The Demon Race is an extremely formidable opponent, even though the human race emerged victorious in the War of Deification, they never underestimate the Demon Race as weak.
An enemy is only worthy of being called such if they're evenly matched. If you describe your defeated enemy as weak and insignificant, then where lies the glory of your victory?
On the contrary, as the victor, the stronger and more resilient your enemy, the more precious your victory becomes, highlighting your glory and strength.
The Demon Race, having battled the human race for countless years, is the greatest opponent encountered during the human race's rise, far surpassing all opponents met during the exploration of the Realms of Heavenly Seas.
Even during the phase where many human elite pioneers of the Divine Land World faced resistance, some worlds exhibited power no less formidable than the former Demon Race, perhaps even stronger.
