Jia Huan looked around the lushness in the house, especially the three-layer shelf structure, which greatly improved the efficiency of space utilization. Jia Huan nodded with satisfaction. △↗

The use of large windows and transparent glass, coupled with heating of the kang, makes the greenhouse almost perfect.

However, using a greenhouse to grow vegetables in winter was not the first to Jia Huan. In fact, there were clear records about greenhouses in the Han Dynasty nearly two thousand years ago: "From the Han Dynasty's Daguanyuan, green onions, leeks, and vegetables were planted in winter, and the house was shrouded, warming the fire day and night, all the vegetables were born with warm air."

However, this kind of greenhouse can only be used by a very small number of people, such as princes and nobles.

As far as Jia Huan knows, there is also such a greenhouse in Rongguo Mansion, which is managed by a dedicated person, and is exclusively for the enjoyment of Jia Mu, Jia She and Jia Zheng and his wife.

Lin Daiyu and Jia Baoyu can naturally enjoy it with Jia Mu, and Wang Xifeng and his wife can also make up one. As for the others, it is probably good to have a barely see a green leaf. This is already a master's level treatment. Anyway, when I was in the Jia Mansion, there was very little green in the bowls of Jia Huan and Aunt Zhao...

Moreover, their greenhouses are extremely inefficient because they do not have transparent glass windows and can only use oil paper to paste windows. The light transmittance of oil paper is very poor.

How can green plants grow well without abundant sunshine? Therefore, the output of such greenhouses is extremely low.

Another thing is that it is not allowed to fertilize plants when planting plants in noble families. Whether it is human fertilizer or animal fertilizer, it is a sin to think about it.

But Jia Huan was different. Although he did not allow human fertilizer to be applied and felt uncomfortable, he allowed Guo Sanzhuang's family to use some livestock fertilizer to fertilize the soil.

The soil is good, the sun is good, the temperature is suitable, and there is no shortage of water. Therefore, compared with the green vegetables that are half-dead and wilted in the greenhouse in the Jiahuan house, the vegetables in the Jiahuan greenhouse are extremely lush and vigorous. Moreover, the varieties of vegetables are much richer.

Jia Huan built three large rooms for such a greenhouse.

With the watery carrots, green vegetables, cucumbers, tomatoes, purple eggplant and green peppers, Jia Huan put two...small baskets, this is the New Year gift he gave to the mansion.

Not only for the Jia Mansion, but also for the New Year ceremony he planned to give to the Duke of Zhenguo Mansion.

There are also Duke Li Guo Mansion, Duke Xiu Guo Mansion, Duke Qi Mansion, etc.

There is nothing better than this advertising method...

Since cement involves the safety of the Qin city and state secrets, it may attract the attention of the court and the military, then Jia Huan will not be able to make this business bigger again, and the future and hidden worries are too great and will be easily exploited.

As for the glass business, Jia Huan has not thought about growing it at the moment.

The reason is also very simple. With his current energy, he is destined to be unable to protect this gold-scue business.

In the original work of the Red Mansion, Ningguo Mansion is entertaining guests during the New Year. If you want to use a glass screen to support the scene, Jia Zhen needs to leave her face and send Jia Rong to borrow from Wang Xifeng.

Because Wang Xifeng's family was an official who managed overseas vassal states for the imperial court. If he wanted to come to Daqin to meet Tianyan, he would go to the Wang family first.

I think this is probably where Wang Xifeng's screen comes from.

It can also be seen from this that glass is so precious at this time.

If Jia Huan took out the glass and sold it at this time, even the people in the Jia family would not be able to sit still and come to take it.

After thinking about it, since cement cannot be made bigger and glass cannot be taken out for the time being, then let’s change the idea, use cement to build a house, use glass to make a bright window, and make a greenhouse.

Those noble families who are desperate for face will never give up their skin and try to seize the sale of vegetables.

In addition, Jia Huan also made a camouflage device for the glass window, and made a layer of duplex window frame on the inside and outside of the glass, and the window was pasted with grease paper.

If someone comes to watch, send someone to hang the oil paper window in advance...

...

"Third Master~"

"Um?"

"Third Master~~"

"Um!"

"Third Master!!"

"Ouch! Get up and crush me to death! Xiao Jixiang, why are you so heavy? It's time to lose weight!"

Jia Huan lay on the kang without any image, lazily not moving, letting Xiao Jixiang act coquettishly, responding, but not raising his eyelids.

After annoying Xiao Jixiang, she sat on her back and screamed.

After pushing Xiao Jixiang away, Jia Huan said bitterly: "Xiao Jixiang, listen to the third master, ah, this white covers thousands of chubby cuckolds, and you will lose everything! Look at you, your little face is chubby, and you will be round without bulging your face. You look like a lucky baby now!"

Xiao Jixiang ignored this. Even Aunt Zhao praised her as she grew older, and said that her face was white and red like a peach, making people want to bite! Sister Xiaoque pointed a red dot on the middle of her eyebrows, which made her look more and more festive!

Besides, the food on the farm is so delicious and sweet that you won’t lose weight!

I couldn't rob the third master during the meal. If I gave in, I wouldn't starve to death?!

With a pout, Xiao Jixiang started to act coquettishly again: "Third Master, just take me back to the house!"

Jia Huan raised his hand and knocked her eyebrows, then turned over, knocked Xiao Jixiang down, pressed her under her body, Jia Huan lay on it, letting her fight, and laughed and said, "I have told you a hundred times. Tomorrow is not possible. Time is tight, so I have to hurry. You can also take a car when you go. When you come back, I will ride a horse with Timur and rush back. The carriage will let Zhao Guoji come back by himself. What should you do then? Take Zhao Guoji in the carriage alone to bring it back?"

While resisting Jia Huan's oppression, Xiao Jixiang bared his two cute tiger teeth, wrinkled his little nose and urged upwards hard, and slowly gasped and replied: "What's the difficulty? Third Master can bring me with you when riding a horse! Third Master, don't you always shout and let us be companions in the world when riding a horse, and do you still ride a horse? You can't just shout and don't do it!"

Jia Huan put his head on Xiao Jixiang's little head. After hearing his words, he gently knocked back and thumped. Xiao Jixiang became more honest. Jia Huan snorted and said proudly: "Smell Jixiang, is the third master shouting? The third master is singing! Besides, my driving experience is only a few months old. Although I am a talented third master, I am already riding a croaker now. But this New Year's Day, we should be the first to be safe. If you are so heavy, what if you are exhausted when you run halfway through the road, what will happen?"

Upon hearing this, Xiao Jixiang slowly stretched out his little hand and grabbed the back of his head. Then a pair of caterpillars frowned. After a few thick breaths, he suddenly supported the kang with both hands and exerted force. Finally, Xiao Jixiang successfully overturned a mountain pressing on her!!

Jiao Da nodded expressionlessly and said indifferently: "The old man is going to kowtow to the old man and put in an incense stick."

When Jia Huan heard this, he was a little surprised. You, an old servant who was not surnamed Jia, also want to enter the ancestral hall?

However, seeing Jiao Da's face seemed to not want to say more, he didn't ask much and got on the carriage without asking much.

Li Wanji and Timur each rode on a horse to escort the left and right. Zhao Guoji raised his whip and threw a crisp whip. The carriage slowly drove.
