Weapon seller in the world of magic

The mage's smile widened upon realizing that the woman was actually willing to sacrifice her life. He didn't waste any time in striking the deal, "I'm willing to go through the Blood oath to the elemental spirits."

"Not a Blood oath, but do a soul oath, Vexiron," replied the Elven High Priestess, not intending to trust him.

There are three types of oaths one can do to the heavens. 

One is the oath of cultivation with the heavens as the witness. Breaking such an oath will incur a lightning strike from the heavens, but it can be avoided when one enters the demigod realm.

Second is the oath of blood to the elemental spirits. Breaking this oath will incur the wrath from the elements of nature such as fire, water, lightning, earth, and wind. The forces of nature keep on trying to kill the oath breaker, but in this process, it can destroy the world too.

The last is the oath of the soul to the heavens. Breaking it will result in the extinguishment of the soul after the death.

It means there won't be any reincarnation and unless one is in God's realm or has a heaven-defying existence like the system, they would have to keep living in fear of death. Not even divine-grade weapons can break those chains on the soul.

Sylvandria can only put her trust in such an oath, making the demigod hesitant a little bit. He was wondering whether he should go with her proposal or just capture her by himself.

But, thinking about his goal, he gritted his teeth and gave a nod as he already knew the extent of her powers, "Alright, I will perform the soul oath but you must do the same."

In the next instant, his words echoed throughout the region, "I, Vexiron of the Void Realm, with heavens as the witness, and my soul as the leverage, as long as you abandon your faith to your gods, become the bride of Eol, the Great, and give birth to a heir, I will free the surviving elves."

Following his words, a seal is shot in the air by his staff before it goes back into him, transforming into a chain over his soul.

After the process was completed, the mage raised his staff once again, "Now, I shall remove the threat as a way to show my sincerity, but I warn you. If you go back on your word, I will not hesitate to conjure up another black hole, which is far more powerful than this one."

The High Priestess nodded with a serious expression, "I keep my word."

The mage let out a smile and looked at the raging black hole that was covering over 10 kilometers in radius. Using all of his ether energy, he shot out a mass of black energy into the sky.

Far above the black hole, another singularity was formed with a mass supposedly far higher than the one Mark accidentally created. Or atleast that was how it appeared at first glance as it affected the range of more than 100 kilometers around it.

"What are you doing?" Sylvandria frowned at him. Shouldn't he take it back? Why was he making it worse?

Vexiron answered, "The earlier one also absorbed your divine energy, High Priestess Sylvandria. I can't dismiss it using traditional means. The bigger one will suck the smaller one before I set it into an explosion."

"Okay." The High Priestess nodded in understanding and raised her head to look at the scene.

However, the reality was completely different from what they thought.

Not even Vexiron expected his black hole was move toward Mark's black hole instead of the other way around.

In a normal scenario, they should pull each other with their gravitational force and orbit around each other before the smaller one gets swallowed by the bigger one eventually.

However, the black hole created by Vexiron just zoomed into Mark's creation without showcasing any resistance or so whatever, shocking both of them.

"How is this possible?" Vexiron just stared at the formation of a massive black hole, which now started to pull everything within a 500-kilometer range.

Along with the mountains and everything, Sylvandria started to get pulled toward the black hole. "You monster… I curse you…" She roared in anger as she was trying her best to resist the gravitational pull but it became too strong for her. Even Vexiron himself is barely resisting it with an energy barrier over himself.

Meanwhile, somewhere above the forest, Mark was seen flying at blazing speeds. Upon seeing everything go dark all of a sudden when the sunrise just happened, he stopped flying and turned around. In the sky, a majestic black hole, spanning tens of kilometers, was absorbing everything in its range. 

Upon seeing how close its effective radius got to him, Mark's face became paler. "How did this get so big? I need to hurry up."

He turned around once again and started flying toward his destination.

Back to Vexiron and Sylvandria, the former no longer looked in great condition while the latter was struggling to escape the gravitation pull. She was moving at a pace of ten meters for every second, giving her a maximum of 20 minutes of survival.

Because of the swirling violent winds and huge rocks and trees as objects, her voice wasn't even reaching the mage, who still looked in a daze and panic.

"What to do? What to do… At this rate, everything is going to fall apart. I need to do something…" Vexiron gritted his teeth while taking out some sort of scroll from his storage ring, "I guess I was left with no other choice. Lord Xalazar is my only hope."

He was about to pour his ether energy into the scroll to activate it, but before he did that, a familiar voice was heard in the surroundings. "Don't bother, Vexiron of the Void. I'm already here."

"Eh?" The mage looked around before sensing a strong presence quite near the black hole but wasn't affected by its gravitational pull.

At one glance, he looked like a human, except for two horns on his head. The stranger raised his hand, releasing pure demonic energy from his palms.

Sensing the power that far exceeded his, Vexiron became elated in an instant, "The power of an immortal. Now, the problem will be solved for good."

However, his happiness was short-lived as the beam of demonic energy sent into the black hole only increased its power by ten times instead of destroying it.

"Kyaaa…" The High Priestess couldn't help but scream as she started flying toward the black hole at an increased pace. Even the mage was no longer able to protect himself anymore.

Fortunately, he was someone who had a gravity attribute and also a demigod to add. He was able to escape the influence of gravitational pull and made his escape while cursing the idiot who made it worse.

In the vicinity of the black hole, the stranger, who appeared to be unaffected by it, let out a deep sigh, "No one under the Saint realm can diminish it. This world is doomed for good. I guess I have to look for another world." He disappeared from the spot, and went to god knows where.

Meanwhile, the entire forest and the elves inside it started to fly in the sky. Due to the sudden increase of the range, several trees and rocks came at him at once.

But, just as he was about to be struck by them, everything came to a standstill. The black hole, the flying trees, rocks, huge volumes of water, elves, demons, Sylvandria, Steve, James, and even Vexiron were frozen in their spots. 

The only person that was unaffected on the planet was Mark. However, even he wasn't himself at the moment.

His eyes turned pitch-black and there was a mystical orb in his hand. He lets out a deep sigh as he mumbles in a robotic high-pitched voice like a female A.I., "What a troublesome host that I got. Because of this fool, I exposed myself to those gods and I even have to use the object from the future as a tool to protect the present. If only he had chosen the time attribute like I suggested instead of going with anti-matter, this would have been a piece of cake. Let's hope this incident will serve as a catalyst."

The orb then glowed in bright green, instantly returning everything to back it was, before the emergence of the first black hole. 

The time continued to move on while Mark lost consciousness and started falling from the sky.
