Chapter 160 Eight thousand oceans!

doubt.

Yes, when the middle-aged teacher saw the answering process of the first question of the calculation problem, a doubt arises in his heart, because the whole answering process is not just a simple 'solution', nor is it a random answer like copying the calculation problem. , but real problem-solving proofs and mathematical formulas.

You can tell right from wrong in math, you will never lie, and you can tell at a glance whether you answer indiscriminately or not.

The handwriting is beautiful, the proofs are concise and sufficient, the formulas are complete, and there is no misunderstanding of mathematical knowledge points.

The solution process seemed pleasing to the eye and extremely comfortable.

There is something!
Condensed in his heart, the middle-aged teacher suddenly felt that something was wrong, his face was serious, his eyes were fixed on Yu Hua's math test paper, and he carefully reviewed it.

There was silence in the classroom, and the students were not affected in any way, answering questions silently.

With the passage of time, the anger on the face of the invigilator who was actually a lecturer in Nankai disappeared, gradually turned into surprise and shock, and was finally replaced by praise.

Everything, like the dry land ushering in the spring rain, draws out the green and rejuvenates.

calm.

The middle-aged invigilator teacher gradually became calmer, and he never imagined that he would encounter such a thing this time as an invigilator.

A student actually completed the math test paper within ten minutes and got a perfect score!
Yes, full marks!
As a lecturer in the Department of Mathematics, he clearly knows the final score of Yu Hua's test paper. Even if he is to mark the test paper for the strictest teacher, he must give full marks.

After a long time, it turned out that I had misunderstood other students...

The point is, this is still a full-mark test paper.

"This, this test paper... You really only took ten minutes?" The middle-aged invigilator looked back, took a deep breath, and stared at Yu Hua with an elegant smile on his face, breaking the long-silent atmosphere. Some asked intermittently.

"Mr. Hui, yes." Yu Hua smiled like a gentleman, but did not ask how his exam papers were, embarrassing the invigilator.

This kind of thing is possible, but not necessary.

The middle-aged invigilator got the answer, nodded, his face gradually became serious, he didn't care about his identity, and apologized to Yu Hua in public: "This classmate, sir, I'm really sorry for blaming you, I will review this matter..."

The words are sincere and serious.

Wrong is wrong, he will not fool this matter because of his 'sir' status.

"Sir, you don't have to do this, it's just a misunderstanding. Students do the questions fast, and they like to sit after finishing them. The joint entrance exam is important now. Please go back and supervise the students." Yu Hua shook his head and explained.

The middle-aged invigilator heard and knew that this was the step handed by Yu Hua. He was silent for a second, and nodded: "Okay."

After he finished speaking, he turned and walked towards the podium.

The students around looked at the teacher who had suffered some blows, and shook their heads helplessly. As soon as the matter started, they knew the result.

This foreign school teacher suffers because he does not understand the internal situation of the fourth middle school.

This is a mythical figure who published an article on arithmetic in the Tsinghua Journal with full marks in seven subjects.

Yu Hua folded the test paper again, sat quietly, and fully enjoyed the leisure time during the test.

In the classroom, peace is restored.

"Boom!"

Time passed, two and a half hours passed, and the bell rang to symbolize the end of the exam.

All the candidates stopped writing and stood up. After the invigilator collected the test papers and left, the second math subject of the joint entrance examination was announced.

After the math exam was over, many students in the classroom couldn't wait for the answering session. Some people packed up their belongings and left quickly, preparing to review the four sub-subjects of biology and party justice.

In fact, the subject arrangement of the Peking Joint Entrance Exam is highly similar to that of later generations. On the first day, Chinese literature and mathematics, and on the second day, there are four secondary subjects and English. The main reason is that the joint entrance examination refers to the university recruitment system. The entrance examination is the successor of the college entrance examination in the Republic of China.

"Tomorrow, there will be science, comprehensive and English. After the test, I will call it a day."

After the test, Yu Hua packed up his things, left the third test room, and set foot on the way to the cafeteria, thinking as he walked: "When the results of the joint entrance examination come out, I will have a lot of free time, and I can use this time to work on the Seven Pagodas. I have completed the preliminary research and development work, but the funding problem has not been resolved.”

After the end of the joint entrance examination, Yu Hua has a lot of free time to carry out the research and development of the seven-tower device.

In essence, the seven-tower plant for sulfuric acid manufacturing is not difficult, and the preliminary design and key technology Yu Hua was completed at the end of April.

The only problem now is money.

"After the college entrance examination, ask the angels to borrow money."

Yu Hua thought for a while and made a decision. After the joint entrance examination, he would go to the predetermined angel investor.

The college entrance examination was just around the corner, and Yu Hua had not disturbed Lin Wan, Zhou Yuan and others before, and now the time was right, it was a good time to borrow money.

As for how to pay...

Emmm...

Why should I pay back the money I borrowed?

Well, just kidding, when the seven-tower device is successfully developed, Yu Hua will transfer the technology to every 'angel investor' without reservation.

In peaceful times, Yu Hua would use technology to make money.

In times of war, technology must be used to enhance its war potential.

"What are you thinking about?" At this moment, a familiar and tactful voice suddenly came out of her ear. Lin Wan came to her side at some point, carrying a schoolbag, with a light smile on her face, and she was in a happy mood. appearance.

"It's a very important matter, Jin Yu." Hearing the voice, Yu Hua regained his senses and turned to look at Lin Wan, one of the potential angel investors, with a gentle smile on his face.

Among the several potential angel investors, Lin Wan, who is the representative of the red organization, is undoubtedly the best choice. Yu Hua plans to gradually reveal his talents and talents to Lin Wan, and contact the red organization as his true identity.

Of course, Zhang San, the royal vest, is not in a hurry to reveal it.

Hearing these words, Lin Wan asked curiously, "Do you mind revealing it? Personally, I'm more curious."

"I'm going to ask you to borrow money." Yu Hua looked around, no one else was present, slightly approached Lin Wan, and whispered.

Co-author, is this the 'important thing'?
Hearing the word "borrowing money", Lin Wan was stunned and helpless. She couldn't laugh or cry. She looked at Yu Hua with her gem-like eyes, and said, "Are you still short of money? I remember that the school waived your tuition fees, and you still have 100 yuan per month. Yuan Scholarship."

"Very short, the gap is at least 8000 oceans." Yu Hua nodded seriously and said solemnly.

Upon hearing this number, Lin Wan was stunned: "..."

"What's wrong?" Yu Hua asked.

"Baqian Dayang, are you trying to buy a murderer to kill someone?" Lin Wan returned to her senses, her interest was even stronger, and she asked curiously.

Eight thousand!

Rao was Lin Wan, who had lived among the students of No. [-] Middle School for a long time, and was also taken aback by this number.

Eight thousand oceans, by no means a small amount, is an astronomical sum for any contemporary family.

Why did Yu Hua borrow so much money?
"Kill someone..."

Yu Hua rolled his eyes and sighed in anger, and then patiently explained the technology to the best angel investor: "This money is used for the research and development of a chemical technology, and I am going to improve the western sulfuric acid production process, based on the tower method. A new type of sulfuric acid production device, the output is 1 times that of the old production process, 700 cubic meters of volume can produce 22 tons of sulfuric acid per day, and the use of steel instead of lead material, if this technology is successful, it will be of great help to the country, I will It's called the Seven-Tower Device."

"Seven-tower device?!" Lin Wan lost her voice.
