After saying those words to Lothur, Sofie stopped the bleeding in that man's body to prevent something worse.
He was a mortal from this cultivation world, so his anatomy was not so different from that of earthlings. Thus, he could not afford to lose too much of his blood, or he would have weakened gas transport in his body.
Then, before fixing the 'mess' in his body, a doctor would have to prevent bleeding to ensure the integrity of the tissues in his body.
That was not a difficult job for a doctor with spiritual cultivation, so Sofie quickly managed to stop the different bleeds in that body.
In part, she used pressure to temporarily stop the blood from continuing to leave that body, but she also used some pills.
