Hypothesis

Within the vast expanse of space of the milky way galaxy is a spaceship colored black with tentacles in front while the back was built in the shape of a nautiloid's shell.

Within this spaceship are beings with heads the shape of an octopus, with tentacles besides their mouths and a hole at the side of their heads all covered in purplish skin as they plan their next attack on a planet not too far away.

In a separate chamber illuminated with green light atop this ship, two high-ranking aliens are telepathically conversing with a brain with tentacles on matters that shall later affect two entire races.

"My lord, 'that' will soon be ready," said Ag'im

"What about the rest of the preparations," asked the brain

"It is underway as we speak, my lord," said Ag'im

"We have only one chance at this, failing will derail our plans or might even render it useless," said the brain

"We shall not let that happen, my lord," said Ag'im

"Go, and make sure there are no mishaps," said the brain

"Yes, my lord" Ag'im said as he and Sa'un moved with haste to ensure the plan is carried out smoothly.

--------------

It has been five days since the alien's abrupt retreat, along with the disappearance of gates around the world, world leaders are still not allowing commoners to roam about, hunters lower than A rank are being far more active than before as they rush to increase their strength in dungeons, and scientists making consecutive breakthroughs as they reverse engineer the plasma guns the aliens used.

Hunters above A rank are busy committing themselves to community service as move with haste rescuing unlucky civilians trapped under debris or killing any monster still alive.

People around the world are moving with haste as they continue to grow stronger to make sure their next war would end in their favor while some do it to protect those close to them, while somewhere else;

A dark blue creature could be seen standing on an island suspended in the middle of the ocean as he converses with an entity only he can see.

"So what have you found out about the aliens," asked zephyr

[It seems my hypothesis was not completely wrong]

[Their level of technology is still far above the humans, direct confrontation would have lead to the total annihilation of humans]

[Their mind capabilities far exceed anything humans, but their physical prowess is lacking]

"Oookay, what about my powers? what else did you find out?"

[Mostly things you already know]

"Such as?"

[Your body hungrily feeds on organic and some non-organic substances for purposes I'm not sure of yet]

[It also absorbs, no devours nova essence at an absurd rate, the amount used to teleport you each time is enough to teleport this entire island you're standing on]

"Any idea why?"

[Not yet, you just have to keep practicing for now]

[But I noticed something peculiar]

[Nova essence constantly destabilizes around you]

[it's as if it's afraid of you]

[That's why the monsters couldn't their skills against you]

"Now that you mention it". He began to reminisce on the battle's he had with monsters, indeed none of those who fought him close had used skills, which was part of why he been able to defeat monsters ranked above him, he hadn't paid attention to it while fighting, but now the planetary core said it was because of his powers, he couldn't help but be curious about what exactly he had become.

"And the aliens?"

[So far, there hasn't been any movement, which can only mean one thing]

[They pulled back, and are now planning to bring more firepower and reinforcements]

"Then we'll have to be ready for them"

[That is easier said than done]

"What do you mean?"

[To make better dungeons more essence is needed, the amount gained can only make two SS rank dungeons or six S rank dungeons]

[You might think that it's plentiful, but I have to constantly resupply energy to keep it from falling apart, which means we need something that will constantly supply us with essence]

"Where are we supposed to find something like that?"

[We can't, nothing of such exists in this galaxy]

"Then what should we do? there has to be a way"

[There is one way]

[We'll take it from other planets, the amount of essence created in this planet cannot meet its daily needs, so we'll take it from other planets]

"How?"

[By forcefully taking over another planet]

"How are you going to do that?"

[I'm not doing anything, you are]

"Wait, I might be strong but I'm nowhere strong enough to take over a planet"

"Heck!, I'm not even strong enough to defeat the aliens by myself, how am I supposed to conquer a planet? are trying to get me killed?

[It's not what you're thinking, you'll just have to-]

"Have to?"

[I'll explain later, the aliens are back and with more numbers than before]

"Let's go, we can't have a repeat of last time," he said as yellow particle coalesced around and then;

WAP!

-------------------

Tens of jet-sized spaceships were entering earth's atmosphere by the minute but they were greeted with bombardments of skills and weapons made of plasma from hunters.

Humans had developed a device capable of tracking the aliens so they had the hunters prepare for another war.

All around the world, explosions ran rampant as a second war was underway, with the hunters and soldiers with plasma weapons standing their ground far better than last time, but of course, it couldn't be that easy.

"Guy's is that...oh no!" gates began to emerge all around the world but they were only ten in number, which should be good news, but there was all S+ rank and above gates with monsters of the same rank coming out.

This raised alarms within hunter ranks as high-ranking hunters had to divert their attention to the incoming monsters as fast as possible, leaving low-ranking ones to deal with the spaceships.

Which began to result in more casualties of the hunters, but all was not lost because;

WAP!

Their dark blue guardian angel had appeared to help to close the gates as fast as possible, which reduced the casualties and allowed some high-ranking hunters to help in fighting the spaceships, but that's when something funny started happening.

As zephyr sealed a gate another emerged to take its place, like a game of 'Whack a mole', as the gates were consecutively maintaining the number ten, as one is closed one is opened, which also caused the planetary core to use up more nova essence as it teleported zephyr around the world.

"Something's not right," Zephyr said as he increases his speed of mowing down the monsters with his ever-changing body structure to defend, attack, slash and slice through the SS rank monsters, he could almost tell that something was not right.

'But what is it? this was the question that was bugging him as he didn't know what the aliens were planning to do by keeping him busy like this.

He had made the system send a message to hunters worldwide to stay on alert, thinking that they wanted to mow down the humans starting with the weak, and that was why they were keeping the real powerhouses busy with the emerging gates, but there didn't do that either.

'Then what could it be' zephyr was thinking of other possibilities as the planetary core told him of the situation hadn't gone as they expected, then he thought;

'Am I the target?' that was possible as he knew he would have come into their radar with his contribution in the last battle, but still.

'Did they think the SS rank monsters would be able to defeat it' he shook his head at that thought, the planetary core had said they had exceptional brains, underestimating an enemy would only lead to one's doom.

Just he was searching his brain, the answer came akin to a revelation.

DOOOOM!!!!!!
