Mang Qianjun joined the battle as people from the Peacekeeping Army came up, forming hand seals and releasing black Death Qi. This Death Qi enveloped the Peacekeeping Army, making it impossible for outsiders to see what was happening inside, but they could hear their agonized screams. By the time the Death Qi had dissipated, all that remained of the Peacekeeping Army were piles of bones.
Seeing the bones, Mang Qianjun nodded in satisfaction and said, "These bones are looking better and better!"
No sooner had he spoken than he heard the sound of a qin on the battlefield. Turning around, he saw Dugu Qianye playing rapidly on Xiaohuo's back, as many of the men in black died amidst the qin's music. When he recognized the qin in Dugu Qianye's hands, his eyes widened and he exclaimed in a low voice, "Fuxiqin! The Fuxiqin has actually appeared in this world!"
Mang Qianjun watched Dugu Qianye play the Fuxiqin, so astonished that he nearly forgot about the battle.
