Lin Gu did not stay long on the ground of the Lagu Snow Mountain. After walking alone in the Lagu Snow Mountain for about two hours, he went directly into a cave behind an inconspicuous boulder. Because although the students from the two battalions entered in batches and time periods, no one could guarantee that the two sides would collide directly. But after entering the cave, Lin Gu discovered an anomaly in the cave. The simple reason why he chose this cave as the entrance is because the entrance is not big and the location is obscure. Especially from the traces of the entrance, it is obvious that no one or beast has entered it for a long time. But after he entered the cave for about a thousand meters, he began to find more and more traces of people's activities, and these traces all looked very fresh. The underground of Lagu Snow Mountain is actually, to put it bluntly, simple and simple, but complex and complex. ¡°Because at a glance at the cave here, it is obvious that it was dug by some kind of relatively large star beast, so there are scattered gravels and collapsed stones everywhere in the cave. But if we talk about complexity, the situation here is extremely complicated, that is, the entire cave has no rules at all, and there are no signs that can be identified. For a while, Lin Gu had to jump down and down among the rocks, stepping on the scattered stones to climb over one channel after another as steep as a rock cliff. For a while, he had to wade through a passage that had already been submerged by groundwater, and was almost already flooded. A channel that has become an authentic river. But in these seemingly chaotic environments, Lin Gu discovered an anomaly, which was a mark. For all the students from the Hundred Battalion who entered the underground of Lagu Snow Mountain, they have only two purposes. One way is to go underground in the Lagu Snow Mountain to collect some rare medicinal materials. The medicinal materials here are not the kind of medicinal materials that are considered on earth, but the kind of medicinal materials that can be used by Yuan Dan masters to refine Yuan Dan. It has to be said at this point that everything in the universe sometimes really feels like it leads to the same destination. Although the refining of Yuan Dan mainly uses various precious vitality, the acquisition of this precious vitality still comes from nature and the universe, and medicinal materials are one of them. It¡¯s just that this medicine is not that medicine, but at least on the surface, the two are similar. Due to its special geography and energy environment, Lagu Snow Mountain has become a natural treasure house of medicinal materials, and the underground of Lagu Snow Mountain is suitable for growing some treasures that like to absorb the energy of earth fire and ice. medicinal materials. Therefore, the underground of Lagu Snow Mountain has always been the place where students from the Hundred Camps make their fortune. But equally, there are also potentially extremely dangerous gates to hell. If such traces were placed by other Hundred Camp students, they would definitely not be discovered, because the locations of these traces are very secretive, and in the dim environment underground, it would be impossible to be discovered. possible. Speaking of this, I have to mention one thing, that is, human beings on earth have also entered a period of rapid evolution after entering the cultivation method of the Moro Empire. Or it can be said to be a period of recovery, because humans on earth, which have lasted for tens of thousands of years, have begun to degenerate in some directions. Even in the eyes of ordinary people, this degeneration may be a good thing. But some degradation is definitely not a good thing, and one of them is night vision. Therefore, even if he is tens of meters deep underground, Lin Gu can still clearly see the surrounding plants and trees without using any equipment. But as Lin Gu accumulated Yuanli in the past six months, he gradually began to discover some abnormalities in himself. One of the abnormalities is his sensitivity to the surrounding environment, especially to some special types of vitality. This may come from the Zhenkong Yuan Fu, because the Zhenkong Yuan Fu itself is about controlling the surrounding energy, but Lin Gu is even more suspicious that it may come from the special soul secret magic Yuan Fu located in his head. . Because this feeling mainly appeared after taking the Yuanling Pill, that is, after the first Yuan Rail was condensed in his brain, he found that he became sensitive to the Yuan Qi within a few meters of the surrounding area. Get up, especially for some special energies. Just like when he first entered the Lagu Snow Mountain, he could clearly detect the existence of icy protons around him, and even seemed to be able to touch them. At this time, as he walked along, he found that he could often feel the presence of an abnormal vitality mark in some hidden corners or under a certain piece of gravel. The vitality mark, thisThere is not a very rare method of using Yuan Power on the network of Bingdao Camp, because it is