Lin Yan had known beforehand that this remnant of the Liu Family was to offer a technique, as well as a secret matter.
The technique originated from the Holy Land, a method to eradicate True Qi.
The secret was that each of the six major families within the inner city had an elite group, choosing direct descendants to search all over for Pure Lands, collecting ancient town objects, and seeking all kinds of Secret Techniques.
The reason Liu Yuqing only spoke of offering one Secret Technique was that the second technique didn't seem like it could be cultivated by the Human Clan.
This technique was called Five Mountains Dragon Capture, a close-quarters Combat Technique.
Once mastery of this technique was achieved, with mere physical strength one could shake mountains and capture true dragons, an unparalleled might.
However, employing this physical close-combat technique puts an extreme burden on one's physique!
