According to the plot of " The Second Season of the Nine Heavenly Songs ", the reason why Ge Nia did not defeat the Black and White Profound Jian head-on and retreated after rescuing Wei Zhuang was because: The Black and White Profound Jian was very powerful. As an experienced swordsman, Ge Nia knew that he was not strong enough. The relationship between Ge Nia and Wei Zhuang had become extremely tense. Ge Nia was worried that Wei Zhuang would use his sword to attack him, so he decided to leave first to avoid causing more trouble. 3 Ge Nia also realized that the Black and White Curved Sword might be tracking him, so he decided to leave quickly to avoid being discovered by the Black and White Curved Sword.
