The opium poppy is not only the main raw material for the production of opium, but also the source of many sedatives, and the oil produced from the poppy seed is widely used in salads around the world.

The poppy is a real double-edged sword, it is better in the hands of good people, and worse in the hands of bad people, and even in some street stalls in the 21st century, some unscrupulous traders add poppy husks to the soup in order to make huge profits.

At this moment, in the face of these more than ten poppies, Li Chunfeng was a little conflicted in his heart, what is this kind of thing left? Or eradication?

"Li Lang?" Seeing Li Chunfeng looking at these poppies, the big cow on the side couldn't help but say, "What's wrong with you?" ”

"Oh," Li Chunfeng came back to his senses and said with a smile, "I have seen this flower before, and I never imagined that I would be able to see it again in my lifetime." ”

"Yes," Li Daniu said proudly, "I can guarantee that there is no second home for this poppy flower in Chang'an." ”

"How so?"

Li Daniu said: "This poppy flower is extremely delicate and difficult to raise, and most people would rather raise other flowers than raise it." ”

"Delicate?"

"When Master was alive, I was told that poppies need to be sown between spring and summer, and they need special fertilizers."

"What fertilizer?"

"Corpses." Li Daniu said, "Bury the carcasses of some animals in the ground, bury them with soil, and then sow poppy seeds on them, and the nutrients produced by the carcasses decay can ensure that poppies grow from summer to late autumn." ”

Speaking of this, Li Daniu frowned for a while: "So in the summer, the backyard of the Taoist temple is filled with a rotten smell. ”

Speaking of this, Li Chunfeng can be regarded as understanding, such a method of raising flowers with corpses, most people will not try.

Only those who have an urgent need for poppies will grow such a thing as poppies. Moreover, under such harsh planting conditions, it is impractical for ordinary people to want to grow poppies on a large scale.

Therefore, poppy flowers are very rare in Datang, and thinking of this, Li Chunfeng couldn't help but breathe a sigh of relief.

Human beings are sometimes like this, when they see something very harmful, they will naturally magnify the harm infinitely, thus covering up those beneficial sides.

Li Chunfeng turned around, took the "pill" from Da Niu's hand again, and asked, "Da Niu, do you remember the process of your master refining the elixir?" ”

Da Niu scratched his head: "I only remember to take poppy seed shells into the Dan, it seems that I also used clay pots and hot pots, but ...... At that time, I was still young, very playful, and it had been a long time, so I couldn't remember it clearly. ”

"Poppy husks?" Li Chunfeng was stunned for a moment, "You mean, your master used poppy husks to refine the Dan?" ”

"Well, I must be right by mistake," said the bull, "I remember that I peeled the shell every time." ”

"Well, I see."

Li Chunfeng finally understood why this "elixir" that smelled so bad could be sold for 30 yuan, because this elixir was refined from poppy husks, and the morphine contained in poppy husks was addictive.

Li Daniu was overjoyed and said, "Li Lang, do you know how this elixir is refined?" ”

"Uh...... A little brow-raising," Li Chunfeng said, "but I'm not too sure." ”

Looking at Li Daniu, Li Chunfeng said: "You said, after your master uses this elixir, he has to peek into the way of heaven?" ”

"Yes," Li Daniu said, "Master has a happy face every time he uses this medicine, saying that he has experienced the floating feeling of feather ascension. ”

Hearing Li Daniu say this, Li Chunfeng was even more sure that his master must have taken this so-called "pill" and was addicted, so he had that fluctuating feeling.

"Speaking of which, I also want to try, what kind of feeling is that......" When he said this, Li Daniu's eyes lit up a little as he looked at the wooden box in Li Chunfeng's hand.

Li Chunfeng frowned, and said, "Eh, Da Niu, this elixir, it's better to put it here with me first, and then return it to you after I study and understand the refining method, how about it?" ”

Li Daniu was a little reluctant, and said, "Okay, but you have finished researching, you must return it to me, this is the last piece left by the master." ”

Looking at Li Daniu's reluctant appearance, Li Chunfeng couldn't help but smile and asked, "Aren't you afraid that I will lie to you?" ”

"Why are you lying to me?" Li Daniu asked honestly.

Li Chunfeng was stunned for a moment, and then joked with a smile: "Back then, Qin Shi Huang sent someone to find two elixirs, take one for himself, and let me take the other one, I won't take it, I'll take you!" ”

"What? What do you say? Da Niu was full of question marks by Li Chunfeng's words, "You have an elixir?" ”

"Uh...... Forget just now," Li Chunfeng was a little incoherent just now, "that's just an illusion......"

Da Niu was speechless for a while: "......"

Putting the wooden box away, Li Chunfeng sighed: "Come on, it's time to do business." ”

As he spoke, Li Chunfeng walked out of the backyard of the Taoist temple, and came directly to the place where the "pots and pans" were placed, looking at those large and small, various materials.

Li Chunfeng pondered a little and selected two utensils, one large and one small.

"Big Niu, go get me a bucket of water."

"Oh, good."

Li Chunfeng put the palm-sized small vessel in the middle of the large wooden basin of the basin, then thought for a while, and poured half of the saltpeter into the wooden basin evenly.

"Li Lang, the water you want is here."

The big cow came from outside the Taoist temple with a wooden barrel, and Li Chunfeng was stunned: "Where did you get this water?" ”

"In the stream, the water in this stream is very sweet," you said with a smile, "When Master makes tea, he often asks me to take water from the stream." ”

"That's right."

Li Chunfeng muttered, took the bucket from Da Niu's hand, and said, "Da Niu, I'll pour this water into the basin later, you listen to my order, and immediately use the big basin next to it to help me buckle it up." ”

"Oh, good."

After giving the order, Li Chunfeng first added the water from the wooden bucket to the small vessel in the middle, and after a slight pause, began to pour the water into the wooden basin.

The water entered the wooden basin, and the saltpeter reacted quickly, Li Chunfeng quickly poured a small half basin of water, and then said: "Big cow, cover it!" ”

"Good!"

The big cow, which had been preparing for a long time, quickly covered the wooden basin with a utensil on the side, only to hear the sound of "zizi" coming from inside.

Li Chunfeng stretched out his hand and stroked the wooden basin, and a few minutes later, a chill came from the wooden basin.

Li Chunfeng was overjoyed in his heart, and said secretly: "It's done." ”

Because he was afraid that too much water would not condense into ice, Li Chunfeng only poured a small amount of water into the small vessel in the middle, so that it was easier to condense into ice.

About ten minutes later, Li Chunfeng felt that the time was almost up, and raised his hand to open the wooden basin.

Suddenly, a cold air rushed to his face, and a white mist appeared above the wooden basin, Li Chunfeng looked confidently into the small vessel in the middle, but found that the water inside was not all condensed into ice! Only a thin layer of ice visible to the naked eye floats on the water.

This result greatly surprised Li Chunfeng.
