Friday, December 5, 1625.

On the north side of the West District of Long Island, near the naval base at the mouth of the East River, next to a neat artificially transplanted pine forest covered with snow, is a closed building complex covering an area of more than 100 acres. This is the campus of the Long Island Naval Academy, surrounded by high walls around several academic buildings or dormitories, and by an iron fence gate, two guards in black winter naval uniforms are huddled in a sentry box, rubbing their hands and feet to ward off the biting cold.

In contrast to the icy and snowy outside, there is a spring-like scene in the school building. The winter coats of the Navy cadets are locked in the closet of the locker next door, and the warmth and comfort created by the hot water heating pipes make every cadet in the classroom wear only a single uniform.

Like the rest of his classmates, Yan Xianping, dressed in a black winter navy uniform, placed his military hat in the corner of his desk, sat up straight, put his hands lightly on his lap, and stared intently at the direction of the classroom door. Except for her still slightly immature body, her hairstyle was no different from that of the other female naval cadets present.

After a while, I saw an elderly female classroom dressed in ordinary clothes walking in with a smile. The appearance of the person who came surprised Yan Xianping, who already had a little knowledge of China's high-level American leaders. In today's math class, it is actually the old man Li Ping, the speaker of the House of Representatives of China and the United States!

Li Ping, who was a high school mathematics teacher before the crossing, was a "distinguished mathematics professor" at the Navy Long Island Academy, and now she personally explained a class, which made the students secretly excited.

"Today, we're going to review a set of math calculations from your lesson in a different way." Old man Li Ping smiled mysteriously, then beckoned to the door of the classroom that had not been closed, and then saw two naval non-commissioned officers walking in with a suitcase.

Two Navy non-commissioned officers walked into the student's chair corridor with the suitcase, and each time they walked by, one of them would take a palm-sized metal body from the box and place it in front of the cadet. At the same time as the issuance of this strange metal body. Two more Navy non-commissioned officers carried a larger-looking machine covered in a red cloth and placed it on the podium.

"Uh......" Tang Hannah, who was sitting next to Yan Xianping, couldn't help but let out a strange sound of surprise when she saw these two things, and several other female students who also belonged to the small characters of the Crossing Group curiously reached out and grabbed the metal body in their hands, turning around and looking at it.

"Hehe, this is a computer, everyone should be careful with it, don't fall on the ground." Li Ping smiled slightly. Uncover the cloth cover of the hand-cranked mechanical computer in front of you, "What you have in your hands is the more convenient one." ”

The mechanical computer invented by Pascal, a famous genius in the 17th century, is now appearing in the classroom of the Long Island Naval Academy in China and the United States in advance as a more sophisticated and advanced model. Its predecessor can even be traced back to Greece under the Roman Empire BC. A few girls from later generations who have crossed the small characters. As if I had seen a rare commodity, I dialed the small mechanism on the simple mechanical computer.

With this ingenious mathematical machine, one can run addition, subtraction, multiplication, and division and even more complex mathematical operations. Although far less efficient than the electronic calculators of later generations, this kind of mechanical computer, which was still active in all walks of life until the beginning of the 20th century, has made an indelible contribution to the development of human civilization as a whole.

The first batch of mechanical computers made of the first batch of mechanical computers with extremely high cost in order to ensure the accuracy of the gear hobbing inside, You Renyi, chief engineer of the General Industry Company, personally went on the horse for almost three all-nighters.

"Alright. Listen to me explain how to use it, and in the calculation process, you also need to use pen and paper to make key records. It may be troublesome to use it for the first time, but as long as you are familiar with how to use it. It will be much easier for you to do math in the future. However, today is just a tool experience, and you still have to calculate with paper and pen in your specific learning, and you can't rely too much on the computer! ”

Seeing everyone's interest, it was uplifted. Li Ping officially opened the lesson plan at this time, no matter how many of the students present belonged to the "geniuses" who passed through the small characters. A junior high school math class, which seemed extremely simple in later generations, began.

……

"Sister Hannah...... Wait for me! After class, Tang Hannah grabbed her military hat boredly, and planned to go to the pantry next door to pour some hot drinks, but just when she got up, she saw Yan Xianping walking in front of her with a red face, holding a pencil with an embarrassed expression.

It's no wonder that Yan Xianping will fail in the classroom test, for Yan Xianping, who is not used to pencils and has just learned about Arabic numerals and modern mathematics, it is a hundred times more troublesome than embroidery to solve the arithmetic problems with various "strange" symbols.

Looking at the full chest under the other party's uniform, Tang Hannah showed a mysterious smile, leaned his head forward slightly, and squirmed words that only the two of them could hear: "Not bad, the underwear I bought for you yesterday was put on?" ”

"Uncomfortable......" Yan Xianping's face turned even redder, and he quickly covered his military hat on his chest, and carefully looked left and right.

