The Iron Crown Immortal stroked his beard with satisfaction, "This is the Sect Leader's Identity Token. With it, you may freely enter the Scripture Pavilion, peruse the books of our forefathers, including some phrases about the Immortal Realm."
Zhou Yi, perplexed, asked, "Many of our forefathers have ascended, and we have connections to the Immortal Realm, so why is the information so scarce?"
"The barrier between mortals and immortals is not as simple as you might think, and even immortals cannot bear its immense consumption."
