In the night, the gate of Yonggu City was wide open, and the Xuanzi battalion led by Song Ying'an cautiously and quietly touched out of the city gate.

The hooves of all the horses were wrapped in cloth, and the muzzles of the horses were chained with harnesses, and it was impossible for a party of nearly 3,000 men to leave the city without alarming the barbarian cavalry that was constantly cruising outside the city.

In a short time, a barbarian scout shot an arrow and sounded a warning horn.

At this time, the entire team only had more than 500 soldiers out of the city gates, but these people were all carefully selected elites, including 200 cavalry.

If you want to rely on the few war horses to directly attack the barbarians' defense line, maybe those cavalry may escape by themselves, but the more than 2,000 people who followed behind will definitely not be able to keep up with the speed of the cavalry with two legs!

Therefore, this breakthrough, whether it is Song Ying'an, who was in the battle formation, or Zhang Chaoyang, a veteran who was guarding the city, they have all carried out countless deductions on the map.

Seeing that his whereabouts were revealed, Song Ying'an and the soldiers of the Xuanzi battalion did not panic, but continued to advance in an orderly manner.

The 200 cavalry began to divide into ten-man teams, like hunters, hunting the ranger scouts sent by the barbarians in the darkness of night.

After the large-scale equipment of hand crossbows, the cavalry of the Xuanzi battalion and the barbarian cavalry did not suffer when they met in short arms, on the contrary, as long as the distance was close enough, the more convenient hand crossbows were often more effective than the bows and arrows in the hands of the barbarians!

It's just that those barbarian cavalry are skilled in horsemanship, and the range of bows and arrows exceeds that of hand crossbows, and the cavalry of the Xuanzi battalion will inevitably withstand a wave of bow and arrow attacks if they want to close the distance.

During the siege of the barbarians, Yonggu City was not blindly beaten passively, and the cavalry in the city also had the opportunity to go out of the city from time to time to fight back.

The cavalry of the Xuanzi battalion relied on the cover of the night, and met the enemy with a team of ten people, occupying the advantage in numbers, and fought with the barbarian scouts, and did not fall behind, but quickly cleared most of the scouts cruising outside the city gate.

The rest of the barbarian scouts, relying on their skillful horsemanship and vigorous horses, all withdrew to the camp in the distance.

At this time, the Xuanzi battalion that was preparing to break through had all rushed out of the city gate, and after Song Ying'an's continuous training, although the Xuanzi battalion at this time was a little chaotic, the formation was still there, and after a little adjustment, he went straight to the barbarian camp in the distance to rush over!

For a long time, the barbarians besieged Yonggu City but did not attack, and the intensity of the battle between the two sides was not high.

Except for the occasional cavalry sent by the defenders of Yonggu City to fight the barbarians, which was used to train their cavalry qualities, they did not take the initiative to attack.

And all along, the psychological advantage that the barbarians have formed over the army of the Great Yan Kingdom has made the barbarians besieging Yonggu City take it for granted that these Han people cowering within the tall city walls are no different from the Han people they have encountered in other places before!

It's all a few cowards who are fleeing from the wind, weak like grass chickens on the grassland!

Not to mention the ordinary soldiers, even the leaders of the barbarians never thought that the Han soldiers in Yonggu City would take the initiative to go out of the city on a large scale, take the initiative to abandon the tall city wall, and choose to fight against themselves in the wild!

It is precisely because of this habitual thinking that the assault of the Xuanzi Battalion has become extraordinarily smooth and unexpected!

The barbarians stationed in the camp in front of them have been accustomed to the defenders of Yonggu City cowering in the city, relying on the trebuchets of the city to resist the steel knives from the steppe warriors, so in the camp, from the leader of the whole army to the Han people who were plundered as slaves, no one thought that in this ordinary night, the defenders of Yonggu City would take the initiative to attack the barbarian camp at night!

By the time the barbarians in the camp woke up from their sleep, the shouting and killing sound from the Xuanzi camp was already close at hand!

It can't be blamed that these barbarians are too negligent and treat the war as a child's play, but it is really that the army of the Great Yan Kingdom they encountered before was too stretched.

Since these barbarians entered the hinterland of the Great Yan Kingdom, all the barbarians they have encountered are Han people who have fled from the wind, holding their heads and running around, and the defenders in those places are all yellow and thin, dressed in tatters like beggars, and the blades in their hands are all rusty garbage that has not been replaced for I don't know how many years!

The purpose of the existence of those people seems to be to allow warriors from the steppes to practice how to ride on horseback and cut off the heads of their enemies!

The inertial thinking that has always been carried out, coupled with the loose organizational structure of the barbarians gathered together as a tribe, led to the incomparable success of this night raid of the Xuanzi Battalion!

Even if there is a scout warning released according to the custom, there is still chaos in the barbarian camp, Song Ying'an, who is well versed in the way of using soldiers, naturally will not let go of such a good opportunity, it is a breakthrough, and it is impossible for a team of more than 3,000 people to sneak over quietly under the noses of the barbarians.

Song Ying'an, who had countless deduction experiences about the current situation, simply ordered the whole army to go straight to the barbarian camp!

In stark contrast to the soldiers of the Xuanzi Battalion who roared and rushed towards the enemy camp, were the generals and their own soldiers who followed the rear of the ranks.

Although these guys felt that it would be extremely safe to break through with Runanbo, but when they actually came out of the gate of Yonggu City with the Xuanzi Battalion, and the gate that had provided them for many days of protection was tightly closed behind them, these guys couldn't help but become scared.

There were countless shouts of killing in the night, and when the Xuanzi battalion completely broke into the barbarian camp, these gentlemen who came to the border army to make merit fell into a state of chaos irrepressibly.

This kind of change was completely unexpected by Song Ying'an, in the countless previous deductions, he and the veteran Zhang Chaoyang had excluded these generals and their personal soldiers from all battles, and the orders given to these people were only to closely follow the Xuanzi battalion soldiers who rushed to kill in front.

As long as they rushed through the loose defense line of the barbarians, as long as they jumped out of this encirclement, even if the barbarian army had the advantage of cavalry, it would not be able to form a real and substantial damage to this team.

After all, behind the barbarian defense line, the imperial court had already transferred a large number of troops to respond.

Regardless of whether those armies were combat-ready or not, the number and size of the terror alone was enough for the barbarians to have to deal with it carefully.

Even Song Ying'an and the Xuanzi battalion received an order that once they broke through the barbarian defense line, they would not make any stops, and retreat in the direction of Jiangling Mansion by water with Runanbo Chen Yongzhong.

Yonggu City is only a hundred and ten miles away from the dock that can transport soldiers on a large scale, as long as it can break through the defense line of the barbarians, the Xuanzi battalion with Chen Yongzhong and a group of generals is nine percent sure that they will evacuate safely!

But it's such a simple and clear tactical arrangement, but there is a problem with those gentlemen who don't have to be in charge of fighting!

When the Xuanzi battalion completely destroyed the barbarian camp, he was shocked to find that the generals who were supposed to follow closely behind him had lost a lot!

Chen Yongzhong, Runanbo, is nowhere to be found!
