Being in that environment at that time, Zhou Tian's options were quite limited. Either way, at that time, Zhou Tian could only choose to give up. If he wanted to retreat now, he could do so easily, given the power of the Abyss World, before the Space God King returned.
However, if Zhou Tian truly decided to do that, it would mean he was abandoning the idea of rescuing his true form. Because after the current events unfolded, Zhou Tian knew that the Space God King would certainly be more focused on the sealing of Zhou Tian's true form. And given the Space God King's strength, if he truly locked onto that seal, theoretically, rescuing his true form would be a task a hundred times more difficult than now.
It could even be said that with adequate preparation to prevent Zhou Tian from moving it away again, rescuing his true form would be almost impossible.
