Xue Ying was clear that with his attainments in the Dao of Mirage and the 'Vermillion Nightmare inheritance' which a senior had created, only then could he reach the Vermillion Nightmare sixth transformation so easily. Even though he spent over five million years pushing another cultivation system all the way to the 'fifth level Star Pagoda strength', this short period was not worth mentioning against the eternal life of cultivators.
'It'll be very hard for me to improve further.' Xue Ying thought.
He was at a huge bottleneck–from the Unity realm to the Primal Chaos realm. Even the Voidwalker system or the 'Dao of Mirage' which he had the greatest hope of breaking through would require him to cultivate for a very long period, much less the Vermillion Nightmare inheritance.
