The introduction above is also quite vague: "This item was found from the Earth's Core six hundred years ago, and it seems to be the legendary 'Mao Day Gold Essence'. It is resistant to the fiercest of fires, sometimes as heavy as a mountain, at other times as light as a feather, possessing an Innate self-healing ability..."
"Could this thing actually be the Mao Day Gold Essence?!" Zhao Sheng touched his chin with his right hand, his mind deep in thought.
Gold is the most common in the Cultivation World. From a hundred jin of gold, one can refine a small amount of Golden Essence, which is a superior treasure material for refining Magical Treasures.
And Golden Essence can be further refined to produce Innate Gold Essence.
If Innate Gold Essence could drift and float in the Great Sun for hundreds of millions of years, absorbing the essence of the Great Sun and giving birth to spirituality, it would become the legendary "Mao Day Gold Essence".
