During Su Mo's interactions with the Fertile Soil Era God of the Ocean, his acquisition of this card did not attract the game's attention in the slightest.
The main reason for that was not because the game was unable to detect it.
Instead, it was because the game had never seen something like that appear in the wasteland.
The rules did not impose any restrictions on experience cards, nor were there any corresponding contingencies for such things.
This meant that even if the game detected the new card, it would still be treated as an ordinary card.
In a way, this card was also not something that the God of the Ocean had left as a reward.
It was a tool that had been formed by the Fertile Soil Era God of the Ocean through extracting a portion of the energy within his body, according to Su Mo's request.
