In the long memories of the Fourth Dark Heavenly Dao, more than a thousand years ago during the battle for the "Ninth Heavenly Dao," there was indeed a guy named Tyrannical Song who stood out and truly possessed the qualifications for "Immortality."
If it weren't for the interference from the remains of the undying shell of the Eighth Heavenly Dao and it, it's possible that this guy called 'Tyrannical Song' might have actually proven himself as the Ninth Heavenly Dao.
However, with its covert interference, exerting force from behind the scenes, the position for the Ninth Heavenly Dao remains vacant to this day, with no one successfully proving their Dao.
Now, this Tyrannical Song is merely a top-notch 'Immortal.'
Even after a thousand years, at most, the other party has reached the level of that man from Confucianism back then, suppressing the world, invincible under the heavens... but as for matters above the heavens, the other party should have no capacity to interfere.
