Dialogue
Investigate- Let's see what you've found... A book? The variety of inmates in this Shackling Prison is truly intriguing. Since books are spiritual food for the soul, maybe there is a spiritual inmate who's an avid reader and relies on them for sustenance.
- Then again, you've always been quietly stashing away various books (and even non-books) from different worlds into your bag, never quite sure when you'll look at them again... Hmm, allow me to pose this question, but do you truly intend to read them?
I read every single one of them. They are interesting.
- Thank you for your support. Stay tuned for more upcoming books.
I'll read the ones with interesting titles.
- I see... So this is similar to browsing online communities.
I haven't read them for a long time. Words put me to sleep.
- I understand. After all, there are many ways of getting information these days.
- So, this book is... A Study into the Mara-Struck?
- You have a faint recollection of the book's title. It appears to have been listed as a recommended title in the Express data bank when you first embarked on the Xianzhou. Several people in the Cosmos have been desperately searching for its whereabouts to no avail.
- Take it along with you. Maybe Dan Heng, the caretaker of the data bank, will thank you for it.
Take it.
Not interested.
- It appears you're not particularly interested in examinations related to the mara-struck. After all, as someone who's not a Xianzhou native, it's not a concern for you... However, should you find yourself with spare time, feel free to take and read it at your leisure.
- Because there's a possibility that this book isn't lost in the prison but it's locked in the prison.
- (Attempt to move away after taking the book)
- New Prison Guard: Wait, did you take that book A Study into the Mara-Struck with you just now?
Yes, I love to read to widen my knowledge.
- New Prison Guard: It's got nothing to do with whether you like to read or not. You are helping it to escape from jail!
Didn't you place it there for me to take...?
- New Prison Guard: For you to take? No way. You are helping it to escape the prison!
- New Prison Guard: I've only recently been assigned to this section of The Shackling Prison, so I'm uncertain about this book's circumstances. However, judging from my experiences, it's likely here for a reason.
Are you serious? Are you sure this isn't a joke?
- New Prison Guard: I was hired as a Jailer in the Ten-Lords Commission because my personality is always serious. In my opinion, this book must have done something wrong and been arrested.
So that's the reason no one can find this book...
- New Prison Guard: ...Is anyone searching for this book? Please inform them that this book has been apprehended, which is why it's not readily available. My apologies for any inconvenience.
- New Prison Guard: In any circumstance, the Ten-Lords Commission will not make a mistake. We will never mistreat a good book.
But what exactly is the charge?
- New Prison Guard: ...Anyone without a charge will not be in prison. You're right. Let me do a quick check now.
I got it. I will leave this book behind.
- New Prison Guard: All right. Then I'll... On what charge should I rearrest it? Let me do a quick check.
- The inexperienced and unseasoned prison guard begins her search before you. What grievous offense could a mere book have committed to warrant imprisonment in The Shackling Prison, to the extent that numerous individuals across the Cosmos had gone to great lengths to search for it but had all failed?
- New Prison Guard: This is weird. There isn't any record in the system. Could it be that it's not a criminal?
That is more in line with my common sense...
- New Prison Guard: You are right. You may bring the book along with you.
So I can take it with me now?
- New Prison Guard: Yes, you may take the book with you...
- New Prison Guard: I've got duties to attend to and need to get back on patrol. If you are curious about why the A Study into the Mara-Struck book is locked up in prison, you can seek out Jailer Chiyi for further information.
- The new prison guard scratched her head and left. A Study into the Mara-Struck is now your book.
- You finally get your hands on the unfindable A Study into the Mara-Struck. If only there were a global channel, you would tell everyone in the Cosmos who's trying to find this book.
- But it's just an ordinary book, intriguing in its content but hardly worth breaking into the Shackling Prison for... This only deepens the mystery — who took this book away? And for what reason was it confined within the shadows of the Shackling Prison, hidden from the world's view?
