When Ethan asked Shadow Kane to receive his full-powered attack, he was not expecting the assassin to really agree to his words.
He thought he would need more time to try convincing him.
However, to his surprise, Shadow Kane directly agreed to his words, making Ethan guess the other party had some other intentions.
Nevertheless, Ethan was still happy because he also had his own intentions that would help him kill the Gold Ranked Assassin in front of him.
'Unlike the time when I killed the Demonic Blood Bat King using the similar strategy, I can't upgrade my Cultivation Techniques as they have already reached the maximum mastery.'
After upgrading his Cultivation Techniques to the Perfection Stage, Ethan wanted to at least know the cost of the next stage; however, there was no response from the system.
Hence, Ethan concluded that the Perfection Stage is the highest mastery stage one could achieve in his cultivation techniques.
