The Yin Sect was something that Jiang Feng had only gotten to know about the past few days.
He had little information on the Yin Sect.
He only knew that they were powerful, but he did not know just how powerful they were exactly.
The only reason that he had Qingqiu joined the Yin Sect was not because he wanted to let Qingqiu work for them, but he wanted Qingqiu to see what they were all about.
Since he had offended the Yin Sect because of Xuanyuan Li, the Yin Sect would no doubt find him about it afterward.
Only by knowing himself and his enemies could he prepare his plans against them.
If the Yin Sect were not as powerful as he thought and had offended him, then he would find a chance to simply eradicate them.
