"Earth Immortal Tomb?"
"Can this statement be trusted?"
Tang Yue heard this and felt delighted.
Despite being suppressed for over two hundred years, Zheng Jiuling's insight surpassed everyone else's. Otherwise, he wouldn't have gained such a huge reputation. As soon as he emerged from the Valley of Life and Death, people invited him to explore tombs together.
"That's right!" Zheng Jiuling nodded slightly, pointing at the tombstone, "This tombstone is made of a material called Black Nether Stone. Although not well-known, it's an extremely hard stone, usually found at the sea bottom of Star Gathering Scattered Island!"
Through Zheng Jiuling's explanation.
Everyone finally understood the reason.
It turned out that this stone is extremely difficult to mine and highly valuable. Generally, Human Immortals can't afford to use it. Most of it is used by Earth Immortals, but even ordinary Earth Immortals only have a small amount, mostly used for constructing the main burial chamber.
