Chapter 79: Carbon Filter
"It’s a mixture of mercury and sulfur. My guess is that the ancient river became the deep ravine it is today because of a volcanic eruption a long time ago. There are also clues that there are alkaline hot springs underground. This is the source of the faint sulfur smell in the water. Beside that, there is a large amount of natural cinnabar too under the ground. The mercury pollution on the ground and water also comes from this natural cinnabar." Xu Xiang said while looking at the data on the screen of the poison detector.
A Lu Da looked at her and thought in his heart: ’It’s strange. I can understand her, but why can’t I understand what she is talking about?’
Seeing his puzzled face, Xu Xiang said, "Anyway, I can help you solve water problems and poisoning problems."
As soon as the words fell, A Lu Da’s eyes lit up. He smiled at her and said, "If you can really solve this matter for us, my Xiuluo tribe will be indebted to you. From now on, as long as you ask for help and we can help you, we will do our best to help."
Hearing his promise, Xu Xiang nodded in satisfaction, and then put the poison detector back in her space. A Lu Da looked at her with probing eyes when he saw the poison detector disappear from her hands. Thinking of the only time he saw the chief of the Mofa tribe use his ancestral treasure, his gaze lit up.
’Is she really a descendant of that chieftain of the Mofa tribe?’
Xu Xiang didn’t know that A Lu Da had already regarded her as a descendant of the Mofa tribe. She thought for a while and said, "Let’s make an activated carbon filter first."
"Carbon filter? What is that?" He asked curiously.
Xu Xiang smiled mysteriously at him and said, "If you want to know, let’s go to the open field first."
