cover art by Duy Phan Rebuild your life, 1 cc of mana at a time. Jordan Yu is your typical high-achieving burnout. He's going nowhere fast, especially when he spends all his time obsessing over Vesselia: a spellcasting RPG where your mana capacity is the definitive measure of power and status. Everything changes when Jordan is transported to Vesselia’s game world, armed with OP perks to kick-start his run. Maxed-out levels, gods whispering advice in his ear, and best of all the Heavenly Cauldron: a unique Vessel boasting the highest mana capacity in the game. A fresh start. A chance to live out his ultimate power fantasy. The only catch? The cauldron won’t let him cast any spells until it’s first filled to the very top. All 1,000,000,000 cc of it. Left spell-less in a world of spellcasters, Jordan must grit and grind for every scrap. They say you get out of life what you pour into it. Jordan will put that—and himself—to the test, 1 cc at a time. What to expect: - Real dice rolls. I honor every result and write the scenes accordingly. Good luck can sometimes be a shortcut to success, but bad luck is never a guarantee of failure. - “Stats that talk” as inspired by Disco Elysium. - While there are some combat scenarios, the MC himself isn’t built for it. Problems are often solved via dialogue, workarounds, and sheer hard work. Progression is internal as much as systemic. - Heavily homebrew D&D adapted to an eastern fantasy setting. - Feels go brrr (and sometimes numbers too). - Slow-burn romantic subplot (no harem). Release schedule: - 5 chapters per week (M-F) - 30+ chapters of backlog at all times
