Trapped by the harassment of the dwarven rock sheep knights, the demonic alliance forces that were originally scattered throughout the Loess Plateau were forced to start moving towards the large cities where large quantities of food were stored.

And when the demon alliance took the initiative to abandon some small fortresses located on the choke point, those large cities on the Loess Plateau immediately became isolated cities.

Although the players under Daniels's account had told Daniels about the tactics to be implemented by the Condor Army in time, Daniels did not want to give up the Loess Plateau region to the Condor Army so easily.

In Daniels's view, since the Loess Plateau is destined to be lost, it is difficult for those alien troops stationed on the Loess Plateau to withdraw, so it is better to simply let those alien troops sacrifice more worthwhile.

Anyway, the grain and grass reserves in those big cities are very sufficient, so let those alien armies defend the cities to the death, and they can delay one more day.

As long as those cities are not breached for a day, those dwarven rock sheep knights of the Condor Army will not leave the Loess Plateau for a day.

Daniels plans to use the alien army that has defected to the Demon Clan to drag down the Condor Army's cavalry legions, and then use his own logistical supply advantage to directly drag down the Condor Army.

Daniels had already learned from the Northern Expedition that the Condor was having problems with logistics.

Now Ning Yuan has scattered millions of troops across the entire Loess Plateau, although the cavalry of the Condor Army is very powerful, those cavalry and the mounts under their crotches are not iron men, and they also have to eat.

Nowadays, the Loess Plateau is still dry and yellow, whether it is those big rock sheep or silver pegasus, they must eat the grain transported from the rear to fill their stomachs.

The dwarven knights were already more able to eat than the average human, and the big rock sheep and silver pegasus were even better than them.

When the food they carry with them is exhausted and they cannot be replenished from the vicinity, the logistical pressure of the Condor Army will be unprecedentedly strong, and they may have to take the initiative to withdraw from the Loess Plateau.

Daniels's little abacus clanged, and he directly saw through the essence of the Condor Army's strong and middle-class cadres.

If the situation really develops according to his vision, then Ning Yuan will definitely directly withdraw all the cavalry corps from the Loess Plateau, after all, the logistics and supply capacity of the Condor Army cannot cover the entire Loess Plateau.

However, Daniels's wishful thinking has a major premise, that is, those cities on the Loess Plateau that have enough grain and grass materials cannot be lost.

Once those cities are lost, then the Condor Army can get a lot of supplies on the spot, and the logistical hidden dangers will not exist.

Ning Yuan had already taken these issues into account when formulating the tactics of cavalry invasion of the Loess Plateau.

He knew very well that it would be difficult for his own logistical supplies to cover the entire Loess Plateau, so when he implemented this tactic, he was ready to fight for war.

......

Huanglong City is located in the Huanglong Mountain, which is an enemy city on the Loess Plateau that is relatively close to Hancheng, and it is also the first area to be harassed by the dwarven rock sheep knights.

After severing the connection between Huanglongcheng and the rest of the region, the Condor Army immediately launched a fierce attack on Huanglongcheng.

Because there are a large number of defenders in Huanglong City, and the Condor Army is unable to transport large siege equipment to Huanglong City in a short time, it is different from the previous siege mode, and the Condor Army adopts the siege tactics of aerial bombardment this time.

In the early days of the game, the Swan Clan was a nightmare for all terrestrial races, but with the widespread popularity of bows and arrows, the Swan Clan, who were relatively not very strong, gradually withdrew from the stage of war.

They collectively retreated to the second line and became glorious producers, providing all kinds of material support to the army at the front.

Although the Condor Empire has a large number of standing Swan Scout Corps, the number of Swan Scouts serving in the army is a drop in the ocean compared to the huge population of the Swan Clan.

And just when the Swan Clan themselves thought that the Swan Clan would no longer appear in the battle sequence of the Condor Empire's army, Ning Yuan suddenly temporarily requisitioned a large number of reserves of the Swan Clan to the Loess Plateau to participate in the war.

When they received Ning Yuan's order, many swan people couldn't believe their ears, and once wondered if they had heard it wrong.

When they repeatedly confirmed that it was really Ning Yuan's order, many ambitious swan people shed tears of excitement, and then enthusiastically signed up to join the army.

Although the orders given to them by Ning Yuan were strange, being able to return to the battlefield was already a great gift to the Swan Clan, so they faithfully carried out all of Ning Yuan's orders.

In this way, 300,000 young people of the Swan clan each went to the Loess Plateau with a basket, a small hammer, a dagger and a light crossbow.

When they reached the sky over the Yellow River, the 300,000 Swan Man soldiers first took a cold shower in the Yellow River and caught millions of kilograms of various Yellow River fish for the soldiers of the Condor Army on the front line.

