Where did the Brahma Ruler Yao Lao gave him come from?

I know that Yao Lao took it from the Dou Di remains, but whose is it? Who created the Fan Jue? Who also created the ruler? Xiao Yan's ancestor. Didn't Xiao Xuan only have the Skyfire Three Mysterious Change? At that time, Xiao Xuan was already a 9 star Dou Sheng and was still using it. Why was it that Xiao Yan, who was a 6 star Dou Sheng, had almost completely ignored this skill? There was also Ancestor Huo Yun who had left behind a spiritual imprint when he possessed Xiao Yan's body. However, when Yao Lao possessed Xiao Yan's body, he did not leave behind a spiritual imprint. Why was this? Could it be because of Yao Lao? Then, shouldn't he at least tell her where he was? Did I miss it? It doesn't matter if I miss it. Let everyone help me answer my questions one by one, right? It's been bothering me for a long time. I can't read it again. After all, it's more than a thousand chapters... I remember that Xiao Yan had just said that he was a legend from Earth who came to the Dou Qi continent. I was puzzled. He said it like that and then did not mention it again.
The Drug Lord didn't say who made the ring for him.

Answer 1

According to the story of "Fight Through the Heavens", the Great Ruler of Brahma that Yao Lao had given Xiao Yan was a Divine Tool that Yun Fan had obtained on the Dou Qi continent. According to the novel, Yun Fan encountered many dangers and challenges while cultivating on the Dou Qi continent. In the end, he defeated many experts and obtained this divine weapon, the Great Ruler of Brahma Mantra. After Yao Lao learned of Yun Fan's situation, he gave the Fan Jue Ruler to Xiao Yan to help him train better. Hence, it could be inferred that the Great Ruler of Fan Jue that Yao Lao gave Xiao Yan came from Yun Fan, a treasure that Yun Fan had obtained during his training.
