171 Killing Ao Yun, Undead Servant Effective (2)

Seeing this, Yuna, who was behind him, did not hesitate at all. She directly bit her lip and spat out a dense blood essence.

As she spat out this mouthful of blood essence, Yuna's face instantly turned pale, and her expression directly withered.

However, Yuna did not waste any time. She directly used her dark power to envelop the blood essence in her hand.

The blood essence in her hand instantly transformed into a dense dark power that enveloped her and Lu Yan's bodies.

Thick black trees spun out from the ground and quickly climbed up Lu Yan and Yuna's bodies, directly enveloping them.

The flames Ao Yun spat out landed on the black tree, instantly roasting the bark. However, the black tree isolated a large number of flames, preventing Lu Yan and Yuna from being injured by the flames.

Ao Yun looked at the black trees that surged out in front of him, his eyes revealing hidden hatred.

The last time he captured this dark elf princess, she did not know anything. Now, she already knew how to mobilize so much power. How detestable.

Ao Yun's body quickly rushed out and he directly arrived in front of the black tree. The flood dragon claw in his hand directly grabbed towards the black tree.

Although the black tree could block the black flames spat out by Ao Yun, it was quickly broken in the face of Ao Yun's direct attack. Lu Yan and Yuna were about to be exposed.

Lu Yan raised the Black Bone Scythe in his hand and summoned two bone dragons. The two dragons rushed towards Ao Yun.

At the current moment, the two bone dragons could still cause damage to Ao Yun, but Ao Yun did not care and continued to attack the black trees in front of him.

The power of his blood essence could not last long. It was as if he was slowly dying.

Ao Yun knew very well that he had to kill these two guys before the power of his blood essence was exhausted!

In the sky, the Thunder Emperor Beast looked at the battle below and narrowed its eyes.

The combat strength of that dark elf has increased a lot. Its performance has exceeded its expectations.

However, the Black Flood Dragon actually still had the power of blood essence and had temporarily recovered some strength. This was something the Thunder Emperor Beast did not expect.

"I made a mistake. I failed to take everything into consideration. There's about to be an accident with the show. I have to think of a solution immediately."

The Thunder Emperor Beast thought for a moment and began to use its strength. The surrounding clouds quickly gathered, and this area began to darken.

If a lightning bolt struck, that kid would probably be able to guess something. It had to arrange the proper environment. Otherwise, he would be letting down his identity as a professional actor.

Under the mobilization of the Thunder Emperor Beast's strength, the sky above Lu Yan and the others quickly darkened. Lightning flickered, as if it was about to rain.

"Unfortunately, if I could use some water-type power at this moment and make it rain, it would be even more perfect.

"Lightning is the best I can do now."

The Thunder Emperor Beast shook its head with a regretful expression. Then, a bolt of lightning condensed from the sharp horn on its forehead and tore through the sky before suddenly slashing down.

At this moment, Ao Yun had already broken through the defense of the black tree and had already begun to attack Lu Yan and Yuna.

Lu Yan fought Ao Yun. After a few rounds, the cracks on the Undead Netherworld Armor on his body increased, as if it would shatter in the next moment.

At this moment, a bolt of lightning directly tore through the sky and instantly struck Ao Yun.

Ao Yun's body suddenly froze, and his bones were exposed from time to time by this lightning.

After collapsing onto the ground, Ao Yun looked up at the sky, his eyes filled with unwillingness.

"Damn you!"

In the sky, the Thunder Emperor Beast frowned. "I think I used too much strength, but it doesn't matter. The effect has already been achieved. After this battle, the relationship between these two little guys should improve again, right?"

Below, Lu Yan and Yuna were stunned for a moment. They did not expect a lightning bolt to descend from the sky and directly slash the aggressive Black Flood Dragon to the ground.

Lu Yan did not dare to be careless. He got the two bone dragons and the surrounding undead to go forward and test Ao Yun.

