By 'letter to the humans', Guardian Li was naturally saying that they should send a letter to Chen Changsheng.
Guardian Li believed that given the teacher-student relationship between the Pope and the princess, as long as Chen Changsheng knew of this marriage, he would find a way to resolve it. Whether it was a personally written letter or some other method, he could place significant pressure on the Empress, making her think a little before acting. However, for some reason, Princess Luoluo had never agreed. If this were three years ago, one could say that the Pope was too difficult to find, but the entire continent now knew that the Pope had begun to involve himself in the continent's affairs once more and had even taken part in many momentous events.
"Teacher… it's hard to say whether he's had a good time these last few years."
Luoluo softly added, "He still has many things that he needs to do. I'm not able to help him as his student, nor can I add to his troubles."
