The narrow hallway that had just been bombed by grenades was much hotter than the Crystal Hall, and the charred corpses of Mongolian sandworms curled up on the ground, emitting the rich smell of barbecue.

However, Zhang Luo believes that after seeing the appearance of this thing, no one will be interested in its flesh.

The passage they were in at the moment was as narrow as the one they had passed through to enter the pyramid, and it was also free of forks and curves, still a standard straight line.

"What the hell is this?" The half-demon behind Zhang Luo muttered.

In fact, Zhang Luo has thought about this question for a long time, but he can't find an answer at all.

The pyramid, suspended upside down in an underground cavern, was even more bizarre than he had imagined. There is no doubt that this place is the weirdest place he has ever visited since joining the Strange Tales Research Society.

Although the content of this investigation mission is to "investigate the mysterious structure underground", judging from the current "investigation process", they are almost led by the nose by the contents of the notes, and if they don't find a way to solve it as soon as possible......

"Here we are." Frankenstein's cold voice came from ahead.

Seeing that the passage had finally reached its end, the four of them quickened their pace at the same time and entered the second "large clearing" in the pyramid.

Unlike the magnificent crystal hall surrounded by the obsidian throne just now, although the area of the open space this time is also very large, the style is much lower, because this place is simply -

"Hive...... Haziner's body shuddered.

What catches your eye is the white insect cocoons that cover the ceiling, and the green walls and floors, which look similar to the green slime secreted by Mongolian sandworms.

Obviously, the army of sandworms rushing towards the crystal hall just now should be living here!

"It's a disgusting place." The half-demon cursed something in Spanish.

But even in this environment, the exuberant curiosity of a fan of weird stories has not subsided:

"Those sandworms seem to have been raised here, and they live off what they eat...... Well, the problem is solved. ”

Standing in the corner of the wall and staring at the torn gray dress on the ground, and the human clothes that were also tattered and stained with blood, Zhang Luo instantly learned the answer to the question "What do insects eat for a living".

"It's disgusting, have they been eating people?" Seeing the clothes under Zhang Luo's feet, Hasiner, who was already very afraid of insects, couldn't help but take two steps back.

"So the question is, where did these people come from?" Zhang Luo smiled.

-- Just looking at the discarded clothes on the ground and the size of the sandworms, there were hundreds of people who were eaten here, if not in the hundreds.

"It seems that there have been disappearances in the Sahara Desert in recent years, but there are not many, and the four-person expedition that disappeared three months ago is the largest disappearance." Hazel whispered.

"So, where did these poor fellows get caught from?" The half-demon finally sensed the strangeness of the matter.

-- It is strange that hundreds of people have become food for the "worms of death" in this wormhole, and that such a large-scale disappearance has not been reported at all.

At this time, Frankenstein's words caught Zhang Luo's attention:

"It's kind of familiar." The girl in black lowered her head and looked at the long gray dress at Zhang Luo's feet.

Although it was torn to pieces, the leaf-shaped pattern on the skirt was still clearly visible, and noticing the familiar pattern, Zhang Luo immediately remembered something:

"It seems that when we first met, there was a beautiful woman wearing the same dress, right?" He looked at Frankenstein beside him.

――In the case of the train that opened the "new world" by herself, several passengers behind her helped push the "disabled girl" onto the train because Frankenstein, who had death attached to her at the time, had to board the train in a special wheelchair that suppressed the gods.

And one of the wheelchairs in the back is a young girl wearing the same dress!

Although it was likely to be a coincidence, Zhang Luo did not miss this detail, and immediately began to search for the same clothes of the train attendant among the clothing fragments on the ground, and then finally found a decisive clue.

"Whoa."

It took a lot of effort to take out the rectangular badge from the viscous mucus, Zhang Luo wiped off the mucus on it, and looked at the text on the badge:

"Express train K033, conductor, Zhao ......"

Although the name behind it and the photo below have been corroded to the point of being illegible, Zhang Luo knows that there is no need to confirm those contents, because-

He couldn't be mistaken, a month ago, the train that was used as Dracula's summoning altar and all the human passengers except himself died was none other than K033!

"In other words, are all these people the bodies of the passengers of that train accident?"

Even Zhang Luo, who has always been open-minded, was a little difficult to accept the truth for a while. After all, even he couldn't imagine this possibility!

――How did the bodies of the passengers end up in this hellish place when there was an "accident" on a train thousands of miles away?

At that time, the truth of the train accident should have been covered up by the official organization, and except for a few insiders, the outside world believed that it was a tragedy caused by the train derailment.

But even so, the relatives of the victims should have already brought back the bodies of their relatives and buried them.

Why do the bodies of these dead people appear in such places and become fodder for Mongolian sandworms?

"The car that was thrown out." Frankenstein said calmly.

"What do you mean?" Zhang Luo asked immediately.

Since he joined the Strange Tales Research Society to start his first mission after the train incident, he didn't pay much attention to the follow-up reports of the "train accident". I don't remember anything like being thrown out of the carriage either.

"In the train accident, the official said that two carriages were thrown out, and the bodies inside were unrecognizable, and they were collectively cremated." Frankenstein rarely uttered a long sentence.

Hearing this, Zhang Luo immediately understood what she meant.

"Could it be that the 'official' lied and transported the body here?"

――Because the members of the "Killing Troops of Heretic Creatures" he met before were so stupid, Zhang Luo did not connect those crazy psychopaths with this incident.

But in addition to the heretician killing force, there seems to be another organization that is also responsible for dealing with this kind of incident behind the scenes:

"Have you ever heard of the 'Monster Authority'?" Zhang Luo asked Frankenstein a question.

He still remembered a sentence from the "3.1 Investigation Report on the Serial Murder of Heretical Creature Murders" that he had read before: "At present, the case has been transferred to the heretical creature killing force and the monster management bureau for joint investigation." ”

It shouldn't be possible to do this with the heretic killing force, but if it's the mysterious "Monster Authority......

"Wait, you mean the Monster Authority?" Hearing this name, the half-demon next to him, who was still confused, immediately became excited.

Realizing what the half-demon should know, Zhang Luo looked back at the flat-headed man.

Then, he had a headache.