Then, Lu Yan discovered that this Black Flood Dragon was really injured by the lightning and could not move.

Actually, it was not the power of the lightning. It was mainly because this lightning had exhausted the strength Ao Yun had forced out with his blood essence. Therefore, not only did the injuries on Ao Yun's body surge out again, but the consumption of his blood essence also made him incomparably weak.

The two bone dragons and the surrounding undead left wounds on Ao Yun's body, but at this moment, Ao Yun did not move at all.

He stared fixedly at the sky, his eyes already empty.

"Damn, are you kidding me? I give up. Do whatever you want. Perhaps I'll directly reincarnate into a divine dragon in my next life.

"Damn! I just want to become a divine dragon. Why is it that difficult?"

In his intense unwillingness, Ao Yun was directly killed by the two bone dragons!

Sensing the aura on Ao Yun's body dissipate in front of him, Lu Yan heaved a sigh of relief.

After all, this was an epic level demon beast. Even if the other party's strength was damaged to this extent, the other party could still unleash extremely powerful combat strength.

If not for Yuna's black vines and the black trees, as well as the last bolt of lightning, it would be impossible for them to kill this Black Flood Dragon.

However, as long as they succeeded in the end, it was fine!

"Is… is that guy dead?" Yuna looked at Ao Yun's corpse in front of her and said in disbelief.

Previously, she had personally witnessed how powerful this Black Flood Dragon was.

Now that the other party had died in front of her, the impact on Yuna was still very huge.

Lu Yan nodded. "He's dead. His aura is already gone. Don't worry."

When Yuna heard this, her expression suddenly relaxed and she heaved a sigh of relief.

The gloominess from being captured from the Dark Elf Tribe was finally swept away at this moment.

However, in the next moment, Yuna's eyes suddenly widened. She quickly arrived beside Lu Yan and grabbed Lu Yan's armor tightly.

"It! It's alive again!" Yuna pointed at Ao Yun's corpse in front of her, her body trembling uncontrollably.

Lu Yan was stunned for a moment before looking at the corpse of the Black Flood Dragon in front of him. Indeed, he saw the other party's corpse move at this moment.

After being stunned for a moment, Lu Yan revealed a pleasantly surprised expression!

Just now, this Black Flood Dragon was definitely dead. Ao Yun's aura was already completely gone. It was impossible for him not to be dead.

However, now that the other party's corpse had moved, there was only one possibility.

The Undead Servant had taken effect. The Black Flood Dragon in front of him had transformed into his undead!

This was something Lu Yan did not dare to imagine.

Although he had killed this Black Flood Dragon, Lu Yan had never thought that the other party could transform into his undead.

After all, the higher the level and level of the target, the lower the chances of them transforming into his undead.

Be it level or grade, this Black Flood Dragon far surpassed him, so the chances of it transforming into his undead were close to zero.

However, he did not expect it to work when the probability was so small.

At the thought that he would soon have an undead Black Flood Dragon, Lu Yan's expression became excited.

He could not wait to head towards the Black Flood Dragon.

However, after taking two steps, Lu Yan was hugged by Yuna from behind.

"No! Don't go! Let's escape quickly!"

In Yuna's opinion, if they could not kill the Black Flood Dragon in front of her, they were definitely not the other party's match. They might as well quickly escape.

Lu Yan patted Yuna's small hand and smiled. "Don't worry, this Black Flood Dragon is already dead, but it has now transformed into my undead. It's just like the demon beasts you saw me kill previously. It's fine."

Hearing Lu Yan's words, Yuna was stunned for a moment. Since she had been traveling with Lu Yan, Yuna naturally saw some demon beasts killed by Lu Yan revive and become his undead.

However, Yuna did not expect that the Black Flood Dragon in front of her would also transform into Lu Yan's undead.

At this moment, Lu Yan had already arrived in front of Ao Yun. Ao Yun's body had already completely risen, and his eyes suddenly surged with light.
