My World Traveling System: The Harbinger Of Death

Frank kept practicing his magic while conjuring the Spells made through the Gray Magic Skill, an innate type of magic that he had unlocked after forming his Mana Core in Terra. It was certainly a strange type of magic, which he never remembered Gwendolyn ever talked about.

He guessed that it might have something to do with himself, or with his ability to simply use any attribute, gray magic could also mean that it might lack any attribute, and this is why his offensive spells simply were reinforced and pure Mana, and not Mana summoning a special element.

​​

He had to study more his Innate Magic whenever he gets time, perhaps in the World's Gate, which can serve as his 'time chamber' to train Skills and other things while not having to enter a world. After all, although the World's Gate was simply the bridge to other worlds, the space itself was very large, and whenever he was there, the other worlds time would go as slowly as if he were in any of the other two worlds. Meaning that if he were to spend two days there training like a maniac, only an hour would go by in Terra and Earth.

As Frank and Matsuo kept exploring the Goblin's Forest, the Hunting Domain specifically made for newbies, they came across two groups of Goblins, one with three and another with two.

Frank quickly used the spear given by Matsuo to dispose of the group of two Goblins, while Matsuo used his Barriers to stop them from escaping from Frank, despite being monsters with barely any intelligence, they still had basic survival instincts and would run away if they were to meet someone stronger than them that could easily wipe out their groups without much efforts, such as Frank.

Frank quickly figured out how to use the Magic Spear as a Staff as well, generating Spiral Mana Bullets from within the tip of the spear and then throwing them to the targets he desired, the two shrieking Goblins could only do much until they exploded into black smoke, leaving tiny magic crystals behind.

"Grrryarrr!" roared one of the Goblins that Matsuo trapped, moving towards Frank with great speed through a long leap, as it pointed its rusty dagger towards Frank's shoulder!

Frank evaded in time as he felt the foreboding Goblin's presence beforehand, moving away and managing to slip off its attack range and then throwing a large Spiral Mana Bullet right into the Goblin's back!

Boom!

The creature released a small shriek as it turned into black smoke, leaving a tiny crystal behind. The other two Goblins glanced at the scene with both horror and frustration, roaring together as they rushed towards Frank.

Frank decided to charge against them, pointing the tip of the spear towards one of the Goblins' neck, a large river of crimson blood exploded out of the wound as the creature painfully released a last cry, turning into black smoke, alongside the blood that it splattered.

However, Frank quickly felt a slight pain in his right leg as he felt the blade of one of the rusty daggers from the last Goblin pierce through his flesh a little bit. He quickly made the mana flow into his leg as he kicked the Goblin's head with great strength, throwing it away from him and then using the sharp tip of the spear to penetrate the Goblins' head.

Boom!

The creature turned into black smoke as Frank released a sigh of relief, taking out the dagger that was stuck into his muscle tissue and then healing back the wound through Gift of Life. His Mana had become rather large since he acquired a Mana Core, and even though his regeneration ability was outstanding, regenerating two points of Mana per second, he simply needed to wait twenty seconds until his Mana were to be refilled again.

Frank felt the rush of experience points embrace his whole self, but it was not enough, not enough to level up.

"Sigh, how many have been? Twenty already? I wonder how much I can make in Yens with these magic crystals?" asked Frank.

"With twenty Rank 1 Magic Crystals… They're around one thousand dollars each in my clan, so you'll make twenty thousand, which translates to two hundred thousand Yen, or a bit more, Frank," said Matsuo.

"Wait, what?! Really? In this little hour I already made like a five months' salary?!" asked Frank, the amount of money made broke his perception of reality a bit.

"Prepare yourself, Frank, in the underworld that the amount of money is absolutely nothing, to tell you the truth, this sole ring cost me billions of yens, so you'll be working rather hard to even get enough money to buy something useful, even if you think that you made a lot… Well, you can still buy a lot of things that are not magical, I guess. But it is not like it will increase your strength like that, and strength must be prioritized above all in the underworld," said Matsuo.

"That's… I guess you got a point…" muttered Frank, as he glanced at the system notification he recently acquired, congratulating him for defeating twenty Goblins.

Ding!

"I wonder how I can summon the Goblin Champion…?" wondered Frank, as the answer was given right in front of his sight.

Flash!

"Hm? What the- What is going on?" asked Matsuo as he and Frank glanced at their side as countless masses of black smoke, the energy that the Goblins left when they died beginning to gather into a giant mass that began to surpass the four meters of height!

Flash!

The mass of black smoke became thicker and more defined, and within seconds, a green-skinned giant, with a long and sharp nose and ears, bald head, and a horn on its forehead appeared, the creature was packed with muscles and reached four meters of height, glancing at Matsuo and Frank from above as it slowly raised a giant metallic club filled with spikes into the sky.

"GRRRUUOOO!"

Ding!

[The Boss Monster has been summoned!]

"Wait, that fast?! I shouldn't have accepted the rewards immediately…!" thought Frank.

"What is going on? This has never happened before! And this power… this is… a Rank 2 monster!" said Matsuo.

"Let's fight it then," said Frank with a relaxed smile, he was sure that he should be able to fight off the Goblin Champion with his current capabilities, and he was also inspired by the promise of loot after defeating it from the System. He wanted to get as strong as possible to protect himself and his family from the underworld on Earth, while also being able to survive in Terra while he explores the mysterious world there… and of course, to ultimately help Earth recover through traveling to other worlds, who most likely have greater danger levels.

"No, Frank, you're still a newbie, stand back and let me handle this…" said Matsuo with a confident voice, walking in front of Frank. Blades of light emerged from within his golden aura as they began to rotate around him mystically.

"(What's that spell?! It looks awesome!) Wait for a second Matsuo, I also want to gather as much strength as a newbie, let me help you at the very least," said Frank, running around the Champion Goblin who already began to move its metallic club around.

"Sigh… alright, but stand back!" said Matsuo, as he launched three blades of light towards the Goblin Champion at fast speeds, flashing with iridescent lights as they seeped into the giant's flesh and exploded!

Boom!

"GRUUUOO!"

The Goblin Champion groaned in pain, however, the areas that were affected didn't detach nor seemed too wounded, the creature was more resilient, far more for a Rank 2 Monster in Matsuo's mind.

"What? It should have died with that…" said Matsuo with surprise in his eyes.

"Let me help you out, senpai," said Frank, moving near the Goblin Champion and firing two large Spiral Mana Bullets towards the Goblin Champion's head!

Boom!

"GRROOARRR!" roared the giant, walking towards Frank with its large and slow body as it began to pulverize the ground with its metallic club.

"I told you that we should work together, let's take it down!" said Frank, as Matsuo nodded without much of an option left for him.

The Goblin Champion's body was enormous, but it was slow, its attacks were strong, but Frank and Matsuo were fast and nimble enough to evade its rage.

Blades of Light and Spiraling Bullets of Mana flew towards the giant one after another, as it slowly weakened, the giant began to release a tantrum of attacks when it seemingly reached a certain HP threshold, although Frank could not see its HP, he thought that it might have been the case.

"Blades of Light!" said Matsuo, firing more blades made out of light towards the giant as its body began to slowly feel weaker.

"Spiral Mana Bullet!" Meanwhile, Frank fired more spiraling mana bullets and kept his distance from the creature's attacks.

As they evaded its tantrum and threw more attacks, the creature's skin suddenly turned blazing red, as its eyes released fiery flames!

"It changed…?!" asked Matsuo once again in surprise.

"Oh, this is the Boss's last stage!" said Frank, as Matsuo barely understood what he meant.
