The Taichu Sect's immortal light signified the original intent of the world. If one cultivated it to the extreme, one could kill an Immortal Ascension stage cultivator with a wisp of dense immortal light.
Although there was still a prefix of "certain probability" to kill an Immortal Ascension stage cultivator from a practical point of view, only a few divine powers in the Sea of Realms could achieve it.
At the very least, Fang Jinyu couldn't do it even with his divine power in the heavenly book.
Even the attacking divine power in the heavenly book, the heavenly laws, could only suppress one person of the same stage after being cultivated to the extreme. However, it couldn't go further.
