Tongguan front line.

The central tent of the Left Army was staggered on the northern foot of Qilin Mountain, beside the Yellow River. Deng Ai's flag of the character "Ship" fluttered high, as if he was afraid that people would not know his existence.

The camps in the Central Army tent have always been criticized because the northern foot of Qilin Mountain is close to the Yellow River, and there is a natural chasm behind the Yuanwanggou. Not to mention the small area, it is too close to the front line of Tongguan. If you climb to the city of Tongguan, you can see the place without any danger. Once the Jin army launches a sneak attack, it will be difficult for the Central Army to deal with it.

Deng Ai disagreed with this. In fact, he deliberately set up the central army tent here, with the purpose of luring the Jin army guarding the city out to attack. Deng Ai had long ambushed an elite soldier on Qilin Mountain. As long as the Jin army dared to leave the customs, he would have no return.

However, with the current situation of the Jin army, I'm afraid they don't have the courage to come out of the pass to attack. The current general guarding Tongguan is Hu Fen. Although Hu Fen is not a famous general, he is still relatively stable in terms of preservation. This is also the reason why Sima Lun valued Hu Fen. In fact, guarding such a key barrier like Tongguan does not require much high level or ability. The more wise and brave the famous generals have more ideas, and they always consider how to win a surprise.

The more mediocre generals often do not have the courage. They will focus on keeping steady. As long as they can defend Tongguan, they will be the greatest success. As for other ideas, they really don’t.

Hu Fen is a typical general of this type. He does not seek merit, but does not seek any mistakes. Before going to Tongguan, he received Sima Lun's face-to-face teaching opportunity. In fact, Sima Lun's request is very simple, that is, Hu Fen should make good use of the dangerous terrain of Tongguan, focus on steady defense, and not be greedy for merit and seek victory. He is the first achievement. If he loses Tongguan, he will come to see him.

So after arriving at Tongguan, Hu Fen put the steadily guarding Tongguan first. What's more, he fought with the Bingzhou army many times and was defeated repeatedly, and he was indeed afraid of being beaten. If he had fought in the plains, Hu Fen really didn't take on this job, but fortunately, with such a steep pass as Tongguan to help, it would have added some courage to Hu Fen.

Tongguan is adjacent to the Yellow River in the north and the Qinling Mountains in the south. This city of Guancheng is located on the narrow passage between the mountains and rivers, guarding the Guanluo Avenue from Luoyang to Chang'an. It is surrounded by mountains and waters, and it is dangerously bound to the sky. It controls the Qinling Mountains in the south and wind Lingdu in the north. It is the necessary road that cannot be avoided from Luoyang to Chang'an.

In fact, Tongguan and Hangu Pass are on the same line, one is the west entrance and the other is the east entrance. Hangu Pass is closer to Luoyang, while Tongguan is closer to Chang'an.

During the Qin Dynasty, Hangu Pass was the most important reason. The main reason was that Qin State was more offensive. Hangu Pass became a springboard for Qin State to attack the six eastern countries. It can attack and retreat and defend. Even if the six countries jointly attacked Qin State, when facing Hangu Pass, they were still sighing and unable to enter.

However, from the perspective of pure defense in Guanzhong, Hangu Pass is not as good as Tongguan. After all, the strategic position of Hangu Pass is too forward, and there are hundreds of miles of supply lines behind him, which will undoubtedly increase the defense cost of Hangu Pass.

Tongguan is at the end of the Wuhan Pass and is close to Chang'an. It is easy to use both supply and reinforcement. Therefore, after Qin, the strategic value of Tongguan was highlighted, and Hangu Pass was abandoned, and Tongguan became the most important part of Guanzhong's defense system.

The reason why the Sima family gave up the capital Luoyang and moved the capital to Guanzhong was that fortresses like Wuguan in Tongguan could help them resist the Bingzhou army's powerful troops. From the collapse of the Yellow River defense line after it was broken, it can be seen that the Sima family's army no longer had the ability to compete with the Bingzhou army without any danger. If they continue to defend Luoyang, the Sima family might have given it in Luoyang.

Therefore, retreating to Guanzhong and moving the capital to Chang'an was the last choice for the Sima family to be unable to force them. The defense line built by Tongguan Wuguan and Pubanjin has also become their last barrier. Only by defending such passes such as Tongguan can the Sima family survive.

Hu Fen performed his duties conscientiously. After arriving at Tongguan, he set up a strict defense, prepared for the war seriously, and actively built the defense line of Tongguan, showing his extraordinary efforts. After all, Hu Fen was a loyal member of the Sima family and had a grudge against the Bingzhou army to kill his father, so Hu Fen could not surrender to Cao Liang's power. He and the Sima family were grasshoppers tied to a rope. They prospered and lost. While working for the Sima family, they also contributed to their future.

When Deng Ai led the army to come, Hu Fen was facing a great enemy and transferred all his troops to the key pass and carried out strict defenses on Tongguan.

Unexpectedly, Deng Ai actually set up the Central Army's Commander Camp at the foot of Qilin Mountain, which is only five or six miles away from the Guancheng in Tongguan. Standing on the Guanlou, the Bingzhou Army's camp was unobstructed.

Deng Ai's move also angered many Sima Army generals, thinking that Deng Ai was really arrogant, which was clearly a bully of the Sima Army and did not dare to go out of seclusion. So he asked Hu Fen to fight, hoping to lead an army to fight in the middle of the night, attack the Bingzhou Army's commander camp, and give Deng Ai a warning.

But Hu Fen sneered. This was clearly Deng Ai's trap. He was hoping that Sima's army would attack him out of the city. If he sent troops out of the city at this moment and hit Deng Ai's plan, no matter how many people he sent out, he would probably go but not return.

Hu Fen knew very well what kind of person Deng Ai was. After all, they were old opponents who had been fighting for many years. Hu Fen could not suffer more than once under Deng Ai's hands. Therefore, when Hu Fen faced Deng Ai, he really had no capital to underestimate the enemy, but instead attached great importance to it.

Deng Ai set up camp at the foot of Qilin Mountain, as if he had deliberately dug a big pit for Hu Fen, preparing to jump inside. However, Hu Fen was deceived and naturally would not jump into the pit anymore. So this time he was determined and ordered that no matter what the situation occurred, the troops and horses of each battalion would not be allowed to leave the gate, and those who violated the order would be executed immediately without mercy.

This order naturally dispelled the idea of ​​many generals. Even if they were unwilling to accept it, the military order was as good as a mountain, and no one dared to disobey it.

Deng Ai saw that Hu Fen was not fooled or cared. He had no hope of luring the enemy out of the city. When he met a steady general like Hu Fen, the possibility of luring the enemy was only lower. Therefore, if he wanted to win Tongguan, he still had a hard power. After the troops of each battalion arrived, Deng Ai launched a comprehensive attack on Tongguan, trying to use his strength to knock on the door in the switch.
