I have no pheromones, you smelled wrong

There is no one on the snow peak, and the unmanned detector is dispatched again to scan and search whether there are still buildings left by humans hidden in the mountains.

The detector did not find anything on the surface, and the overly thick mountain blocked the detection wave from going deep. It could only be barely confirmed that there might be a space in the mountain, but it was impossible to determine whether it was a naturally formed hollow or a trace left by human technology.

Lin Xu stared closely at the three-dimensional projection of the mountain peak drawn by the detector on the light screen, thinking about where he would choose the entrance of the base if it were him.

The outdoor environment of the earth 3000 years ago is full of strong radiation left after nuclear wars. It is a smart and economical way to hide the base in the mountains, but they must dig very deep and confirm that the ground is stable and no collapse accidents will occur.

Appropriate water and ventilation conditions are also required.

On the snow peak, there are few signs of life, but mutant animals, plants and zombies that will actively attack humans will not be frightened by the low temperature and cold wind. The entrance of the base must be easy to defend and difficult to attack.

And it should be close to the route where the stele was brought down by ice erosion.

Lin Xu delineated several directions with the help of the scanning map, and sent out unmanned detectors again, and found the entrance of the base covered by the icefall in one of them.

Lin Xu decided to go in.

Heinrich didn't ask Lin Xu why, but asked Arnold to send more weapons and equipment up. The two drove the aircraft around the steep rocks and landed on the open space next to the entrance of the base.

There is a thick layer of ancient ice here, strong enough to support the weight of the aircraft on the ground.

The entrance of the new base was built very close to the top of the snow peak, but a short walk to the west is a pass, and the personnel in the base can quickly pass to the areas on both sides of the ridge.

But this is a story from 3000 years ago. Now, the stone tablet engraved with the name of the new base is brought down the mountain by ice and snow, and the dark gray entrance is frozen and covered by the condensed ice waterfall. texture.

Lin Xu checked the snow accumulation above and below the icefall, and after confirming that opening the icefall would not cause an avalanche, he and Heinrich used the power-enhancing function of the powered exoskeleton to cut through the ice.

The gate reveals the whole picture, but it has been preserved extremely well by being frozen all the year round. The material used is some kind of dark gray alloy with a rough surface.

Heinrich watched Lin Xu's hand stroking the door, just like he stroking the stone tablet, "Shall we pry the door open?"

"Do not."

There is an electronic screen with external buttons embedded in the left door. This thing is almost invisible in the interstellar era. Only some remains of the backward planet on the edge of the Dionysus region.

The low temperature on Xuefeng caused the battery of the electronic screen to be scrapped early and could not be used.

Lin Xu turned around and groped around the steel corners on both sides of the gate.

The doomsday base also uses an electronic system to control the access control, but energy has always been an extreme headache for the people in charge of the base. In order to avoid the disorder of the access control system caused by energy outages, a mechanical system is generally equipped.

click-

Lin Xu felt a circle of gaps, pushed in lightly, and a round iron cover bounced off the wall, revealing the number buttons below.

Hopefully the password he used back then will continue to work.

Standing behind Lin Xu, Heinrich watched as he found the button almost intuitively. After inputting a long series of complex numbers, the alloy door swung open before their eyes, and the shaken ice and snow fell down.

Suddenly the wind swirls into the darkness that widens as the gate opens.

A long tunnel awaits ahead.

"Have you been here?"

"No." Lin Xu pursed his lips after answering, and said, "I... have been to the old base buried under the lake, many years ago. Go in, be careful, I don't know this How's the situation on the sidelines?"

What do you mean many years ago?

Heinrich had too many doubts about Lin Xu, but at this moment they were all suppressed in his chest.

He found that Lin Xu's voice was low but had a sense of suspension, and Lin Xu himself had endless questions and wanted to find answers.

Because they could not confirm the air circulation inside the tunnel, the two put on oxygen masks and walked forward with flashlights and light energy guns at the same time.

Lin Xu held the flashlight with his left hand down, and his right hand held the gun lightly on his left wrist to reduce the impact of possible recoil. His knees were slightly bent, and he lowered his center of gravity and moved forward cautiously.

Heinrich was almost certain that Lin Xu had received professional training.

Previously, he only knew that Lin Xu had a wealth of actual combat experience through Lin Xu's fighting skills and fighting awareness in "Xing Hai", but the actual combat experience may or may not come from individual summaries.

However, Lin Xu's current gun-holding posture is widely adopted by marine troops and field law enforcement officers, and is taught as a standard course.

This is not a specific rule that can be learned by scratching the surface of a bullet.

Under whom did he train?

The alloy door was open, and was poured into the strong wind. The temperature inside the tunnel was warmer than the outside, and there were still water stains on the rough ground. Now the low temperature brought in by the cold wind froze, and all of them turned into ice slag.

The gate drew the light into a square shape, and now, the square light was gradually moving away from the two of them, and the strong light from the flashlight pierced the thick and cold darkness ahead.

The ground and walls of the tunnel are all undecorated stone walls, and every other section will be supported by metal brackets to support the mountain wall as reinforcement. Wearing heavy exoskeletons, the sound of the two falling footsteps echoes very clearly in the long and narrow space.

Other than that, there was no other sound, not even the sound of the wind.

Lin Xu smelled a cold, rusty smell.

The oxide layer of the alloy bracket was corroded, and a layer of purple-red rust wrapped around the corners.

This tunnel is like the esophagus of a long snake, narrow and dark, with no end in sight, and the end of the flashlight's light seems to be submerged in the darkness that can swallow people.

In fact, the light of the flashlight illuminated the lampposts on both sides of the stone wall during the exploration, but they couldn't find the switch, and they didn't confirm whether the human mountain base still had energy to light the wall lamps.

