Zhou Zhou's second ranking battle was against the Lord of the Holy Unicorn Race from the Heaven Realm.
According to the Index of All Races (Book Seven), the Holy Unicorn Race was one of the symbols of the Heavenly Realm and one of the favorite creatures of the Gods of Order in the Heaven Realm.
They were a race with Extraordinary-Tier bloodlines!
As long as the Holy Unicorn reached adulthood, it would naturally advance to Diamond-Tier.
It would easily advance to the Extraordinary-Tier with a little hard work!
A Holy Unicorn with outstanding potential could easily advance to the Epic-Tier or even Legendary-Tier with hard cultivation!
Moreover, it was different from the meager White Silver Behemoths.
The reproduction ability of the Holy Unicorn was not inferior to most races, so they were populous.
Therefore, the legend of the Holy Unicorn could be easily heard in the myriad worlds.
