Indeed.
Since this Martial Emperor's secret treasure might have other entrances, these entrances would definitely be found by other people too.
Once they were found, the news would surely spread out.
At that time, other sects that were near the entrances would definitely send in their young disciples below forty years of age here to search for treasures in the Martial Emperor's secret treasure as well.
Even a second-rate force would be tempted by the treasures inside the Martial Emperor's secret treasures. The second-rate force was ranked higher than their third-rate force. Moreover, they also had a Martial Emperor guarding their force.
These kinds of sects would have no shortage of young disciples that possessed insane innate ability and bizarre comprehension level. Apart from that, these young disciples would certainly possess an overall strength that was greater than theirs.
After all, they were only the disciples of third-rate forces.
