Tongguan City is not directly adjacent to the Yellow River, but is between a towering wasteland mountain range.

Hu Yanyan and others led the Huns' troops out of the city one after another, first walked north along the Forbidden Gully to the avenue next to the Yellow River embankment, and then headed west.

As long as you continue to advance for a while, cross the intersection of the Wei River and the Yellow River, you can directly walk to the Guanzhong Plain of Yima Pingchuan.

Hu Yanyan turned around and looked at Tongguan with a blazing flames, and his nervous mood eased a little.

The fire-driven objects in the city have blocked the roads. Even if the Han army noticed it and put out the fire, it would not work without a day.

Now they only need to rush through the Han army in front to intercept them and return to Chang'an.

"General, it's not good!"

Just as Hu Yanyan was thinking about this, a Hun general who was exploring the way forward rushed over.

The general looked panicked, and it was obvious that he had encountered an urgent military situation.

"What's the matter?"

"General, on the road ahead, Qingzhou thieves built a big city!"

"Big City?" Hu Yanyan was shocked when he heard this.

The road ahead is the only way. If the Han army built a city on the road, it would be impossible for the Huns to break quickly if there were 18,000 people who died.

However, in just a few days, how could the thieves in Qingzhou build a city?

Hu Yanyan immediately asked, "Did you read it wrong?"

"General, you must be wrong. I can see clearly that it is a big city. Although the city wall is not very high, it firmly controls the official road!"

"It's impossible. In just a few days, how could the thief build a city!" Hu Yanyan suddenly fell into panic.

It is now a biting winter with a biting wind, and the soil in the construction is very hard. It is very difficult to transport bricks and stones. It is absolutely impossible to build a city so quickly.

"You can see clearly what the thief's city looks like?" Hu Yanyan asked.

"The thief's ranger is very fierce. The general did not dare to go too far, but that city is definitely not wrong."

"Let's go ahead and lead the way. I'm going to see it myself!"

After Hu Yanyan said that, he led everyone to speed ahead.

When Hu Yanyan arrived on the avenue, a long wall about one meter tall appeared in front of him.

Faced with the fiercely powerful Hun cavalry, the Han cavalry, with a disadvantaged number, retreated one after another.

Hu Yanyan and others were able to check again.

After seeing this, Hu Yanyan's heart completely cooled down.

"It's really a city!"

Hu Yanyan was very frightened to see a simple city standing across the avenue.

The exterior wall of the city is in a crisscrossing shape, firmly occupying a great avenue.

"This city wall is actually made of ice!"

The Hun generals beside him exclaimed in unison.

Because the city wall in front of me emitted the luster of ice crystals, the Han army poured river water on the city wall, turning the originally weak city wall into a solid ice layer.

"The thief is going to cut off our life!" Hu Yanyan couldn't help but feel sad.

The simple city in front of us is neither tall nor majestic, but for the Huns who were eager to escape, even if they spent an extra quarter of an hour in the battle, there was an extra danger of being surrounded by the main force of the Han army.

"General, are we sending troops to attack?" A Hun general asked worriedly.

Hu Yanyan did not answer, but he raised his eyes to look around.

To the north of this avenue is the icy Yellow River, which has gradually begun to appear. Going along the northwest, it is the Wei River that flows into it.

On the south side, there is a dense area of ​​mountains and valleys. Although it is barely accessible, it will definitely cause heavy losses.

What's more, after walking around these steep and difficult mountains, the Han army was very likely to continue to intercept them with ease.

However, if you really make up your mind to attack the city, you don’t know if you can solve these obstacles before the Han army pursues them.

Hu Yanyan didn’t know the specific deployment of the Han army behind this ‘Ice City’.

When everyone saw Hu Yanyan not speaking, they all knew that it was already extremely critical at this time.

Suddenly, Hu Yanyan discovered a passable location from the south side.

At that location, the Han army did not build an ice city. Although the roads were a bit rugged, it was better than the mountains and hills further south.

