In the first Ancient Ruins Space, Zhou Tian had several life-threatening encounters. In the second Ancient Ruins Space, not only Zhou Tian faced life-threatening danger, but also ended up making a profoundly strong enemy. If it weren't for the unplanned intervention of those NPCs, Zhou Tian might soon have had to deal with their threat.
And in the third Ancient Ruins Space, even though Zhou Tian gained more benefits, the enemies he made there were likewise more powerful.
Regardless whether Zhou Tian enters the Ancient Ruins Space again, he cannot guarantee his gains, nor does he believe he can take advantage of his position. Truthfully, past experiences have made Zhou Tian wary of potential threats from hostile forces lurking nearby. If anything goes wrong, he could be killed by his enemies at any moment.
In a situation like this, while he still hasn't resolved the previous trouble he encountered, if he were to provoke more enemies, no one would be able to save him then.
