The Goblin's Leveling System!

"We killed them!"

The supreme demons yelled in unison while letting out their killing intent.

I blocked their killing intent using my killing intent and I tried to intimidate and suppress the supreme demons using my killing intent but it hardly had any effect.

The supreme demons were too use to killing intent so of course, they had immunity towards it than normal demons.

Just like how a soldier who overcame several wars was much more fearless than a newly recruited soldier.

I cast [Wind Blade] towards the supreme demons but the supreme demons blocked it with their body

A demon's body was one of the strongest physiques compared to other races.

I felt envious of their body's durability but at least I had 100 million stats in defense.

"Get ready to fight! Use 20% of your strength to test the enemy! Only use 100% if you can't handle the enemy!"

I commanded Zale, Aerin, Sophie, and Mathew and charged into the supreme demons.

My teammates followed suit and took care of the other supreme demons.

I cast [Space Manipulation] and use its sub-skill which was [Teleport]. I teleported the supreme demons and my teammates outside so that we won't do any damage to the church.

"Interesting! I didn't know that this brat can use space magic! We must kill him first to remove a thorn on the demon lord's side."

One of the supreme demons spoke and he used his fire magic to conjure a demon flame but he didn't expect that I swallowed it whole.

"Are you sure this is demon flame? This is colder than my sun fire."

I mocked the supreme demons and cast [Artificial Sun]. A huge blazing ball of condensed fire was summoned in the sky and I launched it towards the supreme demons.

Sophie cast [Shadow Bind] while Aerin used [Nature's Cage] to trap and hold the supreme demons so that they won't escape.

After [Artificial Sun] came in contact with the supreme demons, it exploded and made a huge impact when it came in contact.

A massive fire explosion occurred which incinerated the supreme demon's skin and slowly burning them into death.

Unfortunately, the supreme demons' demon bodies were durable enough to only have their skin burned while their muscles remained.

But was [Artificial Sun] my only sun fire move? I still have two of them but they were still having trouble against my weakest skill.

Their death was already present.

I cast multiple [Artificial Sun] and fused it which led to [Ruthless Sun] being cast.

A gigantic blazing ball of condensed blue fire was formed in the sky.

I launched it towards the supreme demons and the supreme demons took out their defense artifacts and equipment.

Mathew used [Universal Steal] and stole the defense artifacts and equipment of the supreme demons.

Fear was present in the supreme demons' eye as they witness their doom.

I cast [Berserk] then my mind went wild as I started to lose control over my body.

My pale green skin turned dark red as my body was being enshrouded with a dark red aura.

My body moved towards the supreme demons. I bit them and eat their flesh while they were still alive so that I can digest their stats.

I covered my hand with mana and formed it into a claw. I used my mana-infused hand to dig out the heart of one of the supreme demons.

I felt a warm and sticky sensation as my hand went through the supreme demon's body and I took out his demon heart.

I took out a dark violet-colored heart that was currently throbbing despite being pulled out of its body.

I bit the demon heart and slowly chew it while savoring the taste.

My stats went up by a huge margin and I obtained the demon affinity.

The demon heart tastes like turkey meat but it tastes bland since I ate it raw and I didn't any salt or soy sauce.

The supreme demon that I took out a demon heart from flopped and fell on the ground.

I devoured its corpse and my stats were slowly increasing as I kept on digesting the supreme demon's corpse.

After I finished eating it, I glared at the four remaining supreme demons with killing intent and the eyes of a predator.

********

Several minutes had passed and I had devoured all of the supreme demons that had attacked us.

I started to gain some control over my body as [Berseker] started to lose effect but I still can't fully control my body.

The dark red aura that enshrouded my body started to turn light red until dissipated.

I walked towards my teammates and I launched myself towards them while enveloping my hand with mana to form a claw.

I directed my hand towards them and started to perform consecutive slashes while they dodged my attacks.

I went towards Zale and got a hold of his hand so I slammed him into the ground rendering him unconscious.

I went to Mathew and punched him on his stomach which took the daylights out of him.

I charged myself towards Sophie and grabbed her hair and threw her towards the nearest tree which in turn made her lose consciousness.

Lastly, I walked towards Aerin and gripped her neck while choking and lifting her out of the ground.

"Axel?"

Aerin was struggling to utter a word but she mustered her strength to utter my name and I lost consciousness...

********

I was lying in a soft bed and I looked at the ceiling. I glanced at the side and I saw Zale, Mathew, and Sophie bedridden as they were currently recuperating their injuries.

Now I felt bad since I was the cause of their injuries instead of the supreme demons.

Damn those demons for forcing me to use [Berserk].

I couldn't use [Sun's Wrath] back then since the surroundings might get destroyed after unleashing such a powerful spell.

If I want to, I could become the Eight demon lord and I might as well build my castle if that happens.

Wait... why not become a demon lord instead of being a hero? I could still kill the 7 demon lords while being a demon lord myself.

*That is possible. The host wasn't reincarnated to become a hero. The purpose of the host's reincarnation is to defeat the demon lords.*

*Even if the host becomes the next demon lord who will dominate the world, as long as the previous 7 demon lords were defeated then the host can do whatever the host wants.*

Nah. It's to cliche to become a demon lord. I'll rather stay as being an anti-hero than a demon lord who only said: 'Tremble before the might of this almighty demon lord!'

*I have to remind the host that evolution is possible.*

Wait... what? I only remained as a goblin hero for a month so I didn't know that evolution will be possible.

*Remember how the host became a goblin hero by killing the human hero? It is possible to evolve into a species that the host will devour or kill.*

*If the host devour an entity from another race, then the host can evolve into that race with a higher chance than killing an entity from another race*

So in other words, I can evolve into anything as long as I devour or kill that entity from another race?

*The host is right.*

Should I devour a human or an elf to evolve into that race? I can evolve into a dragon using the dragon's heart that I obtained from the dragon king's cave.

I went outside the house that I was staying at and took a stroll. I wandered and went to a forest.

I took out the dragon king from my system inventory.

A huge dragon suddenly appeared in front of me and it stood proud while releasing a menacing aura.

"I thought you have forgotten about me? What's the change of heart to remove me from the space you sealed me into?"

The dragon king proudly spoke while flapping his wings to produce gusts of wind towards me.

"I need you to sign a pet contract with me."

I answered the dragon king while taking out a brown scroll from thin air.

"How dare a mere goblin make me its pet?"

"You have no say in this!"

I yell while suppressing the arrogant dragon king using my mana.

"You can't suppress me with this measly amount of mana!"

The dragon king retorted while releasing some of his mana to counter my suppression.

"I haven't even used a tenth of my mana yet! I was only using a hundredth of my mana and you are already having a hard time. What would happen if I use a hundred percent of my mana?"

The dragon king went silent and fear could be seen from his eyes.

The proud dragon king doesn't have any choice but to become my pet.

I used the contract scroll and then the dragon king became my contracted pet.

"Now what's left is to make the demon prince my slave!"
