Blurb[]
A precarious balance had existed between the Black Tortoise Promenade and Genryumon in Shanhaijing when an incident throws that balance awry... Will Sensei and the students be able to prevent the situation from plunging into chaos?
“ | Oh, there you are, Sensei. How are you enjoying Shanhaijing? | ” |
~ to Sensei, Visiting |
“ | I'm glad you didn't get lost. The streets of Shanhaijing are complicated. | ” |
~ to Sensei, Visiting |
“ | Haha! Couldn't tickle the truth out of you, eh? I can offer you one of the dishes I'm still studying, but... | ” |
~ to Sensei, Tapping |
“ | I always provide the highest quality food to my guests! And well... If I'm still studying a dish, it might not be at that level yet. | ” |
~ to Sensei, Tapping |
“ | Sensei, you are very important to me. You're a customer and a colleague and...um... Okay, I've said too much. | ” |
~ to Sensei, Tapping |
“ | My shoulders have so stiff lately... I need a massage. Maybe from Sensei...? *gulp* | ” |
~ to Sensei, Tapping |
“ | After all that, we're finished. It's all thanks to you, Sensei. You haven't lost anything, have you? If so, I'll go find it. | ” |
~ to Sensei, Event Ended |
“ | If it isn’t Sensei. Welcome to Shanhaijing. Ah, as a side note… I don’t recommend going to the Xuanwu Merchant Association. | ” |
~ to Sensei, Visiting |
“ | Sensei? Hurry over to Shanhaijing. Oh, and I suggest you steer clear of the Black Tortoise Promenade. | ” |
~ to Sensei, Visiting (Global Version) |
“ | This is Shanhaijing. Heh. Don't let your eyes wander too much. I'd hate for you to get lost. | ” |
~ to Sensei, Visiting |
“ | Oh? You got something to say? Go ahead. There are some days when I just want to tell people what I really think. | ” |
~ to Sensei, Tapping |
“ | Why? We've still got business to finish. And even if its dirty business...somebody's got to do it. Wasn't that a cool line? | ” |
~ to Sensei, Tapping |
“ | Shanhaijing is noisier than usual. Is it because you're here..? | ” |
~ to Sensei, Tapping |
“ | When an incident arises, the first to move are us—the executives. That’s how it is. Now, let’s go. | ” |
~ to Sensei, Tapping |
“ | What an ending...I never imagined... Well... I think things ended well. Good. | ” |
~ to Sensei, Event Ended |
“ | When there are multiple missions, I take care of the simple ones first. That makes things go more smoothly. | ” |
~ to Sensei, Visiting |
“ | Purpose. Duty. Operation. Mission. The all mean the same. | ” |
~ to Sensei, Visiting |
“ | If you feel overwhelmed by your everyday work, please tell me immediately. | ” |
~ to Sensei, Tapping |
“ | The contents of this are supposed to be difficult, even for the members of the Xuanlong Office, and yet… Color me surprised, Sensei. | ” |
~ to Sensei, Tapping |
“ | You really did it, Sensei! I knew I wasn't wrong about you. | ” |
~ to Sensei, Mission Cleared |
“ | You've been taking on difficult missions like a pro. B-But...! Any Genryumon member can do that! | ” |
~ to Sensei, Mission Cleared |

Event 25 - Guide 5Category:test
“ | We're known for our food... But the main work of the Black Tortoise Promenade is commerce. You can leave product management to us. | ” |
~ to Sensei, Visiting |
“ | Of course, product sourcing and distribution are important... But so are presentation and the layout of your goods. Take your time and look carefully. | ” |
~ to Sensei, Visiting |
“ | Hm. What's wrong? Are you concerned about something? | ” |
~ to Sensei, Tapping |
“ | Just let me know if you need anything. ...I'll buy the right one next time. | ” |
~ to Sensei, Tapping |
“ | Do you want that one? A good pick. Quality guaranteed! | ” |
~ to Sensei, Exchanging |
“ | As you probably know, Sensei, there's no such thing as a free lunch. If a product you use or consume is free... All that means is you've become the product yourself without even knowing! | ” |
~ to Sensei, Exchanging |
“ | Make your purchase before it's sold out. There's nothing worse than waiting for the next shipment. | ” |
~ to Sensei, Exchanging |
“ | Thank you as always! It's been awhile since I saw the store. Haha. | ” |
~ to Sensei, Exchanging |
“ | Things have been taken care of, but I plan on continuing the store for a while. It's important to always finish your work. | ” |
~ to Sensei, Event Ended |

“ | Sensei! It’s time for you to test your luck. | ” |

Trivia[]
- The event title is based on the Japanese idiom 呉越同舟, which is a yojijukugo (四字熟語 - lit. four-character compound) meaning bitter enemies in the same boat or rivals finding themselves together by chance. The first part of the idiom consists of the characters 呉越, which refer to the Kingdoms of Wu and Yue, respectively, from ancient China, who were arch-enemies. The event title replaces these characters with 龍武, which are characters from Xuanlong (玄龍) and Xuanwu (玄武) respectively. This effectively creates a new yojijukugo with the same essence, as Xuanlong and Xuanwu are rivals, much like the Wu and Yue Kingdoms were.
