It's not that he lacked compassion, he was simply a fellow disciple, ah, it should be the Immortal Sect's responsibility to rescue her!
These women didn't go to the Immortal Sect, instead, they followed the two senior brothers to his place!
Perhaps it was because they were just frequently active disciples of the Outer Sect, the Immortal Sect wouldn't pay much attention to them, as thousands upon thousands die on missions, the cultivation world is so ruthless, only those who survive and prove capable are valued.
Even if it were some elite disciple who initiated a plea for help from the Immortal Sect, they could only seek aid from their immediate management.
There wouldn't be an entire Immortal Sect's worth of Capable Beings coming to their aid, as everyone was striving for cultivation, and the higher-ups wouldn't exhaust themselves for the sake of their disciples.
