Past history, present reality.

With the continuous sound of guns and guns in the distance, the Lugou Bridge Incident, which symbolized the full-scale war of resistance, finally broke out.

On time, on time.

When the national calamity fell and the chaos came, Yu Hua knew what a catastrophe it was. However, for the people of Peiping, the sound of guns and guns was somewhat used to it, just like the Fengtai incident that broke out because of a lost army horse. The vast majority of people in Peiping have experienced dozens of conflicts, large or small, between the 29th Army and the Japanese army. At the beginning of the Marco Polo Bridge Incident, they only believed that there was a small-scale conflict, and the Japanese would not launch a large-scale offensive.

However, this time - the story of the wolf!
The blood in his body accelerated, and an inexplicable anger came out of his heart. Yu Hua calmly felt the emotional and physical changes. After standing quietly for a few minutes, when his emotions and physiology gradually returned to normal, he turned around and left the balcony and returned to the office. .

Turning on the light, sitting in front of the desk, taking out the math notebook, and turning to page 188, Yu Hua stared at the contents of the notebook quietly, which is the research content of elementary proving the prime number theorem.

Calm down, study.

Unreasonable anger is a sign of incompetence. Yu Hua will not allow his subjective emotions to impact his brain, thereby affecting his rational thinking and goals.

It sounds cold-blooded, but as a traveler, he has to do it, and he is willing to do it.

He did not use a thinking computer, but just studied in a conventional way. As he continued to study the profound and logical prime number theorem, the anger in Yu Hua's heart gradually disappeared, and his mind became clearer and more rational.

After a whole day of research yesterday, the oxygen top-blown converter project has achieved phased results. The Thomas alkaline converter, which is the main body of steelmaking, has been developed and the three pieces of the puzzle are all in place.

Continuous oxygen production, top blowing oxygen, and the main body of steelmaking are the three-in-one technology of steelmaking in the field of iron and steel smelting in 1937. After mastering the three major technologies, it means opening the door to the terrifying productivity of [-] million-ton annual steel production.

The open-hearth steelmaking method, for national forces, has a productivity limit of only tens of millions of tons.

The oxygen top-blowing converter steelmaking method means that a country's annual output limit can be raised to the [-] million ton level or even one billion ton level.

On July [-], the Lugou Bridge Incident broke out.

On July [-], the oxygen top-blown converter technology was successfully developed.

At 11:30 last night, Yu Hua and Professor Zhuang once again opened a substitute wine with cold white, and clinked glasses and drank.

Of course, the door is open. The goals of 1940 million tons and [-] billion tons are still too far away. Yu Hua's requirements are not high. Before [-], the annual output of steel in the base area reached [-] tons, which would be enough.

Based on the current scope of the base area and the number of talents, the annual output of [-] tons of steel in three years is already the limit.

As for the annual output of one million tons of steel in three years, Yu Hua is not crazy. This thing is not called progress, but leap forward.

Time passed slowly, the sky gradually became brighter, the sound of guns from the southwest became more intense, and the two sides seemed to have hit a real fire.

Because of the sound of guns and guns, Tsinghua University lost its former quietness and peace. Many students who were going to go home for vacation seemed to feel a little uneasy.

Today is the last day of Tsinghua University's admissions exam. Tomorrow, the whole school will arrange for students to go home for the summer vacation and report to the school at the end of August.

"The prime number theorem is indeed very interesting. If you want to pass the elementary proof, you must reverse your thinking and completely abandon the influence of advanced mathematical knowledge. Don't worry, the academic speech is about to start." The draft on the table, nodded lightly.

Just then, suddenly, the office door opened.

"You boy, did you stay up all night again last night?" Professor Zhao Zhongyao appeared, and when he saw Yu Hua sitting at the desk, he was slightly surprised and asked.

Yu Hua shook his head, and replied: "No, I got up at 45:[-], professor, the gunfire has been going on since last night, do you know what happened?"

