In ancient times, there were no cars, no highways, and no high-speed rails and planes, so travel basically depended on horses. The road is not a sheep's intestine road, it is the so-called official road. Even the so-called official road is just because there are many people walking, and the government pays attention to it, and mobilizes the common people or the army to renovate it every year, which is wider and smoother than other roads, and there are fewer bandits.

The so-called official road, the road conditions are not good, and the horses are dusty. Besides, where is it comfortable to ride a horse in a modern car, even in ancient times, riding a carriage was a tiring thing.

Therefore, Jiang Chengzi rode back and forth between Jinyuan County and Yizhou on horseback in the past two days, although her physical fitness was quite good, but such bumps could not bear it. So, after she went home and took a look at the gift-giving things that Yang Wang's family was tangled in, she went back to her room to sleep.

She slept in the dark until dawn.

The second day was Bai Lu. Jiang Chengzi only got up after three poles in the sun, and he obviously felt that the weather was getting cooler.

She stood on the well platform and was stunned, Yang Qingrang had come back from practice, holding a sword in his hand, and when he saw her in a daze, he criticized: "Ah Zhi, you fish for three days and dry nets for two days, if you don't practice diligently, how can you make progress?"

Jiang Chengzi said with a smile: "I don't kill the enemy." ”

Yang Qingrang thought for a while, nodded and said, "Yes." ”

"What can the eldest brother gain today?" Jiang Chengzi chatted casually.

Yang Qingrang put the sword aside, walked to the pavilion next to the well platform and sat down, and said, "Today's white dew, the weather is extremely cold, I see that some plants in the courtyard need to be moved, or do some other measures." ”

"It's not yet time for the frost to fall. Don't panic. However, there is more sunshine in this Shuzhong Mountain. The cold is quite heavy, and it may not be enough for the frost to fall, but the frost will fall thickly. Jiang Chengzi replied.

"Hmm. I thought the same thing. So I asked Uncle Chen in the stables in the morning. He is a native of this Jinyuan County. It is said that the Mid-Autumn Festival and winter in Shu come early, and you must prepare as soon as possible. Yang Qingrang said.

Jiang Chengzi only said that it had been prepared a few days ago, and those who should have moved into the room had instructed their subordinates, and those who should be counted into the cellar were also put into the cellar. As for some plants, don't pay attention to it, summer and winter withering are natural laws.

"We don't want to be greedy, we only change the natural environment a little. Don't be greedy and break the rules. Jiang Chengzi said.

Yang Qingrang nodded again and again, but he was a little absent-minded. Jiang Chengzi looked at him. I guessed that he actually wanted to ask what she was doing when she went out the night before. Although the brother and sister have only been together for less than a year, they have experienced a lot of things together and still have a very tacit understanding with each other.

"Big brother, if you don't have anything else. I'm going to prepare. Tomorrow we will enter the mountains. Jiang Chengzi was straightforward.

Yang Qingrang was forced to be helpless, and said directly: "There are no outsiders here today, and you tell me the truth, did the King of Shu come back that night?"

Jiang Chengzi didn't answer, lowered his eyes and asked, "Why does the eldest brother ask?"

"You are strategizing, and the eldest brother is ashamed of himself. It's just that we are a family, and if there is any change, the eldest brother can also make a small contribution. Yang Qingrang replied.

Jiang Chengzi lowered his eyes. said: "The king of Shu is worried about the situation in Shuzhong, so he came back secretly. You also know that the day before yesterday, he went back to Chang'an to ask for a request to go back, and coupled with the delay of Shennong's plan, His Majesty does not want him to come back for the time being. Therefore, his request for his return was not granted. Moreover, now that Qin has been here, we also know roughly what His Majesty means today, and it is better for him to be in Chang'an than not to be in Chang'an. In any case, we have to have someone in Chang'an. ”

"That's good. I'm just afraid that if he does something out of the ordinary on impulse, you will also go crazy. Yang Qingrang breathed a sigh of relief.

When Jiang Chengzi heard this, he asked with a smile: "Is the eldest brother afraid that I will elope with him?"

"You are a beautiful lady, why do you say such things? No, no. "Yang Qingrang is like a pedantic master, righteous and righteous.

