A heavy snow fluttered down, covering the vast wilderness of Hebei, making the Great Plain of Hebei a snow-capped world.

Leshou County in the south of Hejian County, which is the capital of Dou Jiande, is also covered by the vast snow, and in the early morning, there is no figure in the snowy world.

At this time, two black dots appeared in the distance, getting closer and closer, it was two soldiers on horseback, two horsemen on horseback through the snow with difficulty, and came to the city gate, at this time the city gate had been opened, and the two cavalry rushed into the city, and ran towards Dou Jiande's palace, Jincheng Palace.

In the imperial study of Jincheng Palace, two pots of coals are burning, making the room exceptionally warm, Dou Jiande is discussing with the strategist Song Zhengben about the countermeasures of Hebei Province, since the defeat of Hanoi County, Dou Jiande is deeply afraid of Yang Yuanqing, he knows that Yang Yuanqing will attack Hebei sooner or later, he has been worrying about spending these months, so that the minister has repeatedly asked him to build a dynasty to ascend the throne, he has no intention to respond.

Dou Jiande considered during this time that he wanted to leave a way back for himself, if his army could defeat the Northern Sui army, it would be good, but if he could not defeat the Sui army, then at least he had a place to retreat.

Dou Jiande considered Qingzhou Xu Yuanlang, this person occupied the four counties of Qingzhou, such as Donglai, Beihai, Gaomi and Qi County, which was originally Li Mi's territory, but after being occupied by Xu Yuanlang, Li Mi didn't seem to have much reaction, which made Dou Jiande regret it, he was originally fighting the idea of Qingzhou, but he was worried about turning his face with Li Mi, so he didn't do it for a long time, but Xu Yuanlang was stunned After Qing occupied the four counties of Qingzhou, Li Mi actually acquiesced. This made Dou Jiande very annoyed, and he knew that he would do it first.

However, Dou Jiande also knew that Xu Yuanlang was originally a general of the Wagang Army, and he occupied the four counties of Qingzhou, maybe Li Mi still regarded him as the force of the Wagang Army, so he didn't care, if it was himself, it would be completely different.

But in any case, Dou Jiande has already decided to seize the four counties of Qingzhou. Leaving a way back for himself, he was ready to take the opportunity to marry Xu Yuanlang's sister as a concubine and annex the four counties of Qingzhou.

Dou Jiande stood in front of the window with his hands in his hands, and said worriedly: "Xu Yuanlang only has 20,000 troops under him, so don't worry, I'm still worried about Li Mi, if I annex Xu Yuanlang, I will annoy Li Mi." He led the army to attack Qingzhou, and Yang Yuanqing came to attack Hebei, so that I suffered from the enemy, originally I hoped that Li Mi could assist me to jointly resist the Sui army's eastward expedition, I was worried that the mutton was not eaten, but caused a commotion. ”

Song Zhengben smiled slightly: "The lord wants to count on Li Mi to help resist Yang Yuanqing's Eastern Expedition, but his subordinates feel that it is unrealistic. ”

"Why?" Dou Jiande asked puzzled.

"Have you forgotten? Li Mi had already surrendered to Luoyang and proclaimed himself Sui Chen. ”

Dou Jiande shook his head: "His surrender is not sincere at all. It's purely to fish in troubled waters, seize Luoyang, and then coerce the Son of Heaven to order the princes, don't take that matter to heart. ”

"But whether he is sincere or not, he will at least do a good job on the surface, denounce us as traitors, and more importantly, Yang Yuanqing's expedition to the east did not hurt his interests, he has no intention of helping us at all, but it is difficult to refuse because of the previous alliance agreement, but he surrendered to the Sui Dynasty. Then he found an excuse, since he is a Sui minister, how can he help us again, the lord said, isn't it? ”

Dou Jiande pondered for a long time, and sighed softly: "You are right, if a man like Li Mi has no interests. Will he help us in vain? It's just that if I seize the four counties of Qingzhou, will Li Mi be annoyed and angry? Instead, they will attack me when Yang Yuanqing is advancing eastward, and that's what I'm worried about. ”

"My lord. It depends on Yu Wenhua's performance, if he can hold Li Mi back, then there is no problem. ”

"Yu Culture and!"

Dou Jiande muttered to himself, and suddenly sneered, "That idiot, can he hold Li Mi back?" ”

"Lord, although Yu Wenhua is incompetent, his general Chen Ling is very powerful and should not be underestimated."

"I also hope that he can hold Li Mi back."

Dou Jiande sighed, looked at a messenger who rushed on the field, and said lightly: "It should be the news of Yu Wenhua." ”

Soon, someone outside the door reported, "Lord Wang, there is information from the south." ”

"Come in!"

Dou Jiande gave Song Zhengben a look, Song Zhengben also sat down, and a messenger walked in quickly, knelt down on one knee and said: "Report to the prince, Li Mi's 200,000 army and Yu Wenhua and the army have been facing each other in Pengcheng County for almost a month. ”

"As expected."

Dou Jiande laughed, he waved his hand, and ordered the messenger to go down, he said to Song Zhengben with some excitement: "Our opportunity has come!" ”

Song Zhengben also smiled: "It is estimated that Yu Wenhua is going north by boat, and the Yellow River is frozen, making it difficult for him to go north, so he can only stay in Pengcheng County, the 100,000 troops in his hands are all regular troops of the Sui Dynasty, and their combat effectiveness is very strong, Li Mi may not be able to easily eliminate him, at least the confrontation situation will not be broken until February next year, and the lord can use this opportunity to take Xu Yuanlang." ”

Dou Jiande couldn't hold back the excitement in his heart, and immediately ordered: "Pass my order, I want to go south to marry the new princess!" ”

…………，

Just when the vast snow covered the land of Hebei, Yanmen County was also icy and snowy, and the east of Yanmen County was the focus of the Sui army's defense, and there were two strategic routes into Hebei, one was the military capital, and the other was the Flying Fox.