- Perhaps finding the answer to this question will not give you a real sense of accomplishment, but having an unsolved puzzle in your mind makes you uneasy. Just as the new prison guard has suggested, it's time to look for Chiyi.
- (Talk to Chiyi)
I found this book, A Study into the Mara-Struck, in the prison...- Chiyi: What's so special about this book?
- This book had been searched by folks everywhere but no one found it, and it had been concealed in this prison without anyone knowing... You recount the tale to Chiyi, and she listens with comprehension.
- Chiyi: If I were to take into account these two incidents, it seems to suggest that no one was able to find the book due to its confinement within the prison.
- Chiyi: However, it's clear that this is merely a coincidence. The Shackling Prison will not take in an ordinary book for no reason — indeed, we confine only those books of peculiar and perilous nature. They are not to be handled lightly or allowed to be taken away so easily.
- Chiyi: Hence, I believe the book is near the prison for other reasons.
Perhaps it was left behind by a prison guard?
- Chiyi: Maybe it was left behind by a careless guard, and no one has reported it as lost until today.
Perhaps it was left behind by a prisoner?
- Chiyi: All prisoners go through a rigorous checking process for their admission and transfer, and their belongings are registered, so this is not possible.
- Chiyi: (Trailblazer), have you thought of other possibilities?
There are numerous possibilities in this world...
- Chiyi: Exactly. It's frequently remarked that destiny's possibilities resemble a complex web, yet upon closer inspection, it seems more akin to a single thread — if only this book can speak, maybe it could unveil the secret of that thread. Alas, it can't.
Even if we discovered the secret, it would only satisfy our curiosity now.
- Chiyi: Didn't you look for me to satisfy your curiosity?
- Chiyi: Indeed, I'm unable to provide (Trailblazer) with a satisfactory answer. Even within the confines of the Shackling Prison, ordinary inmates maintain a degree of constrained autonomy. Hence, it's not impossible that this book was authored by an inmate within the prison walls...
- Chiyi: Strange things often happen in the Shackling Prison, and as a Jailer, I have seen too many unexplainable things. Even if I were to turn a blind eye, I couldn't convince myself...
- Chiyi: As such, I recommend adopting the "principle of parsimony" — when you have multiple inferences competing in your mind, go for the simplest one... Maybe it's not necessarily the truth itself, but it may be the most compelling inference.
- Chiyi: So, (Trailblazer), close your eyes and focus on what's on your mind.
- ...When you first boarded the Xianzhou, your data bank had persistently notified you of numerous titles yet to be acquired... Despite the varied motivations of those who sought the book, whether deliberate or inadvertent, none succeeded in locating A Study into the Mara-Struck.
- ...Moreover, The Shackling Prison is a place for dangerous offenders. You witnessed some non-human criminals in this prison... so it seems plausible that a book would be locked up here.
- Chiyi recommends the "principle of parsimony," hoping you'll cut through the clutter and find a more concise conclusion. In that case...
This book must have been arrested.
- While this reasoning may seem fantastical, it holds a succinct truth. The book committed a crime and was captured. It should have appeared sooner, yet fate plays a cruel joke on it. It was confined in The Shackling Prison, a place you couldn't access at first...
This book was left behind by a prisoner.
- The cell is for prisoners. Books aren't prisoners, so the book must have been left behind by a prisoner near the cell. As for how the book came into the possession of the prisoner... that'll further complicate a simple question.
The designers forgot to put it in that game.
- Shh!
- Are you suggesting they left it out of the version that officially went live, failed to fix it in time in later versions, and then waited until now to pass it off with an excuse that "the book got arrested"?
- All right, based on the "principle of parsimony," this is not impossible! As such, they have prepared a small gift for you as compensation. Please accept it and never mention this incident again.

- Chiyi: It appears you've obtained a sufficiently straightforward answer. I understand the effort involved in pursuing this matter. As a jailer, I will reward you for your effort and dedication to knowledge! Thank you for your hard work!
