There's no way to use the timeline, I'm not Chendong, and I don't know how to determine his vague timeline, so I can only speculate and guess. Except for the known Hengyu, Void, Western Emperor, Beginningless, Blue Emperor, Ruthless, Feather, and Nine Holy Bodies, the rest of the time cannot be determined. And even if it is known, the timelines of the Western Emperor and Hengyu overlapped, the Western Emperor Mother suppressed the turmoil in the Taichu Ancient Mine, 190,000 years ago, and Hengyu also visited the Taichu Ancient Mine 180,000 years ago. The key is this preceding word, the Queen Mother of the West must have become an emperor 200,000 years ago, and Hengyu could only go to the Taichu Ancient Mine 180,000 years ago at the earliest, that is, just after becoming an emperor. However, Yuhua died 300,000 years ago, even if it was exactly 300,000 years ago, the ruthless man was more than 200,000 years ago, because he had four emperor bodies, the earliest one was the Swallowing Heaven Emperor or 280,000 years ago, the second life followed, that is, 240,000 years ago, the third life went to the ancient abyss, and then the Western Emperor became enlightened, and then Hengyu, then the Nine Holy Bodies, after the Void, and then the Chaogu, and then the Nanling Heavenly Emperor The fourth body of the ruthless man, and then there was no beginning. During this period, it is impossible to stop the emperor, so the emperor can only be arranged before the Feather God Dynasty, and the Jiuli Emperor is the same as the emperor. Then explain why the Feather Dynasty became the Zhongzhou Immortal Dynasty, after all, the Feather Emperor was there at the same time, and it was impossible for other dynasties to surpass it even if they had imperial soldiers, so during that period, Great Xia and Jiuli were overshadowed. This is a more reasonable timeline, and you have to find Chendong in the most formal.