Jiang Chengzi laughed at him for being too pedantic and said, "It's just me and my eldest brother talking about it in private." ”

"It's not okay to talk in private, if the wall has ears and is heard, how can it be good?" Yang Qingrang reprimanded.

Jiang Chengzi stuck out his tongue and said, "If you hire you, you will be a wife, and if you run, you will be a concubine." I won't be sober-minded and do miserable things. ”

Yang Qingrang heard this, nodded, and said, "You can be so sober, and the eldest brother can rest assured." ”

"Big brother, don't worry. This backyard matter, there is a mother to deal with. A-Niang is not a fool. You can only know a thing or two about the ancestral house, and you must not talk about it. Now, what we are bent on doing is the establishment of this institute. Jiang Chengzi advised.

Yang Qingrang nodded and said, "This is natural." Once this academy is established, if it can bring excellent benefits to the imperial court, we will not only have meritorious deeds, but also avoid participating in political battles, which is the favorite way for our brothers. ”

"The eldest brother began to prepare, and if he had any doubts, he would discuss them with me. In the past few days, I have to start the matter of going into the mountains, and I must implement this matter of finding salt mines, and make progress before the Spring Festival this winter, otherwise it will be detrimental to Gewuyuan and me. Jiang Chengzi said.

Yang Qingrang is also a transparent person, he knows the world thoroughly, nods right away, and continues to study hard.

After Yang Qingrang left, Jiang Chengzi went to the backyard to look at those precious flowers and plants, and instructed his subordinates to build sheds for winter, as well as cellars for sweet potatoes and potatoes.

She directed the excavation of the cellar, both to ventilate so that the sweet potatoes would not suffocate to death, and to maintain the temperature. Generally speaking, the group of people selected by Yunzhu are all good at farming, and listening to her point out one or two, they can immediately understand and do a good job.

After a busy day, I finally took care of the winter of the plants, which was considered to relieve my worries about entering the mountain. When it was time for supper, the servants who had been sent out to prepare the utensils and supplies returned, and everything was well prepared. At the same time, Che Hu also came back in the dust, and came to the small hall in the backyard to visit Jiang Chengzi.

"How?" Jiang Chengzi saw him come back and immediately asked.

"I was really told by the nine girls, I went to the mountains here for a few days and found a hot spring, but the scale is not large. Che Hu took a sip of the tea soup handed over by Jiang Chengzi, and told a little bit about the situation of going around the mountains in the past few days.

"Can you bring soil back?" Jiang Chengzi asked.

Che Hu put down his bag, took out some dirt from it and handed it to Jiang Chengzi. He also talked about the growth of plants around the hot spring. After listening to this, Jiang Chengzi concluded: "It seems that this area is indeed not suitable for plant growth. ”

"It doesn't matter, natural geothermal heat. We can bring our own soil, as long as we can grow fresh vegetables in the winter. Jiang Chengzi said.

Che Hu touched his head and said puzzledly: "Fresh vegetables, there is no shortage in Shuzhong in winter, so it seems that there is no need for such a lot of trouble." ”

"Naturally, there is no need in Shuzhong. But in Chang'an, in the Northland. If you have fresh vegetables in the winter, it's a rare commodity. Entering the market can get 10,000 gold, and entering the DPRK can also be described as a shortcut. Jiang Chengzi raised his eyebrows and smiled. The voice was very low.

Che Hu suddenly realized, and also lowered his voice and asked: "Nine girls are going to test in Shu, and they will go to the north in the future, and they will also make this plan?"

"That's just one of the reasons. Reason two. In the future, we will definitely go to Chang'an. I like to eat fresh vegetables. Well, the third reason is that the ground cage greenhouse we built is too expensive and not very desirable. Jiang Chengzi replied.

Che Hu nodded again and again, and couldn't stop praising Jiang Chengzi's foresight, which was really unthinkable to them as ordinary people, and immediately said that it was a great honor to be by his side.

"You are not so humble. On Investigation and Searching. Chasing the murderer for thousands of miles, I am not as good as you. You and I are friends. It's a partner, it's an equal person. But he is not a servant of this Yang Mansion. Jiang Chengzi said to Che Hu.

