Cao Zhang returned to the mansion with a heavy heart, turned over and dismounted in front of the gate, threw the reins to the family, and walked towards the mansion with his head down.

"Childe, Childe Xiahou and Miss were here just now......" Jiading hurriedly reported to Cao Zhang.

Cao Zhang's mind was full of questions, and he waved his hand to Jiading, who looked at him with a sad look, didn't dare to say anything more, and closed his mouth.

Cao Zhang walked slowly towards the gate, but before he entered the door, he heard Xiahouba's excited voice from the courtyard: "Brother Meng Qi, are these ten horses really for me?" ”

"That's natural, this is all carefully selected by me and Ziwen for you, he said that this is the bet that he lost to you at the beginning, and it must be cashed out." Then Ma Chao's voice also sounded in the courtyard.

"Great, great. Brother Meng Qi, tell me quickly, how to choose this horse, and I will also learn from you. Xiahou Ba shouted excitedly.

"Come, come and see, this horse selection, first of all, depends on the color of the coat. If there is no variegated horse, it means that the bloodline is pure, and there is an innate advantage......" Ma Chao talked eloquently and began to explain and introduce.

Hearing the conversation between the two, Cao Zhang's originally depressed mood instantly improved a lot.

He knew that his army had returned to Xudu, and it was Ma Chao who brought the good horses they carefully selected to Xiahou Ba.

Cao Zhangxin walked into the courtyard and saw that in the courtyard, Ma Chao and Xiahouba were standing next to the ten good horses, discussing passionately.

Ma Chao's eyes flashed with excitement and excitement, and he danced to explain the qualities and characteristics of the horses.

Xiahou Ba followed beside him, listening with an intoxicated expression, nodding in agreement from time to time.

Seeing them discussing the horse issue so engrossively, Cao Zhang couldn't help but smile.

Such a harmonious atmosphere is what he has always longed to see, and his generals support and respect each other, and work hard for a common goal, which is what he is most pleased with.

"Brother Ziwen!" Cao Zhang was thinking about it, but he heard a greeting.

He looked intently, but it was Ma Yunlu and Xiahou Juan standing under the corridor next to him, both of them had smiles on their faces, and Xiahou Juan was waving his hand at him excitedly to say hello.

Cao Chang nodded with a smile and walked up to the two: "Juan'er, Yunlu, you already know each other?" ”

"Yes, my eldest brother and I have been here for a while, and Brother Zhongquan introduced Sister Juan'er to me, and we talked about it." Ma Yunlu responded to Cao Zhang with a hearty smile.

"Sister Yunlu told me a lot of interesting stories about Yongliang, which is interesting. She also promised me that she would have the opportunity to take me there in the future. Xiahou Juan was also immersed in the story told by Ma Yunlu and seemed very excited.

"Okay, the scenery of Yongliang is indeed very beautiful, it is completely different from the Central Plains, you should take a good look if you have the opportunity." Cao Zhang echoed Xiahou Juan, and he felt very relieved to see that the two daughters got along so well.

"Ziwen, you're back, these ten horses are so good, I really like it." Xiahou Ba saw Cao Zhang coming back and greeted him excitedly.

Cao Zhang looked at Xiahou Ba and smiled: "Brother Meng Qi personally picked it for you, can it be bad?" This is a good horse, you have to perform well in the future, strive to go to the battlefield next time, and make more achievements! ”

"That's a must, don't worry!" Xiahou Ba agreed with a smile.

Ma Chao walked up to Cao Zhang and reported to him: "Ziwen, the troops have been led by Gongming and returned to the station, and Yanming and Ling Ming have stayed in the barracks. Mr. Yuanzhi has been away from home for a long time, and he is worried about his mother, so he will go home to visit him first and ask me to help him take a leave. ”

Cao Zhang nodded understandingly: "Yuan Zhixiao, he should let him visit his mother first." Let's go, let's go inside and talk. ”

Ma Yunlu had been observing Cao Zhang since he entered the mansion, and had already found that his mood was not high, so he asked with concern: "Brother Ziwen, you seem to be in a bad mood, have you not thought of a way to solve the problem?" ”

Cao Zhang turned his head to look at Xiahou Ba and complained to him with disgust: "Zhongquan, you said it with a big mouth again?" ”

"Oh, Brother Meng Qi and Yun Lu are not outsiders, and everyone will be relatives in the future, so I tell them that it won't be in the way......" Xiahou Ba muttered and explained.

Xiahou Juan heard the implied meaning in Xiahou Ba's words, and was a little embarrassed, avoiding Ma Yunlu's gaze.