"Slowly get used to it, hehe, otherwise it will sag later." Hannah Tang smiled nonchalantly, her eyes falling on the hallway of the classroom, as if she saw someone.

"Hello instructor!"

Tang Hannah suddenly stood up and saluted behind Yan Xianping, which immediately startled Yan Xianping on the other side. Yan Xianping turned around sharply, only to find a tall naval major standing in front of him with a smile, and his eyes seemed to be looking at his chest.

In a hurry, he instantly forgot about the military salute that he had not learned for a long time, Yan Xianping was not leaving, nor was he staying, so he almost found a crack in the ground and got into it on the spot.

"Take a break. The small screen is still used to here, right? Sun Yang's sunny smile on his face carried a kind of self-discipline and gentleness as a teacher, as if Yan Xianping in front of him was his most proud protégé.

"Report to the instructor, it's okay ......"

Yan Xianping, who has gone through the "special admission" procedures of the Navy Headquarters and joined the Long Island Naval Academy of the Navy of the United States of America, has already met the instructor Major Sun Yang more than once, and is curious and frightened by this young naval officer who is said to be "outstanding in battle" in the current Chinese and American Navy. Yan Xianping's voice answering Sun Yang's question at this time was small and small, which was in great contrast with her previous personality.

"Tomorrow I will give you a formal lecture, "The History of the Development of World Navies". You can't learn these things in Daming, and you have to record them carefully on the small screen. Seeing that more students walked into the corridor, Sun Yang ended the "chance encounter" and walked away with a cool expression.

"Is Uncle Sun Lolicon?" Looking at Sun Yang's distant back, Tang Hanna muttered softly to herself, her face full of teasing smiles.

"What is Lolicon?" Yan Xianping looked curious again.

"It's just that you care very much about the students, and you are being taken care of!" Tang Hannah pursed her lips, pulled open the hairpin that was coiled around her long hair, shook her beautiful blonde hair, and walked towards the pantry, and several male students passing by on one side cast their admiring glances.

"Focus? Dad also often taught that teachers are like fathers, and I naturally respect them. ”

Muttering inexplicable words, Yan Xianping took out his coat and walked through the corridor between the teaching building and the dormitory building alone, intending to go to the dining hall for dinner. was only halfway there, and suddenly found that the little maid Xiaoyu was actually wrapped in thick winter clothes, carrying a pitiful bag under the snow pine tree outside the gate of the college.

Three steps and two steps over, the guards at the door saluted with guns, and after Yan Xianping returned the salute so-so, he pulled his little maid to the temporary reception booth on the side.

"What are you doing so far away on a snowy day?!" Looking at the little girl's frozen red face, Yan Xianping felt a little distressed, "Didn't Elder Zhong Ge arrange for you to go to that national junior high school to study?" ”

"Woo, miss, can you not go." The little maid in a winter school uniform and thick cotton robe cried with a look of grievance, "I am the only one in a room of young children, and I am ashamed to death." ”

"This former Song Hua United States attaches great importance to educating the people, if you are illiterate, won't you lose the face of my Yan family?!" Yan Xianping made a frightened expression, with his hands on his hips.

"But...... Hey, Miss, you ......" was about to argue, and suddenly found that today's miss was different from the past, and the little maid secretly pointed her hand at Yan Xianping's chest.

"Uh...... Don't be ashamed! Yan Xianping hurriedly turned around, blocked in front of him with his hand, blushed again, saw that there was no one outside the pavilion, and quickly put his head to the little girl's ear, muttering.

"How delicate and unseemly I am when I am that woman, it turns out that it is nothing more than that!" The little maid suddenly realized, and her face turned red.

"The academy has a rule that family members are not allowed to visit on non-weekend holidays, so don't come in the future, you know?" Seeing that the little girl's love was getting better, Yan Xianping took out the identity of being the master of the house, "Study hard, take care of the old Zhong Ge and the old lady at home, and in more than a month, it will be the winter vacation, and I will come back to accompany you then." ”

"Miss, why do you have to join this Huamei Sailor Society, or you should study with me? If there is any discomfort, the slave can also take care of one or two. "Seeing that the young lady is going to enter the Huamei Sailor this time, the little maid is very incomprehensible.

"Hmph, I want to see what kind of magic this gorgeous navy has, which can make Uncle Luo fear like a tiger!" Yan Xianping raised his head unconvinced, and turned his gaze to the academy, "That woman can learn, why can't I learn?!" ”

Seeing that her young lady was so strong, the little maid didn't say anything anymore.

In order not to let the little maid run so hard and return on an empty stomach, Yan Xianping wrapped a "Taixiyi meal" from the college cafeteria and handed it to the other party at a very fast speed. As a result, a sweet and hot lunch made the little maid suddenly have the idea of coming over for a stroll if she had nothing to do.
