From the Start, I Had Iced Tea, and I Conquered the Immortal Realm with It

One-on-one, happy ending, both leads devoted only to each other [Warm-hearted, money-loving sunshine tea fairy vs. seemingly cold, actually tender, tragically beautiful and lazy Spring God] [Transmigration / Golden Finger / Feel-Good Story / Face-Slapping and Punishing Scum / Healing / Sweet Romance / Love Grows Over Time] Shen Miancha transmigrates to the immortal realm and becomes a tea fairy with barely any spiritual power. She can’t earn spirit stones or afford a place in an immortal palace, and all the immortals laugh at her as the most good-for-nothing ascender. That is, until she pulls a bottle of iced tea from her pocket. A badly wounded immortal lord drinks it and recovers instantly; an Immortal Venerable stuck at a bottleneck drinks it and breaks through on the spot! The Three Realms go wild, and gods and demons bid against one another for her. But Xie Chunci, the unscrupulous landlord who treats her like an iced-tea supplier, lazily catches her wrist. “Little tea fairy, your tea can save all living beings, but can it save this heart of mine, which has long since fallen for you?” One day, Shen Miancha casually asks, “I heard certain ancient deities can heal themselves by drawing near to the life force around others?” Xie Chunci lazily lifts his eyelids and glances at her. His voice is as languid as ever, though he draws out the last few words a little longer. “Mm. And?” Shen Miancha shakes the teacup in her hand, smiling brightly. “So, should someone who sneaks over every night to ‘recharge’ have to pay a little ‘electricity bill’?” Xie Chunci: “…” He falls silent for a moment, then suddenly reaches out and catches her wrist with precision. He gives it a tug, pulling her toward him. Lowering his head, he leans close to her suddenly flushed ear, his warm breath brushing against it. “I’m practically yours, body and soul. What more ‘electricity bill’ could you want, hmm?”
