In the conference hall, Yu Wenwen, who had not finished dinner, saw the person who had just arrived from Jiangbei to spread the emergency military information, and the other party was a messenger sent by Zhou Fashang, the assassin of Hengzhou, who rushed all the way to Xiyang, Bazhou Prefecture to find him, and after learning that it was Yanji in the south of the Yangtze River, he hurriedly took a boat to hand over a letter.

"Yuwen envoy, my lord said that this matter is not trivial, please make a quick decision."

Yu Wenwen opened the envelope and took out the letter paper, looking at the dim light of the oil lamp, looking at it with his brows tightly knit but no other movements, he looked at it like this for a moment, he put away the letter, took out a map from the bookshelf, unfolded it on the desk, held the oil lamp in one hand and carefully looked at a place on the map.

The maps of this era are completely incomparable with the maps of later generations, and the maps of later generations are extremely accurate because of various survey methods and satellite photos.

In short, most of the surveying and mapping methods of many maps are the planning method, and then the projection method, as for the longitude and latitude drawing method, it was not until the fifteenth and sixteenth centuries that the maps such as the county chronicle map look strange and the proportions are extremely distorted.

Of course, there are also maps obtained by scientific drawing methods, but most of these carefully drawn maps are military \ national sharp weapons that are not easy to show, such as Pei Xiu, the minister of the Wei and Jin dynasties who drew the "Yugong Territory Map", put forward the cartographic theory of "six bodies of cartography", but this kind of "high-tech" drawn maps are not rare.

Commonly used maps are good in the direction, the important geographical environment is also there, Yuwenwen has seen too much, and slowly adapted to the 'freehand' style, but every time I look at it, I have to make up for the terrain of mountains and rivers, so as not to really become a joke on paper.

He looked at the map intently, and the person who came to report the news stood quietly on the side without saying a word, Zhang Yu stood by Yu Wenwen's side with a natural expression, but he was secretly vigilant in his heart.

The person in front of him, Zhang Yu, has seen that he is an acquaintance, and the Zhou family when the other party came to Xiyang City with Zhou Faming at the beginning of the year, but even so, who knows what the other party thinks, as the only inseparable personal follower of the Lang master in the military camp, Zhang Yu has a heavy responsibility on his shoulders.

Now in the conference hall, the three of them are not allowed to inquire about the military situation because they have nothing to do with the military law, and someone who comes to report the urgent military situation to Yu Wenwen, so before Yu Wenwen nods or speaks, the rest of the generals cannot follow in to observe.

Therefore, once something happens, only Zhang Yu can protect Yu Wenwen's personal safety, but after two years of experience, he has been able to be loose on the outside and tight on the inside, without people noticing the abnormality.

"Zhou Envoy said in the letter that you were also at the scene when the military intelligence was sent?" Yuwen Wen suddenly asked, and the man nodded and said that it was precisely because he was also one of the sentinels, so in order to make it easier for Yuwen to understand the matter, Lord Lang sent a few of him to deliver the letter.

"What are the routes of your sentinels, point them out on the map."

"Yes, I waited for that day to be here on the order of Lord Lang, and here" The man stepped forward and stretched out his hand to point on the map while explaining the specific situation, Yu Wenwen looked at the map and fell into deep thought, Zhang Yu quietly pressed the knife with one hand to prevent an emergency from happening.

Fortunately, everything went smoothly and nothing abnormal happened, Yuwenwen clapped his hands and asked the soldiers guarding the door to come in and ordered: "Let Chen Tongjun come over." ”

"Also, prepare the ship immediately." ……

Xiyang City at night, a carriage under the escort of more than ten riders marched into the empty street, now it is curfew, so there are no pedestrians on the street, a patrol team that turned the street saw someone walking at night and greeted it, saw the lantern of the state government hanging in front of the carriage, and knew that this was the team of the yamen, but still stepped forward to ask.

According to the rules set by the envoy of Yuwen, no one was allowed to walk around the city during the curfew except for major events, and the patrol team must come forward to inquire about people walking on the street regardless of their identity, and if there is an urgent business to do, they must also register their names and what they are doing in case of subsequent inquiries.

If something happened in the city that night, these registered people were the first suspects, and they had to be interrogated by the state government at any time to eliminate suspicion, if anyone was found out by Yuwen Envoy, it was not a joke to walk around at night without anything, and it was much better to rely on this night security in Xiyang City.

"It turned out to be Yuwen Envoy!" The leader of the patrol team saw Zhang Yu's token and hurriedly saluted, now that the war in Jiangnan is tight, they know that Yuwen Envoy Jun is leading the troops to go out, but tonight the envoy Jun actually returned to the city, he was afraid that he would delay the important matter by stopping the car, Zhang Yu smiled and said that the envoy knew that you were working hard at night and dedicated to the public, so they would not take it to heart.

Everyone in the patrol team looked at the direction where the carriage was coming, it was the state ya, and the Yuwen envoy should have just returned from the state ya's errands, so they all got out of the way, and the carriage slowly drove forward, and they looked at the back of the team and talked about it.

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

"Who said it wasn't, the official army won one battle after another in Jiangnan, and Yuwen Envoy Jun is really capable of fighting!"

"I heard that those soldiers who participated in the war were rewarded for their meritorious service, and I knew that I would also be a soldier!"

"Come on, your virtue is still a soldier, don't go to the battlefield to pee your pants"

"You don't laugh at people"

A faint laugh came, Yuwen Wen, who was sitting in the car with his eyes closed, smiled, he received the emergency military information and immediately took a boat from Yanji in the south of the Yangtze River to the north and landed at Bakou, first went to the Hulin Army barracks, and then took a car into the city, and then after explaining important matters to Sima Yangji and Xu Shao on duty, he remembered that he still had a home in the city.

"I almost passed the door three times and didn't enter," he muttered to himself, all this time he was leading the troops either to beat Chen Jun or on the way to beat Chen Jun, and he almost forgot to go home to see after following a group of bachelors for a long time.

The carriage stopped in front of the Xiyang County Mansion, but Yu Wenwen did not get off, he saw that the night was deep, and he was worried that he would go back to the house and make too much noise, which would make the family members who should have fallen asleep get up again and be prone to cold, so let Zhang Yu go to explore first.

After a while, Zhang Yu led the housekeeper Li Sanjiu out, and Yu Wenwen heard Li Sanjiu's report that his wife and the two side ladies had fallen asleep, so he asked him to tell him tomorrow that he was all fine and did not need to worry.

"Is Lord Lang going back to his house to rest for the night? The small one makes people prepare hot water. Li Sanjiu asked.

"No, I still have important things to do, and everything in the house is as usual."

After a while, the carriage drove to the east of the city under the escort of the riders, and only then did Yu Wenwen enter the city from the east gate, because of the curfew, the east gate was closed, and they tossed for a long time to be able to successfully open the city gate.

The city gate slowly opened, and there was already a black pressure cavalry waiting outside the city for a long time, Yuwenwen got out of the car and walked out of the city, only to see a person coming up: "Lord Lang, I have already prepared!" ”

That person was Yuwen Fifteen, he led a horse to help Lord Lang ride up, Yuwen Wen looked back at the surrounding cavalry and immediately whipped his horse: "Everyone, come here tonight!" (To be continued.) )
