The greenhouse is almost made, and Feng Xiaoyue has been living in the backyard to observe. Many days have passed, and some clues have been discovered.

Murong Yu's domain was to the north, and the people relied on the mountains to eat the mountains, and the general cold air was blocked by the high mountains, so it stagnated above the domain. Last time in the suburbs of the city, most of Uncle Wang's seeds were harvested at the foot of the mountain, not in the vast plains, so by mistake, most of the seeds that Feng Xiaoyue got in his hands could only survive in temperate or subtropical climates.

How can temperature-loving plants grow in this subarctic monsoon climate? It can only be said that the dense mountains and forests and the good thermal insulation effect can allow Wang Bo to receive these rare seeds, but this brings a problem to Feng Xiaoyue.

"Xiaoyun." Feng Xiaoyue thought about it and made up her mind. Once you have these seeds, you can't waste them, and even if a dead horse becomes a live horse doctor, there will always be a glimmer of life.

"Miss, you call me." Xiaoyun was watering the flowers outside, and suddenly heard Feng Xiaoyue calling her, and almost thought she was hallucinating.

"Xiaoyun, you go and replace all the seed water trays that have not yet germinated with warm water to soak, don't be too hot, the seeds will not be able to stand it." Feng Xiaoyue stood up with the corner of the table, and Xiaoyun hurriedly went up to help her.

"As for those that have already sprouted, divide them first, call a few people, and I'll tell you what to do later."

Xiaoyun helped Feng Xiaoyue to sit outside the room wrapped in a straw curtain, which was full of seed water trays, and several girls were separating the seeds.

The girls work together, one pours out the water, the other pours the warm water, and the other takes the poured water out, and the action is fast.

When they were all separated and the water was changed, the girls mopped the ground clean, and Xiaoyun helped Feng Xiaoyue in.

The seedlings are immature, so naturally they cannot be planted directly in the ground. The water tray used for seed germination is wide, flat, and made of porcelain, although it is bulky, but there is no need to worry about it being rotted by the wet soil. The water tray is filled with soil and may be used as a substitute for the seeding tray.

"You, take the remaining empty water trays, one by one, to the backyard and bring some soil back, as long as the soil surface is a little lower than the edge of the water tray." Feng Xiaoyue looked at the number of water trays and the number of germinated seeds, and after careful calculation, she asked these maids to run twice, maybe it would be about the same.

"Yes." The little girls hadn't done any of these things, and they felt strange for a while, so they could run fast with the water tray.

"Xiaoyun." Feng Xiaoyue pulled her, "You ask someone to move a few cases over, and they are spread out in this room." ”

"Miss, isn't there a table here?" Xiaoyun was afraid that she would be left alone and refused to go.

"The table is too high, put it on the ground, this floor made of wooden planks will be soaked in a short time, take a few tables, and it will not affect the small buds to take root, and it will not let no one enter this room in the future."

Feng Xiaoyue didn't blame her, and slowly told her the reason, Xiaoyun didn't understand what she heard, so she could only praise: "Miss, you know so much." ”

When the case came, the maids also brought the water tray and put it on the table.

"Insert a bamboo skewer into the soil surface, open it down, put the small buds into the pit that has opened, and then gently cover the soil with a bamboo skewer. Remember to leave some distance between each small bud, otherwise it will be difficult to take it out in the future. ”

The maids sat cross-legged on the floor and planted the small buds according to Feng Xiaoyue's words, and the sunlight shone in from the south, just projecting on these small buds planted in the soil.

Murong Lin came to see Feng Xiaoyue today, but found that she was not in the room. As soon as I came out, I saw a few little girls holding water trays, and ran to the backyard with a plate of soil. The heart said, it must be Feng Xiaoyue who came up with something new.

On a whim, Murong Lin followed the direction of the little girls and followed the past to see what was new.

Seeing that she asked someone to move in the case, plant young shoots, and that theory, Murong Lin snickered in his heart, only thinking that Feng Xiaoyue was a half-truth, and suddenly wanted to be an old farmer.

It was warm in the greenhouse, and Feng Xiaoyue was sitting there, and she couldn't help but fan away a little heat. was busy, Feng Xiaoyue looked at the door, and Murong Lin was standing next to the door frame.

Murong Lin saw that his whereabouts were discovered, and he also walked in generously. As soon as he entered the house, he felt a burst of heat.

"Your house is warm enough." Murong Lin approached Feng Xiaoyue.

Feng Xiaoyue had to look up at him, "It's not enough, the seeds are very afraid of the cold." You feel hot just because you're used to the cold outside. ”

Saying that, Feng Xiaoyue paused, "But the ironsmith has news?" ”

Murong Lin couldn't help but smile when he met her hopeful gaze, and spread out the drawings he had brought with him on the table.

"Exactly. But he doesn't go out, and you can't walk, so I'll just mark it all on this piece of paper, and I'll tell him about it. ”

"Can you remember?" Feng Xiaoyue glanced at the drawings and turned her head to look at Murong Lin.

Finding Murong Lin's displeasure, Feng Xiaoyue couldn't help but hide her face with her sleeves, so as not to be found out laughing at him.

"I have asked someone to measure this room, it is eleven zhang long and ten zhang wide. To get heat to every corner of the room, the longest iron pipe should be at least 14 zhang. ”

Murong Lin looked at her as she spoke, calculating the result, and sighed in her heart that she was so fast in her mental arithmetic. Write down everything Feng Xiaoyue said to avoid mistakes.

"As for the other lengths, I think the ironsmith can also calculate them according to the drawings." Feng Xiaoyue's eyes were indifferent, and Murong Lin knew that she was suspicious, so he responded for the ironsmith. After all, if this little thing can't be done, he is not worthy of building weapons for the palace.

"How do you lay it?" Murong Lin asked.

Feng Xiaoyue raised her head and thought for a while, "The floor of this room is about three feet away from the land, and I need to lay another floor two feet from the ground." Lay the iron pipe between these two floors, then the thickness of the iron pipe should not exceed one foot, preferably about half a foot. ”

Murong Lin raised his eyebrows, this was indeed a test for the ironsmith.

"What are you doing with this pipe?"

Feng Xiaoyue glanced at him and pointed to her right back.

"Here, when the iron pipes are laid, a water stove is placed. Since there are planks on both sides of the iron pipe, it is not good to burn charcoal. ”

"The location of the doorway has sunlight coming in, and the iron pipe does not have to stick to the first floor under the floor, taking advantage of the height difference between the two ends,"

"Pour boiling hot water." Murong Lin Mauser had an epiphany and interjected.

"Exactly." Feng Xiaoyue nodded, "And boiling water in this room can also raise the temperature of the upper part of the room together." ”

Hearing this, Murong Lin couldn't help but smile lightly and grabbed Feng Xiaoyue's hand, Feng Xiaoyue wanted to take it back, but she couldn't break free.

Murong Lin said in a deep voice: "The idea is very good, I will cherish your hard work." ”

Feng Xiaoyue's heart moved, and she forgot about the struggle.
