(Thank you for the monthly ticket support of the two children's shoes on the banks of the Yongle River, thank you.) ）

Everything was as Chen Kefu predicted, Song Jingang and Zhen Zhai'er each led their troops and horses, and carried the people of Dingxiang and Mayi counties outside Yanmen Pass all the way, entrusting their families to lead their mouths, and burning villages and cities along the way, filling wells, and polluting rivers. Only about half of this brigade of men and horses had entered Yanmen Pass, and when most of them were still outside the pass, Qin Qiong, who was ordered by Chen Kefu to lead a light horse to reconnoiter in the area of Dingxiang Grassland, had already sent back a special letter from the Flying Eagle.

The soldiers and horses of the Turkic Khan Yehu have crossed the border of the steppe, and a vanguard iron cavalry has entered Dingxiang County. Its vanguard troops had already occupied the county town of Dali, which was already an empty city at this time, and after receiving the warning signal, all the generals gathered at Yanmen Pass understood that the Turkic people's southward movement was indeed obvious.

Dali County is the only city in Dingxiang County, in the early years of the Great Cause, Dingxiang as the border between the Great Sui and the Eastern Turks, there were few people. And after the Eastern Turkic Shibi Khan at the end of the Great Cause, Dingxiang became more and more desolate. Up to now, Dingxiang has basically become a no-man's land between the Central Plains and the grassland. But although Dingxiang is like a huge no-man's land, Dingxiang has always been a territory belonging to the Central Plains. Now that the Turkic iron cavalry has suddenly invaded the county town of Dali, the meaning of this is self-evident.

The Turks invaded Dali County, and the next step would be Mayi City, and the next step would be Yanmen Pass. Chen Kefu knew that the time was pressing, and took the generals to the city to inspect the city defense, and after many days of preparation, the news that Chen Kefu was coming to Yanmen Pass had not yet been revealed. The soldiers and horses of the imperial court have been mobilized one after another, and now 80,000 male soldiers have gathered under the Yanmen Pass, in addition to 50,000 township soldiers and 50,000 militia groups urgently summoned by the local people in Hedong, defending the city and fighting, and the defending side has a natural advantage. Even those who are not well equipped enough. Township soldiers and militia groups whose soldiers are not elite enough can also play a huge role.

Standing on the wall of Yanmen Pass, which had been re-heightened and reinforced, Chen Kefu looked at the cannon covered by a red robe on the gate of the city, and sighed with emotion. The Central Plains Dynasty for hundreds of years. The greatest problem always comes from the grassland, and the aggressiveness of the nomads towards the farming peoples of the Central Plains can never be changed. At that time, Yang Guang was also a very discerning king, but in the end, he was severely injured by the grassland people under this Yanmen Pass. In the end, I returned depressed.

Now, after only a few years, the Turks have attacked again, and compared to the last time, this time the Tongyehu Khan is an unprecedentedly powerful steppe leader who basically unified the entire Turkic Khanate. Back then, an Eastern Turk almost captured Yang Guang, but now for the first time after the unification of the Eastern and Western Turks, Chen Kefu understands how much pressure he has on him.

It was not that there were no courtiers who advised him to temporarily avoid the sharp edge of the Turks, and even many people, like Li Jing, proposed to be friendly to the Turks like the Han Dynasty. Delay the army, wait until the unification of the Central Plains in the future, and then compete with the Turks.

Chen Kefu thought about it for a long time. In the end, he refused to avoid it. The current Tongye Hu Khan is only afraid that he is more energetic than the original Shibi Khan. Confidence. Concession at this time will only be regarded as weakness and bullying.

Looking at the peaks of Gozhu Mountain. Chen Kefu sighed: "The situation in Hedong is the most solid. Outside the Guanzhong, I will be the first to reach the east of the river. Gaiyu its east, then too act of the barrier, its west, then the river for its belt, in the north, the desert, Yin Mountain for the outer shelter, and Gouzhu, Yanmen for the internal risk, in the south, then the first yang, the bottom pillar, the city, the Wangwu mountains riverside and the wrong confrontation, and the south is Mengjin, Tongguan are my gateway. If Fen and Hun linger on the right, and Zhang and Qin are enveloped on the left, then the original Xi can be perfused, and the Cao Su can be transferred. And the husband is more in Jin, Bolongmen, then Jing Wei can be folded down; Out of the patio, under the pot pass, Handan, the well to the east, can I only do what I want? Therefore, the situation of the world must be taken from Hedong. ”…,

