Dialogue

Icon Dialogue Commission Check the DM from Kousaka

There seems to be something wrong with the Three Gates' cement mixer... Let's go check it out.
(Receive a DM from Kousaka)
Message Default Boy 02 Icon
Sorry to interrupt. I'm Kousaka, and I suppose you remember me?
Icon DMs REPLY
I think so?
You are...?
Message Default Boy 02 Icon
Please don't kid around with me
Message Default Boy 02 Icon
It's me, leader of the engineering team at Three Gates Corp... We've met before
Message Default Boy 02 Icon
I commissioned you to go to Belobog Heavy Industries and inquire about intelligence mods for the cement mixers
Icon DMs REPLY
I remember now
Yeah...
Message Default Boy 02 Icon
After you left, our technician modified the cement mixer
Message Default Boy 02 Icon
The work is done, but things have become... pretty weird!
Icon DMs REPLY
Weird?
Did the mods fail?
Message Default Boy 02 Icon
I'm not sure what's the problem, either...
Message Default Boy 02 Icon
Please, if you have any free time these days, come check out the site!
Icon Dialogue Commission Tracked Find Kousaka and ask how the cement mixer modifications are going

There seems to be something wrong with the Three Gates' cement mixer... Let's go check it out.
(Idle)
Kousaka: I really didn't see that coming...
(Talk to Kousaka)
Kousaka: Great, you're finally here... We just got the cement mixer to calm down.
Icon Dialogue Talk What happened?
Kousaka: I—I found someone to help recover all those scrapped Belobog logic cores and installed one in our cement mixer...
Kousaka: And all it did was start talking in this weird tone. It wouldn't listen to any commands whatsoever!
Kousaka: What now, what am I gonna do!?
Icon Dialogue Talk You made your own bed!
Icon Dialogue Talk You knew this would happen but still went ahead and did it...
Kousaka: I'm so sorry, I never expected things to turn out like this!
Kousaka: I'm just trying to cut costs and help the engineering team get a bigger end-of-year bonus. But now, I have no idea how I'm supposed to report back to my boss...
Kousaka: Please, ask Belobog Industries for help and see if they know how to stop the modification!
Icon Dialogue Commission Tracked Figure out a way to restore the cement mixer to normal

Kousaka used a scrap logic core to upgrade the cement mixer, but now it's out of control... We've got to come up with a way to get it back to normal!
(Idle)
Kousaka: It's over...
(Interact with the Cement Mixer)
Cement Mixer: (The cement mixer is motionless. Its indicator lights inside are left aglow.)
Icon Dialogue Talk Check carefully
(The cement mixer seems to have detected someone is approaching and starts talking.)
Cement Mixer: Ding— Intelligence modification in progress. Please select a tone you prefer from the following: Proud and sassy, assertive and bossy, or childlike and friendly.
Icon Dialogue Talk Proud and sassy?
Cement Mixer: Ding— Logic core configured.
Cement Mixer: Oh, it's you. What's wrong? Don't get it wrong. I'm not waiting for you here, just prepping for work as scheduled.
Icon Dialogue Talk Ummm, please stop the modification
Cement Mixer: We've just met each other for the first time, and you already think I'm not good enough?!
Cement Mixer: You... You're an idiot!
Icon Dialogue Talk Assertive and bossy?
Cement Mixer: Ding— Logic core configured.
Cement Mixer: Hmmm, coming all the way here to see me, you must be up to something, right?
Icon Dialogue Talk Ummm, please stop the modification
Cement Mixer: Oh? You want me to give up thinking...
Cement Mixer: Guess it seems to you I'm only a dim-witted construction machinery.
Cement Mixer: How merciless...
Icon Dialogue Talk Childlike and friendly?
Cement Mixer: Ding— Logic core configured.
Cement Mixer: I—Is there anything I can help you with? I'll do my best!
Icon Dialogue Talk Ummm, stop the modification
Cement Mixer: Eh? Stop the modification? But I don't remember the logic core's abort command, I can't stop it now...
Cement Mixer: S—Sorry! My memory must be too low, I'm too dumb!
Cement Mixer: (Seems like there's no way to stop it... Let me get some help from Belobog Industries...)
(Interacting with the Cement Mixer again repeats the same dialogue)
Icon Dialogue Commission Tracked Go to Belobog Heavy Industries for technical assistance

