There were many entrances to the Killing Tribulation Planet where one could choose to enter.
Qin Chen and the others simply chose one of such entrances and went in.
The killing tribulation one would encounter would naturally be different when one entered from different places.
If one specifically chose the entrance with greater and more killing tribulations, it could possibly lead to the outcome of one being blasted into pieces the moment one stepped in. This was a conclusion that some people had come to, which was why they guessed that the killing tribulations could kill Great God-realm experts.
Qin Chen and the others had chosen a place where the killing tribulations were very weak. Before them, experts from powerful cosmic races had also entered via this entrance.
The power of the killing tribulation wasn't strong, so Whitey was able to withstand it alone. It didn't cause too much damage to its body.