"Yes, Brother Ziwen, Brother Zhongquan was also worried about you, so he told us about it. Tell us what's going on, and we'll help you with ideas. Ma Yunlu's attention was on Cao Zhang, and he continued to ask.

Cao Zhang knew that Ma Yunlu was very smart, and he could think of breaking Chang'an with water at that time, and now he might be able to help him develop his ideas, so he didn't hide it, and went to Xun Yu to seek advice, and finally he gave him a hint.

"Xun Lingjun's words are unfathomable, I thought about it all the way, and I still haven't figured out what he means." Cao Zhang said helplessly in the end.

Ma Chao, Xiahou Ba and Xiahou Juan were all confused after listening to Cao Zhang's narration, obviously they couldn't guess what Xun Yu's prompt meant.

Ma Yunlu frowned and thought for a moment, then asked, "Brother Ziwen, I want to know, what is the evidence of the report we have now?" ”

Xiahou Ba said for Cao Zhang: "It is a letter written by Li Dao to Dong Cheng, and it is mentioned in the letter that someone provided him with the military information of our army at that time. ”

Ma Yunlu clapped his hands and said with a smile: "Then things will be simple." Since Li Dao said that someone provided him with military information, then we will find a way to find a letter that provided military information, don't we know who wrote it? ”

Xiahou Ba shook his head: "What's the use of finding it?" Since someone wants to frame Dong Cheng, the affirmative letter is also written with Dong Cheng's identity! ”

Cao Zhang listened to Ma Yunlu's words, but he woke up in an instant, and said excitedly: "No, Yunlu is right, if you find the letter, you can prove who is collaborating with the enemy!" He can pretend to be Dong Cheng's identity, but we can still recognize the handwriting of the letter writer! ”

He was a forensic doctor, and he still knew a little about some simple methods of identifying handwriting, and he believed that as long as he could get his hands on the letters, he should be able to find a way to confirm them.

What's more, Cao Pi will definitely not find someone to write this kind of confidential letter, even if he deliberately imitates Dong Cheng's handwriting, but with Cao Cao, Cao Zhi and his own understanding of his handwriting, it is not difficult to determine whether it was written by him.

As long as it can be determined that the person who wrote the letter is Cao Pi, then he can be convicted!

Ma Yunlu once again found a way to solve the problem that Cao Zhang couldn't solve, Cao Zhang was excited, opened his hands excitedly, and wanted to kiss and hug again to celebrate: "Yunlu, you are really amazing......"

However, when he saw Xiahou Juan standing next to Ma Yunlu, he suddenly realized that this move was inappropriate, and hurriedly turned his outstretched hands into punches against the air to resolve the embarrassment.

Ma Yunlu looked at Cao Zhang, but he had already guessed his original intention, looked at him and then at Xiahou Juan, revealing a wicked smile.

Cao Zhang, on the other hand, was a little embarrassed and smiled awkwardly to avoid her gaze.

Xiahou Juan was innocent by nature, and he didn't understand what dumb riddles were playing between the two at all, but he just smiled happily and excitedly for Cao Zhang.

"Zhongquan, you immediately go to Li Huan and Li Ying, invite the two of them here, and say that I have something important and need their help!" Cao Zhang gave instructions to Xiahou Ba.

Xiahou Ba took the order and quickly went to the residence of the two, and it didn't take long to invite them to Cao Zhang's mansion.

Cao Zhang went straight to the point, explained his intentions directly to them, and asked them if they knew about "Dong Cheng"'s letter to Li Dao.

"Hui Gongzi, this letter is indeed there, and it was all collected by Li Dao himself at that time, but as for whether it was destroyed, we don't know. Even if it is preserved, it should be placed in his room in Chang'an Shuaifu. Li Ying said to Cao Zhang after listening.

"It's just that after a series of battles, we really don't know if we can find it now." Li Huan added.

"It's okay, just make sure you have this letter!" Cao Zhang didn't pay much attention to it, and after thanking the two, he personally sent them out of the mansion.

"Zhongquan, your good horse can come in handy now. Hurry to Chang'an now and look for that letter!" Cao Zhang sent the two away, and immediately turned back to give instructions to Xiahou Ba.

Then, he turned to Xiahou Juan and said: "Juan'er, didn't you just say that you were fascinated by the scenery in the northwest, then this time Zhongquan went to check the clues, you went with her, just to take a good look at the scenery over there." ”

Xiahou Juan was stunned for a moment when he heard Cao Zhang's words, and then understood his intentions, knowing that Cao Zhang was very fascinated by the northwest region when he heard what she just said, so he immediately arranged a trip for her and Ma Yunlu.

