She gives in

Mei wanted to change the world and once held enough power to make the difference... but she wasn't stupid, and knew very well her situation.
In the beginning she was too eager to act and let her impatience cloud her judegment, but now that Old Mo poured the cold water of harsh reality upon her burning hot will to act... she realized it was too early.
Sure, she may have regained enough power to beat strong even strong guys among the common murims, but even if she did she would have wasted her cultivation in that single fight and become useless.
And what about elites? If she met any, maybe she'd win only by overdrawing her energy and even then it'd be so only against the average ones.

It was indeed to early to go out in the world.
She could try her hand at fighting this old doctor, but she knew his energy reserves were roughly three times her current ones and unlike her he didn't have any problems with his cultivation.
Hell, she even lost her weapon!

By seriously overdrawing her cultivation she might have a chance... but what use would it be?
Even if she did win and would have Ren at her side to quell the side-effects of the overdrawing technique, she would still have wasted all her current cultivation and would have to start again from zero.
Either way she'd be stuck there, so why even bother?

She sighed and nodded "I understand, we'll stay here and bide our time till we're strong enough"

Old Mo pumped his fist in his mind, while outwardly he only showed stern approval with a nod "Good"
Then he turned towards Ren "From tomorrow your we'll adjust your training regimen. You can now use energy, and need to get used to it"
Su Mei nodded in approval, not knowing Old Mo would take charge of her training too, albeit of a different kind compared to Ren, and all under the guise of medical treatment "Why do you look so complacent? He'll be training, but you won't be idle either. Your cultivation isn't going to repair itself, and we'll be doing some pretty intense treatment if we want to get back in shape any time soon"

The girl heard what he said and blushed, a complicated look appearing on her face.
Previously he said that her pussy was a focal point of treatment due to her cultivation technique's sexual nature... now that he was talking about intense treatment, did he mean he'll be fiddling with her pussy a lot from now on?
She was about to say something, but he interrupted "No question asked, didn't i say it? Win me and do whatever you want, lose and stay here to obediently accept your treatment. You didn't even fight, so you don't have the right to question my orders. Moreover this is my place, so even if you are my disciple's woman as long as you live here you'll have to follow whatever i say. If you object, then first beat me"

He was overbearing, but he was also right.
His house, his rule.

Sure, she could run away... but what would Ren think if they eloped like this?
Moreover, even if they did elope... the old master was right, and they wouldn't last long outside in their current situation.
As embarrassing as it was, it would be better to let Old Mo treat her problem and then go out in the world after she got better and Ren stronger... after all he was a renown doctor, letting him treat her was still better than trying to do repair her cultivation by herself and fail. Too bad she didn't know he was a quack, and while he did have some medical knowledge... when it came to repair cultivations, she may be even more knowledgeable than him.

And that was how that evening came to a close... though before they retired to their own hut, Old Mo took the chance to pull Mei aside and warn "I didn't mention it earlier but... clean yourself properly in the morning, i don't want to see you leak during treatmet. You can have your fun, but if i see you drip even a bit of him i'll take charge of your baths from now on" she blushed and wanted to say something, but he gave her a stern look that showed he meant every single word he said and went back before she could add anything... how embarassing!

So he did mind her leaking cum during the previous examination!
She resoluted herself to wash her pussy properly from now on, but didn't give much thought to his "threat" of taking charge of her baths... too bad he meant every word of it, and even if she did clean properly he'd be sure to slick some of his own cum in her just to give himself the justification he'd need to bathe together!

It was easily to fap quite a lot out, that night like any other night before Ren and Mei went at it like they were the only people in this mountain and Old Mo could hear pretty much everything... hell, he even took the chance to slip out his hut and peek on them fucking like rabbits, dumping all his loads into a jar he prepared and enviying Ren for being able to dump himself into the beauty instead...
