Kryptonians had appeared in the universe long before humanity was born, so it was only natural that their technological level surpassed Earth's.
But Rao had nothing to do with technology.
Many people could not understand why a highly advanced society like Krypton would have legends of gods.
In truth, the Kryptonian concept of gods was somewhat different from humanity's.
Humans believed that gods were gods and humans were humans—two entirely different species. Even if there were hybrids, they would only be demigods.
But the Kryptonian concept of gods was very vague. They believed that great people were gods. When someone was omnipotent or accomplished magnificent feats no one else could achieve, that person was a god.
That was part of the reason Batwoman and Superman had erupted into civil war back then.
Batman feared that Superman wanted to become a God Among Men, but Superman's definition of godhood differed from Batman's. He felt there was nothing wrong with becoming a god. The two talked past each other, creating even more misunderstandings and suspicions, until it finally escalated into the affectionate concern for the other's health: "Do you bleed?"
In the end, it was Martha who made Batwoman realize that Superman possessed humanity, causing her to abandon her targeting of him.
Back to the point—back to Rao.
Rao. In Su Ming's previous life, some domestic translations had rendered the name as Rui'ou or Ai'ou. They were merely differences in transliteration, nothing worth worrying about.
According to the latest Rebirth setting from before Su Ming transmigrated, the story went like this.
Rao had originally been an ordinary man on ancient Krypton. At the time, Kryptonians were still in the primitive stage of society, struggling even to eat and survive, living like cavemen.
You could not even call it a life of misery,