"Pay attention to your health and don't stay up late. The 29th Army fought with the Japanese. To be precise, the Japanese attacked Lugouqiao. This is today's newspaper. Take a look. The battle at Lugouqiao was very fierce. The Japanese seem to want to repeat the Fengtai incident. Seize the last external passage in Peiping."

Hearing this, Zhao Zhongyao cared about Yu Hua's body, then changed the subject, stepped forward and put a newspaper in front of Yu Hua, and said in a deep voice, "I don't know if the 29th Army can withstand the pressure from the Japanese."

The 29th Army could withstand it, but Song Zheyuan couldn't.

Yu Hua sighed in his heart, and picked up today's Peiping Daily with both hands. On it was written a bold column title, "Japanese aggressors are blatantly invading my territory."

At ten o'clock in the evening on the 29th of this month, the Fengtai Japanese army asked to enter Wanping County for a search on the pretext that a Japanese soldier was lost during the Marco Polo Bridge exercise. The Jixing Cultural Regiment fired more than a hundred rounds of artillery to attack, and our soldiers fought back. The battle has not yet ended.

"If the Lugou Bridge falls, I, Peiping and Tianjin will be in danger." When Yu Hua carefully read the Peiping Daily, Zhao Zhongyao had a serious face and slowly gave his own analysis: "The location of the Lugou Bridge is extremely important, adjacent to the Ping-Han Railway, and controlling the Lugou Bridge is equivalent to controlling the Lugou Bridge. In order to control the Ping-Han Railway, the Japanese army will present a strategic situation of substantially encircling the Ping-Tianjin area."

Although Zhao Zhongyao is a nuclear physicist, he has no lack of understanding of the military field. After all, he is one of the few cutting-edge scientists in China.

"Professor, as students, what should we do?" Yu Hua read the newspaper with a serious face, showed Zhao Zhongyao what a student should look like, and asked for advice.

Zhao Zhongyao shook his head and said: "Wait! Neither you nor I can do anything about this kind of thing. After the frontline battle is over, according to the usual practice, we will enter the negotiation stage. The only thing we have to do is wait for news from the 29th Army. Don't do stupid things. It's impossible."

"Students won't go to the parade." Feeling Zhao Zhongyao's warning and serious gaze, Yu Hua smiled bitterly and responded.

Parade and assembly, the characteristics of the times, Yu Hua supports and admires those students who dare to march, but will not participate.

He has more important things to do.

"That's good." Zhao Zhongyao instructed: "I won't conduct the test today, you can rest well."

He didn't want Yu Hua to participate in the parade. It was too dangerous. This kind of genius with top talent can only serve the country to the greatest extent if he devotes himself to the field of scientific research.

"Okay." Yu Hua nodded.

Professor Zhao Zhongyao brought news of the Lugouqiao Incident to Yu Hua early in the morning. Not long after, another news came. At [-]:[-] a.m. on July [-]th, the famous organization in history declared a telegram to the whole country.

Every newspaper office, every organization, every army, the Chinese Kuomintang, the Kuomintang government, the military committee, and all compatriots across the country!
At ten o'clock on the seventh day of this month, Japan is at Lugou Bridge...

The entire telegram spread to every corner of China, informing the situation of the Lugouqiao Incident. The influence and significance of this telegram are very huge. Almost at the same moment, the eyes of all China focused on the Lugouqiao in Beiping.

Anti-Japanese!

Carry out the holy war of self-defense against Japan!
When the organization brought the news of the Lugouqiao Incident to the whole country, on the other side, Yu Hua received a second not-so-good news.

"Student Yu Hua, unfortunately, due to the Lugouqiao Incident, the academic speech on asymmetric cryptography prepared by the school for you today will be temporarily cancelled." The assistant principal visited and stood in the office, telling Yu Hua about the academic speech Notice of Temporary Cancellation.