Che Hu shook his head again and again, and said, "You are the person who is valued by the Lord, and you are the master of Che Hu." Che Hu will never forget this. It's just that Che Hu is grateful to Miss Nine for this kindness. ”

Jiang Chengzi was not reluctant, only nodded and said, "You are also hard, go and rest and rest." ”

Che Hu shook his head and said, "Nine girls, this is not hard. The scenery in the mountains is so beautiful that you don't say you have to find it. I'm very laid-back. ”

Jiang Chengzi heard him say this, and knew that he had something to say, so he looked at him and asked, "Do you have any good suggestions?"

"Che Hu is not talented, thinking that since this matter is a secret weapon, it must not be known to too many people this time. Therefore, please be ordered to guard the hot spring test for the Nine Girls. Che Hu bowed and said.

Jiang Chengzi was originally looking for a candidate, and when he saw Che Hu taking the initiative to ask for help, he said, "Okay, even so, I'll work hard for you." ”

"The nine girls are laughing, and they can share your worries and solve problems, which is the blessing of the car and the tiger. "Che Hu gave up.

Jiang Chengzi took a sip of tea and said, "Tomorrow I will go into the mountain, and tonight I will sort out some matters for you, and then spend the money in my hand." Don't talk about it to anyone. Tomorrow morning, you come to me early in the morning, get the usage plan, and go ahead to prepare. Also, you can take the cloud that I bought on the street the day before yesterday. The boy knew how to read and let him keep track of his progress every day. ”

Che Hu got the order and went to rest. Jiang Chengzi called Xiao Jiu and asked him to count his belongings and prepare to enter the mountain early the next morning.

That night, Jiang Chengzi was writing in the study until late at night, and no one knew what the nine girls in the Yang Mansion were busy with, only that she was not busy until the third watch. Of course, Jiang Chengzi is making a list of items and a design style. She wanted to use the geothermal heat near the hot springs to experiment with greenhouse vegetables to test the feasibility of such an idea.

Of course, the only difficulty in greenhouse vegetables or greenhouse vegetables is to find materials that transmit light but do not dissipate heat. In modern times, there is such a thing as plastic film, but there is no plastic process in ancient times, and there is jade or something with this kind of light transmittance, but using jade to build a house, not to mention that the cost is too great, and it is extremely difficult to find jade that is to achieve that texture.

Could it be that you have to eat fresh vegetables, and you have to carry out the industrial revolution and make plastics or something?

His uncle, although he is a genius girl, is not an all-rounder. Where do you know so much? It's a tangled thing.

So this night, she really didn't find any suitable materials in the materials, and she was a little frustrated, feeling that this time it seemed like she was going to go down the drain. The only thing I want to prove is that in the vicinity of this geothermal heat, the greenhouse effect can be ignored, and the skylight can be opened on the roof to seal the room in the evening.

Of course, the results of this experiment were successful in Shudi, but not necessarily in Beidi. However, it is always unsteady not to give it a try, after all, there are other substances near the hot springs besides geothermal heat, which will affect the growth of plants.

Although the most important things were not solved, she still drew up a sketch and a list.

On the second day, as soon as the sky was bright, Yunzhu came to serve her to wash, saying that she had brought Qing'er and others to put the food in place, and the rice balls ordered by Jiang Chengzi were also prepared.

Jiang Chengzi combed his capable ponytail, changed into clothes and pants designed by himself, packed clothes, food, and water properly, and carried with him the sleeping bag that was designed a few days ago for Yang Wang and others to make. With a marching bag, she was too big to carry, but it made people feel as if she was about to fall down at any moment.

After breakfast, Jiang Chengzi and Xiao Jiu set off with Yao Ziqiu, and brought three servants with them, and a group of six people headed for Jiashan Mountain.

Zhuanyunzhai had already received a report that the nine girls of the Yang family would enter the mountain today, and they had set up places to greet them along the way early. Where Jiang Chengzi and his party stopped along the way, the specifications of the refreshments were comparable to those of the aristocracy, and all kinds of seasonal fruits were also available.
