The expeditionary legion of the three forces has finally gained a foothold in the desert kingdom.

After that night's surprise attack, fifty percent of the expeditionary force strategically retreated back to China, and after sufficient supplies, it would cross thousands of miles of desert again to join the army. Although this practice is indeed a waste of time and money, it is still the safest way.

The retreating forces were mainly heavy cavalry units that were difficult to use in the desert terrain, and their exaggerated weight made it impossible to speed up when running in the yellow sand, and the speed of the charge was enough for even the stove soldiers of the cooking squad to catch up with them.

When these heavy cavalry units return to their respective countries, they will no longer participate in the expedition, but will be replaced by more flexible and resource-efficient light cavalry.

No matter how powerful the arms are, they must also be used in consideration of the actual environment of the battlefield, and it is obvious that this expeditionary campaign has taught many commanders of the old and new generations a vivid lesson.

However, what made countless soldiers feel the most indignation was the fact that the former vultures joined the arms of the desert humans and killed them, and after that, there were even vicious incidents of soldiers who lost their minds and mutilated the corpses of vultures.

As for the vulture tribe's "surrender to the enemy", it is divided into two distinct parties.

The side led by the Swan Clan is naturally ashamed and angry at what the Vulture Clan has done, and the same orcs have killed their former compatriots, and even did not hesitate to practice their dignity to become the mount of the desert humans, and the crime should be punished.

However, many more are quietly standing on the opposite side of the swan clan.

The vultures did not join the military department, but volunteered to guard the border near the desert kingdom against smugglers and desert bandits who crossed the border wantonly, but this merit was not recognized by the kingdom.

This is not only that, a large swan clan actually suppressed a series of absurd and absurd reasons such as the vulture clan's ugly appearance and lack of "elegance", and the vulture clan who practiced unyielding temperament in the whistling wind and sand naturally did not bow their heads, and was later forcibly expelled from the orc kingdom by the swan army with a numerical advantage, and expelled from the country.

The Swans, along with the Rhine Lion and the Tiger Tiger, were the three ancient nobles of the Orc Kingdom, and many people were upset by the tragic plight of the Vultures, but these voices were brutally suppressed in the end.

You ignore the honor and rights of others, expel others from your homeland by force, and brutally draw a ruthless mark in the kingdom's ethnic statistics, directly removing the vulture tribe from their place of origin. Vultures who have lost their homes have been exiled to the desert, how can human beings survive without desert refuge? Now that they meet each other on the battlefield, they still want others to remember the feelings of their former compatriots? What did you swan do a long time ago?

The Swan Clan's handling of this matter can be described as extremely poor.

Since that war, the importance of clean water has been elevated to a strategic level, and the expeditionary force has drawn a large circle on the military map, requiring each wing to compete for all the oases with clean water resources in the territory.

All the commanders who had seen the military map were bitter.

The radius of that large circle was at least about 100 kilometers, and the desert march was far from easy than fighting on the plains, and they were fighting away again, so they had to be busy.

The oases in the desert were populated by desert kingdoms, the larger oases were led by armies, and the smaller ones spontaneously formed guerrilla groups.

The wings began to come into frequent contact with the guerrillas of the desert kingdom, suffering losses from each other.

However, after they fought hard to occupy the oases, they found that all the oases had been poisoned and destroyed by desert humans, and there was not a drop of water to drink.

Rommel's ruthless plan shocked everyone.

Clear water resources are a one-time consumable in the desert, and the water storage in a huge oasis can indeed make the expeditionary force not need to worry about clean water for the time being, but the consumption of hundreds of thousands of troops stationed in the desert is too amazing, and the natural adjustment of the oasis ecology alone is far from enough. Once the water is gone, there is no need for Rommel to attack them, and they themselves will kill each other due to the extreme lack of water.

Therefore, the expeditionary force is also fighting with Rommel, they think that Rommel will never poison all the oases, at least those oases where there are still desert guerrillas stationed must still have clear water, they will take it anyway!

......

67 kilometers west of the base camp of the expeditionary force, the weather is sunny and the visual distance is good.

A mixed wing took advantage of the cover of the dune terrain to reach an oasis 15 miles away.

