"Long ago, as one of the subjects at the research institute, I came here."

"But being a subject wasn't really terrifying at all. Everyone treated me well, and the most suffering I experienced during the experiments was just blood tests."

"During that time, I got to know many foreign technologies and scientists."

"Foreign things are truly amazing. Even to this day, I still haven't recovered from the shock brought by those complex and marvelous mechanical landscapes."

"The black pistol, the silver adorned electronic tube, the clay-yellow automatic door, the colorful potted plants—those were all things that amazed me and that I sincerely longed for. Even though all I had back then were plain white bed sheets..."

"They observed angels, studied angels, and controlled angels."

"Although it seemed like they had some grander experimental purposes, at that time, I was too busy falling in love to pay much attention..."

"I didn't remember to ask them for specifics."

The woman scratched her cheek sheepishly.

"Controlling angels requires very complex means."

"Although many spells can somewhat control angels, it's still far from maximizing their power."

"We tried many methods during this period, but the majority of them failed."

"Lost both the wife and the soldiers. Those failed angels in the laboratory weren't only uncontrollable, but also became very aggressive and destructive."

"As if their true nature was like that, just that something had previously suppressed them."

The woman walked and talked with Turing, navigating through the jungles of the mechanical building.

"We call those failed angels demons. Demons are a type of extremely difficult to eradicate byproduct of failed experiments."

"They have strong recovery abilities, and it takes immensely powerful magic to completely eliminate them for them to disappear."

"Otherwise, no matter what damage they suffer, they will slowly regenerate and return."

"If the subjects are smaller angels, we have the capability to eliminate them."

"But if the experiment produces powerful angels, we have no choice but to seal them or cut off their limbs and lock them away."

"Dangerous angels have their wings broken, sealed in the heavens, buried deep underground, deposited into the depths of the sea. Since we cannot kill them, this is all we can do."

"Demons are basically like nuclear waste. As garbage, you have to expend large amounts of resources and space on them, or else they can cause tremendous harm."

The woman looked back at the bewildered Turing, smiled tenderly, and said, "Sorry, you don't know what nuclear waste is, do you? Just forget I said that."

"Let's get back on track."

"Sealing is often not a permanent solution."

"The stronger the angel, the stronger the seal and magic it requires. The stronger the seal and magic, the more powerful the magician needed to maintain it."

"A reliable seal requires a genius mage's lifelong protection and maintenance. That's why we often say that while a seal deprives a demon of its freedom, it also deprives a magician of their freedom."

"The study of angels and demons has sacrificed the futures of many great individuals and the vitality of their youth."

The woman led Turing to a building that was shorter than the surrounding structures and knocked on the iron gate.

"This was supposed to be an automatic door, but it seems like it's no longer powered..." the woman looked at Turing behind her and said, "Can you help me open it, little sister?"

Turing glanced strangely at the woman, but didn't ask why she kept calling her little sister repeatedly.

A warm flame surged up from Turing's feet. With a swift side kick, the standard maneuver, the gate was kicked five to six meters away and disintegrated into pieces mid-air.

The scorching heat made Turing's already dry throat sore. According to the woman, she hadn't had water for nearly a day.

"So, was that angel from earlier also a demon? Since it was sealed too," Turing asked.

"I don't know, I know as much about the current situation as you do," the woman replied.

"But I think it's very possible."

The woman continued to lead Turing to the second floor. The hallway, now covered in rubble and remnants of moss, was originally a beautiful white stone corridor.

"This was where I used to live. I think we might find some food and water here..." the woman said, bringing Turing to the entrance of a room.

"I told you to bring me to the data room in the laboratory, didn't I? We need to find clues about the demon as soon as possible, kill it, and then we can leave this place!" Turing's tone was urgent; she didn't want to stay here any longer.

"Don't say it like that..." the woman's throat started to twitch unnaturally. From her dry lips, it was obvious that she hadn't had water for a long time either.

"You need energy to work properly... and...uh" The woman's body shook, almost falling down.

Turing quickly supported the woman and realized that her body was scorching hot.

[She has a fever? Of all times...]

"Alright, I'll listen to you and go check if there's anything to eat." Turing realized that she didn't want this woman to die so easily.

Turing supported the woman with one hand and used the other to push open the door with her recently healed hand.

Suddenly, a powerful roar echoed through the hallway, accompanied by a slight tremor of the building.

"What... what is that sound?" Turing froze as she pushed the door halfway. The overwhelming and resounding sensation, along with the iron-blooded courage struggling against the mighty force of the calamity, exploded like a stunning rose in Turing's heart.

"It's probably the demon... I suppose," the woman said. "There are some angels locked up in the containment room. If the power in the facility is also cut off, they will eventually escape."

"I see..." Turing grinned, her sweet smile hiding countless cruel intentions.

"It saves me the trouble of finding you all." Turing knew that she had to find a way to unleash her pent-up anger.
