I Only Wanted A Class In The Apocalypse

"Oh, I developed a technique, opening a gate towards my world, and then could send anything there. But if I sent anything weak, my world would devour it, turning it into a pure form of energy."

"That's… You simply tossed them there, without giving them any of your stamp or signature, right?"

"What… Are these?"

"Oh… That explains it then… But if the ones you sent are already living?"

"Those folks? Yes they are crazy monsters with colossal bodies and tons of energy," I waved my hand to reassure him. But he ended up getting shocked and he eventually signed.

"Lord… You are truly blessed with the gods of luck! You managed to find such fierce monsters, let them survive the cruel world of yours. That means they are really strong, formidable to be honest. And they will just form great generals for my lord, leading his forces out there."

"Well… I think they are dependable and quite capable," I didn't get much from what he said, except that the little ones I sealed and formed a tattoo over my back were formidable. And that was something I could vouch for.

"Lord, sending anything there without getting the stamp of lord, a mark of lord's energy, then the world will consider them as hostile beings, start attacking and devouring them. Only those exceptionally strong enough will sustain such brutality."

"I see… And that stamp thing… The mark of my energy, how can I leave it over others?"

"There is a technique… There are lots of techniques about this world that the lord has to learn before truly unleashing the power of his world."

"Teach me then," I was eager to fully utilise my shadow world to the fullest, "I want to send monsters there to evolve."

"Lord, you got to know that the capacity of this world is limited so…"

"Don't worry, I'll work first to expand this world, then I'll let many enter it," I got his point, "but can I send anyone there? I mean, can I send people as strong as you?"

"Lord, it's an honour to join and live inside your world," and against my expectations, as I just asked this question on a whim, he suddenly fell on his knees, cupped his hands, and added:

"If lord permits, I can go out now and select the most capable ones of our clan to join lord's world and crusade."

"Your clan? Will it only be enough to depend on the shadow clan?"

I got that these folks used the same power as mine, and that meant they'd gain much more harvest than any other clan.

But if I just depended entirely over them, that meant I'd gain lots of mediocre forces. He said it himself, the other forces around my world were all formidable.

"Lord… Letting others join won't be a good idea. They won't get the best out of this chance, believe me lord…"

I raised my hand to stop him. This dude… He was just thinking about the benefits gained for his people. "I promise that your clan will be all moved towards my world when I expand it enough. But I have to first expand it, you got my meaning, right?"

"Sure…" he said in such a dejected tone, "I'll go and see other clans then."

"Good. but first teach me stuff about how to let people in and out."

"Lord can give me an hour, I'll draw all the techniques I'm aware of about this legendary world. Then the lord can sit and study them here while I'll go all around to gather the strongest folks from each clan."

"Cool."

It was a fair offer. I got him paper and a brush, let him start working while I watched.

He kept drawing and writing, and I couldn't help but peek from time to time.

At some point, I stood next to him, watching whatever he was writing.

"So these are instructions about hand seals and techniques, right?" I got lots of papers and techniques, and I noticed that all of them depended on a stance, a series of movements of my hands and fingers, ending up with saying a few words and using my energy in certain ways.

"Yes, lord is right," he nodded, "our techniques all depend on these steps, a stance, hand seals, energy channelling, and words said. Isn't this how the lord did his techniques?"

"Well… I never shouted any words to be honest," I looked at one drawing after another.

"This… Then how?"

"I used to write words using my blood and energy," I shrugged, raising my head from the papers, "that way my techniques work."

"This… Is quite remarkable!" he was shocked again, making me sigh inwardly.

"Ok lord, I'll go and see others. But always remember, saying words is always more efficient and easier than writing them. Despite writing them means a much more complicated and fiercer form of the final technique."

"Ok," I got his point. It was easier to speak the words than write them down. But writing them down would turn any technique stronger.

Well… If I have time then it should be done by writing and not shouting the words, right?

As I watched him leave, I started to study what he left for me.

Well… He left tons of instructions and drawings, making me feel at loss at first.

But gradually and with the passing hours, I started to get a grasp on what was going on here.

He didn't lie, there was literally everything for anything I wanted to do there.

Wanting to send people over? Simple! A variety of techniques were there in front of me, allowing me to send different amounts of people inside.

There were techniques that would allow for tens, hundreds, and even thousands to enter, and there were others who would allow for hundreds of thousands and up to a hundred million inside.

The main conditions were to have enough space inside my world, and to spend different amounts of energy for each technique.

Of course the main problem for now was the limited size of the world. According to a drawing he left behind, I got that my current world, the startup one, would allow for only ten thousands to be there at most.
