When Zhu Yuanzhang heard this, he pondered for a moment and then understood what his eldest grandson was thinking.

"It seems that my eldest grandson is already clear about his identity." Zhu Yuanzhang nodded and said with a smile.

"Liu He, come here."

"I am here."

"Arrange the documents for the post station for Da Sun, and prepare a few blank documents for Da Sun to fill out himself."

Zhu Yuanzhang ordered with a smile.

"I obey your order."

Liu He lowered his head and said, then went to make arrangements.

This operation was the idea that Zhu Yuanzhang came up with from the "Empty Seal Case".

The original empty seal case involved a large number of blank documents with seals.

Zhu Yuanzhang understood that his eldest grandson's traveling merchants to the border areas of the Ming Dynasty would certainly have a great demand for post stations.

After hesitating for a moment, he called Liu He back.

"Prepare a post station seal and documents for Da Sun, and let him arrange it himself."

"I obey your order."

Outside the Meridian Gate, Song Zhong paced back and forth, waiting anxiously.

Even though he was the Jinyiwei pacification envoy, he was not allowed to enter the palace without an imperial order and was not on duty that day.

The Jinyiwei on duty had already drawn up the list two days in advance, submitted it for review, and then entered with their badges.

"Why did it take so long? These little bastards are so unreliable." Song Zhong kept looking towards the gate.

The tightly closed door still showed no movement.

"Damn it, if Master Zhu gets impatient waiting, I will definitely train these little bastards well when I get back."

Song Zhong said bitterly that when he passed the message, he had already asked the Jinyiwei on duty to do their best.

Finally, there was a creaking sound from the Meridian Gate, and the sound of the door opening was heard.

Hearing the voice, Song Zhong walked over without hesitation. When he saw the figure coming out, he wanted to scold the person first.

"you……"

Just as he opened his mouth, Song Zhong's voice stopped abruptly, and the figure that came out was not wearing the brocade clothes of the Jinyiwei, but the clothes of the eunuchs of the Silijian.

Looking at that face again, it is clearly the eunuch Liu He, who is in charge of the Imperial Household Department, also known as Eunuch Liu.

The Embroidered Uniform Guard is in charge of external affairs, and the Imperial Household Department is in charge of internal affairs.

At present, the relationship between the Imperial Household Department and the Embroidered Uniform Guard is relatively harmonious.

It completely describes the confrontation between the Jinyiwei and the eunuchs in the middle and late Ming Dynasty.

Everyone is wholeheartedly serving the imperial power. The most important thing is that the reputations of the Jinyiwei and Silijian are not much different.

They were all despised by the civil and military officials and the noble groups in the court.

As the seal holder of the Imperial Household Department, Liu He's status was equal to that of Jiang Lin, the commander-in-chief of the Embroidered Uniform Guard.

This is several levels higher than Song Zhong, the pacification envoy.

"Eunuch Liu, how can you come here in person for such a small matter?" Song Zhong said with a smile, the angry look on his face completely gone.

Liu He snorted coldly and said, "No matter how small the matter of His Royal Highness Chang Sun is, it is a huge matter for us. You have no rules at all."

Upon hearing this, Song Zhong quickly said, "You are right, eunuch."

Theoretically speaking, Song Zhong was not afraid of Liu He. After all, they were not in the same system. Even if he wanted to punish him, only Jiang Li could come.

Everyone was doing similar work, and Jiang Li didn't want to please Liu He, so he didn't have so many concerns.

If any small matter is brought to the attention of His Majesty, no one will suffer any consequences.

And the current matter mainly involves His Royal Highness Changsun. If Eunuch Liu makes a sound in front of His Majesty, Song Zhong's life will be in danger.

Liu He didn't want to argue with Song Zhong, but carefully took a wooden box from the eunuch behind him and handed it to Song Zhong, while instructing:

"Here are ten blank documents and the seal of the post station. I will give them to His Royal Highness Chang Sun later."

Song Zhong was stunned when he heard this.

Blank document? Post station seal?

It seemed like Master Zhu Ying just wanted a document from the post station, but not only did he send ten copies, he even sent a seal?

