As the only king of the White Shell Royal City, the White Armor Emperor naturally knew the danger of the Demon Subduing Tower, but this danger had been dormant for too long.
It had existed since he discovered this place, but it never erupted.
Furthermore, the White Armor Emperor even once felt that the danger under the Demon Subduing Tower might no longer be a threat. It wasn't until the moment the White Armor Emperor became a king that he once wanted to enter the Demon Subduing Tower to find the opportunity at the bottom of the tower.
However, at that time, he sensed the presence of a king, which seriously threatened him.
At that time, the White Armor Emperor was only a junior king.
He even thought that if a king had been hibernating in the Demon Subduing Tower for tens of thousands of years, his strength couldn't be underestimated. Therefore, he only attacked tentatively once, but in the end, he didn't succeed.
