There was no black dragon in the hall of the dragon's lair, but a humanoid creature wearing a black robe with a face hidden in a hood, its right hand holding a staff like a spine bone, and its left hand in the robe, in the shadow of its hood, revealing two scarlet gazes.

"Who the hell are you?" Song Jian asked loudly.

"Aren't you looking for the Dark Lord, I'm the Dark Lord here." The humanoid creature opposite Song Jian was tumbling with a rich undead aura, which had condensed into substance, constantly changing, and human faces struggling in pain appeared one after another, and they continued to let out a silent roar towards Song Jian around its body.

"The Dark Lord?" Song Jian was stunned for a moment, and couldn't help but ask, "Isn't the Dark Lord a black dragon, how could it be you?" ”

"Black Dragon, Boom, are you talking about it?" With a wave of his right hand, the humanoid creature revealed a huge dragon head from the top of the nest hall, which was a huge black dragon, but what appeared in front of Song Jian's eyes was the corpse of a black dragon, which was originally supposed to be a dark golden vertical pupil, but now it also exudes a scarlet light, the flesh and blood are dry, the skin and dragon scales are flashing with a layer of rusty dark red, and many places have rotted, revealing the white bones inside.

"Corpse Dragon ......" Song Jian's heart sank, the previous third-level undead castle, the corpse witch lord there had always dreamed of creating a corpse dragon, but under Song Jian's attack, it failed, and until the end of the war, there was no corpse dragon.

But now, a huge corpse dragon appeared in front of Song Jian's eyes, and it was made from a powerful adult black dragon.

"The adult black dragon is a seventh-level class, although it has lost its sanity and self-consciousness after making it into a corpse dragon, the dragon's magic can't be used, but the physical strength has reached a higher level, and more importantly, those hearts and heads that are Achilles' heels for creatures are not weaknesses at all for a corpse dragon." Song Jian said secretly in his heart.

An adult black dragon and a corpse dragon are enemies for Song Jian to choose, and Song Jian can choose an adult black dragon. Although the rank of the corpse dragon is the lowest among the seventh-level troops, its combat effectiveness can at least rank in the top three.

"You killed the black dragon here and made it into a corpse dragon?" Song Jian was surprised.

"Jie Ji, speaking of which, I was able to successfully make such a corpse dragon, and I have to thank you, if it weren't for you destroying that third-level undead castle and letting a baby corpse dragon escape to me, I'm afraid I wouldn't have been able to research out how to make a corpse dragon...... The Dark Lord let out a happy smile.

As he spoke, a young dragon jumped out and stood beside the Dark Lord, this young corpse dragon was the one that escaped from the castle of the dead, it hid under the thick foundation of the castle of the dead, and waited until Song Jian left before it came up from the ground.

Originally, it was born in this dragon's lair, and after becoming a corpse dragon, because the undead corpse witch had died, it also regained its freedom, and with some fragments of memory, it returned to this dragon's lair.

As a result, he was captured by another corpse witch who had just occupied the place, and became a slave of this corpse witch through a contract, and it was through its body that the corpse witch studied how to make a corpse dragon.

"It's a pity, if you can destroy that castle of the dead sooner, then I can have two corpse dragons, instead of just one and the other half-finished like now." The Witch lowered his hood, revealing a skeletal head.

Boom, boom~

After a loud bang, the skeleton of a giant dragon slowly came out of the shadows, this skeleton did not have a trace of flesh and blood, the whole body was gray bone, and a clear crack could be seen in the bone of its right leg.

"This is the Dark Lord in the mouth of those flower elves before, an old and aging black dragon, I have studied countless ways to make a corpse dragon before, but I have not succeeded, so this dragon corpse has suffered too much damage, and it is a pity that I can only make a bone dragon......" The corpse witch shook his head and let out a sigh.

At this time, the corpse witch, as if it had obtained a new toy, couldn't help but want to show off to others, its mouth said pity, but it showed a smug look, staring at Song Jian's face, wanting to see a look of horror and despair from above.

But soon, it became disappointed, and Song Jian had a blank expression on his face, as if he was not moved at all.

The bone dragon is only a sixth-level class, whether it is magic or physical strength, it is far from being comparable to an adult dragon, the only desirable thing is that it inherits the hard bones and dragon power of the dragon family, and has a certain degree of bonus effect on other creatures, at the same time, it can also spit dragon breath, but the dragon breath at this time is completely condensed by the energy of the undead, and does not have the hot temperature and burning effect of dragon breath, but has a strong corrosive effect, and the power is worse than the real dragon breath.

"A sixth-level bone dragon and a seventh-level corpse dragon, are these all your hole cards?" Song Jian said coldly.

"And me, the master's most loyal servant, the ghost Karui, giggle~" The flower spirit soul next to Song Jianjian suddenly flashed and appeared next to the corpse witch, returning to its original appearance, a mass of black-gray shadow creatures.

"I have long felt that you have a problem, but I need you to lead the way, so I haven't exposed your ......" Song Jian stared at the ghost that was constantly floating up and down in the air, and said lightly.

"Human, you are cornered, why don't you surrender to me and let me transform you into an immortal undead creature and become an undead hero?" The Corpse Witch laughed awkwardly.

Click~

Behind Song Jian, a large group of undead warriors appeared, blocking all the passages, these are all advanced skeleton soldiers comparable to second-order troops, and they are the most favorite cannon fodder classes of undead heroes.

"You are the stupidest human hero I have ever seen, you dare to come to the dragon's lair alone, even without me, your fate will not be much better, well, my patience is limited, you have three seconds to consider my previous proposal......" The corpse witch said coldly, the staff in his hand had begun to bloom with gray light.

"If you're willing to be one of my undead heroes, then I can consider sparing your life!" Song Jian said calmly: "But I believe that if I don't dismantle your two big toys, you won't consider my suggestion, so I will be very kind to ask you again after killing your two big toys." ”
