800 Yuan Bought a Cultivation World

He Yu, suffering from a terminal illness, uses his last savings to buy a mysterious glass jar, accidentally connecting to the Xuan Yuan Realm. By transforming into the 'Sky-Blocking Great Emperor' using mundane items like toothpicks and batteries, he repeatedly saves Qing Lei Sect disciple Luo Qingyi. Through cross-dimensional collaboration, he helps her resist half-demons and revive the sect, while she unlocks his cultivation powers and turns their desperate situation around. From the antique street to Wanyin Mountain, and from the calamities of the Xuan Yuan Realm to their reunion in reality, this magical bond born from a glass jar will ultimately write a legendary cross-generational romance and a story of triumph.
