Qin Feng thought about how to answer this question before coming.

"My father is a scholar. In addition to the scriptures, he also likes to read some miscellaneous studies. Among them, the construction of urban drainage pipes is among the father's research. In addition to the drainage map of Yingtianfu, there are more than a dozen other places that should be where my father borrowed them to study during his lifetime."

His father liked to read miscellaneous books in this life, and it was not groundless that he liked to read miscellaneous books. In addition to the classics and classics in his family, there were also many miscellaneous books.

This reason is just a matter of time.

Zhu Di then invited Qin Feng to sit down and called someone to take tea.

From the suspected detailed work, Qin Feng finally took the seat of the guest of honor after many dangers.

But this is far from enough.

The merit of offering a plan to sneak into the city is not enough to stand out among the honor generals who licked blood from the edge of the Jingnan period.

What's more, he has an unknown burden.

On the day he came, his unlucky uncle said that he had found the way to the county magistrate of Shangyuan County. As long as he could pay money and help the court pacify Yan, he would be rewarded by the court after he could kill the Yan thieves.

Afterwards, he took the only thirty taels of savings left in the house from his skewed grandfather and rushed into the city.

How his uncle is now unknown, but if his uncle is classified as the Jianwen Remnant Party in the future, his nephew, who has not even been born in the three tribes, will inevitably be implicated.

For the sake of himself and his mother in this life, Qin Feng could only try his best to add more chips to his contributions.

His father fell into the water and died before taking the provincial examination.

Qin Feng took a sip of tea and then opened his mouth again, saying, "But Your Highness, the drainage passage is very narrow. You need to find a petite person to pass through. If you want to contact the city, you must be a person familiar with the route in the middle of the capital. You are not willing to go to the messenger and your Highness to travel."

It is credible to only offer a plan to enter the city. It is questionable that the petite figure and familiar with the capital are just tailor-made for Qin Feng.

Zhu Gaoxu was furious and immediately stepped forward and grabbed Qin Feng's clothes, and said angrily: "Did you do it on purpose, right?"

Is it obvious if it is intentional?

The drainage pipe he recorded was not only one place, but also one was apart from being wider and narrower, which had obvious requirements for the body size of the passer.

In order to ensure that he has earned this contribution, Qin Feng had to bite the bullet and defend himself, saying, "This was not intentional? The Second Prince really misunderstood. The drainage ditch is only five feet long, and it is not easy to pass the size of the Second Prince."

Of course, Zhu Di would not be as anxious as Zhu Gaoxu. All he wanted was someone who could contact him.

Even if Qin Feng deliberately did it to seize the credit, he could accept it.

However, before Zhu Di spoke again, Zhu Gaoxu said whispered: "Father, this kid is too unreliable. He broke into my camp. Maybe it was just to spy on the news of our army. After being arrested, he came out to argue with some drainage pipe."

This is what I said.

If he really did a careful job, how could he know the location of the drainage pipe?

Even if I happen to know, how could I tell Zhu Di such important information?

If there is no guarantee that Zhu Di will send him into the city to connect, wouldn’t this throw out Yingtian Mansion’s weakness?

In fact, since Qin Feng identified the exact location of the ventilation duct, no matter his purpose, it would never be a detailed work by Emperor Jianwen.

Zhu Gaoxu is a typical warrior.

Then, he said impatiently: "Why do you want my son to do so much trouble? Give him 20,000 troops, and his son will be able to lead his troops into the city immediately."

It is not difficult to use Zhu Di's current troops to attack Yingtian Prefecture.

But you, a vassal king, Fengtian Jingnan, was to attack the treacherous and slander for the court. If you lead troops directly to attack the city, it would be either a treason or a treason.

If Zhu Di really did this, before he could become emperor, there would be soldiers who would fight against Yan immediately.

Qin Feng stopped Zhu Gaoxu before Zhu Di and said bitterly: "What are the words of the Second Prince? His Highness of the King of Yan went to the capital to fight against the treacherous and treacherous for the court. Huang Zicheng and Qi Tai's treacherous and treacherous leaders were still recruiting soldiers outside. Yingtian Mansion was not controlled by the treacherous and treacherous, how could His Highness attack the city?"

Qin Feng had to let Zhu Di know that he could not only give him a picture of the drainage pipe alone, but also be able to act as a messenger to help him come to the city to deliver messages.

"Get out if you are not good at it." Zhu Di cursed.

It is true that Zhu Di started to raise an army for the throne, but this statement can never be said openly.

Even if Zhu Di really became emperor, it would have to rely on others to speak for it.

Although Zhu Gaoxu was not convinced, he did not dare to force Zhu Di's pressure.

Only when he left, he threatened Qin Feng very much.

"Boy, if you let me know that you have bad intentions, I will definitely not be able to spare you."

