Hong Dali used the lighting equipment and curiously shone on those giant old trees from afar, approaching it slowly.
Soon, he got nearer. When Hong Dali got closer and used the lights to shine beyond those weird old trees, the Bureau Chief was shocked. He stared at the computer screen and mumbled to himself. "Oh my god… The giant numbers here are… they are actually… wood fossils!"
Tang Muxin asked softly, "Wood fossils, what is that?"
Lin Chuyin explained. "Wood fossils are trees that have been buried underground for millions of years or earlier. The chemical substance around the trunk, such as silica, iron sulfide, calcium carbonate, etc., seep into the interior of the trees through the groundwater, replacing the original composition of the wood. The shape of the trees remains, but fossilization occurs due to the petrochemical effect. Due to the high content of silica, the fossilized trees are known as petrified wood. Also called jade trees."
