In the underpass, under the leadership of Gu's sister-in-law, the whole road seemed to be very long, but after only a short walk, it came to the end of the road.

When Xia Wuhe walked out of the intersection, he felt a sudden light in front of him, and a vast underground world full of strange flowers and plants appeared in front of him.

"What are these flowers?"

"No one knows why, this place existed earlier than Wuchuan City."

After this conversation, it was obvious that Sister-in-law Gu also didn't know why so many flowers and plants could grow in a place where there was no sun shining under Wuchuan City, which also made Xia Wuhe figure out one thing, why there were some special medicinal materials that were difficult to collect in Old Man Liu's pharmacy.

The underground valley in front of him gave people a kind of pure natural polishing, Xia Wuhe didn't expect that in the underground passage of Wuchuan City, there was such a world, and the whole place was very large, at least hundreds of meters of space.

Looking closely, the open space in the center is a large blue brick square, in which there are many familiar neighbors, who have turned into small vendors, and set up small stalls around the square.

In front of the stall, from time to time, one or two people would crowd in front of them, look at them for a moment or two, or ask a few words in a low voice, but I didn't see a few transactions on the spot.

Sister-in-law Gu was helpless and explained: "The materials are tight, Wuchuan has been consumed in the past few years, and it is good that everyone can trade things in their hands, as for the medicinal materials in the valley, in the past, only Old Man Liu picked them alone, and others did not know much about medical skills." ”

That's the truth...

Thinking like this, the people gradually approached the square with the stalls.

The neighbors saw Xia Wuhe appear, although they were a little surprised that Sister-in-law Gu brought this kid over, but they didn't react too much, after all, Xia Wuhe himself was born in Wuchuan, and he was not an outsider in the strict sense.

The wide square is sparsely arranged out of a zigzag path. And those who choose to trade items walk in twos and threes in the middle of the open space with stalls on both sides, coming and going, quite a kind of fireworks.

Although this is an underground area, the square is brightly lit, and most of the stalls have been placed in front of the uniform lanterns, which are antique and give people a bright feeling, and the lamps are placed in the valley of a special ore, once lit, the surrounding will become incandescent bright.

The light emitted is much brighter than that of ordinary oil lamps, and not only does it illuminate the stalls as if it were daytime, but even the periphery of the nearby underground roads is clearly visible, which makes people marvel.

Just when Sister-in-law Gu and Xia Wuhe were observing, there were many more people in the square than just now, not only did they add some stalls, but the number of people shopping at the stalls also increased dramatically.

Xia Wuhe collected some medicinal materials, the whole process was very smooth, many vendors selling medicinal materials were dead horses as live horse doctors, after the death of Old Man Liu, there was no doctor in Wuchuan City, basically these medicinal materials were sold cheaply.

As for the medicinal materials in Old Man Liu's own shop, they were taken to the square by several village elders to deal with them.

At the beginning, when they saw Xia Wuhe collecting medicinal materials, everyone thought that he was just like everyone else, preparing some earthwork medicines to drink by himself, but Xia Wuhe didn't seem to have much money on him, and the acquisition was not smooth at first, until half an hour later, he got the medicinal materials he needed from a person, but it seemed that he took it for nothing?

"Old Wu, why can Xia Wuhe take these for nothing?"

The vendor named Lao Wu smiled: "He didn't take it for nothing, he promised to use these potions to refine a bottle of Jinchuang Medicine." ”

Referring to this matter, a few vendors who didn't sell it to Xia Wuhe just now shook their heads: "Old Wu, are you crazy, the raw materials of the core of Jinchuang Medicine are missing, even if he has learned medical skills from Old Man Liu, it is useless." ”

The ingredients of Jinchuang medicine are very simple, mainly musk, rosin, lard, yellow wax, camphor, borneol for boiling, filtering off the trickle to be cold, and then stirring well into the end of the medicine, porcelain storage, where the knife and axe are damaged, the fall is broken, and the application is applied to immediately relieve pain and stop bleeding, not to mention pus.

But the problem is that in Wuchuan City, the most lacking is lard, and in addition, the best Jinchuang medicine also needs a keel, and the so-called keel is the shell of the oracle bone inscription in Xia Wuhe's previous life.

Old man Liu's pharmacy used to ask for a few bottles of Jinchuang Medicine, and the sale was expensive, and he was completely a black-hearted profiteer, but now this kid is much easier to deal with from the transaction just now.

Lard and keel, without these two things, it is difficult to refine the best gold medicine. So a few people were a little skeptical about Xia Wu when they heard it, and why did they say that they could refine the Golden Creation Medicine!?

"So Lao Wu, you are quite bold and dare to give him so many medicinal materials."

"Haha, Sister-in-law Gu assured me that this kid had stolen from Old Man Liu's shop before, and basically he would know how to do it, as for how to solve the keel and lard problem, how could people say it, I just need to ensure the authenticity of the medicine, and I should gamble."

When it comes to Old Man Liu, many people have palpitations, although the government is looking for traces of Old Man Liu everywhere, but the people in Wuchuan who are familiar with the injuries in his body know very well that Old Man Liu is likely to be unable to suppress the injuries in his body, and he went mad and self-immolated to dissipate.

Many neighbors on the side are also whispering: "The fifteenth day of next month is coming soon, if you can really prepare more medicine, it will be excellent." ”

"It's a pity that Xia Wuhe, who made his sister too good."

In order to facilitate the refining of medicine, someone in the square deliberately gave Xia Wuhe a firing grotto, at this time, Xia Wuhe had just lit the furnace, and Gu's sister-in-law, who walked in, put down a large number of collected medicinal materials and was a little uncertain: "Wuhe, can you really refine gold and create medicine?" ”

Xia Wuhe under the firelight showed a confident and sunny smile: "Don't worry, leave it to me Little Doctor Immortal Xia Wuhe." ”

"Is this old man Liu dying and starting to teach you so many things with kindness?"

"Sister-in-law Gu, have you confirmed that Liu Lao is no longer alive?"

In this way, many people know that Old Man Liu will die soon, which makes Xia Wuhe even more vigilant about the truth behind the Six Miao Xuanyin that Old Man Liu recited before his death.

"Probably..."

Seeing that Sister-in-law Gu was reluctant to answer, Xia Wuhe was not reluctant: "Sister-in-law Gu, please help me take care of it outside, it will be fine soon." ”

The real Jinchuang medicine, Xia Wuhe has no way to replace lard and keel, but he has dozens of bottles of various injuries that rely on the task in his hand, so Xia Wuhe, who uses his brain quickly, grinds it into powder, mixes yellow wax, camphor, and borneol and then boils it to make a new medicine.

The pills in a bottle of wound medicine, combined with these medicinal materials, can refine twenty bottles of Xia Wuhe's version of the Golden Creation Medicine, in fact, the effect of this medicine is similar to that of the Golden Creation Medicine, which can deal with ordinary external injuries.

Smoke was billowing from the grotto, and many neighbors, including Lao Wu, were staring wide-eyed, waiting for Sister-in-law Gu and Xia Wuhe to come up with some elixir.

"I gave him so many medicinal materials, if there is no lard and keel, the effect of the substitute Jinchuang medicine is very limited, and the speed of hemostasis is even slower, if there is only this effect, it is better to treat it yourself."

Lao Wu smiled: "It's okay, try it"