This is a post station. If the prince consort interferes, he will be executed.

Song Zhong's hands trembled slightly. He now fully felt the position of Zhu Ying in His Majesty's mind.

She hasn't entered the palace yet, and her identity hasn't been completely confirmed.

At this moment, Song Zhong seemed to see the future emperor of the Ming Empire in his mind.

"What are you still standing there for? Send it to His Royal Highness Chang Sun immediately."

Liu He saw Song Zhong suddenly freeze and scolded him.

"Yes, yes, yes."

Song Zhong took the brocade box with both hands, not daring to delay. He greeted Eunuch Liu and hurried towards the Jinyiwei Yamen.

While running, he held the brocade box in both hands, not daring to slack off for the moment.

In the Jinyiwei Yamen, Zhu Ying sat quietly, calm and without the slightest impatience.

During his free time, he was thinking about how to better position himself to compete for the throne.

"Lan Yu is still in Handong now. The old man issued an urgent decree, and it is estimated that he will be back in about ten days."

"The meeting with Lan Yu is crucial. It would be awkward if he doesn't recognize me as his nephew."

Zhu Ying secretly thought to himself that he had previously looked down on Lan Yu, thinking that he was just a reckless man.

However, now that we know the old man's general arrangements, we have to make certain changes.

"The old man must have wanted to eliminate Lan Yu earlier. Now that I've appeared, it's Lan Yu's only chance to survive. But Lan Yu is too arrogant and domineering. He doesn't understand these rules at all."

"It's really difficult to act completely based on your own preferences."

"Besides, the old man probably doesn't simply look at the relationship between me and Lan Yu. In a more meaningful sense, he wants me to completely suppress Lan Yu instead of being controlled by him."

"Only in this way can Lan Yu become my assistant and he can survive."

After thinking it through, Zhu Ying felt a little depressed.

Although he had never had contact with Lan Yu, he had collected a lot of information about Lan Yu.

This guy even dared to talk back to the old man at the banquet in the palace.

It's really difficult.

After thinking it over, there are only two things that can shock Lan Yu.

One is one’s own identity.

The second is to suppress it by relying on personal force.

In ancient times, it was easy to create a cult of personality if one had overwhelming military power. Coupled with this special relationship, the possibility of suppressing Lan Yu was generally very high.

While he was thinking, the door was cautiously pushed open.

"Mr. Zhu, I'm sorry to have kept you waiting."

Song Zhong walked in holding the brocade box in both hands, and the Jinyiwei outside the door closed it gently.

Zhu Ying stood up and said with a smile: "It's only been a short while, just a cup of tea, thank you for troubling Song Zhenfu."

"Mr. Zhu, please don't be polite to Song."

Song Zhong replied, then walked over and presented the brocade box with both hands.

"What is this?" Zhu Ying asked as he took it.

"Master Zhu, here is the seal of the post station and ten blank documents." Song Zhong said, but he did not dare to say more, even though His Majesty and Master Zhu Ying knew about it.

But even if there was a layer of window paper between them, he, a small pacification envoy, was not qualified to break it.

Zhu Ying nodded, a hint of surprise flashed in his eyes, but he didn't say much.

Just open the brocade box and take a look.

Inside the box, there was a pile of blank documents on the right and a seal on the left.

Zhu Ying picked up the seal with some curiosity and looked at the bottom.

What is engraved on it is: Vehicle Frame Department of the Ministry of War.

My goodness, this is not just about the post station.

The Chariot Department of the Ministry of War was also responsible for the mobilization of military horses and the use of carriages.

In other words, with this seal, Zhu Ying's rights are not limited to the post station.

Zhu Ying remained calm, put the seal into the brocade box, and said to Song Zhong with a smile, "Thank you for your help, Song Zhenfu."

Song Zhong bowed slightly and said, "It is my honor to serve Mr. Zhu."

Zhu Ying nodded gently and said, "I will remember the help of Governor Song. Please rest assured, Governor Song, I may come to bother Governor Song again in the future."

