Cup of rice to raise benefactors, fighting rice to raise enemies, Lin Fan still understands the truth of this sentence, he has already done what he should do, and he has done enough, and no matter how much it should be, it may have the effect of raising enemies, so it can only be done in moderation, not to mention that he can't do too much with his own strength, and the rest depends on the attitude of the highest authority in Datang, whether it is good news or bad news is all in Boss Li's thoughts.

Boss Li's thoughts Lin Fan can't be controlled, so the only thing he has to do is to live a good life in the moment, and ignore what is going on outside the window, as for the final result, there is no need to wait, how the wheel of history should go is not something that he can decide now that he is just a small person who is a county man.

He is an optimistic person, he never cares about things that are not within his control, the things in front of him are enough for him to worry about, the two sons that Lao He handed over to him still don't even know how much one plus one equals, which can break Lin Fan's heart.

In desperation, she had to hand over these two goods to Ling'er to deal with, her majesty and her intelligence were enough to deal with these two people.

Today is the last practical class of the Lin Academy, after this class will be on the summer vacation, although the Lin Academy was founded by Lin Fan himself, the teacher is also the only one, he is also a teacher of mathematics, just like the later twenty or thirty years ago in the remote mountain village did not have a good school, often a person with a little knowledge acted as the enlightenment education of all the children in the village, teaching children of all ages.

No matter what kind of school it is, the holidays are always necessary, and the students are very happy that there is a summer outing before the holidays, and the fresh excitement makes them very active in preparing the things they should bring, and gather at the door of the big family early.

For this summer camp activity, Lin Fan spent a little more money to rent a few carriages, so that these forty people followed him, not like a trip, more like an angry youth demonstrator, the Tang people don't know what the demonstrator is, but they will put on the hat of gathering crowds to make trouble.

However, there are seven or eight carriages for carriages, the mighty out of the Anhua Gate, the Mingde Gate is not daring to come out, this gate is connected to the Vermilion Bird Street, if such a vast team is slow on the Suzaku Street, it will be surrounded by inexplicable officers and soldiers, it is good to meet good officers and soldiers, and there is no chance to explain when it comes up when it is bad, and it is useless to directly encircle and suppress the knife, and it is useless to call the sky at that time.

It is very cool to walk on Suzaku Street, which is more than 150 meters wide, and seven or eight carriages feel spacious when they walk sideways, but they don't dare to do this, Lin Fan, who wants to live, can only go out from Anhua Gate.

Deducting more dangerous places such as Yashan and Yushan, there is nothing particularly interesting near Chang'an, so where to play has become a more serious problem, from the first carriage to the back, I asked almost everyone's opinion, the answers are very rich, and there are all kinds of things, which makes Lin Fan even more headache, too much but more difficult to choose.

After thinking about it, I finally considered that everyone did not have much food with them, so lunch became a problem, so I proposed to play by the river, and maybe find something to eat here.

Chose a relatively close riverside and took it down, the children happily played in the river and had a water fight, He Da is the head of the child, with He Er and another child to form a team to challenge everyone here, of course, except for Ling'er and Lin Fan, these two people he dare not provoke.

Some people are afraid that He Da will be wet and dare not say anything, silently stay away from them, and individual stubborn people are not so easy to bully, and fight hard, with one enemy and three, the two people who act as the vanguard of the other party are wet, and they are also wet...

It can't go on like this, watching the sun go up, Lin Fan shouted loudly, and these children's shoes obediently stopped in place, waiting for the teacher's orders.

"Lunch time is coming, now everyone stops all water fights, start fishing now, whoever catches more fish, you don't have to do your homework this summer, hehe, if you are the last, the homework will be doubled!"

After all, students are still afraid of exam-oriented education, and when they hear their homework, they all mention that they are full of spirit to deal with the next test, although they don't want to use this kind of exam-oriented education method, but Lin Fan can't think of a better way, and this custom in later generations will be passed on and compared, maybe after thousands of years of evolution, this system will undergo qualitative changes.

Ling'er has always been very quiet here, maybe she is a girl here, and because she can't play with those bastards, she always sits quietly next to Lin Fan, looking up and thinking about the practical class to be taken today, she is so quiet when she is trying to improve, once she is out of school, she is like a wild horse that has escaped, no one can be tethered.

The boring Lin Fan felt even more bored not long after watching the students' fishing competition, no one talked to him, Shan Xiong was not good at words, he only liked wine, and he had no mobile phone to play, so he had to snatch the wine gourd in Shan Xiong's hand and drank a few sips, and lay down to bathe in the summer sunshine quietly, and his eyes were covered with a layer of cloth and he entered the dark world, and it didn't take long for him to fall asleep...

When he woke up, he had put two big fish in front of him, these two big fish were caught by He Da and He Er, the two were reluctant to eat, they only ate small fish and shrimp, and others couldn't eat if they wanted to, even if the children older than him were majestic, they refused to leave it to their respected teacher.

Touched, these two goods finally inherited his father's genes in terms of etiquette, the fish was roasted by Ling'er, roasted very finely, very seriously, there was no burnt place, I slept and my stomach was just hungry, and I grabbed one of them and enjoyed the preferential treatment of my classmates・・・・・・

The last class of this semester in the Lin Academy will be held in Gaoshan, a class specially set for Ling'er, in this regard, Lin Fan is not ashamed to feel that he is a very competent teacher, if he gets the name of an honorary teacher in the future generations, it should not be difficult.

Ling'er has never believed that two spheres of different sizes and the same mass will fall from the same height at the same time, she has always believed that it is different, and it has to be proved by practice, Lin Fan knows that he can't do this kind of experiment in reality, but this little girl has to prove it, so it's better to play with her.

Choose a high mountain that is not high, and replace it with stones if there is no sphere, He Da weighed two stones of roughly the same quality with a scale, and climbed up the mountain with a smile while holding the two stones, which was the happiest thing for him to be reused by the teacher.

Under Lin Fan's shout, He Da let go of the two stones, no matter what the result was, Lin Fan immediately asked to redo it, and just taught him to let go at the same time, but these two goods just couldn't be done, fortunately, it was muddy under the mountain, otherwise he had to find the stones again.

After testing it three times, it was finally done, and the time was obviously different, and when she saw this result, Ling'er was so happy that she almost jumped up, shouting that the teacher was wrong.

"What's wrong, don't you see that there is a big difference in the size of these two stones, the shape is so different, the air resistance must be different, the acceleration is no longer gravitational acceleration, can the falling time be the same, I told you earlier, the conclusion is that in an ideal state, there is no resistance, only gravitational acceleration.

What is an ideal state? It's our imaginary state, how can this state actually exist, so no matter how many experiments you do, it's the result of the current situation, but you can't beat the truth to death with this kind of experiment.

Study your homework well during the summer vacation, and if you don't understand this simple physics at the beginning of the school year, you should never come to class. ”

A stinking scolding made the scene quiet, Ling'er lowered her head and twisted for a while, and it didn't take long as if nothing had happened, and she smiled and pulled Lin Fan's arm and asked long and short questions.

Seeing such a scene, He Da, who was standing on the high mountain, finally realized how to make the teacher happy・・・・・・
