Sword Bites the Eight Wastelands

The more I look at the distribution of strength, the more confused I become. Doesn't it mean that Xuanhong Sect is one of the eight major sects in Tianyuan Continent? Chapter 98 of the First Level of the Sect Master's Gold Level also mentions that he is the backbone of the sect? There is an ancestral spirit in the sect who was once an immortal, right? It's an N-level difference. A young prince's bodyguard is already at level 2 gold level! Since it is said to be one of the eight major sects, it represents the entire continent, right? Although there is hidden strength, it is not that different. Didn't the protagonist easily destroy the eight major sects before he was reborn? Or should I say that there are many continents. If you write it like this in the front, it will be difficult to pick up later. I think the strength setting is too unreasonable.
