There was no telling if Angora's spell was too weak or something else, but Caesar did not feel any buffs. He glanced at the half-elf behind him and did not pay too much attention to him, before turning back to look at the high undead that was rushing towards them.
Scan analysis result: Energy construct lifeform.
Overall combat ability verification: 180.
Those were the ability values of Negendro's main fighting force, the Undead Knights. Because they were undead and energy bodies at the same time, the verification values did not fluctuate as usual.
The Undead Knights were considered upper-middle undead creatures. They were few in number at just over twenty, but they were still a formidable force. At least for them, hunting an adult White Dragon or Black Dragon would not be a problem. The Undead Knights were the core of the entire skeleton sea, and also where Negendro's true confidence lay.
Fortunately, although they were energy bodies, they were the most basic construct lifeforms and not amorphous lifeforms. Their body structure was similar to that of a golem, which meant that the Undead Knights would also suffer physical damage — as long as their construct structure was destroyed, they could be destroyed as well.
That was not difficult for Caesar.
The Undead Knights were about a few centimeters above the ground, stepping on phosphorescent flames as they charged.
Caesar actively stimulated the stress hormones in his body. His body, which was originally dark as black steel, emitted a few streaks of scarlet color. His spirit was highly focused as he entered a true combat state.
The Undead Knight took a deep breath, expanding the cavity in his throat to the limit as he spat out weapons, ready to fire.
"Dragon Slayer!"
The Black Knight bellowed. The skeleton horse he was riding was similarly covered in pitch-black armor, revealing only two gloomy eyes. It looked incomparably heavy, but that did not affect the knights' movements. Negendro did not slow down at all, taking the lead as he charged towards the terrifying Black Dragon Lord.
He raised his longsword in front of him. This long and wide greatsword was called 'Howl'. It was taken from the Shadow Pool in the undead domain, and was forged by Negendro with brute force.
Due to the special nature of its material, this sword could be considered a magical weapon. There were shadow elements flowing on it, and due to the inferior forging method, its effect was not outstanding. However, it also had 'cutting' and 'cursing' attributes, so it would not feel good to be grazed by it.
However, before the Undead Knights could come into contact with the Black Dragon, they immediately suffered the first wave of attacks from the opponent.
Strong acid.
This was the Black Dragon's innate ability, Breath. It was also the type that Negendro feared the most. The Black Knight was even more afraid of acid than the raging torrent of flames.
This was because no matter if it was him or the Undead Knights under his command, they were all very afraid of their armor being corroded by the acid. The heavy armor they wore was not an ordinary defensive equipment, but a container.
When the Undead Knights walked out of the Shadow Pool burial ground, they were covered in a layer of dark armor. That was something they were born with. Most people in Airadia believed that, for a body of energy like the Undead Knights, they did not need the protection of armor at all, and that it was purely something they used to scare people.
In fact, this understanding was wrong. Only scholars and experienced adventurers who focused on the study of the undead knew that the main purpose of the armor on the Undead Knights was, of course, not to scare people. Defense was only secondary. The true meaning of their existence was to seal the body and prevent it from interacting with the outside world, thus allowing the knights to achieve the goal of sealing their own energy and preventing it from escaping.
That's right. Scholars viewed these heavy armors as a type of special magical item. This was also the lifeline of undead knights. Their true weakness wasn't their exposed skulls or other bones. Those were only insignificant parts of their bodies. Heavy armor was the true core of these undead knights.
The acid from the dragon's breath would corrode their clothing, causing the armor to be damaged and its energy to leak out. Although this thing could be repaired in the Shadow Pool, the energy that was lost due to the leakage of energy was very difficult to recover.
The dwarf explorer Bismai was right. The higher the level of the undead, the more similar they were to humans, and the more cowardly they were.
Therefore, when they saw Caesar's sour breath, the Undead Knights couldn't help but feel fearful and fearful of him.