The cement mixer can't stop. Best go to Belobog and find a technician to help.
(Idle)
Grace: *Yawn* I'm so sleepy...
(Talk to Grace)
Grace: Eh? It's you. It's rare to see you *yawn*...
Grace: ...around here!
Icon Dialogue Talk Are you okay, Grace?
Grace: I'm okay. I'm just a little sleep-deprived from working on a technical problem for the entire night.
Grace: At times like this, I wish I had a prosthetic arm that can work for me while I'm sleeping!
Grace: It'd be nice if the arm had a muscular-looking and exquisite design! It would be perfect for technical workers.
Grace: So, what can I do for you?
Icon Dialogue Talk It's kind of embarrassing for me to say...
Icon Dialogue Talk I need to ask for a favor...
(Tell Grace about the modifications Three Gates applied to their cement mixers.)
Grace: Do you mean Three Gates used our discarded parts in violation of the regulations and caused some machines to malfunction?
Grace: You're such a nice person, Proxy. But I can't see why Belobog Industries should clean the mess caused by their competitor.
Grace: That being said, I have a fair proposal. If you can provide me with inspiration for my mechanical hand, I'll consider giving you the solution to the core failure.
Icon Dialogue Talk Let me see what I can do!
Icon Dialogue Talk I'll take care of it!
Grace: A sleek and exquisitely designed mechanical hand... I think I saw something like that while shopping on Sixth Street.
Grace: Why don't you take a look around Sixth Street and see if you can find any traces of that mechanical hand?
Grace: How's it going, Proxy? Wasn't too difficult, I hope?
Icon Dialogue Talk I've started to piece some things together.
Icon Dialogue Talk There's no dealing with you.
Grace: Then it's a deal. Give me a photo of that mechanical hand, and I'll give you the solution in exchange.
Grace: I'll get hyped up while I wait for you!
(Idle)
Grace: Wake up!!!
(Talk to Grace again, optional)
Grace: What kind of structure would it have?
Icon Dialogue Commission Tracked Get Enzo's permission and take the photo

As a gesture of goodwill for the "solution," Grace asked us to help her get a photo of Enzo's mechanical arm. We'll need his permission first.
(Idle)
Enzo: My shoulder has been feeling rather heavy recently.
(Talk to Enzo)
Enzo: Hi there, do you have anything to modify?
Enzo: You might have to wait for a while as I need to stretch my arm. It feels a bit stiff after a long day of work.
Icon Dialogue Talk My friend is a fan of your arm!
Icon Dialogue Talk My friend needs your arm!
Enzo: What? My arm? I earn my living with it, so it's not for sale.
You briefly explain Grace's request to take a photo of Enzo's arm.
Enzo: Hahaha! I see. You only want a photo of my prosthetic arm!
Enzo: Sure! It used to give me so much pain, but now I'm proud of it! It was designed by an old friend!
Enzo: It is flexible, strong, and easy to use! The shoulder part feels heavy recently, but I guess it's because I've been overusing it.
Enzo: By the way, did you say you wanted to take a picture of my arm for your friend?
Enzo: Go ahead. I'll stand still.
Icon Dialogue Commission Tracked Take a photo of Enzo's arm

Got permission from Uncle Enzo to take a picture of his arm.
(Idle)
Enzo: Should I change my posture?
(Talk to Enzo again, optional)
Enzo: If your friend is truly interested, she's welcome to come here and look at my arm herself!
Enzo: This arm is the most charming when it is at work!
(Take a photo of Enzo)
Icon Dialogue Commission Tracked Give the photo to Grace

