Start with an Archangel

The black tide composed of dark cavalry advanced as fast as possible to the vicinity of Obsidian City. However, the planned city gate did not open, and the sounds of fighting and the roar of magic inside gradually became sparse.

No signal of a successful sneak attack on the city gate was sent out, indicating that the black elf assassins failed.

However, in the direction of the plane teleportation array, a soaring magic rose into the sky, and it didn't explode into a shining firework until it was almost close to the top of the cave.

Seeing such a scene, the black elves shouted together, holding their lances high like a forest.

The plane teleportation array leading to Black Iron City was destroyed, which meant that the powerful dwarves were unable to provide support to Obsidian City. The current Obsidian City is an isolated city without enough troops to defend it, but the black elves attacked with all their strength. All the elite black elves in the entire lower cave are here.

This level 13 dungeon is already in the possession of the black elves.

Looking at the Obsidian City defenders on the city wall who had completed their battle preparations, the dark cavalry who rushed to the city in advance did not rush to attack the city wall after seeing that the assassins did not seize the city gate. Instead, they dispersed to both sides to surround Obsidian City.

Another large group of dark cavalry crossed Obsidian City and rushed to the passage to the upper cave. They wanted to capture various garrison locations outside Obsidian City and cut off the connection between Obsidian City and the Iron Hoof Kingdom.

In a short period of time, the cave where Obsidian City is located was filled with galloping dark cavalry, frightening the black dragons who were eager to leave the city to teach the intruders a lesson and retreated into the defense system of the city wall.

As the Dark Cavalry completed control of the entire war zone, the follow-up armies of the Black Elves also arrived one after another.

Black Dragon Fei, who belonged to the black elves, displayed his figure in the air and roared provocatively at his fellow tribesmen in the city. The Spider Queen waves her claws and spits out spider silk that can effectively restrain flying creatures.

The shadow matriarchs restrained their respective clan armies and built attack positions on the spot.

Building materials were unloaded from the baggage vehicles, and the craftsmen worked as quickly as possible to build military camps for the troops to rest and recuperate...

Camp walls, watchtowers, arrow towers, tents, corrals...

The black elves were well prepared to attack Obsidian City. They had both short-term and long-term plans to attack the city... They had no way out and had to capture the city.

Although the Obsidian City defenders were shocked by the sudden attack by the Black Elf army, after all the Black Elf assassins who attacked the city gate were eliminated, the defenders were not too nervous.

This time the black elves did gather a large number of troops to attack Obsidian City, but the defenders knew that the black elves did not have the ability to attack the fortified city. Although many of the troops in Obsidian City were transferred away by the Iron Hoof Kingdom, the remaining troops could still teach the attacking black elves a lesson with their complete city defense system.

Let the nomadic barbarians in these lower caves know... Obsidian City is not the place you should come.

The defenders of Obsidian City were very optimistic about this war. They stood on the tall city wall, bathing in various beneficial conditions. They placed the war equipment used to defend the city where needed, and prepared in an orderly manner, waiting for the invading black elves. A massive attack on the city.

Some garrison heroes even released provocative magic in the direction of the black elf army, hoping to provoke these enemies and make them rush into the long-range attack range of Obsidian City.

But... the black elf's next move made the defenders unable to laugh anymore. Instead, waves of coolness rose from under their feet.

In the camp initially built by the Black Elves, tall siege equipment was assembled, and artillery was placed in front of the Black Elves' military formation. The muzzle of the cannon is facing the city gate to prevent the army from rushing out of the city from destroying the offensive camp being built by the black elves.

The black elves set up six offensive camps outside Obsidian City. All the camps looked like this. An unknown number of heavy siege weapons were assembled really quickly.

The Obsidian City defenders were really scared... How could these barbarians living in the lower caves possess large-scale heavy war equipment? How could they have the ability to produce artillery?

In terms of heavy long-range firepower, Obsidian City's advantage is no longer obvious. They do not have the ability to go out of the city to engage in field battles with the black elves, and the city walls will be exposed to the enemy's siege firepower.

Not only these, but the mobile magic amplification device set up by the black elves in the camp made the Obsidian City defenders feel as if they had fallen into an ice cave.

After the black elf mage settled in, these mobile magic amplification devices opened their magic eyes one by one, and then moved to the front line under heavy guard.

Bundles of magic were released from the magic eyes, and the magic fountain exploded and poured out onto the black elf warriors below.

Feeling the increased strength and defense capabilities, all the black elf warriors let out cheers that shook the cave together... The sound echoed between the cave walls, one layer higher than the other, and actually produced a whistling airflow in the cave.

This is the power of advanced alchemical technology and the power of advanced mechanical manufacturing.

The morale of the Black Elf army rose again and again. On the other hand, the morale of the defenders of Obsidian City quickly fell to the bottom after seeing that the Black Elf had such large-scale heavy siege weapons and alchemy devices.

At this time, a huge black shadow flew up from the Obsidian City Lord's Mansion.

That is the master of this city, Shadow Dragon Muir.

After he received the news that the plane teleportation array was bombed and the city gate was attacked, he quickly learned the news of the black elves' attack, and everything connected in his mind.

In the previous stage, the sudden increase in assassinations in the city must have been caused by the black elves.

Now that the connection between Obsidian City and Black Iron City is interrupted, reinforcements from the Ironhoof Kingdom don't know when they will arrive, and the invading black elves unexpectedly possess heavy siege weapons and alchemy equipment.

Obsidian City has reached the most dangerous moment in its history. Facing the menacing black elf army, as the city lord... he must stabilize the morale of the army immediately, otherwise he will really be doomed.

As expected, the appearance of Shadow Dragon Muir slowly stabilized the somewhat impetuous morale of the defenders. Groups of tauren climbed onto the city wall. These warriors, whose morale was always 1, maintained a strong fighting spirit in any environment.

Wearing heavy armor and holding a battle ax, the tauren are the core of the underground city army. They claim that as long as the tauren are still there, the underground city army will not be dispersed.

Moreover, the dungeon army sequence includes dual long-range units of One-Eyed and Medusa, dual flying units of Harpy and Manticore, and the Black Dragon, which is said to be able to compete with Archangels in terms of individual combat power.

The dungeon army, with its perfectly matched arms, is better at fighting this kind of urban offensive and defensive battle than the black elf army.

As long as Obsidian City can hold on for a while, it can wait for the reinforcements sent by the Iron Hoof Kingdom.
