The Black Knight was furious and fought with all his might.

The intelligence of his undead knights is about the same as that of a juvenile human, which is not high for dragons and other highly intelligent races, but their combat intelligence is impeccable.

Armed with keen instincts and innate skill, the undead knights quickly assessed their opponents' weaknesses according to the size of the black dragon, and they divided several knights to harass them on the flanks, while attempting to send people around behind the black dragon to attack.

It is true that a large head, a thick neck, and a strong and large physique make for a more ferocious imposing, but this black dragon, which looks very different from other real dragons, also has an Achilles' heel that is hard to ignore, and that is that it cannot directly attack the enemies behind it - at least according to common sense, the undead knights judge it this way.

The black knight Naldero began to arrange, and he led more than a dozen undead knights and the black dragon to face it, and at the same time let people turn behind it, attacking from the blind spot that the black dragon's sight could not take into account, and even some knights chose to simply give up the bone horse and wanted to jump behind the black dragon to launch an assassination.

And they succeeded.

At the end of the day, Caesar was a living being, not a pure war machine, and before he knew it, an agile undead knight had jumped on his back in the face of a multitude of multi-faceted attacks, and negligence due to distraction.

Seeing this, Naldero was sure that the Black Dragon Lord was stronger than he imagined, and so far, he had lost seven undead knights, as well as countless enhanced skeletons and gargoyles that assisted in the attack, however, the undead legion still failed to pose a substantial threat to the Black Dragon.

As a high-level undead with wisdom, seeing such a result, the black knight was inevitably a little anxious and even discouraged, but now the battle is about to usher in a turning point, they have found the black dragon's death hole, and an undead knight has ridden the black dragon's back.

The dragon looked like this, and apart from its tail, it had no other means of attacking the enemy on its back.

Naydro concluded.

The undead knight who jumped on his back raised his long sword, his movements were as fast as thunder, and a sword slashed straight down, slashing at the black dragon's back.

It deliberately avoided the hard-as-iron cuticles that had been tested, and slashed at the black dragon's crystal-thick, shiny scales, and the flames burst out.

A sword didn't work, it only cut through the heavy scale armor behind the black dragon.

But it doesn't matter, they have already found the weakness of the black dragon, and then there is a second sword, a third sword...... Naydro thought.

"Please be careful, true dragon."

Angela whispered, quickly leaned over to Caesar's side, and cast a defensive spell for the Black Dragon Lord with little effect: "Wind Barrier." ”

This was the first time she had been so close to the black dragon, and before that, the black dragon lord seemed to be wary of herself, so Angela had been cautious, for fear that the other party would notice the abnormality, and she didn't even dare to approach intentionally before, and always kept her distance.

However, this time was different, taking advantage of the undead knight's attack, she had already floated to the upper edge of the Black Dragon Lord's right side, reaching a distance within reach.

And just when everyone in the audience was pregnant with ghosts, Caesar finally felt the strangeness behind him, and he muttered, ready to wipe out the threat behind him first.

The solution to the problem is simple – just turn your head and breathe.

This twist of the head is not a turn back in the ordinary sense, but a hundred and eighty degrees of twisting the neck, which is easy to do for a black dragon with an autonomous control unit, and Caesar twists his whole head directly behind his back in the sound of bone creaking.

At this time, the undead knight was still attacking the black dragon lord's back very hard, and as soon as he looked up, he directly saw two scarlet vertical eyes - the black dragon was looking at it.

The soul fluctuations of the undead knight became intense, its intelligence was not high, and it would not be able to figure out at all for a while, didn't he jump behind the black dragon, how could he appear in front of it again?

Before he could figure things out, he was overwhelmed by the surging flames and evaporated in a flash of fire.

"It's ...... Monster! ”

Gnadro was deeply shocked, for Caesar it was a routine operation, but it was unacceptable to the undead, and no dragon among the real dragons could do this!

It twisted its neck straight back!

Isn't this something that only a corpse dragon can do?

"Chance!"

At the same time, the Calamity Dragon, whose brain circuit is completely different from other creatures, is stirring up in his brain with an alternative thought, for the Calamity Dragon, this is the real flaw of the Black Dragon Lord, who finally ignores itself in order to fight against the Undead Knight.

And now, Caesar is within reach of her.

Angela would never let go of such an opportunity, and in an instant, she lifted the transformation technique that restricted herself, and regained her appearance as a dark and obscure calamity dragon, and her sharp claws with cold light pierced directly into the black dragon's body.

The Calamity Dragon is the best at curses and all kinds of toxin abilities, so in a ten-thousandth of a second, with her own claws as the medium, the blood circulation toxins, neurotoxins, and even various mixed curses all swarmed into Caesar's body in an instant.

"It's done!"

Angela was sure in his heart that the Calamity Dragon was a rare and special dragon species, its body was weaker than all the five-colored dragons, but its curse ability was stronger than that of the black dragon, and its toxin ability was also stronger than that of the green dragon, so when the two kinds of spell abilities were injected into the body of the black dragon lord, Angela subconsciously felt that the overall situation had been decided.

Next, just wait for the various toxins and curses to take effect, and let the black dragon be tortured by venom, cursed infestation, and death threats, and forced to sign a contract with him, and everything will be done.

"Praise be to you, great night dragon Farrazur." Angela had begun to pray for the response of his gods, preparing to form a contract, and withdrawing his claws.

However......

Can't pull it out.

“？？” Angela was stunned, and at the same time increased his strength.

However, she still couldn't pull her right claw out of the black dragon's body, and there seemed to be a shackle in the other party's body, cuffing herself to death.

At this time, the black dragon's turned head slowly turned back and looked at the calamity dragon.

Unexpectedly, in the eyes of the black dragon, Angela did not see shock, panic, fear and other emotions, and there was only calm in those dark red vertical eyes, like a bottomless abyss.

"What's going on?"

Angela felt that something was wrong, and immediately felt a strong uneasiness, and she wanted to pull her claws out as soon as possible, first get out of the way and get out of the way to a safe position, and then check the sudden abnormality.

However, no matter how hard she tried, her right paw could not move for half a minute.

"I warned you."

Caesar looked at her, "But you forgot." ”

Before he could finish speaking, Caesar had already pinched Angela's neck with his backhand, and at the same time let go of the locked muscles, allowing the Calamity Dragon's right claw to break free and lift the real dragon up.

The black dragon stood on two legs, so Angela was pinched so that his limbs were completely off the ground, in stark contrast to the large and fierce black dragon, which appeared thin and weak.
