The game designer, wary of original author enthusiasts like Yin Bukui and Sheng Tianbanzi, made many changes to opportunities described in the original works to prevent players from easily obtaining them. For example, finding Jiuyang in the Shaolin Sutra Pavilion or Beiming in the Langhuan Jade Cave, Lingbo, and so on.
Besides, NPCs in the game are not easily swayed by players who know the original story.
Take a simple example, like the quatrain just recited by Sanyue. If she had recited it in front of Duan Yanqing the first time they met, he surely wouldn't have given her a second glance, only giving her a look that said, "Are you sick in the head?", reflecting his contempt.
However, after Liuyun and Sanyue learned the secret past from Dao Baifeng's mouth, the System had already recognized them as privy to the matter.
Only now that she recited these four lines could they truly unleash their horrifying power!
