The edge of the central zone.
In the clear blue sky, there is a large black cloud.
This dark cloud seemed to be fixed by something and stayed in the same place. Even a hurricane could not blow it away.
The thick, dark clouds blocked out the sunlight, and darkness enveloped everything below.
If someone walked into the darkness under the dark clouds at this time, they would feel the biting cold, as well as wailing, screaming, and strange laughter coming from nowhere, and a huge monster looming in the darkness.
It was a darkness as dark as a ghost cave.
This situation has been going on for a whole week.
Li Ziyu himself had not expected that upgrading from a fortress to a castle would cause such a big commotion and could even cause strange phenomena.
Fortunately, the central area has been basically cleared, and he is in the undead territory close to the wasteland death zone. Otherwise, this situation of dark clouds not moving will definitely attract curious people.
From the moment I chose to upgrade, dark clouds inexplicably formed in the sky, covering the entire fortress.
Under the operation of the system, the Undead Fortress changed day by day, and gradually became unrecognizable even to Li Ziyu.
Upgrading a castle is completely different from upgrading fortresses and strongholds before. This is a major update.
The walls, buildings, and landforms of the Undead Fortress have all changed.
The bones merged into long bricks, and undead runes were engraved on them. Spiritual energy surged on them, and each rune glowed brightly.
Long bricks were stacked up to form a city wall that was wider, thicker and taller than before.
The thickened bone plates and thorn wall panels that were installed before...all disappeared and merged into the wall.
The new city wall is called - the Wall of Despair!
【Barrier of Despair】
[Level: Castle Level]
[Category: Building-Main City Level]
[Introduction: The Bastion of Despair is an advanced wall defense system created by the Undead. Its bricks are constructed from dormant Undead Skeletons and Wraiths. When engaged in combat, the Bastion of Despair will spontaneously activate basic buffs such as "Solidity," "Hardened," "Repellent Thorns," and "Armor-Piercing Spear," as well as psychic protections such as "Rebound," "Reflect," "Intermediate Magic Immunity," "Psionic Shield," and "Magic Flame Ring."]
[Skill: Despair Collapse - Disintegrates the entire wall of the Despair Barrier, releasing the seals on the dormant evil undead and evil spirits, allowing the wall to transform into countless undead to attack any enemy who dares to invade.]
Li Ziyu's eyelids twitched as she watched the introduction.
Damn, who can break this thing?
The dual blessing of physical defense and psychic defense is for fear that the defense is not enough.
The city walls have their own unique skills, which is so scary.
Not to mention the original abilities of the city wall, just talking about the skills of the city wall, he could imagine what the enemy would look like when facing his city wall. When they were about to break through the city wall, they would activate their skills, and then the city wall would collapse and turn into a vast number of undead, rushing towards the enemy.
No wonder it is called the Barrier of Despair. Facing such a wall, it is indeed quite hopeless.
That’s it, and they are all basic models.
The Wall of Despair can be further expanded. For example, the corridors of the city wall can be widened to accommodate more soldiers and place cannons that are built later.
Small bunkers can be built on top of the city walls to protect the undead from harm.
There are also towers, such as arrow towers, turrets, magic towers, and psychic towers, all of which have reserved space.
There are even landing platforms specifically for flying cavalry and flying creatures.
In addition to the above, there are also corner fortresses, parapets, etc. that can be built.
To make the Wall of Despair more effective, not only defensively but also offensively, you need to add and build other things.
However, these things are not free, they require resources, and the price is not low.
The upgrade of the castle, just the city wall alone has already made Li Ziyu very surprised, and inside the city wall, the upgrade of the mobile fortress has not been completed yet and is still in progress.
Inside the city wall, the changes are even greater than the city wall itself, and the terrain has changed.
Originally, the mobile fortress was a super huge platform, and the upgrade only meant changing the bone plates on the platform.
Now a large area of bone plates have disappeared and turned into black mud.
The soil surged, as if the bottom of the crust was pressed up, piling up in the center of the Undead Fortress, constantly rising, and at the same time strangely hardening.
The hardened soil had a metallic luster and formed a mountain hundreds of meters high.
There is a naturally formed passage on the mountain, with steps automatically forming one by one, leading to the top of the mountain.
At the top is an extremely spacious platform, on which the main building of the Undead Fortress is located.
This change was unexpected for Li Ziyu. He felt that it was too un-"undead".
He could understand bone plates and the like, and the styles were all undead, so why were they bringing up land now?
What does that mean? Do you want me to develop towards agricultural civilization?
But for the undead, farming is useless.
The undead don’t need to eat or sleep, and dirt is everywhere. It’s better to use bone plates to be comfortable.
This environment has changed so much that I can’t understand it.
Li Ziyu frowned, opened the system and checked the newly appeared soil.
【Xirang】
[Level: Castle Level]
[Category: Special (*Breath of the Dead)]
[Introduction: Xiran, the legendary soil from the beginning of the creation of the world, is a self-growing and self-expanding soil with unparalleled magical abilities. The Xiran of the Dead is a soil that has absorbed and infused a vast amount of soul energy, the aura of death, and the aura of darkness. While possessing the characteristics of the original Xiran, it also possesses other special abilities. The soul fire and bones of the undead buried within the Xiran are nourished by the Xiran, becoming even stronger.]