Qin Feng proved himself through Zhu Gaoxu, but he could not offend Zhu Gaoxu all the time.

Under Zhu Gaoxu's threat, he smiled and said, "Qin will not give the second prince this opportunity."

Not to mention that he is a time traveler who knows the direction of history's development, even if he doesn't know, he will not choose to curry favor with Emperor Jianwen when Zhu Di has a great advantage.

The only one who can do that stupid thing is his unlucky uncle.

Zhu Gaoxu left, and then Zhu Di asked, "Who do you think you should go to the city if you want to go to the city?"

These are all established things that have been made, and there is no need to consider them much.

Qin Feng opened his eyes and replied, "I thought I could just look for Duke Cao. I heard that Duke Cao was guarding the city with King Gu at Jinchuan Gate, and the drainage pipe city is located near Jinchuan Gate. The most important thing is that Duke Cao once fought against His Highness. He knew that His Highness had made good intentions and would not refuse the boy's lobbying."

The established historical development was decided by Zhu Di, and Qin Feng considered the established historical development in accordance with Zhu Di's expectations.

Zhu Di was still satisfied with Qin Fengming's keen judgment.

Then he asked again: "If you enter the city, what should I do?"

Since they were sent out, they were from the Yan army. In order to ensure that they were safe, they would need to provide all the conveniences they could provide.

Lobbying is based on verbal skills, and everything else is second.

Qin Feng didn't ask so much, and replied: "In addition to filing a letter to prove his identity, the prince also had to forgive Duke Cao and King Gu for not guilty, so as to avoid their worries. The only thing left is for the boy."

This requirement is reasonable.

"What do you want after the matter is done?"

Rewards are necessary in terms of merit and merit, but I am afraid that Qin Feng will have unique requirements that Zhu Di cannot meet.

Qin Feng smiled and said, "If you say that the boy didn't ask for it, it would be a lie to your highness. However, if you say that the big request is not enough, the boy wants to find a support to make a living. His father is gone, and the boy just wants to protect his mother from being bullied by anyone."

This is the most real and very easy to be accepted.

As for using this achievement to offset the possible involvement of his unlucky uncle in Qin Feng, he did not say.

His uncle just said that he had defected to the court from the Shangyuan County Magistrate, and the specific situation is still unknown.

What if his uncle was just trapped in the city for various reasons, wouldn’t he cause trouble for Zhu Di in advance?

The cause, after and as a result, Qin Feng explained clearly, and Zhu Di was about to compromise.

Just as Zhu Di decided to hand over the last credit of the Jingnan Campaign to him, a sudden voice sounded at the door of the self-operated tent.

"Your Highness, this son has no idea of ​​his origin and is not sure. He sneaked into the camp and was afraid that he had already understood the situation of our camp. If he did it carefully, he would inevitably lead troops to attack once he entered the capital. He had to guard against it in order to ensure that he had no mistakes."

Who is this guy? Why are you so annoying?

"The dog son is of the same age as this son. He lived in Beijing for several years. He only went to Guangxi for a companion last year. The dog son knew the roots and the dog son was a hundred times better than this son as a messenger."

Bah, the shameless dog thing, it turns out that it is here to grab the credit.

He talked hard for so long, but he could just pick up the ready-made ones.

"I wonder if this gentleman respects his surname?" Qin Feng asked.

He had to see how much weight this person had in Zhu Di's mind, and it would be easier to decide how much effort he could take back what belonged to him.

Even if you can't get it back, you have to know who to settle the score.

"Chen Ying."

No wonder.

Chen Ying was one of the five treacherous ministers of the Yongle Dynasty. He served as Zhu Di's vanguard to destroy the remaining party of Jianwen, and also liked to criticize his colleagues the most.

In history, Sheng Yong, Geng Bingwen, Li Jinglong and Mei Yin were all in his hands.

"So it's Censor Chen."

Chen Ying may not be a big shot in front of Emperor Jianwen, but was a good official here. Zhu Di trusted him very much.

In comparison, Chen Ying's son is indeed more trustworthy than him.

It can be seen that the balance in Zhu Di's heart has turned to Chen Ying.

Chen Ying had helped Zhu Di do something when he was a deputy in Peking.

It was also because of this that Chen Ying was sued and exiled to Guangxi.

Whether it is out of trust, overall consideration, or to compensate Chen Ying, Zhu Di will not give Chen Ying a face for Qin Feng, a mere boy.

"Your Highness..."

Qin Feng's defense was pale and powerless under Zhu Di's consideration of the overall situation.

Damn it, after spending a lot of time, I made wedding dresses for others.

"Qin Feng...little brother..."

Halfway through Zhu Di's words, a monk wearing a monk's robe hurriedly approached with a letter in his hand.