We've got the picture Grace wants. Let's give it to Grace and get the "solution" to stop the cement mixer modification.
(Idle)
Grace: What kind of design would it be?
(Talk to Grace)
Grace: Hey, you're back! Have you snapped a picture of the prosthetic arm? Please show me!
Grace: Yeah...
Grace: Oh!
Grace: Interesting...
Grace: Oh...?
Grace: Is this gentleman experiencing discomfort around his shoulder lately?
Icon Dialogue Talk How do you know that?
Icon Dialogue Talk I think he did mention that earlier.
Grace: This is exactly what I expected...
Grace: This prosthetic arm has a brilliant design, but the bearings at the joints are slightly worn out. Look here...
Grace: This will result in a slight imbalance in its weight distribution. While it can still work, I believe it will cause some discomfort.
Grace: You can remind him of that when you got some time!
Icon Dialogue Talk That's impressive, Grace!
Grace: I feel more energized now after looking at the great mechanical design.
Grace: Given the sincerity of their offer, I'll lend them a hand.
Grace: I brought out those Logic Cores from the Hollows. Most of them had defects and didn't pass testing.
Icon Dialogue Talk Defects?
Grace: Yeah. Ether corrupted their core circuits, and their algorithms became quite strange, no matter how their personalities were programmed.
Grace: When testing these logic cores, we tried out some mods on a forklift. Anton randomly made up a character called: "Real Bro In Pursuit for Power."
Grace: In the end, the forklift just stayed in one place lifting heavy metal objects up and down and refused to carry any freight or take any machine oil...
Grace: It would just say, "I'm only doing strength training now, no cardio, and definitely not having carbs... Otherwise these muscles won't pop."
Icon Dialogue Talk But forklifts don't even have muscles!
Icon Dialogue Talk It's a world I don't even pretend to understand...
Grace: Right? That's why those logic cores didn't pass basic testing, and we scrapped them all.
Icon Dialogue Talk How can we restore the modded cement mixer back to its original state?
Grace: The solution is pretty straightforward. My preset voice command is the only thing needed to shut everything down...
Grace: Just say, "calm down, little one" to the machine. This will make the Logic Core shut down.
(Talk to Grace again, optional)
Grace: I'll keep this picture and look at it whenever I feel sleepy!
Icon Dialogue Commission Tracked Stop the cement mixer's modification process

Grace gave you a voice code that can stop the modification process. Go to the cement mixer and try it out.
(Interact with the Cement Mixer)
Cement Mixer: (The cement mixer is motionless. Its indicator lights inside are left aglow.)
Icon Dialogue Talk Check carefully
(The cement mixer seems to have detected someone is approaching and starts talking.)
Icon Dialogue Talk Let it keep updating and then see what happens
Cement Mixer: Ding— Intelligence modification in progress. Please select a tone you prefer from the following: Proud and sassy, assertive and bossy, or childlike and friendly.
Icon Dialogue Talk Proud and sassy?
Cement Mixer: Ding— Logic core configured.
Cement Mixer: Oh, it's you. What's wrong? Don't get it wrong. I'm not waiting for you here, just prepping for work as scheduled.
Icon Dialogue Talk Ummm, please stop the modification
Cement Mixer: We've just met each other for the first time, and you already think I'm not good enough?!
Cement Mixer: You... You're an idiot!
Icon Dialogue Talk Assertive and bossy?
Cement Mixer: Ding— Logic core configured.
Cement Mixer: Hmmm, coming all the way here to see me, you must be up to something, right?
Icon Dialogue Talk Ummm, please stop the modification
Cement Mixer: Oh? You want me to give up thinking...
Cement Mixer: Guess it seems to you I'm only a dim-witted construction machinery.
Cement Mixer: How merciless...
Icon Dialogue Talk Childlike and friendly?
Cement Mixer: Ding— Logic core configured.
Cement Mixer: I—Is there anything I can help you with? I'll do my best!
Icon Dialogue Talk Ummm, stop the modification
Cement Mixer: Eh? Stop the modification? But I don't remember the logic core's abort command, I can't stop it now...
Cement Mixer: S—Sorry! My memory must be too low, I'm too dumb!
Cement Mixer: (Seems like there's no way to stop it... Perhaps I should try using Grace's voice command.)
Icon Dialogue Talk "Calm down, little one!"
Cement Mixer: Beep— Abort command detected. The logic core is now disabled.
(Phew... You finally manage to make it stop. Go tell     [sic] Kousaka.)
Icon Dialogue Commission Tracked Tell Kousaka that the cement mixer is back to normal

You got the password from Grace to terminate the mod program, and the cement mixer is finally back to normal... Better update Kousaka on the news.
(Idle)
Kousaka: *sigh*... I won't go randomly salvaging things ever again...
(Talk to Kousaka)
Kousaka: How did it go? Did you find a fix?
Icon Dialogue Talk It stopped!
Kousaka: That's great! When the technician gets here, I'll have him dismantle that logic core!
Kousaka: *sigh* Now I'll never mess with these smart machines again... Let's forget about the modding...
Kousaka: Anyway, thanks a lot for your help! I owe you a big one!
