Weapon seller in the world of magic

With no way out of the divine prison and not being able to bear the pain instilled by the needles brimmed with divine energy, the demon emperor Eol was forced to ignite all of his cells and went with a suicidal attack.

His body exploded and released powerful demonic energy that could only heavily crack the barrier due to the sheer dominance of divine energy over an evil attribute like demonic energy.

Seeing that there was nothing but blood spilled inside the barrier, she dismissed her technique and let out a smile of satisfaction, "Okay, my job is done here. I hope whatever you are planning will turn successful too, Mr. Lu." She mumbled to herself, rekindling her hopes on the human as she realized that everything he had done so far was a giant ploy to defeat the enemies.

Little did she know that this timely ending of her battle would indirectly affect Mark's choice.

Back in the wilderness, Mark was thinking about how to negotiate the terms with the system despite the fact that he thought it was worth integrating the factory in his mind with the real world even if he had to give up the suit. It is not like this celestial-grade suit will be of any use to him in battle.

However, after spending months with the system, he knew that in a deal, he should never accept what the system has to offer.

Just as he was wondering what to ask, Sylvandria's battle came to an end and his mission became a failure as a result.

*Ding! Eol's physical body was destroyed without a trace. Quest "Save Eol" is failed.

*Ding! You receive a new emergency quest, Resurrect Eol.

Quest: Resurrect Eol

Description: With the destruction of his physical body, there was no other way for Eol to revive. The host must obtain the soul that was trapped in a treasure and resurrect him using an inanimate humanoid figure as a host.

Reward: Space station (upgradable)

Accept?

"Rocket launching station disappeared and the system is giving me the Space station? What kind of bullshit play it is playing with me?" Mark was offended at first, but then he thought that he could probably include it in the negotiations as he considered the rocket launching station, not a big reward.

Since he didn't go far with his request, the system also agreed with the new deal, taking away the suit from him alongside the tier-5 bloodline reward and giving him the launching station along with integrating the factory with the real world.

While the system asked him to choose a plot of land to fix the factory and all of its facilities, Mark asked for time. The system accepted it and sent a mystery package to his inventory.

Upon using the mystery package, Mark could place it on flat ground with no objects blocking it and build the factory, which will be upgraded just like the one in his mindscape.

Three days later;

At the royal city of new Sasa Allanor, a city that was named by Sylvandria for the new beginning of the Elves, a throne was placed on a podium and thousands of surviving elves were assembled along with the rescued members of the royal family.

The original heir to the empire, Prince Alvis was still alive but he remained in the bunch while the princess sat on the throne owing to the fact that Mark, the savior wanted her to rule the land.

He never mentioned marrying her or anything, but the royal elves were aware of the prophecy and they automatically assumed Mark would be on Princess Elowen's side. Hence, the royal elders and even the prince accepted his verdict, letting the High Priestess proceed with the coronation ceremony.

Mark wanted to leave for his world as soon as he met with Steve and James, but the princess requested him to stay until the coronation ceremony.

She wants to formally thank his services as a ruler in the form of presenting him with a deed in front of the elders and the citizens. 

This special deed contained an agreement from the elves that he could mine their world as much as he could and anywhere he wanted for the next 999 years. Whether the current ruler gets overthrown by someone else, the agreement still cannot turn void.

With Bael on his side, Mark doesn't need some deed to mine the resources of this planet. However, formally getting the permit will make his job easier as he wasn't the one who was going to mine but his robots. He plans to spread huge amounts of them all over the world and acquire the rare materials.

Since waiting for three more days wasn't a big deal, Mark accepted her proposal and patiently stayed as their guest until the coronation ceremony was completed.

The day had arrived and Mark was also standing along with his three companions and the royal elves on the large platform, watching the High Priestess reciting some strange incantation and the Princess being enveloped by Sylvandria's divine energy.

Once the incantation was finished, the divine energy that surrounded her made its way to her head, gathered to become a single ball of light before it transformed into an exquisite-looking crown.

"As the High Priestess of Ixitus Empire, I hereby announce that the coronation ceremony has been completed. Subjects of the Ixitus Empire, kneel to your ruler. All hail Queen Elowen."

Everyone except for the High Priestess, Mark, James, and Steve knelt down at the same time and cheered, "All Hail the Queen." As a citizen of the Ixitus Empire for a few years and still considers herself a citizen, even Zan Rong followed the same as others.

With a smile on her face, Elowen Silverleaf then rose to her feet and spoke, "Before I address the public, I wish to thank a special person who made this all possible." Several gazes fell upon Mark.

"If she wasn't going to return here, our Savior would have never come to our world. On behalf of all the citizens of the Ixitus Empire, I would like to say thank you to Marina Zan and present this treasure as a reward," Elowen took out an artifact that looked like a fist-sized diamond

The royal elves started murmuring among themselves, the majority of whom agreeing that it is too precious and some were wondering when such a diamond existed in their treasury as they never saw it before.

Mark didn't care at first as it was just a diamond and he was just trying his best to not show his impatience of getting his reward and returning to his world, but then, as Zan Rong stepped forward and took the diamond in her hands, James raised his voice and this gained his attention. Of course, everyone's too…

"Ms. Zan, throw away the diamond. There's something wrong with it," shouted James as he rushed forward. Surprisingly for him, Steve firmly caught his arm with a serious-looking expression.

"What are you doing?" While James asked him, Mark activated his Eyes of God skill and inspected the green-colored diamond that started glowing in Zan Rong's hand.

*

Cursed diamond of Vexiron

Description: A cursed artifact created by mage Vexiron. Apart from its master, those who touch it will get trapped inside. 

Note: It only works on those with cultivations below 10-circle. Destroying the artifact will kill the prisoners too.

*

By the time he read the details, a powerful suction force erupted from the diamond and absorbed Zan Rong in an instant.

Amid the surprised gazes of the spectators, the princess started laughing as she picked up the diamond, "foolish little human…"

"Your Majesty?" The High Priestess was shocked at Elowen's actions. "What are you doing?"

Tilting her head and coldly looking at Mark, Elowen spoke, "Do you really think you have killed me, human? Whatever you saw was nothing more than a grand illusion created by me."

*Ding!
