The noon sun spilled into the white marble bricks of the palace from the window, which was a side hall with luxurious decoration, with gold embroidered screens, bookcases carved from rosewood, and even the burning brazier in the corner of the wall were gilded lacquer basins, which were enough to reflect the noble status of the palace owner.

In the middle of this side hall, a young man in golden civilian clothes was lying on the table, a pair of Danfeng eyes stared intently at the notebook on the table, intently correcting, exuding a mature and confident atmosphere from his body, which was very similar to the steady overlord aura on Li Er's body.

"Yokohama mined 36,000 taels of silver in December, and 64,900 taels of silver in Oban...... well, yes, yes, the silver shipped from Wakoku Island has increased by one from last month."

"General Li Ji led the expeditionary force to continue to advance, and the fourth prince Li Ke also put down all the Central Asian regions ......"

"Ha......" Li Chengqian stretched his waist, yawned, and said to himself: "It's all good news, with Li Ji, a general, guarding Tibet and Central Asia, the fourth brother doesn't have to worry about those remnants of the remaining brave soldiers having plans." ”

Li Chengqian twisted his neck and reviewed the music all morning, even if he was full of energy, this continuous work for several hours still made him feel a little tired, stretched out his hand, Li Chengqian just wanted to ask the ladies to serve tea, the door was suddenly pushed open, and a eunuch hurriedly said with a sharp voice: "His Royal Highness the Prince, His Royal Highness the King of Jin and Princess Jinyang came to visit, and the people have already arrived outside the door......

"Oh?" Before Li Chengqian could speak, two immature voices sounded outside the gate.

"Brother Child, hurry up, this meal is about to get cold."

"Son. Don't run so fast. Be careful of falling. ”

No one has seen it. The sound came first, but when he heard these two voices, Li Chengqian's originally tired face suddenly became cheerful, and a smile appeared on his mouth.

Sure enough, two figures came in from outside the gate, a handsome young man wearing a white velvet jacket, and the other a girl in a fiery red velvet cloak.

"Big brother~" The girl who broke into the door saw Li Chengqian sitting in front of the table, and immediately pounced on her very excitedly. Li Chengqian also hugged her. I saw that this girl looked quite young, only a few years old, but her face was born with bright eyes and bright teeth, smart and smart, she was the last daughter of Li Er and Empress Changsun: Li Mingda, the little son of Princess Jinyang.

"My son's health is not good, and Daoist Sun said that you should recuperate in the palace, why did you suddenly come to visit your eldest brother today?" Li Chengqian asked with a smile at the girl in his arms.

The little girl was not afraid of people at all, and muttered: "Yesterday was the New Year, and I stayed with Brother Zhinu in the Queen Mother's Mansion for a night, and today I came directly from the Queen Mother's Mansion." The father went to inspect the coast, leaving the eldest brother to supervise the country. The queen mother guessed that you must not have eaten yet, so she asked me and Brother Slave to bring you lunch. After saying that, he snorted at the white-furred young man behind him.

Li Zhi respectfully made an eldest brother salute, and then said slowly: "Back to the eldest brother, as the son said, we brought lunch to the eldest brother on the order of the queen mother. Then he clapped his hands, and three eunuchs with wooden cages came in through the door, and I could see the rising heat on the wooden cages.

Li Chengqian nodded with satisfaction and said with a smile: "Those who know me, the queen mother, it just so happens that she is also very hungry in her lonely belly, and it is also a great pleasure to taste the delicious food in the queen mother's house. ”

When the son heard this, he chuckled, "Brother Zhinu and I have already eaten at the queen's house, and today the son ate a big bowl of rice balls, and the queen mother praised the son." ”

Seeing that the lovely people in front of him were so lively and lovely, Li Chengqian also laughed from the bottom of his heart, saying that the royal family has been affectionate since ancient times, but in his own opinion, his family is completely different from the royal family full of crime and murder written in the history books, the royal family of the Li family, there is no intrigue, no conspiracy and calculation, everyone performs their duties, everyone shares weal and woe, supports each other, and every time I see this kind of family warm scene, I will feel full of happiness from the bottom of my heart.

"By the way, eldest brother, when passing by the second brother's mansion, the second brother's housekeeper told me and my son, the second brother rushed to the academy early this morning, what made the second brother so in such a hurry just after the New Year?" Li Zhi asked Li Chengqian with some curiosity.

Hearing Li Zhi's question, the corners of Li Chengqian's mouth suddenly showed a smile and said: "According to the research topic of the second brother that Gu knows, I'm afraid that there is a new invention in my Datang that is about to be born............

"Only new inventions can change the process of science and technology, and only new inventions can promote the improvement of the living standards of the people of Datang." Li Tai told the onlookers about the importance of invention with a shy belly, and behind him, a basket hung under a huge cloth ball, lying quietly, and more than a dozen Mr. Mo Jia, dressed in academy clothes, were doing the final examination.

In the days of the New Year, the food of big fish and meat has made Li Tai gain a lot of weight, but this does not affect his enthusiasm, because today is the day of the new invention test developed by him and several old gentlemen of the Mo family.

"Blue Sparrow." A shout suddenly came from the distance, Li Tai looked up, and saw a carriage parked on the edge of the square, a little abrupt in the empty playground, Li Tai saw at a glance that the middle-aged man who walked down from the carriage was his mentor, Mr. Xu Yang, Guiguzi.

"Hurry up, it's better to come early than to come by coincidence, just in time for the hot air balloon to fly into the sky, let you see how people can fly into the sky." Xu Yang ran down from the carriage, and behind him, there were five children, big and small, except for the youngest Wanshu, who was still at home, and the five children were all chattering around him.

"Daddy, what is a hot air balloon?"

"Daddy, aren't you going to visit Daoist Sun at the academy? How did you get to this square? ”

"Daddy, how can people fly to the sky......"

Several children asked endlessly, Xu Yang coughed, and the eldest Nian Qing took his younger brothers and sisters to silence, waiting for his father to speak.

"Daddy brought you here today, mainly to see this hot air balloon, this is an important witness moment in the history of my Datang aerospace, Daddy doesn't want you to miss every moment of our Datang strength, so I took you to see, after the hot air balloon takes off, what questions do you have, and then ask Daddy, Daddy will answer you one by one, do you understand?" …… (To be continued......)
