All along, Su Yu had believed that the person with the bloodline symbol was the traitor. When he first reached that conclusion, he was still a weakling. He had only discovered the bloodline symbol through pure coincidence.0

It was an insignificant scene he had seen from the Divine Skywing Sect master's blood essence. He only learned about the origin of that symbol much later after going through various hoops.1

He had asked the old turtle, He Tu, and Xia Chen about the symbol. These were essentially old fossils or the dead. In truth, very few people of the current era still knew what bloodline symbols were. Thus, Su Yu was finding it hard to believe that he had been fooled by the traitor long ago.0

This wasn't a knowledge he had gained abruptly through sheer luck. Instead, it was something he had learned bit by bit, starting from when he was still a weak Mental Tempering cultivator, until the point where he grew enough to get in contact with ancient experts like the female furball.0

He wouldn't have been able to ascertain that Silk Destroying King was the traitor...0
