Zhang Xuan came out of the Chinese army tent in Yun Dingxing, and just walked a few steps, but a black shadow blocked his way, and several pro-soldiers around him hurriedly drew their swords, Zhang Xuan drank the pro-soldiers, and he recognized the other party, it turned out to be Li Shimin.

"Is there something wrong with Li Gongzi looking for me?"

"Is the general going to attack the Turks?" Li Shimin asked.

Zhang Xuan smiled: "Does Li Gongzi have any suggestions?" ”

Li Shimin stepped forward and said: "In the battle of Guandu back then, Cao was weak and Yuan Qiang, but Cao Cao attacked Wuchao, causing Yuan Shao's army to run out of food and lose, I think the situation today is similar to Guandu, why didn't General Zhang sneak attack the Turkic logistics grain and grass land and force the Turks to withdraw their troops?" ”

Zhang Xuan secretly praised that this Li Shimin really lived up to his reputation, his eyes were sharp, and he saw the weakness of the Turkic army at a glance, Zhang Xuan smiled slightly: "I also have this consideration." ”

Li Shimin hurriedly said: "I am willing to follow the general to attack, and I beg the general for permission!" ”

"Your father's ............"

"There is no problem on my father's side, he usually just asks me, and in addition, I also want to bring my third brother Xuanba with me, so that he can also have a little practical experience."

Zhang Xuan smiled happily: "Let's set off tomorrow on the fifth watch, if the son can get up, just follow!" ”

Li Shimin bowed and saluted, "I will definitely come early!" ”

…………

Before dawn the next day, Zhang Xuan's 6,000 troops began to assemble rapidly, and Yun Dingxing was very efficient, and last night he allocated 5,000 war horses and prepared five days' dry food for each soldier, which was put in place overnight.

Zhang Xuan's army got up for breakfast at the fourth watch and became familiar with the war horses, Zhang Xuan ordered Wei Chi Gong and Pei Xingyan to be the vanguard, leading 1,000 cavalry to explore the road first, he and Li Jing led 5,000 troops to march behind, and Yang Shanhui stayed in Loufu Pass.

"General, Li Gongzi is here."

Jang Hyun turned his head. I saw Li Shimin walking quickly wearing armor, followed by his brother Li Xuanba, Li Xuanba still carried his drum urn, golden hammer, black helmet and black armor, and looked like a piece of black charcoal from a distance.

This time, Li Xuanba, the king of the north, behaved very low-key and followed his father all the time. If it weren't for Li Shimin to follow Zhang Xuan north this time, he wouldn't have shown up, but it could be seen that he was very excited, and his small eyes were shining.

Li Shimin went up and bowed, "Let the general wait for a long time." ”

Zhang Xuan nodded, "If Childe is ready, we will go." ”

"We're ready."

Zhang Xuan turned on his horse and shouted loudly: "Let's go!" ”

He rode his horse and rushed towards the outside of Loufu Pass, and the cavalry behind him was like a torrent. Follow Jang Hyun and gallop to the northwest.

Just an hour after Zhang Xuan traveled, Yun Dingxing led an army of 50,000 to leave Loufu Pass, and slowly traveled northward, pretending to enter Yanmen County eastward, he needed to contain the Turkic army for Zhang Xuan, and at the same time to cover up their intentions to go north for Zhang Xuan.

……………

Five thousand cavalry galloped through the vast canyon, flanked by cliffs and lush forests, a very hidden north-south road. It is 200 miles away from the Purple River Road where the Turkic army is moving south, and it is also more than 100 miles away from the Mayi Trade Road.

This road is called the Wolf Road. As the name suggests, it is the road taken by wolves, and wolves are infested all year round, even if dozens of people walk together, they dare not walk, so they are inaccessible all year round.

The 5,000 cavalry galloped north, and the sound of horses' hooves was like thunder. Rumbling in the valley, because Pei Xingyan's subordinates never came back to report the news, Zhang Xuan knew that the forward had not encountered danger in the north.

At this time, Li Shimin urged the horse to catch up with Zhang Xuan and asked in a low voice: "The general already knows the logistics of the Turkic army?" ”

Li Shimin found that the Sui army was extremely targeted. He vaguely guessed that Jang Hyun had already received the information.

Zhang Xuan smiled slightly, "Let's go to Yunnei County!" ”

Li Shimin was suddenly shocked, "That must be at the foot of Wuzhou Mountain." ”

"How does Childe know?"

"The food of the Turks must be millions of sheep, there is no place to raise sheep in Yungang County, but there is a large pasture under Wuzhou Mountain, which extends to the Sanggan River, and there can go directly south into Yanmen County, no need to detour to Shanyang County, less than hundreds of miles, which is very important for logistics and transportation."