God knows where this Black Dragon got so much "saliva." Negendro saw that an overwhelming amount of acid was rapidly gushing out of the Black Dragon's mouth, forming a spectacular dark green flood. This was originally a set of wonders, but now it was extremely dangerous — at least, it was so for them.
However, the Black Knight was, after all, the master of the undead domain. He did not panic and quickly calmed down after a short throb. Negendro slowed down slightly, but he did not stop moving forward, nor did he dodge to the side.
He decisively vibrated his Soul Ripples and gave an order to the undead army.
"Resist."
At this moment, all the liches in the sea of skeletons stopped their spellcasting and turned to the battlefield between the Black Knight and the true dragon. They worked together to build a defensive barrier for the Undead Knights, blocking in front of the acid breath.
At the same time, countless vengeful spirits in the vicinity began to gather and arrived in front of Negendro at an unimaginable speed. They charged in front of the Undead Knights, and in the midst of howls of despair and pain, they consumed a large amount of the dragon's acid breath at the cost of the annihilation of their spiritual bodies.
Soon, the knights escorted by the entire undead army finally arrived in front of the Black Dragon Lord. They raised their swords and sabers, preparing to engage in close combat with Caesar.
However, they were destined for tragedy.
Caesar was not a true dragon in the ordinary sense. He was different from all the dragons in Airadia. This Black Dragon was incomparably powerful in terms of speed and strength. Even the Mother of Poison had to avoid him, relying on magic to suppress Caesar and never letting him get close.
Now, these guys actually dared to charge in front of him, intending to engage in close combat with Caesar.
"Roar!"
The dragon's roar spread through the clouds and cracked stones, like the sound of bronze and steel colliding. Caesar lowered his body, landing on all fours on the ground, and directly dashed out, taking the initiative to plunge into the Undead Knights' weapons. A sweep scraped Negendro back, and at the same time, his tail claw broke through the weak magic barrier and pinched the head of an Undead Knight.
"Bang."
The sound of bones cracking instantly exploded.
The Undead Knight's head was crushed, but to an undead creature with energy constructs, such an injury was not fatal, so the Undead Knight could still move freely even without a head.
They were not low-level skeletons, but warriors who had experienced hundreds of battles when they were alive. They were still strong after death, so the moment their heads were crushed by the tail claw, this headless knight also slashed at the Black Dragon's tail with a backhand.
Sparks flew from the friction, and metal fragments and black scales splashed out at the same time.
Tsk, that hurts.
Caesar thought, and his tail circled the Undead Knight, then stretched out his right claw to hold its body, stared at its body that was emitting faint blue flames, and clawed hard.
A terrifying power burst forth from Caesar's claws, and the powerful pressure caused the armor on the Undead Knight to be pressed into a solid iron ball that was full of wrinkles. The energy body was squeezed out of the body like toothpaste being squeezed out of the body, and it walked towards destruction, returning to the embrace of Mother Earth.
"Punish the evil and eliminate the evil."
At this time, Angora moved closer to Caesar again and provided a supportive buff spell to strengthen the Black Dragon Lord's damage against the undead creatures.
God knows how this guy knew how to use spells to deal with evil creatures. If it weren't for Luna's confirmation and the Battle Lizardmen's confirmation, Caesar might have really thought that he was a genuine half-elf.
(In order to confirm Angora's identity, Caesar specially summoned the Battle Lizardmen who had bought the torches at the time to ask, but their answers were also slightly vague. The Calamity Dragon's disguise was flawless, and the Battle Lizardmen couldn't say anything. They said that it was because they were afraid of the powerful elves.
However, Caesar thought that it was more like the natural suppression of the True Dragon's bloodline, and there was no reason for the Battle Lizardmen to be afraid of the elves when he was present.)
"Damn it, Angora, you actually betrayed me!"
After discovering this detail, Negendro roared a few times in anger. With his wisdom, of course, he couldn't guess what the Calamity Dragon was thinking, but there was no doubt that his former ally had cast a buff spell on the Black Dragon Lord. He saw with his own eyes that the Black Knight was extremely angry.
