"Immortal veins are like spirit veins. They're formed by the condensation of immortal Qi underground."
"Ordinary immortal meridians will give birth to immortal Jade, and some immortal meridians will even give birth to immortal spirits ..."
Tang Hao knew about immortal veins.
He had caught a Celestial Spirit on planet Dong Ling, and celestial Jade used to be the currency in the heaven-equal yard.
As for immortal crystals, they were different things. They were of a higher grade than immortal Jade, but not as good as immortal spirits. They were the purest crystals of immortal Qi and were very rare.
According to Tang Hao's estimation, immortal crystals were quite precious on Pangu continent.
