Xu Da took two bamboo tubes, one of which was charred black and seemed to have been roasted by fire, and one end of the bamboo tube was sealed with cement, but it had been disassembled, and a roll of tin foil could be seen stuffed inside the bamboo tube.

"The last general didn't know that it was a secret from the city, so he rashly opened it and asked the marshal for forgiveness."

The handle on the Pingjiang city wall is tight, and Xu Dake has never had any information exchanges with the city, "Who sent the secret?" ”

"It's the Ma Du thing who stayed in Hongdu! Just open it and see. "Xue Xianjiu didn't know Ma Du's current situation in Jiangxi.

"Oh?!" Xu Da hurriedly took out the tin foil, and after opening it, there was a small paper roll inside, and when he opened it, he saw the dense strange characters written on it, and he didn't recognize any of them, "What does this mean, Xue Xian, do you recognize it?" ”

Xue Xian shook his head, "The last general doesn't recognize it, but this should be written by Ma Dushi, and the last general has seen him write the same character on the new city gate of Hongdu." ”

"You go to the Shenji Camp and invite Commander Zhu over!" Xu Da commanded his own soldiers again, and said to Xue Xian: "How did you get it?" ”

"It fell from the sky!" Xue Xian explained: "There are two Kong Ming lanterns floating in the city to the camp of the last general, and this bamboo pipe was found on the Kong Ming lantern. ”

"Kong Ming lantern?" Xu Da sneered, "This strange method seems to be used by him." ”

Xue Xian asked tentatively: "Didn't you say that this Ma Dushi is the prince's brother-in-law, how did he run to Zhang Shicheng's territory." ”

Xu Dadao: "It's a long story, you must remember to keep it secret, otherwise military law will be engaged!" ”

After a while, Zhu Wenying was invited by his own soldiers, he took two small notes with the same content, and said, "Oh, this is arithmetic, it was passed on by my uncle?" ”

"Yes, what do you mean?"

Zhu Wenying shook her head, "I haven't studied arithmetic and don't understand, but Xiaobiao has learned from my uncle, so I should know what it means, I'm afraid it's urgent news, and I will be delayed back and forth for several days." ”

"Since the prince has learned, there is no other way now, and this can only be so." He immediately wrote Chen Tiao, together with two bamboo pipes, and asked people to send them to Yingtian overnight.

Zhu Wenying said: "How did Uncle Xu's secret letter come out?" ”

"Kong Ming lantern!"

"Ah, my uncle can play."

Xu Da reprimanded: "Nonsense! Where is this playing, he is walking on the cliff, dancing on the tip of the knife, as dangerous as a soldier who braves the arrow and kick the city, you don't worry about him and tease him, how can there be a nephew like you. ”

"The subordinates know that they are wrong, and they will apologize to him when they see their uncle!" To say that Zhu Wenying is not worried about Ma Du's fake, but at the same time he is very relieved. In his heart, he has a kind of worship for Ma Du similar to Lao Zhu, and always feels that he is omnipotent and can survive in desperate situations.

Pingjiang and Yingtian are not far apart, and they ride fast horses for three days to go back and forth, and the strange characters on the paper scroll have become words.

Zhu Wenying frowned after reading it carefully and asked, "This is the strategy that my uncle gave us to break the city?" It's not like ah, how could he come up with such an idea, don't it be a misunderstanding of Xiaobiao? ”

No wonder Zhu Wenying questioned it, digging tunnels to bury explosives is indeed a bit dirty and stupid compared with Ma Du's previous magical methods, which makes people suspicious.

Xu Da held Zhu Biao's reply in one hand, flipped through the pages of the words in his hand with the other, and said after a while: "The prince has no misunderstanding, you see that this strange symbol is actually another kind of number, referring to the first few lines, columns, and words, all of them match, and the text is smooth. Shiko also said that he had played this game with Genzhong before. ”

That's right, this is just a numbers game that Ma Du and Zhu Biao and Xiao Turtle have played together. Ma Du looked through Song Ke's collection of books in order to find the same edition of "Shuo Wen Jie Zi", and Song Ke thought that this sister-in-law was studious and progressive.

Zhu Wenying said solemnly: "Uncle Xu, I have a bad premonition, don't my uncle was arrested by Zhang Shicheng, and forced my uncle to pass on false news to us and set us up." My uncle had been in the city to deliver messages to us, and I hadn't seen him for a long time. No one has ever used this method of blowing up the city wall before, who knows if it can directly blow up the city wall, don't Zhang Shicheng's gunpowder workshop was destroyed, so I want to use this method to consume our gunpowder. ”

Xu Da smiled, "It's not impossible, it may also be Zhang Shicheng's delaying tactic." ”

Zhu Wenying nodded, "What did my father say?" ”

Xu Da smiled helplessly, "If you don't accept the foreign monarch's order, we will decide ourselves!" ”

They really thought too much, and they didn't go to the city wall to deliver the news, first, it was inconvenient to go, and second, so much content couldn't be expressed in flag language. If he knew that he had finally thought of a big move, and he thought that it might be Zhang Shicheng's conspiracy, Ma Du would have vomited blood in anger.

In order to pass on this news, Ma Du took a risk, and this risk has already appeared, Chen Bao took someone to find the Song family, but not to find Ma Du, but to find Song Ke, the problem appeared on the paper of the sticky hole.

It turned out that one of the three Kong Ming lanterns released by Ma Du was shot down by the defenders with a strong crossbow at the head of the city, and then it was sent to Zhang Shicheng.

Although I don't know what is written on it, it can be concluded that it was the fine work in the city that contacted Zhu Jun outside the city. Lao Zhang immediately asked people to track down, and the most obvious thing on the Kong Ming lantern was that kind of high-grade rice paper.

Although this kind of rice paper is expensive, but the rich gentry in the city countless dozen taels of silver are nothing, but this kind of special except for the kind of good calligraphy and painting, the general rich gentry will not use it, but the damn shop has a buyer record, and the huge Pingjiang only buys this kind of paper more than 20 households, so I found Song Ke.

"Huh...... It turns out that this is the case, and Song should cooperate with this kind of thing. Song Ke took a roll of paper from the bookshelf and came down, "A few days ago, my little sister used some to make river lanterns!" ”

Chen Bao took it and handed it to a shopkeeper next to him, and the shopkeeper looked at it himself before saying: "It's this kind of paper, yes, but it's new paper, Mr. Song's paper has been around for many years, and the small shops that sold it before have records." ”

"See?"

The shopkeeper said with a smile: "It's not wrong, Mr. Song is my Pingjiang celebrity how to do such a thing, the villain thinks that this bad guy should be the young man with a mole on his face, and the name and address left are all fake, and it was only ......bought in the past two days" Seeing Chen Bao glaring at him, the shopkeeper immediately shut up.

Chen Bao got up and apologized to Song Ke again: "Chen is really trying to track down the meticulous work, which undoubtedly offends Mr. Song, and I ask Mr. for forgiveness." Chen is going to the next one! ”

"It's okay, how can Song be such a stingy person, hehe...... Xuanzhong will send me a Chen commander! ”
