When Simon killed the Demon King of Death, he knew that he could not leave the demon king's corpse in the demon realm.
A demon king was comparable to a demi-god, and the corpse of a demi-god was extremely valuable.
Even for Simon back then, he was planning on using the corpse to craft a treasure or something that would be immensely helpful to him.
'I remember that after I killed the bastard, numerous gods sent me messages to sell the corpse to them.'
'Even the system back then told me that I'd receive a surprise reward if I gave it to the system.'
'I rejected all their offers and decided to keep the corpse in a safe place in my kingdom.'
'I did not even tell any of my friends or even my wife where the corpse was stored because I foolishly believed that I was protecting them.'
'Me refusing the offers of the gods and even the system placed me at odds with many gods and even a few Heralds.'
'I believed that if they didn't know, then the gods couldn't attack them.'
