But when it was dawn, Xu Huang understood the secret of the Han army filling the trench overnight. He finally found that more than a dozen small stone walls appeared four steps away, and he guessed the reason.

It was very simple. The Han army dug more than a dozen tunnels at night, which went straight to the trenches, and the entrance was outside the range of the projector. Even if it was discovered by Cao's army, it could not attack the Han army. The Han army transported mud bags through the tunnels and filled two trenches overnight.

Xu Huang's guess was completely correct. This was Fazheng's authentic plan. He first dug a well in the camp, found the groundwater level, and then dug the authentic tunnels ten feet deep underground, and finally filled the trench.

As the trenches were filled, the Han army's attack was no longer hindered. Zhao Yun ordered generals Guan Xing and Zhang Bao to lead 10,000 troops to launch a full-scale attack on Hangu Pass.

The sun above Hangu Pass shot out thousands of golden lights. In the wilderness in front of the Han army camp, 20,000 Han troops were lined up, full of murderous intent, waiting for the order to attack.

In the team, huge nesting cars, ladders and box cars were launched at any time. On the top of the city, eight thousand Cao troops, fifty heavy catapults and five bed crossbows were also ready to fight. The two sides were tense and the battle was about to begin.

Zhao Yun waved his sword and shouted: "Strike!"

‘Dong!Dong!Dong!’

The fierce drum sounded suddenly, and 210,000 Han soldiers rushed towards Hangu Pass and rushed towards Hangu Pass, starting the Han army's full-scale siege.

Perhaps this is just the first attack, but it is definitely not a tentative attack, but a formal attack. During the years of war between the two armies of the Han army, they have long been familiar with each other's traps and no longer need to test.

The Han army had long known the Cao army's defense cover, which was far away from the catapult and crossbow, and the nearest was bow and arrow, and even the nearest was the rolling stone.

Especially the Han army had found news before that there were more than 10,000 defenders in Luoyang, which means that Cao's army would not defend Hangu Pass to death. If the defense of the city was not good, they would retreat to Luoyang.

It is precisely for this reason that the Han army went all out to attack from the beginning, and the Han army was full of morale. With the confidence of these 50,000 troops, they could concentrate their troops and conquer Cao's pass cities one by one.

At this time, news came from Chang'an that the 50,000 Han troops in Pujin Pass also began to attack the Cao army of Hedong County, and Shouchun also showed signs of attack.

In other words, the Han army had launched an attack on the Cao army from Bingzhou, Luoyang, Nanyang and Shouchun at the same time, which put a lot of pressure on Zhao Yun. He had to seize Hangu Pass as quickly as possible and force Cao's army into Luoyang. The key strategy of the Han army could be implemented.

It was the news from Chang'an that made Zhao Yun determined to seize Hangu Pass as quickly as possible at all costs.

Amid the rumbling drums of the attack, the Han army's 20,000 troops were divided into four square formations, advancing towards the frontier of the city. The number of people was dense. From a high place, the black Han army was densely packed, like an ant colony, covering the earth outside Hangu Pass.

"Advance!" Amid the drums, the Han general Zhang Bao shouted loudly.

"Kill!"

Amid the thunder-like shouts, the Han army advanced towards Hangu Pass like a tide. This time, the Han army used many siege weapons.

First there were the Chakra and the Cloud Ladder, which were the main weapons of the Han army's siege. These heavy weapons were dismantled and transported from Guanzhong, and then temporarily assembled. There were huge wooden wheels under the Chakra and the Cloud Ladder and were pushed forward by Han soldiers.

The second is the bucket chariot, which is a traditional defensive weapon for the Han army to resist the impact of huge rocks by catapults. The so-called bucket chariot is a rack made of thick wood, covered with several layers of cowhide, which is coated with thick grease, which is extremely smooth and has a certain oblique angle.

When a huge rock hits cowhide, it is easy to be lifted off. Although not every huge rock can defend against it, it can at least defend against 40% of the huge rocks.

A bucket is wide and five feet long. It is equipped with wooden wheels under it, which can be slowly pushed, while four Han soldiers are hidden below.

Amid the sound of war drums, the Han army's offensive formation advanced step by step. The nest chariot, skin fighting, cloud ladder and the vast Han army soldiers formed a spectacular black tide and rushed towards the city.

On the top of the city, Cao's army was ready. As many as fifty heavy trenchers were pulled open, and a ten-pound rock was placed in their leather pockets. Each trencher needed one person to pull it. Cao's army could not distribute so many troops, so they recruited thousands of civilians from various counties in Hongnong County to replenish the trenchers.

The Han army was getting closer and closer and had entered the four-step line. If it was a super-large catapult of two people, it could be projected, but the catapult at Hangu Pass was slightly smaller and the range was only long.

The general of Cao's army who was responsible for commanding the stone throwing machine was named Huo Ning, a fellow villager of Xu Huang. He followed Xu Huang for nearly twenty years and fought south and north, and was promoted to a captain step by step. During the Hefei war, he led his army to ambush Zhao Yan's army, which eventually led the Han army to suffer a crushing defeat in Lu'an County.

The chief general Xu Huang watched the Han army's attack wave approaching the city step by step. The front vanguard had reached four steps. Xu Huang issued a shooting order, first shot out the crossbow, and five four-foot-long iron arrows and countless dense arrows shot towards the Han army.

