine doctor Chu Zhongtian. He just arranged for his granddaughter to come over and heal me with a prescription. After the effect was effective, he sent a lot of exclusive refining pills for the recuperation of these words......"

As he spoke, he pointed to a jar on the table next to him: "You can take a look, this is it." Of course, for the sake of safety, these pills have been tested by high technology, and they don't think it has a big magical effect, but they are sure that they can't eat the dead before they can rest assured that they can let me eat it. But in fact, the effect is still very good! ”

Yang Fan opened it, took out a jade bottle from it, opened it again and poured out a few pills, and immediately there was an obvious smell of medicine. It doesn't have the legendary fragrance, but it's not surprising that even vitamin pills have a strong medicinal smell. Holding it in the palm of his hand, he seemed to be observing and smelling, but he was still secretly sensing, and it turned out that this elixir also contained a faint energy!

It seems that this alchemy is really not simple, not only the medicinal effect is preserved, but also the aura energy of the medicinal materials can be preserved to be a master, so that it can have a more magical effect.

"What do you think?" Yang Shouzheng asked with a straight face, unconsciously, he was no longer talking to this grandson as an elder, but as a discussion at the same level, which he was not aware of.

Yang Fan also became serious: "I want to visit this Chu Divine Doctor, if he doesn't have a gateway view, maybe he can refine some good medicine!" ”

Yang Shouzheng thought that he was talking about using this centuries-old ginseng as the main medicine to refine some pills, but he didn't know that Yang Fan wanted to refine the pills that only he knew!

In his fused soul, Changfeng, a powerhouse in another world, knew how to refine pills, which was not such a rare thing in their world and era. But Yang Fan, who is in the modern age of the earth, is different, even if he knows the refining methods of these pills, he doesn't know if there are some drugs on the earth, which ones can be replaced by other drugs, as well as the Dan furnace, fire control, etc.

It's like having the soul of a nuclear physicist, even if he knows how to make an atomic bomb, he can't build it empty-handed, but if a country is willing to provide materials and equipment to cooperate, it's different.

"Later, I will ask Rongsheng to help me answer the call of Doctor Chu, and I will explain to him in person, if it is really inconvenient, we will not force it, you can take this ginseng in the best way. Now put him away! Yang Shouzheng pointed to the corner, he even had a black bag ready.

Yang Fan did not refuse, and put away the old ginseng layer by layer, but the glass cover can only be sealed now, and it cannot achieve a vacuum.

"Grandpa suddenly gave me such a big benefit, is there any task to be given to me?"
