It's just that...
Although Zhou Tian's series of attacks at the time paved a way to survival, the energy consumption for Zhou Tian was not insignificant. To take down those zombies, the amount of energy Zhou Tian spent back then could have been enough for him to live in the jungle for several years.
Even though Zhou Tian did not intend to get old and die in that jungle, it did not mean he was willing to deplete his limited energy so recklessly. After all, in such an unknown region, losing all his strength would, even temporarily, put him in a deeply unsettling situation.
Thus, after successfully breaking through those zombies, Zhou Tian didn't dare delay any further. Confirming that the zombies blocking his path had all been eliminated, Zhou Tian immediately fled toward the exit.
This time, no further accidents transpired. With the zombies blocking his way having been completely dealt with, there was no one left to hinder Zhou Tian as he escaped from the passage.
