Prehistoric: the Lich War and the Whole Clan's Destruction

Emperor Jun's Sun Star transformed into the Great Luo Jinxian, and encountered an extraterrestrial demon who was crushed by a prehistoric barrier. After reading the other party's memory, he froze - there was also an emperor in that world, who established the Demon Court, became the Demon King, and enjoyed unlimited glory. In the end, the Lich War destroyed the whole family, and his younger brother Taiyi did not survive. The flames under the Fuso Sacred Tree were still burning, and Di Jun clenched his fists: I will no longer be the Demon King.