Next, after a short repair in Hancheng, they immediately set off to the battlefield of Huanglongcheng.

After arriving at the battlefield of Huanglong City, the first task that the 300,000 swan people received was to use the hammer in their hands to create fist-sized stones, the more the better.

There is not much else on Huanglong Mountain, but there are many stones, and after three days of busyness, there are fist-sized stones piled up around Huanglong City.

When everything was ready, the Condor Army immediately launched a general attack on Huanglong City.

The first to strike was the Silver Pegasus Legion.

Taking advantage of the Silver Pegasus' ability to ignore the enemy's ranged attacks, the Silver Pegasus Knights successfully took cover for the Dragon Eagle Knights to the designated position.

After arriving at the designated position, the Dragon Eagle Knights immediately commanded the Dragon Eagle Beasts under them to begin unleashing the Cloud Mist Technique.

As thousands of dragon eagle beasts used the cloud mist technique at the same time, the entire Yellow Dragon City was immediately shrouded in thick clouds and mist.

When the clouds and mist enveloped the entire Yellow Dragon City, the defenders of the city immediately turned blind.

And at this time, 300,000 swan warriors with baskets on their backs were dispatched.

With the help of the cover of the clouds, they quickly flew to the sky above the Yellow Dragon City, and then kept throwing the fist-sized stone in the back basket.

Due to the obstruction of vision, the defenders of Huanglong City did not know what was above their heads, and they feared that the Condor Army would approach the city through the clouds and mist, and then launch a surprise attack directly.

Therefore, many soldiers never moved their positions from beginning to end, and they always stuck to their posts.

And when the swan warriors spread all over the sky and kept throwing fist-sized stones, many unprepared defenders of Huanglong City immediately won the bid and let out all kinds of screams.

Falling objects from high altitudes, this is the perfect siege tactic that Ning Yuan wants to use on the Loess Plateau.

The reason why Ning Yuan was able to think of this tactic was not only because he had been one of the victims of the Swan Clan's cruelty before, but also because a similar tragedy had just happened in the community where he lived.

An innocent passer-by was hit on the head by a shampoo bottle that fell from a height, and after being sent to the hospital, rescue failed, and he died directly.

After learning of this tragedy, Ning Yuan specially inspected the news related to the falling object.

It turned out that an egg weighing 30 grams was thrown from the fourth floor, and it would smash a swollen bag on the top of a person's head.

And throwing it from the eighteenth floor can directly smash a person's skull.

If thrown from the twenty-fifth floor, the impact is powerful enough to kill a person.

So don't underestimate an egg, if it falls from a high altitude, it is no less powerful than a bomb!

After reading the introduction of the falling object from high altitudes, Ning Yuan was so frightened that he immediately put away everything on the windowsill, for fear that when there was a strong wind one day, he would suddenly blow down and hit passers-by.

While feeling frightened, Ning Yuan was keenly aware that falling objects from high altitudes could also be used in war, and the Swan Clan, who had brought him this kind of damage, was the best candidate.

Although there are many flying races in the Condor Empire that can perform this high-altitude falling object tactic, the Swan Clan has an innate advantage over those races.

First of all, the food consumption of the Swan Clan is much smaller than that of other races, as long as there are lakes and rivers, they can be replenished in situ, which is very important for the Condor Empire, which is now under relatively high logistical pressure.

Secondly, the Swan Clan have a very large population, and their durability is excellent, making them the perfect candidate when it comes to only the use of stone-throwing tactics.

Finally, the Swan can switch from battle mode to production mode at any time.

In places where logistical supply is difficult, as long as there is enough food in the water, they can not only solve their own food and clothing problems, but also provide food support for other armies.

They can act as slingers in siege warfare, use their flight advantage to act as the eyes of ground legions, and can always be incarnated as fishermen and hunters to provide logistical support to other armies.

In addition to not being very good at combat effectiveness, they are simply a rare all-round support class.

Originally, in siege warfare, the lack of long-range attack ability of the Swan Clan was a fatal weakness, and it was difficult for them to get close to the city under the long-range fire attack of the defending army.

However, when the Condor Army had the Silver Pegasus Legion and the Dragon Eagle Knight Legion successively, the long-range attack they feared the most was no longer a problem.

When the city is covered by the dragon eagle beast's cloud and mist technique, the defenders of the city will become blind.

It was impossible for the soldiers defending the city to shoot arrows indiscriminately into the air without seeing them, for if they did, they would probably suffer first.

At this time, the swan army can take the opportunity to fly over the city.

