Zhang Zhao said that Confucianism is not against technology, but only against strange skills. This is only half true, Confucianism is indeed not against technology, but the purpose of reading is to learn and excel, Zuo Jun Zhi Yao Shun, few scholars are willing to spend time on specific technology, so although the technology of the entire Han Dynasty has been improving, the requirements for culture are higher, and the technology that requires the participation of scholars is lackluster, and even regressed.

This is the case with mapping techniques. The importance of maps, especially military maps, is self-evident, during the Warring States Period, the map drawing technology has developed rapidly, and it has been quite mature by the time of the Western Han Dynasty, and the map unearthed by Mawangdui is basically consistent with the actual terrain, which makes people very curious about how the ancients did it. But all this came to an end, and since then there has been no progress, and even regressed, and no one in the Three Kingdoms period could draw such a map, so that Pei Xiu thought that the mapping technology of the Han Dynasty had always been like this, and regarded it as a slippery.

In this way, he has seen the maps of the early Western Han Dynasty, and he will definitely slap himself twice.

Mapping is not like the common technology in life, there are certain professional requirements, the scope of communication is narrow, the master and apprentice pass on from one to another, once there is a break, it may cause distortion or even loss, and the change of place names, tracing back to the source also requires a certain cultural literacy, the participation of readers, otherwise after a period of time, the change of place names, even the original map can not be recognized, let alone innovation.

However, since the Eastern Han Dynasty, advocating Confucianism, reading the scriptures and entering the office, people who can read have gone to read Confucianism, who wants to draw a map.

Maps are not well drawn, let alone making dioramas. Sun Ce had thought about such a thing a long time ago, but he didn't have a detailed and accurate map in his hand, let alone the terrain. Lu Yi put forward such a suggestion, and a few months ago, he really couldn't do it, but now, he has preliminary conditions. The scouts presided over by Guo Jia have explored the situation around Yuzhou in detail, and they also have a certain understanding of the terrain and water system distribution.

Sun Ce said that he would do it, and asked the craftsmen of the baggage camp to first put together a wooden plank three zhang long and two zhang wide, enclosed on all sides, and drew a plan on it, and then found scouts in charge of each area, and asked them to pile up the mountain shape at the corresponding position on the wooden board with mud and mark the river. There are not many mountains in Yuzhou, but there are many borders, the south and southwest of Runan, the northwest of Yingchuan, and the northeast of Peiguo, there are some mountains of different scales, the important thing is water, there are several big rivers in Runan, the direction is easy to determine, but the location is somewhat inaccurate, and it can only be rough in scale.

Contradictions soon appeared, so the scouts argued over the specific location of a certain landmark.

Lu Yi was stunned and a little remorseful. Sun Ce was already very busy, he wanted to help, but he didn't help.

Sun Ce was mentally prepared. "You see, the mountains and rivers are all in front of you, and there will be nothing that will change in decades or hundreds of years, and they are different in everyone's eyes, let alone those things that are invisible? They're the best scouts and don't mess around, but if they don't model it, they'll think they're right all their lives, and others think the same way they do. Mountains and rivers are easy to do, where is where it is, what is what it is, and you can distinguish right from wrong by sending someone to measure it. What about those truths that cannot be seen or touched, and who will judge who is right and who is wrong? ”

Sun Quan and Lu Yi were deeply inspired.

Sun Ce temporarily kept Sun Quan and Lu Yi by his side. Although he has some preconceived rejection of Sun Quan, this is prejudice after all, he is the eldest son, and he has a first-mover advantage, as long as he is not careless, Sun Quan will not have a chance to turn the tables at all. If his brothers can't be trusted and deliberately rejected, he has no one to use. Since you have to use it sooner or later, it is better to let them come into contact as soon as possible.

Sun Quan and Lu Yi followed Lu Meng to understand the situation, and Sun Ce saw it in his eyes and suddenly moved. The four governors of Eastern Wu, Zhou Yu has already taken charge alone, Lu Meng and Lu Yi are also under the account, only one Lu Su has not yet appeared, where is he?

Zhang Hong vacated a large camp in the camp and arranged 200 tents, and Sun Ce immediately issued an order: If the officers and men of the whole army have their families nearby, they can apply for their families to visit their relatives, and a tent can be arranged to reunite their families for three to five days, and those who have meritorious service and have trained hard are preferred. At the moment of the order, the whole battalion was in a sensation, and many people made applications, far more than two hundred, and there was a need to queue up.

Sun Ce handed over this decision to Sun Quan.

——

Jiangxia, Xiling City.

Liu Xun walked around the hall restlessly with his hands behind his back, looking up from time to time. Huang Yi hadn't come yet, he was a little impatient, and motioned to the guards to get the big fray, ready to go to Huang Yi in person. As soon as he tied up the big hat, Huang Yi hurriedly walked in from outside, holding a letter in his hand and looking happy.

"Good news, General." While laughing, he went up the steps, took three steps and made two steps, and came to Liu Xun.

"What's the good news?" Liu Xun was not in a good mood, and there was a bit of anger between his eyebrows and eyes that could not be concealed. He had a bad time during this time, and one bad news after another made him completely lose his patience. Zhou Yu entered Nanjun and approached Jiangling City, Huang Zhong and Li Tong were eyeing him, waiting for him to leave Yinling, he was in a dilemma, he couldn't sleep, he couldn't eat well, and his mood was very anxious.

"Yuan Yanzhou sent troops to attack Yuzhou, and the three roads went out together."

Liu Xun frowned, turning anger into joy. This is indeed good news, if Yuan Tan sends troops to attack Yuzhou, then Sun Ce is unlikely to attack Jiangxia, only with Huang Zhong and Li Tong, the traitors, it will be difficult for them to conquer Yinling City, and he can also divide a part of his men to support Chen Ji.

Liu Xun hurriedly grabbed the book and quickly browsed it. The book is written in the tone of Yuan Tan, which is very polite, but the handwriting is the handwriting of Xin Bi. After Xin Bi left Jiangxia, he sent news many times, and Liu Xun was no stranger to his handwriting.

After reading the book, most of the big stone in Liu Xun's heart fell, and a smile appeared on his face. "Zimei, last time there was no winner or loser, who will be the winner in this battle?"

Huang Yi smiled and said: "No matter who wins or loses between Yuan Yuanjun and Sun Ce, the general can sit back and relax." ”

"Oh?"

"General, although Sun Ce has Yuzhou, he is not valued by Shilin, and the talents and material resources in Yuzhou cannot be used by him. The strength of Chongzhou is slightly inferior, but after Yuan Yuanjun is famous, Yanzhou scholars gather under the tent, and there are many county guards and county orders from Yuan's family, and Jiyin and Shanyang Taishou are surnamed Yuan. With the strengths of one and the other, it is difficult for them to distinguish the winner in a short period of time. In this way, Sun Ce would not have the spare strength to attack Jiangxia, wouldn't the general sit back and relax? ”

"But Zhou Yu is heading towards Jiangling, Chen Ji asks me for help, but Li Tong and Huang Zhong are waiting to move, do I save or not?"

"Save, but not passively." Huang Yi raised his eyebrows. "The way of using soldiers is to cause people but not to people. I planned a clever plan for the general to encircle Wei and save Zhao and fight Wan in three ways. ”
