Joshua was once an ordinary Silver knight.
He had neither special bloodline nor powerful innate talent, and was just an ordinary vanguard commander, leading his troops to kill on the battlefield.
That did not change after the melding of souls and coming to own the System. Even if Joshua did possess martial art techniques from the pre-existence and could rely on the System to raise his own ability, he remained a mortal without powerful bloodline or innate talent.
In other words, a human that could not be more normal.
But everything changed once he acquired the Azurite, the legacy of the Chaos Guardian.
[Power of the Guardian's Legacy: All attributes gain permanent +20, all attributes gain permanent +0.01 for every Chaos monster slain (Bloodline Legacy can be selected after death, the margins of the Legacy would be decided according to individual's essence)]
[—The legacy of eras continues, never to end.]
