This was also another main reason why Jiang Hui decided to target this white mystical turtle.
Otherwise, just for a single immortal elixir, it wouldn't have been worth his while to act personally, at the very least.
Immortal elixirs are indeed very precious, rare in this world, but to Jiang Hui, they had long been of no use, and for most of his core disciples, they were likewise of little effect.
Like Tu Wa Zi, Gu Chen, and those of half-demon descent, most had already reached the Realm of Quasi Immortal King.
Although that realm paled in comparison to a true Immortal King, it far exceeded a True Immortal. After reaching that realm, their life had evolved to such an extent that it's no exaggeration to say their flesh and blood could rival that of immortal elixirs.
The immortal plant the White Turtle carried on its back only held great allure to supreme beings who had not yet achieved immortality.
