Not to mention whether Zhou Tian will have the patience to once again cultivate a batch of angels to help invade the Paradise world, even if Zhou Tian does cultivate a new batch of angels, estimating by then to rely on their strength to take down the Paradise world may not be absolutely achievable.
Lastly, and most importantly, if things do evolve to that point, then instead of pondering how to deal with the Paradise world, Zhou Tian could actually consider invading other worlds. After all, although the outcome of invading the Paradise world is significant, compared to its difficulty, if Zhou Tian hadn't had a batch of angels, it might have been better to invade other worlds.
The main point is, even if Zhou Tian has angels, they may not necessarily be able to take down the Paradise world. If this action really fails, then basically there's no need for Zhou Tian to launch another action.
