Catalog only. The chapter bodies were not read. No quoted lines, no free-preview paste, no claim that a welcome row, a restarted chapter 1, or the newest button is the first door.
Search Crazy Upgrade System or level-up system. The Qidian page does not print an English title. The mobile book page is book 1003728666, author 疯狂的萌萌.
There is no 作品相关 shelf. Two titles look like a first chapter. 第一章 苍白少年 is the first story, in the first volume, 正文卷. The next row is 第二章 疯狂升级系统！. The catalog lists 3003 rows. 620.02万 characters is the shelf label. The mobile page said 完本. The newest catalog timestamp is 第1章 新书科幻已发布. The door is the earlier row.
Start at 第一章 苍白少年
Open 第一章 苍白少年 on Qidian and follow that catalog from 正文卷, not from the newest button. The Chinese original, 疯狂升级系统, is the book page. On 15 October 2026 the mobile page called it 完本, author 疯狂的萌萌, category 玄幻·异世大陆, updated 2025-07-21, with 620.02万 characters. The catalog listed 3003 chapters. The public pitch was not copied here.
The newest button is not the door
The newest timestamp points at 第1章 新书科幻已发布. 620.02万 characters is a shelf label, not a dare. You are deciding whether 第一章 苍白少年, filed under 异世大陆, is your door. 完本 is a status. The 番外 bar holds one row, 第1章 新书科幻已发布. That is a new-book ad wearing chapter 1. The story catalog keeps counting: volume 2 continues at 第三十四章 斩杀！, and a later volume opens on 上架感言 before 第两百七十一章 千人敬仰. The finished note is 第两千七百五十一章 完本感言, one row before the ad.