"You guys see where!"

Hu Yanyan stretched out his hand and pointed to that place, and everyone stretched their necks to look at it.

"General, it's OK to pass there, but it's too close to the thief. If you are intercepted while passing, it's extremely dangerous!" A Hun general said worriedly.

"I can't care about that much anymore. This is the only way. General, let's rush over from there!" Another Hun general said loudly.

The situation is urgent at this time. If everyone stays still, they will definitely be waiting to die.

Rather than doing this, it would be better to rush over directly.

"Cunning, it's so cunning!" Hu Yanyan said gritting his teeth.

"I see that the terrain is narrow. If it is intercepted by the thief army in the middle, there will be no power to fight back."

"But if we don't walk from there, we will be trapped here again."

After hearing Hu Yanyan's words, everyone frowned and said nothing.

It is obvious that in Hu Yanyan's words, they had already noticed the intentions of the Qingzhou thieves.

They just wanted to let the Hun army pass through the narrow passage in the south, and then "hit halfway through", so that the Hun army would completely collapse.

"In that case, many men will be left behind." said an older Hun general.

"Anyway, people will die. No matter how they die, they will die!" Hu Yanyan said helplessly.

Even if they suffered a great defeat, at least Hu Yanyan and others had a glimmer of hope.

On the "Ice City" in front of Hu Yanyan and others, Wu Xin and Cao Yi were also looking at the group of Hun cavalry in the distance on the city wall.

"Looking at the banner of these thieves, Hu Yanyan should be here!" Cao Yi said.

"Hu Yanyan is here, that is, he is here to die!" Wu Xin said confidently.

"If they don't want to jump into the river or go to the ravine, they must break through the city or escape from that road."

"General, I predict that the thieves would not dare to attack the city, they would only crowd that path." Cao Yi said very confidently.

"If the general hadn't had this trick to sprinkle water and turn ice into ice, how could he have the magical technique of building a city in two days!"

After hearing Cao Yi's praise, Wu Xin waved his hand modestly.

"Splashing water into ice to build a city is just a copy of the strategy of my predecessors, and I really don't dare to take it."

"However, what I am really satisfied with is forcing the Hulu to walk around the south!"

"According to military tactics, it can be said to be a conspiracy."

Wu Xin said confidently.

He had already predicted that the barbarians in front of him would not dare to stay too much, and would only choose the strategy of circling the southern path.

"Then let's wait for the Hulu to rush up and bite the hook." Cao Yi was also in a good mood.

After a long time, the Hun army retreated from Tongguan finally arrived.

For a moment, tens of thousands of Hun soldiers and horses filled the entire land like black ants.

With the emergence of the Hun army, the Han army prepared for battle on the "city wall".

Looking at the heavily guarded enemy defenders, Hu Yanyan and others finally gave up their plans to attack the city.

Because based on the information coming from behind, the fire in Tongguan has been greatly weakened.

It must have been that after the Han army entered Tongguan, they had already begun to put out the fire and clear the road.

This shows that the pursuers behind him may come to the scene at any time.

"Go and place all the elites in the front army, bring all the horses and food, and all the infantry without horses will be left in the rear army!"

Hu Yanyan issued an order to everyone, and the speed of the Han army coming from Tongguan was much beyond their expectations. Hu Yanyan and others had to show the courage to cut off their arm.

They had already planned to sacrifice soldiers without horses or lost horses and let them escape as rear troops.

"If the thief army comes out to intercept, there is no need to worry about them. Just go to Bainiuwu in front to join us!"

After Hu Yanyan said that, he ordered the entire army to launch an upcoming siege.

Although I have already planned to take a small path and escape, this drama still needs to be done well.

On the one hand, it is for the Han army ahead, and on the other hand, it is for the infantry that are about to be abandoned.

Otherwise, if the Hun infantrymen knew that they were going to be abandoned, they might just scatter, and they would also implicate those who could escape.

"Bang bang bang!"
