When Jiang Tang opened the doors to the Southern Sea Dragon King Palace, a powerful burst of rainbow light and Spiritual Energy suddenly erupted from within.
He took it all in, of course, utilizing his own space to collect and store this rainbow-hued Immortal Qi.
Despite his absorbing method, a bit of the luster still floated up to the ocean's surface and dispersed into the air, sending a rainbow sheen soaring into the sky.
Jiang Tang deployed the technique for unlocking the palace doors, a sealing function similar to that of the East Sea Dragon King's, also the work of Buddhist People, though with slight variations. But small as they were, he was able to handle these minor issues.
The East Sea Dragon King, watching nearby, couldn't help but admire him. He himself had struggled for so long, almost to the point of exasperation, and had still failed to open the palace doors.
He had even secretly learned some Buddhist Law for unlocking, to no avail.
