Originally, Ethan thought that Elder Wren would help him leave the Greenfire Sect as long as he said it was for his breakthrough.
He had his reasons for his thoughts.
Unlike others, Elder Wren knew that he was an outsider who had only joined the Lin Family very recently.
So, when he heard Elder Wren agreed to send him out of the Sect, Ethan felt his plan worked and became happy until he heard Elder Wren's condition, which made Ethan frown.
The thing is, as soon as Theodore had woken up from his sleep due to the Blood Message Incident, the Lin Family had already sent messages to their youngsters in the Greenfire Sect about the Lin Family's crisis.
Theodore had already ordered them to stay in the sect until they broke through to the Golden Core Realm and all.
After that, many things happened as Ethan's preparations for the war boosted Theodore's confidence; however, Theodore had not told anyone about his preparations.
