Jiang Tang was attempting to approach the sun, and as he neared it, he felt an intense burning sensation enveloping his body. To overcome this difficulty, he used the Water Spell from his Spiritual Root, turning water into ice, and cast a ring of icy light around himself.
The ring of light reduced the scorching sensation on his body somewhat as he endured and entered the sun. It was only upon entering that he realized the sun, which looked like a giant sphere from the outside, was so vast within.
It was like The Mortal Realm's Earth, with a landscape of golden sand resembling a desert devoid of trees, only filled with sparkling golden sand.
He was curious about how Eryao managed to find Golden Crystals. Brushing aside layer upon layer of sand, he found the Golden Crystals he had seen before—actually chunks of gold-hued stone, glittering brightly.
