The insides of the two old skins held some blackish bloodstains. They were obviously over a hundred years old, having suffered the erosion of countless ages. Of course, the exact lapse of time was something Xiao Chen couldn't precisely deduce.
As for the human skin inside the third ice coffin, the blood drops inside the coffin displayed a slight hint of vitality within the blackish red, indicating that no more than half a month could have passed. This was easy for a cultivator like Xiao Chen to discern.
This revelation made Xiao Chen instantly feel a chill, causing his hairs to stand on end. He carefully observed the inside of this skin and indeed, the bloodstains were also blackish red, with a hint of vitality. It seemed that not much time had passed since its removal.
From a meticulous observation, he clearly noticed that the third old skin was relatively softer, with an oily sheen. It seemed to have been shed not too long ago.
