On the 6th, Tang Yaoyao finished the exam, and it is said that she can pass the rest except for one subject where she met a perverted bald invigilator.

On the 8th, Cheng Yan also finished the exam.

Both of them had never traveled alone before, and in the face of this trip that required a whole day of driving, they seemed to pay special attention to it and began to prepare early.

Tang Yaoyao ran to Cheng Yun a day in advance to ask questions, most of which were questions such as what to pay attention to and what to bring. Cheng Yan didn't say anything, but she hurriedly packed her luggage, but everything she thought might be useful was stuffed into her suitcase, and she had to turn it out and check it every once in a while - sometimes she took one thing in, and sometimes stuffed one thing into it. She will also secretly struggle with what clothes and shoes to wear for a long time.

Cheng Yun looked at them like this, and secretly felt funny, but he didn't say anything.

Some things are called experiences because they have to be verified by their own experiences. Some can be taught, while others can only be experienced by oneself.

On the morning of the 9th, Cheng Yan went home and took Cheng Yun's camera, loaded several lenses, and fiddled with it all day.

Daoba can't go, and they can't even go to the photography paradise, cloud road, and holy land along the way, so they can only choose Jiuzhaigou.

However, the icy and snowy scenery of Jiuzhai in this season is also a unique in the world, comparable to a fairy tale world.

They bought tickets for the morning of the 10th, and set off from Xinnanmen Station at 8 o'clock, and if the road is clear, they will have to sit until 5 or 6 o'clock in the afternoon, and if the road is heavily covered with snow, they may have to touch the dark.

The two little girls were so excited that they couldn't sleep all night.

They got up at six o'clock the next morning, and when they went downstairs after washing, they saw that Cheng Yun had prepared breakfast for them and put it on the coffee table. It's a simple egg fried rice with a poached egg spread out on top and a glass of milk. And Cheng Yun was dozing off on the sofa with his back.

Sensing that the two were approaching, Cheng Yun woke up, glanced at them with half-squinted eyes, pulled away a smile and said, "Get up so early? ”

Cheng Yan frowned and glanced at the coffee table: "Didn't you tell you last night not to get up this morning to cook for us?" ”

"Our family has severe motion sickness, you have to sit in the car for a day, how can you do without breakfast!"

"Let's just buy something to eat outside!"

"Yes, brother-in-law, you slept so late last night, and you got up so early in the morning, so cold...... Brother-in-law, are you going to move me to death and inherit my Steam account?"

"Eat quickly, talk less nonsense, and when you're full, you're not so prone to motion sickness. Cheng Yun said, "Rice is more anti-hunger, otherwise if you buy something to eat outside, you will be hungry when you sit until ten or eleven o'clock." And the bus will not open the meal until it travels to a fixed place, and you will starve to death if you don't faint to death when the time comes. ”

"Well, isn't it easy to vomit when you're full?" Tang Qingying was stunned.

"Nonsense. ”

"Oh, thank you, brother-in-law. ”

"Hurry up and eat!"

"Oh. ”

The two of them ate quickly, threw down the plate, and walked out with a large box.

"Gone. Cheng Yan turned back to him.

"Brother-in-law, bye-bye. Tang Qingying smiled sweetly.

"Okay, pay attention to safety on the road, and you have to eat if you get motion sickness at noon. Especially you, Cheng Yan. Cheng Yun waved his hand, looking at their two boxes, and couldn't help but feel funny.

"Got it. Cheng Yan glanced at him, seemed to notice his smile, and suddenly felt a little embarrassed.

In fact, they only go for a few days, and they don't need to bring so many miscellaneous things at all, or even a small bag for each person...... But just in case, they just shoehorned 10,000 into violence.

Soon, the two got into a taxi and left.

Cheng Yun retracted his gaze at this time, although he felt very sleepy, but calculating the time, it was almost time to make breakfast for the others.

……

Without Cheng Yan, who always runs to his room, either spying on him when cooking, or embarrassing little Lori, and without Tang Qingying, who is always by his side with his brother-in-law and brother-in-law, Cheng Yun rarely feels a little clean, but he also feels a little lonely inexplicably.

After breakfast, he went back to squinting. In the afternoon, he should have learned fighting skills from Yin Nuxia, but he also pushed it away.

He made his way to the nearest electric tricycle store.

In eight days, General Lee should be back.

In less than ten days, he was going to help General Lee prepare everything he needed.

Cheng Yun walked around until five o'clock, visited three electric tricycle stores, and he felt that the kind of electric tricycle that carried people looked quite comfortable and should be very comfortable to drive.

What General Lee, however, needed was three cargo wheels.

The cargo capacity should be as large as possible, and the body should be as small as possible, otherwise Cheng Yun would not dare to guarantee that he would be able to bring it over - Yin Nuxia's baby arrow seemed to have a very average performance.

In the end, Cheng Yun bought a family cargo tricycle at a price of 4,000 yuan, and asked the merchant to use a truck to deliver it outside the city.

He then returned to the hotel empty-handed.

Then, Cheng Yun was about to start preparing the seeds of the crops for General Li.

This one is easy to solve.

Direct Taobao!

You can buy the best seeds.

The highest yields are, of course, root and tuber crops, almost all potatoes, sweet potatoes and sugar beets. Among them, potatoes and sweet potatoes are the most economical, grow well, are easy to survive, have relatively low soil requirements, are rich in starch and even sugar, and are easy to store. Although the yield of sugar beet seems to be a little higher, the moisture content is too large, and Cheng Yun only bought a few dozen kilograms.

He bought hundreds of kilograms of potatoes and sweet potatoes.

Both of these things have their own advantages, but they are more suitable for dealing with times of famine.

Later, he searched on Baidu to see if there were any other crops suitable for General Li to bring back, and he could buy some of them.

After buying crop seeds, Cheng Yun also spent a few hundred yuan to buy a solar charging panel on Taobao, ready to be installed on the tricycle when the time comes. This kind of charging pad is usually not very useful, because it charges too slowly, and it has to be exposed to the sun for many days in a row before it can be fully charged. It can only be seen occasionally on the roof of a courier tricycle – they are used to add a little bit of range.

But with this thing, at least it won't make the tricycle a mere ornament when it runs out of electricity.

General Li basks in the sun for a few days, at least he can still open.

Although Cheng Yun felt that an electric tricycle was not very useful in the context of such an era, he really couldn't think of anything else he could do for General Li. It's not expensive anyway.

After that, Cheng Yun was idle and idle, so he simply thought about it, so he bought some books for General Li that he might use, including knowledge of agriculture, physics, chemistry and military affairs.

There are also some more special ones, such as "Individual Weapons", "Modern Firearms Encyclopedia" and the like, he hopes that these books can give General Li some reference and inspiration in the aspect of "making firearms", at least let him avoid some detours!

Cheng Yun tried to find a book on materials science for General Li, but he quickly gave up - perhaps it was the difference in the basic elements of the world, and the performance of the weapons materials in General Li's world seemed to be more powerful than the various modern alloys of the earth, not to mention that they also had various means of opening and hanging.

At this time, there is still some space left on the tricycle.

Cheng Yun was going to wait for General Li to come back, he might need some equipment or something, and he would also load it on the car when the time came.

Until Cheng Yun closed the webpage, it was already very late.

"I've been watching it for five or six hours! I said why does my cervical spine hurt so much!" he rubbed his sour eyes, stretched again, and felt that there should be no more guests at this time, so he turned off the equipment and went upstairs to sleep.
