"The ...... of your world The rice yield is very high! I wonder if I can take some back with me when I leave?"

"I'm afraid not!" Cheng Yun directly denied his words, and then frowned and recalled his almost forgotten biological knowledge and experience in the countryside when he was a child, and said, "Our current rice is called hybrid rice, and you must master its technology to produce its seeds, otherwise, even if you bring its seeds back and plant them, only the yield will be high in the first year, and the yield will be very unstable in the second year." ”

"Huh?" General Li was stunned and his eyes widened, "that's so. ”

"But you don't have to worry. Cheng Yun said, "Hybrid rice is far from being the most productive crop in our world, and the reason why we eat it every day is just because we are used to it." If you're desperate to solve your food problem, root crops are the way to go. ”

"Tubers and root crops?"

"Yes, for example, the sweet potatoes with the highest yield, and then sweet potatoes, sugar beets and potatoes, etc., usually the yield per mu can reach thousands of kilograms, which is very terrible! And they are often simple to grow, have a high survival rate, and are rich in starch, which is a good choice for coping with famines. Cheng Yun said, pausing, "I think what you should be worried about is how you bring these seeds back, and how long it will take for such a little seed you bring back to be planted on a large scale." ”

"It's really a problem. General Li frowned deeply and looked at Cheng Yun again, "Dare to ask the stationmaster, if I borrow the Void Order Arrow of the Heroine to leave, how many things can I bring?"

"I'll get you a tricycle, or a van, at most. Cheng Yun was also uncertain, "It should be able to pass." ”

"I'm tired of the stationmaster!"

"You're welcome, these are trifles. ”

"But I still need weapons!" General Li quickly added, but he looked embarrassed when he finished speaking, "I also know that in your country, even swords are controlled products...... But the weapons of your world can make an ordinary soldier have the combat power to fight against aliens, and if I can master the manufacturing method of your world's weapons, all the creatures in our world will really be saved!"

"What weapons do you need?" Cheng Yun frowned deeply, "Modern weapons are very complex, manufacturing methods are difficult to obtain, and it is also very difficult for you to master. But some of the older weapons are still relatively simple. It's just that I don't know whether the weapons of our world can take effect in your world, and whether the basic materials of our world are the same as your world, it's a matter of rules......"

"Bombs, cannons, big guns, ......" General Li did not say about planes and tanks, nor about those weapons that he couldn't understand, but only said the simplest, "I have to give it a try." ”

"Well, the bomb is easy to say, nitrocellulose, nitroglycerin and the like are not very difficult, and the power is not bad. Cheng Yun pondered, "It's more difficult to use the cannon, but it seems that your world also has some kind of means to solve the problem of materials and processes." As for the big guns...... I can only tell you the basic principles of firearms, look up the drawings of old-fashioned firearms on the Internet, and see if you can learn it. But by big guns, you mean ......"

"It has to be bigger than a normal gun, otherwise it won't kill enough aliens. General Lee said.

"Oh!" Cheng Yun nodded.

"If you can get your hands on these weapons and show them to me...... That couldn't be better. General Li himself was embarrassed to say this, but he had to say it.

"You think so highly of me that I can't even get you that tiny pistol. Cheng Yun shook his head, paused, and his eyes lit up again, "But I remember that you seem to have said it before, you said that you really want to see the battlefield of our world?"

"Yes!" General Li nodded, very frankly, "precisely because I want to see the weapons of your world. ”

"That's going to be easy. Cheng Yun nodded, silently measuring in his heart, "I can discuss with Lady Yin a little bit, borrow her treasure Ling Arrow and use it, theoretically I can use it to send you to a place where war is going on in our world." Those places are full of weapons, and with your skills, no matter how you use to get some guns, it won't be a problem. But I'm a little unsure about the actual operation, I can only try the magic master's scroll once, just once. ”

General Li was a little embarrassed when he heard this: "At that time, I will have to bother the stationmaster again." ”

"It's a tired woman. ”

"Okay, when I finish the other things first, and when I get to this point, I'll let me do the things I discussed with the heroine!"

"That's fine!"

Just as he said this, two thin figures riding small yellow cars came over not far away. One of them still had a can of Sprite in his hand and rode with one hand, drinking as he rode.

It was Yin Nuxia and Yu Dian who went out to buy clothes.

Both of them had bags for clothes in their car pockets, and there was also a bag hanging on the left side of the handlebars of Yin Nuxia, which seemed to have gained a lot.

Soon, they had driven to the door of the hotel, locked the little yellow car on the side of the road, got out of the car and walked towards the hotel with their bags.

"Hello Boss Cheng. The little girl whispered.

"Eh, what are you two talking about here?" asked Lady Yin, sucking Sprite's habit into a gurgling sound.

"Let's talk about his business. Cheng Yun smiled and said, "Buying clothes went well, right?"

"It's ok. Yin Nuxia was a little distressed, she obviously didn't feel cold, but the stationmaster had to let her buy new clothes, and she didn't need to keep out the cold, so she always felt that she had bought two sets of new clothes for nothing, hundreds of dollars!

"By the way, the stationmaster, we also bought a kind of cake, what is it......" Yin Nuxia was stunned, turned her head to look at Yu Dian, "What kind of cake?"

Yu Dian replied in a low voice: "Moon cakes." ”

"Yes, yes, yes, moon cakes! I said that I was going to have a moon cake festival recently, and I wanted to eat moon cakes!" Yin Nuxia said.

General Li asked beside him, "What moon cake?"

"This is a traditional festival in our country, called the Mid-Autumn Festival, which is traditionally for the whole family to reunite and enjoy the moon together. Because there is a full moon in the Mid-Autumn Festival, everyone eats a round cake called a moon cake, which means reunion. Cheng Yun said.

Yin Nuxia was stunned to hear it, and then nodded hurriedly: "Yes! That's it! That's what the man who sold moon cakes said." ”

"It's quite expensive to buy mooncakes outside, so it's better to buy them online. Cheng Yun said, buttoning his head again, "I was thinking about buying moon cakes on Taobao this morning, but I forgot about it!"

After speaking, Cheng Yun pushed open the glass door and walked into the front desk, yawned and said to Cheng Yan: "The Mid-Autumn Festival will be in a few days, should we buy some mooncakes to eat on the Internet?" There are still a lot of people in the hotel, buy more, and then send one to each guest." ”

"What are you telling me for?" Cheng Yan raised his head and looked at him inexplicably, "You just buy it! …… I'm going to eat lotus paste egg yolk flavor!"

Tang Qingying at the front desk heard it, and hurriedly said: "I want to eat crayfish-flavored, Su's!

"Perverted!" Cheng Yan whispered.

Cheng Yun shrugged his shoulders and said to Cheng Yan: "I'll leave it to you, anyway, when we renovated the bed room before, we also opened intimate payment!"

Cheng Yan: "......"

"I'm going to eat bean paste, pumpkin, and custard. Cheng Yun continued.

Cheng Yan: "......"
