After Qin Wentian condensed his 2nd Astral Soul, the Dreamcast Astral Soul, he had once again used his acupuncture needle techniques to camouflage the radiance of his Astral Soul. However, this time around, he didn't suppress the radiance too much, only lessening the intensity of the gold corona's radiance.
Qin Wentian had thought of this beforehand. Based on the authority Ye Clan wielded in the Royal Capital, if he don't display sufficient talent to attract the attention of the Emperor Star Academy's elders, it would be extremely difficult for him to stand alone against the entire Royal Capital. He didn't dare to release the intense pure-golden radiance of an Astral Soul condensed from the 5th Heavenly Layer, because if his talent were shown to be too monstrous, his opponents would try to kill him regardless of any cost.
Hence, his concern led to the current situation.
