A Lu city has long been blocked, and Tatar cavalry can't rush in. How did this person appear here? It's understandable if he was already in the city, but how did he get the latest instructions from Zhongdan Gong? Was it haidongqing who reported, but he didn't see any birds entering the city. How to report.

No matter Ning Wenfeng or Shi Wanshan, they naturally don't know that there is another thing in the world. They don't need to meet at all. They can really communicate with each other, even unaffected by distance. Naturally, Yu can has no obligation to tell them all this. He can even think of each other's doubts, but his duty is not to explain these, but just to send letters.

Yu can, the leader of the Security Bureau in Dalu City, is usually responsible for collecting information in the city and forwarding it to director Feng Liang of Shicheng on time. I thought he would always be a dark worker, but today's telegram forced him to reveal his identity. That is, the sixth young master called in person and asked him to pass a word to the Yamen of the city Lord's mansion.

The sixth young master has orders, and he dare not disobey them. Yu can is here, but he is still here in a big and generous way. He knew that perhaps only by doing so could he dispel the worries of the two generals and complete the matter.

Ning Wenfeng's words were obviously a test, and Yu can replied with a smile: "there's any good tea there. The small one doesn't have a chance to drink. But if you doubt my identity, you can catch me as a liar."

Such a straightforward answer made Ning Wenfeng look embarrassed, and he didn't know how to answer. After all, it's no good pretending to be loyal and courageous at this time.

However, Shi Wanshan, who had been impatient for a long time, looked at the impasse in the conversation. He finally said, "Mr. Yu said he came by the order of Zhongdan Gong. What can you tell me?"

"Commander, I came here at the order of Lord Zhongdan. I really have something to tell you. According to the intention of Lord Zhongdan, if Lu city can't keep it, you don't need to keep it. Just return to Xuanfu city. You can accumulate strength to keep it..."

Yu canzhifang just said half of it, but Ning Wenfeng interrupted him, "answer why Lu city can't keep it. Besides, we eat the salary of the imperial court. Now the imperial court hasn't made an order, how can we leave our duty without permission? Mr. Yu, do you know that according to what you just said, we are already committing a crime?"

No wonder Ning Wenfeng is angry. Answer: whether Lu city is lost or not, Yang Chendong may not care too much, but as a general guarding the city, he will bear a great relationship. If he doesn't do well, he will be ruined and even beheaded in prison. When it comes to his own family and life, he is not in a hurry.

After Ning Wenfeng said this, Yu can closed his mouth, shook his head first, and then tasted tea. Not frightened by the other party's criminal words.

Yu can's calmness falls aside in Shi Wanshan's eyes, which can't help but shine in front of him. This person is so calm, either he has a dependency, or he has put life and death aside, but no matter what, he believes that no one will die for nothing. At that moment, he suppressed Ning Wenfeng, who was still angry, then smiled at Yu can and said, "Mr. Yu, you should still have something to say. The commander is willing to listen."

Shi Wanshan said so. Ning Wenfeng could only suppress his anger and stare at Yu can. He wanted to see what this person would say next. If he was talking nonsense, he would take it first and then say it, regardless of whether the other person is really loyal and courageous.

Yu can slowly puts down his tea cup, looks at Shi Wanshan and says word by word: "Lord Zhongdan said that Dalu city can be abandoned and Xuancheng can't be abandoned. As long as the commander guards the Xuanfu house and doesn't let the Tatar army move forward, Dalu city will return to the general's hands in one to two months at most."

"Oh?" Shi Wanshan's face was stunned. He had already known that there were still the following, but he didn't expect such a result. When his thoughts flew around, he seemed to think of something, "Lord Zhongdan, but do you want to deal with the Tatar cavalry?"

"Why? Didn't Zhongdan send troops very early?" Yu can smiled.

"Sending soldiers is sending soldiers, but you don't know by pretending." Ning Wenfeng finally had the opportunity to interrupt. At this moment, he doesn't know why. The more calm Yu can is, the more unhappy he is. When he comes to his own territory, his life is in his own hands. He can be so stable as Mount Tai. It's really annoying.

Yu can seems to be used to nitpicking Ning Wenfeng. Instead of answering his questions, he continues to say calmly: "I came here to deliver the message in the words of the loyal and courageous public. Whether you believe it or not is my problem. Of course, you can also arrest me and even torture me. I can't guarantee whether I can stick to my secret. But once I come, it will delay the time for the two generals to make a choice. Let's choose between the two."

