  • Her Experiences

    When I think back to that night, I still feel a little embarrassed. It was midnight, and I went to the cafe to get some water. I unexpectedly found a giant fish on the counter, still flopping around. "This is no good," I thought. I wasn't about to let a free grilled fish steak get away. I pounced on the fish... only to find out that it wasn't a fish, but a person with a fish tail! "Captain Yuebai! Sorry!" "Children who stay up late instead of sleeping will be taken away by weasels." "Weasels?" "Weasels have long tails and like to sneak into houses at night to snatch children who won't go to sleep. Huh? Vice, your tail..." "Ahhhhhh! I'm not a weasel! And don't let the weasels take me away either!" I ran off with my tail in my arms... Later, I learned that Captain Yuebai had been squatting on the ground to measure the Colossus. She felt that the Colossus was very similar in structure to a ship and wanted to study it, but as the cafe was always packed during the day, she had to go at night. Phew... I'll sleep earlier in the future. Eastern legends are so scary!

    —Vice

    Her Story (I)

    You want to know what that thing is hanging from behind me? It's a fishtail. When I was born, this serpentfish tail was just there. Most people feel a bit frightened when they see it. If you don't feel scared, I guess that means you're quite courageous. Serpentfish are a species that lives deep beneath the sea, and according to the legends, they're closely related to the dragons. In Longzhou, we worship dragon totems and naturally regard serpentfish as a symbol of good luck. Fishermen occasionally catch them and throw them back into the sea to receive the ocean's blessings. My family used to be low-level members of the Lin Guild, but because of my serpentfish tail, we were propelled to an elite status in the guild, and I was seen as a miracle child of the Lin family—a once-in-a-century talent, which also made me rather popular with the other kids. What's that look on your face for? Did I say something wrong?

    Her Story (II)

    Don't touch it! My bone dagger is very sharp—you'll cut yourself. This Ancestral Bone Dagger was given to me by an elder of the Lin family and is, of course, very valuable. They gave it to me because I'm so naturally gifted. The elder came in person to gift me this dagger just after I was born. At that time, hundreds of people from the Lin family gathered at my home to see my serpentfish tail. Even the Lin Guildmaster was there. When the elder took out this dagger, everyone was amazed. As I grew older, the elder often took me to see the guild's ships and taught me to carve gadgets and ship parts out of wood. But the good times didn't last long. My father was a man who lived beyond his means, and soon he ended up owing money all over town. In order to pay off his debts, he also committed the cardinal sin of the business world—he sold fake goods. After he was found out, we were banished from the Lin Guild.

    Her Story (III)

    After we were banished, my mother's health took a sharp turn for the worse, and she passed away soon after. My father never recovered. What are you saying sorry for? You're not the one who caused my family's downfall. You're worried about me? I'm fine—I just ate two bowls of river snail noodles, don't worry. I was still young then and told myself that life would improve. However, even when we had nothing left to eat, my father didn't try to find work. Instead, he took my Ancestral Bone Dagger to the pawnshop. From then on, I knew that I could only rely on myself. Sailing, waitressing... I have worked the lowliest of jobs. I told myself in my heart, "I will earn back all the things I have lost, one by one." But when I had finally saved up enough money to buy back my dagger, I realized that my father had stolen my money.

    Her Story (IV)

    When I stood at the pawnshop door and saw only a piece of paper in my purse with, "I'll get back on my feet one day" written on it, I was stupefied. I sat staring into space until dark, intending to continue earning money to save up for my dagger. Just then, the Lin elder walked out of the pawnshop and handed me my Ancestral Bone Dagger. He had secretly been watching me for a long time. The elder intended to take me in, but to avoid causing a scandal, I could no longer use the Lin name. From that day on, I have been known as Mu Yuebai. After this, I worked my way up from the bottom of the Lin family and gradually became the captain of a shipping vessel, transporting cargo to and from Cloud Island. My horizons had been broadened, and my ambition was growing every day. I improved the ships off my own back and raised money to build the luxurious and advanced Shadowind. In the future, I also plan to build the most powerful long-distance ships, open up the safest long-distance routes, and explore places no one has ever ventured.

  • I left a bowl of snail noodles at your door, Navigator.

    Have you ever tried wood carving, Navigator?

    Navigator...

    What do you think of this weapon? It's called a Ancestral Bone Dagger.

    Navigator, last time, you said you wanted to see how cargo purchasing works.

    Greetings. I'm Yuebai, the new captain of The Shadowind.

