Hangu Pass has been regarded as one since ancient times

The most fundamental reason for "the first pass in the world" lies in its extremely special terrain: it is stuck in the continuous mountains of Shaanxi Mo Mountain and Kushan Mountain, and it is not in the mountain pass, but two or three miles after the entrance of the canyon; If you enter the city, it is deep and long

"Han" of the canyon. Later generations of "Water Jing Note" cloud: "The north goes out of the east, and it is commonly known as Hangu Pass." The sky is high on the shore, the empty valley is deep, the gorge of the stream, the car is not square, and the number is dangerous...... The rock is dangerous and solid, and the belt is easy to keep. "If it is just such a long valley sandwiched between two hills, or a detour, it is not difficult for a soldier to do so.

However, it is the Kunshan Mountain, the Taolin Heights and the three major plateaus of Shaanxi and Mo are entangled and entangled in the mountains, with a radius of nearly thousands of miles.

Just the Kuafu Mountain in the peach forest highlands is

"Three hundred miles wide". The Shaanxi Mo mountain plateau in the north of Hangu Pass is even more high and continuous, the big river rushes in the meantime, the two banks are stacked on top of each other, and the highest one is open

"Fang Liyu, three sides of the wall, high thousands of miles." Surrounded by such mountains, vast forests, and inaccessible to people, it has become an insurmountable vast natural danger between the Central Plains and Guanzhong.

If you want to enter Guanzhong from the western part of the Central Plains, there is only one passage through Hangu Pass. Since King Wu Keshang, the Great Zhou Dynasty attached great importance to the Guancheng city connecting the Central Plains and the hinterland of Guanzhong, and the successive emperors have greatly repaired it.

In addition to the use of long stone bars to build fortresses, a more significant improvement is that the walls of Guancheng were stretched out for about five or six miles to the mountains on both sides, becoming a small Great Wall with Guancheng as the axis.

At the top of the Great Wall at both ends, two beacon towers were set up, but there was an enemy situation, and the lonely two pillars of wolf smoke went straight to the sky on the top of the mountain.

On the Great Wall, the female wall battlements are connected with the stone city wall, and the arrow holes are dense and solid; Every three feet, there is a neatly arranged hill - all of coarse and smooth rolling logs and stones of various shapes and sizes; Every five zhang, there is a strong crossbow fixed to a huge wooden frame, and there is a stone house dedicated to storing long-range arrows; Between the hill and the stone house, there is a continuous array of weapons.

But in the event of a war, in addition to the weapons in the hands of the soldiers, the weapon racks are also filled with all kinds of weapons in hand, and there will never be a situation where the sword cuts the ground and has nowhere to change.

In order to ensure that Hangu Pass was foolproof, King Xiao of Zhou specially moved 500 old Zhou families around the military camp in Guancheng.

These 500 families either farmed or hunted, did not pay any taxes to the government, and only did two things a year: one month to make stone and one month to make wood.

Stone making is the process of digging hard rock and polishing it into stone chips of various shapes and sizes.

The so-called wood making is to cut down dead trees in the mountains, cut the thickest middle section of the trunk, and make two sharp and thick rolling logs in the middle.

In every battle, 500 families immediately gathered, and the able-bodied formed a team of porters, and the old, weak, women, and children cooked rice for the army.

Only 10,000 infantry were stationed at Hangu Pass on weekdays, but with the support of this long-term and carefully constructed defensive barrier, it was impregnable.

When going out to explore the enemy, Wei He inspected the defense of Hangu Pass in detail, and at the end he only asked Chongli: "Once the Chu army attacks the city, can it support it for three days?" Chongli pondered for a moment, and then arched his hand and said: "Report to the Hou: There is no rescue outside, Chongli is enough to support the ten-day!" Wei He waved his hand: "Okay!" The outnumbered do not increase their troops. But if you get out of the wolf smoke, you will start fighting. Supporting it for three days is a great achievement. "Looking at the city today, Chongli knows that this is an unprecedented fierce battle.

But according to the pre-plan, he divided the 10,000 armor soldiers into two shifts to meet the enemy, with 5,000 per shift, and rotated every two hours.

Because there is a large wall of more than ten miles at both ends of the city, there are 1,000 guerrillas in each class.

The Chu army attacked the city, and it was the main force of the Chinese army led by Xiong Zhi, the son of Xiong Hong, who attacked in the center. It is facing the Guancheng Arrow Tower standing in the middle of the valley of the two mountains, and the avenue outside the city and the gentle slope on the side of the road are all one or two miles wide.

This is the axis of Hangu Pass and the main direction of the siege. Xiong Zhi is young and vigorous, but also the first to seize the first merit, in the past few days carefully planned: a pair of ladders for 100 people, a cloud car for 1,000 people, a total of 100 ladders and 10 cloud cars, strong thick hemp rope and iron hooks, machetes, axes and other siege equipment, but also repeatedly checked and correct.

An even more powerful hand is that Xiong Zhi concentrated 3,000 strong bows and crossbowmen from the follow-up army that could not directly attack the city, and wanted to completely suppress the arrow rain at Hangu Pass.

At this moment, the horn was together, and Xiong Zhi roared: "Release the arrow!" The three thousand strong bows and crossbows in formation fired in unison, and a dense rain of arrows poured down violently towards the arrow tower and the city wall in a scream.

For a time, the arrow tower wall of Hangu Pass was flooded by the rain of arrows, and it was so hazy that it almost disappeared from between the canyons.

At this time, the war drums were raised, and fifty hundred-man teams hugged the cloud ladder and pushed the cloud car mountain to rush to the city wall like a tsunami.

As long as the ladder rests on the city wall, the cloud chariot is pulled up under the city, and the rain of arrows under the city stops pouring, the siege battle will enter hand-to-hand combat, and nine times out of ten it will be completed.

Seeing that the cloud ladder roared against the city wall, the cloud chariot also stood tall, and the city climbers had already stepped on the cloud chariot wooden ladder, and there was no movement in the city.

Zhou Jun scared away? Is Hangu Pass an empty city? Still is...... Xiong's obsession flashed, and he suddenly remembered what his father had mentioned, and laughed: "Stop shooting!" Hangu Pass is an empty city......" The words did not fall, suddenly the drum of the city head was loud and loud, as if the heavy thunder pressed the top, and the dense boulders rumbled down along the slope of the city wall, and the waves continued one after another.

Under the slamming boulder of the cloud ladder and the cloud wheel, it was crushed and crushed in an instant.

At the same time, a dense rain of arrows was shot from the arrow holes all over the women's wall, and the soldiers who were only trying to avoid the boulders made live arrow targets, and one by one they were bloodily inserted in the cracks of the big rocks, unable to move half a step.

Within a few moments, the first group of 5,000 soldiers had lost most of their lives and wounded. Xiong Zhi's face was pale, and he wanted to shout, but he couldn't shout in a daze.

Holding back for a moment, he pointed at Guan Cheng and scolded hatefully: "Chongli, you two-faced traitor, this prince will definitely skin you alive!" He turned around and jumped to his feet and roared: "The second formation is again!" If you can't take Hangu Pass, give me death! "Besides, Chu Ling Yin Qizhao, who was responsible for capturing the wall, was facing a rugged mountain with lush trees and strange rocks, standing at the bottom of the mountain, he could only see the banner and wolf smoke on the Great Wall of Hangu Pass in the distance, not to mention the onslaught, it was even more difficult to climb to the foot of the Great Wall.

Qi Zhao looked at the boulder on the hillside for a moment, looked at the direction of the wind, gritted his teeth and shouted: "Burn - burn these mountains and forests, and step out of a road!" ”
