Dialogue[]

(Initial interaction)
Boss Du: Welcome, customer. Would you like a mug of ninety-percent strong Flaming Potent Tea?
Icon Dialogue Arrow You need to explain what is Flaming Potent Tea first.
Boss Du: Flaming Potent Tea is a tea that is combustible. I guess I don't have to explain what "tea" and "combustible" mean, right?
Icon Dialogue Arrow Sure! I'm a tea-lover.
Boss Du: Please allow me to remind you that my tea is different from that made by the Sleepless Earl. In case you didn't catch it the first time, I want to emphasize this again — my Flaming Potent Tea is combustible.
(Both dialogue options lead to the following response)
Icon Dialogue Arrow Please elaborate what "tea" and "combustible" mean.
Boss Du lets out a deep sigh.
Boss Du: ...All right. "Combustion" refers to the chemical reaction that occurs between a combustible material and an oxidizer when the former reaches its ignition point.
Boss Du: As for "tea"... it usually refers to drinks made from plants. Different teas vary in taste. Flaming Potent Tea is characterized by its pungent and burning taste, and a unique process of production that includes fermentation and distillation. Therefore, drinking too much Flaming Potent Tea may be harmful to your health.
Icon Dialogue Arrow Alright. Stop muddling. This is alcohol, isn't it?
Boss Du: No, this is tea.
Boss Du: According to the regulations issued by the Realm-Keeping Commission, we can only sell TEA to customers. I hope you can understand, dear customer.
Icon Dialogue Arrow Wonderful! This is exactly what I need.
Icon Dialogue Arrow If you say so.
Boss Du: Good, I can tell that you've understood the essence of Flaming Potent Tea. Why bother with its name, or its true composition? Just enjoy your life and drink away all your sorrows... with tea, of course.
Icon Dialogue Arrow Alright. Stop muddling. This is alcohol, isn't it?
Boss Du: No, this is tea.
Boss Du: According to the regulations issued by the Realm-Keeping Commission, we can only sell TEA to customers. I hope you can understand, dear customer.
Boss Du: Since you're a new face here, please accept this cup of Flaming Potent Tea as a token of my goodwill. It's on the house.
Boss Du: My tea house may be inconspicuous, but the most influential persons in Exalting Sanctum would come here for tea. Of course, you are free to take a seat here and share your stories.

(Continue on to dialogue options below)

