Zheng Xuan once entered the Taixue to study "Jingshi Yi", "Ram Spring and Autumn", "Three Unification Calendar", "Nine Chapters of Arithmetic", and studied under Zhang Gongzu "Ancient Texts and Books", "Zhou Li" and "Zuo Chuan", etc., and finally studied under Ma Rong to learn ancient scriptures, returned to study and returned to the country, returned to the guest to cultivate Gaomi, gathered apprentices to teach, disciples amounted to thousands, the family was poor and studious, and finally became a great Confucian, the disaster of the party was imprisoned, Du Men annotated, devoted to writing, and the study was mainly based on ancient scriptures, and adopted modern scriptures.

He paid attention to the Confucian classics, sorted out the ancient texts with his life's energy, unified the scriptures, and wrote books such as "Seven Political Treatises on Astronomy" and "Zhonghou", with a total of more than one million words, and was known as "Zheng Xue".

Such a person, the world is famous, but also because of its Qingzhou background, Qingzhou is all praised, you Heng compared, but it is very different, but it is not as good, hearing Cao Cao's intention to make Zheng Xuan help, You Heng thought for a moment, shook his head and said: "Zheng Gong is dedicated to studying, I am afraid that he has no intention of helping." Cao Cao laughed and said: "Zhikang Chenggong has always been elegant and does not follow the world, and you make Jun is the disciple of Kang Chenggong's grandson, if you make Jun worship him, how can he refuse it?" ”

"What's more, the tongue of the king has already heard of it, why not provoke it or two, and worry about it?"

You Heng frowned, this time, if you can persuade Zheng Xuan to help, it can't, if Zheng Xuan is willing to give some surrender order, it will definitely be much more effective than his own family, You Heng simply no longer refused, nodded and said: "There are not many soldiers, you can guard Linyi, I can go to Gaomi with you and persuade Kang Chenggong!" ”

"That's great!" Cao Cao worshipped, You Heng and Linyi stayed with Cao Cao for a night, during which they talked about the livelihood of the world, but the two talked very happily, quite a little difficult to leave, so they called the slave to hold the lamp, the two talked with candles and nights, as for the next day, together with Cao Cao, led more than 1,000 knights, to Gaomi.

You Heng looked at these knights, although they were wearing Han armor, but they did not seem to be county soldiers, or with You Heng's corporal general, they were the private soldiers of the Cao family, Cao Cao was the eldest son of Cao Cao, and it was reasonable to get the help of the Cao family, You Heng and Cao Cao walked side by side with the front, and more than a thousand knights galloped towards Gaomi, along the way, the thieves did not dare to stop them, the knights were different from the foot soldiers, the thieves could not pursue, they could not surround them, they could come and go freely, and they dared to ask for trouble.

"Zhengping, if you can get Zheng Gong's help this time, what should you do?" After some time of conversation, Cao Cao also became much more cordial to Youheng, calling Zhengping, not the envoy, You Heng said with a smile: "You can make Zheng Gong a letter, copy and deliver it to the whole state, so that the thief will abandon Ge and return to his hometown. ”

"Such a great good!" Cao Cao nodded, and then asked, "If Gong Zheng doesn't want to, what then?" You Heng didn't answer, but tilted his head, looked at Cao Cao, and asked, "I don't know what will happen to Meng Dedang?" ”

"One wrote a letter privately in the name of Zheng Gong, and the other forced him with a sword!" Cao Cao didn't care about it at all, and said with some categorical words, You Heng was stunned for a moment, laughed, nodded and said: "If you are a generation of Confucians, you don't think about serving the country and the people, and the sword can be used." ”

After half a month, as for the outside of Gaomi City, it was a surprise, the Gaomi City Gate was wide open, people came and went, the thieves were extinct, the people were as always, there was no abnormality, Cao Cao and You Heng looked at each other for a long time, and then led everyone slowly to the Gaomi City Gate, but there were two soldiers chatting and talking, Cao Cao hurriedly asked: "Now Qingzhou is in chaos, why is it safe here?" The soldier smiled and said: "Kang Chenggong lectures with this, so the thieves avoid it, and the officials and soldiers do not commit it." ”

"Alas~" Cao Cao shook his head, threw the jade plate on his waist, and said: "I am Cao Cao, the prime minister of Jinan, and this is the captain of the school, You Heng, you can record it." At the gate of the county seat, it is to record the situation of people entering and leaving, so as to protect the door, so that the soldiers remember, as for the city, there is no scene of war at all, as usual.

