Chapter 174 Teaching Children is Difficult
"Greenhouse?" Baoya looked confused.
The same went for Yun Chenglu and Jingzhen. None of the three children had ever heard of such a new term as "greenhouse cultivation".
Nan Xuan nodded and asked, "Why don't vegetables and flowers grow in winter?"
"Because it's too cold, the vegetables and flowers are all frozen to death!" Baoya said.
"Yes, so to put it simply, a greenhouse is a warm shed for the vegetables or flowers we want to grow, allowing them to grow."
"Oh~" Baoya and Yun Chenglu looked as if to say, "So that's how it is."
It's actually possible, why didn't she think of it? It's amazing.
In fact, as early as the compiled history of China, ancient people had already eaten out-of-season vegetables.
The "Taiguan Garden" recorded in "Book of Han·Biography of Zhao Xinchen" was the special supply base for royal vegetables at that time.
However, Taiguan Garden uses "Yunhuo", a flameless combustion method, to increase the room temperature indoors to a temperature suitable for vegetable growth.
There is also the record of Fire Dao Yu Yang in the Book of the Later Han.
However, both methods are too time-consuming in terms of manpower, material resources and money, and are not realistic to use on ordinary people like the Yun family.
Apart from these two methods, introducing hot spring water and artificially creating a temperature suitable for vegetable growth is not very realistic. The Yun family lives in the village, unlike him and Jingzhen who live in seclusion in the mountains. Bringing in hot spring water is even more difficult than building a greenhouse.
After a brief thought, Nan Xuan decided to use the method that was closest to modern greenhouses.
He remembered that in this fictional country of Dakang, cloth was not a particularly expensive material and almost everyone in an ordinary family could afford it.
As long as a layer of oil is applied on the cloth, it can become airtight. When exposed to external sunlight, it is not easy to scatter and lose temperature. Its function is similar to that of the plastic film used to build greenhouses today.
After careful consideration, he told Baoya his ideas and concepts. However, this was just a preliminary conception and had not been put into practice.
As for the actual implementation, Nan Xuan, who had already drawn up a rough plan for the greenhouse, tossed it directly to Bao Ya: "Here, this is roughly what I'm thinking. As for whether it will succeed, you'll have to figure it out on your own when you get back."
Practice is the only criterion for testing truth. He taught me the method, and the rest is up to the little girl herself.
Jingzhen was no longer surprised by his unreliable nature. Seeing Baoya still leaning over the table and studying the blueprint seriously, he stepped forward, patted her shoulder and said, "I can help you figure it out."
Baoya raised her head from the drawing, met Jingzhen's serious gaze, and nodded happily: "Okay!"
Yun Chenglu twitched his lips a few times: ...
What he wanted to say was interrupted.
However, seeing the smile on Baoya's face, he didn't say anything else.
In the past, Jingzhen had no contact with them. He felt that he was Baoya's brother, so of course he had to help take care of everything.
But now, Jingzhen has become Baoya's senior brother, and he seems to have no reason to refuse.
However, looking at the happy and harmonious scene of Jingzhen and Baoya getting along with each other, he always had the illusion that his own little rabbit was taken away by the big bad wolf.
The three children practiced kung fu very hard in the afternoon. When the sun set in the evening, Nan Xuan called a halt. After filling a basket with big peaches for Baoya and Yun Chenglu, he sent Jingzhen to take them down the mountain.
The setting sun cast a red glow on the horizon. Yun Chenglu walked in front with a large basket of peaches on his shoulder, chattering to the lonely king as he walked. Baoya was followed behind him by Jingzhen.
In winter, the trees lose all their leaves, leaving only bare branches.
Baoya walked down the winding path of Huya Mountain and saw people queuing up to fetch water at the west end of the village in the distance.
Suddenly, she remembered what she heard the two servants from Heishui Village say when she was fetching water with her second uncle that day.
"Brother Xiaojing, do good people also do bad things?"
Jing Zhen didn't know why she suddenly asked such a question, but he still said patiently: "Yes. No one is perfect. Even a good person can't do nothing bad in his life."
Baoya didn't understand: "But if a good person does something bad, can he still be considered a good person?"
"Then, what kind of bad thing did he do?" Jing Zhen frowned.
"Well, he... killed someone."
Jingzhen was shocked to hear Baoya say the word "murder" so easily.
He picked the man up, his expression even colder and more serious than usual: "Killing, what do you mean?"
Baoya repeated to Jingzhen what she had heard the two servants say.
Jingzhen looked at her innocent eyes and breathed a sigh of relief. So that's how it was.
Baoya is too young to understand the true meaning of life and death. She only vaguely knows that killing is a very serious and bad thing.
"Just remember that Duan Jiang is a bad guy." Jing Zhen said directly.
"But will the bad guys also share food with us?" Baoya still didn't understand.
"He distributed the food to you for a purpose. He wanted to get the information he wanted from you."
Baoya blinked her eyes: "He is looking for his brother who ran away from home."
Jingzhen: ...
He took a deep breath. "But the servant he killed was innocent. He's a murderer, and he's giving you food. Do you still think he's a good person?"
Baoya's eyes widened immediately, and she shook her head like a rattle, saying in a clear and firm voice, "No!"
After hearing what Brother Xiaojing said, she felt like she couldn't eat the two bags of food at home!
"That's right. You have to remember that there's a line between good people and bad people. Once you cross it, you can only be considered a bad person. Even if you do a good thing, you can only be considered a bad person who did a good thing."
"Oh." Baoya nodded, not quite understanding.
Seeing that the little girl finally understood, Jingzhen secretly breathed a sigh of relief. It turned out that teaching a child was so difficult.
I don’t know if I ever gave my brother this much trouble when I was a child.
"Brother Xiaojing, Prince Heshun defeated the bandits, so why did the emperor punish him?"
Jingzhen: ...
He suddenly felt the urge to pull Nan Xuan over and give Bao Ya a lesson.
Anyway, that guy always has a lot to say when it comes to big principles.
"Victory over the bandits is a good thing, and he should be rewarded," Jing Zhen said word by word, "but he also did other things that harmed the people."
"What's that?"
"He secretly stole the grain reserves from the Huzhou people's granaries. Those were the things the people relied on to save their lives during famines and floods."
When talking about this, Jingzhen narrowed his eyes slightly, with a terrifying cold light in his eyes.
"Then he really deserves to be punished!" Baoya clenched her fists and spoke indignantly.
Jingzhen's eyes curved up at her cute appearance.
In fact, Baoya contributed a lot to Ye Jinghua's demotion to the border.
That night, he went back and admitted his mistake and made peace with Nan Xuan. The two of them discussed a good strategy of collecting evidence and exposing Ye Jinghua, and successfully turned the situation around.
Thinking of this, he reached out and gently pinched Baoya's little face, and said softly: "Thank you."
"Huh?" Baoya was confused by his sudden thanks, "Why are you thanking me, Brother Xiaojing?"
