After being demoted, my 300,000-strong army trampled the imperial city!

The mathematics curriculum at the Northern Xinjiang Academy uses Arabic numerals, which Chen Futu named Xia numerals, as they are extremely convenient to use.

Furthermore, the use of pinyin for literacy astonished Liu Longyue.

After most of the day, Liu Longyue felt that her understanding had been completely overturned.

The knowledge imparted by the Northern Frontier Academy is far from the Confucian classics of the outside world, nor does it copy the classics of great Confucian scholars. In particular, the study of things gave Liu Longyue a completely new understanding of the power of the Northern Frontier.

She suddenly realized that she knew nothing about the Prince of Zhenbei. This man's talent was different from any other era, and even out of step with this world. It was an unprecedented feeling, as if her soul had been baptized, or as if knowledge from beyond the heavens had come, violently impacting her worldview.

Even Chen Yuling stopped talking.

She found an opportunity to ask quietly, "Are you still my brother? How come I didn't know you knew so much?"

In her mind, her brother was a lazy playboy who spent his days lying around doing nothing. After their father passed away, her brother seemed to have become a different person. He was not only exceptionally talented, but also had a variety of ingenious methods. His peerless strategists and unparalleled generals appeared out of nowhere.

She would never believe it if you told her that her father had left behind a team.

Chen Futu affectionately patted her head and whispered, "No matter what your brother becomes, you will always be my sister, and I will protect you for the rest of my life."

"Hehe, I believe in my brother~"

Chen Yuling nodded arrogantly, hands on her hips.

Liu Longyue watched the scene of deep affection between the brother and sister and fell silent once again.

She also had an older brother, but unfortunately, that brother always used her, even going so far as to push her out as cannon fodder. If it weren't for her deep foundation in the Northern Martial Arts, she would probably have died long ago.

"Your Highness, may I have a word with you?"

The resistance and hostility on Liu Longyue's face had diminished considerably at some point.

Chen Yuling immediately grabbed Chen Futu and said, "Brother, I'm hungry, let's go eat."

"it is good."

Chen Futu gave Liu Longyue a deep look, then led the two to the canteen deep inside the academy.

"The young master is actually taking care of the students' lives as well." Liu Longyue asked suspiciously.

The students here eat too well; they even have meat, and the dishes are not much different from the delicacies in the Prince's mansion.

Liu Longyue said smugly, "You don't know yet, do you? This is a cooking technique taught to me by my brother."

"Does the young master know how to cook?"

There's an old saying that a gentleman keeps away from the kitchen, let alone the dignified heir of the Prince of Zhenbei.

Chen Futu explained, "Food is the most important thing for people. Only when they are full can they have the energy to do other things. Simple ingredients can be made delicious with careful processing, just like governing a city. You need to find the right method."

Liu Longyue paused, then asked, "Even though Beiwu is bitterly cold, it has its merits."

"That's natural."

How could Chen Futu tell Liu Longyue that the black soil of Beiwu was very fertile?

In the original world, the area where Beiwu was located could be considered the granary of the world, but unfortunately they didn't know how to develop and utilize it.

Upon seeing Chen Futu, the canteen staff immediately busied themselves preparing and serving him food.

Liu Longyue asked, "Don't the students spend money on these meals?"

The attendant said, "The young master is kind-hearted. He said that the students are growing and need to be nourished. The students who graduate from here will be entrusted with important responsibilities in the future. If we can reduce the worries of poor families, that would be wonderful."

These few words deeply shocked Liu Longyue.

How many emperors in the world would care about such trivial matters? Even in a powerful dynasty like the Great Qian, the students of the Imperial Academy still earned their own living.

Chen Futu saw through her thoughts and smiled slightly, neither agreeing nor disagreeing.

With the help of the Northern Xinjiang Commercial Bureau in doing business, and the Development Zone being a golden goose, he's actually not short of money.

Liu Longyue asked, "Since the young master left the capital, why has he spared no effort in launching wars? Is it for revenge?"

"Why would the princess ask such a question?" Chen Futu was in a relatively good mood, so his attitude was somewhat better.

“It is said that every battle must yield something. When the Crown Prince returned, he plundered a lot of resources along the way, but it was just a drop in the ocean for the entire Northern Frontier. Your legions can stay peacefully in the Northern Frontier. You can simply bypass the Northern Mountains and return. There is no need for war.” Liu Longyue’s question was very sharp.

Chen Yuling, standing to the side, scratched her head, racking her brains, but couldn't find an answer.

Chen Futu shook his water cup and replied, "If we cannot gain prestige and establish an invincible reputation, where will the people get the courage to risk displacement and join a power with no future?"

Upon hearing this, Liu Longyue was speechless.

Chen Yuling exclaimed in surprise: "That's why Brother spared no effort in launching the war, just to let the world see the strength of the Northern Frontier and increase their confidence."

"To do a good job, one must first have the right tools. What the northern border can rely on is the hearts of the people. The people trust us, and the displaced people are willing to migrate. This will lay the foundation for filling the northern border's population. Only then can I lead the northern border to withstand pressure from all sides and remain invincible in the future."

From the moment Chen Futu left the capital, every step he took and every action he took was for the future of the northern frontier.

As it turns out, the reputation gained through continuous warfare has been effective, and the northern frontier is now thriving, all of which is built on a strong military foundation.

"As expected of the Crown Prince." Liu Longyue gave a wry smile, lowered her head, and seemed lost in thought.

She was somewhat absent-minded during the meal, and it took Chen Yuling several calls before she came back to her senses when she was leaving.

"Hey, what are you thinking about? You're not thinking about something bad, are you?!"

Chen Yuling had a look on her face that said, "You see right through me."

Liu Longyue thought for a moment, then took out an exquisite hairpin from her sleeve. "Here you go."

"Unsolicited kindness is either a treacherous act or a theft; I don't want it."

Chen Yuling pouted, refusing to accept the gesture.

Seeing Liu Longyue's embarrassed expression, Chen Futu said, "Take it. She is the dignified Princess of Beiwu, and the nominal Crown Prince's wife. She can afford to give such a small gift."

"Ok."

Chen Yuling then took the hairpin and shouted, "Don't think you can buy me off with small favors. Let me tell you, I support General Qin."

"I see."

Liu Longyue smiled, her beauty breathtaking.

Even Chen Futu's dislike for her diminished considerably with a smile.

On the carriage ride back, Liu Longyue smiled even more, her gaze frequently falling on Chen Futu, her beauty and charm captivating as she looked at him.

Chen Futu felt uncomfortable under her gaze and frowned, saying, "You can speak your mind directly; there's no need to hide anything."

"Is it true that no matter how barren a place is, there is always a way out?"

"of course."

"Where is Beiwu?"

Liu Longyue's elegant white fox face was filled with a strong thirst for knowledge.

She hadn't been in the Northern Frontier for long, but she had heard that Chen Futu had vigorously developed civil affairs and distributed many rare crops. If possible, she wanted to learn from his experience to make life in the Northern Frontier better.

But will Chen Futu tell her?
