As the two belts of Heaven and Earth Spiritual Aura entered the Dragon's Edge, Chen Xiaobei could feel faint Spirituality swelling though the hand that grabbed the hilt.
'The Dragon Edge's Spirituality is almost the same as a Three-star Earth-God Instrument, which makes it almost the same level as the Heavenly Sword!" Chen Xiaobei noted with excitement.
Because the dragon swords did not have Spirituality, the Spiritual Aura they produced was substandard when compared to real Immortal Instruments.
Chen Xiaobei's initial expectation was to recover the Dragon's Edge's Spirituality to a Three-star Earth-God Instrument. He would have been very contented with that result. He did not expect his Dragon's Edge to reach three-stars so swiftly, not mentioning that it was still progressing!
That was way beyond his expectations.
