The liaison officer scanned everyone before saying, "None of the previous players who went in have come out alive."
This isn't a timed instance, so it's not unusual for players to be stuck inside for a while. Since there's no way to contact the outside world, all information about the instance comes from devices and whatever the Purple Life Research Institute left on record.
The research institute is where the instance originated, but Xu Huo noticed the available info on the institute was quite vague—probably nothing crucial was left behind, so it wasn't very valuable. The reason they suspect this is a multi-space instance is because devices detected clear, abnormal fluctuations of spatial power.
Instances involving space-time or mental elements are always more difficult than ordinary instances. Sometimes you can't break through just with combat ability—you need luck as well.
