In terms of rarity and difficulty, the position of a permanent Domain King like him was above the difficulty of creating a Cosmic Supreme Metac. That is, a Domain with millions of Dao Lords could have ten Dao Lords with a Cosmic Dao, but only one Domain King.
So being a Domain King is a position that's one in ten billion Dao Lords and Dao Initiates. But upgrading a Minor Dao to a Major Dao is still rarer and harder to achieve.
Above that was upgrading a Major Dao into a Grand Dao. Then there was still the difficulty of upgrading a Grand Dao into a Cosmic Dao. So calling this goal a long shot would be an understatement.
The guardian was confident about their strength among their peers. But saying they could upgrade a Grand Dao into a Cosmic Dao pushed their confidence to the extreme. To be honest, they didn't believe they had that kind of talent.
