Han Feng, an avid gamer, wakes up in the dangerous world of Teyvat after an all-night session of Genshin Impact. Facing Hilichurls, the Abyss Order, and the scheming Fatui, his survival seems uncertain until the 'God-Level Manga Shop' system binds to him. Granted absolute invincibility within his store and the ability to grant customers real-world rewards from manga pages, Han Feng opens the 'Carefree Bookstore' in a quiet Mondstadt alley.

The catch? Reading a single chapter costs a staggering 100,000 Mora. Initially dismissed as a scam by locals, the shop's fate changes when the Traveler, Lumine, and Paimon stumble upon it.

Tempted by the promise of obtaining legendary items like the Gourmet Tablecloth and gaining strength to find her lost brother, Lumine takes the gamble. As she dives into 'One Piece' and 'Cardcaptor Sakura,' the boundaries between fiction and reality blur, offering powers that could shift the balance of the seven nations. With a system that rewards customer volume and a protagonist who knows the future, Han Feng is ready to turn Teyvat into his personal fanbase.
