Looking at Li Li's running back, Lu Yan was a little lost and a little sad, he could understand Li Li's good intentions, but deep down in his heart, he had a trace of rejection of this kind of concern. Pen, fun, and www.biquge.info

Back at the residence, Lu Yan couldn't wait to put the memory card into the computer, the screen was pitch black, occasionally a few white light spots flashed, and gradually the picture began to fade, and in the black environment, it seemed that you could see leaves constantly passing in front of the camera. The camera walked to a low house, and Lu Yan found that this house was the one in the dark forest, and it could be guessed that this card should belong to Luo Yi.

In the video, a man is seen, and the light is too dim to see his appearance clearly.

"Can I go?" This is Luo Yi's voice! Lu Yan hadn't heard Luo Yi's voice for a long time, but he still recognized it at once.

"Have you thought about it? There's no going back. The man's voice was low and hoarse.

"Since I can be here, I must be ready to come to my senses."

A man's low laugh appeared on the screen: "Although we came out this time, you are still our enemy, I will only take you there, but I also hope that you can make some mistakes on the way, haha." ”

"If I die, you won't be able to get there."

"We're already dead once, and nothing can scare us."

"Don't talk nonsense, let's go." Luo Yi was a little impatient.

The screen gradually brightened from almost pitch black, but the outline of the object was still unclear, and this brightness instantly increased, like the birth of the universe bursting out with a strong light, which lasted only about two seconds, and the video began to become erratic, and instantly returned to pitch black. In such darkness, Lu Yan seemed to hear a trace of electricity, like some kind of signal interference, he turned up the volume to the maximum, and could faintly hear a sound coming out, more like a man chanting, as if it was a spell in a horror movie, Lu Yan tried his best to distinguish but only heard the words "bird language, cave, answer". After this sound, the video also came to an abrupt end.

The content of the video is not difficult to understand, judging from the first half of the video, Lu Yan can be sure that Luo Yi came here voluntarily, and she did not use the shuttle, but used those people to pass through methods that she did not know yet. But the man's voice at the end of the video is puzzling, what do the words "bird language, cave, freedom" mean, and who is the man who spoke? Lu Yan didn't have a clue about this content, he thought of Landi's helper, hoping to get inspiration from it.

"Hello sir."

"Do you know what the words birds, caves, and excitement mean?"

"Hello sir, do you want to go on vacation, I have included information on all the attractions on this planet here, you can search according to the keyword. But I guess if you're asking me, you're not trying to get a literal explanation. ”

"Three-word association."

"Literally, those three words should be related to vacation."

For Landy's answer, "Search for bird language, including all homophones." ”

"Sir, I searched for all the words and events related to bird language, and there are about 110,000 results in total, but I think if you are looking for any clues, it must be related to the company, filter out the distractors, and there are four results in total. One is the Santang Zoo, which used to be one of the company's properties, but the Santang Zoo was closed seven years ago due to a poisoning incident; The second is the Department of Biolinguistics, which is a department set up in conjunction with Santang Zoo and has long since ceased to exist. The third is Mt. Toba, which is 70 kilometers outside the city, and has not yet been officially developed, and the fourth is the Wings Project, which is a research project on biomimetic wings that has just started within the company. Sir, I don't know if the bird language you are referring to is among them. ”

"Mt. Toba? Tell me the details. Of these four results, it seems that only the third "Toba Mountain" can match the cave, and if it is related to the company, it must be here.

"Mt. Toba, 73 kilometers away from the company in a straight line, covers an area of 856 square kilometers, the highest peak is 770 meters above sea level, covered by primeval forests all year round, the mountain is currently uninhabited, and there are no artificial buildings on the mountain."

"Is there a cave on Mt. Toba?"

"There are 73 large and small caves in Mt. Toba, and if you limit the conditions to a diameter of 5 meters or more, there are a total of 4 large caves with a depth of 50 meters or more."

"Give me information about the biggest cave."

