When Zhang the Heavenly Master said this, his heart felt indescribably painful.
In the exchanges and discussions among the Daoist sects, there are usually gains and losses. It's hard to say who gains more from whom; only when receiving a great gift would one invite other Daoist friends to bear witness.
In the days when Dragon Phoenix Mountain was thriving, it was always the smaller Daoist sects elsewhere asking others to witness—claiming they were taught by or recognized by Dragon Phoenix Mountain, so they could preach under the banner of Dragon Phoenix Mountain thereafter.
A mere two sets of martial cultivation techniques, back in those days, Dragon Phoenix Mountain would have accepted with perhaps just a word of thanks and returned a small gift, and that would be the end of it.
Now that he's receiving two sets of cultivation techniques, he has to invite others from the same path to witness this; it's truly unworthy of the name "Dragon Phoenix Mountain."