Li Jing nodded and said, "What Your Majesty said is extremely true, Hedong is the hub of the entire north. This status of Hedong is due to its high terrain overlooking three sides between Guanzhong, Henan and Hebei. Outside the east of the river, there are Taihang Mountain, Luliang Mountain, Wangwu, Xicheng, Zhongtiao and other mountains to form its outer barrier, and there is the Yellow River in the west; There are Heng Mountain, Wutai Mountain, Guanshui Mountain, Zhoushan Mountain, Taiyue Mountain, Yunzhong Mountain, Huo Mountain, Jiwang Mountain and other mountains are staggered, constituting its inner circle danger; Rivers such as the Fen River, the Zhanghe River, the Hutuo River, and the Sanggan River flow in different directions. The rivers alluvium between the mountains, forming a series of bead-like basins. ”

"Taihang Bacheng is an important passage between Hedong and Hebei and Henan. In the west of Hedong, there are Guanshui Mountain, Luliang Mountain and other mountains and mountains, and in the southwest, there is Pujin, the crossing of the Yellow River, which is the only way to travel between Hedong and Guanzhong. The situation of mountains and rivers in Hedong has made Hedong an extremely favorable position for internal operations. If the situation is favorable, you can attack from three sides, and if you are unfavorable, you can defend against danger. The situation of mountains and rivers in the east of the river is not only the most important pass for us to guard against the grassland tribes, but also the most important breakthrough point for the grassland tribes to move south. ”

The old handsome Wang Ren Gongjiu Town Hedong, can be said to be very familiar with every grass and tree in Hedong. At this time, he was also worried: "It is precisely because the Turks understand the importance of Hedong that they send troops to invade Hedong. The old minister thought that His Majesty retreated to Yanmen and guarded the pass, although the strategy of defense and counterattack was stable. However, there are still some places where we have to think in advance, and we are guarding Yanmen, although we can prevent the Turks from continuing to move south, and prevent the Turks from taking the opportunity to attack Luoyang, the capital division. However, in this way, we also completely abandoned the two counties of Mayi and Dingxiang outside Yanmen. Dingxiang is already remote, and it is not important to give up. However, there are Yunnei, Shenwu, Shanyang, Mayi, Heng'an and other important towns on the first line of Mayi, and there are dangerous passes such as the Great Wall. ”

Moreover, Yunnei Town has always been an important military town, and its place is located between Guanshui Mountain, Heng Mountain and the south side of the grassland. The low mountain mouth to the north provided a convenient passage for the influx of Turks; The Sanggan River originates from Guanshui Mountain, flows into Hebei through the basins of Yunnei and Heng'an. In this way, once the Turkic iron cavalry entered Yunnei, they could enter Hebei along the lowlands of the Sanggan River valley to the east, and knock in front of the military capital; You can also pass the Taihang Mountain from the Flying Fox Pass and detour to the southwest side of Beijing. Beijing, as the capital of Dachen, may be invaded by the Turks at any time. At the beginning of the Western Han Dynasty, Mao Dun Shan Yu immediately led the Hun army to pour in, and Liu Bang, the ancestor of the Han Dynasty, climbed the mountain in Pingcheng Baishan, which is now the Baishan Mountain in Heng'an Town, Yunnei. Your Majesty, the old minister thought. It is certainly the best policy to defend according to the wild goose gate. But we can't easily give up the towns of Mayi, Shenwu, Yunnei, and Heng'an. The old minister was incompetent, and he was willing to ask for orders to lead the troops to the towns of Mayi, and resist the southward movement of the Turkic iron cavalry according to the city. ”

Wang Rengong said very sincerely. Of course, Chen Kefu also understood the meaning of his words. The real frontier pass between Hedong and the grassland people should indeed be in the towns of Mayi, and Yanmen is just the last pass for the grassland iron cavalry to pour into the hinterland of the Central Plains.

In fact, as Wang Rengong said. The area of Dingxiang is actually just a no-man's-land separation zone between the Central Plains and the grassland people, and there are not many people living in it since ancient times. Since the Han Dynasty, the Xiongnu, Xianbei, Rouran, and today's Turks have all invaded the basin in this area of Yunnei several times, so as to invade Hedong or Hebei.

