The Traveler Is Livestreaming

[Not abandoned, but updates are whenever I feel like it. This is a free labor-of-love story! It may be a very, very long time before inspiration strikes again... Everyone, gomennasai! (prostrates) I'll try to finish it (try).] On the first day of their journey into a new world, the Traveler inexplicably got bound to a livestream System. All the features were locked from the start, with only the basic livestream room left available. The Traveler and their younger sister looked at each other, then launched their livestreaming careers, full of curiosity about how it might change their lives. - As a livestream room that suddenly appeared in Bilibili's recommendations, "Traveler" didn't attract much attention at first. That was until four in the afternoon, when a trending topic quietly caught people's eyes. #TheDimensionalWallCanActuallyBeBroken# Onlookers: People still use that joke these days? Let's go see what's happening! And so they all rushed in, one after another, and never came out again. (Not really.) - On a starry night, with the moon bright in the sky, the Traveler stood blankly beneath a tree, holding their sister's hand in one hand and a blade in the other. [Go on, Aether! Cut that scumbag boss down!] The Traveler flashed forward, and Muzan's head hit the ground. On a busy street, the Traveler was holding a crepe they'd bought for their sister when they exchanged a glance with a Russian friend in a felt hat. [You can turn in that Russian guy in front of you for a reward!] With a cream-filled crepe in their mouth, the kindhearted Traveler escorted the kindhearted Russian to the police station. At an amusement park, they ran into an amnesiac woman playing with children. The sister kindly asked if they should call the police. [It's Curaçao! Aether, hurry and pull Lumine back! Someone's watching her right now!] The Traveler was horrified, and punched the Black Organization into the ground, where they couldn't get back up. Later, the Traveler took their sister's hand and set foot on the continent of Teyvat. - No romance. Aether is loved by everyone. Although this is a livestream story, there isn't much livestreaming in the early chapters. The worlds aren't closely connected, so you can skip around. - 'Welcome to the world.' Theme: The whole world will open its doors to you.
