The last semester of the senior year passed quickly, the four of them faced separation, Arlene also broke up after graduation, but she looked very open, pulled the three people in the dormitory to drink with her all night, and didn't say a word about her boyfriend after waking up. Ah Fang, Ah Lin and Ah Mei did not return to their hometown, but shared a small suite in the city to start their work and life. After all, they had frequent contact with Sixi before, and then maybe because they were busy with work, they gradually became less, after all, their pressure was much greater than Sixi's.

During this period, the No. 2 suspect Zhuma still couldn't be contacted, even if Sixi asked his parents, there was no contact information. Brother Bing never appeared again, and so far her mission has made no progress.

Sixi didn't go out to look for a job, but he opened an online store by himself, specializing in selling potted plants, the world's online sales platform seems to have just begun, and most people don't accept it very much, so there is basically no business at present. Sixi is not worried, and he is also very open-minded, if he can't sell it, he will put all the potted plants in his parents' restaurant.

Although parents do not object to their children staying at home, but at least they still clean up and dress themselves up every day, but every time they come back, they see an unkempt Sixi and they can't bear it, and finally in the second month of Sixi home, Dad proposed to let Sixi go out for a walk and see the great rivers and mountains of the motherland!

Sixi agreed, and the first stop aimlessly chose the inland grassland in the northwest region - Shanzebei grassland to enjoy the scenery of the grassland.

After getting off the plane, I got on the bus and finally arrived at my destination with the dust on my head, and the grassland was so beautiful that the descriptions that appeared in the texts could be seen here. Dragged luggage to the hotel, called the hotel is not suitable, it is a particularly large yurt-like house, but the facilities are complete. The proprietress is a talkative, through the talk of Sixi to understand that the travel is better to go forward, the scenery is better, and there is more fun, don't go to the north, the grassland in the north is not as big as before, now the wind and sand are big after all, the yellow sand has eroded a lot of grassland, the government has been unable to curb the erosion of the yellow sand for so many years, and now the chamber of commerce has begun to organize manpower and material resources to start sand control together.

In the evening, there was a sandstorm and yellow sand flew all over the sky, and soon it was completely dark. The locals seemed to be used to it, and before the sandstorm was completely submerged, the cattle and sheep rushed into the pen and closed the doors and windows.

Early the next morning, the yellow sand was about 1 foot thick at the door, and everyone was accustomed to cleaning up and opening the door, and the normal day life began. Sixi was depressed in her heart, remembering when she was sent by Chuanbai to make trees, when her eyes were yellow sand all year round, and she suddenly wanted to go to see the scene of sand control, so she asked the proprietress how to go. The proprietress thought that the little girl was curious, so she warmly invited Sixi to go with them, and today they were going to send supplies to the sand control base, which was actually water and food.

In the car, Sixi learned that the Grassland Chamber of Commerce is divided into two areas, the north and the south, the proprietress and their area is divided into the south area, which is responsible for supplying food, daily necessities and water, and the north area is responsible for the replacement of tools for sand control and the purchase of saplings, which rotates once a year, and it is now in its fifth year. Now we can only delay desertification, sandstorms like yesterday are small, in the past few years, sandstorms will basically be blocked by yellow sand, people can only climb out of the skylight to clean up slowly, plus this year's drought, maybe this year's situation is not very optimistic.

When I really arrived at the place, it was said that the base was actually a large courtyard 3 stories high. Seeing that there were seven or eight people who were busy shoveling sand and clearing the road, the thickness of the sand here was much deeper than that of the hotel, about half a person deep, and the gate of the base could not be opened, so everyone got out of the car to help clean it up. After moving the supplies into the house, Sixi asked to see where they worked.

A black, thin and thin young man named Zhang Yuan took Sixi to go, and after going, he saw that there were 2 people with hats cleaning up the wheat straw, and the two were laying the wheat straw into a square, and two people were holding shovels to press the laid wheat straw down, and compacted the surrounding sand, so that the wheat straw was firmly erected on the sand, which formed a physical barrier grass grid for sand control. Zhang Yuan said that a batch of large wattles would have been shipped today, and they were planted in the square, but because of the sandstorm, it was estimated that they would come later.

Si Xi looked at his bronze complexion, and could see that this was the result of a long period of wind and sun, she was actually quite touched, when she became a tree, she was in the desert, could it be that it was also planted by the sand control people? At this moment, Si Xiting wants to stay here and plant trees and control sand with them, at least to fulfill his dream of survival for a lifetime. But she also knows that this is unrealistic, her parents have not explained, the task has not been completed, although she is now passive and slacking off, it does not mean that she has forgotten the most important purpose of coming to this world.
