This is not only because that cultivator is too powerful, but also because the Qi of Heaven and Earth is limited, and the stronger the cultivator, the more Qi gathers around them.
When the Qi is concentrated on one person, others will have little chance to rise.
Just like in a river, there can only be one dragon, while others are mere small fish.
The Qi of Sword Dao is not as small as a river; it's more like an ocean.
But likewise, there are too many small fish in the Sword Dao sharing the Qi.
From this perspective, the reason why there are only three Sword Immortals in the Chang'an Years, apart from the difficulty of becoming a Sword Immortal, is also because this ocean of Sword Dao can only accommodate three Azure Dragons!
After Li Qiubai opened Heaven's Gate and perished, it not only expanded this sea of Sword Dao by countless miles, but also returned all the massive Sword Dao Qi he possessed back to the sea.
Out with the old, in with the new.
