Next.

The morning sun rose, shining on the wooden sign at the entrance of the ancestral hall, a few big characters of Lujiacun Primary School.

"The outside world is so prosperous, but Lujia Village is so backward." Qin Yu held the scroll and looked at the sun above his head and looked at the village again, and said in his heart, "The great cause of the motherland's teaching is a long way to go!" ”

"Only when the volunteer teachers work tirelessly and hard will they have the opportunity to go out of the mountains and see the outside world in the future and be in line with civilization. Otherwise, it will continue to lag behind, and it will be the same for thousands of years. ”

"I am just one of the thousands of teachers in the motherland, cultivating the flowers of the motherland in the mountains."

"The cognition of Lujia Village is still in ancient times, and the villagers will be surprised to find that it is now the 21st century. If they saw a car or plane outside, their jaws would drop. ”

"How wonderful is the world? The sun in the sky is the same, but it shines on the poor mountain villages and the high-rise buildings of the big cities outside. ”

"The life of volunteer teaching is a lonely ......"

Walking into the classroom, the seven students were already sitting neatly.

"Today, the teacher is going to conduct a thorough test for you today, in order to see how your real level is." After Qin Yu finished speaking, he sent the four volumes that he had written last night to the four sons of the village chief's family.

The other three children are illiterate and do not have to take exams.

There is no ink printer in the village, and the rolls are all handwritten by him, unlike when he wants to print a few sheets outside.

The rice paper was brought by the village chief, and the pen was also brushed. In this remote and isolated mountain village, he has long been unable to expect any good teaching conditions, and everything is simple and useful.

"I'm almost the same as the people in this village, and I'm back in ancient times, which is called following the local customs." He complained in his heart.

Examination?

Hearing Qin Yu's words, the faces of the four princes showed joy: the time had come for them to show their talents.

Their level of education is already very high, at least they are a showman. Everyone looked forward to Qin Yu sending the volume down, and immediately wrote a proud one, and then got the praise of Mr.

However, when they saw the scroll, they were all dumbfounded.

The first problem is a one-dimensional equation, 5X-5=0 to find X,

The second question is the calculation of scores.

Question 3: Please write down Newton's three laws of mechanics.

Question 4: Please translate the following sentences: howareyou, finethankyou, andyou!

Question 5: Please balance the following chemical equation: CaCO3==CaO+CO2↑ (high temperature)

……

"What kind of fairy questions are these?" The four princes were dumbfounded.

"Is this a book from heaven?" Zhu Di said in his heart.

The four of them immediately looked at each other, you look at me, I look at you.

"Take your time, give you half an hour." Qin Yu took out his mobile phone and looked at the time. Now his phone is almost out of battery, so he has to save some time, but fortunately, the quality is good, and the standby time is long. Get out of the classroom.

"Big brother, do you know these questions?" After the teacher left, Zhu Di asked Zhu Biao, among the four brothers, the old university is the best.

"No, it won't." Zhu Biao said, "Master Song hasn't taught it before." ”

"I seem to have flipped through these numbers on an ancient book in Wenyuan Pavilion, the ancient book is dusty in the corner, and no one usually looks at it, it belongs to the extremely unpopular kind, I remember that it said that these symbols were transmitted from the West." Zhu Fan pointed to the Arabic numerals on it and said, "But I don't know what it means to add a cross and a bar after the number." ”

Arabic numerals have been passed down in the Song Dynasty, but at that time, everyone used to count chips, so they were not promoted. Although it is not widely used, there are sporadic records in some ancient books.

"Mr. Qin's knowledge is really knowledgeable, he knows such a part-of-the-way thing, and he still takes it out to test us. And he seems to be dozens of times more esoteric than what is recorded in that ancient book, and the numbers in the ancient book have no forks and crosses. Zhu Chun said.

"What about the third question? Ask us Newton's laws of mechanics, who is the surname Niu? What do the laws of mechanics mean? Zhu Biao said.

"I haven't heard of that surnamed Niu, is it Confucian, Taoist, or Legal? But I'm sure he must not be well-known, and if he is more famous, it will definitely be recorded in the book. Zhu Chun said, "As for the laws of mechanics, I am even more confused. ”

"There is also a fourth translation, which is completely a book from heaven."

The fifth question is even more strange, do these distorted symbols belong to Taoist charms? I only know the two words of high temperature in the back, high temperature, is it talking about alchemy? ”

"I think it's about alchemy!" Zhu Chun affirmed.

"Mr. Qin's knowledge really covers three religions and nine streams, I am completely convinced today!"

"Before, I thought that my knowledge was good, after all, I had read a subset of scriptures and histories for more than ten years. I didn't expect that in front of Mr., I was blind. Zhu Biao sighed.

While the students were talking about each other, Qin Yu was wandering outside and had no intention of invigilating.

Suddenly, I saw several figures in the distance, walking towards the school.

Seeing this, Xu Da immediately went to greet him.

"I've seen the village chief, ma'am." Xu Da stepped forward and saluted.

"Father." Xu Miaojin said softly.

"Be quiet, don't expose it." Xu Da reminded, "The village chief said before that I was a bachelor, so it was impossible to have children, and when you saw me in the future, just call me Uncle Xu." ”

"My daughter takes the order." Xu Miaojin made a blessing. My father has become an uncle, and it always feels weird.

"Xu Da, what does Mr. Qin mean by writing a few words Lujiacun Primary School on the wooden sign at the entrance of the school?" Zhu Yuanzhang asked curiously, "We have only heard of private schools, universities, and Hanlin Institutes before, and we have never heard of the name of primary school." ”

"Mr. Qin's knowledge is unfathomable, how can I, a big boss, figure it out?" Xu Dadao, "But I dare to guess that it should refer to the children's school." ”

"Makes sense." Zhu Yuanzhang said

"What's the matter with that flag?" Queen Ma pointed to the red flag flying over the school and asked.

"You two don't ask me, I don't know a single word. If you really want to know, just ask him. Xu Da said.

"What Mr. Qin is doing is really weird everywhere! It's completely confusing. Queen Ma sighed for a while, "Is he magical in itself, or is it because we are short-sighted?" ”

"We think it should be similar to the general flag used by generals when they fight, embroidering the general's surname or the totem representing the team on the flag. The first is to facilitate the identification of friendly forces, and the second is to deter the enemy. Zhu Yuanzhang said.

"Makes sense." The crowd nodded.

"It's okay for Mr. Qin to hang the flag." Zhu Yuanzhang said, "After we go back, we will make an order, but any place where you can see this red flag is a forbidden place, and any bandits and thieves are not allowed to cross the thunder pond for half a step." ”

"Those who violate the order will punish the Nine Clans!"
