Given Zhou Tian's mediocrity and the fact that he only had one Epoch to prepare, depending on the Old Power System to attain Deification was extremely difficult and even impossible, no matter how one looked at it.
Despite knowing the difficulty of this task, and the impossibility of achieving growth under both power systems to the same extent under normal circumstances, Zhou Tian had no other choice. Even knowing his idea was hard to achieve, he could only proceed in that way.
Even a small hope was better than being controlled by others, for if Zhou Tian did not prepare now, resisting when the situation evolved to that point would become even harder. Thus, no matter how difficult it was to cultivate the Old Power System at this time, it was still something Zhou Tian had to do.
Even though Zhou Tian's talents made achievements in the Old System seem incredibly difficult or even impossible, if he really chose to do so, it wasn't without any hope at all.
