"Fang Qi, send this letter to Xue Wanche! At the same time, send this to King Ren Cheng! After Lu Chen made up his mind, he sat directly at the table and worked hard to write, one was a letter to Xue Wanche, and the other was a legend of flying pigeons to Li Daozong.

"Yes!" Fang Qi solemnly took the letter and the flying pigeon biography handed to him by Lu Chen, carefully carried it into his arms, and then saluted Lu Chen and prepared to leave the camp.

"By the way, call Su Dingfang!" Lu Chen continued to look at the map, and at the same time ordered Fang Qi.

"Yes!" Fang Qi responded again, waited for a few more seconds, and after making sure that his grandfather had nothing else to order, he turned around and left the tent.

At tea time, the curtain of the camp tent was raised, and Su Dingfang walked in: "Grandpa, are you looking for a subordinate?" After Su Dingfang entered the camp tent, he saw Lu Chen looking at the map, so he asked in a low voice.

"It's coming!" Hearing Su Dingfang's voice, Lu Chen looked up at Su Dingfang, "Come here, help my public staff, where do you think the Turkic soldiers of Colum can be now?" Lu Chen beckoned directly to Su Dingfang, and motioned for Su Dingfang to come close to him and speak.

"Back to Grandpa, my subordinates really pondered it!" Hearing Lu Chen's words, Su Dingfang came to Lu Chen's side, stretched out his finger and pointed to two places on the map, "It is said that the news of the Turkic southward movement is accurate, but so far, except for the contact between the king of Rencheng and the Turkic cavalry, this Golun and the 20,000 Turkic cavalry have not moved, and the subordinates think that this Golun is waiting for the opportunity, and the closest place to Xicheng Pass are these two places!" ”

"Are there two counties of Mayi and San'in?" Looking at the two areas that Su Dingfang was referring to, Lu Chen muttered, "Why do you say that?" Lu Chen looked at Su Dingfang and asked.

"Back then, his subordinates followed Liu Heimin, and tens of millions of Turks in these two places asked for help!" Su Dingfang said very directly, "This Mayi is a plain land, which is most suitable for cavalry battles, while this Shanyin is the opposite of Mayi, where there are many mountain ranges, which are most suitable for troops to hide in!" Su Dingfang explained, "Moreover, these two places are now under the control of Liang Shidu, and they are the two closest places to Xicheng Pass!" After Su Dingfang finished speaking, he quietly waited for his grandfather to speak.

After listening to Su Dingfang's analysis, Lu Chen nodded unconsciously, Ma Yi This place Lu Chen also understood, it is located in the upper reaches of the Sanggan River, bordering the Inner Mongolia Plain, and the south is Yanmen Pass, if the cavalry charges, it can be said that this place is the most suitable area north of Xicheng Pass.

Shanyin County is a place in the semi-mountainous area and half a plain, which is the difference between it and Mayi, and this place is the Hengshan branch Cuiwei Mountain in the southeast, and the Hongtao Mountain in the northwest, the terrain of Shanyin County itself is somewhat low-lying, it can be said that it is easy to defend and difficult to attack, and the mountains on both sides are the best places to ambush.

Similar to Mayi, Sanyin County is also quite close to Xichengguan.

"Lao Su, if you were Golun, where would you choose to set up camp in these two places?" Lu Chen touched his chin and looked at Su Dingfang and asked with a smile.

"If the subordinate is Colum, I will choose this place!" As Lu Chen finished asking, Su Dingfang directly pointed to another place and replied with a smile.

"Ying County?" Lu Chen glanced at the location that Su Dingfang was pointing to, "Why are you here?" Lu Chen asked with some surprise, you know, this place in Yingxian County is an important place in Sanchong, and if you really want to set up the barracks here, isn't it a live target?

"Dangerous moves!" Su Dingfang said with a smile, "It is said that this is an important place for Sanchong, but this is also a place where you can attack and retreat, you can retreat to Shanyin to the west, you can directly enter Heng Mountain to the east, and face the Xicheng Pass to the south. Su Dingfang smiled very confidently.

"That's what you can think!" Lu Chen glanced at Su Dingfang and said with a smile, "Then Gelun doesn't have you these two times!" Send a message to the Lady Army and ask them to send scouts to San'in and Mayi to have a look! Lu Chen threw the red and blue pencils on the map and said to Su Dingfang.

"Yes!" After Su Dingfang saluted, he turned around and left the camp directly.

"You should be like everyone else, and you can destroy the Three Kingdoms alone! Capture the king alive! Looking at the back of Su Dingfang's departure, Lu Chen muttered in a voice that only he could hear, if Golun had Su Dingfang, the Turks would have already entered the customs and gone south!

"Lord, there's news from Grandpa!" Behind Li Daozong, who was standing on the city tower and looking north, there was the sound of eager footsteps, followed by a guard to Li Daozong's side, whispered, and at the same time took out the flying pigeon from Lu Chen's bosom.

"Oh?" Li Daozong, who was still a little anxious, was in a much better mood after hearing the report from the guards, and since he passed the news to Lu Chen yesterday, Li Daozong didn't sleep well this night, and climbed to the city tower early this morning, and used the monocular given to him by Lu Chen to look at the large camp of the Turkic soldiers thirty miles away.

Li Daozong directly snatched the bamboo tube in the guard's hand, opened the seal, took out the note and looked at it, and then directly put the note into the sleeve cage, and the guard on the side carefully peeked at the expression of his prince.

Since Yuan Junzhang came to Lingzhou with 10,000 Turkic cavalry, his prince's face has not been good-looking, this guard has also followed Li Daozong to fight in the south and north for several years, and he has never found that his prince's face is so ugly, when he claimed to be 100,000 Turkic cavalry went south and attacked Lingzhou, his own prince has never been worried, why is it that the face of the prince of 10,000 Turkic cavalry is so ugly?

Although he wondered in his heart, no one dared to touch the moldy head of this prince, and his face looked as if someone else owed him eight hundred hangings.

But now after Li Daozong read the small note, it was obvious that his prince was in a much better mood, and his face was soothed, and the guard couldn't help but breathe a sigh of relief.

"Why aren't these bunnies attacking the city yet?" Li Daozong continued to look at the Turkic military camp in the distance with a monocular, and couldn't help but curse.

"Whew~!" Hearing his own prince scolding, the guards on the side were even more relaxed.

"Lord Wang, Manager Yang is here!" Just after the guards breathed a sigh of relief, there were footsteps on the side, and the guards glanced back, hurriedly saluted the visitor, and then reported to Li Daozong in a low voice.
