The fact that Yun Qianyu could save Hua Mei and kill two powerful spirit energy users was all because of Xiao Jiuyuan. If she had to face Luo Nantian alone, she probably wouldn't have survived.

However, if she had to face a cyan level spirit energy user head-on, she wouldn't stand a chance against him.
