Mr. Changpo didn't go crazy, and Xu Rui didn't.

The reason why he was so excited was only because this so-called weed had a name in another world, called the flower of Vladimir or the flower of the male.

This plant is not native to Earth, but a magical species discovered on a terrestrial planet by the first space explorer, astronaut Vladimir Ontario, after the Big Bang.

In terms of plant characteristics alone, the little medicine boy is not wrong, Vladimir's flower grows quickly, is cold and drought resistant, has an escaping smell and insect repellent effect, and is not good for anything else, it is indeed a standard weed.

But its magic lies in the fact that its rhizome contains a substance, which can only be obtained through pure chemical synthesis before, that is, the famous "sildenafil citrate", commonly known as "Viagra"!

Because only a special extraction method is needed, "sildenafil citrate" can be easily obtained from the flower of Vladimir, and then purified by traditional pharmaceutical means to obtain low-cost medicines, resulting in the almost bankruptcy of Pfizer, which has monopolized the "Viagra" market for more than 100 years, which shows the great impact caused.

Although Xu Rui has not systematically studied pharmaceuticals, he happens to extract "sildenafil citrate" from the flower of Vladimir, and the method is similar to the purification of a certain high-explosive drug.

So he also took a look at it when he was learning about explosives manufacturing, but he didn't expect it to come in handy now.

In a patriarchal society with low medical conditions and legal second wives (three wives and four concubines), there will inevitably be many people with lofty ideals who are "old and ambitious", and "Viagra" is the light of hope for them to re-embark on the peak of life.

And Xu Rui, who holds "viagra", is not equivalent to sitting on a mountain of gold?

It's really sleepy and encountering a pillow, going out and picking up a treasure.

Xu Rui seems to have seen a lot of silver beckoning to him, where can he still hold back the beastly nature that is about to move?

He didn't look at the other medicines, and he immediately asked the little medicine boy to find him an empty room, and brought a lot of messy and strange things, and then hid in it with a bundle of freshly baked "weeds".

When he closed the door, except for the thief smile on his face, his expression and demeanor were exactly the same as Mr. Changpo's.

Outside the door, the little medicine boy and Xu Ange looked at this scene dumbfounded, and glanced at each other blankly.

"Gotcha, another crazy ......"

After a while, the little medicine boy sighed, shook his head, and left by himself.

An Ge also smiled bitterly and went home.

Whether he can make a fortune is a later story, but today Xu Rui jumped home is true, the young master can do his own thing, but An Ge didn't dare to be so arrogant, so he had to return to Liu's mansion tremblingly.

Mrs. Liu is kind and kind, and occasionally does not return home at night for problem teenagers, and she naturally does not say anything more if she talks nonsense.

It's just that the complaining gaze, and the long sighs from time to time, are like sharp arrows piercing people's hearts, making An Ge panic and guilty, always feeling that he has failed people's hearts, and the crime is extremely evil, it is better to beat him comfortably.

Early the next morning, An Ge couldn't stand the strong sense of guilt, and sneaked out of Liu's Mansion again without even eating breakfast, and ran to Yaowangzhuang in one go.

What he didn't expect was that the Medical Holy Hall, which was deserted yesterday, had only been separated by a day, and there was a long queue.

Could it be that the young master's whereabouts have been exposed?

An Ge's face changed, and he hurriedly squeezed into the crowd, only to find that these people were all carpenters with axes and saws in their hands and full of sawdust.

"Listen to it, the person who got the drawings will start work now, young master, I will see things in the afternoon!"

An Ge finally squeezed to the front, and saw Xu Rui sitting on the recliner talking quietly, and the little medicine boy was holding a thick stack of drawings and giving one to each of the carpenters in line.

The carpenters who received the drawings only had to glance at them, and suddenly their mouths opened, their eyes widened, and their expressions exaggerated squatted in the corner of the wall to ponder carefully.

An Ge was curious, and when he leaned over to take a look, he saw that the carpenters were holding engineering drawings with all kinds of parts drawn on them, not only with detailed explanations for each key point, but also simple and vivid physical sketches.

Xu Rui drew these sketches according to the standards of industrial design, although due to the lack of tools, it was already very rudimentary by his standards.

But in these years, carpentry work is often done with a size, and carpenters have never seen such exquisite engineering drawings? No wonder every carpenter feels like he's seen a ghost.

made such a big battle, naturally it was not that Xu Rui was full and had nothing to do, he really had hardships and couldn't say it.

Although "sildenafil citrate" can be easily obtained from the flower of Vladimir using a special extraction method, this is by the standards of another world.

At least 34 processes, such as "crushing", "grinding", "fermentation", "distillation", "reaction", "concentration", and "purification", are even more difficult to put in a world where there is hardly any industrial base.

It's like a tempting fruit hanging from a high branch, which you can see clearly, but you can't eat it, let alone how uncomfortable it is.

Of course, there are still ways to solve the problem, but it is certainly impossible to manufacture precision machinery temporarily, so in desperation, Xu Rui had to adopt a compromise solution, that is, to build a special small pharmaceutical workshop.

Although the cost of small workshop production is high, the efficiency is low, the quality standards are not uniform, and the safety and health are difficult to guarantee, it is not a long-term solution from any point of view, but it can at least allow Xu Rui to produce decent products.

The conditions are limited, and it can only be completed and improved first, and it seems that industrialization is imperative......

Xu Rui thought faintly, and sighed helplessly.

"Young master, old man, I will do it for you for nothing this time, if you don't charge money, will it succeed?"

Just as he was thinking about it, an old carpenter in his fifties suddenly approached Xu Rui quietly, whispered a word, and then laughed flatteringly, revealing a mouthful of big yellow teeth.

Is there such a good thing in the world? Nothing to offer, either treachery or theft......

Xu Rui opened his half-closed eyes, slowly got up from the Taishi chair, looked at the old carpenter carefully for a moment, and asked, "If you don't want money, then what do you want?" ”

The old carpenter smiled, pointed to the engineering drawings in his hand, and said a little shyly: "The old man wants to learn how to draw from the young master......

Xu Rui was slightly stunned, took a good look at the old carpenter, and asked, "Why?" ”

The old carpenter said: "I won't tell you, I have been a carpenter all my life, but I have never seen such a picture, and today is an eye-opener."

As the saying goes, a mountain is a mountain, but the old man thinks that the mountain in the eyes of the young master is the real mountain, so I also want to see what the mountain looks like in the eyes of the young master. ”

Xu Rui was silent for a moment, and then asked: "If you learn my craft, you are my person, are you willing?" ”

The old carpenter was silent for a few moments, as if he was hesitating, but finally nodded.

Xu Rui thought for a while, took out another stack of drawings from his pocket and handed it to him.

"In three days, if you can make this thing and still meet my requirements, I will teach you."

"Really?"

The old carpenter took the stack of drawings in surprise, looked down and swept it, and his face suddenly changed.

If the drawing I got before was a work of art, it was as rough as papyrus compared to the current stack.

The new drawings are densely packed with marks, every detail is described in detail, and the size, material, and weight of all parts have strict requirements, accurate to the millimeter level, and it is extremely difficult to complete by hand.

"This ......"

The old carpenter has done carpentry work all his life, so he didn't know what it was, so he just glanced at it and looked at Xu Rui.

Xu Rui patted him on the shoulder with a smile and said: "If you can make this thing, the young master will keep you, and you will immediately become the most powerful carpenter in the entire Daxing City, count the money and count the cramps when you get it, haha, come on, I'm optimistic about you!" ”
