Chapter 121 Impolite Questions!

The voice is not high, but calm and normal, like a narrative.

But such a simple narration made Lin Wan fall into silence, only to feel the heat all over her body, and the blood flowed faster, as if it was about to boil.

For Yu Hua, getting admitted to Tsinghua University and going abroad is a constant goal.

It is true that, as long as there is no accident, Yu Hua will become a university professor by virtue of his current performance and talent. According to the timeline, he will even become a professor at Southwest Associated University in the near future, and he will become famous in domestic academics. In addition to this, they can also use their own wisdom to study various applied technologies and military weapons to help the country resist Japanese aggression and gain fame.

However, Yu Hua still chose to go abroad.

For no other reason, because this is the future.

If the motherland wants to rise strong and prosperous, it will never be separated from science.

Of course, there is another way, and that is to stay at home for development, and then go abroad after the Anti-Japanese War and World War II are over.

However, the time and opportunities left for him at that time were too little.

Before World War II officially broke out, Yu Hua still had the opportunity to go to the United States, or even to Europe, to expand his knowledge and fill in the basic parts that he lacked. Only in this way can he do more.

In the same sentence, Yu Hua never thought that as a traveler, he was superior to others, and he could come up with cutting-edge technology casually. Scientific research requires foundation, advanced technology requires foundation, and the advanced knowledge and technology recorded in his mind are more. Countless fundamentals are needed to lay the groundwork for real value to come into play.

If he was already a college student before the time-travel, if the person who was transmigrating was not him, but a doctoral or graduate student from the University of Science and Technology of China, he might not have to bother to go abroad at all.

However, things are not if.

He is the lucky one chosen by 3000 million compatriots.

"Will there really be such a day? You should understand how difficult it is to realize your wish..." Yu Hua's words echoed in his ears, feeling the will and emotion from Yu Hua, Lin Wan took a deep breath and opened her eyes. Looking at Yu Hua, she pursed her lips, her words contained a trace of hope, a trace of hope, a trace of... fear.

She was deeply attracted by the scene described by Yu Hua, but, with her strong rational thinking, she couldn't believe it was true.

As one of the very few highly educated women in China, although Lin Wan is a student, she has her own understanding of the whole China and the world, not to mention that she has another identity that she has never told Yu Hua.

There is no roar of Japanese planes in the sky, there will be no more concessions and troops stationed in Peiping, Chinese diplomats will no longer protest in tears, and there will be no foreign warships on the Yangtze River, which belongs to China's inland river. This era of humiliation will surely end.

Is such a scenario really possible?
"meeting."

Yu Hua looked up at the blue sky, his deep and vast eyes stared at the scorching sun hanging in the east, then lowered his head, a smile appeared on his face, and said: "I understand, very clear, but I will definitely do it. , surpass everyone. Of course, I also wish Jinyu that you surpass everyone, I believe you have this ability."

The words are still peaceful, seemingly arrogant words, but they are full of persuasion, and people feel a sense of trust when they hear them.

At this moment, a ray of sunlight fell on Yu Hua, his eyes were full of light, and his face that was not particularly handsome showed a unique temperament.

Yu Hua's blessings came from her ears. Looking at Yu Hua in the bright sunshine, Lin Wan was startled for a moment, her heartbeat subconsciously accelerated by a few points, she had to admit that at this moment, Yu Hua was filled with a fatal attraction. force.

Also, the compliments that were basically enough to hear in the past, but now they are particularly pleasing to the ears, hitting the heart.

It seems that she is also a layman.

Feeling the change in his heart, he couldn't help but smile: "Jin Yu, thank you for your blessing."

"I thought you would doubt my thoughts just now, how do you feel now?" Yu Hua asked with a smile.

"As you said, foreign advanced technology and knowledge is the key to the prosperity of the motherland. We need a vigorous revolution to save China, and we need advanced technology and knowledge to make China strong. Jin Yu agrees and supports your point of view. ."

Lin Wan smiled: "As for the mood, I am refreshed and full of fighting spirit, as if there is a flame burning in my heart, your ideal is so great, then Jin Yu can't fall behind, she should study harder and not be pulled too far by you ."

"Let's encourage each other, cherish the time, and come on." Yu Hua also smiled, raised his right hand, and put his five fingers together, revealing the palm of his hand.

"Crack!" In a flash, a clear and loud voice came out, and the little hand with a slightly calloused palm was touching Yu Hua's right hand.

After the high five, Lin Wan took a step back and stared at Yu Hua with eyes as clear as gems: "I'm going to the library, do you still owe me a meal?"

"Remember." Yu Hua was startled, and immediately remembered the meal he promised in the library, and smiled.

"After graduation, Quanjude Roast Duck, I will answer your impolite question before." Lin Wan took a step forward and stood in front of Yu Hua, looking straight into Yu Hua's eyes rather boldly and intently. After speaking, she blinked playfully. He blinked, smiled, and turned to leave.

The breeze came, the blue silk fluttered, facing the warm sun, Lin Wan left a back, and walked away.

That rude question?
Yu Hua silently watched Lin Wan's back go away, and thoughtfully, of course he knew what the 'impolite question' was in Lin Wan's mouth.

refuse, or...

agree?

I have to say that he did like Lin Wan a little at the beginning, but Yu Hua wasn't going to get involved too much in the affairs of his children before he accomplished his goal.

It's good to have it, and it's okay to not have it.

However, Lin Wan is the most crucial existence among all Yu Hua's existing friends, even the rich Zhou Yuan and Tan Qing are not comparable to her.

Because Lin Wan has another identity, which is the link that he intends to contact the Eighth Route Organization as Zhang San.

"Forget it, why do you think so much... Do math, do math, do math." After thinking about it, he shook his head lightly, and Yu Hua silently chanted a refreshing spell.

The whole person walked back and forth, and soon arrived at the school gate. After checking the documents, he left No. [-] Middle School and went to the appointed place.

It didn't take long for Yu Hua to arrive at the agreed location. Due to the delay in chatting with Lin Wan on the way, Xu Rui had already arrived and waited quietly.

"Sir, the prices of vegetables and rice in Beiping City have risen by 20% these days. In addition, the No. 250 Ninth Army captured a Japanese spy in Dongcheng the day before yesterday, but he was later released due to government reasons. The situation is basically normal. Regarding the gun Ruizi has already inquired about the matter, a German shell gun with ammunition costs 500 yuan, 300 rounds of bullets, and [-] French currency."

"250 yuan ocean... Temporarily buy a shell gun."

After listening to the regular reports on the situation in Peiping City, Yu Hua nodded. At the end, he entered Erpang about the price of the shell gun, and the corners of his mouth twitched slightly. It was so fucking dark that the price was about three times more expensive than the imported price. The price of a batch of German original Mauser pistols purchased by Zhongzheng last year was around 80 French dollars. Now the black market is asking for 250 yuan and 300 French dollars.

The whole person took a deep breath and decided to buy an emergency first.

Having a gun and not having a gun are not the same thing. No matter how expensive it is, you have to buy it for your own safety.

However, it is worth noting that the speed of the devaluation of the French currency. The purchase price of a German shell gun on the black market is 250 yuan, or 300 French currency, and the exchange rate between the two has reached 1:1.2.

Inflation rate further increased.

Supplies seem to be getting scarcer, and the smell of war has come.

"Yes." Xu Rui nodded and noted.

"In addition, here's a check for 640 yuan. You can get it from the Beiping branch of Jiaotong Communications, and then exchange it for silver dollars or gold bars as quickly as possible." Yu Hua took out the latest check on his body and handed it to Xu Rui, explaining.

The French currency cannot be kept, not even for a moment, the silver dollar is stable, and the gold bar is the best.

"Yes."

"Also, this is a purchase list of equipment and materials. The equipment and raw materials listed above must be purchased as soon as possible and placed in the workshop that you rented last time. In addition, you will build a laboratory based on the workshop. This is a design drawing, you can ask someone to help, I want it to be completed within a week."

The entire equipment and material procurement list is composed of beakers, lard, cotton, sulfuric acid, nitric acid, soda ash, alcohol ether solvents such as ethylene glycol, propylene glycol and ether, diphenylamine, alcohol lamps and other raw materials and basic equipment. The overall difficulty of procurement is Simple, alcohol ether solvents and gunpowder stabilizer diphenylamine are slightly more difficult. The content list directly points to Yu Hua's next plan - establishing a chemical laboratory and completing the development of three gunpowder technologies.

Lard is rich in glycerol, cotton contains the most cellulose, diphenylamine, camphor and graphite in natural plants, which are the basic materials for the manufacture of nitrocellulose.

Sulfuric and nitric acids, as well as lard, are the base materials for nitroglycerin.

With these two energetic materials, single-base propellant and double-base propellant can be fabricated.

After these days of study, the smart Xu Rui has been able to understand the design drawings and entrusted him with the task of establishing a small chemical laboratory, which is basically no problem.

The small chemical laboratory will be built in the temporary workshop where everyone used to manufacture Qiming brand lamps. After the completion of the mission, the entire workshop will be rented by Yu Hua alone.

"Yes." Xu Rui took the purchase list of equipment and materials and design drawings and put them in his arms.

After explaining the matter, Yu Hua prepared to return to school and reminded Xu Rui, "Okay, that's it for now, I'll go back to school first, Ruizi, take care of your own safety."

"Ruizi understands." Hearing Yu Hua's concern, Xu Rui showed a smile, looked left and right, and then left.

Yu Hua didn't delay too much, turned around and left. After a while, he returned to school and continued to study the theory of real variables. The chemistry laboratory was to be established, and the main subject mathematics could not be left behind.

……

March passed quietly, and at the beginning of April, a real sense of spring emerged and enveloped the city of Beiping.

I don't know when, the big trees on the campus and the city streets pulled out twigs, and a touch of green suddenly appeared, embellishing this city without light pollution and sandstorms.

A ray of hope, symbolizing hope, enveloped Peiping, which was on the brink of war.

However, for the vast majority of ordinary people in the middle and lower classes, with rising prices and frequent shortages of materials, they who just want to fill their stomachs do not know where their hope comes from.

Entering April, the Japanese troops in the Fengtai area, which belonged to the Chinese Garrison, suddenly became calm and stopped conducting military exercises. The No.30 Seventh Division, which was in charge of stationing near the Marco Polo Bridge, breathed a sigh of relief. Take this matter to heart. The confrontation and stalemate in the Pingjin area for more than two years, although there were some contradictions and conflicts during the period, even reached the level of open fire, they all ended in negotiations between the two sides.

exercise?

You can play it however you want, I don't care.

Army Commander Song Zheyuan felt that the total strength of the Japanese Army in the Pingjin area was only about 20, and that the No.29 Ninth Army had a total strength of [-]. The military intelligence still did not attract his attention.

Exercise against the Lugou Bridge, so what?

With his subordinates Qin Dechun and Feng Zhi'an there, there was no trouble.

However, this incident aroused Zhang Zizhong's vigilance.

"The Japanese suddenly stopped the exercise, and the minister was quite uneasy. Judging from the Japanese invaders' desire to destroy China, they could never stop just now. This move should be to paralyze our army's will and eyes, and they are actually doing something secretly. Unspeakable things."

In a Buick car driving from Tianjin to Tsinghua Park, Zhang Zizhong, who was sitting in the back seat, held a cigarette in his right hand and said to Tian Hong next to him with a worried look, "Unfortunately, my words and information did not cause any problems. The commander is concerned, in his eyes, I am still Zhang Zizhong who is close to the Japanese."
