Feng Jun left the forbidden territory so easily? Anyone who thinks that is seriously mistaken.
In the more than an hour he stayed, he discussed with the Big Boss whether they could use visual deception to fool the Nascent Soul Tree Demons in the forbidden territory, creating the illusion of leaving, but in reality... leaving very slowly.
Such a method of weakening one's presence was once used by Yi Jue, the True Immortal, with great effect. However, that was to blend into a crowd like a small transparent figure, whereas now he wanted to weaken his presence in the wilderness, especially with two True Immortals present.
True Immortals are certainly harder to deceive than Golden Core Masters, which makes him a bit worried whether the Big Boss can pull it off—the five-thousand-mile isolation zone outside this forbidden area is really too wide, he doesn't dare to recklessly leave traces nor wants to enter through the void.
