After a long time, Mo Zhitian finally walked out of this grass. In front of it was an open field, sparsely planted and seemingly uninhabited within a radius of several miles.

Mo Beitian took out the map again and checked it carefully, and after determining where he was at this time, he hesitated a little. According to the map marking, this should be the graphite mine in the upper reaches of the Blood River. But this is the largest graphite producer in Pallas, and such a place should be busy on weekdays. Even at night, there should be temporary settlements for workers all around, but it is a deserted wasteland, and it seems that no one has been here for a long time.

Mo Beitian was a little unwilling, and he enlarged the holographic map that the golden mask gave him according to the coordinates. Let it show the size of the scale 1:1000, and he can see the specific situation of the area. However, what is puzzling is that according to what is shown on the map, there is indeed a huge crystalline graphite mine here. And there is also a mining company next to this graphite mine.

God knows that in nature there is no pure graphite. They are often mixed with other substances, usually in the form of quartz or pyrite. Due to the different ways of existence, the form of their crystallization is also different, and their use in industry is also different. At present, there are about three kinds of crystalline graphite that can be mined in the territory of the Republic: one is dense crystalline ore, which has a high graphite content, but has poor plasticity and is not of great industrial use; The second is squamous graphite, which is not as dense and crystalline as the content of graphite ore, but it has excellent plasticity and lubricity, and its use is also the most extensive; The third is cryptocrystalline graphite, which is the best quality, but unfortunately it is extremely difficult to mine and purify. As early as 200 years ago, some people in the old era were trying to reduce the difficulty of purifying this kind of graphite, but until now they have not found a very good solution.

This large graphite mine in the upper reaches of the Blood River contains the second crystalline ore, which also contains a smaller third type of graphite ore. Such a marketable mineral deposit is actually a wasteland? But is there something wrong with what is shown on the map? Mo Bitian thought about turning off the image data in the hologram temporarily, and then returned to the settings to find the map information time, and he found that all the map data provided by this map was from last year, which means that there should have been a mine and a mining company here last year, but Mo Bitian felt that this place seemed to have been abandoned for at least a few decades.

The more I thought about it, the more I felt that something was wrong. What did Paul do here? Since the clue suggests graphite, where is the graphite? And when I was in Pallas, I knew that there was a graphite mine here in the Blood River, but how did this mine disappear in a blink of an eye? And it looks like it's been missing for years.

No, there must be something missing in this. Mo Beitian thought about it and took out the button again, he carefully put the button on the palm of his hand and looked at it for a while, but there was still no special clue. He was afraid that it would be dark and he could not see clearly, so he pointed the button at the moon again, wanting to take a closer look through the bright moonlight. Sure enough, when the moonlight shone on the buttons, a faint line of text appeared on it, which read: "InitialLaboratory", which is the English word for "Initial Laboratory". Mo Zhitian put down the hand holding the button, and the line gradually disappeared.

The first lab? What does that mean? What does this lab do? Graphite-related? Mo was stumped by the emerging problem again. There was writing on the button, and it turned out that he didn't notice it because it was daytime. It seems that this text can only appear at night with the help of moonlight, and it seems that someone does not want others to discover this secret easily. But when you think about it, this is not a clever move, if the condition for seeing this text is only moonlight, then it is too easy to see through, right? The answer to this question is probably not that simple, there must be something I haven't noticed. Maybe the moonlight is just one of the conditions, and there is something else here that is the condition that makes the button manifest the text. Wait, since Paul hinted at allowing himself to come to this place, what is unusual about this place is the environment? What is the context of the text that contributes to the manifestation of the text? This thought flashed through Mo Beitian's mind, and he suddenly felt that this was the most reasonable explanation.

Mo Yitian has always thought of what to do, and he quickly looked around, trying to find the basis for his thoughts. Sure enough, he noticed a faint yellow glow from a rock not far away, and Mo Beitian could tell at a glance that the light was not natural light but the light emitted by the lamp. He tried to point the button in his hand towards the light source, and the words appeared again. He placed his other hand in front of the button to shield the light source, and the line quickly disappeared again. He took his hand away, and then pointed the button at the moonlight again, and slowly reappeared. Mo Bitian tried to hold the button with one hand and put the other hand on the button to block the moonlight, and the words disappeared with the moonlight. After trying to shiyan back and forth a few more times, Mo Yitian was finally able to come to a conclusion: the appearance of the words was the result of the combined effect of the moonlight and the light on the other side of the stone.

Suddenly, it occurred to him that since this place had been abandoned for a long time and was uninhabited for several miles, how did this light come about? Could it be that someone is hiding here? Thinking of this, Mo Yantian took out the folding saber from the bag behind him, and carefully slid it to the edge of the rock step by step.

Mo Beitian stood still with his back against the rock, his right hand clenching the saber, and his head slowly poked out to look behind the rock. There was no one behind the stone, and the light came from the bottom of the stone.

Mo put away his saber and tried to push the rock with both hands, but the boulder more than one person high was actually moved a crack under this push. It's not rock at all! Mo Yitian touched it carefully with his hand, yes, this is indeed not a rock but a synthetic material. On the surface, the texture is similar to that of stone, but it is much less dense than stone, so it is very light. Mo Yitian felt that the effect of putting it here was obvious, it was a disguise. The person who placed it didn't want others to find out about it, and this unspeakable thing must have something to do with the light. Thinking of this, Mo Zhitian pushed this "stone" again, and this time, the "stone" was completely removed. Underneath the "stone" is a deep cavern from which the light emanates. There is an iron escalator on the side of the deep cave, which seems to be easy for people to go up and down.

Mo Yantian glanced down, and pondered for a while, if you want to find the graphite mine, it is likely to be down here, since it must be hidden by someone, there must be some reason, it seems that only by climbing down to see what is going on can this secret be solved.
