Luo Qingjin is Luo Qingchuan's cousin. She was originally engaged in some strange flower and plant poison research in Dr. C's laboratory. She has made some achievements and has quite the demeanor of a doctor. Dr. C found her a month ago and told her that her cousin, Luo Qingchuan, had traveled to the Qing Dynasty. Naturally, she had no reaction, but Dr. C ordered her to find Luo Qingchuan and ask her to travel through time, otherwise he would threaten to throw away her flowers and plants. She was definitely reluctant to let go, so she shouldered the mission to find a way to travel through time, and miraculously traveled through it.
