The Goblin's Leveling System!

I had finally obtained Damien Miles' demonic heart and not to mention that the demonic mana he had used was still contained in the demonic heart.

I was in luck to obtain such a useful item.

Now I only needed was to obtain the rest of the archdemon hearts from the other 4 archdemons.

Wait, a fresh body of an archdemon and a fallen hero should be valuable!

I forgot to collect the blood of an archdemon who was formerly a hero.

"Black Hole!"

I cast [Black Hole] and precisely controlled its suction force and stored all of the blood that was sucked by the black hole towards my system inventory.

The body of Damien Miles was dried as dried mango and a dried salted fish.

I also shouldn't waste the brain of an archdemon.

I conjured a small sharp knife using my mana and used it to slice open the head of Damien and carefully scooped out his brain.

After I had removed his brain from his skull, I stored the brain of Damien inside the system inventory.

"I should be able to have a higher chance in getting some intelligence stats if I consumed an archdemon's brain."

"Now what's left was to check how my teammates were doing. If they got defeated by the archdemons, then as long as they weren't dead, I should be able to heal them. As for the archdemons, I'll do the same to them as what I did to Damien."

"After all, an archdemon's heart and brain is a rare delicacy because it was hard to get due to an archdemon having too much power compared to mere low-ranked demons and humans."

I cast [Flight] and went towards where my teammates had fought the archdemons before.

I witnessed the fight of my teammates against only 1 archdemon.

It seemed that the other 2 had already been defeated so we had killed 4 archdemons.

I should loot the corpses of the archdemons so that I would be able to taste lots of rare delicacies.

If those thousand-year-old mages and swordsman had known that I was able to increase my power just by devouring flesh, they would surely kill me for making their thousand-year training a joke.

The only archdemon who had lived was the archdemon of fire. Damn it! He's a tough nut!

It seemed that his fire magic wasn't just a party trick.

It even burnt all of Aerin's plants and trees which rendered her almost useless in the battle but she still had helped my other teammates in recovering their health points.

"Let me lend them a helping hand."

I created several water bullet daggers and shot them towards the archdemon of fire.

The firing speed was thrice as fast as a normal shot from a sniper rifle.

I used my magic to improve my eyesight and it acted as my gun scope.

I did a gun hand sign and directed it towards the archdemon of fire.

I created one huge water bullet and built up momentum on my water bullet.

"Bang!"

I released the huge water bullet towards the neck of the archdemon of fire and its speed was as fast as a rail gun.

As if reacting by instinct, the archdemon of fire then created a shield made out of the fire around him which blocked the huge water bullet.

I kept on firing towards the same spot I had fired the water bullet and so the embedded water bullet on the archdemon's shield was pushed until it passed through his shield.

It managed to hit his neck but only left a small wound on it.

"This is harder than I expected. Guys! Buy me some time!"

My teammates nodded and so I started to formulate my plan.

I wasn't an expert when it comes to using water magic but I was still someone who had an affinity towards all magic.

It should be possible to improve my proficiency in water magic but I lack the visualization that enabled a mage to improve his magic skills.

"I don't know if this works but it's worth the try."

I visualized a huge tornado and instead of it containing wind, it was replaced by an abundant amount of water.

"Whirlpool!"

A huge water tornado assaulted the archdemon of fire but his fire shield was still intact.

Although, it was showing some smoke so it was starting to dissipate bit by bit.

I visualized huge carnivore fishes that were made out of wood and had sharp teeth.

"Sharknado!"

I added wooden sharks on the whirlpool which increased the damage of the whirlpool and the sharks' sharp teeth were supported by the rotating force of the whirlpool which caused its power to increase by two folds.

The fire shield that the archdemon of fire had created was extinguished by the sharknado, a combination of water and nature magic that I had created.

Small wounded started to appear on the archdemon of fire's body as it came into contact with the sharknado.

Bits of flesh were being scraped off from the tough body of the archdemon as if the archdemon was being ground inside a blender.

It was all due to the sharp teeth of the wooden sharks that were being rapidly rotated which mimicked the rotating blade of a blender.

Blood started to spew out from the archdemon's body and it spread around the Holy Church like a fountain of blood.

The archdemon of fire had died due to blood loss and before the whirlpool was able to damage the organs of the archdemon, I canceled the sharknado and teleported towards the archdemon.

I materialized sharp long nails on my hand using my mana and used it to dig out the heart and brain of the archdemon.

I pulled out its stomach, liver, intestines, and other organs which seemed to be useful, well except for his appendix.

I stored all of the important organs of the archdemons inside my system inventory excluding the blood of the archdemon of fire which was diluted by the water.

I switched my gaze towards my teammates and found out that they were almost out of mana and had run out of stamina.

I used my [Restoration] skill on them to restore their stamina.

"It's just an archdemon! What's the big deal about it? Now get up and let's bring the recently summoned hero towards the Monster's Abode. We are going for an RPG leveling up training!"
