Demon Lord's Reincarnation

Nezzard looked at the rampaging undead dragon in the distance and sighed. The undead dragon noticed that its prey had escaped death and quickly found Nezzard that was looking at it. The undead dragon then roared showing its dissatisfaction with the current situation and flew towards Nezzard.

When it was near enough it landed on the ground a few meters away from Nezzard trying to intimidate the yawning Guild Master. Right now Nezzard wasn't wearing any armor only a simple robe and he held no weapon but he looked bored and at the same time confident. Sensing it was being mocked made the undead dragon angrier as it started to charge at Nezzard with its jaw wide open wanting to devour the irritating prey before it.

Nezzard then spoke in a soft voice, but for some reason, it echoed throughout the plains. "[Earth Bind]" Nezzard then snapped his fingers and large vines sprouted from the ground binding the charging undead dragon.

It struggled to release itself from the binding and with its immense strength, it was able to break through some of the vines. But that gave Nezzard enough time to chant and use his strongest spell in his current form.

Nezzard pointed his finger at the undead dragon, and unleashed a low high-end spell "[Heaven's Wrath]." A huge bolt of lightning that was triple the size of what Ren summoned to kill the first prince vassal. The undead dragon was hit by the large bolt of lightning the vines that entangled it was being vaporized, and some of its bones were being charred.

Still, even though it was undead and no longer possessed its former might, a dragon was a dragon, may it be young, undead, or otherwise. It endured the lightning strike and continued its charge towards Nezzard wanting to devour the irritating foe before it.

As it was about to close its jaws and devour its prey, Nezzard sighed as he stomps onto the ground and a magic circle appeared teleporting him behind the undead dragon.

"Even as a young undead dragon you're bothersome, as expected of the apex predator. I can't beat you without unleashing a few of my seals." Nezzard jumped upward as he was talking evading the tail whip of the undead dragon. He then sighed exasperatedly, annoyed by the whole situation.

"This is so beyond my paygrade. That brat and his friends truly bring nothing but trouble." Nezzard then coated his finger with mana and tapped his left forearm and the right side of his neck. After he did this a mechanical voice echoed, "the first seal released, the second seal released."

Once the voice said that a rush of magic power started to gather beside Nezzard. Even the undead dragon stopped its attacks a bit wary of what's to come. Two beings formed beside Nezzard, one was a beautiful lady covered with fire, and the other was a muscular half-naked man that had a gentle breeze circling around him.

"YAHOO! Finally, I've been released! It's been forever!" The flame lady shouted in excitement, while the half-naked guy simply smiled in response. The flame lady then saw the undead dragon and then looked at Nezzard.

"Oh, you finally decided to release this lady queen and you did it in the middle of fighting? You didn't even greet me properly as I was released. You've become truly bold Nezzard. Still, as a benevolent ruler let the spirit queen of fire listen to your excuses."

Nezzard sighed, he simply wanted to summon Kheter the spirit king of the wind, since he was the most agreeable among the spirit rulers, but knowing how strong the undead dragon was, he needed to summon Zoella as well. All of the spirit rulers except for Kheter had irritating personalities, which is why he didn't like using them. Well, it's not like Kheter was any better since he too had a quirk that can't be fixed.

"Cut the crap Zoella! I have no time for your games!" Nezzard shouted as he continued evading the fierce attacks of the undead dragon.

"Hohoho, little Nez finally grew some balls! How about a remove them right now, and get back my submissive Nezzy." Zoella spoke while doing a cutting gesture as she looked at Nezzard's lower region.

"Fine, I promise I won't seal you anymore so help me out please!" Hearing what Nezzard said made Zoella smile sweetly. This man even though he had a contract with the seven spirit rulers, and technically under the contract they needed to listen to whatever he says, yet he still chooses to talk to them in equal terms. This was one of the reasons all the spirit rulers decided to form a contract with this man.

"As expected I really love my little Nezzy." Seeing that Zoella finally agreed to cooperate, Nezzard gave out his commands.

"Kheter stop that undead dragon's movements and don't allow him to escape the area. As for you Zoella, you know what to do." Zheter nodded at Nezzards command, while Zoella smiled showing a fiery glint in her eyes.

Kether placed his right hand onto his chest and then pointed it at the undead dragon. The undead dragon was then surrounded by a torrent of wind. The torrent of wind turned into a dome blocking the undead dragon from moving.

Zoella then placed both of her hands onto the ground and then from underneath the land the undead dragon was standing on, a pillar of fire rose up piercing through the clouds. Nezzard felt a bit dizzy as this was happening.

Being able to summon a spirit ruler might make you look powerful, but they drain a lot of mana from the contractor. If the contractor was weak and had no mana to give, they would have drained his life force instead. Not only do they drain mana, but they also drain the user's stamina, which only makes Nezzard even sleepier after using them.

The undead dragon tried everything in its power to escape the pillar of flames, but being surrounded by that torrent of wind it was unable to do anything as its bones slowly turned into ashes.