The two strategic roads are with the help of the river channel that crosses the Taihang Mountain, the former is the Sangganshui, and the latter is the easy water, the difference is that the easy water is only one of the sections, from Feihu County to Yi County you can go to the Yishui River Valley, and from Lingqiu County to Feihu County this section has to cross the mountains and valleys, the road is very difficult.

Cheng Biting Jin galloped and rushed to Lingqiu County in two days, but what he didn't expect was that only half a day later, Yang Yuanqing also rushed to Lingqiu County, and attacking Yi County was a big deal, and he was still a little worried about Cheng Biting Jin.

Yang Yuanqing's entire strategic plan was to take two steps, the first step was for him to find a foothold in Hebei to establish a logistics base, and then the second step was to launch a spring offensive.

On this foothold, Yang Yuanqing chose Shanggu County, he had attacked Wang Bashu of Shanggu County in the winter of the seventh year of the Great Cause, and he was very familiar with the situation of winter warfare here.

Yanmen County has a total of 20,000 garrisons, the main general is Qin Qiong, Qin Qiong is currently the general of the Zuo Xiao cavalry guard, and there are two generals under him, one Niu Jinda, the other is Cheng Yanjin, of which Niu Jinda led 5,000 troops to garrison the Anbian Military Fort in the north, and Luo Yi's Youzhou Army confronted, while Qin Qiong and Cheng Yanjin led 15,000 troops to be stationed in Lingqiu County, waiting for the order to attack Hebei.

The Sui army camp is not in Lingqiu County, but at the mouth of the Feihu Gorge in the southeast of the county, there is a river here, and the Sui army camp is stationed in a wilderness on the west bank of the river.

Yang Yuanqing took Qin Qiong and Cheng Yanjin and more than 100 personal soldiers to the Baishui River, in the distance is the entrance of the Flying Fox with terrain like a trumpet, on both sides are gentle hills, covered with dense forests, the hills increase from west to east, the highest place is the Mangmang Taihang Mountain, and there is also a section of the Great Wall of Qin that has been abandoned on the mountain.

"Did you see it?"

Yang Yuanqing pointed to a narrow open space on the opposite bank, and said to Qin Qiong: "In the fourth year of Renshou, I led eighteen generals and more than 100 subordinates, and it was there that more than 1,000 people who defeated Yang Liang's army, more than ten years have passed in a flash, and it still looks like what happened yesterday when I think about it, I was full of spirit at that time, and it is really nostalgic to think about it!" ”

Qin Qiong was thinking about the task given to him by Yang Yuanqing, seizing Feihu County and Yi County, Yang Yuanqing's sigh did not resonate with him, but Cheng Biting Jin next to him sighed: "Now the manager is also in high spirits!" Talking and laughing, Wei Dao'er, no! Dou Jiande fell apart. ”

Yang Yuanqing smiled slightly, turned back to Cheng Yanjin and said: "I heard Xu Shiji say that your strategy to win the Tiger Prison is very good, making full use of the weakness of men who are greedy for women, this time I hope you will make another surprise attack to capture Feihu County." ”

"But ......"

Cheng Biting Jin was so cold that he shivered, "On such a cold day, I can't stand it anymore to pretend to be a woman naked." ”

"You don't have to pretend to be a woman, you can think of other ways, if you take Feihu County, I will reward you with three thousand taels of silver to make up for your losses, how about it?" Yang Yuanqing looked at him with encouragement.

Cheng Yanjin thought about what such a cold man likes the most? He rolled his eyes, and suddenly there was a way.

"Chief, is there a village in the Flying Fox?"

"Yes! There is a village with about 100 families who make a living from hunting. ”

"Then you can give it a try!"

"Good!"

Yang Yuanqing smiled approvingly at Qin Qiong: "Let Lao Cheng fight Feihu County, General Qin will take Yi County, and I will wait for your good news in Lingqiu County." ”

…………

Feihu County is a small county, less than 1,000 households, located in the west of Taihang Mountain, the intersection of Heng Mountain and Yan Mountain, is the birthplace of Laishui and Yishui, the geographical location is very important, here is also a transit station of Feihu Road, from here you can directly walk the Yishui River Valley, after walking more than 200 miles to the east, you can reach Yi County, the county seat is built on a hill, the city is as strong as a fortress, easy to defend and difficult to attack.

For the Sui army, if you want to take Shanggu County, Feihu County is the first unavoidable bridgehead, Feihu County is also the west gate of Shanggu County, as long as Feihu County is taken, the gate of Shanggu County will be opened, you can enter the Yishui River Valley, and go straight to the hinterland of Shanggu County, because Feihu County is small, it can't accommodate too many soldiers, and there are only 2,000 garrisons of Wei Dao'er, led by Wei Dao'er's nephew Wei Tiesheng.

At this time, Feihu County has been closed by heavy snow, the deepest snow is waist-high, unless there is enough manpower to remove snow, it is very difficult to come from Feihu Road, plus the time for the Sui army to attack Hebei is next spring, whether it is to go to Jingcheng or Feihu is not necessarily, so the defense of Feihu County is not strict, it is almost evening, and there are only sparse dozens of defenders on the city.

At this time, there was a melodious camel bell in the distance, and some defenders found that a team of camels came from the distance and came from the Flying Fox Road, which surprised the defenders that someone could actually walk through the Flying Fox Road covered by heavy snow.