A telescope peeks out from behind the dunes, Silvergray squints at the oasis' fortifications, and a full-fledged snow eagle on his shoulders pecks at his feathers, proudly like a victorious general.

The fortifications of this oasis were built differently than elsewhere, with two 60-degree angles cut into the middle of the two-meter-high circular earthen wall, which was very tricky, and if a stormtrooper attacked, it would inevitably be scattered by this angle, and it was possible to form an encirclement by the enemy behind the two corners.

In addition, the defense of this oasis is obviously much larger than that of other oases, and the fortifications are so professional, it will definitely not be easy to capture this oasis.

"These desert humans don't seem to be guerrillas, more like regular troops. An elven officer next to Silver Ash said, his eyes flashing a little green from time to time, indicating that he was also a veteran archer with amazing eyesight, and could see distant targets.

The elf race has to be said to be indeed elegant to the extreme, their bodies seem to have some kind of efficient thermoregulation mechanism, in high temperatures, the body temperature of their bodies will drop with the drop, and the skin will be cold to the touch, so that they will not sweat like the orcs, and they have always maintained an elegant posture.

What's more, under the regulation of this mechanism, their water intake will also be reduced accordingly, making them the least water-consuming race in the expeditionary force.

"The outer side of the leather armor of these desert humans is uniformly equipped with protective gear made of similar beast bones, which is not at the same level as the guerrillas we encountered before, and these guys are naturally the regular army of the desert kingdom and have not run away. Silver Ash put down the binoculars and said.

Due to the professionalism of Guangye in the night counterattack and the recent encounters with the desert guerrillas, as well as the proud record of creating no one killed, the wings that carry out missions with the Guangye troops will subconsciously follow their advice or simply let them command the battle.

It turned out that their choice was extremely correct, and the other wings and the desert guerrillas would pay a lot of price when encountered, but the team with the participation of Guangye had a battle loss rate of only a fraction of that of the other wings, and the difference between them could be described as a cloud of mud.

However, even Silver Gray, who was proficient in combat, didn't know at the moment that the oasis in front of him was actually far from being as simple as he imagined.

"My lord, the other party is approaching, about 2,700 people, a wing or so. A dark-cheeked desert man lying on the ground, his ears were particularly large, and he stood up for a long time listening to the ground, pointing to an inconspicuous sand dune 15 miles away.

The regular army of the Desert Kingdom will train soldiers who are capable of listening, and they can hear the number of enemies without using their eyes, and even the difference between the footsteps of their mounts and soldiers.

"Good time!" the leader of the regular army wiped his bushy beard, climbed up to the corner tower with a few clicks, and shouted, "Cut down all the date palm trees around!"

The desert soldiers immediately did so, they took out their shiny scimitars, climbed up the date palm trees about ten meters high with a few clicks, and began to chop from top to bottom, these well-made desert scimitars were extremely sharp, and soon cut down the date palm trees into several sections.

As the dense date palms fell in drools, revealing what looked like a tower hidden in the palm palm, a desert soldier jumped onto them, muttering something respectfully before striking the tower with the hilt of his sword.

With a click, the outer crust of the earth-stone tower shattered, peeling off the ugly shell like an egg, revealing the silver glimmer of the spire standing proudly inside.

Twenty-four minarets, which enclose the entire oasis, appear to be made up of prisms at the tops of these pinnacles, reflecting dazzling light from them.

Daniman, the bearded leader, raised his head and squinted, looking at the spires that looked like works of art, as if looking at the stunning beauties.

These minarets are called the Prism Towers and are the pinnacle of craftsmanship in the Desert Kingdom.

Compared to other countries, the Desert Kingdom has had its own splendid civilization, and the craft of glassmaking is what they are most proud of.

Desert humans discovered a long time ago by chance that if the lens is ground into a convex lens and placed in the sun, the sunlight will be gathered into threads, and the heat of the light will also be concentrated, and its burning ability can burn reptiles such as ants.

This discovery was significant, but apparently it was not satisfactory to kill the ants, so the most skilled craftsmen of the Desert Kingdom at that time finally made the most perfect convex prism from a material called "Star Crystal" through continuous experimentation.