"The main cave is 440 meters above sea level directly east of Mt. Toba, and the diameter of the cave entrance is 23 meters, so there is no depth data at this time."

"Landi, did you say that Mt. Toba is an asset of the company, does it include the entire mountain?"

"Yes sir, Bird Language Mountain is the land that the company acquired through auction seven years ago, and at the same time, it also acquired a 5 square kilometer urban land in Huajie Town."

"Flower Street Town? What is it? ”

"It's a town 19 kilometers northwest of here, and the site is currently under development, and a comprehensive mega hospital is being built."

"Do many places have the company's land assets?"

"Sir, your company is one of the largest trading companies in the world, we have development projects in more than 70 countries around the world, including many undeveloped reserve land, including forests, wetlands, urban land to be developed and other types, and even we have the right to use and develop a quarter of the area of the red brown desert, the company's development tentacles extend to all parts of the world, let us ...... for the development of this planet"

"Enough is enough, I've heard these impassioned introductions many times." Lu Yan interrupted Landi's introduction, "What kind of development is Toba Mountain used as a backup resource?" ”

"Sir, you don't have access to this information?"

"What?" Lu Yan was a little surprised by Lan Di's answer, he didn't expect that this kind of information would also have a level of confidentiality, but Lan Di took the initiative to tell him about the development of Huajie Town, which was really confusing. Lu Yan also inquired about several reserve lands in other areas of the company, and all of them successfully inquired about the relevant information.

Lu Yan didn't ask any more questions. "Toba Mountain, Cave, Freedom", these three words seem to have a slight connection now, and Lan Di's tight-lipped about Toba Mountain also seems very unusual, Lu Yan believes that Toba Mountain must be hiding a secret that cannot be told to others, maybe he can find out the reason for Luo Yi's departure there, and the doubts he has encountered in so many days will be solved, it seems that he must go there for a while.

Before dawn in the early morning of the next day, the contour lights of the road were still not turned off, and Lu Yan stepped into the paddle machine assigned to him by the company with his tools. Lu Yan has no experience in professional mountaineering, and he doesn't know what professional equipment is needed for mountaineering, and he has only climbed scenic mountains, many of which are still going up and down by cable car, and he is not prepared for what kind of environment the undeveloped mountain is, so he can only stuff all the tools he can bring into his backpack. Lu Yan set the destination coordinates on a rock platform without plants about 300 meters away from the main cave, set the paddle machine to automatic mode, less than half an hour, the control computer of the paddle machine came to the sound of "about to arrive at the destination", Lu Yan looked down along the porthole, he was already in a group of mountains, the mountains were one after another, the mountains were filled with heavy fog at this time, and the green plants on the mountains were almost invisible. Lu Yan felt that the paddle machine was slowly descending, and the forest in the mountain gradually revealed its original face, and the green plants covered almost the entire mountain, and when the paddle plane descended to a certain height, he saw a small yellow clearing in the center of a piece of green, which was the landing place of the paddle machine.

The paddle machine accurately stopped on a rock of less than 10 square meters, Lu Yan walked out of the cabin, and the smell of grass mixed with soil instantly penetrated into his nose, although the fog was filled at this time, but Lu Yan did not feel a trace of cold, he put on his backpack, pulled the neckline, and walked towards the cave according to the instructions of the navigation. Walking out of the huge rock, Lu Yan finally stepped on the soil of Mt. Toba, which is different from the black soil that Lu Yan is familiar with, perhaps because it contains a lot of certain elements, the soil here is purple-red, and the hardness is also very high, and it does not become soft due to water vapor, Lu Yan smoothly moves forward along the path, although it is daytime, but the tall trees in the forest shade the sky and the sun, and Lu Yan must turn on the strong light to see the road clearly. Lu Yan staggered among the trees and weeds, most of the plants here had never been seen, most of them looked weird, and the variety of colors was much richer than his impression, Lu Yan did not dare to touch it easily, so he could only wrap himself in his clothes to avoid direct contact between his skin and plants. The further you go, the stronger the smell of corruption in the air, presumably the ground under your feet must have accumulated thousands of years of dead branches and leaves.