By the time the enemy inside the city noticed that someone was throwing stones downwards overhead, it was already too late, and under the covering attack of the rain of stones, it was impossible for the defenders, who could not see what was happening, to organize an effective long-range attack.

The above situation is a result that Ning Yuan has repeatedly deduced, but the fact is even better than the result that Ning Yuan deduced.

A fist-sized stone fell freely from a height of fifty meters, which is equivalent to the height of a twelve- or thirteen-story building in modern society.

Thirty grams of eggs can smash a person's skull if they fall from eighteen floors, and a fist-sized stone falls from a height of fifty meters.

After the entire city was shrouded in the cloud mist spell performed by the dragon eagle beast, the defenders in the city at that time agreed that the condor army ape army outside the city would take the opportunity to launch a surprise attack on the city wall.

They were so focused on the defense of the walls that they didn't know anything about what was going on overhead.

So when it suddenly rained stones in the sky, they didn't have time to dodge at all.

At that moment, the stone rain that fell from the sky basically meant where to smash, and whether or not it could survive the stone rain depended entirely on whose face was whiter.

The lucky Emperor Ou was unscathed in the rain of stones, and not a single stone could hit them.

Those who were a little less lucky were unfortunately hit by stones falling from the sky on the shoulders and other parts, and although many people suffered fractures, swelling and other injuries as a result, they directly lost their ability to fight, but their lives were finally saved.

The black-faced ones were unfortunate when they were hit on the head by a falling rock and immediately lost consciousness.

This kind of injury is difficult to rescue with the medical conditions of modern society, and in ancient times, when the medical conditions were relatively backward, it was basically equivalent to direct death.

After the swan warriors in the sky finished throwing a basket of stones, the defenders of Huanglong City had already suffered more than half of the casualties.

As for the unorganized counterattack of the defenders in the city deduced by Ning Yuan, it did not appear at all.

In a situation where the sky is full of stones, people's first instinctive reaction is to rush to find cover to save their lives, in that case, there are no defenders who want to shoot arrows into the sky to fight back.

When the clouds and mist over Huanglong City dissipated, the entire sky over Huanglong City was empty, and the 300,000 swan warriors had successfully retreated to their own safety area where the stone bullets were stored.

When the defenders came out of their bunkers and looked at the empty sky, countless question marks appeared in the heads of many people.

While many of the defenders inside the city were still in a state of confusion, the ape-man legions outside the city began to approach the city.

Before there was time to think about it, the defenders of the city, under the orders of officers at all levels, immediately began to take their positions and prepare for the upcoming siege battle.

However, the ape-man legion outside the city suddenly stopped after advancing some distance.

Just when the defenders on the city wall were wondering, the Dragon Eagle Knight Legion, which had passed the cooldown of the Cloud Technique, rushed to the city again under the cover of the Silver Pegasus Legion.

When the Cloud Mist Technique used by the Dragon Eagle Beast once again enveloped the entire city, the defenders of Yellow Dragon City immediately remembered the terrifying stone rain just now.

At this time, they didn't care whether the enemy outside the city would take the opportunity to sneak attack the city wall, and the moment they saw the clouds appear, the defenders in the city began to look for cover, and the defenders who couldn't find the cover raised their shields one after another to protect their heads.

Sure enough, it rained stones in the sky again.

Due to the well-prepared soldiers of the defenders this time, the casualties were not very large compared to the first time.

However, just as the defenders were secretly glad that they had escaped again, some tall black figures suddenly appeared on the city wall.

As the clouds and mist cast by the dragon eagle beast gradually dissipated, the true colors of those black shadows were gradually revealed, and they were the ape warriors who had been guarding outside the city.

After discovering that the defenders in the city had suffered heavy casualties, the general of the Condor Army, who was in charge of the siege, immediately sent the ape-man legion forward.

Under the cover of cloud magic, the ape-man warriors successfully climbed the top of the city using ropes.

As soon as the clouds at the head of the city had cleared, they rushed to the defenders who were still stunned.

When the ape-man warriors charged, the knights of the Silver Pegasus Legion also took advantage of the situation to enter the city.

Under the onslaught of the two elite Condor armies, the defending forces that had already suffered heavy casualties and low morale were quickly and completely defeated.

After besieging Huanglong City for thirteen days, it took less than three hours for the Condor Army to directly capture the entire Huanglong City.

In this battle, 300,000 swan warriors played a crucial role, and their stone rain offensive directly wiped out half of the defenders in the city, relieving great pressure for the subsequent general attack.

After hearing the good news of Huanglong City, Ning Yuan was immediately overjoyed.

When he learned the whole battle in detail, he suddenly remembered a phrase that players often mentioned: there are only waste lords, and there are no useless races.
