Lu Yuan didn't know how he fell asleep in a daze last night, but he must have been woken up by freezing this morning.

Picking up the snowdrift that can cover the hare overnight, Lu Yuan stood directly on the roof of the car when he climbed out of the carriage, and looked around, in addition to the distant cliffs were also dotted with a bit of precious dark green, the night passed, and the snow field was frosty white again, erasing all the fragments and broken armor scattered all over the place yesterday.

Lu Yuan jumped and moved the muscles and bones that were a little stagnant, in order to save the power of the exoskeleton, he only adjusted the thermostatic membrane to the minimum standard for maintaining body temperature, Lu Yuan must be prepared to use the exoskeleton battery to forcibly power the hare after losing the hydrogen rod, and using less is a little.

The same thing. Lu Yuan obviously had a self-heating food packet, but he still chose to eat the nutrients that tasted the same chewing wax, and now anything that could provide calories was precious.

Fortunately, Lu Yuan carried the materials back to the carriage as much as possible yesterday, especially the spare parts attached to the drone.

Taking advantage of the fact that the morning glow had just come out and the sun was in full swing and the wind was small, Lu Yuan hurriedly debugged the drone and retrieved and detected the hare falling area, but Lu Yuan did not bring a cumbersome temporary geological detection when he left the Xiyun, but brought sufficient combat components, so the drone only had the simplest search capability at medium and low altitudes.

Lu Yuan himself did not hope to find the fuel tank with the drone, and once the wind rose, the drone was also scrapped. But according to aerial reconnaissance, Lu Yuan still found the trajectory of the wreckage.

Retracting the drone, Lu Yuan set up an anti-gravity module to ensure that the hare would not be completely covered by snow when he left to find the hydrogen rod fuel tank.

The paratrooper rifle was hung next to the backpack, and Lu Yuan tightened the strapping belt and put a few fast-acting anti-radiation agents into the pouch on the side of the bag. After passing through the deep forest of the Black Snake, the radiation level of the snow rose faintly, and Lu Yuan couldn't help but think of some disturbing history.

Air-burst dirty bomb, that's what Lu Yuan thought of. The dispute between the Celestial Alliance and the Empire has been going on for centuries, and it is fitting to call this long war "Skyfall." From melee lightning strikers to antimatter annihilation cannons, surface warfare began with air-blasted dirty bombs in deep space, until new combat suits filtered out contaminants, and a more extinct deadlight was developed.

Just reading the text of the transcript is enough to silence a person. Anyway, Lu Yuan couldn't imagine what kind of intense radiation energy could reach the point of causing communication failure. Pushing himself and others, Lu Yuan was reluctant to guess the part of the Earth that was so far away that most of the records were lost.

After walking along the cliff for about a kilometer, the silhouette of the hare disappeared into the growing snow. Lu Yuan determined the position of the compass and the signal reception, and continued to search along the spot where the hare rolled downhill yesterday.

The exoskeleton also needs to heat the paratrooper rifle to replace antifreeze. Walking along the cliff, Lu Yuan didn't say that he was vigilant for 120,000 points, but there were seven points after all. Yesterday, the black beep almost made Lu Yuan confess, and it was completely impossible to predict what kind of dark peep was hidden on such a mountain wall.

Nearly noon, the wind and snow covered the sun, and Lu Yuan passed over the outermost piece of hare fragments found by the drone. If you go out again, you will be beyond the radius of activity, and you will be on the snowfield at night without shelter, and you will know with your ass that it is purely nine deaths.

Lu Yuan had no choice but to return, he was a little tired after walking for half a day, and the weather would only get worse in the afternoon, so Lu Yuan decided to find a shelter to rest for a while. There was a rather tall cedar tree under the cliff dozens of meters away, and Lu Yuan threw the probe ball and repeatedly confirmed that there was no danger before hiding next to the tree.

Avoiding the limelight, Lu Yuan was able to open the helmet, seize the time to bite a few mouthfuls of nutrients, and swallow it with hot water. The biggest advantage of this concentrated food specially developed for the war zone is that it is extremely easy to digest and absorb, that is, there is no need to waste time and energy to excrete. After all, the planet's surface doesn't look like a good place to lift your pants.

Lu Yun calmed down for a while, and looked at the strange pine trees that grew strongly in the cracks of the mountain cliffs with a slight sorrow. If they don't hold on and choose to fall, then when the hare falls down the cliff, there will be no block, and it will fall vertically at a height of tens of meters, and the steel and iron bones of Lu Yuan can't stand it.

Lu Yuan turned his head, thinking that the fuel tank might be hanging from the canopy of the cliff side, and there might be an unexpected joy when he searched for it on the way back.

After resting for a quarter of an hour, Lu Yuan began to search close to the root of the cliff, Lu Yuan deliberately put his pace heavier, so that the multi-purpose scanner he carried with him could be investigated more deeply, and after walking for more than forty minutes, the scanner really sounded "Di Di Di".

After Lu Yuan threw the gun over his shoulder, he flicked off the folding sapper shovel and dug about half a meter under his feet, and he really dug out a hydrogen rod!

Lu Yuan's throat moved, but he didn't dare to touch this glowing hydrogen rod. This thing is not in the fuel tank, it does not increase its inertness, only a layer of force field to restrain it thinly, and when it is hit by a violent collision, the force field breaks, and the hydrogen rod also explodes. As for the power, presumably the black snake with no bones left has a lot to say.

