Tongguan, the earliest time was only as a spare tire of Hangu Pass, in the Qin Dynasty when a little repair, for the Qin Dynasty's imperial system, more important is Hangu Pass, but in the Guangwu Emperor period, Tongguan as a defense against the Xiqiang rebellion affected the importance of the Guanzhong gradually reflected, so it was gradually repaired.

However, after all, the land of Sanfu still belongs to the territory of the Han Dynasty, and this kind of pass within the Han Empire has not received much tilt in materials, so it is not as majestic and dangerous as the Tongguan in later generations.

In ancient warfare, the terrain of the pass was simply a nightmare for the attackers.

Even if Tongguan does not have a perfect city defense now, it is like an insurmountable moat, resisting the offensive of Huangfu Song's organization wave after wave.

It's just that Hu Zhen's defense is not easy.

After all, Huangfu Song is a battle-hardened general, commanding the army that was put together temporarily, and he didn't see a little chaos and obstacles at all.

With Huangfu Song leading these trained soldiers in Hedong as the backbone, and Yang Biao, the head of Hongnong, to agitate, the potential hidden in the depths of Hongnong was quickly tapped, from Yiyang, from Luhun, from Luxian, from Xincheng, from Quanwu and other places, teams of soldiers gathered, groups of people were organized, and one by one the baggage trucks were driven out and gathered here in Tongguan and gathered in Huxian.

Some people are more lucky, responsible for transporting grain and grass, although it is harder, doing cattle and horses to carry it, but at least they don't have to be like the people here in Tongguan, being conscripted, under the blade of the supervising team, stumbling and crying to use soil, and even use their own lives to fill the trench under Tongguan......

Huangfu Song commanded very calmly, and the surrounding soldiers did not have any objections. In their opinion, this thing itself is coolie, what's wrong with letting these people do it? You can't let the soldiers go up and do this kind of thing, can you? It is only right that good steel should be used on the edge of the knife.

However, it is naturally impossible for the Xiliang soldiers led by the defending Hu Zhen to watch the trench being filled, even if they have mercy, otherwise they will be killing themselves, so under the large number of bows and arrows, these people are unobstructed, and they are wounded layer by layer, falling, dying, and rolling in the trench with the soil.

Some of the people who fell into the trench, wounded but not dead for the time being, with the wounds pierced by arrows, with the wounds drawn by the sharp antlers at the bottom of the trench, wailing in pain and rolling in despair.

At both ends of the trench, whether it was Huangfu Song or Hu Zhen, they all watched all this indifferently, without the slightest emotional fluctuation, and the flesh and blood stained in the trench seemed to be completely non-existent.

The siege and siege of cities in this era are all like this.

Huangfu Song still has some bottom line, after the ditch was filled, he waved his hand to let Minzhuang retreat, and did not hold Minzhuang to continue to use his flesh and blood to smear the city wall of Tongguan, and use Minzhuang's life to consume the equipment to defend the city, although this kind of thing is also the most common thing in this era when attacking the city.

After all, this is still Hongnong, and this degree still needs to be grasped.

Behind Huangfu Song, dozens of leather drums beat earth-shatteringly, and the dull drum sound was like a sound in the human body, stirring the heart and pumping the blood together with the drum sound, making people's blood swell.

This Tongguan must be captured as soon as possible!

Huangfu Song sat on top of a pimaza, with a solemn expression on his face, his gray beard fluttering in the wind, his eyes staring at Tongguan, his fingers pinching something, as if he was constantly calculating how to fight, how many lives to fill in, in order to conquer this Tongguan!

In the sound of the golden drum, a team of soldiers rushed forward with equipment, in the command one by one, accompanied by the crazy fighting of the two sides, accompanied by the meat of both sides flying sideways, accompanied by the destruction of the siege equipment and the defense system of the city wall, at this node, Tongguan is like a flesh and blood grinding plate, the people and soldiers who are unfortunately involved in it, all stirred up a mess, and smeared their flesh and blood on the city and under the city.

And behind the Huangfu Song infantry battle array, there was a team of Hu cavalry.

These Southern Huns, who followed Huangfu Song all the way from Gaonu, did not have much interest in Tongguan or anything, and they did not pay much attention to how Huangfu Song attacked the city, because they knew that there was nothing to do with them.

For these Southern Huns, listening to the orders of Huangfu Song or obeying the orders of Hongnong Yang is not much different from obeying the orders of Pingyang, the Hun Zhonglang, the important thing is how much loot you can take back, how much property you can bring to your family, this is the most important issue.

For Huangfu Song, it is very important to attack Xiatong Pass as soon as possible.

From Hongnong into the pass, one is along the Tongguan line of the big river, the other is from Luxian bypass, over the mountains and mountains to take the Wuguan line, and then break the pass out of Lantian, then enter the pass.

The second road is not that it cannot be walked, but once the army enters the mountain, this time is not calculated in days, and it will take tens or even months to move, and between the mountain roads, the grain and grass are not convenient to transport, the difference between them, how can Huangfu Song, who is experienced in the combat command army, not know the difference?

Therefore, it is better to gnaw down Tongguan than to take the mountain road!

What's more, Tongguan is not as good as Hangu Pass, whether it is the city wall or the garrison, it is more than one grade worse, so although there is some loss of human life, it will definitely be able to fill it!

And you can't give the Xiliang thieves a chance to breathe, although Huangfu Song's army is also a hasty army, and the queue may be more flexible if it is repaired, but the longer Huangfu Song spends in Hongnong, it is equivalent to giving the Xiliang soldiers more time to prepare, and at a pass like Tongguan, the Xiliang soldiers are prepared a little more, maybe Huangfu Song and they will have to use ten of their lives to fill the ......

Huangfu Song looked up at the sky and said, "Another wave!" ”

"Yui!"

The herald said yes loudly, and then under the drums and flags, another wave of soldiers swarmed towards Tongguan......

Then, under the frantic resistance of the Xiliang soldiers above Tongguan, they had to retreat again.

Huangfu Song finally stood up from Piza and said, "...... That's it today...... Mingjin Recruits ......"

As soon as the order to collect the troops came out, the soldiers who were lining up couldn't help but exhale a long breath.

It's finally been a day.

Merely......

What about tomorrow?

Or how many days can you survive?

At this point, the soldiers on both sides have no bottom in their hearts......
