Qingyu has always remained silent about Luo Yirui's matter, and Jing Changle, unless necessary, certainly wouldn't reveal this secret.
The reason it was revealed was that Aunt Bei agreed, you could even say she instructed it.
This is also why he respects Aunt Bei so much; he never realized Aunt Bei has been observing the Pengge Sect from the beginning, thoroughly understanding the internal factions over the years.
So after the rehearsal, Aunt Bei told him that Leng Qingyi could be brought in.
Because he was bound to ally with Qingyu, Aunt Bei sold out this kid Luo Yirui; after all, he didn't care himself.
Luo Yirui's strength is just the tip of the iceberg for Qingyu, but enough to make Leng Qingyi earnestly form an alliance with Qingyu.
Beisitian also had her considerations. After all, she watched the child grow up. If those below slackened due to ignorance of Qingyu's strength, it could easily lead to a bad chain reaction, so it's better to let the other side be convinced.