Cao Zhang loved her so much and took care of her mood, which made Xiahou Juan very pleased. The only regret is that she knows that Cao Zhang will definitely not be able to accompany her on this trip.

Ma Yunlu immediately answered: "Okay, then I'll go with Juan'er, I was in a hurry to come back with the army, and I didn't play in many places around Chang'an, so I went again this time, just to make up for it." ”

"Okay, with you with Juan'er, I will be much more relieved." Cao Zhang smiled with satisfaction.

When Xiahou Juan heard that Ma Yunlu was accompanied, his mood was much better, and a smile appeared on his face.

Xiahou Ba asked with some concern: "Can you find this letter in this way, what if you can't find it, isn't that a waste of time?!" ”

Cao Zhang looked at Xiahou Ba but smiled: "Then you must look carefully and carefully, it is best to find every place in Chang'an Shuaifu, so that Juan Er and Yunlu will have time to have a good time around Chang'an." ”

Xiahou Ba looked at Cao Zhang suspiciously, obviously not understanding what Cao Zhang meant by looking for a letter but not being in a hurry.

Ma Yunlu already understood that Cao Zhang was deliberately delaying time and detaining Cao Pi for as much time as possible.

She said to Cao Zhang: "Brother Ziwen, don't worry, we will definitely help Brother Zhongquan find it very carefully and carefully, and we will definitely not let go of any clues." ”

Seeing that Ma Yunlu was so smart and understanding, Cao Zhang looked at her and showed a knowing smile......

Ma Yunlu looked at Cao Zhang, and also showed a happy smile......

……

Cao Xiu's residence.

He was sitting in the study, with several military books and war strategies in front of him, and he was studying them carefully.

Cao Zhen hurriedly entered from the outside, staring at Cao Xiu in front of him.

Cao Xiu glanced up at Cao Zhen, and continued to look down at his military book quietly.

Cao Zhen saw that Cao Xiu was in a hurry, rushed forward, snatched the book of war from his hand, and threw it on the ground: "I'll let you see!" ”

Cao Xiu raised his head and glared at Cao Zhen dissatisfied: "Zidan, what are you crazy about?!" ”

"Zihuan is now locked up in the cell of the school office, Ziwen has been back for several days, and he has not been interrogated or investigated, he has been locked up like this, you are still in the mood to read here, and you don't want to think about how to save Zihuan?!" Cao Zhen angrily accused Cao Xiu.

"Save? Guan Zihuan is Sikong's idea, if he doesn't let go, who can save it? Cao Xiu responded to Cao Zhen helplessly.

"Then why don't we do anything and watch Zihuan suffer in prison?" Cao Zhen shouted unwillingly.

Cao Xiu stood up helplessly and comforted Cao Zhen: "Zidan, I know you're worried about Zihuan." But in the current situation, we just can't move. If we don't move, we won't make mistakes, and they won't be able to get any new grips. ”

"Dong Ji has committed suicide according to the prior arrangement, as long as Shi Ah also holds on and does not let go, they will not be able to get any evidence that can accuse Zihuan, and they will not be able to convict Zihuan, so we don't need to worry too much."

Cao Zhen listened to Cao Xiu's words and calmed down a little, but still said worriedly: "But the question is, if Ziwen can't find evidence all the time, will Zihuan be locked up all the time?" ”

Cao Xiu said confidently: "How is it possible? Don't say that we don't agree, and Zijian can't agree. Do you think that Yang Xiu suggested to Sikong that there was no purpose in letting Ziwen try the case, what he wanted was to stir up the conflict between Ziwen and Zihuan, so that Zijian could profit from it. ”

"Zihuan has been locked up, and there is no benefit to Zijian, how can Yang Xiu not take action?"

"What's more, do you think Sikong will be willing to let Zihuan stay in the cell all the time? He doesn't like Zihuan anymore, it's also his son, and it's the eldest son, without evidence, it's always closed, is Sikong's face good-looking? ”

"So we don't need to be in a hurry, naturally someone will urge Ziwen to investigate the case. As long as he can't find any evidence, sooner or later he has to release Zihuan, and our play will be really successful! Cao Xiu analyzed the situation and built confidence for Cao Zhen.

Cao Zhen listened to Cao Xiu's analysis, although he was still worried about Cao Pi in his heart, but there was really no better way at the moment, so he could only nod helplessly......