Zhang Xuan smiled: "Childe is very familiar with Mayi County!" Been here before? ”

Li Shimin was a little embarrassed, "Don't hide it from the general, it's my first time here, but it took a lot of time to prepare before, even if I haven't been here, the terrain of Mayi County is already very familiar." ”

Li Shimin pointed to a big mountain in front of him, "In front is the White Wolf Mountain of Mayi County, which is east-west, dividing everything in Mayi County into two, stretching for thousands of miles, but there are more than a dozen mountain passes that can pass through the White Wolf Mountain, the most famous mountain pass is called the White Wolf Fortress, which is the only way for the trade road, about 80 miles east of us." ”

Zhang Xuan smiled and asked: "It seems that Li Gongzi is indeed very familiar with the terrain of Mayi County, so has Gongzi studied the road we took?" ”

Li Shimin thought for a while and said: "I have seen in the local chronicles of Mayi, there is a secret road through the mountain eighty miles west of the white wolf stopper, the valley is deep, the people are inaccessible, and there are wolves from time to time, so the name is the wolf road, which is a shortcut to Wuzhou Mountain!" ”

Li Jing laughed when he heard it, "Childe is right, three hundred miles through the White Wolf Mountain is Wuzhou Mountain, this is the nearest road to Wuzhou Mountain, however, how to go, it will not be written in the book, only those who have walked a few times will know." ”

"Sir has taught me well, he has traveled thousands of miles and read ten thousand books, and he warned me five years ago."

"You know?" Jang Hyun asked curiously.

Li Jing nodded, "I have taught the art of war in Wuchuan Mansion for a few years, and the second son seems to have come to listen to my class. ”

Zhang Xuan remembered that Li Jing was originally also an external doctor of Dou Qing, but he was cleared from the list of Wuchuan Mansions by Dugu, who paid attention to blood.

At this time, someone in front of me shouted: "I'm going to enter the hole!" ”

I saw the cavalry team turn their horses' heads to the west, leave the valley avenue, run onto a small road, and gallop towards a cave three zhang high and two zhang wide in the distance, Li Jing smiled and said: "Second son, this is the wolf's den, you didn't say it in your book!" ”

Li Shimin shook his head, "There is no record in the book, if I don't go once, I really don't know." ”

Everyone sped up their horses and ran towards the gloomy cave, which is a natural cave through the mountain, as long as more than ten miles, through this cave, the vast grassland suddenly appeared in front of them.......

Yunnei County, which is today's Datong, Shanxi, is located in the east of Wuzhou Mountain, and in the north is Baishan Mountain, where Liu Bang was surrounded by the Xiongnu army.

Two hundred years ago, after the establishment of the Northern Wei Dynasty, the Xianbei people set up the capital of Yunnei County, making Yunnei County the most prosperous capital in the north, and the famous Yungang Grottoes are under the Wuzhou Mountain in the west of Yungang County.

However, at any time when the Northern Wei Dynasty moved the capital to Luoyang and the passage of time, Yungang was gradually submerged by the dust of the years, the prosperity of the capital faded, the glorious buildings of the past became relics, and Yungang County also became an important town in the north of Mayi County.

Although Yunnei County is an important town in the north of Mayi County, the logistics center of the Turkic army this time is not in Yunnei County, but on the grassland about 50 miles southeast of Yunnei County, close to the middle reaches of the Sanggan River.

It was originally the refuge of the previous Turkic Khan in the Sui Dynasty, and it was here that Shibi Khan grew up, and he was extremely familiar with this area.

However, Shibi Khan set up a logistics base for his army here, not because it was his homeland, but because its strategic location was extremely important.

Since the Xiongnu era, Yunnei County is a strategic place for nomads to invade the Central Plains in the south, from here you can go south to the Mayi Road to enter the state, you can also go east along the Sanggan River to the military capital to enter Youzhou, and the cavalry can even take the Flying Fox Road into Hebei.

The southern attack of the Turkic army brought millions of sheep as military rations, and tens of thousands of sheep were continuously driven to Yanmen County every day to ensure the food security of the 300,000 Turkic army.

The grassland logistics base where the logistics center is located covers an area of about 5,000 acres, consisting of thousands of large tents and three sheepfolds covering an area of several hundred acres each, and 10,000 troops are stationed here to protect the security of the logistics center.

This is not only the important food area of the Turks, but also the storage place of their booty, this time the Turkic army marched south, plundered the three counties of Dingxiang, Yulin and Mayi, plundered countless cattle and sheep and tens of thousands of young women.

When they retreat, they will bring the plundered population back to the steppe, which is the tradition of the steppe nomads for thousands of years, and women are also their wealth, not only milking them and dressing them, but also giving them children and raising offspring.

Shibi Khan thought that the Sui army from Hebei might attack his logistics stronghold, so he deployed 20,000 heavy troops in the area of Lingqiu County, and deployed 8,000 cavalry in Yangyuan Town in the middle reaches of the Sanggan River, firmly targeting Wang Shichong's army from Shanggu County and Luo Yi's army from Zhuo County.

But Shibi Khan Khan could not have imagined that a brave Sui army would take the wolf road from the south to attack his logistics stronghold. (To be continued.) )