Hearing this, Song Zhong's eyes flashed with surprise, and he hurriedly said, "If Mr. Zhu needs anything from me, just let me know. I will do my best to serve you."

"Okay, then I won't bother you any more and will take my leave first." Zhu Ying was not surprised to hear this. After nodding, he prepared to turn around and leave.

"Mr. Zhu, I'll take you there." Song Zhong hurriedly stepped forward, bowed slightly, and opened the door for Zhu Ying.

Outside the door, in addition to the Jinyiwei guarding the door, there was another Jinyiwei holding a file and waiting.

Obviously there was something going on and he wanted Song Zhong to handle it.

However, he was stopped by the Jinyiwei guarding the door.

Zhu Ying took a look and said casually, "I won't bother Governor Song any more. Governor Song should handle his official duties first. Official duties are more important."

"Mr. Zhu, take care. Boy, why don't you go and see him off." Song Zhong first said to Zhu Ying with a smile, and then said to the Jinyiwei who had passed the message to Zhu Ying and was guarding outside the door.

"As you command."

The Jinyiwei said this, and then respectfully followed Zhu Ying away.

After Song Zhong lost sight of Zhu Ying, he turned around and walked back into the house. After he sat down at the main seat, he said to the Jinyiwei who came to report:

"What is it? Tell me."

The Jinyiwei quickly handed over the file and said, "Sir, this is the file of Huang Zicheng, the editor of Hanlin."

"Just half an hour ago, we caught two people sneaking around, and they seemed to want to find out what happened after His Majesty left the palace."

"The brothers captured them and interrogated them strictly. They confessed that it was Huang Zicheng who was behind it."

Upon hearing this, Song Zhong took Huang Zicheng's file, looked at it carefully, and confirmed that he was the same Huang Zicheng he knew.

This is Huang Zicheng, the companion reader of the Eastern Palace. As the confidant of the Emperor's grandson Zhu Yunwen, he has been very proud and elated recently, especially after Zhu Yunwen was designated as the Crown Prince by His Majesty.

The Jinyiwei has detailed records about Huang Zicheng.

Song Zhong frowned. Since this matter involved the Crown Prince, it would be difficult to handle.

After opening the file and flipping through it, he saw that Huang Zicheng had been frequenting brothels, Qinhuai Flower Boats, and the Jiaofangsi almost every day.

"This guy is already 40 years old, but he doesn't know how to take care of his body."

Song Zhong said speechlessly.

"Sir, look at this..." The Jinyiwei asked Song Zhong about the arrangements.

Song Zhong pondered for a moment. As of now, His Royal Highness Chang Sun and His Royal Highness Tai Sun were obviously secret enemies.

Being able to strike a blow to the Crown Prince Zhu Yunwen is equivalent to helping His Royal Highness the Chang Sun.

But if he takes action directly, he may not be qualified.

"Seal the files. The two people in the prison will be detained for now. We will deal with them after Commander Jiang returns. Don't worry about this matter for now."

"As you command."

At this moment, in a courtyard in the capital.

Huang Zicheng paced back and forth anxiously in the yard. Under the entrustment of His Royal Highness the Crown Prince, he could only bite the bullet and arrange for his servants to investigate.

An hour had passed and there was still no news, which made Huang Zicheng feel panicked.

Secretly inquiring about Your Majesty's whereabouts is a serious crime. If it is really discovered and severely punished, it would be tantamount to hiding one's evil intentions and the same crime as treason.

But what could Huang Zicheng do? His Royal Highness the Crown Prince had already done that, and he had no way of refusing.

He didn't even dare to ask his colleagues and friends for help.

Things like this can only be done secretly in private.

"I brought them all from my hometown. I'm sure they won't betray me even if they're caught."

Huang Zicheng comforted himself in his heart.

The two servants he sent out were from the same hometown as him and had always been regarded as Huang Zicheng's confidants.

Just as this thought came to my mind, I saw the old butler coming over in a hurry.

That panicked look shocked Huang Zicheng.

"Master, something terrible has happened. They have been captured by the Jinyiwei."
