"T-that's impossible! The peak of cultivation is the World Source Realm! If not, someone would have reach it after all this time!" Catherine said in disbelief, almost screaming as she spoke.
Ryker was not surprise. The only reason he did not react in such way was because he trusted his parents greatly, and he was just a beginner of cultivation during that time. So, he believe almost everything they said about cultivation.
Even when he reached the peak of the World Source Realm, he did not stop believing them, as he manage to fell something blocking his attempt to advance. He guessed other experts that reach the same height as he did also felt the same way.
"It is possible. Just that something blocking us from reaching that path." Ryker calmly answered.
If it was anyone else, Catherine would not believe them, thinking they were speaking nonsense. However, she knew Ryker would lie to him, not unless he was lied to in the first place.
