Ever since she was given permission to leave, Nightingale started packing up, assigning Tangmo and Baiyue to stay behind and conduct research. Magic Messenger Rune on Luo'er's hand was initially connected with Nightingale, but because she was also about to embark with the Advance Team, she had to replace the connected object.
This time, despite being quite confident, Tangmo didn't have the opportunity to connect to Luo'er as a messenger. In contrast, it was the quiet Baiyue who got the chance. Perhaps Nightingale felt that Tangmo's personality was too lively, worried that she would trouble Luo'er without reason, hence didn't dare to assign her as a liaison officer.
