Kapitel 670: Ch 670: Law Skill: Divine Sword Tribulation!

Inside the cave, Su Xue Er was holding Ye Xiao in her arms and had a worried expression on her face as she kept calling Ye Xiao's name, trying to wake him up. She also checked his body to see if he was injured or what was the reason behind him falling unconscious. She had noticed the black light shooting in the space between Ye Xiao's brows and knew that this might be the reason behind Ye Xiao's current condition.

She darted her gaze at the Blue Book on the ground. Right now, it has lost all of its lusters and seems to be just an ordinary book. 

When Ye Xiao opened the book, no words could be seen on its pages. Ye Xiao was able to see the words only through the Eyes of Insight, but now, she could see many words written in the book. There were also a few pictures of a person holding a sword and making a few moves.
