On June 20, the 19th year of Tianwu, the world's first hot air balloon rose in Chengtianmen Square.

This hot air balloon, with a circumference of 33 meters, was built by the Ministry of Works, made of pasted paper-based cloth, and the seams of the cloth were buckled with buttons, which were repeatedly tested by Xu Mingwu and named "Zhaoyang Princess".

This naming, the meaning of showing love is self-evident, marking Xu Ershao's official entry into the battle for the captain of the horse.

In front of the Chengtian Tower, Emperor Zhu Cihong, Emperor Tianwu, together with Empress Xu, several princes and princesses and tens of thousands of Beijing citizens, visited the lift-off performance of the Zhaoyang Princess hot air balloon.

This time, Xu Mingwu also put in a lot of effort, he personally boarded the ball, lit a fire under the balloon with straw and wood, and drove the hot air balloon to fly in the air.

This performance flew for half an hour, flew over half of Nanjing City, and finally landed on the Qinhuai River outside the city, stunning the whole city and ending perfectly.

The people are happy, the princess is shy, the emperor is happy, Xu Mingwu is also excited, I feel that there is a drama in the matter of the princess!

In the end, Xu Mingwu was commended and awarded the title of Academician of the Royal Academy of Sciences.

Huangming Times opened a special page to report on this matter, and there was an exclusive interview with Xu Mingwu, he knew that this was a reporter paid by his father Xu Qingshan to pay for the purpose of whitewashing the bad effects of the street fight with Miss Qi.

Happy times are always short-lived, and Xu Mingwu officially moved out of the Pingyang Marquis Mansion and settled in the Royal Academy of Sciences.

The Royal Academy of Sciences is located in the eastern part of the city, in an area with several national universities, and the buildings are built according to royal specifications, like a small palace complex.

There are not only Chinese-style buildings in the courtyard, but also a few Western-style houses, I heard that there are foreigners living in them, scientists dug up from Europa by the Ming Dynasty, and a few are very familiar names to Xu Mingwu, and they are the big guys in the textbooks of later generations.

Xu Mingwu specially inquired if there was a guy named Newton, but unfortunately, no. (Newton is still a sophomore at Cambridge University, which will be arranged later)

But what shocked him was that there was a big guy in the physics department, who was called Niu Pen! Or the discoverer of the law of gravitation!

Xu Mingwu wanted to visit this Mr. Niu Bi with excitement, but unfortunately, Mr. Niu was very busy and did not have time to see him.

The big guy is really the big guy, not a mortal! Xu Mingwu's heartfelt appreciation.

On the second day after entering the Royal Academy of Sciences, word came that the Dean wanted to see him.

Xu Mingwu was overjoyed, and he had been thinking about how to get close to the eldest princess of Kunxing, but he didn't expect her to take the initiative to come to the appointment, which is really good!

Coming to the palace where the dean's office was located, he followed the guide into a large and quiet hall, a large office to be precise.

"The dean's inspection hasn't come back yet, so you should wait a while." After the leader finished speaking, he left.

Xu Mingwu took a deep breath and carefully looked at this bright hall, the furnishings inside were extravagant, the ceiling was high, the floor was wooden, the floor-to-ceiling windows were glasswork, and the exquisite curtains were pulled on both sides, and the sunlight poured into the whole room.

In the middle of the hall is a large carved writing desk, on which are placed the four treasures of the study, several green bonsai, and the same table lamp of the Qianqing Palace.

When he was in the Qianqing Palace before, Xu Mingwu didn't pay attention to the principle and battery of the lamp, he took a closer look and found that the wire of the lamp was connected to a small pool, which contained copper and zinc sheets.

Xu Mingwu suddenly realized, this is the ancestor of the battery, this pool of water should be salt water, using chemical reactions to generate a stable power supply, which can continuously supply current to the table lamp.

"It is worthy of being the earliest Royal Academy of Sciences in the world, this strength, tsk!" Xu Mingwu was sincerely admired.

Xu Mingwu sat down, only to find out that he was sitting on a sofa, or a sofa with springs, which was very comfortable!

