The Last Piece of Immortal Energy

Yuan Qi travels across the world and suffers from one setback after another. Even so, he finds no traces of Yin. He encounters plenty of sycamore trees. But, they don't contain Feng Yin's last piece of immortal energy. Yuan Qi senses Yin's Soul Mark occasionally. It passes by and can't be traced. He always visits the Nether Realm during Yin's death anniversary every year. He leaves with disappointment after being mocked by Xiu Yan.