Lu Yan cautiously walked all the way, walking for about a kilometer, the sense of fear and doubt in Lu Yan's heart became stronger and stronger, this Toba Mountain seemed ordinary, but the more uneasy Lu Yan felt in his heart. In this long kilometer, Lu Yan didn't see a single animal, not even an insect, nor did he hear any birds and beasts, only the sound of leaves being blown by the wind can exist here, and occasionally sunlight can penetrate the stacked leaves, but there is no life in the sunlit area.

It's like a forgotten forest.

Lu Yan had the courage to continue to move forward, and only by watching the continuous approach of the target location on the recorder could he relax a little. When Lu Yan turned over the low bushes and bypassed the ancient trees that were so thick that the three of them couldn't hold them, suddenly a "Di Di" was extremely harsh in this cookie-cutter forest, Lu Yan was startled, immediately stopped, looked around and found nothing unusual, he checked his personal equipment, and it was all working normally. Perhaps it was the deep atmosphere of this forest that caused him to hallucinate, Lu Yan tentatively continued to move forward, and within two steps, a crisp "Didi" broke into his eardrum again, Lu Yan was sure that this time it was not an illusion, he really heard the cry, and he was sure that it was the sound made by electronic components.

Lu Yan stood in place, and after about 15 seconds, the sound of "Didi" remembered again, and Lu Yan judged the direction and walked in the direction of the source of the sound. The sound of "Di Di" has been maintained at a frequency of 15 seconds, as Lu Yan approached step by step, the sound became clearer and clearer, and the two blades the size of wheels in front of him were set aside, Lu Yan felt that the sound of "Di Di" was beside him, he limited the search radius to 5 meters, and found that there seemed to be a faint blue light behind a piece of grass, Lu Yan pushed aside the weeds, and a rusty little robot was tilting its head against a tree root, the robot was about half a meter in size, and it seemed that it had been here for a long time, The small half has been buried in the soil, the blue light comes from a small indicator light overhead, and the "tick" sound also comes from this, perhaps it is the occasional sunlight that allows his solar panels to absorb energy, so that the indicator light has been working until now.

The moment Lu Yan stepped on the grass and soil, he felt that the ground under his feet was harder than the dirt in the forest, and he stomped his feet hard, feeling that there were many sharp protrusions on the ground, he squatted down and found that a thumb-sized metal cone appeared on the dirt floor that should have been flat, which was an artifact from the shape, and Lu Yan was full of doubts about how there could be metal in the soil. He took out the small armory shovel he carried with him to dig up the soil little by little, and the metal cones were exposed more and more, Lu Yan hit the metal cone with the shovel, and the feedback force shook the palm of his hand, but the metal cone still did not move, seeing that most of the metal cone was still in the soil, Lu Yan gave up and continued to dig, he put the little robot back into the grass from the new, and at the same time as the small robot was straightened, his headlamp reflected a strong light when it hit the grass, Lu Yan pushed aside the grass, and the scene in front of him stunned him. In front of me is a large open space, full of waste metal parts, like a robot graveyard, countless robot corpses are lying here in a mess, most of them have been rusted to the point of incompleteness, many parts of the robot's body are buried in the soil, this circular field is about half a football field, and there are about thousands of robot corpses piled up in the black press, this field is obviously excavated by hand, but who will dig out a vacant land here to stack robots, Landi once told himself that there is only vegetation here, no artificial habitation, So who would transport the robot all the way here?

Lu Yan looked at his recorder, which was only about 200 meters away from the entrance of the cave, and he had no time to take care of these robots, so he followed the direction of the recorder and walked towards the active entrance. Although the distance is less than 200 meters, he needs to climb a huge ramp in these 200 meters, and he struggles to walk through the mountain with trekking poles, and it takes about half an hour to complete the 200 meters, turning over a large rock more than one person high, and the recorder shows that "you have reached your destination".