    Thank you, Navigator.

    The weather is good, perfect for sailing.

    I'm off to eat breakfast. Goodbye.

    Are you awake yet?

    Good morning.

    Good morning. Someone told me you were in the habit of doing morning exercises, is that so?

    The afternoon is absolutely sweltering... I need a shower.

    My, my... The morning has already come and gone.

    It's getting late... I'm going to bed now.

    The sea at night carries a certain magic... A great, but terrifying presence.

    Are you asleep?

    • Tap on the Colossus Room

      The kingdom of Ji possesses unique maritime transport conditions. It is because of this that we managed to develop an advanced trade industry.

      Astra is home to countless unique specialties. I believe both continents can benefit from regular trade and cultural exchanges.

      Traveling the world and interacting with its many nations is the purpose of our guild.

      They're as disgusting as the slimiest of reefs.

      I was adopted by the elder of the Lin family. He is my mentor, as well as my family. One day, I must show him the full extent of my gratitude.

      My family? Mother died, and Father ran away. What else do you want to know? I'm not angry. Really, I'm not. I promise.

      River snail noodles... Delicious.

      I'm not used to sweet and greasy food or dry things.

      Do you think this Colossus can sail on the sea?

      You wish to know what lies ahead? It is an undercurrent, a dangerous reef, a tsunami that will engulf everything. But I chose this road myself and will follow it to the end.

      Ship construction is not easy. It requires the systematic cooperation of shipyards, ports, and foresters. You command people to fight, which also requires coordination between various groups. That is also not easy.

      There's no need for trite greetings, I don't care for them. I came to you to form a friendship.

      Oil its oars, and a boat can row faster. Give a navigator a nautical chart, and a ship can find its way.

      I didn't know you had such a strong constitution. It's impressive that you didn't get seasick and vomit in a storm as violent as the one we encountered just now. I'll take you to the boat race tomorrow, that should be even more exciting. Hmm? Why are you running away?

      You're injured. Hmm, there there. You think I'm too cold? Then take off your clothes. I've just finished working in the sun, and my hands are warm. They're hot enough to help rub some ointment on you.

      When you're free, I'll take you out to sea to hunt a legendary horned whale. You want to go now? No, I must send a boat out to scout things out in advance. I'll call upon you once I've made arrangements.

      You set my pet fish free? Then you can replace it by becoming my new pet.

      I look out-of-sorts? It's probably because I just reprimanded several of my subordinates, the fools. Don't go. You're not one of my subordinates! Don't mind me, just... stand there. By my side.

      Everyone says that the sea is turbulent and ruthless, but it is much easier to face the sea than to face people.

      Although there is a faster way... Forget it. If you want to catch big fish, you must be patient.

      You've been a little down recently. Would you like me to comfort you? Oh, don't be unhappy. I obviously consider you my friend, but I can't bring myself to say those boring pleasantries.

    • Welcoming Dialogs on the Main Screen

      Are you bored? Well, I'm not.

      Want to see the sea in the morning?

      The beauty of the world is akin to a sunset over the ocean.

      Don't go out at night. If you run into an Eclipsite, you'll be done for.

    • Aurorian Trivia I

      I was born with a serpentfish tail. Most people feel afraid when they see it. Oh? You don't fear it, but are merely curious?

    • Aurorian Trivia II

      This Ancestral Bone Dagger was given to me by the elder of the Lin Family twice—once when I was born and once when my father left.

    • Aurorian Trivia III

      My family name is Lin, but I later changed it to Mu. Why? Anyways, let me show you the Shadowind first. I improved its power system recently...

  • Class

    Detonator (S)

    (S+ at BT3)

    Overall

    S (S+ at BT3)

    Advantages

    +Excellent at both mobbing and bossing

    +Damage ceiling that rivals some of the best in water while also having a very competent floor.

    +Teleport on chain can come in very handy when you need the range.

    Disadvantages

    -Damage ceiling requires either BT3 or lots of conversion

    -Many competitive, low-investment alternatives

    Explanation

    Mu Yuebai has an extremely competitive ceiling, but a somewhat demanding investment requirement. In this sense, she’s fairly comparable to Nina – excellent at both mobbing and bossing, but only with strong conversion support or access to BT3. It’s enough to dock points from her overall rating at BT0, though she competes with Regal even at her worst. Still, the fact that she can go blow for blow with Azure counts for something, and even BT0 Mu is an arguable best-in-slot in mobbing maps and secondary teams.
