In the past 20 days, Retdoz hadn't met with Su Yu, they only occasionally chatted online.
Now upon meeting, he immediately noticed Su Yu's enormous transformation!
This change was mainly reflected in his strength.
In just 20 days, Su Yu's strength had actually stabilized, and he was already a standard Planet-Class First Rank cultivator!
20 days ago, Su Yu's realm was yet to stabilize.
Retdoz had met him and at that time, Su Yu showed signs of just having broken through to the planet level, far from realm stabilization. Little did he know that in just 20 days his realm had stabilized!
Don't think that "realm stabilization" is an easy thing, when Retdoz had first advanced to the planet level, it had taken him a whole two years to stabilize his realm.
And Su Yu, 20 days! How could this not amaze him?