(Subsequent interactions)
Boss Du: My hand-brewed Flaming Potent Tea is flavorful and strong! Thank you for you continued visits. Would you like to buy some tea or just have a chat?
Icon Dialogue Shop I'd like to have some tea...
(Opens Du's Teahouse Store)
Icon Dialogue Talk Has business been going well lately?
Boss Du: Thanks to you, it's been going well. Now that the Aurum Alley is bustling with people, my teahouse is garnering fame too.
Boss Du: As you know, my customers prefer a quiet environment, so they don't want the place to get too famous... I understand their requirements for privacy.
Boss Du: Next, I'd like to make full use of the space in my store and limit the crowd through a reservation system to ensure a satisfactory experience for my customers. I'm not capable of serving too many customers at once either.
Icon Dialogue Talk Do you have time to chat now?
Boss Du: To be honest, being the owner of a tea house means you simply have to chat with your customers. So, what would you like to talk about?
Icon Dialogue Talk Sounds like you're good at talking then?
Boss Du: Well, that's not what I said. Conversational skills are far from esoteric and can be easily mastered by anyone.
Boss Du: But, based on my experience, the quality of the conversation is up to the customer. Once my customers had a few cups of Flaming Potent Tea, they'll start telling stories and half-truths. In that case, all I need to do is nod and play along.
Icon Dialogue Arrow You wouldn't lead the conversation? Even subtly?
Boss Du: No, because most gossip in a tea house doesn't deserve any serious attention. It is like stumbling across a precious pearl in the waves of the Lunarescent Depths — Nine out of ten times you would only find rubble and weeds.
Boss Du: You make it sound like some smart person would subtly steer conversations in their favor to get useful information out of other people. Frankly, that's hardly the case here.
Boss Du: I think what really matters in a tea house is not the content of the conversation, but the act of holding a conversation itself.
Icon Dialogue Arrow And now you've memorized all the stories.
Boss Du: Are you implying that I may blabber my customers' secrets to others?
Boss Du: It is inevitable that I hear my customers' deep and intimate secrets. But rest assured, I know well what I'm not supposed to bandy about.
Boss Du: If my words don't reassure you, please feel free to stay silent. As I said, I have no interest in prying into the souls of my customers.
Icon Dialogue Talk Is Flaming Potent Tea popular in Aurum Alley?
Boss Du: Ah, dear customer. You're worried about my business.
Boss Du: Aurum Alley is never short of troubles, and people pestered by them would naturally come to my tea house. If my customers were free of troubles one day, then my business would be busted.
Boss Du: But I wouldn't fret if that happened. Who wouldn't want a world free of troubles after all?
Icon Dialogue Talk Could you share any of your secrets with me?
Boss Du: You know that I am committed to keeping secrets, but still wants to probe...? Fine, but probing has a price, too. Are you willing to share a secret of your own in exchange for one of mine?
Icon Dialogue Arrow (Tell him a "secret" that you just made up.)
Boss Du: So that's how it is, I see. Secrets are nothing more than a few words, yet those words differ dramatically in value.
Boss Du: Then I'll tell you a secret of similar value.
Boss Du: When Foxians sleep, their tails always point in the same cardinal direction.
Icon Dialogue Arrow (Tell him that March 7th would fall down when warp jumping.)
Boss Du: So that's how it is. I can see a romantic customer like you getting acquainted with a girl who tends to fall down for no reason.
Boss Du: In this case, I'll share a cute secret with you, too.
Boss Du: You can tell a Foxian's mood by their ears. When they feel happy, their ears will perk up as if an electric current passed through.
Icon Dialogue Arrow (Tell him the inescapable truth that everything in this universe will eventually fade away.)
Boss Du: ...
Boss Du: Are you really sure you can share such a crucial secret with me?
Boss Du: Well, if this is the case... I'll share a grave secret with you, too.
Boss Du: ...Flaming Potent Tea is called alcohol in some worlds.
Boss Du: It's up to you to believe it or not.
Icon Dialogue Talk You're fond of inventing new flavors of Flaming Potent Tea, aren't you?
Boss Du: Hahahaha, different customers have different preferences, and some of them always want to enjoy flavors they've never tried before.
Boss Du: Add some juice, egg whites, or milk... or even mung bean soda to the traditional Flaming Potent Tea, and you'll create different mixed drinks for different preferences.
Boss Du: If you are interested, feel free to try my latest inventions that are not yet publicly available. Do me this favor and I'll make it worth your while.
Icon Dialogue Arrow You're not planning to hurt me, are you?
Boss Du: Of course not. We are doing the right thing by expanding the known sensory boundaries of Flaming Potent Tea.
Icon Dialogue Arrow Well, it won't hurt, I guess...
Boss Du: Sure it won't. I would even express my gratitude if the development of new products goes well.
Boss Du: You're always welcome to try my inventions when inspiration strikes, dear customer.
Icon Dialogue Exit That's it for now.
Boss Du: My door is always open for you, dear customer.
(After completing Adventure Mission Searching for You: Idle Sips)
Icon Dialogue Talk Would you like a bowl of "Taste of the Sea"?
Boss Du: I'm sorry, guest, "Taste of the Sea" is no longer available as the core ingredient — water from the Lunarescent Depths can't be obtained anymore.
Boss Du: The Lunarescent Depths is a sacred site for the Vidyadhara. Though they used to patrol the shoreline, I was always able to sneak in and scoop up a couple of barrels of water.
Boss Du: But now they've deployed dozens of cycranes to constantly patrol the shore, sounding the alarm at any hint of suspicious activity — leaving no opportunity for us.
Boss Du: We've still got plenty of other delightful teas in the shop — why not have a try?
Icon Dialogue Exit That's it for now.
Boss Du: My door is always open for you, dear customer.
