I have to swear an oath again? Hadn't I already performed the ritual to become a disciple earlier? Lu Yun secretly curled his lips, but he didn't object.
After all, he had already come this far, and taking another oath didn't seem like a big deal.
The Yuan Guang Immortal flicked his robe, and a magnificent light filled the gateway of the Supreme Dao Field as Dao Rhyme surged forth. In the void, it formed an oath in Daoist script—not long, but utterly solemn and grand.
"Swear with all your heart, then drip a drop of your essence blood onto the script," the Yuan Guang Immortal said.
Lu Yun solemnly recited the words, then squeezed out a drop of essence blood, which contained terrifying power, onto the Daoist script. It slowly vanished into the gateway.
Instantly, the gateway opened with a thunderous roar, and an ancient, heavy aura hit him full on.
"What's this all about?" Lu Yun asked, puzzled.
