Early in the morning, the temperature inside and outside Yizhou City was a little low, and in the military tent of the martial arts students, after a busy night, the sand table had been made.

The soldiers in the barracks have slowly woken up, the martial arts students are resting in the military tent at the moment, and Cao Can and Li Jilong are going to the camp tent to report the situation last night, at this moment, suddenly a white figure descended from the sky and landed on a pigeon cage, with a letter bag tied to its leg.

Cao Can took the letter from the pigeon's lap and read it, and soon after he went to Li Jilong with the letter.

Li Jilong squinted his eyes and was about to go back to the camp to rest, when he suddenly saw Cao Can's face coming excitedly, and at this moment he wondered: "What's wrong with Brother Cao, are you happy about the sand table?" ”

"Nope." Cao Can took out the secret letter from his cuff and handed it to Li Jilong, "You can take a look." ”

"Seems to be a good thing." Li Jilong said in his heart, sure enough, this secret letter came from Feihu, "I didn't expect him to successfully penetrate into the Liao army." ”

In the Yizhou military camp, Emperor Zhao Kuangyin just woke up from his sleep, last night he has been holding the book that records various tactics of war and browsing, and asked Zhang Dejun on the side, only then did he know that the compiler of this book has a stroke of his son Zhao Dezhao, Zhao Kuangyin took this book, and his heart was full of emotion, I don't know what it tasted like.

Because of thinking about the war situation in the north, Zhao Kuangyin woke up naturally early in the morning, and then he caught a glimpse of the light outside, and suddenly a person came in directly outside the military tent, only to see Zhang Dejun immediately announced: "Official, Brother Fang Cai'er sent a letter saying that the sand table has been made, please move the official family to see it." ”

"Oh, so fast?" Zhao Kuangyin felt a little incredible, he suddenly got up from the bed, and then instructed Zhang Dejun, "Zhang Daguan, you let Cao Bin and Pan Mei come to the Chinese military camp at noon today for the next marching plan. ”

"Yes." Zhang Dejun retreated.

After noon, the weather was a little warm, the south wind was blowing around, the fiery red Song army flag fluttered in the sky, and Cao Bin and others also hurried to the big tent of the Chinese army.

In the big tent, the emperor Zhao Kuangyin was sitting in a precarious position, he was dressed ordinary, only wearing a thick round-necked robe, and the rest of the generals sat separately as soon as they entered the military tent, and after a while, Zhao Kuangyin ordered to go down in person, and then there were twelve or thirteen young generals carrying a huge sand table into the military tent.

Zhao Kuangyin took a quick look at the huge sand table, although he hadn't seen the details above, but he said in his heart: This is the result of overnight, it seems that it took a lot of hard work and hard work of these martial arts students, Cao Can and Li Jilong They really lived up to my expectations.

Cao Bin, Pan Mei and others also turned their heads and looked at the huge sand table that the young generals had assembled and assembled, which were marked with some place names and passes, city walls, mountains, rivers and other locations, and the two were a little dumbfounded.

Cao Bin raised his head, stared at everything on the sand table with wide eyes, he suddenly thought that Cao Can's wild boy had always been mysterious, he originally thought that it would take a day or two to make a pair of sand tables, but now it took a night of work to come out, it seems that Cao Can and they are tired enough to work this night.

Zhao Kuangyin got up from his seat, and then quickly walked to the spliced sand table, "This is the Flying Fox, it's really a Xiongguan." If our Song army can capture this place, the future battle situation will be opened, and the northern border defense of our Great Song Dynasty will be safer. ”

This time, the sand table is mainly based on the terrain around the Flying Fox Pass, and I saw that the whole mountain made on the sand table is undulating and stretching, and Zhao Kuangyin also knows that this mountain range is hundreds of miles long from books such as geography.

The role of the sand table is once again highlighted, it vividly expresses all the information, Zhao Kuangyin's hand has pointed to a narrow valley that stretches for hundreds of miles, this valley is marked as "Flying Fox". The so-called "陉" character is the place where the valley is interrupted, and the topography here just says it all.

Zhao Kuangyin once learned in the "Chronicles of the Expedition" that there are eight mountains in Taihang, which are used from south to north as Yiguan, Taihang, Bai, Fukou, Jing, Feihu, Puyin and Jundu. These eight paths are guarded in this Taihang Mountain, and even if it is an enemy army, it cannot enter and exit at will.

If it weren't for Shi Jingjiao's ceded these passes in the northern Xinjiang, the Great Song Dynasty would not have been threatened by the Liao State trapped in the north, and the Liao army could also go south from here at any time to attack Yizhou, Huazhou and other places.

Zhao Kuangyin thought for a moment, he knew that the flying fox has always been in the name of precipitous, and this place is also an important passage in and out of Youzhou and Jizhou, as early as the first year of Tianfu in the Jin Dynasty with Ulzhou fell into Liao, and it has been in the hands of the Liao people for 20 years.

"This is the result of their hard work all night?" Cao Bin said to Pan Mei on the side.

