However, when he arrived at Hangu Pass, Cao Liang was faintly disappointed, the dilapidated Guan Lou, almost half of the wall collapsed, and the old appearance of Hangu Pass could only be vaguely seen.

In the Han Dynasty, due to the rebuilding of the Han Hangu Pass, so the Qin Dynasty Guancheng gradually declined, to the end of the Han Dynasty, the role of the Hangu Pass was repeatedly weakened, and the newly built Tongguan completely replaced the status of the Hangu Pass, becoming a new upstart on the ancient road.

And Qinhan Valley Pass is already dilapidated because of disrepair.

Cao Liang boarded the Guancheng, looked back at the land of Guanluo, and couldn't help but sigh and sigh that the years were ruthless, four hundred years of vicissitudes have turned a majestic Guancheng into a pile of ruins.

The Yue Cavalry Battalion will stay overnight in Hangu Pass today, although it is said that the city wall has collapsed and the houses are gone, and the Yue Cavalry Battalion can only build tents by themselves.

However, the location of this fortress is extremely conducive to defense, even if the wall collapses, the Wei soldiers only need to build a few simple lines of defense to protect the entire army, and the security is many times stronger than those camps in the field.

Cao Liang didn't have any more requirements for today's camp, the reason why he wanted to camp in the dilapidated old gate building was to let them learn how to fight a good defensive battle in the city.

Although the strength of the Yue cavalry battalion is in the plains and fields, the cavalry is in a flat place, can be vertical and horizontal, invincible, but the real battlefield may not give you such an opportunity, just like the Xiao cavalry battalion in the Huainan War, it can fight in the field and defend the city, and it is completely an all-round army.

In the process of keeping up with the cavalry battalion, there are still many things worth learning, and this battle against Shu is undoubtedly the best opportunity to train the Yue cavalry.

After a day's trek, Cao Liang saw the city wall of Tongguan again under the reflection of the sunset.

Compared with the dilapidated Hangu Pass, the newly renovated Tongguan Pass is not the same.

The tall and majestic city wall, the majestic and mighty Guan Tower, Tongguan lies on the Guanluo official road, and if you want to break through such a dangerous pass, it is indeed a test to climb to the sky.

More importantly, now Tongguan has completely replaced the position of Hangu Pass, becoming the largest and last barrier in the Guanzhong Plain.

Since he arrived at Tongguan City, Cao Liang didn't plan to camp outside the city, so he decided to send someone to call for the city gate to be opened, and he would stay in Tongguan City tonight.

Yanghu and Du Yu accompanied this time, and Yanghu took the initiative to ask for help, and rushed forward to call the door.

When Yanghu arrived at the city of Tongguan with a few cavalry, it happened that the guards of Tongguan were closing the city gate, so Yanghu stepped forward and shouted loudly: "Please do not close the gate, the Yueqi battalion will arrive soon, and it will be difficult to open the city gate." ”

The soldier who was closing the city gate glanced at Yang Hu indifferently, his eyes were expressionless, but the movements of his hands did not stop at all, and with a "bang", the heavy city gate closed tightly.

Yanghu couldn't help frowning, could it be that the little soldier who closed the city gate was a deaf person, he was already shouting at the throat with his throat, and he didn't even pay attention to it, what a big boldness!

Now Yanghu's identity is to join the army as the general of Zhengxi and the governor of Yongliang, and the defenders of Tongguan are undoubtedly under the jurisdiction of the governor of Yongliang, and Yanghu, who has eaten a closed door, is slightly annoyed at the moment, but many years of knowledge and cultivation did not make him angry, he suppressed his anger and shouted at the gate tower in the city: "A certain is the general of Zhengxi to join the army Yanghu, let the generals who lead the army in your army come out to speak." ”

When the soldiers defending the city heard this, they were all shocked, and hurriedly reported to the Tongguan guard, the Tongguan Governor, Chengji.

The general of Zhengxi joined the army, and this hat was covered, how could they be provoked by these small soldiers, but Chengji, the governor of Tongguan, issued a death order, no matter who it was, no matter what happened, the city gate of Tongguan must be opened at sunrise and closed at sunset, and there must be no mistake.

These soldiers guarding the city naturally did not dare to disobey Chengji's orders, but they also couldn't provoke a big sheep, so they had to invite Chengji over.

Somehow, Chengji hasn't arrived for a long time, and Yanghu can't help but be annoyed, a small Tongguan guard, can actually put such a big score, it's just no one.

Cao Liang waited for a long time in the back, but there was no movement, so he urged the horse forward, came to the city, and saw that Yanghu did not call to open the city gate, and couldn't help but wonder if he said: "Uncle, why is the city gate not open?" ”

Yanghu said helplessly: "These soldiers guarding the city can't be the master, they don't dare to open the city gate, they have already sent someone to inform the guards in the city, I guess they are coming soon, right?" ”

It is customary to close the city gate at sunset, but when the army arrives, no matter how long it takes, the city gate will definitely be opened, otherwise the military situation will be delayed, and who can afford to bear the offense.

Cao Liang asked Yanghu: "Who is the guard of Tongguan now?" ”

Yanghu overheard the conversation of those guards guarding the city, and knew that the governor of Tongguan at this moment was Chengji, so he told Cao Liang.

"Chengji?" Cao Liang muttered to himself, no wonder no one dared to open the city gate, it turned out to be that brainless guy.

The reason why Cheng Ji left his name in history was that he personally killed the emperor of Wei, Cao Chao, and did an earth-shattering event.

When Cao Chao was in power, Sima Zhao held great power, and the climate of the Sima family's usurpation of the throne had become a success, and Cao Chao said angrily that Sima Zhao's heart was known to passers-by. Cao Chao, who was unwilling to be a puppet, led hundreds of palace people to crusade against Sima Zhao.

Originally, the hundreds of people led by Cao Chao had no combat effectiveness at all, and they would not pose a threat to Sima Zhao at all, but after all, the emperor's prestige was there, and Sima Zhao's cronies and Chinese troops retreated again and again, and they did not dare to confront them at all.

Only Cheng Ji, who was confused, obeyed Jia Chong's instigation, and stabbed Cao Chao to death, and finally Cheng Ji not only did not wait for meritorious service to be rewarded, but was killed by Sima Zhao and made a scapegoat.

Although it is said that when the Sima family was in charge, the imperial power was already dispensable, but where the emperor's shelf was, Cheng Ji lacked a string in his mind, so he would do the act of killing the king, and he thought that he could be promoted to the rank of official with such an opportunity, but in the end he was sent to the guillotine.

So Cao Liang was not surprised at all after hearing that the guard was Chengji, this guy was originally a pit goods, and it was completely expected that he would not open the city gate.
