Legend had it that just after stepping into the Legendary-realm, Cardson even went to the Eternal Iceland alone for as long as a year, all for the sake of tasting the meat of the Iceberg Snow Demon. Just as everyone else thought he would never make it out alive, he came out heavily wounded with a Legendary-level Snow Demon King on his shoulder.
Legendary-level magical beasts were originally more powerful than Legendary-level humans. Besides, the harsh environment in the Eternal Iceland had a huge impact on humans, but it was a natural habitat for a magical beast like the Snow Demon. Under such circumstances, he even managed to kill the Snow Demon King, which was something that many Legendary powerhouses of his generation were amazed by.
