My bet is on:

That old man is looking for the divine physician as well and the sect os ordered to look for him. After fighting them they get a clue about dp location.

The only known small probable connection to something helping the mc is the item they’re transporting. It wouldn’t be far off if I was a betting man I would bet that the item plays a role and healing the old man. Whether the divine physician is involved or not.

Same , I don't know it's happening Recently too much. . .

He probably means that if he intervenes in the situation, it would inconvenience them. She is one of dragon peak but mc considers her a kind person, from the previous chapters you would know that he doesn't care that she's from dragon peak

Got any idea what it means?

But his master's mind will run off eventually, so the MC needs to rush

ZHONGNAN has a scort agency so they want to destroy the competition aka the dragon scort agency
MC though that Mount Hua could help the dragon agency and stop Zhongnan but it seems that since Mount Hua and Zhongnan are "allies" they will turn a blind eye to what is happening. Still MC will try to talk with the guy from Mount Hua before he leaves. (MC does not want to help because he has to find the healer to save his master)

if someone explains it to you relay that to me as well

who?
