Weapon seller in the world of magic-Chapter 561: Mark acquires a demon slave

'It looks like I struck gold.'

Mark controlled his happiness by clenching his fist and trying to be as calm as possible as he replied, "Bael once told me about the existence of a beast named Leviathan. I wish to form a contract with it. But, I don't know its location and I don't have enough time to explore this entire realm in search of the beast. If you kindly help me, it would help me a lot."

"Guardian Leviathan?" The demon's eyes widened in shock before a chuckle escaped from him, turning into a burst of laughter, "seriously? Hahaha… oh, great devil… I never thought I would hear such words from a mortal in my whole life. You looked like someone who is still in the Body forging stage (<demigod) and you want to form a contract with the Great Leviathan? Hahaha…"

"Guardian?" Mark was taken aback by the demon's address toward the beast. He felt like the beast he had to face was something that was more powerful than this Saint-realm demon lord. At once, he felt like he should use the amulet and escape this place.

But, remembering his promise, he calmed down his nerves with a deep breath and nodded firmly, exuding confidence outwardly, "I think I can do it, as long as I have help."

"Help? Bael is considered one of the top three fighters in this realm and not even he is a match for the guardian," replied the demon. After a brief pause, he turned serious and added, "Return to your world, mortal. You are lucky that you are in my region, or else, you would have long been shredded into pieces.

The demons don't like mortals and neither do they care about other demon kings in their territory."

'Stronger than Bael? Is it in True God realm (14-circle)?' Mark's facial expression turned ugly, 'In that case, I don't think it is possible for even Chang'e to save husband's soul. Hmm… wait a second. It could be possible with Unnamed. The box weighs over 1.32 billion kg. If I unleash Gravity Dome to the max, its weight will be increased to 264 billion kg.

Now, the target is a 14-circle realm beast. To injure it, I should atleast need force equivalent to that realm.

Let's see… Song Missile with a warhead of 42KT yield releases around 174 Tera Joules, which is equivalent to an attack from an immortal (11.1 stats).

Then, The Mark-14 Nuclear bomb with a yield of 6.9 Megaton releases around 28.9 Peta joules; and that is equivalent to an attack from a Saint (12.1 stats).

So, that means the energy released from an attack of a Saint is roughly 165 times bigger than that of an immortal. I can't calculate it linearly but for a rough estimate, the bare minimum needed to hurt a 14-circle realm should be 1 Zeta joules. We might even be 10 times the value but let's assume this bare minimum value.

Let's say I throw it down from 1km of height. Throwing horizontally requires more work. Not to mention, there is always a risk of failure.

The gravity here in the netherworld is around 16.32 m/s2, according to Ark.

But, what if I apply density manipulation on the object? Its mass will be increased up to 200 times. So, its overall weight will be increased by 40,000 times. Ah, nope. Don't forget that base gravity is different here. it is 1.6 times higher. freewёbn૦νeɭ.com

So, the resulting weight will be 84.48 trillion kg."

"Ark, calculate it for me. Assume the required energy release is 15 zeta joule."

*Ding! That will be around Mach 126 approx, the required velocity needed to achieve the result."

"Eek. that is impossible."

"Ark, reduce it to 1.5 Zeta joule then."

*Ding! That will be around mach 40 approx, the required velocity needed to achieve the result."

"Oh, boy... Mach 40, huh? Hmm... I guess, that is also achievable." Mark nodded. Mach 40 sounds like a huge number but with the help of the divine throne, Mark felt like he could do it.

As the object was bound to his soul, he didn't feel its weight even under any gravitational force. Hence, he was confident in inflicting even greater damage as long as he could just throw it with everything he got, provided that it hit the target.

But the only problem is that this attack should be done discreetly. He needs someone to take away the attention from the target.

As Mark returned to his senses, he saw the demon had already returned to his practice, thrusting his demonic spear into the air.

Mark got an idea.

"Uhh… excuse me," Mark interrupted his practice once again. As the demon looked at him, this time with a slightly annoyed expression on his face, Mark said in a calm manner, "Earlier, you said that you wouldn't like to form a contract with humans for their selfish desires, but I also know that strength is everything in the demon world."

"Yes, so?" The demon furrowed his brows, not liking what this conversation was going to do.

Mark then summoned his divine throne and transformed it into a submachine gun with a thought in his mind, "I would like to challenge you for a duel with my soul as the stake. You win and you may claim my soul; I win and you form a contract with me. Do you dare to accept?" He purposely raised his voice in the end, trying to provoke the arrogance of the demon.

"So, this divine artifact is the reason for your arrogance?" The demon instantly responded with the bottom end of the spear slamming onto the ground, "A foolish mortal who doesn't like to appreciate my noble intentions deserves to die." His demeanor changed instantly. The demonic aura erupted from him, forming a layer over his skin.

Raising the spear and pointing it at Mark, the demon said, "I, Alloces, one of the Great Dukes of Ars Goetia, accept your challenge. If you could win against me, I will even be willing to be your slave, do your bidding for the next hundred years."

*Ding! Information about the target has been updated.

'Man, that was even better. I guess it was the luck points,' Mark nodded with a smile, pointing the gun at the target.

Just as the demon lord was about to make his move, Mark's eyes turned icy blue as he mumbled, "Freezing Gaze, Activate."

Alloces only moved one step and he was frozen on the spot, imprisoned in ice. Mark didn't wait for the enemy to get out; he put away the gun and charged forward while unleashing another skill, "Thunderblast."

*Rumble*

Dark clouds gathered in the sky within a second, followed by the rumbling of thunder, and the descent of yellow-colored lightning, striking the demon directly on his head.

A few seconds later, as the ice melted down, Alloces was found standing there on the spot, with his burnt hair and blackened face, and second-degree wounds on his body.

*Thud*

He fell to his back at once.

"Uhh…" Mark stood there in a daze, watching the mighty demon falling unconscious in an instant, 'that was an overkill? I thought he was a peak-stage Saint Realm demon.'

*Ding! Master, the target was frozen in ice, which slowed the movement of molecules in his cells. As a result, the cellular energy, which is the prime source of demonic energy couldn't properly defend the body. Meanwhile, the lightning strike as well as the Ice were both conjured by the master. Hence, they didn't go against each other.

However, when the lightning strike hit the target, the resulting energy and the target's fire attribute energy melted down the ice, which turned into water, further helping the remnant lightning energy to inflict more damage on the target.

'Oh, never knew that this combo could have such an effect,' Mark was pleasantly surprised by the result of the combo he merely created on a whim. He thought of freezing the target on the spot, which could give him the time to inflict damage with the Thunderblast that only has the power of an intermediate-stage Saint Realm expert.

If there wasn't the artificial intelligence that scanned the process and explained it to him, he wouldn't have known as everything happened in just a matter of few seconds.

"Well, let's wait then."
