In front of the dilapidated and abandoned factory, the Deep Hound "Agou" "gazed" at the collapsed factory building with his empty eyes, as if trying to observe this ruin in the real world from another dimension.

Shirley stood beside Agou, looking around nervously. After checking Duncan's expression, she whispered, "Agou, is there really no 'residual pollution' here?"

"If you mean what ordinary people call 'chemical leakage', then don't worry, the pollution here has probably been cleared up a few years ago..." Agou's throat came with a hoarse and low voice, "But if it is 'pollution' in some extraordinary field, it's hard to say for sure."

"Did you find anything?" Duncan asked from the side.

"...No, really not." Ah Gou lowered his head slightly, "I just saw a flash of... 'fire', but now there is nothing. It may just be some kind of 'reverberation', a solidified memory left by this ruin... Many supernatural powers will leave similar traces in the real world, but to find out what kind of supernatural power it is... I'm afraid we have to go in and take a look."

"Then go in," Duncan nodded, and walked towards a gap in the abandoned factory, "You guys follow."

Shirley hesitated for a moment, but still followed. Agou shook his head left and right, and the black chain made a clattering sound. The Deep Hound looked at Duncan in front of him curiously and carefully: "Why... are you also interested in what happened eleven years ago? Of course, I just asked casually, a little curiosity. A big man like you must have your own..."

"Just think of it as my hobby," Duncan interrupted the Deep Hound. "Don't be so nervous in front of me. It makes me feel uncomfortable."

"Okay, okay, we're not nervous, we're not nervous..."

Hearing the other party's obviously nervous answer, Duncan just shook his head helplessly, and then looked at Shirley beside him with some curiosity: "You remember a big fire, but except you, no one else remembers the existence of this fire, is that right?"

"...Well," Shirley nodded. She had realized something by now. "Judging from your attitude...you also know about the fire, right? The fire really existed, right?"

"...Yes, I know, so now I am more curious about who erased all traces of the fire." Duncan nodded slightly and said lightly.

At the same time, his mind was filled with thoughts - he had never thought that things would develop so coincidentally, nor had he expected that there would be a third person in the city-state of Plande besides himself and Nina who knew about the "fire", his chance encounter with Shirley, their joint investigation, the fire that erased all traces, Agou's hallucination just now... These things seemed to be drawn together by an invisible force, like planets surrounding the sun.

This feeling that everything is being pulled together by an invisible force has made him alert.

Nina's textbook briefly described some "common sense" in the supernatural field, and mentioned that powerful anomalies or visions often have the power to interfere with the development of reality, and can even guide certain events to happen like weaving a script. Too many coincidences or continuous clues are often "omens" worthy of vigilance, which often means that the people involved have been affected by a certain anomaly or vision, and are unconsciously participating in or even promoting the event.

However, faced with this invisible and harmless push and influence, his "spiritual fire" was of no use.

Thinking of this, he couldn't help but secretly glance at Shirley.

The girl and "Agou" were cautiously on guard against any movement in the factory ruins. She seemed to have no unnecessary or complicated thoughts at all. Or maybe it was because this "big terror" of hers was so close that she had no extra thoughts to think about?

"...This looks like an ordinary ruin..." Agou's voice came in a low voice, interrupting Duncan's thoughts, "I don't sense any breath of extraordinary power."

Shirley raised her head and looked at the criss-crossing pipes and the twisted and deformed ceiling beams above.

This is the first "factory building" after entering the factory. It was severely damaged in an accident eleven years ago. Some powerful explosion pierced its roof, causing high-altitude pipes to break and building materials to collapse. The sunlight poured into the ruins through the large hole above, making the scene inside look like the jagged skeleton of a giant beast after its death.

However, apart from these explosions and collapses, there was no sign of "fire" in the factory.

"It doesn't look like there was a fire..." Shirley muttered thoughtfully.

"There are no traces of fire. This is the biggest problem," Duncan's deep voice suddenly came from the side. He also looked up at the broken pipes and roof structure, and frowned slightly. "This level of damage accident, and there was obviously an explosion, must have been accompanied by a fire. Regardless of the scale, there should at least be some traces of burning in the factory... But there is not even a trace of a flame here."

As soon as Duncan finished speaking, Agou spoke in a deep voice: "Yes, the current appearance of this place is as if... all elements related to 'fire' have been deliberately erased. However, because the erasure was too clean, it left a more eye-catching blank space."

"Erassed?" Duncan muttered softly, and slowly walked deeper into the factory. When he passed a group of abandoned and twisted machines, he stopped and casually glanced at a hole in the wall not far away.

He stopped suddenly, his eyes widening slightly.

Fire! A raging fire!

He saw a blazing sea of ​​fire rising from the opposite side of the hole, and the entire wasteland outside the factory was rolling in flames. The flames were like a surging ocean, rising into the sky and then rushing to the earth, rushing towards the nearby streets and houses. Thick smoke billowed up, and countless frantic crowds were running in the sea of ​​fire, like a mirage from hell!

This horrifying and blazing scene suddenly entered Duncan's field of vision, but the next second, when he turned around to call Shirley over, the scene of the burning sea of ​​fire suddenly disappeared.

Duncan blinked hard, walked to the hole and looked out, all he saw was a wasteland and a few dilapidated houses on the edge of the wasteland that were no longer inhabited.

Agou noticed Duncan's unusual behavior and immediately asked, "What did you find?"

"I saw it just now, too, fire," Duncan replied solemnly, "but it disappeared in the blink of an eye."

"It seems that the 'reverberation' left here is very strong," Agou analyzed immediately. "It reappeared twice in a short period of time. It is not a trace left by ordinary supernatural power. It seems that the 'sun fragments' that the cultists are looking for have indeed appeared in this place... I just don't know what the law is that triggers the 'reverberation'..."

Duncan didn't say anything. He just slowly returned to the place where he first saw the "reverberation" and looked thoughtfully at the place where he had just stood.

There seems to be nothing here.

After thinking for a moment, Duncan suddenly raised his hand and gently rubbed his fingertips.

A cluster of small green flames quietly and silently jumped out from his hands.

The moment he saw the green flame, Agou suddenly shrank his neck, and then took three or four steps back. With the sound of the black chain swaying, Shirley also took half a step back, looking at Duncan with horror: "You...you really plan to eat it?!"

"What are you afraid of?" Duncan looked at the duo expressionlessly. "This is not for roasting you."

As soon as he finished speaking, he pointed his finger at the ground.

The small green flame seemed to be a stream of water, falling silently to the ground. The next second, the translucent spiritual fire rippled and spread on the surface, and instantly swept over the area several meters under Duncan's feet!

Shirley looked at this scene in confusion, and suddenly her eyes widened: "...Ah?!"

Wherever the flames passed, something suddenly emerged from the empty ground.

It was a piece of ashes, a curled up piece of ashes in which one could vaguely make out a human shape!

It was a human being who was burned to ashes, and before he died, he was looking in the direction that Duncan had just looked at.

Suddenly, Shirley thought of something. She raised her head and looked around the empty factory.

Under Duncan's conscious control, the dark green spiritual fire swept across the entire factory like a breeze.

Thus, the traces that had been erased finally reappeared briefly in the eyes of the visitor.
