Song Shuhang had confirmed from the very beginning that this Cheng Lin, originally golden and now of a glass gemstone color, was not the "Cheng Goudan" he had been in contact with.
He was clear on this point.
However, from many characteristics, although the glass gemstone-colored Cheng Lin was not the "Cheng Goudan" Song Shuhang knew, she might indeed be the real Cheng Lin.
This point is actually not hard to understand—because as a fragment of "Ghost God Cheng Lin," Cheng Goudan can fuse with other fragments.
Father Goudan had also assigned Song Shuhang a long-term task of 'collecting Cheng Lin's fragments.'
Unfortunately, Song Shuhang cultivated until he reached the Immortal Realm and hadn't encountered any other fragments of Cheng Lin.
And now, the true identity of this glass gemstone-colored Cheng Lin, if not mistaken, should be Song Shuhang.
