On the eighth day of the sixth month of the fourth year of Jianwen, King of Yan Zhu Di raised hundreds of thousands of troops to station in Longtan, which was only 60 miles away from the capital. The four-year Jingnan Campaign was about to come to an end.

On June 11, the Yan army camp.

Qin Feng was wearing a sweatshirt, rolled up his trouser legs, and stepped on straw sandals. He was held in the tent of the King of Yan by more than a dozen bright spears.

"Report to your Highness, this kid sneaked into the camp and was caught by the mark."

Zhu Di in the tent and his subordinates, wearing armor or Confucian robe, immediately looked at each other like swords.

Zhu Di's thigh was a huge, thick thigh, so he had to hold it firmly.

"Your Highness of the King of Yan..."

In order to show his sincerity, Qin Feng hurriedly stepped forward to greet him.

It's a pity.

Before he could take his lifted foot, he felt something sharp approaching his waist and approaching it. He was only a small step before he could stab it into his waist.

"Don't move."

Qin Feng slapped his forehead and raised his hand, quickly retracting the step he had not taken yet.

Damn, how could he forget his current situation?

Can the Yan King's camp be able to walk around as he is a person of unknown origin?

If this is stabbed as an assassination person, the designated medicine stone will be left without a doctor.

He didn't want to die again just a few days after traveling through time.

"Don't move, don't move... Dear brothers, you have no eyes on the sword, you must hold it tightly. If Qin's blood splatters on the spot, Yan's army will not be able to enter Yingtian Mansion."

In history, Zhu Di was Yingtian Mansion two days later. Even if he didn't come, it would not prevent Zhu Di from becoming Emperor Yongle.

He said this to explain his purpose here, and to show his importance so that those soldiers can be more cautious.

Unexpectedly.

As soon as he finished speaking, the tall and arrogant young general stepped in front of him in three or two steps, pulled out a sharp blade and rode it around his neck with a whoosh.

"Say, who sent you here, dares to have a lie and kill you."

If there is a sharp blade in front and a spear in the back, it will be poked into a bloody hole if you accidentally.

How could this situation be more dangerous than just now?

Qin Feng raised his chest and sucked his abdomen, but he didn't dare to move.

"Who sent it? This young general treated Qin as a meticulous one? Oh, the young general really misunderstood. His Highness, King Yan, is extremely handsome, and Qin has long wanted to surrender to His Highness.

The Yan army stationed in Longtan but did not send troops for a long time. It was a good opportunity to enter Yingtian Mansion? It happened that Qin had a good plan."

There is no doubt that Zhu Di's ambition to enter Yingtian Mansion is never a life-and-death under the throne.

I finally found a good plan to enter Yingtian Mansion, so I must listen to it.

"How did you know that I want to enter Yingtian Mansion? Besides, there are so many capable people under my command. Even if I really want to enter Yingtian Mansion, you don't need to offer your advice, right?" Zhu Di spoke heavily.

There are many capable people in the Yan army, which is undeniable. Otherwise, it would be impossible to use the power of a mere vassal king to defeat the huge court without any resistance.

But these promiscuous people can only attack forcefully in front of Yingtian Mansion and cannot do anything smart.

Zhu Di, a vassal king, would he still have a reputation if he attacked Yingtian Mansion?

Qin Feng avoided the sharp blade on his neck a little, and did not dare to be too large. He said, "Your Highness, can you bother this young general to take this thing first? It's so scary."

No matter what, since Zhu Di answered his question, he was just going to listen to his good plan. Now he is just a meat on the chopping board, so he wouldn't have to treat him with swords when he listened to his good plan.

Under possible conditions, he certainly wants to fight for the most favorable situation for himself.

"Gao Xu!"

After a while, Zhu Di shouted and sent the soldiers behind Qin Feng with a spear in his hand.

Oh, isn’t this Zhu Gaoxu who was roasted by his nephew?

Behind the sharp blade, Qin Feng followed Zhu Gaoxu with a favor.

"So it's the second prince, I'm so respectful."

No matter what, he is still a prince for more than 20 years. Even if he doesn't consider hugging his thighs, he cannot easily offend him.

Without waiting for Zhu Gaoxu's response, Qin Feng took a few steps forward and saluted Zhu Di.

"Boy Qin Feng, pay homage to His Highness, King Yan."

Although there are no swords and swords to force each other, the crisis has not been resolved.

After seeing Li, Qin Feng stopped taking Qiao, and asked, "My grandfather next door had participated in the construction of Yingtian Mansion when he was young. He heard that he was invited away by Yan's army this morning. He guessed that Your Highness wanted to find a passage from the craftsmen who participated in the construction of Yingtian Mansion to enter the city without knowing it, so as to cooperate with the general guarding the city inside and outside?"

Historically, Li Jinglong opened the Jinchuan Gate and let Zhu Di enter the city, and Zhu Di must have been connected with him in advance.

Otherwise, it would be impossible that Zhu Di had just arrived at Jinchuan Gate, and Li Jinglong opened the city gate without even hesitation.

Qin Feng said something, Zhu Di's eyes were a little sharp, and the Yan army members in the tent also held their breath and stared at him.

Even so, Qin Feng has temporarily taken over the leadership.

Under the pressure of many pairs of sensational eyes, he said: "Most of the craftsmen who could come into the city when they were building Yingtian Mansion were experienced old craftsmen. They have basically passed away for nearly forty years. As for those who are alive now, they were just small workers, doing some mixing materials and moving bricks, so how could they know how to get into the city?"

This is a situation analyzed based on historical books and current background, and the difference is not much.

Zhu Di grabbed the chair handle with his right hand and rubbed it back and forth, and asked, "So, do you have a way to enter the city?"

What you want is Zhu Di's words.

Qin Feng suddenly showed joy and replied, "Yes, I know that there is not much rainfall in the past few days, so you can go in here."

In his previous life, his parents were archaeologists, and various historical records and materials in his family were piled up. He happened to be interested in these things. A few years ago, he studied the annual precipitation in Yingtianfu during the Ming Dynasty and the drainage pipelines in Yingtianfu.

Unexpectedly, a hobby that I had nothing to do came in handy.

Zhu Di looked at Qin Feng for a while, but there was no joy on his face. He raised his hand and said, "Let me mark the location of this drainage pipe first."

If Qin Feng wants to gain Zhu Di's trust, he has to look at the drainage pipe signs.

Then, he took three or two steps to the map placed beside Zhu Di, and marked the well-known drainage pipe that had long been conceived.

His other abilities may not be outstanding enough, but his memory is definitely excellent.

The route was marked out, and Zhu Di and a group of subordinates were stroking step by step on the map.

Among the group of people was a child of 17 or 8 years old, and they were also looking and asking as they followed Zhu Di's gesture.

At this age, the only one who can follow Zhu Di and asks about things is Zhu Zhanji.

Zhu Di looked down on Zhu Gaochi's son, but he was very optimistic about Zhu Zhanji's grandson.

Zhu Zhanji did not make a move rashly, and Qin Feng did not make a move to say hello to him.

If you want to get to know Zhu Zhanji, there will be opportunities in the future, so there is no need to rush to this moment.

Zhu Di has been in the vassal state for a long time when he went out, but he has lived in Beijing for many years. This drainage ditch was founded when the city was built, and it was not built in recent years.

Zhu Di can still tell how true or false it is.

After a long time of stroke, Zhu Di sat back to his previous position and asked, "I wonder where the little brother knows the drainage route?"

The change in title is the first step for Qin Feng to gain Zhu Di's trust.