basically a survival rule necessary for survival in the wild. Especially when entering some places where the direction and location cannot be distinguished, like the Lagu Snow Mountain in front of you. Because in the Lagu Snowy Mountains, any compass or electronic azimuth instrument is definitely a piece of scrap iron, because in the Lagu Snowy Mountains, the existence of the magnetic field is as unpredictable as its vitality environment. As for electronic things, that's even more fucked up. Don't forget, electricity itself is a kind of vitality of the universe, so when electronic things enter some violent vitality environment, it is like water droplets entering the sea of ??fire. If they are not directly It would be weird if it evaporated. Therefore, in the Lagu Snowy Mountains, electronic things are of no use at all. In fact, after the Moros entered the earth, especially after the Moros began to plant some special cosmic wood plants on the earth, electronic equipment in many places on the earth became somewhat useless. It¡¯s like entering an area without electronic signal coverage. Therefore, including Lin Gu, after entering the underground, he also began to mark some vitality marks in some secret locations that only he could feel, because this was directly related to whether he could follow the original path out of the underground. Of course, there is a very unique way to set up vitality marks. Therefore, under normal circumstances, as long as the difference in strength is not very big, it is impossible for outsiders to feel the vitality marks set by oneself. But Lin Gu found that he seemed to be able to clearly feel the vitality marks set by others. The so-called vitality mark is actually a cipher text set by one's own vitality in certain positions in a special way that only one can distinguish. It is indeed a cipher text, because there is definitely a lot of information in it. If it is obtained by someone familiar with it, a lot of information can definitely be obtained from these vitality marks. Of course, the number will not be very large. After all, this thing is like A bookmark can never leave too many words. But the reason why vitality marks are so popular in the entire universe is that they are irreplaceable, and they also have a secret that cannot be ignored. At least when Lin Gu checked the vitality marks, he didn't see any record on the Wengdao Camp network that someone could detect other people's vitality marks. In fact, the energy mark is basically one's own energy, but this energy is imprinted on a certain stone or a certain leaf in a special way. The vitality marks left in this way vary according to the level of the person's vitality and the requirements of the person who set it at the time, but the longest, according to the records on the Wengdao Camp, such a vitality mark cannot exceed One year, because the energy contained in such a vitality mark can only last for one year at most. Unless it is some special vitality marking method, the most outstanding vitality marking method in the Wengdao camp only lasts for half a year, and it also consumes energy abnormally. Lin Gu is using this method now. Therefore, after Lin Gu enters the underground, he cannot move forward faster because the level of his six Yuan Rails cannot support his continuous use of Yuan Qi Marks. Therefore, when Lin Gu discovered three other different vitality marks, he already knew that he was not the only one in this path, even though he could not distinguish the energy levels of the owners of these three different vitality marks. Regarding these three vitality marks, Lin Gu said that he was not curious, which was definitely a lie, especially since Lin Gu deliberately avoided it several times but finally bumped into it again. Lin Gu simply followed these three marks and started to go deeper. Go. Because he discovered that these three marks were obviously not from the same place, but every time a certain distance passed, these three marks would reunite at the entrance of a certain branch cave after being separated for a certain distance. In fact, Lin Gu was mainly caused by boredom. After all, in the quiet and uninhabited underground world, if there is no goal, the time will definitely be very difficult, especially when he found that he could follow any of the three marks. You can bypass some dangerous areas. In the underground world of Lagu Snow Mountain, in addition to the tempting medicinal materials for refining Yuan Dan, there are also quite a few star beasts. The most common one is a weird auburn rat that is only the size of an ordinary human head. Although this kind of rat is not big, but when it comes to being difficult to deal with, it is definitely one of the best in the entire Lagu Snowy Mountains, especially their rat nest. If you bump into it, it will definitely be like falling into a frying pan. Clear water makes no difference. Therefore, after almost bumping into it several times, Lin Gu simply followed the three marks and walked slowly in the underground world.In the end, because each of these three marks almost bypassed all dangerous areas, this was absolutely crucial to Lin Gu.
