A quest

( Lucifer's POV )

When Shakuni unleashed his true aura at the peak of tier8, Lucifer immediately dropped any and all ideas of fighting him. 

Rudra's unbelievable increase in strength was even more surprising to Lucifer than him not being dead, as last he remembered, Rudra was just half-way into tier7 when he fought Thor.

The EXP requirement to go from tier7 to tier8 was by no means small, however, the journey from tier8 to the peak of tier8 was even more exaggerated. 

Even if Shakuni slaughtered entire planets a day, it wasn't possible to reach the peak of tier8 in just 3 years. 

Every other monarch that he knew of in the universe had spent centuries moving from tier7 to tier8 and even till date, except that wicked master of his who was older than time, Lucifer had not seen a single individual who had reached the peak of tier8, including his brother Micheal.
