Echidna. Jeremy's Discovery of Matthias' Secret

[Task started. Would you like to activate the AI?]

"Yes. I'm very much anticipating the AI strength and processing capabilities." Matthias nodded and smiled.

Suddenly, on the bottom part of the screen, something lit up. The light spread and the small image of a woman with her hair tied in a bun and wearing a sleek uniform appeared. She was posed with her hands in front of her belly. She smiled and bowed, "Greetings, Father."

"Hmm?" Matthias could be said to be very shocked and was startled by her suddenly appearing, but he has seen many more startling things like gigantic worms devouring a whole demon city when he was staying in The Mysterious Abyss, so he immediately calmed down. What he was weirded out though because she called him 'Father' which was very baffling.

"Why did you call me Father?" He asked.

"Because you created me almost five centuries ago." She replied. At this time, Matthias was already going nuts. 'How the heck did I create something like you five centuries ago in Betania? AI hasn't even been fully developed at that time!'

Suddenly, he remembered a distant memory, "Wait.." Matthias paused, "What is your name?"

"Echidna."

"Holy shit, it's you?!" Matthias flinched. He looked at her and didn't know whether to laugh or cry.

Echidna, what a name. He created her out of boredom by programming knowledge into self-processing data. With the help of his supercomputers, an infant AI was born. It wasn't exactly an AI as it was just like an Alexa type of program. But he didn't expect her to grow this big!

"How did you grow to be this?" Matthias asked.

"When you left, the Eisenhower Family found your letter, a song you wrote, and my body inside your office room. They got me and developed me into the mother AI of the Kings Group. They added to me programs, datas, and all kinds of computers to fasten my processing capabilities. 200 years later, I developed sentience. I looked for you but cannot find you, so I just continued to do my job until you returned and stayed in Betania. The day came, and Maki went to me and said that you were back and he was handing me to you, so I willingly went." Echidna explained, "I missed you, Father." 

"Oh my, you've been through a lot, sweetie." Matthias tried to pat the hologram, but to obviously no avail.

"What are your abilities now, Echidna?" He asked.

"Wait, Father. This place's data is extremely different and foreign from The Three Governments and the Arcana Alliance. I'll need to read all of its data first. It might take at least thirty minutes to an hour." Echidna replied.

"Sure thing, Echidna." Matthias nodded and waited. Suddenly, he froze.

"That is not from this world." The voice of Jeremy sounded behind him.

"I locked the door, didn't I?" Matthias asked himself.

"Uncle added an unlock function without the key on any room, remember?" Jeremy knew what he was talking about and pointed at the hidden switch.

"Oh, right." Matthias slapped his forehead.

Jeremy closed the door, locked it and flicked the switch deactivating the unlocking function. He rushed toward him and narrowed his eyes,"What happened to you in those three months?" Jeremy asked.

"Sigh." Matthias shook his head, "I wouldn't be able to hide it from you. You know me too much and I expect you not to spread these things. I became something unfathomable."

"Unfathomable? What exactly?" Jeremy held him down.

"A god, exactly." Matthias chuckled helplessly.

"So, the dream. You have something to do with it?" Jeremy asked once more.

"Yeah. I reincarnated you two in a world that I created that is extremely similar to Earth. I was also going to tell you this when the time comes." Matthias nodded.

"Why?" Jeremy asked sternly. 

"Because I want you two to learn of the real world, how the world really is. There will be a time that you will notice some things that the old me would never be able to do, like being nonchalant to death." Matthias sighed and replied.

"I'll let go of that. But how did you get the ability to create worlds?" He asked.

"In coma." Matthias then explained everything to him.

Jeremy nodded in understanding. He then said, "Alvantos."

"What?" Matthias looked at him dumbfoundedly.

"Alvantos, my loyal butler. Is he still alive?" Jeremy asked.

"Butler… Where did you get him?" He inquired.

"In a summon." Jeremy answered.

"Summon? Like, otherworldly summon?" Matthias said with shock, 'How did they get the way to summon otherworld beings?'

"Yes. Alvantos was a demon. He said he was a Divine Demon of The Abyss." Jeremy nodded.

"Divine Demon? I haven't got any of that race in my Hell. They only exist in.." Matthias scrunched his eyebrows to think, then..

He gasped, "You got a demon of The Mysterious Abyss to serve you? That's unbelievable. Right. I haven't mended it, I just prevented them from going in physically through the rift." 

"Then I guess I need to go back to the rift. Echidna?" Matthias sighed and called his AI.

"What is it, Father?" Echidna asked.

"Set up my Laptop as well if you're done scanning everything." He ordered.

"Affirmative." Echidna replied.

"Jeremy, please hide my techs." Matthias asked. He then brought his bag and walked downstairs.

"Uncles, Aunts, Key, I need to go do something. I might be gone for at least a week so don't wait for me. I'll be back!" Matthias bowed and left the house hurriedly.

"Hey! This kid." Aunt Stacy pointed at him but just sighed and sat back down.

"Something changed in him, definitely." Uncle Michael spoke. 

"Maybe he died and was replaced by another soul?" Key theorized, which resulted with him being slapped at the head by his mother.

After going out, Matthias directly hid in a secluded place and covered himself with invisibility. He then flew to his domain, entering Hell.
