Lu Sheng smiled at the two of them. From his observation of them during this period, the sisters’ disease seemed to show signs of alleviating after some treatment. It was merely malignant skin diseases. Furthermore, they performed their duties as his personal assistants competently. Lu Sheng gave them many menial tasks to handle after his training sessions, like washing his robes, tidying the place, fetching water…etc. They were fulfilling Qiao’er’s function well, and in fact, better than she could.
Seeing the looks of realization and joy on their faces, an idea came to Lu Sheng’s mind, ‘These two girls have a mysterious background and possess a special ability. Why not lend them a helping hand when they’re down in the gutters to sow a favor?’
After some thought, he suggested, "If you two would like to learn, I can impart you some basic saber techniques, actually. I can tell that you have never learnt any combat skills."
Joy burst out on their faces.
[1] ED/N: I'm pretty sure the ghost escaped, but the raws indeed say "beat to death". Well, it may just be that what looked like escape was actually its demise.
TL/N: Actually it really died! That came across quite clearly to me when I read the raws.