You Heng and Cao Cao dismounted and walked slowly, as for a mansion, You Heng just stopped, but Cao Cao came here for the first time, saw this somewhat damaged mansion, looked around, and said with some emotion: "Poverty is like this, it is really a great Confucian." You Heng stepped forward and knocked on the door, and a servant slowly opened the door, seeing that everyone was stunned, he leaned over and said: "This is the mansion of the Duke of Kangcheng, I don't know what the kings command?" ”

"I'm Youheng, tell me quickly!" You Heng waved his hand and spoke.

"It was your envoy, so I will tell you!" The servant was stunned for a moment, and hurriedly saluted, and immediately trotted in, and after a while, he immediately welcomed You Heng and Cao Cao into the mansion, and entered the mansion, where many scribes were reading and debating, and saw that You Heng and Cao Cao were not paying attention, and turned a blind eye, but they were extremely rude, and Cao Cao and You Heng were not angry, and walked through the corridor, and as for the mansion, they saw an old man writing something.

You Heng stepped forward to salute, but was stopped by Cao Cao and whispered; "We have a request for others, and we cannot judge people Yaxing." , Hearing what Cao Cao said, You Heng stopped, looking at Zheng Xuan, Zheng Xuan is more old than a few years ago, his beard is gray, but he is not thin, at this moment he is in a hurry, where the interest is, You Heng is not easy to break, so he concentrated on waiting with Cao Cao, and waited for a long time, but Zheng Xuan still wrote.

"Don't you know what we mean, so you want to resign?" You Heng thought about it, and slowly frowned, if it wasn't for Cao Cao's pull, I was afraid that he would have stepped forward to speak, and when he was thinking about it, he saw Zheng Xuan throw the pen away, looked at You Heng and Cao Cao with a smile, and said: "I haven't seen each other for a few days, and Zhengping and the temple have already gone up." You Heng bowed his hand and said: "Ziheng worships Kang Chenggong and asks Jun An." ”

"Cao Cao of Chenjun worshiped Gong Zheng and asked Jun An."

"Wu'an, don't be polite, and sit." Zheng Xuan waved his hand, and knelt in front of the two, You Heng and Cao Cao sat one after another, looking at Zheng Xuan, You Heng was about to speak, Zheng Xuan said again: "There are a lot of thieves today, why are they?" You Heng squinted his eyes and said, "Life, if you can survive, why is this so?" Cao Cao shook his head and said: "Those who ask for food also eat, and the people take food as the sky, and it is really because there is no food that they make chaos." ”

"Reasonable, reasonable." Zheng Xuan nodded, and then said: "How can we make the people live and have food?" ”

You Heng and Cao Cao looked at each other, and You Heng said: "Qingzhou is close to the river, if the water conservancy is greatly developed, the coming year will be a good year, if the people are made to repair water conservancy and distribute food, it will definitely make the people have a job and not become thieves, but I don't know about it, or the national teacher has seen it." In this regard, Guoyuan is several times better than Youheng, Zheng Xuan nodded, and Cao Cao said: "Qingzhou, the rich have thousands of acres, or they can severely punish the unkind local tyrants, so that their fields can be filled with grain and scattered with the people, so that the people can live." ”

"In this way, you can wait." Zheng Xuan handed over the things he had just written to You Heng and sent them off.

You Heng hurriedly said: "We are coming, but we have something to ask!" Cao Cao pulled You Heng again, You Heng turned his head and saw that Cao Cao was looking at the things in his hands, You Heng looked down, but it was a surrender order, You Heng was shocked, and hurriedly said: "How did Gong Zheng know that we are here for this matter?" Cao Cao said with a smile on the side: "Princess Zheng Xiuyi, such a trivial matter, how can you not know that Gong Zheng's great talent can't be used for the country!" ”

You Heng didn't believe in any fortune telling from the heart, but he also solemnly bowed to Zheng Xuan, and only then left with Cao Cao, looking at the persuasion book in his hand, You Heng was slack in his heart, if he could persuade most of the chaotic people in Qingzhou to abandon their hometowns and return to their hometowns, You Heng would be able to get along and sort out Qingzhou's agricultural affairs, and there were a large number of celebrities in Qingzhou such as Guoyuan to help, why worry about the people again?