These convex prisms were sent to the Desert Royalty, where they were blessed with magical effects that further concentrated heat and light by court magicians before they were finally finished.

The finished prism of the blessed magic is framed on a spire made of stainless steel, a total of 8 sides, and after absorbing sunlight, it can shoot extremely hot light at 8 angles around it, and this kind of beam of light can burn the standard armor of the orc kingdom, not to mention the flesh, it can directly burn people into a fireball.

Crowned by the Desert Kingdom as a prismatic secret weapon, it absorbs the sun's rays and the moon's reflections. The desert is the most sunny in the desert, and the scorching sun is scorching all year round, so that these prismatic towers are almost always in a state of full energy.

The Desert Kingdom, which possessed this thermal weapon, could have used this high-end technology to break through its territory and further expand its sphere of influence. Unfortunately, this technique was stagnant for a long time, and the craftsmen could not think of a way to turn the ten-meter-high Prism Tower into a more portable mobile weapon.

There are not enough prism surfaces, the striking range is one-sided, and it is not practical;

Reduces the height of the prism tower, but it affects the recharge speed of the prism tower, which is not practical;

Switching to a material other than the Stardust Crystal will greatly reduce the power and make it impractical;

When the prism tower is moved to an area with insufficient sunlight, its performance decreases and it is even less practical.

The craftsmen and armies of the Desert Kingdom finally discovered that the Radiant Prism Tower could only be used to defend the home, and there was really no better solution for the active attack.

A prismatic tower is staffed by three desert soldiers, one of whom is responsible for command and coordination, one for observation, and the last one for turning the prism to calibrate the firing point.

Silver Gray's wing had noticed the oasis's movements, and the big guy looked at the silver shining spires, not knowing what those things were for.

Panta, who was beside Silver Ash, frowned, and he vaguely sensed that something was wrong.

There was not much information that could be learned from this angle, Silver Gray pondered for a moment, his shoulders shook, and the snow eagle that was connected to his heart immediately spread its wings into the sky.

The snow eagle flew towards the oasis, its eyes scanning the oasis beneath it.

The vision between the snow eagle and the silver gray is shared, and what the snow eagle can see, the silver gray can also see clearly. Looking down at the oasis from a high vantage point can be more useful, and Silver Ash can now see that the desert soldiers in the depths of the oasis are mobilizing on a large scale.

Now he was convinced that this oasis was not an ordinary oasis at all, it was simply an outpost of a heavily guarded desert kingdom!

"There are horneed beasts in the wing, do you want to let them explore the enemy's bottom first? The desert soldiers' archery skills are so-so, and it is difficult to threaten them. The elven officer suggested. As a veteran elven archer, he is indeed qualified to evaluate the archery skills of the desert soldiers as inferior.

"It's okay, if you can destroy those glowing towers, try to attack, but be sure to put safety as the first premise!" Considering that these wildebeest beast riders are all elves and experts in playing with bows and arrows, Silver Gray also thinks that there is no reason why they can't dodge the bows and arrows of the desert soldiers, and there are no vulture knights in the vicinity, so they should be safe.

Silver Ash summoned the Snow Eagle, and four wildebeest riders took off and skimmed over the dunes, elven riders with Blackwood Bows clinging to their mounts.

The wildebeest riders reached the sky above the oasis with a high altitude advantage, and the desert soldiers raised their bows and shots, and these elven riders of the affinity wind element were extremely skilled, swimming in mid-air, dodging wave after wave of volleys, and seemed to be at ease.

Danneman sneered as he looked at the wildebeest beast rider hovering over the oasis.

Perhaps it was the opponent's inaccurate attack that paralyzed the four knights, and they dropped in height, flying around a prismatic tower, bending their bows and firing arrows that had no effect on the surface of the prisms, which were as indestructible as diamonds.

"It's too low! It's too low! If you lose your mobility, you'll get into trouble!"

As if to confirm the words of the silver ash, the prismatic tower lit up with an unusually dazzling light without warning, and the silver beam of light enveloped the two air riders in an instant, and the two air riders and the wildebeest beast were burned into two fireballs before they could react, and they didn't even have time to land, they burned into two charcoal bodies in mid-air, and smashed a burst of ash on the ground.