Chen Kefu, who is familiar with history, knows very well that in the early Western Han Dynasty. Mao Dunshan Yu immediately led the Xiongnu army to pour in, besieged the Han Gaozu Liu Bang in Pingcheng Bai Mountain. At the beginning of the Han Dynasty, the Xiongnu were recuperated and recuperated, and strategic defense was carried out against the Xiongnu in the north. He used to garrison troops here. It connects Yuyang and Shanggu in the east, and Yunzhong and Wuyuan in the west. Protect the North.

The Eastern Han Dynasty declined, and the land of the north gradually became deserted. Nomads from outside the Saiwai poured into the Datong Basin and penetrated into the east of the river. During the "Yongjia Rebellion", Liu Kun, the pastor of the Western Jin Dynasty and the state, in order to fight against the Huns Liu Yuan, invited troops to Tuoba Lu, the leader of the Xianbei Tuoba Tribe. Tuoba Yilu was named the acting king with merit. After Tuoba Yilu, he asked Liu Kun for the land of Daibei, and built the capital in Pingcheng. The Tuoba Department grew stronger and stronger. During the Sixteen Kingdoms, although the country established by the Tuoba Department was once destroyed by the Former Qin, after the collapse of the Former Qin, Tuoba Jue soon restored the country and established the Northern Wei Dynasty. The Northern Wei Dynasty established the capital of Pingcheng, based on the Daibei, destroyed the Houyan of Hebei in the east, the Northern Yan of Liaodong, Helianxia in the Xiping Pass, the Beiliang of Hexi, swept Rouran in the north, and seized the land of the south of the Liu Song River in the south, and unified the north. …,

After that, it was the Turks who dominated the north. The Turks also repeatedly invaded this area. The Northern Qi, Northern Zhou, Sui, and now Dachen all suffered greatly from it, and the pressure on the defense of the north was very great.

Chen Kefu now plans to abandon the first line of Daibei Mayi and gather troops and horses to defend Yanmen Pass, which is the first of the nine fortresses in the world, and this plan is indeed a wise move. But in this way, it is equivalent to giving up the first line of Daibei Mayi, and the Turks can directly attack Yanmen without much effort. Wang Rengong, as an old handsome, naturally saw the benefits of such an arrangement to the Turks, and they would have no worries and go all the way down to Yanmen.

He proposed to lead troops to defend the towns of Mayi and resist step by step, which was actually a good military strategy, which could delay the southward movement of the Turkic iron hooves and win more time for the imperial court to mobilize troops and horses. Second, it can also be used to consume the Turks' soldiers and horses, retreat step by step, and form a huge echelon defense from Mayi to Yanmen, winning more depth for the defenders. Even Wang Rengong could continue to stay in the Daibei area after the loss of the Mayi Zhucheng to threaten the Turkic logistics supply lines and threaten their rear routes.

This is a very good proposition, but at the same time it is a very dangerous one. Yanmen now has a limited number of soldiers and horses, even if Chen Kefu really gives Wang Rengong 350,000 soldiers and horses, he can go out of the customs alone, facing hundreds of thousands of iron horsemen of the Turks, they are still the possibility of nine deaths.

Looking at the gray-haired old handsome Wang Rengong, he couldn't help but be moved by the courage of his soldiers. Knowing that the future is difficult and dangerous, but still fearless, this is the real wind of bravery. Chen Kefu stepped forward and hugged Wang Rengong heavily, and said gratefully: "I gave Lao Shuai 50,000 light horses, but I don't want Wang Shuai to go to the cities of Mayi and Yunnei to hold on. As long as you stay in Daibei, then even if the Turks go south, they will inevitably have to leave a lot of troops to deal with you, and they will not dare to go south with all their might. As long as the old commander restrains some of the Turkic forces in the back and attacks them once or twice at the right time, I believe that this will already be the best result. ”

Wang Rengong heard Chen Kefu's confession and understood that the emperor was worried about the safety of the soldiers, and changed the resistance of the city to guerrilla warfare, which was much less effective against the Turks, but the soldiers avoided the end of certain death. At this moment, in the face of the emperor's concern, he felt more and more that this trip was a heavy responsibility.

ps: Muzi I'm back again, I was sick some time ago, and the tragedy was interrupted for several days. I'm starting to resume the update today, sorry!
