The Black Knight flew into a rage and fought with all his might.
The intelligence of the Undead Knights under his command was equivalent to that of a human teenager. For dragons and other highly intelligent races, such intelligence was not high, but their battle intelligence was impeccable.
Coupled with their keen instincts and innate skills, the Undead Knights quickly assessed the opponent's weakness based on the size of the Black Dragon's body. They sent out a few knights to harass the Black Dragon from the flanks, while trying to send someone to attack from behind the Black Dragon.
A big head, thick neck, and strong body would bring about a more ferocious aura, but this Black Dragon that looked different from other true dragons also had a fatal weakness that could not be ignored, and that was that it could not directly attack the enemy behind it — at least according to common sense, this was what the Undead Knights judged.
The Black Knight, Negendro, began to make arrangements. He led more than ten Undead Knights to face the Black Dragon head-on, while at the same time, he got someone to go behind it and attack from the blind spots that the Black Dragon could not see. There were even knights who chose to abandon their skeletal horses and jump behind the Black Dragon to assassinate it.
They succeeded.
At the end of the day, Caesar was still a living creature and not a pure war machine. In the face of a joint attack from many directions, it was inevitable that it would be careless due to its distraction. Unknowingly, an agile Undead Knight had already jumped on its back.
Seeing this, Negendro's heart settled. The strength of the Black Dragon Lord was beyond his imagination. Until now, he had already lost seven Undead Knights and countless strengthened skeletons and gargoyles that assisted in the attack. However, the Undead Army still did not pose a substantial threat to the Black Dragon.
As a highly intelligent Undead, seeing such results, the Black Knight could not help but feel anxious and even discouraged. But now, the battle was about to reach a turning point. They had found the Black Dragon's Achilles' heel, and there were Undead Knights riding on the Black Dragon's back.
This dragon looked like this. Other than that tail, it did not have any other means to attack the enemy on its back.
Negendro concluded.
The Undead Knight jumped onto his back and raised his sword. His movements were as fast as lightning as he swung his sword down, hitting the Black Dragon's back.
It purposely avoided the cuticle that had been tested to be as hard as iron. Instead, it landed squarely on the Black Dragon's crystal-like thick and shiny scales. Sparks flew everywhere.
The sword did not have any effect. It only managed to cut through the thick scales on the Black Dragon's back.
But it didn't matter. They had already found the Black Dragon's weakness. There would be a second strike, a third strike … Negendro thought.
"Please be careful, true dragon."
He quickly moved to Caesar's side and cast a defensive spell with little effect on the Black Dragon Lord. "Wind Wall."
This was the first time she was so close to the Black Dragon. Before this, the Black Dragon Lord seemed to be wary of her. Hence, Angra had been very careful, afraid that the other party would notice something was wrong. She did not even dare to approach intentionally and always kept a distance.
But it was different this time. Taking advantage of the Undead Knight's attack, she had already floated to the upper right side of the Black Dragon Lord. She was within reach.
And just as everyone present had their own ulterior motives, Caesar finally felt something strange behind him. He muttered and prepared to eliminate the threat behind him first.
The solution to the problem was simple. It was to turn his head and exhale.
This was not the usual turn of the head. Instead, it was a 180-degree turn of the neck. This was very easy for the Black Dragon who had an autonomous control unit. As his bones creaked, Caesar directly turned his entire head to his back.
At this time, the Undead Knight was still attacking the Black Dragon Lord's back with all its might. When it looked up, it saw two scarlet vertical eyes — the Black Dragon was looking at it.
The Undead Knight's soul fluctuations became intense. Its intelligence was not high, so it could not figure it out for a while. Didn't it jump behind the Black Dragon? How did it appear in front of it?
Before it could figure out what was going on, it was drowned in surging flames and evaporated in a blaze.
"This is … a monster!"
Negendro was deeply shocked. For Caesar, this was a normal operation, but for the Undead, it was unacceptable. Among the true dragons, there was no dragon that could do this!
It actually turned its neck straight back!
Wasn't this a move that could only be done by Skeletal Dragons?
"Chance!"
At the same time, the Calamity Dragon, whose brain circuit was completely different from other creatures, had a different idea in its mind. For the Calamity Dragon, this was the Black Dragon Lord's real mistake. In order to fight against the Undead Knight, it had finally neglected itself.
And now, Caesar was within its reach.
He would never let go of such an opportunity. In an instant, she removed the transformation spell that restricted her body and returned to her dark and gloomy appearance of the Calamity Dragon. Her sharp claws gleaming with cold light directly pierced into the Black Dragon's body.
The Calamity Dragon was best at curses and all kinds of poisons, so in a fraction of a second, using her claws as a medium, blood toxins, neurotoxins, and all kinds of mixed curses all swarmed into Caesar's body in an instant.
"It's done!"
Angora was certain. The Calamity Dragon was a rare and special dragon species. Its body was weaker than all the other Pentashade dragons, but its curses were stronger than the Black Dragon's, and its poisons were stronger than the Green Dragon's. So when these two spell-like abilities were injected into the Black Dragon Lord's body, Angora subconsciously felt that the situation was set.
Next, he just needed to wait for the various poisons and curses to take effect, forcing the Black Dragon to sign a contract with him under the torture of the poisons, the invasion of the curses, and the threat of death.
"Praise be to you, great Night Dragon Pharazul."
Angora had already begun to pray for a response from the God he believed in and prepared to form a contract. At the same time, he pulled back his claws.
However …
He couldn't pull them out.
"???" Angora was stunned, but at the same time, he increased his strength.
But he still couldn't pull his claws out of the Black Dragon's body. There seemed to be a pair of shackles in his body that tightly shackled him.
At this time, the Black Dragon's head that had turned away slowly turned back to look at the Calamity Dragon.
Unexpectedly, Angora didn't see any shock, panic, or fear in the Black Dragon's eyes. There was only calmness in those deep red vertical eyes, like a bottomless abyss.
"What's going on?"
Angora felt that something was wrong, and immediately felt a strong sense of uneasiness. She wanted to pull her claws out as soon as possible and escape to a safe place before investigating the sudden abnormality.
But no matter how hard she tried, her right claws couldn't move even an inch.
"I warned you."
Caesar looked at her. "But you forgot."
Before he could finish, Caesar had already grabbed Angora's neck with his hand and at the same time loosened the muscles that locked him down, allowing the Calamity Dragon's right claws to break free and lift the True Dragon up.
The Black Dragon was standing on two feet, so Angora's limbs were completely off the ground. In stark contrast to the huge and fierce Black Dragon, she looked thin and weak.
