What props do you need for the million-year soul ring in Douro mainland?

The soul teacher is the most distinguished profession in Douro mainland. They can cultivate themselves into gods step by step, but each breakthrough stage needs the help of a soul ring. The life of the soul ring is also graded. As we all know, the soul ring of ten years is white, the soul ring of a hundred years is yellow, the soul ring of a thousand years is purple, the soul ring of ten thousand years is black, and the soul ring of a hundred thousand years is black, and a kind of gold is added every hundred thousand years. When it reaches the level of one million years, the soul ring will become gold. Soul rings come in all kinds of colors. Green and gold soul rings are considered to be something that Tang San has never seen before. When Tang Wulin became the soul king, he got a green and golden soul ring because he inherited the blood of Lan Yindi and integrated the energy of the golden tree. Gold is generally a million-year level, and the green gold soul ring doesn't know the age at all, nor does it give Tang Wulin soul skills. It is better to give it a ten-year soul ring.