Lu Yuan carefully pinched the hydrogen rod, the layer of force field was like a page of tin foil, wrapping the melt-in-mouth crab stick, Lu Yuan used the small anti-gravity field of the exoskeleton to hold up the hydrogen rod, re-strengthen its force field, mark the signal point, and then put it into the snow.

Lu Yuan remembered that he had closed the fuel tank after throwing the hydrogen rod, but it was not locked according to the standard procedure, even if he threw a few hydrogen rods on the edge, the main parts should be bound by each other's force fields, thinking about it, the fuel tank should be nearby.

Things went a little smoother than Lu Yuan expected, and he walked less than 100 meters forward according to the location where the hydrogen rod was buried, and the scanner issued another warning.

According to the direction of the scanner, Lu Yuan turned around, huh? Facing a cliff?

The scanner must not go wrong, Lu Yuan threw out the probe ball, and this little clever ghost who could ignore the terrain suddenly rubbed against the mountain wall and disappeared. Within a few minutes, Lu Yuan was rewarded, and there was a place on the mountain wall where the snow thickness was significantly lower than average, so Lu Yuan directly manipulated the scanning ball to try to pass through the snow layer.

With a soft "click", the probe ball really passed through, the ball spread its wings, vibrated and flew very fast, and infrared rays came out to explore this hidden deep cave, bending and twisting around a few corners, and the probe ball really tracked to the signal source of the scanner.

Lu Yuan's spirit was shocked, but his heart immediately tensed, the fuel tank did not have long legs, and this hidden cave was not a steep slope, it must have been brought back by some creature that lived here.

But that end is the Longtan Tiger's Den and you have to break through, without the hydrogen rod, Lu Yuan doesn't want to drive the hare, and the exoskeleton energy is purely to quench your thirst.

Adjusting the probe ball to automatic life checking, Lu Yuan picked up the snow outside the cave, and by feeling, it was to accumulate thickness overnight. Most likely, the cave creatures heard the hydrogen rod explosion and the hare rolling quietly, crawled out to observe, and then retrieved the fuel tank.

Lu Yuan temporarily turned off the odor removal of the exoskeleton air filtration system, and he sniffed the air while examining the cave walls.

The walls of the cave were normal rocks, not to mention that they were covered with some kind of secretion fluid and oocynoma like the pine trees in the deep forest of the black snake, but as Lu Yuan gradually went deeper into the cave, there was a foul smell in the dull and turbid air, and Lu Yuan endured nausea and breathed several times, and his intuition told him that this smell did not belong to reptiles, but more like the smell of hair and feces emitted by large mammals.

Lu Yuan stepped on the tactical catwalk, held the barrel handguard in one hand in order to point quickly, calmed his heartbeat and breathing, slowly opened the exoskeleton to silence, and dived into the depths of the cave like a ghost.

The probe ball hadn't reached the end of the cavern yet, and it was probably winding its way through the entire belly of the mountain. But it didn't take that long, the probe ball had stopped at the strongest point of the signal, and through infrared and heartbeat double detection, it was determined that there were at least three true animal subclasses with a body length of more than one meter, in other words, bears.

Paratrooper rifles generally use 4.7mm standard caseless bullets, focusing on the killing of soft targets, and in the face of armored infantry, they use a 6.5mm heavy barrel that they carry on their bodies, which can penetrate 15~20mm infantry special bulletproof armor when firing tungsten core armor-piercing bullets. So for the sake of insurance, Lu Yuan got an armor-piercing bullet.

The detector ball screen shows that the fuel tank should be in the middle left position of the three-headed bear, but Lu Yuan can't use a grenade, but this is not a big problem.

Approaching the corner next to the bear's den, Lu Yuan probed and saw at a glance the fuel tank that was played by the three sturdy bears as skulls. Of course, Lu Yuan knew that bears were solitary habits, and these three bears must be bear cubs, but they were too strong. And, what about the she-bear?!

Lu Yuanxin said that if you don't sleep in the winter, you have to wander around blindly, even if you wander blindly, you have to pick up things blindly, and I don't want to harm you, but my universal translator is not strong enough to speak bear words, so I have to say that this is fate.

The probe ball flew to the middle of the nest, and suddenly exploded several strong flashes in succession, startling the bear cub to roar continuously, and all of them stood up towards the probe ball man, showing their teeth and claws.

This is what Lu Yuan wanted, aiming at the back of the bear cub closest to him, two point shots were shot, and a puddle of blood immediately burst out in the dark. The bear didn't snort and fell to the ground and died.

Attacked from behind, although the remaining two bear cubs reacted extremely quickly, they still inevitably had the young combat experience of the cubs, and their first reaction was not to rush, but to turn around and roar, slapping their chests. In response to them, it was naturally Lu Yuan's ruthless armor-piercing bullets.

The two bear cubs roared angrily, and started to run against Lu Yuan's shot, which shook the cave and rumbled, but the momentum couldn't hurt anyone, Lu Yuan calmly shot a point, and the bullet hit the bear cub's eyes and nose like he had eyes, and the bear cub had just accelerated with force, and he couldn't support it and fell to the ground.

Lu Yuan put on a new magazine, and I have to say that the vitality of these bear cubs is really strong, and they have not breathed after being hit by more than a dozen heavy bullets in a row. But Lu Yuan was not interested in mourning for them, and continued to replenish the guns remotely until it was confirmed that they were completely killed.

The smell of bear blood lingered on the tip of his nose, and Lu Yuan stepped past the bear corpse, lifted the fuel tank covered with claw marks, and let out a long breath.
