?Conference Hall, Yuwen Wen, who had not finished dinner, met someone who had just arrived from Jiangbei to communicate emergency military information. The other party was sent by the governor of Hengzhou Zhou Fashang to Xiyang, Bazhou Prefecture, and found him. After learning that he was in Yanji, Jiangnan, he quickly took a boat to hand over a letter.﹍>>Bar ｗ·ｗ·ｗ·．

"Envoy Yuwen, my husband said this is a big deal. Please make sure you decide quickly."

Yuwen opened the envelope and took out the letter paper, looking at the dim light of the oil lamp. As he looked at it, his eyebrows were frowning but there was no other movement. He then looked at it for a moment, putting away the letter paper and taking out a map from the bookshelf and unfolding it on the desk table. He held the oil lamp in one hand and looked at some point on the picture.

The maps of this era are completely incomparable to those of later generations. The maps of this era have various survey methods to carry satellite photos, so the accuracy is extremely high. The maps of this era will not only be proportional deformation, but also the basic distance will be deviated from reality.

In short, many map surveying and mapping methods are mostly map drawing methods, and then projection drawing methods. As for the method of painting methods, it will be until the fifteenth and sixteenth century. Maps such as county annals maps all look weird and extremely distorted in proportion.

Of course, there are also maps obtained by using scientific drawing methods, but most of these carefully drawn maps are military and national weapons that are not easily displayed. For example, Pei Xiu, the minister of the Wei and Jin dynasties who drew the "Yugong Regional Map", proposed the mapping theory of "Six-body Map of Maps", but this kind of map drawn by "high-tech" is rare.

Fortunately, the commonly used maps are also in a very good position. Yuwen Wen has gradually adapted to the "freehand painting" style after seeing too much. However, every time he looks at it, he has to think about the height of mountains, rivers and terrain. It will not really turn into a joke on paper.

He looked at the map attentively, and the person who came to report the news stood quietly without saying a word. Zhang Yu stood beside Yu Wen Wen with a natural expression, but he was secretly guarding himself. There are countless things in which he used to assassination in the name of publicizing emergency military information or important matters in the past few days, but he dared not be careless.

Zhang Yu had seen the person in front of him as an acquaintance. The other party followed Zhou Sanlang and Zhou Faming to Xiyang City at the beginning of the year, but even so, he had to be careful not to know what the other party was thinking. As the only inseparable follower in the military camp, Zhang Yu had a heavy responsibility on his shoulders.

Now the three of them in the conference hall are not allowed to inquire about military information because they have nothing to do with military law. The person who came to call him and reported to Yuwen Wen, so the other generals could not come in and listen before Yuwen Wen nodded or spoke.

Therefore, if something happens, only Zhang Yu can protect Yuwen Wen's personal safety. However, after two years of training, he has been able to be loose on the outside and tight on the inside without making people notice something strange.

"You were also at the scene when the envoy Zhou sent me to detect the military information in the letter?" Yuwen Wen suddenly asked, and the man nodded and said that it was precisely because he was also one of the detectives. In order to facilitate the envoy Yuwen, he sent him a few to deliver the letter. ＿﹍8 ｗ= ◗-．

"What are your routes for the surveillance? Click it on the map."

"Yes, I'll be here after the order of the Lord that day, and here..." The man walked up and reached out and pointed his hand on the map and pointed it out at the same time. Yuwen Wen fell into deep thought as he looked at the map, while Zhang Yu quietly pressed the knife with one hand to guard against an emergency.

Fortunately, everything went smoothly and nothing unusual happened. Yuwen Wen asked for a long time and then clapped his hands and asked the soldiers guarding outside the door to come in and ordered: "Let Chen Tongjun come here."

"Also, prepare the boat now."

......

In Xiyang City under the night, a carriage was escorted by more than ten riders on the empty streets. It was now curfew and there were no pedestrians on the street. A patrol team who turned around the street came up to see someone walking at night. Seeing the lanterns of the state yamen hanging in front of the carriage, they knew that this was the yamen team, but they still went forward to ask.

According to the rules set by Yuwen Envoy, no one is allowed to walk around the city unless it is a major event. The patrol team meets people walking on the street and asks them no matter what their identities are. If there is an emergency official business, they must register their names and what they are doing for later investigation.

If something happened in the night city, these registered people were the first suspects and they should be interrogated by the state government at any time to eliminate the suspicion. If someone was found out by Yuwen Jun, he would not be a joke. It is not a joke to walk around at night, because the night security in Xiyang City has improved a lot.

"It turned out to be the envoy of Yuwen!" The patrol leader quickly saluted when he saw the token raised by Zhang Yu. Now the war in Jiangnan is in a hurry and they know that the envoy of Yuwen is leading troops out of the battle. As a result, the envoy of Yuwen is actually returning to the city tonight, and he is afraid that he will delay important matters if he stops the car. Zhang Yu smiled and said that the envoy knows that you have worked hard on the patrol and devoted himself to the public, so he will not take it seriously.

The patrol team looked at the direction of the carriage. The state yamen was very concerned about Yuwen's envoy who had just returned from the state yamen's business, so they made way. The carriage slowly drove forward and they looked at the back of the team and started to talk.

"It seems that Yuwen Envoy hasn't been in the city for this time, right?"

"Who said no, the official army won one battle after another in Jiangnan. Yuwen Envoy really can fight!"

"I heard that those soldiers who participated in the war had made meritorious service and got rewards. If I had known I would have joined the army, I would have joined the army!"

"Come on, your moral character is still in the army. Don't go to the battlefield to wet your pants..."

"Don't joke about people..."

A faint laughter came, and Yuwen Wen, who was sitting in the car, closed his eyes and rested. After receiving the emergency military information, he immediately took a boat from Yanji in Jiangnan to land in Bakou. He first went to the Hulin Army barracks and then entered the city by car. He went to the state army barracks and the state yamen to Sima Yang Ji, who was on duty. After explaining important matters, he remembered that he still had his home in the city.

"I almost passed by the house three times and stopped entering..." He murmured to himself. During this period, he was leading troops either beating Chen Jun or on the way to beat Chen Jun. After spending a long time, he almost forgot to go home to check it out.

The carriage stopped in front of the Xiyang County Duke's mansion, but Yuwen Wen did not get out. Seeing that the night was already deep, he was worried that he would make too much noise when he returned home, which would make his family who should have fallen asleep easily catch a cold again, so he asked Zhang Yu to go in and have a chance of catching a cold first.

After a while, Zhang Yu led the butler Li Sanjiu out. After Yuwen Wen heard Li Sanjiu report that his wife and both wives were asleep, he asked him to tell him tomorrow that everything was fine and there was no need to worry about it.

"Does the man go back to the house to rest for one night? I'm so young that I have someone to prepare hot water." Li Sanjiu asked.

"No, I have important things to do, and everything in the mansion will be the same."

After a while, the carriage drove eastward under the escort of the rider. Yuwen Wen entered the city from the east gate. Because of the curfew, the east gate closed for a long time before he was able to successfully open the city gate. Now if you want to leave the city, it will be better to return on the same road, so you will not have to suffer any further setbacks.

The city gate slowly opened, and there were already a black cavalry outside the city waiting for a long time. Yuwen Wen got out of the car and walked out of the city and saw a man coming forward: "Master Lang... Envoy, we are ready!"
