Chapter 79. Dekan-style Reasoning Method

“You mean, when all six corners of the array are lit up with red light, the vampire might appear?”

“Take out the ‘might’. If two more of us die, we will have to face Viscount Augustine the vampire.”

Upon closer inspection of the base under the piano, it seemed to be a large coffin embedded in the ground.

It must be the hiding place of that "Viscount Augustine the vampire".

“Then how exactly did the mansion owner die?”

Lilith asked, still puzzled.

“No matter how you look at it, it's suicide.”

Generally speaking, a scene that looks like a suicide is unlikely to be a suicide.

But to be honest.

As a rather experienced professional in the field, I felt that this was a suicide.

In this kind of world, there was no need to make a murder so fancy.

“Then why did he commit suicide?”

“Perhaps he was being controlled by the vampire and wanted to sacrifice us, but in the end, he regained a trace of sanity and, in his struggle, stabbed himself.”

When I stated this conclusion, the long-stagnant mission prompt finally began to update.

【Viscount Augustine was severely injured after being crusaded by the church. On the verge of death, he sealed himself in a magic coffin.】

【He enslaved the remnant souls of the witch and the werewolf, and cast a curse on the mansion, which would continuously erode the mansion owner's mind and control their thoughts, making the owner offer sacrifices to him. By offering the souls of six Rank 3 or above powerhouses within three days, Viscount Augustine will be resurrected.】

【So many years later, one day the mansion owner invited a group of friends to the mansion as guests.】

【He planned to offer them as sacrifices to Viscount Augustine.】

【However, the mansion owner still retained a final sliver of clarity. He knew what consequences his actions would cause, so during a brief moment of regaining his self-awareness, he chose to commit suicide.】

【He also became the first sacrifice.】

【But two people have already been eroded by the mansion's curse, obtaining the power of the werewolf and the witch, and are about to release Viscount Augustine.】

【The core plot is now complete.】

【Information unlocked. The Rebellious Challengers' mission is: Summon the Rank 6 vampire, Viscount Augustine. After the mission time limit ends, Viscount Augustine will be teleported to a random coordinate in the challengers' original world.】

“You really deduced it correctly?”

Lilith's face was full of shock.

She had originally been struggling with how to solve the murder case of the mansion owner, but she didn't expect it to be so simple.

“It was all thanks to my young lady's hints.”

I retreated behind Cornelia and said with a smile.

Actually, my deduction this time was mainly based on a guess.

If the mission prompt hadn't updated after he finished his explanation, he was prepared to come up with another hypothesis.

Until he guessed correctly.

After all, the first 1/3 of the information was given directly by the Shadow World.

And only the middle 1/3 of the information could be obtained through collection and investigation.

Then the last 1/3 was most likely obtained through reasoning.

As long as the reasoning was correct, the Shadow World should update the prompt.

And he already knew the conclusion "killing six people will make the vampire appear".

Using the conclusion to fill in the process, at worst he would just have to try a few more times, and he would eventually get it right.

Cornelia still had that calm poker face, as if she was hiding her merits and fame.

This time, Lilith stared at Cornelia for a long time, then showed a relieved smile.

She was finally completely convinced by Cornelia's wisdom.

As expected, the Shadow World would not make a mistake in selecting the detective identity.

At first, Lilith had even felt that she was smarter than Cornelia, but now she only felt ashamed.

“Then may I ask, what should we do next?”

Lilith asked Cornelia respectfully for advice.

Cornelia remained silent.

She didn't know.

She only knew that she was going hunting later.

“My young lady means that we can proceed according to the original plan. Let's go investigate the deaths of the three kingdom knights first.”

I explained Cornelia's meaning in a serious manner.

The reason he was not in a hurry to expose the werewolf right now was—

This venue was too terrible.

If he failed to control the enemy and pushed them into a corner.

Then the enemy would take the initiative to sacrifice themselves. If the death toll reached 6, the vampire would appear in the living room on the spot.

Although I could use a mutual destruction plus lock-blood playstyle to inflict so much pain on the vampire that it would pass out.

But the vampire might not prioritize attacking me.

He couldn't protect the safety of others.

So he needed to lure the enemy to a better position first.

Everyone nodded frequently and headed towards the bedrooms together.

Everyone knew that if the regular challengers were to win, they could only win today during the day.

Otherwise, when night came, they would almost certainly lose today.

So this time, everyone revealed their room numbers.

Lilith and her guard were 201 and 202.

The twin sisters were 101 and 102.

The first to go to their bedrooms last night were me and Cornelia.

Next were the twin sisters.

Then Lilith and her guard, and finally the three kingdom knights. Their room numbers were undoubtedly the remaining 103 to 105.

First, Lilith's guard attacked the door of room 103, but failed to make any impact on it.

This meant that the blessing on the door had not been destroyed.

However, just as everyone was about to go to the next room, Cornelia frowned and sniffed.

She gradually lay down on the carpet, then went to the crack of the door of 103, sniffing more and more seriously.

“There's the smell of blood.”

Cornelia said with great certainty.

“Impossible, the room wasn't broken into, how did the people inside die!”

Lilith's face was full of doubt.

The culprit couldn't have entered through the window either, because the window was as indestructible as the wall and couldn't be broken into from the outside.

Next, they tested the doors of rooms 104 and 105, and the result was the same.

The blessing on the doors was intact, there was also the smell of blood coming from inside, and there were traces of blood stains being cleaned up on the carpet in the corridor.

The three kingdom knights should have died in these three rooms.

“The three of them were staying separately...”

Lilith bit her lip, her expression conflicted.

That wasn't hard to explain.

A Rank 4 knight, even if two of them stayed together, would probably not be able to resist a Rank 6 werewolf's attack.

So they should have chosen to stay separately to increase the number of distractions.

Even if they were truly unfortunate, they could still leave more information for their companions.

But the problem was, why were three people killed in different rooms in one night?

Wasn't the witch only able to break the blessings of two rooms?

The most bizarre thing was that the blessing on the doors was not broken at all.

Things had become confusing again.

A locked-room murder case that would decide the outcome was laid out here.

If the reasoning was successful, it would be a victory for the regular challengers.

If the reasoning failed, it was very likely they would be wiped out.

But I didn't need to reason.

If you want to know the truth, wouldn't it be much more efficient to just catch the murderer and interrogate them than to reason?
