In the following time, Lu Zheng did not immediately follow Xi Beiyue to the business, but asked the other party to take him to the most famous medicine pavilions and medicine stores in Dongcheng District to continue to understand the market in the trading of medicinal materials.

Most of these medicine pavilions and medicine stores are concentrated in the same block, and the shops are all carved and jade, which is splendid, reflecting the absolute wealth and magnificence. Around them, there are small and medium-sized medicine shops, and the stars hold the moon to form a cluster effect.

On the streets here, you can see powerful warriors everywhere, rich children who are gorgeously dressed and either rich or expensive, as well as medicine farmers and merchants who come and go.

According to Xi Beiyue, the competition in the medicinal materials industry is extremely fierce, especially in the supply of raw materials, and there are dozens or hundreds of large and small businesses, chambers of commerce, and those big medicine pavilions themselves are engaged in a large number of purchases of medicinal materials.

Among them, the Great Medicine Pavilion and the most powerful large chambers of commerce generally have channels for planting medicinal fields and purchasing large quantities, while small and medium-sized businesses such as Litong Firm, in addition to their own private channels, also have a large part of them to purchase medicinal materials from retail investors such as medicine farmers and hunters.

Moreover, some of these merchants will supply medicinal materials to those big medicine pavilions and big chambers of commerce, but the profits are relatively low, while the other will set up their own caravans and sell them to the cities around Dasai in Western Xinjiang to buy and sell them, so as to obtain a higher profit difference.

Under the leadership of Xi Beiyue, Lu Zheng visited a number of well-known medicine pavilions and medicine stores, in these biwa and zhu eaves, in the extraordinary shop, in addition to the common medicinal materials, all kinds of cultivation pills are dazzling, including the hundred refining ointment, true martial qi and blood pills seen in the black market before, and what ginseng, tai sui, snow lotus, yellow essence, He Shou Wu and other precious medicinal materials are not uncommon, eye-opening.

And whether it is a finished pill or the main material of precious medicinal materials, the selling price is very expensive, even the cheapest qi and blood tonifying decoction, with a pair of prices must be counted in silver teeth;

Of course, that's not his purpose. With Xi Beiyue being such a know-it-all, his understanding of these medicine pavilion medicine stores and the sales of medicinal materials has improved rapidly, and a complete plan has emerged in his heart.

More than an hour later, after visiting all the large medicine stores, Lu Zheng, who was completely numerous, no longer wandered around, and immediately returned to Litong Firm's own medicine store with Xi Beiyue, ready to choose the medicinal materials he needed.

Li Tong Pharmacy is also located in this area, but it is located in a relatively remote street, the shop is not very large, and there are few customers in and out.

After entering the medicine store, Xi Beiyue immediately called the pharmacist from home, and took Lu Zheng directly through the back hall to the well-defended warehouse.

In the warehouse, the smell of all kinds of medicines was mixed and strong, and under Xi Beiyue's orders, an old pharmacist over fifty years old took out more than a dozen palm-sized small medicine boxes according to the requirements and opened them one by one.

Mountain ginseng and ginseng with slender roots, Polygonum multiflorum with thick roots, and Polygonatum polygonatum with cylindrical rhizomes...... There are more than a dozen pill boxes, all of which are relatively valuable main material drugs, but the quality of the year is relatively average.

Of course, the quality of the vintage is generally Lu Zheng's own request, and he immediately touched it lightly to get the year information of these medicinal materials.

[Codonopsis (5 years)], [Ginseng (7 years)], [Ginseng (9 years)], [Huangjing (6 years)......

More than ten pieces of information flashed one after another, and what was surprising was that among the more than ten medicinal herbs, there happened to be one mountain ginseng that had just reached the limit of the ordinary grade of nine years, which perfectly met his needs!

In this regard, Lu Zheng did not hesitate and directly selected the main material of this big medicine.

Since the development of medicine refining and pharmaceutical, only the finished pills refined by special methods can increase the efficacy of these big drugs to a greater extent, although Xi Beiyue did not know what the use of Lu Zhengguang to buy this main material, he did not ask much, and only charged the cost price of ten gold leaves.

Lu Zheng, who got what he wanted, was satisfied, and after thanking the other party again, he found a reason to return to the house alone.

At this moment, the house was quiet, Ning Kun, Song Yuan, Xu Hu and others, who were led out to see the world by Lianghu, had not yet returned, he went straight back to his house, immediately locked the door of the house, and then took out the medicine box in his arms.

Inside the medicine box, a dried mountain ginseng about two fingers thick was lying inside, exuding a vague medicinal fragrance.

Mountain ginseng, great tonic vitality, shengjin quenches thirst, generates essence and aphrodisiac, generates blood and replenishes blood, it is an absolute tonic for people who practice martial arts, among all the main materials of great medicine, it is also the most demanded and sought-after one, Lu Zheng did not see any hesitation and directly tapped his fingers, and silently recited in his heart:

"Strengthen!"

Airplanes!

In an instant, the surface of the sun-dried mountain ginseng suddenly bloomed with a strange brilliance, illuminating his face.

In the process of blooming brilliance, he clearly saw that the mountain ginseng shrouded in divine brilliance quickly began to expand and grow, and every time the brilliance flickered, its size soared by a few points, as if the lens had accelerated its growth and development at a speed of ten million times!

Then, after only a few breaths, the mountain ginseng in his hand, which was originally only two fingers thick, grew in size by two or three times, and became as thick as a child's arm. At the same time, the shriveled shape of the original irregular shape has faintly grown roots similar to limbs, and it looks like a villain who is close to forming!

A strong fragrance of herbs and trees came to his nose, and the information of the mountain ginseng in Lu Zheng's sight had become:

【Mountain ginseng (90 servings)】

Quality: Boutique (blue)

Description: Nearly 100 years of mountain ginseng, nourishing qi and blood, greatly replenishing the vitality of the human body, strong medicinal power.

[Remaining Enhancement Essence]: 5 points

"Became ......"

The palm-sized medicine box could no longer fit the ginseng that had become two or three times larger, Lu Zheng held this extraordinary mountain ginseng, and his eyes were eager:

"Then the next thing is to find a way to get it out......"

Through the previous stepping point and Xi Beiyue, an industry insider, he already knew the year of the main material of the big medicine, which played a vital role in the potency and grade of the pill. Those precious and superb elixirs can only be refined with the main materials of a hundred years of medicine.

However, the resources of heaven and earth are limited, and the treasures of heaven and earth in the deep mountains and old forests also need a long time to grow, which is simply not enough to withstand the consumption of thousands of martial artists' cultivation.

Therefore, these big medicine pavilions in the Western Xinjiang Great Fortress who have mastered the refining techniques of cultivating secret medicines may not care about the medicinal materials of ordinary years, but there is a great demand for the main materials of the big medicines of high years, and if he takes out this ninety-year-old mountain ginseng, even if there is only one, it will inevitably be rushed to buy!

What's more, Lu Zheng also knocked on Xi Beiyue's side, these Great Medicine Pavilion Medicine Stores have a strong capital background, even rare coins like Tianfu Treasure Money, and they also have a lot of reserves to accumulate.

If he does it properly, he may be able to directly save the link of finding and exchanging the Heavenly Rune Treasure Money, killing two birds with one stone!
