The Vermilion Bird Immortal Palace, how could Qin Wentian forget it?
His other true-self, Di Tian, had obtained the inheritance from the founding emperor of Grand Xia when in the Royal Tomb. The Xia Emperor passed him a key, and that key had always been in Di Tian’s possession since then.
How ancient was the founding emperor of Grand Xia, the Xia Emperor? Back then he barged into the immortal palace, one could only venture a guess as to how ancient that immortal palace already was back then. He still remembered that the Xia Emperor told Di Tian that the Great Dream Immortal Art, along with several other treasures, was obtained from that place. The Xia Emperor didn’t really venture into the core of that immortal palace, and his level of strength back then wasn’t sufficient to fully grasp the secrets of that place. He was only someone who took a risk, and that risk eventually allowed him to build an entire empire.