The Han army rushing in front of him was overturned, and several Han soldiers were shot down. The strong shooting tempted Huo Ning. He whispered to remind Xu Huang, "General, the fireball can be fired!"

But Xu Huang never let go, making the red flag in Huo Ning unable to wave it. If the red flag was not waved, fifty catapults commanders dared not give orders to shoot.

The Han army finally entered the range of the catapult. Xu Huang nodded, and the red flag in Huo Ning's hand finally waved, "Shoot!" Fifty Cao soldiers' commanders shouted almost at the same time.

The heavy trencher was launched, fifty long throwing poles swung out, smashing fifty huge stones into the Han army's formation. The huge stone made a sharp whistling sound, rolling in the air, and appeared rapidly above the Han army's heads. The Han army soldiers shouted, dodging to both sides, or hid behind the fighting cart.

With a muffled sound of 'boom!', the huge rock fell down, and dust flew. Several Han soldiers could not dodge and were smashed into meat sauce. The powerful impact force made the huge rock continue to roll and rushed straight into the group of Han soldiers. There was a scream immediately. More than a dozen soldiers were killed, blood splashed everywhere, and the entire huge rock was dyed red.

There was another loud noise, and a huge rock hit the truck. With a "bang", the smoothness on the cowhide made the angular rock unable to be solid. After sliding out for more than twenty steps, the huge rock did not achieve its effect.

But not every bucket car can withstand the impact of huge rocks, it depends on the smoothness of the stone itself. If the stone is rough and the edges are rough, it will be difficult for the fight to achieve the effect.

Another muffled sound, accompanied by the sound of the bracket breaking, a truck was smashed. Several Han soldiers hiding under the skin fighting stumbled out, and many people were injured by the collapsed wooden pillars and moaned in pain under the truck.

The second round of the trench was launched again, fifty huge rocks rolled in the air, roaring and smashing, causing the Han soldiers to overturn, flying flesh and blood, shattering the chariot, and the ladder to break, followed by the first round, the fourth round...

Several casualties occurred in each round of stone-capping. Although the stone-capping aircraft was extremely powerful, it was small after all and could not form huge lethality. More than 10,000 Han army troops had already rushed to the city. On the city, Cao's army fired thousands of arrows at the Han soldiers, and the arrows were like hail and rain, covering the sky and shooting at the Han soldiers.

Han soldiers raised their shields to greet them, and people were constantly killed by arrows. In the rain of arrows, thousands of Han soldiers pushed dozens of huge cloud ladders to the city wall, forming more than twenty siege points. Siege ladders several meters high were mounted on the top of the city, and groups of fierce Han soldiers rushed up the ladder and began to climb upwards.

Cao's army's arrows came in a slanted rain, and the wooden rocks were smashed head-on. A series of Han soldiers screamed and fell from the stairs. Their bodies were shot by arrows, and their heads were smashed. Under the city wall, corpses piled up like mountains. Then Han soldiers climbed up the stairs frantically and charged upwards regardless of everything.

At this time, the sound of drums in the Han army camp was heard again, and another five thousand Han archers rushed over, dust was flying. They passed through the range of the two steps to the steps of the huge rocks and crossbows at the fastest speed.

The huge rock roared and knocked the cavalry over. The crossbow arrows were powerful and fast. The iron arrows could shoot through the cavalry's bodies. The war horses were neighing, the soldiers rolled, and under the big rocks, there were terrible corpses and plasma everywhere.

At this moment, the Han army had invested 25,000 siege soldiers, and the city attack and defense battle entered the most intense stage.

...........

Unlike the Han army's bloody battle with Hangu Pass, the Han army's battle on the front line of Bingzhou was slightly easier. Last year, after the Han army conquered Lishi County and occupied the entire Xihe County, Cao's army was forced to strategically shrink in Bingzhou. Ten thousand troops stationed in Hedong County had to retreat east to Shangdang County, and connected with the original county, becoming the first western defense line in Yedu.

At this time, land and population are no longer so important, and building a defensive line against the Han army is the top priority. Hedong County and Yuan County are separated by Pingyang County and Shangdang County. Once the Han army marchs east from Xihe County, Yuan and Hedong will face the risk of being defeated one by one.

When the Cao army could no longer increase its troops, it could only shrink its defense line and concentrate 50,000 main forces of the Cao army on Shangdang County and the original county. As long as these two counties are guarded, it will be difficult for the Han army to break through the natural danger.

It was precisely for this reason that the Cao army actually gave up Hedong County and Pingyang County. When the general Guan Yu and military advisor Zhuge Liang led 50,000 Han troops from Pujin Pass to Hedong County, the 5,000 troops guarding Hedong County collapsed without fighting and quickly retreated to Shangdang County.

Guan Yu and Zhuge Liang did not continue to march northward, but consolidated their occupation of Hedong County. According to the strategic deployment of King Liu Jing of Han, Guan Yu ordered Guan Ping as a supporter. General Wu Lan and Leng Bao led 10,000 infantry and cavalry to advance eastward. The queen of heaven and the Han army captured Jiguan and Zhuguan in the Wangwu Mountains, and the army advanced into Henei County and rushed to Mengjindu in the southwest.
