Dugu Qiubai. So, I did not know this going into translating this chapter, but Dugu Qiubai is apparently a character from some of the wuxia novels (The Return of the Condor Heroes, The Smiling, Proud Wanderer and The Deer and the Cauldron) by the Hong Kong writer Jin Yong, one of the most famous writers of the genre. I actually believe he was still alive at the time this particular chapter of the manhua was published. Dugu Qiubai in the novels is an invincible swordsman that no one can defeat - exactly like the Dugu Qiubai in the manhua suggests. The technique he mentions is one of the most powerful martial styles in the novels, though I believe it’s not the one Dugu Qiubai used.

Da Gou Bang technique - as mentioned before, the technique mentioned in some of the novels by Jin Yong, literally means… “Dog Beating Stick” technique. I’m sorry, I haven’t read the novels, so that’s all I can tell you.
