The two chatted for a while, and Lin Han asked, "Mr. Lu, what do you think of the prospects of online education? If your teaching video can be promoted on the Internet, I think it should have some beneficial impact." ”

Teacher Lu muttered: "Frankly speaking, I am not very optimistic about online education, at least at this stage. ”

"Schools and classrooms naturally have their own unique characteristics, or atmosphere, which is something that is difficult to replicate on the Internet. ”

"I believe that there are many teachers who are better than me, and there must be relevant teaching videos circulating on the Internet. However, excellent online education resources have not been widely disseminated, and it is not even easy to find. ”

As he spoke, he pointed to the few books that Lin Han had just given him, and said, "Just like these books, although they can be read for free on the Internet, there are still very few people who read them on the Internet. After all, the Internet is highly open and free, and education and learning must be somewhat compulsive and purposeful after all. ”

Lin Han thought for a while, and then said: "Anyway, there are more high-quality educational resources on the Internet, which are beneficial to the society. ”

"Vientiane has plans to promote online education, and I think your classes are very efficient, so I would like to ask if you plan to put the teaching content on our platform?"

Teacher Lu nodded: "Of course it's okay, anyway, I don't have to work hard." You can come and record it at any time, and I can send you the teaching materials. ”

"That would be great. Lin Han said, and then smiled, "Actually, I think you may be the most powerful teacher." ”

Teacher Lu laughed, and his ruddy face was also a little complacent.

After a while, he asked, "By the way, Lin Han, you are also twenty-six or seventeen years old, and you are not married yet?"

Lin Han touched his nose: "Ah, not yet." ”

"Now that you've got a successful career, I think it's time to think about starting a family. Teacher Lu persuaded, and then said half-jokingly, "Speaking of which, when I saw you and Luo Xuan for the first time just now, I did feel like a match, but I didn't expect to look away." ”

"Really fake ......" Lin Han was a little embarrassed.

Teacher Lu waved his hand and said, "Forget it, don't talk about this." Young people have young people's ideas, so I'd better not give advice. ”

The two chatted for a long time, and the topic talked about major events such as education, and there were also many trivial things, such as some anecdotes and anecdotes in Qinglin County back then.

When he learned that Qinglin County Middle School was about to move into Qingnan and had a good future, Mr. Lu couldn't help but show a look of relief and happiness, and his tone of voice was a little eager.

At the end, Teacher Lu looked at the time, got up and said, "I have to go to teach, I can't talk to you anymore, let's talk about it when I have time." ”

Although Principal Zeng just said that he had arranged for a substitute teacher, Lin Han knew that with Teacher Lu's temperament, it was impossible for him to substitute for him unless there was an urgent matter that could not be escaped.

So of course, Lin Han didn't stay, so he sent Teacher Lu to the class together, and then returned to the car, in the car, Luo Xuan had already been waiting for a long time.

"How's the talk?" Lin Han asked.

Luo Xuan handed over a document: "Well, it's all written on it, mainly donations for poor students, as well as book donations, and canteen improvements." ”

Lin Han looked at it roughly, nodded a little absentmindedly, but a sentence suddenly popped out of his mouth: "That's right." ”

"What's the matter?" Luo Xuan pulled her hair.

“…… It's nothing. ”

Lin Han seemed to want to say something, so he turned around and went in the direction he came.

……

A few days after returning to Yulin City, Professor Yu Jian of Chongqing Jiaotong University rushed over and officially joined the "Shaanxi Provincial Desert Reconstruction and Construction Committee" and participated in the planning of the restoration plan of the Mu Us Desert.

Almost with Professor Yu Jian, of course, there is also the legendary miraculous "desert adhesive", which was commissioned by the Shaanxi Reform Commission to work overtime to produce and airlifted a batch of goods.

At this moment, looking at the "desert binder" powder flowing out from between his fingers, Lin Han couldn't help but show a little surprise: "This is the desert binder......

"Desert binder" is a gray-brown powder with a texture similar to that of flour, which seems to be quite ordinary. Anyone who sees it will probably find it difficult to associate it with such a miraculous effect as "turning sand into soil".

Professor Yu Jian stood aside and said, "Essentially, the composition of soil and sand is similar, and the chemical difference is not the key difference. ”

"The real difference between soil and sand is mainly in two points, one is that there is a stronger binding force in the soil and the sand does not, and the other is that the soil has rich organic matter and the sand does not have ......"

After a pause, Professor Yu continued: "With this binder, if you scatter it in the desert, as long as there is water, you can make the sand and gravel obtain a binding force similar to that inside the soil, and structurally turn sand into soil. ”

Lin Han nodded and asked, "In other words, through the desert binder, the desert can be repaired into a structure similar to loess first, and then the second restoration can be carried out to make it a real soil for plants to grow normally?"

Professor Yu thought for a moment: "You can think so. ”

Lin Han nodded.

Desert binders are used to "bond" the sand of the Mu Us Desert into an inferior soil structure similar to loess.

Then, a second restoration can be carried out in the same way as the previous restoration of the loess, so as to achieve a complete transformation of the desert.

After the desert restoration is completed, the desert of Yulin City is gone, and the first small goal of the "Shaanxi Provincial Desert Reconstruction and Construction Committee" is completed, and it can be explained to the organization.

Professor Yu Jian lifted his glasses and asked hesitantly: "Mr. Lin, can I ask again how your artificial rainfall was successfully implemented?"

Lin Han smiled: "I can't say much about this...... Professor Yu, you are waiting to witness the complete restoration of the Mu Us Desert. ”

……

The problem of water, of course, still depends on the generosity of the people of Outer Mongolia.

Although this move is suspected of demolishing the east wall and making up for the west wall, on the whole, it is still beneficial to the natural environment. As for the slight loss of Outer Mongolia, Lin Han could only express his sympathy mentally.

A few days later, in the southern part of the South Gobi Province of Outer Mongolia.

Ochirbat, a truck driver in his early forties this year, was driving down the highway and couldn't help but look a little dazed when he arrived here.

Not long ago, he "met" the mysterious man here, the Chinese man who made him shudder and whose strength was like magic.

Ochirbart was still a little unsure whether he had actually met that person, or if it was just a hallucination or a nightmare, after all, the encounter was indeed a bit terrifying.

He shook his head, ready not to think about it anymore.

Let's hurry over to this gloomy place......
