Mother, I have returned to the throne.

Sitting at the desk, Song Yuan frowned and pondered, then finally picked up the feather pen and began to write down what was in his mind one by one.

In Song Yuan's view, so-called agriculture is nothing more than basic people's livelihood.

At most, it can only fill your stomach!

Now that I have occupied a vast territory, if I just want to ensure that everyone has enough food and clothing, this condition alone may not be enough.

Everyone must also be able to make money!

But if you rely on agriculture to make money, it is basically just a fantasy.

Judging from Song Yuan’s experience in two lifetimes, making money must ultimately be based on industry!

When it comes to industry, the most indispensable thing is various large and small mineral deposits!

From small things like coal mines providing energy to large things like various precious metals, they are all indispensable in the industrial production process!

The border area is vast and sparsely populated. According to Song Yuan’s experience, there are probably a lot of minerals hidden underneath!

Next, finding these minerals should be the top priority!

As long as you can discover one of them, you will have a way to boost the overall economy.

If an industrial chain can be formed by then, Song Yuan will be able to build the border area under his control into a business empire that far exceeds the behemoth Qin!

However, you have to eat one bite at a time and walk one step at a time.

The most urgent task now is to suppress the barbarians first!

Things still need to be prioritized, and subsequent plans need to be carried out step by step.

In your current situation, you don't have the conditions to implement it, and you can only imagine it in your mind.

Ye Xuan was always by Song Yuan's side, and he would grind while Song Yuan was writing.

From time to time, she would move forward and take a look at what Song Yuan had written. As the number of words on the paper increased, Ye Xuan felt even more confused!

Among the words written by Song Yuan, some of them were understandable, but for the most part, he had never even heard of them!

However, even if she could only understand a few of them, Ye Xuan was still completely surprised!

The principles of governing the world involved in this made Ye Xuan's eyes light up!

He has lived in the palace since he was a child, so he is quite down-to-earth. From the perspective of a commoner, he can better perceive the mystery of it!

What Ye Xuan saw in the middle made her realize in an instant that Song Yuan was not only brave and good at fighting on the battlefield, but also possessed the talent of a general!

Even in real life, he is definitely a genius in governing the world!

He used to be very low-key, but now he finally has a stage to show his talents. He had been keeping a low profile and had accumulated countless achievements. Perhaps he had already started preparing for this day more than ten years ago?

"Tuk tuk tuk..."

Just as Ye Xuan was surprised, a knock on the door suddenly interrupted their thoughts.

In order to prevent Song Yuan from being disturbed, Ye Xuan hurried forward. The moment she opened the door, a familiar voice came into her ears.

"Sister-in-law, why are you here?"

The one calling out from outside the door at this moment was Situ Jing. Seeing Ye Xuan's disheveled clothes, there was a hint of weirdness in her eyes instantly!

Situ Jing narrowed his eyes and looked into the room through the gap. The mess on the bed made his face suddenly look a little ambiguous!

"Sister-in-law, you didn't..."

"Shh, don't talk, don't disturb him, he's writing something very important now!"

Situ Jing was a little curious and immediately wanted to ask about his experience last night, but before he could finish a sentence, Ye Xuan quickly suppressed her shame and shook her head at Situ Jing!

Seeing Ye Xuan's expression, Situ Jing immediately realized that this matter might be of great significance. He quickly suppressed the teasing thoughts in his heart and spoke seriously.

"I'm here to inform him that Duke Wei is leaving!"

Hearing this, Ye Xuan's pupils suddenly flashed with surprise. It was not until this moment that he finally remembered.

At the banquet last night, Duke Wei said that it was time for him to go back.

After the two left the table, they were all talking sweetly to each other, focusing on the sweetness between the young couple.

Just put this matter behind you!

"You come with me!"

Realizing the seriousness of the matter, Ye Xuan certainly did not dare to delay. She hurriedly pulled Situ Jing to Song Yuan's side and told him the matter about Duke Wei.

Upon hearing this news, Song Yuan was immediately surprised and slapped his head.

"I almost forgot about this!"

After reacting, he pondered for a moment and waved at the two of them.

"Then you two go talk to Duke Wei first, and tell him not to leave yet!"

"I'll take advantage of this time to write a letter to my father, and then ask Duke Wei to help bring it back!"

Faced with such an arrangement, the two nodded pretentiously.

However, as soon as she left the room where Song Yuan was, a gossipy expression immediately appeared on Situ Jing's face.

"Sister-in-law, why did you sneak into Song Yuan's house so early in the morning? Tell me, where were you last night?"

Faced with Situ Jing's teasing, Ye Xuan suddenly felt endless shyness in her heart, but in order not to expose herself, she could only suppress the restlessness in her heart.

"What are you talking about? Can't you see he's writing something important? I'm just helping him grind it!"

"I think there's more to it than that?"

Situ Jing's eyes narrowed immediately, and she lowered her voice and whispered in Ye Xuan's ear.

"If I'm not mistaken, did you sleep with him last night?"

"How can you say such things?"

Situ Jing suddenly panicked, her cheeks flushed, and she denied it in a panic.

"How could it be what you think? Have you forgotten what mother told you last night? Didn't you ask me to ask him? That's why I came here so early in the morning!"

"I happened to see him writing something, so I just came over to help him..."

"Okay, sister-in-law, stop lying to me! I went to your room last night and you weren't there!"

"You...you actually came to find me?"

Situ Jing's face suddenly darkened and she said something shocking. When Ye Xuan heard this, her body trembled and she immediately lowered her head, no longer daring to deny it!

"Okay, sister, stop pretending. I was just lying to you! Who knew you were so easily fooled?"

Situ Jing looked at Ye Xuan with an embarrassed expression and whispered, "Mother has said so much in front of me, how could I not know what you mean?"

"We are all family. In my eyes, wouldn't it be better for you to be my sister?"

"If I were to tell you, you'd be his sooner or later. Why are you hiding something from me? Are you afraid I'd get jealous?"

After staying with Song Yuan for such a long time, even someone as crazy as Situ Jing would have become much smarter!

Asking Song Yuan about pregnancy early in the morning?

With Ye Xuan's thick skin, how could she be so bold?

"Sister, don't think too much. Don't worry, I can't even send you my blessing if you're with him!"

"Tell me quickly, was this bastard too proud last night?"

"Has it been a whole night of tossing and turning facing a beauty like you?"
