"A person?" Qiao Sang was taken aback, his face becoming serious as he couldn't help but hold the pet beast egg tighter.
Wild spectral-type pet beasts absorb negative energy, and someone deliberately not letting others out so that a spectral-type pet can absorb negative energy are completely different situations.
The latter is far more serious.
After a good while, Qiao Sang voiced his suspicion:
"Could this secret realm rift be man-made?"
Logically speaking, when so many secret realm rifts appear, a normal person's first reaction would either be to run away or to fight, rather than thinking about closing off the space to collect and absorb negative energy.
If the purpose of coming in was for a spectral-type pet to absorb negative energy, it would have started absorbing right upon entry, not waited until now.
This situation seems more like someone knew in advance that a secret realm rift would appear, hence the spatial closure and energy absorption were carried out.