Just when Lin Xu felt that walking mechanically in this tunnel almost made people forget the passage of time, a breeze came oncoming, and the flowing air indicated that there was a new space ahead.

He and Heinrich glanced at each other, quickened their pace tacitly, and moved forward against the wind.

The beam of light emitted by the flashlight suddenly broke and dissipated into the air——

The bright light rushed towards the face, blurring the vision of the two people who walked out of the darkness for a moment. After gradually recovering, a huge circular space came into view.

Through visual rough estimation, the area of ​​the annular space is enough to be the size of a standard stadium, and the internal height from top to bottom is close to [-] meters. It is like an enlarged version of the ancient Roman Colosseum. The tunnel can reach a road in the middle of the space Loop corridor.

Daylight is brought into the room from the outside of the mountain through the refraction of the mirror on the top, illuminating the only two materials used in this underground building. The cold rock and steel are silent in the sunlight, and the fine dust floats and falls in the light and silence.

Lin Xu's expression was almost blank. He walked to the railing of the circular corridor and looked down. There was a three-story podium on one side of the central circular space. The smooth stone wall behind the podium stretched upwards obliquely. Heavy pressure, always dumping and crushing on the speaker.

However, a huge flag hanging down from the top of the stone wall relieved this sense of oppression. On the dark red faded damaged flag, the diamond-shaped logo of the Eastern Region Base could be vaguely seen.

The open space under the podium was full of water stains, and the metal floor slowly grew purple-red rust under the low temperature, making it even more sparse.

This is a work delivered by the last industrial and technological power of human beings on the earth, accompanied by a strange combination of unadorned roughness, oppression and cohesion.

It has been abandoned for many years.

Nature and time are invading, but haven't been able to completely destroy it.

But in the huge space, there were no corpses, no traces of battle, even the rows of seats under the podium were arranged in neat horizontal and vertical lines, only tranquility, chill and metallic breath flowed past.

According to the layout and construction habits of the old base, the personnel living area will be on the upper floor of the building.

"This way." Lin Xu called Heinrich, and walked forward along the circular corridor to find the stairs all the way up. After passing through the third floor, he entered a closed circular corridor with rooms facing each other on both sides of the corridor.

There is a metal card nameplate in the center of the door of each room, marking the owner of the room.

Lin Xu stood in front of the nearest door. There were six names on the nameplate. The door lock was an ordinary lock that could be opened with a key. He raised the light energy gun and pointed it at the keyhole and fired.

After a dull gunshot, the door lock was completely broken. Lin Xu pushed the door open, and what came into view was an ordinary small room with three bunk beds and six desks.

No bed bedding and personal household items could be seen. The low temperature, hypoxia and few microorganisms in the snow mountain base made the appearance of the beds, tables and chairs relatively intact.

Heinrich received Lin Xu's gaze, and also used a light energy gun to break the door lock, and pushed the door open.

Same layout, same emptiness.

Where did the humans who used to live in this base go?

Join the Ark Fleet and leave?

But what Lin Xu can confirm is that the cultural context of the empire is very different from that of the Eastern Region, and even the official language of the empire has obvious traces of Romance languages.

The imprint of the Eastern Region is rarely seen in the empire.

Lin Xu gestured to Heinrich, and the two opened three more rooms. After confirming that the layout of the six rooms was similar, they climbed up a few floors and found the location of the single room.

There should be high-level personnel of the new base living here. Lin Xu quickened his pace, confirming the names on the nameplates one by one, trying to distinguish whether there were names he was familiar with.

Suddenly, he stopped in front of a door. Looking at the name on the nameplate, Lin Xu's eyes widened slightly, and he even stretched out his fingers to press the nameplate, proving once again that his eyes were right.

—— Yan Yuan.

Back then the Chief Physician was in charge of Lin Xu's supernatural transformation, and Yan Yuan was the Assistant Physician next to the Chief Physician. He was born in the war years, very young, but smart enough to be a member of the transformation plan at a young age.

Lin Xu remembered that Yan Yuan was a good boy who loved to laugh and was a little timid.

"Do you want to open this door?"

Heinrich found that Lin Xu was almost frozen in place.

"En." Lin Xu nodded very lightly, and Heinrich stepped forward, raised his gun neatly to destroy the door lock, and opened the alloy door for Lin Xu.

The light of the flashlight fell into the room, illuminating the blank single bed board and the desk with some paper products.

Heinrich touched Lin Xu's arm to remind him that he could go in. Lin Xu regained his senses, stepped into the room, and walked straight to the desk.

Several notebooks were neatly stacked and placed in the upper left corner of the desk. It could be seen that the owner of the room left after packing everything up, and he did not act in a hurry.

Lin Xu took out the one with the most pages and opened it gently so as not to damage the brittle and yellowed pages.

With the passage of time, the ink stains are also fading, but Lin Xu can already confirm that this is the handwriting of the Yan Yuan he knows.

Yan Yuan learned a doctor's special font from the chief physician, and it was scribbled around. Lin Xu needed to keep his eyes close to the page for a long time before he could understand it.

"Sizzling—"

The sudden sound made Lin Xu look up at Heinrich. Heinrich was standing in front of two iron safes in the corner, holding a laser knife in his hand. He directly burned the safe with the laser and took out the file bag inside. .

Heinrich met Lin Xu's gaze with a serious expression, his shoulders and back muscles tensed, as if he was examining something.

Lin Xu's eyelashes trembled.

"Zi... hiss..."

The glowing laser knife was put away, and nothing was cut.

Heinrich and Lin Xu faced each other without any dialogue or movement.

"Ho... ho hiss..."

But the weird sound was still coming from the dark corridor.

"Did you hear that?"

Under the cold light of the flashlight, Lin Xu made a gesture to Heinrich.

The author has something to say:
