my scientific age

Chapter 58 My name is Yu Hua!
Since the customer has the intention, things will be easier to handle. After a simple exchange, Yu Hua got an order for three portable lighting sources from the lovable and lovely sister Fang Yu.

A full three!

As expected of the big customer I had booked in my heart, starting with three units, 180 oceans is like one yuan and eighty cents, which is light and flimsy.

With the support of the three light source orders, Yu Hua made up his mind and did not delay much. After the equipment was delivered on the weekend, he would bid farewell to the rich ladies Fang Yu and Zhou Yuan directly.

Zhou Yuan, who was still in a position not far away, shook his head lightly when he saw this, regained his senses, and sorted out his English notes on his own. Regarding the sale of portable lighting sources, after a collective discussion in the dormitory, it was decided that Yu Hua would be in charge. worry.

And, to be honest, Zhou Yuan doesn't care much about the business of portable lighting sources. His family is rich, and his daily living expenses and pockets have never been cut off.

Mixing into Yu Hua's project is just to fit in with the group.

Well, now a little more reason to help friends.

……

Leaving the classroom again, Yu Hua took the business and happily embarked on the journey to the canteen.

The project of selling the light source system is basically stable, and Sanbai Dayang is waving to him from a distance.

Feeling happy and comfortable, Yu Hua felt that he could eat four multigrain steamed buns and two bowls of clear water radish soup today.

The reality is so cruel, Yu Hua, who has not experienced the rush and hard work of 996 in later generations, after returning to this era, still busy for money, or 007.

In essence, Yu Hua does not need too much money. In the future, he will go to the United States to study, as long as the money is enough, but for now, Yu Hua finds that he needs a lot of money in a short period of time.

Life requires money, study requires money, and scientific research projects require more money.

Leaving aside life and study, if he wants to complete the preliminary scientific research project he has formulated in his mind and develop nitrocellulose, nitroglycerin, and trinitrotoluene, Yu Hua estimates that at least [-] oceans will be needed to support him in completing such a project.

As for the oxygen top blowing technology listed as a long-term plan, the cost is even more frightening.

This era is different from future generations. This is an era of uniting to do great things. It is not enough for one person to fight alone.

On the way to the cafeteria, Yu Hua counted his current network of contacts.

After the unremitting efforts and serious management after the start of school, Fang Yu, a young rich woman, Liu Tao, a rich man, Ji Han, the main supplier, Cao Wei and Cheng Youping, who are well-known, Tan Qing, who only has 30 yuan, and Lin Wan, a big brother, These fairy students are relatively close to me, and they may become my help in the future, belonging to the circle of classmates.

Zhou Yuan, who has a wealthy family and excellent learning talent, has a close relationship with himself, and is already a friend, not a simple relationship at the same table. It belongs to the category of friends and is included in the circle of friends.

Brothers and sisters Xu Rui and Tang Yuanyuan, who are fellow villagers in Sichuan Province, are considered close circles and are worthy of trust.

There is no family circle.

In addition, it is worth mentioning that Yu Qinghe's No.20 Ninth Army and Hua Luogeng belong to the circle of contacts. The former is related to the army, and the latter is related to National Tsinghua University.

I need to work hard to manage the relationship with them. After I arrive at Tsinghua, I can form a temporary scientific research team and use the strength of Tsinghua to tackle the oxygen top-blown converter technology. Before leaving, I will leave the greatest help to the motherland.

After Yu Hua counted it, he pondered in his heart.

The outbreak of the Anti-Japanese War was imminent, and the domestic environment had no chance for him to develop, but after leaving like this, Yu Hua felt ashamed of the knowledge in his head.

Trinitrotoluene is used as a military strong gunpowder and has a wide range of uses. Whether it is used as a warhead charge for artillery shells, or as a charge for conventional weapons such as mines and grenades, all require TNT.

The comprehensive performance of black powder is too low to meet the needs of modern battlefields.

The two brothers, nitrocellulose and nitroglycerin, mean single-base propellant and double-base propellant in the field of military propellant.

A single-base propellant, composed of nitrocellulose, which can be used in the production of rifle bullets and machine gun bullets.

Double base propellant, composed of nitrocellulose and nitroglycerin, can be used as artillery charge and mortar charge.

The above-mentioned three professional technologies belonging to the field of chemical engineering explosives cover a wide range. As long as they can be successfully developed, especially simple and low-cost production processes, they can significantly increase the combat effectiveness of front-line troops in the entire Chinese battlefield.

Throughout the anti-Japanese battlefield, whether it is the front-line troops fighting in front, or the active Eighth Route and guerrilla troops behind, except for a few elite troops who can get foreign support, there is always a shortage of weapons and ammunition.

Take the No.20 Ninth Army stationed next door as an example. The No.10 Ninth Army has reached the level of 20 people. Most of the troops lack weapons and ammunition. Many soldiers can only use outdated weapons to meet the enemy. .

Once the production technology of these three types of gunpowder is available, and the knowledge stored in Yu Hua's mind can greatly improve the situation of this disadvantage on the battlefield.

If nothing else, a mine with at least one kilogram of trinitrotoluene strong gunpowder can easily reimburse a Japanese tank.

The explosive power of a grenade filled with black powder and a grenade filled with TNT is completely different.

Of course, Yu Hua deeply understands that these three technologies are actually of little significance to the domestic orthodox troops. After all, they have a serious military factory, but they have an extremely important role in the Eighth Road, which is active in the battlefield behind the enemy.

However, Yu Hua did not say that the technology was specifically developed for which party. If the National Government needed it, then it would be given, and if the Eighth Road needed it, it would be given equally, regardless of each other.

Leaving aside the three recent modern gunpowder technologies, the oxygen top-blown converter technology is the real highlight.

This is a cutting-edge technology developed for the whole of China. Once it is successfully developed, it means that the curtain of the construction of China's heavy industry will be opened.

"Phew... Come on, Yu Hua, you have no way out, you can only keep moving forward, come on." After briefly sorting out the matter, Yu Hua, who had always been optimistic, secretly encouraged himself, and his eyes showed a hint of determination.

There are still five months before the full-scale outbreak of the Anti-Japanese War, and for him today, there is still a lot to do.

Now, for the future, work hard to improve yourself, and... make money.

Become a glorious and emotional money making machine.

Quickly arrived at the cafeteria, squeezed through the crowded and noisy crowd, and came to line up behind the cafeteria line. The students around were still discussing about portable lighting sources. The boring study and life on weekdays made the lighting lamps born out of nowhere. The source suddenly became the talk of many students.

"Hey, that light was on last night, it was so bright."

"No, it is indeed bright and bright. After two years of reading, this is the first time I have experienced such a bright light in a school."

"Have you heard? That lamp was made by a science student named Yu Hua."

"Great, this child is not easy."

"Have you heard of it yet? Yu Hua said that kerosene lamps are bright and dim, which can easily hurt the eyes and cause vision loss. I didn't believe it last night. After lighting a kerosene lamp for a while, my eyes were sore. It's true."

"Does it really hurt the eyes?!"

"Of course, that's what Brother Cao and Brother Cheng said. If you don't believe it, you can try it yourself."

"It turns out that kerosene lamps can cause vision loss. My eyesight has risen to [-] degrees over the years. After taking glasses, there is no distinction between people and animals three meters away. This is a miserable situation. If I had known, it would have been better. I am proud to light a kerosene lamp, and when I think about it now, I feel like a stupid donkey."

"Students don't want to do this. It's not too late to know now. After dinner, I'll go to the second grade two and ask Yu Hua if they sell that type of lighting."

"The classmates are right, eat first and ask later."

"This classmate Yu Hua is really my savior. If he hadn't put forward this point of view, I would have been harmed by kerosene lamps, and I would definitely not read books under kerosene lamps in the future."

The classmates who were queuing for dinner were talking about it.

Glancing at everyone calmly, Yu Hua showed a smile on the corner of his mouth. He lowered his head and said nothing. When it was his turn, the team ordered four multigrain steamed buns and a bowl of clear cabbage soup. After three or two meals, they washed the dishes.

After finishing this, Yu Hua went to the third-year teacher's office in the teaching building.

……

In the afternoon, the sun is shining.

The teacher's office is located in the middle of the bottom of the concave shape on the third floor of the teaching building.

After Yu Hua arrived, the door of the office was already open, the interior was simple, there were a few desks, and the other places were empty. Mr. Ren Luo Wenguang was sitting in the innermost position on the right, holding a pen in his left hand, and was busy with his head down.

The gentleman is left-handed. Whether he eats or writes, he is all left-handed.

"Dong dong!" Seeing Luo Wenguang, Yu Hua breathed a sigh of relief, thinking that no one was there, standing in front of the door, knocked gently on the door.

"Please come in." Hearing the crisp knock on the door, Luo Wenguang, who was in a busy state, immediately raised his head, turned his eyes to the door, and shouted after seeing Yu Hua.

"Hello sir, sorry for being late." Yu Hua walked into the office, came to Luo Wenguang, and greeted him politely.

Luo Wenguang smiled and shook his head: "It's okay, sit down first, do you want to eat?"

"Mr. Hui, eat." Yu Hua sat on the wooden bench and nodded respectfully.

Hearing these words, Luo Wenguang smiled slightly and looked at Yu Hua in front of him carefully. His facial features were straight, his demeanor was calm, and there was a hint of heroism in his eyebrows, giving people a feeling of confidence but not arrogance.

Recalling Yu Hua's previous ambitions, Luo Wenguang felt a zealous expression in his heart.

Is a pillar of talent.

"Come on, this is the name change application you want. Check it out first to make sure there are no mistakes." Without too much delay, Luo Wenguang opened the drawer and took out a yellowish piece of paper with a sense of age, with a column of large characters written on it.

"Student Name Change Application"

Student Yu Hua is a native of Chengdu, Sichuan Province. He entered the school on September 24, 18. He is now 14 years old. He is a student in Class 35 of Science in the third grade of Beiping No. [-] Middle School. He ranks [-]th in the school's science scores and [-]th in the school's comprehensive ranking. , now, upon voluntary consent, apply to the school for name change.

Current name: Yu Hua.

Change name:

Change of name student signature:

The signature of the teacher at the level: Luo Wenguang
Signed by Dean of Academic Affairs: Han Yeping
Principal's signature:

After carefully browsing, Yu Hua confirmed that it was correct, raised his head to look at Mr. Ren, Luo Wenguang, and said sternly, "Mr. Hui, there is no mistake."

"Then write it. Change your name to the student and sign your current name. After submitting this application, before the first class in the afternoon, your name will be Yu Hua." Luo Wenguang took out the pen he carried with him and took off the cap. Putting it on the table, he looked at Yu Hua, and looked at the first student in this class who changed his name, with a gentle face, without the previous strictness, and exhorted.

"call……"

Hearing these words, Yu Hua's face was solemn and solemn. He stared at the student's name change application, and picked up Luo Wenguang's pen in his right hand, a warm feeling came.

Holding the pen with his right hand, he stared at the column for the signature of the student who changed his name, and wrote Yu Hua's name without hesitation.

After writing, I moved my eyes to the previous column to change the name column, took a deep breath, and closed my eyes. I recalled the past and memories of my predecessor Yu Hua, and said something in my heart, I will take your memories and dreams with you. survive.

From now on, my name is Yu Hua!
