"Of course, this potato is not so difficult to feed, cut it into pieces, plant it in the soil, and it will grow into new potatoes in the end, so General Niu doesn't have to worry about the potato being eaten." Zhang Nan said with a smile.

"I see, it's the first time the old man has seen something that has been cut open and can continue to grow." Niu Jinda is also amazed.

"That's right, but you must be careful when eating, you must not eat sprouted potatoes." Zhang Nan suddenly remembered that if he accidentally ate the sprouted potatoes, he might die.

Why is that? If you don't eat the sprouted potatoes, won't it be wasted? Li Er frowned and said.

"This sprouted potato contains a toxin, which is harmful to the human body, and it can cause itchy throat, nausea and vomiting, and death if you eat it, so you must remember that sprouted potatoes can't be eaten." Zhang Nan said.

"Isn't this sprouted potato a waste?" When Li Er heard Zhang Nan say that the sprouted potatoes could not be eaten, he immediately hesitated, whether he should satisfy himself in advance first, or keep these three potatoes as seeds.

"If it won't be wasted, cut the sprouted potatoes into pieces, make sure that each potato piece has two or three sprouts on it, and you can grow into new potatoes if you plant them, and you won't waste them at all." Zhang Nan said.

"In that case, Liu Bing, then take some potatoes and send them to the imperial dining room, and tell those people to do it well, I will eat this today." Li Erdao.

"The old slave obeys." After speaking, Liu Bing gave the little eunuch standing on the side a look, and the little eunuch immediately stepped forward and began to pick potatoes, and when the selection was completed, the little eunuch took this basket of potatoes to the imperial dining room.

"Your Majesty, you see that these flowers are beautiful, and the concubine wants to move a few plants to the concubine." Standing beside Li Er, Empress Eldest Sun saw some wilting flowers not far away, and said with a smile.

"Okay, since you like it, take it back and take care of it, I think this thing looks pretty too." Li Erdao.

"Jinda, what's the name of this flower, it looks really good, can you bring these plants back?" Li Er turned his head and said to Niu Jinda, who was standing beside him.

"Back to the emperor, this flower minister was also found on an island, and the ministers couldn't understand what the natives on the island said, but the ministers exchanged a lot of things with them with our Tang Dynasty pottery, and this flower was also given to the ministers by them. The name seems to be quite awkward, what is the name of Diyajia, and the minister doesn't know what it means. Niu Jinda scratched his head and said.

"Dejeja, what's that name?" Li Er also shook his head, obviously this name did not conform to Comrade Li Er's aesthetics.

"By the way, the emperor, the group of natives on the island seem to use this as a medicinal herb, if the emperor wants to figure out the pharmacology of this flower, he might as well let Daochang Sun take a look, maybe he can figure it out." Niu Jinda said.

"Yes, I see."

"But on that island, not only did I see the natives using this flower as a medicinal herb, but also people sucking it." Niu Jinda suddenly remembered something, so he spoke.

As soon as he heard the word "sucking", Zhang Nan's ears pricked up, how did this sound a little wrong.

"Smoking? Can flowers be smoked too? Li Er was puzzled.

"No, no, no, I watched the group of natives pick the fruit of this thing, and then scrape it open with a knife to drain the juice inside. After the juice is dry, it can be sucked. But this thing is medicine, and the minister thinks that it is a medicine that is poisonous, so when the group of natives asked the minister to try it, the minister didn't try it, but this guy tried it. After Niu Jinda finished speaking, he pointed to a lieutenant general who was following him.

"Oh? Have you tried? What does it feel like to smoke this stuff? Li Er asked with interest.

After the vice general Li Er was named, he looked a little excited, and the whole person was trembling, and then he hurriedly arched his hand and said: "If you go back to the emperor, after the minister tried this thing, he felt a little dizzy at first, but after a while, he was like falling into the clouds, and he was very happy." ”

After Li Er heard this, he showed a look of eagerness to try, and after Zhang Nan heard it, he hurriedly stood up and asked, "Then do you still want to suck this thing now?" ”

The deputy general obviously knew Zhang Nan too, and when he heard Zhang Nan's question, the deputy general also arched his hand to Zhang Nan, and then replied: "Back to Lord Zhang's words, it's a little, but it's okay." ”

After Zhang Nan heard this, he nodded with a palpitating look, and then said to Li Er: "Your Majesty, this thing can be kept and seen, and it can also be used as medicine, but it must not be sucked. ”

"Oh? Is it so serious? Li Er obviously didn't believe that a small flower could have such a big impact.

"The truth may be more serious than that." Zhang Nan said with a solemn face.

"We have this thing anywhere, but the minister didn't think about it for a while, but when he heard the word "sucking", the minister knew what it was. Zhang Nan said.

"So what is this?" Li Er said curiously.

"If you go back to the emperor, this kind of flower, the minister will call it the poppy, the flower is very beautiful, but its fruit, if specially made, can be turned into a drug." Zhang Nan said.

"Drugs?!"

As soon as he heard Zhang Nan say the word drugs, the deputy general who had taken it was also startled, and then hurriedly said: "Lord Zhang, is it possible that you are taking drugs?" I didn't feel anything uncomfortable in my body. ”

"That's because you suck less, naturally nothing, but if you smoke it for a long time, it won't take more than a month, and I dare to guarantee that you can't do without this thing." Zhang Nan sneered.

"If this thing is used to suck, when sucking, there will be a sense of pleasure and excitement like falling into the clouds, and people are very excited, but once you become addicted to this thing, when you are addicted to drugs, you will definitely not be able to keep up your spirits, if you can't suck it all the time, the whole person will sobble and go crazy. And if you smoke it for a long time, you will destroy people's bodies and wills, and you are now a lieutenant general, and you may be able to kill the enemy on the battlefield, but if it takes a long time, you may not even be able to lift a knife. Zhang Nan looked at the deputy general and said word by word.

"Is it that serious?" Li Er obviously didn't expect that this small flower could be so harmful.

"Naturally, there is, so this thing must be strictly controlled, medicinal, it's okay, but once you treat it as a treat, it's over." Zhang Nan did not have a grin-haha on his face at this time, but said with a serious face.
