The Eternals' bodily structure was no different from that of humans. They had all evolved from ancient apes; they were merely a variety that the Celestials had meddled with during the course of evolution.
Though there were also individuals with unusual appearances due to mutations, none of the corpses here belonged to that type. They were all humanoid.
Given that their bodily structures were the same, their reactions to death should have been the same as well.
The contraction and dilation of human pupils was an important clinical standard for determining whether someone was dead.
Dilated pupils were one sign of brain death.
The principle was that pupil contraction was controlled by surrounding muscles. After brain death, the muscles relaxed due to the loss of neural signals, and the muscles controlling the expansion and contraction of the pupils worked the same way.
The corpse in Su Ming's hands had rotted beyond recognition and gave off the same smell as Wade, but when he pried open its eyelids, there were no pupils to be seen.
All of these people had died with their eyes rolled back. If one could see through them, their eyeballs would have been looking at the backs of their heads through their own brains, having rotated one hundred and eighty degrees.
As everyone knew, when subjected to extreme fright, the human nervous system went into shock to protect the brain. The specific symptoms were clenched teeth and rolled-back eyes, caused by the muscles receiving the final powerful bioelectric signal from the nerves.
Fainting prevented the brain from receiving further external stimulation. This phenomenon was also known as being scared unconscious.
These corpses were typical cases of people dying from excessive fright. If their internal organs had not already rotted away, Su Ming could even have pulled out
