The power of the Undead Scourge enveloped the entire base, and all the beastmasters within were pulled aboard the base's towering walls for defense.
The city itself was equipped with many enormous towers that were even taller than the city walls.
These towers form the ground-based air defense force of the entire base. They are evenly distributed throughout the base and together with the air-based combat forces, they form an air defense system.
Moreover, human power is not limited to beast tamers, but also includes Primordial Technology and Dark Energy Technology!
Chirp! Chirp! Chirp...
The first wave of fire came from long-range attack weapons hidden within the city walls and fortresses: rocket launchers.
Countless rockets roared into the distance, like dense raindrops, evenly scattered across the entire sea of undead skeletons.
A single rocket launcher can destroy at least 10 to 30 skeletons with the force of the gunpowder. The entire city wall hides tens of thousands of fixed rocket emplacements, each equipped with at least 30 box-type rocket launch tubes.
In this first wave of attacks, at least one million undead skeletons were destroyed.
Then, human defenses quickly replaced the rocket canisters, and the second wave of rocket artillery attacks was launched.
Although Jiang Ziliu is far away, he is now Gold Rank life form.
His eyesight alone was already extraordinary; he could see images from tens of kilometers away, as if his eyes had become an astronomical telescope.
His soul power, exceeding one hundred thousand, greatly amplified and expanded his vision and field of observation, allowing him to see a wider, clearer, and more distant world.
For example, a normal person can see three colors, and all other colors are combinations of these three colors.
However, Jiang Ziliu could see the most essential color categories, which were eight!
This is the difference between Gold Rank life forms and ordinary life forms after their transformation.
He could easily observe all activities throughout the base.
The entire scene of humanity's counterattack was clearly presented in his field of vision.
Rocket launchers are a very cheap area-of-effect weapon that remains useful even in this day and age, and are even cheaper thanks to the skills of Beastmasters.
For example, a beast tamer who possesses fire-related skills can collaborate with a beast tamer who possesses steel-related skills, and with some additional knowledge, they can create hundreds of precision metal parts a day.
Beastmasters with Metal Manipulation skills can freely extract massive amounts of metal from poor-quality ores. The entire process is not only environmentally friendly but also low-cost and highly productive, easily producing hundreds of tons of metal per day!
The Beast Taming Feedback skill brings a terrifying boost to human production capacity, making previously simple technological creations much cheaper.
Only information industries like the internet are difficult to fully realize.
Because the interference and destruction caused by the strange beasts are too powerful, the unorthodox methods are difficult to defend against.
The core challenge lies in the technology and production capabilities related to beast taming, which also represent a significant difficulty.
Under such circumstances, humans can easily achieve mass production of rocket artillery.
In this region, humanity's ability to deal with the Undead Scourge has long been maximized, and rocket artillery, a cheap and efficient weapon against the undead horde, has also been used to its fullest potential.
In less than an hour, the human base's defensive walls had been hit by ten rounds of rocket artillery fire, eliminating at least 20 million undead skeletons.
The advance of the undead skeleton horde towards the base was effectively halted by the power of the rocket artillery.
The fierce battle in the sky also continued.
The weapon used by this type of weapon against ghosts is the anti-aircraft gun, which is also very cheap and inexpensive, but the shells used in this type of anti-aircraft gun are made of very special materials.
When it explodes at high altitude, it will directly form a large cloud of dust.
This dust cloud covers an extremely large area, but it is made using a special, extraordinary material: the Dust of Light.
This is a type of dust produced by soaking materials in a luminous liquid called holy water.
It contains very little light-type power, but it can effectively suppress ghost-type power.
The dust created a dust cloud that spread across the sky, having a slow, lethal effect on the ghosts and also forming a protective canopy over the base.
At the same time, explosions at high altitudes can also effectively kill ghosts.
However, these are not the most powerful anti-air methods. The most powerful one is atop a tall tower in the base, where there is a special Sun Holy Crystal, a special SS Grade crystal that combines both holy light and solar attributes.
Once activated by the rune array, it generates intense holy light.
If ghosts or other undead creatures get too close, they will be annihilated by the high-intensity holy light above them.
The spirits of the dead are not afraid of sunlight, but they fear a special kind of holy light.
This single Sun Holy Crystal is enough to protect the entire base's sky. All the ghosts can do is launch a concentrated attack or send powerful warriors down from the clouds to destroy the Sun Holy Crystal.
However, the entire base is protected by a special energy shield; without breaking through it, even the strongest members of the Undead Clan cannot get through.
The ghosts were able to break through this energy shield, but they were completely suppressed by the Sun Holy Crystal.
It will continue to serve a defensive purpose until its energy is depleted.
The army of Yin Corpse from underground has also approached this place, and the Human Race has prepared methods to deal with them.
Beneath the base city, humans have created a unique multi-layered underground space. In the walls of this underground world, humans have added a fire-based material specifically designed to counter the Yin Corpse, in order to defend against their underground attacks.
The Yin Corpse can travel underground, but they can be restrained by the power of fire; the aura of fire can even kill them.
They have a strong ability to penetrate the ground, but are relatively weak in other aspects.
Their only option, like the ghosts and skeletons, is to use their sheer numbers to slowly wear down the entire base's defenses, resources, and massive energy reserves.
The mid-to-high-level powerhouses of the undead race remained behind the Sea of the Dead.
The Gray Rock Grade undead have little consciousness and can only mechanically obey the commands of the higher-level undead.
The Black Iron and Bronze Rank undead have developed some Wisdom, but they still instinctively obey the orders of their superiors.
Only Silver Rank and Gold Rank undead life forms have evolved into fully Wisdom life forms.
Like humans, they possess Wisdom and the instinct for self-preservation.
In this attack, the Silver Rank and Gold Rank undead beasts were all directing from the rear, allowing the low-level forces composed of ghosts, Yin Corpse, and skeletons to attack without regard to numbers or cost, using their lives to wear down the human's physical strength, energy, and resources.
Since there are so many low-level undead, they are not afraid of being consumed.
If the attack fails, these Silver Rank and Gold Rank undead creatures will not choose to fight to the death; they will only prioritize self-preservation.
High-ranking undead obey the Undead Race. They only attack when the numerical advantage of the Undead Scourge is in place, allowing the Undead Scourge to deplete the power of the human strong, so that they can crush the enemy with an absolute advantage.
This is the unchanging modus operandi of the Undead Race to control undead beasts for millennia.
They would preserve high-level undead beasts and consume low-level Undead Clan, selecting the strongest among the undead through repeated wars.
For them, low-level undead can be easily created, but high-level undead are a matter of probability, and must be cherished.
This set is also very useful.
Humans knew this pattern and made targeted preparations.
However, the human population and resources are limited. When the number of undead controlled by the Undead Race reaches a certain point, that will be the moment when they gain the upper hand!
