Crossover Anime: Infinite God Creation, Yukinoka's Familia

Nangong Nayue drew three flame patterns on the whiteboard.

"In the first lesson, we will learn the basic knowledge of spiritual vision and the three fires of essence, energy, and spirit."

Shiyu took out her notebook and began to carefully record the key points.

Eriri also took out her notebook, but instead drew a chibi-style cartoon version of Nagisa Minami on it.

Mira listened intently, nodding slightly from time to time.

The next day, Nangong Nayue checked everyone's homework one by one.

Shi Yu submitted an 800-word observation report, detailing the three-fire states of the five people.

Mira submitted three sketches, depicting the three flame forms of different people, with every detail clearly marked.

Eriri handed over a drawing—a chibi version of Nangong Nayue with three small flames drawn on her head.

Nangong Nayue looked at Eriri expressionlessly.

Where is your homework?

"This is my homework," Eriri said matter-of-factly. "I used my spiritual vision to observe you and then drew what I saw."

"What I'm asking you to observe are ordinary people."

"Teacher, aren't you just an ordinary person?"

Nangong Nayue took a deep breath, suppressing the helplessness in her heart.

"Make a new one."

"Why should I?!"

"Because I'm the instructor."

Eriri pouted, reluctantly took out her notebook, and started writing again.

Luo Tian watched from the side and couldn't help but chuckle to himself.

Nangong Nayue walked to his side and glanced at his homework report.

The entire three-page document records the three fire states of seven people and details the impact of time, place, and environment on these three fire states.

"That's very well done." Nangong Nayue nodded slightly. "You're the only one among everyone who completed the assignment diligently."

"Thank you for the compliment, teacher."

"However—" Nangong Nayue changed the subject, "your observation has a fatal flaw."

"What's the problem?"

"You have never observed your own three fires."

Luo Tian looked surprised: "Observing yourself?"

Nangong Nayue said seriously, "The most important thing for a person with ability is not to observe others, but to see themselves clearly."

You must constantly monitor the state of your three fires in order to detect problems before the power gets out of control.

"How do you observe your own three fires?"

"Close your eyes and focus on feeling your shoulders and the top of your head."

Nangong Nayue gently guided, "You will feel three flames burning. The red flame is the weakest, the blue flame is the strongest, and the yellow flame is in between."

Luo Tian closed his eyes as instructed.

He could clearly sense it: a faint red flame on his left shoulder, a steady yellow flame on his right shoulder, and a blazing blue flame above his head.

"I felt it."

"Then remember this feeling," Nangong Nayue instructed. "Observe it once every morning and evening, and record all the changes."

"OK."

Nangong Nayue turned around and walked back to the podium.

"Today's lesson will teach you how to use the Three Fires method to judge the strength of your opponent."

She drew a simple table on the whiteboard.

"The opponent is a physically enhanced type, strong in close combat, but afraid of ranged attacks."

Yellow flames are vigorous, have strong vitality, possess self-healing ability, and are afraid of continuous damage.

Those with blazing blue flames are mental-type ability users, strong in ranged attacks, but vulnerable to close-quarters combat.

"If you encounter an opponent whose three fires are all extremely strong, don't engage them," Nangong Nayue said decisively. "Run immediately."

"What if we can't escape?" Eriri couldn't help but ask.

"If you can't escape, you can only leave it to fate." Nangong Nayue remained expressionless. "So it's best not to provoke this kind of opponent in the first place."

The classroom fell silent again, and Luo Tian kept those words firmly in mind.

On the third day of the lesson, Nangong Nayue explained the classification of Abyss items by level.

"Abyss items are divided into four levels according to their degree of danger."

She wrote a detailed explanation on the whiteboard:

Level 1: Safe to use.

It's easy for ordinary people to use, and there are virtually no side effects.

Level 2: Requires supervision by multiple people to use.

It can cause widespread destruction, with very noticeable side effects.

Level 3: Use is prohibited in principle.

It must be kept in strict condition; special authorization is required for its use.

Level 4: Absolutely prohibited from use and exploration.

Only the five permanent members of the Security Council know the specific identification number; there is no publicly available information about it.

"What level does the Demon Heart belong to?" Shiyu asked.

"It's a level 2 item," Nangong Nayue replied. "It can hypnotize women below the elite level and produces one drop of succubus blood every year."

The side effects are that women cannot use it voluntarily, the hypnotic effect disappears after the user's death, and repeated use will transform the target into a succubus.

"It sounds dangerous," Eriri whispered.

"So it must be sealed away." Nangong Nayue looked at Luo Tian. "Have you sealed it away yet?"

"It's already sealed," Luo Tian replied, "using the talisman provided by SDS."

Nangong nodded that month.

"The level of Abyss items is not static," she continued. "The danger level of the same item will change depending on who has it."

"What does that mean?"

"Some items are level 1 for ordinary people, but can become level 3 when used by a power user," Nangong Nayue explained. "Because power users can fully unleash the power of the items."

"What level is the Demon Heart in Luo Tian's hands?" Mira asked curiously.

Nangong Nayue looked at Luo Tian and slowly said, "Still level 2."

However, if it falls into the hands of a female ability user, it will become level 1—because women cannot actively use it.

"Can the succubus be used?" Shiyu asked.

"Succubi can use it," Nangong Nayue said, "but succubi are a demon race, and using the Demon Heart can easily lead to them losing control."

"It seems best to keep the Demon Heart sealed away," Mira concluded.

"That's right." Nangong Nayue nodded. "That's also why the SDS organization wants to reclaim it."

Luo Tian remained silent, knowing full well the true purpose of SDS's retrieval of the Demon Heart—not out of concern that it might harm people, but to study the artifact.

Zeus Industries wants to extract technology from the Abyss artifacts to create powerful weapons; that's the real reason behind it all.

On Thursday afternoon, Luo Tian followed Nangong Nayue to the LycoReco coffee shop.

Ju Wuxiang was already waiting in the private room, with a thick stack of documents in front of her.

"Have a seat," she said, gesturing to the chair opposite her.

Luo Tian sat down, while Nangong Nayue stood by the window without taking a seat.

"The results of the Devil's Heart's identification are in," said Kaori Tachibana. "Experts from Zeus Industries have confirmed that this item is genuine."

Luo Tian's heart skipped a beat.

"What are the next steps?"

"From now on, we've decided to let you continue to keep it safe," said Kaori Tachibana. "The Demon Heart is safer in your hands than in their lab."

"Why are you entrusting it to me for safekeeping?"

"Because its seal requires the talisman to be replaced periodically," Kaori Tachibana explained. "And you are currently the only person who has come into contact with it without being affected."

Luo Tian frowned: "What do you mean by that?"