Pan Mei whispered in Cao Bin's ear: "Yes, this morning when Weiqing and Weigu came to my tent, they happily told me, I only know a little about it, but I am also curious, they actually spent one night to drum it up, if it is placed in normal times, this will take a few more days." ”

"What Brother Pan said?" Cao Bin seemed to have some doubts, his eyes kept looking at Pan Mei, and after a while, he seemed to understand something, and then said, "If it is really as Brother Pan thinks, then Xiao Siwen's tent will not be very stable." ”

Pan Mei stroked a little short beard under her cheeks, and then lowered her voice and said, "That's naturally the case, and it's just my guess at the moment." ”

"That kid has been hiding it from me." Cao Bin smiled bitterly, and then continued to turn his gaze to the sand table, while Emperor Zhao Kuangyin's eyes were wrinkled.

Zhao Kuangyin has been thinking with low eyebrows, the position of the Flying Fox is too important for Song Jun, now the sand table has been formed, he leaned down, his eyes have always been near the Flying Fox, Zhao Kuangyin closed his eyes, and the location of the Flying Fox has been flashing in his mind, and the surrounding mountains and mountains are also flashing in his mind.

Flying Fox is a canyon that is more than 100 miles long, the valley on both sides is like a blade scabbard, this place is easy to defend and difficult to attack, it has always been a place where soldiers must fight, and this place runs through the north and south, most of it falls in the hands of the Liao army at present, if the Song army wants to solve the worries, it must be snatched from the hands of the Liao army, and the Liao army will be driven out of this range.

At this moment, Zhao Kuangyin's heart had already flown to the Flying Fox, and he pointed to the Flying Fox on the sand table and said: "Everyone, if the Liao army is allowed to guard the Flying Fox all the time, my Song army will be like giving up its back to the enemy, and the enemy will also harass me in the north unscrupulously. During the Spring and Autumn Period and the Warring States Period, the State of Qi invaded Jin, entered Mengmen, and ascended to Taihang; The Qin State invaded Han, broke the danger of sheep intestines, and captured Xingyang in one fell swoop; When Chu and Han were fighting for power, Liu Bang was trapped between Xingyang and Chenggao, and Li Shiqi suggested that he strangle the mouth of the flying fox in the north and guard the white horse in the south......"

When the rest of the generals heard this, they also frowned, the Flying Fox was very important to them, but for now they had to find out the whereabouts of the Liao army near the Flying Fox, and then make sure that they would talk about it.

Zhao Kuangyin then summoned Cao Can and Li Jilong, two young generals, into the military tent. At present, what Zhao Kuangyin needs most is military intelligence, and after he asked the essence of fighting in the mountains and forests yesterday, he has been thinking about it in his mind last night, and after reading the war method again, Zhao Kuangyin's heart agreed to this method.

Cao Can and Li Jilong had not slept all night, and had only rested in the tent for two hours this morning, and now that the emperor had summoned them, they naturally felt sincerely afraid.

Zhao Kuangyin brought up the old story again, and asked as soon as he opened his mouth: "After I took the book back, I read it all night, and as for the battle in the mountains and forests, I think it is very wonderful." If Brother Can'er and Batu, your martial arts students, participate in the war, how sure are you? ”

Cao Can and Li Jilong said: "Official, if we want to do it, we used to have three or four points, but now I feel that there are seven or eight points. ”

At this moment, Cao Bin suddenly said: "Can'er is messing around, fighting is not a child's play." ”

Zhao Kuangyin turned his head, he understood what Cao Bin meant, and he smiled: "Brother Cao, don't be like this, just let Brother Can'er finish his words." ”

Cao Can glanced at Cao Bin, he knew the meaning of his father's words, he was afraid that he would be young and impulsive, and he would say big things in front of the official family, since ancient times, fighting a war has not been a child's play, at this moment he said calmly: "Official, this morning we and other martial arts students received a secret letter from the flying fox, and I already know a little bit about the details of the enemy army." ”

"Oh?" Zhao Kuangyin and they said in unison.

"What's going on?" Zhao Kuangyin asked.

"That's the ......" Then Cao Can told Zhao Kuangyin about the situation in the Flying Fox Mountain, Zhao Kuangyin was a little convinced, and read the content of the letter again, knowing what Cao Can and they had been doing recently.

"Ling Tu is actually in the Flying Fox Clan, how come I don't know, haven't I gone with the scouts to find out the news these days?" Zhao Kuangyin heard Cao Can talk about He Lingtu, and he was also very shocked, and said at this moment.

"The official family didn't know, Ling Tu met a Liao army in the mountains, they went all the way to the Flying Fox, Ling Tu was afraid that someone would find his traces, so he pretended to be a Khitan soldier and mixed in with the enemy, as for the other scouts have been waiting in the mountains, waiting for an attack, forming a combination of inside and outside."

Zhao Kuangyin nodded, and said: "That's good, now that Lingtu is in the tent of the Liao army, this can provide a lot of military information for my Song army, and our army also knows itself and knows the enemy, and there are fewer mistakes. ”

After the Liao army withdrew from Jinpo Pass, the Song army sent 10,000 troops to garrison Jinpo Pass, and at the same time they also advanced the battle line to this place, forming a confrontation with the enemy.

Ps. It should be a flying fox, not a flying fox shin, and there was a mistake in the previous article.
