Hao Ren and the others had arrived just in time as the problem regarding the "First Born's remnant" in Helcrown's energy core only arose an hour ago. However, in the eyes of those in charge of the power reactor, the situation was not as serious: it was just releasing some seemingly harmless, low intensity signals. Plus, these signals had not caused any fluctuations of magic power within a hundred-mile radius. Therefore, the technicians only reported the situation to the technical supervisor, but did not issue a high-level alert.
If it Hao Ren and the others had not spotted the illusion of Helcrown above the atmosphere when they arrived, no one would have thought that the city was having a situation. On top of that, the illusion would not have been associated with that particular energy core.
