Lin Yi said: "I am looking for a material, if I can be lucky enough to find this material, I can not use charcoal to heat, this material can absorb light and heat, if this material is used as the roof of the greenhouse, it can absorb and preserve the light and heat emitted by the sun during the day, so that the temperature inside the greenhouse can be much warmer than the outside, so that although the cold wind is fierce outside, but the inside can be like spring all year round." ”

"Is this material a transparent, very smooth thing?" Ji Qianmo asked.

Lin Yi nodded and said: "It is transparent, a bit like glass, but although glass can permeate heat, it dissipates heat quickly because it is permeable, so at night, the greenhouse will suddenly cool down and become very cold, so that the crops planted in the greenhouse will be frozen to death." ”

Ji Qianmo nodded and said: "I once saw a magic trick in Xiyou City in the west, he had a glass bottle, the bottle was very peculiar, after being burned with a fire, the outside of the bottle was still cold, but the wine in the bottle could become warm, and it was not cold for a long time, according to the daughter-in-law, this kind of glass bottle should be the kind of material you want, right?" ”

Lin Yi nodded and said in surprise: "That should be it, Mo Lang, where is Xiyou City?" Is it far from here? ”

Ji Qianmo reached out and touched her little head, and said with a smile: "This is the Rongdi Shadow Capital in the Far North, Xiyou City is in the west of Tianchi Country, adjacent to Xixia Kingdom, and it is naturally 108,000 miles away from here." ”

Lin Yi was slightly disappointed, and said: "It's so far away, then after we leave Rong Di, we will look for it over there, but before you go to find it, you must not leak this secret, this is a trade secret." ”

"You little money fan!" Ji Qianmo couldn't help but tap the tip of her nose and said, "Your husband and I, are you so talkative?" “

Lin Yi grabbed his arm, rubbed his little face on his clothes, and said with a smile: "I know, I know." ”

Ji Qianmo smiled: "However, since you said that this material is so important, how about I send someone over there to inquire first?" ”

Lin Yi nodded and said, "Okay." ”

Ji Qianmo bent down and lowered his head, reached out and picked up a sweet potato vine, looked at it carefully, and said: "This sweet potato vine grows really well, I have seen sweet potatoes in the south, the climate is mild, the sun is abundant, and the sweet potato vines grow very luxuriantly, I didn't expect that my daughter-in-law could grow such lush sweet potatoes in the ice and snow in the far north." “

Listening to Ji Qianmo praising herself, Lin Yi felt beautiful in her heart, and she smiled: "These are vines, I have been planting them for a long time, and the sweet potato vines outside are only afraid that they are still very small, and I will not be able to see the effect after a while." ”

"Seeing that your vine grows so well, the sweet potatoes planted outside should also grow well." Ji Qianmo said with a smile.

Lin Yi said: "Then let's take a look, tomorrow, we will leave here to go to the palace, and it may take a few days to come back." ”

"You're going to the palace? That's too dangerous, how about you just stay here and wait for everything to settle down outside, and then go out? ”

Because of the change in Xiahou Jun's identity, Ji Qianmo knew that there would be great changes in the palace of Rong Di Kingdom recently, and at this time, Lin Yi would undoubtedly put himself in danger when he went to the palace again.