There were several stacks of newspapers on the coffee table in front of the sofa, Xu Mingwu was bored and turned over to look through them, and he actually saw the interview report on himself at a glance.......

"This report is well written, and I will have to pay the newspaper more in the future!"

Xu Mingwu smiled and continued to browse through the major titles of other editions.

"The first-class sail battleship "Yongle" was launched in Ningbo Mansion yesterday, and this ship became the world's largest sail battleship"

"The Fifth Expedition of the Tianwu Dynasty to the West Will Be Launched in October to Strengthen Trade with Western Countries"

"The Situation in Armerica: The Great Eastern Kingdom and Spain Go to War, and the Puppet Emperor Hong Chengchou Appoints the Puppet King Wu Sangui as the Commander to Fight for the Mexican Trade City"

.......

", Hong Chengchou and Wu Sangui are not dead yet? Running to the Americas tossed? ”

Xu Mingwu took a closer look at this report, but unfortunately it was still last year's news, and it is estimated that the battle has already ended, and he doesn't know what the strength of the so-called Great Eastern Kingdom is.

Xu Mingwu was fascinated, the door rang, and someone opened the door and came in.

He snapped, closed the newspaper, and stared up at the door.

I saw a woman in her thirties walking slowly, her appearance was elegant, her face was plump and round, her apricot eyes were slightly narrowed, and her demeanor exuded grace.

Well, and a good figure.

Xu Mingwu didn't know whether this was the dean Kunxing's eldest princess or her secretary, so he didn't dare to take the initiative to come forward and salute, but just stood up and straightened up to show respect.

However, the big beauty seemed to ignore Xu Mingwu's existence, casually pulled her shoulder-length hair, walked straight to the table, sat down and yawned, and did not speak.

Well? What the?

Xu Mingwu was puzzled, and decided to brake quietly and sit back to see what happened, so he carefully sat back on the sofa and waited patiently.

However, after sitting for a while, the strange beauty got up and picked up a small kettle and began to water the bonsai on the writing desk.

After watering, she went to the fish tank by the window and sprinkled bait to feed the fish......

No....... What the hell is going on?

Xu Mingwu looked confused, but he still didn't dare to say anything, in case the other party was really Her Royal Highness the eldest princess, and he spared her Yaxing, it would not be a joke, and he still expected the eldest princess to introduce his wife as a matchmaker, he must grasp it well, and he must not leave a bad impression!

He continued to meditate, staring at the great beauty.

After feeding the fish, the big beauty stood in front of the floor-to-ceiling window, facing the bright sunshine outside, and began to sing and hum Kunqu opera......

Xu Mingwu was stunned, a little dumbfounded, what's going on? What kind of routine is this?

But then again, the big beauty's voice is very good, her singing is not bad, she is very professional, Xu Mingwu listened patiently, hoping to experience her thoughts in the play.......

However, he didn't appreciate the essence of it after listening to it, but was dizzy and didn't know what was going on.

The big beauty was full of expression, the lotus step moved lightly, and she was just about to change her body to continue a song, and moved to the sofa, and was instantly stunned on the spot.

She coughed lightly, instantly returned to normal, and said with a straight face, "Who are you?" When did you come in? ”

Xu Mingwu was stunned for a moment, as if asking: Who am I? Where am I? What am I going to do?

The big beauty frowned, lowered her face and said, "I'm asking you, who are you?" ”

As she spoke, she walked slowly to the table, slowly opened the drawer, and pulled out a black rotating pistol......

Xu Mingwu immediately woke up and hurriedly explained: "Don't get me wrong, my name is Xu Mingwu, and I was called by the dean!" ”

"You are Xu Mingwu?"

The big beauty did not relax her vigilance, took out a pair of glasses from the sachet she carried, put them on her face, looked at Xu Mingwu seriously, and saw that he was nervous and had no murder weapon, so she put the rotating pistol back in the drawer.

The big beauty smiled slightly, with a slight hint of shyness, and said, "I am the president of the Royal Academy of Sciences, let the virtuous nephew smile." ”
