The Heavenly Realm's Little Purchasing Agent in the 1980S

Blurb One: When Qiao Chuyi returned to the 1980s, she felt no joy at having been given a new lease on life, because she'd been sent to save the world! As a bonus, she got a phone to run errands and do some part-time shopping on behalf of the immortals in Heaven. Ding! Chang'e has received the coat you scanned and mailed through QQ. In return, she sent you a Beauty Pill and a Height-Boosting Elixir! Ding! Zhinu is willing to take you as her disciple and has gifted you a packet of 'Darksteel Embroidery Needles'! Ding!

She could help the heroine guard against the reborn villainess's schemes while nervously keeping the world's order intact. But! (╥_╥) Why was the original male side character, a soldier with long legs, interested in her? And so, whether to give in or not became the dilemma of the century. Premise:
