Even if Zhou Tian had a good standing in the Main Plane, being in that world at that time, the Strength of the Main Plane was utterly unable to provide him any help. Given the circumstances then, Zhou Tian himself had calculated the difficulty of leaving that world and had almost given up on the idea of departure.
However...
Just when Zhou Tian had almost completely abandoned the idea of leaving, he had not expected the situation to take a surprising turn.
Zhou Tian recognized that he couldn't possibly learn from Pan Shi how to leave the current world, and with Pan Shi's obstruction, it was also difficult for Zhou Tian to defeat those powerful indigenous creatures. In such an environment at that time, Zhou Tian found it difficult even to protect himself, let alone think of a method to leave that world.
He had even prepared himself for the possibility of death.
