The jade tortoise that Zhang Tie gifted them was the very target of the two girls since they attended Dragon Emperor Immortal Palace. It was an important item in Yin-Yang Sect.
Although it looked like a jade tortoise, actually, it contained the original version of a secret method which was of great significance to Yin-Yang Sect.
Was it a coincidence that Zhang Tie gifted it to them? Of course not. It could never be so accidental in this world. Now that it was not a coincidence, it could only be interpreted that Zhang Tie had already known that they were from Yin-Yang Sect.
The sudden pleasure and fear brought by the jade tortoise made Jiang Ruoxin and Ji Yuelan change their faces in a split second.
