Welcome to the Anti-Fraud App [Infinite]

What would you do when supernatural rules descend upon the world? Baili Jing: Follow the rules to the letter, obviously. What if the rules contradict each other, and it's impossible to tell what's true? Baili Jing: Open the anti-scam app? [Welcome to the Anti-Scam App. In every dungeon, carefully discern and follow these general rules: 1. Do not make loud noises. If you hear screams or calls for help, cover your ears and leave as quickly as possible. 2. If you reunite with a companion after getting separated, ignore them. Do not speak to them! 3. If you encounter any supernatural rules related to the number 404, fend for yourself. No one can escape the Deceiver's trickery, unless "it" has already set its sights on you.] Baili Jing, a rich heiress, firmly believed in all the various ways people entered the infinite-flow dungeons. Yet every call she received turned out to be a phone scam, and every private message she got eventually led to a money transfer request. Finally, after an agent tricked her into renting an apartment, Baili Jing found the "Anti-Scam" app on her phone. The moment she opened it, she found that her dream had come true! (This is a lie.) A high-dimensional game descended quietly upon the world. In its dungeons, it was hard to tell truth from lies, and the rules were bizarre. The 404 known to players as the "Deceiver" never listened to just one side or blindly believed anyone. Even when speaking, it made sure every word was three parts truth and seven parts lies. Then "it" waited for Baili Jing in a dungeon, and from then on, it got a one-way ticket to disaster. Every dungeon was like an ICU, and every plot twist like a roller coaster. She snatched the NPC security guard's black uniform and put it on, yet obediently signed an unfair contract with 404, the owner of the house. She dutifully looked away from the white roses in the botanical garden, then turned around and uprooted every red rose. She obediently waited in place for her friend who got lost in the old town, then carried the friend into the folk customs museum when they reunited... 404: Exhausted. This is the first time I've met a human who refuses to follow the script. Respect. The "Anti-Scam App: Heretic Edition" updated with a new internal rule: [When any dungeon NPC encounters a human who unconditionally trusts everything and follows every rule to the letter, report them to 404 immediately! Also, stay far away from that human! Repeating: stay far away from that human!] 1. An unconventional female lead with an unusual train of thought: obedient and easy to fool, but a force of nature. 2. Everyone has one-sided feelings for the female lead, who shines on her own. 3. Plot-focused, and readers can ship any pairing they like. 4. The characters aren't perfect. Their past experiences shaped their personalities, which serve the story in a believable way. Theme: Honesty and keeping one's word are virtues.
