After trolling Erskine for a little bit more, Eldrin finally decided to stop mentally torturing the poor man.
Erskine's face was red from anger, but he took a breath to calm down,his voice calm.
"You have a little too much time for a man who is supposedly fighting an endless army by himself"
Erskine sat down at his desk and asked.
"You need vials?The Viltrumite ones?"
Eldrin didn't even get the chance to say anything before he was handed a small box.
Eldrin looked at it curiously, his expression filled with bored intrigue.
He looked at Erskine.
"An artifact?"
But Erskine only smiled and said.
"Open it"
Eldrin did just that; he opened it and surprisingly, when he looked inside it,he could see a warehouse with 30 Viltrumite serums.
Eldrin nodded, slightly impressed.
"The Ancient one or some rookie mage in teyvat?"
Erskine smiled proudly.
"The latter,ridiculous I know"
Eldrin shook his head in disbelief; that was quite the surprise for them to grow to such a level that fast.
Erskine's eyes shone, his voice serious.
"Eldrin,we may have a solution to the war"
Eldrin's eyes glinted in interest.
Erskine recounted what the ancient one had said and explained it to Eldrin, who was astonished, something very rare.
Eldrin's eyes narrowed as he thought for a while.
"It could work"he finally said.
"Science alone cannot possibly beat such creatures of magical descent...especially Dormammu"
He nodded, now assured.
"We will fight magic with magic..Ensure that teyvats development accelerates,they will be vital allies"
Erskine's face screamed,"No shit Sherlock, already on it"
Eldrin noticed that, his expression deadpan.

Back to the Invincible world, a portal opened in a warehouse of the empire and Eldrin's clone emerged from it.
Sebastian had already teleported in front of the portal.
Eldrin tossed him a tiny box.
Sebastian's eyes widened as he dived to catch it. He got up while holding it.
"Are fucking crazy?!"
Eldrin looked at him, his voice firm.
"Language, young man"
A vein in Sebastian's forehead almost erupted from the anger, but Eldrin continued as if nothing had happened.
"In that box is the thing a man dreads but also lusts for.. p-
But Sebastian interrupted him.
"Nobody gives a damn..My liege"
He opened the box to see 30 vials of what they desperately needed, smiled, and teleported away.
Eldrin was left awkwardly standing there. He shook his head and signed.
"They grow so fast..his already like a teenager, rebellious, full of excitement and youth"
But he smiled.
At least he gets to keep his childhood...That's good.
"WE ARE THE SAME AGE MY LIEGE!"
Sebastian screamed telepathically, but was completely ignored by Eldrin, whose smile turned into a sadistic grin.
Eldrin's eyes lit up as he got an idea.
"Why not send him to school?Maybe this loner will finally find some friends"
"NO IN A MILLION YEARS MY LIEGE, YOU HEAR ME!?I AM NOT GOING TO FUCKING SCHOOL!"
Eldrin's sadistic smile became demonic.
His voice filled with sadism.
"He needs to learn a thing or two,get a girlfriend or whatever humans call it"
Eldrin's eyes glinted with sadism too.
"He needs to help his old brother with future paperwork after all"
Eldrin chuckled evilly when he didn't hear Sebastian speak telepathically.
"Did I break him?"
He thought in amusement.
But then he shrugged and teleported away.
Sebastian this night will have to sleep with one eye open...Oh wait his doesn't actually need to sleep.
Days passed, development continued at an impressive pace,the empire of the invincible world started to mass produce weapons after their SSS-enhanced scientists finally managed to reverse engineer them, allowing for mass production,spaceships, other vehicles created for both war and transportation,weapons of all kinds.
They started building their first Arc after they found the schematics.
Their goal?
To create a contingency plan in case the Earth falls,but currently they planned to train Astartes soldiers and send them to fight along with Eldrin to buy more time.
Although Eldrin did not like that at all,he understood the necessity of it; he alone can hold back this Endless army for only so long before he gets overwhelmed,at most by himself, he can buy them 3 years, maybe even more if he gets any stronger.
As unfortunate as this was,there wasn't much he could do; he was just a man after all,not a god.
Meanwhile, the human empire's population multiplied. LHS 1140 b can actually sustain more than 40 billion humans,But because it's mostly a water world with no big continent's it's limits is around 20 billion before they would be forced to create cities underwater like Talokanil.
So they were moved to LHS 1140 C, which was actually scorching hot in the beginning due to being closer to its star,yet after Erskine moved the whole planet with the help of the space stone and telekinesis far enough to mimic Earth's temperature,the planet entered a process of cooling down, making it habitable.
There was no actual dissatisfaction for those who were moved since they received massive compensation in return,an offer they could not refuse if they were sane.
And like that, the colonisation of another planet began,or actually,it ended, since the cities and necessary infrastructure had already been built by Erskine.
