[Full-Dive] A Blank-Slate Class? But I Master Every Weapon

On the launch day of the full-dive online game Otherworldly Paths, Xia Zhiyu awakened a hidden class: Soulbinder. Three announcements flashed across the screen, and the entire server was stunned. Only then did everyone learn that a so-called hidden class meant its skill inheritance had been lost, it couldn't equip weapons or armor, and there were no clues for its advancement quests... When the news got out, the whole server erupted. "Isn't that just a blank slate?" "The most useless class!" "Might as well delete your character..." Xia Zhiyu listened to the discussions and stayed silent for a long time. He didn't delete his character. Because in his previous life, he had been a Soulbinder! Everything unknown to others was an open book to him. Some time later, everyone realized that this blank-slate class had created a gaming miracle. He got the first dungeon clear, topped the combat rankings, and set the tower-climbing record. He was even part of the guide team for the challenging crafting classes. Was he cheating, or was he an insider? "How do you know so much?" His taciturn friend Z couldn't help asking. Looking at the familiar materials and text, he smiled mysteriously. "Maybe the game developer and I go way back, from another world." Xia Zhiyu had been talking off the cuff and didn't notice his friend's thoughtful silence. That was, until he entered the Tower of Yesteryear, sealed away with the game's first map, and the boss inside awakened the power of the contract within him. Xia Zhiyu froze. There before him was the spirit he'd once contracted?! This wasn't a game. This was his former home! Theme: Fate and responsibility are bound together
