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."

After finishing speaking, she walked towards the place where A Lu Ge took her to have dinner last night. A Lu Da looked at her back in puzzlement for a while, before following her. When they came to the open field in the center of the camp, the people of the Xiuluo tribe were preparing lunch.

Seeing her coming, they stopped what they were doing and stared at her. Ignoring their gazes, Xu Xiang pointed to the bonfire and said to A Lu Da, "Bring me as much charcoal as you can. I need them to make carbon filters."

"All right." A Lu Da replied, and went to pick up charcoal from the bonfire.

While A Lu Da was busy taking charcoal, Xu Xiang looked around, and then walked towards a large wooden barrel. Looking at the empty wooden barrel, she thought for a while and dragged the big wooden barrel away. When she came to a place not far from the bonfire, Xu Xiang wiped her sweat and waited for A Lu Da to bring her the charcoal.

She waited for a few minutes before A Lu Da returned with a pile of hot charcoal. Looking at the amount of charcoal, and then looking at the big wooden barrel, she said, "The charcoal is not enough for this big wooden barrel."

’Should I use those charcoal in my space?’

While she was still thinking, A Lu Da said, "We can go to the warehouse to get some more charcoal."

When Xu Xiang heard that they had a warehouse, she looked up at him.

"How much charcoal do you have?" She asked calmly.

"It should be a lot. Those charcoal are prepared for winter, and we have started stockpiling them this spring." He answered her while thinking.

Xu Xiang nodded and said, "Then let’s get the charcoal. Before we can use them, we still need to grind them."

Pointing to the big wooden barrel that was almost as tall as herself, she said, "Take this wooden barrel with you. Please, lead the way."

A Lu Da looked at the big wooden barrel and asked curiously, "Where did you get this wooden barrel?"

Xu Xiang pointed to the place where she got the wooden barrel and said, "There."

He looked in the direction she pointed and fell silent. Without saying a word, he lifted the wooden barrel and carried it behind his back.

"Follow me." He said as he walked towards the warehouse.

Seeing that he was carrying the heavy wooden barrel with ease, Xu Xiang gave him a surprised look, and then followed him closely. The two walked to the desolate area of ​​the camp and stopped in front of a large underground cellar.

A Lu Da put down the heavy wooden barrel and said, "This is the place where we store our food and charcoal. You wait here, and I’ll get the charcoal."

She looked at the doorway of the underground cellar and said, "All right."

As A Lu Da took out the pile of charcoal from the underground cellar, Xu Xiang went to find the fine sand needed to make the carbon filter. She looked around the camp for a while before finding the fine sand suitable for an activated carbon filter not far from the camp. Just as she was still thinking about how to bring the sand back, she heard A Lu Da’s voice coming from her back.

"What are you doing there?" He asked, while approaching her.

Xu Xiang pointed to the sand and said, "We have to take this sand back. I’ll leave it to you."

Leaving this sentence behind, she walked back to the camp. A Lu Da looked at the sand and sighed. He scratched his head and thought: ’Did I find myself a coolie job?’

Xu Xiang looked at the pile of charcoal piled up next to the big wooden barrel, and took out a big mortar and pestle from the space. Putting the charcoal into the mortal body, she began beating the charcoal with the pestle. After a few minutes, the charcoal has turned into powder.

She looked at the big wooden barrel and thought: ’Looks like I need to prepare more charcoal powder.’