After spreading everything on the bright side, Yu can continues to drink tea without saying a word, just like a thirsty person looking at manna.

This behavior is to put life and death aside. Often such people are not easy to bow their heads. Even if they are caught and executed, they will not have results in a short time. But Shi Wanshan doesn't have much time now. If he makes a mistake, he will have no chance to turn over.

"Mr. Yu, do you have any keepsake to prove your identity?" Shi Wanshan asked with some reluctance.

"No." Yu can answered very happily. Then he added, "answer Lu city has been closed. Where did I get the keepsake?"

"Without a token, where did you get the news?" Ning Wenfeng interposed again when he felt that he had caught the other party's loophole.

"It doesn't bother the general. In short, what I say is the truth. Believe it or not, the two generals will consider it by themselves." Yu can definitely won't tell the telegram, which is still a secret for other forces. Of course, the longer I hide it, the more favorable it will be.

Yu can, who did not enter the oil and salt, immediately gave Ning Wenfeng a feeling of no place to cut. Then he looked at Shi Wanshan, obviously to command and make decisions.

Shi Wanshan frowns. Yu can's appearance is too unexpected. He can't make any decision for a moment. He still needs more time to think about it. Then he slowly looked up, "Mr. Yu, thank you for telling me. In this way, I'll think about it and make a decision. Now please go back and have a rest."

"Well, you don't need to inform the grass people of the results of your consideration. Your decision will be known all over the world soon." Yu can knows that the task is completed and it's useless to stay, so he stands up, nods to the two generals and turns away.

Outside the door, when the waiting soldiers escorted Yu can away, they saw a sign in Shi Wanshan's eyes. At that time, they gently forehead to show that they understood his meaning.

As soon as Yu can left, Ning Wenfeng said anxiously regardless of others, "commander, you don't really believe that he was sent by Zhongdan Gong? He doesn't have anything to prove himself."

"If you can't go out, how can you prove it?" Shi Wanshan asked back and said, "at this moment, do we have another way to choose?"

"But... But why did Zhongdan do this?" Ning Wenfeng asked in a different way.

"Didn't you say that Zhongdan wanted this supply road, that's why." Shi Wanshan suddenly got up, as if he was persuading himself, or maybe he had made a decision in his heart.

Yu can leaves the city master's house, returns to his own courtyard, and soon turns out the light and goes to bed. There was nothing wrong with the soldier sent to follow him, so he had to send someone else to keep him. He rushed back to report the situation. In this regard, Shi Wanshan has long been prepared. Even if yu can dares to appear, he will naturally deal with everything first and last.

He knew that it was impossible to find the answer from Yu can. But Shi Wanshan will not want to let him go. Once he leaves Dalu City, he will take him away. If he is not sent by Zhongdan Gong, he will kill him before he dies.

That is, from the beginning of the night, the northern Ming army was ready to retreat, and the carriages transporting grain and grass to and from the Xuanfu house kept coming and going. Three days later, Shi Wanshan, who had been guarding very hard, was finally ready to leave the city when the night came. In order to prevent being discovered by the Tatar army, he left two hundred houses and asked them to keep walking on the tower with torches, creating a false image that the army is still there.

Shi Wanshan finally decided to believe Yu can's words and withdraw from Dalu city. When he and song Wenfeng got out of the city master's house, Yu can, who was already carrying a package, was waiting here in front of the main gate. Obviously, he also knows that the other party will not stay here. It's better to take the initiative and leave with them.

Yu can is so knowledgeable that Shi Wanshan, who has not yet planned to turn his face, walks over with a smile, "what does Mr. Yu mean? Do you want to leave with us?"

"There are no northern Ming army and people in the city, and can has no value to stay here. He has to bother the commander." Yu can stood there with a smile on his face, as if he had no way to go.

"Hehe, good. Somebody, prepare a batch of good horses for Mr. Yu and leave the city with me." Shi Wanshan laughed. Whether Yu can is loyal to the public or not, he already appreciates it with this courage and insight.

In the dark, the torch went away. The northern Ming army retreated from Dalu City, leaving an empty ancient city without any resources.
