Right now, in this forest area within the Ancient Ruins Space, except for the rather spacious passage, all other areas seem to be inhabited by the jungle creatures. When Zhou Tian previously ran into these creatures, he avoided them, not sense any large number of creatures in the jungle. However, now stepping into the living areas of these creatures, he immediately realized how dreadfully wrong his assumption had been.
Indeed, you can't comment before complete investigation; Zhou Tian truly did not expect that areas, in which he believed there weren't many jungle creatures before, turned out to be drastically different when he actually walked in.
In the end, Zhou Tian had only observed the situation from a distance before. In reality, as soon as he stepped into the living area of these jungle creatures, he immediately noticed something was off.
