The contaminants within the Experimental Building might not have been growing for a long time; if the living sample was placed in the laboratory prior to that, it might not withstand the contaminants themselves. Thus, the safety of the living sample must be considered before entering.
If one were to directly break through the wall, it would be necessary to reach the living sample ahead of the airborne contaminant dust. Of course, Xu Huo himself was now covered in contaminants and was effectively a "source of contamination," so directly touching the sample could also potentially contaminate it.
Glancing at the clock, Xu Huo melted the metal wall in front of him and instantly reached the location of the living sample within the laboratory. In front of him was a sealed black metal box, almost the height of an adult, with several ventilation holes at the one-third mark from the top—narrow and impossible to see through, yet admitting the low, non-human whimpering sounds.
