"The power of this military crossbow is much greater than I imagined, but unfortunately I have to reload the crossbow arrows every time I shoot, if only it could be like a pistol, it would be nice to be able to load a few more arrows at a time." Zhou Yunfeng took the crossbow and nodded with satisfaction.

Just now he loaded a crossbow arrow, tried it with the corpse of the polluter in the yard, stood at a position of about ten meters, aimed at the head through the scope, and shot an arrow enough to penetrate the skull, as long as the shot is accurate, an arrow can get a polluter, but the distance cannot exceed thirty meters, if it is more than thirty meters, the crossbow arrow shot is not powerful enough to penetrate the skull, it is best to control it within twenty-five meters.

Although military crossbows can not be fired continuously like guns, there is also an advantage, the crossbow arrows shot can be reused when they are retrieved, they are divided into two barrels of crossbow arrows, a total of forty, as long as there is no way, the crossbow arrows can basically be recovered after shooting, until the arrows are damaged and can no longer be used.

In addition to the crossbow arrows, there are several packs of steel balls, which are also equipped with military crossbows, but this kind of steel balls are not penetrating, and even the skin of the polluter is difficult to penetrate, and the practicality is very small, unless it is accurately hit in the eye and shot into the head through the eyeball, but this difficulty is not ordinary.

"If the military crossbow is not very powerful, I will not come here for a special trip, but there is only one pistol, you can use it, it will be harder for me to die than you." After Lu Xing finished speaking, he threw the pistol to Zhou Yunfeng.

"I don't use it! I've never used this thing before, and it's only fifty rounds of ammunition, and it's gone when it's done, so I guess a lot of bullets are wasted with my marksmanship. "It's the first time Zhou Yunfeng has touched a real gun, and he is completely a layman, and he doesn't even know where the insurance is.

"I haven't used a real gun either, I just know a little bit of theory, it's not much better than you, or you use it first, if the real marksmanship is too bad, then try me." Lu Xing insisted on letting the pistol out, and Zhou Yunfeng no longer refused.

"By the way, you first make a wooden frame according to the shape of this triangle, and the three corners with grooves can be placed on the crystals, and I am going to do a test." Lu Xing was about to start the engine on the road, when Zhou Yunfeng suddenly took out a piece of paper and interrupted.

The triangle on the paper was drawn on the gold page, and he had copied one according to the angle, but now that the crystals were three, he could try to place them according to the gold page and see what the effect was.

Lu Xing took the paper and looked at it, and asked suspiciously: "What is this, what is the purpose?" ”

"I don't know, I just saw it in the foreseen picture, the details are not clear, I originally had two crystals, plus yours is just right to try, make this first and then hit the road." Zhou Yunfeng explained, he also wanted to know the meaning.

"Okay." Lu Xing nodded, opened the door and walked to the back compartment, took out the toolbox and a wooden board from it, and began to cut according to the pattern on the paper.

About half an hour passed, a triangular shelf was completed, the angle was the same as on the paper, Lu Xing put the tools back in the back compartment, returned to the driver's seat, and threw the things to Zhou Yunfeng: "It's done." ”

"Your craftsmanship is really exquisite, very good!" Zhou Yunfeng took the simple wooden shelf and compared the triangles on the lower gold page, the angles were basically the same, and the three corners were each with a diamond-shaped concave hole, which was just right to embed and fix the crystals on it.

When Zhou Feng put the three crystals on the concave hole, Lu Xing also started the off-road vehicle, turned around and drove back, aiming for the nearest highway.

Zhou Yunfeng's hometown is more than 500 kilometers away from the city, if everything goes well on the highway, it can be reached in about seven hours, it is safer to take the highway, when the earth changes dramatically, basically everyone stays at home, it can be expected, there are few cars on the highway.

Moreover, highways are built in sparsely populated areas, and even if there are few polluters, it is inevitable to pass through some villages and small towns on national highways, where there are many people, and the worst thing is that the army has not yet had the time to clean up, and has concentrated its forces on the most densely populated urban areas.

It is a very dangerous area, so it is better not to take the national highway as much as possible, unless you have to do so, and although it is not completely dangerous, it is much less risky than taking the national highway.

…………

After two hours of driving, they finally reached the entrance of the highway and got on the highway smoothly, encountering polluters along the way, but there were powerful Humvees off-road vehicles, and they went on a rampage and quickly shook them off.

Zhou Yunfeng sat in the passenger seat, picked up a crystal on the wooden frame, compared the record on the small notebook, seemed to have found something, the corners of his mouth turned up slightly, and said secretly in his heart: "That's really the case!" The speed at which the crystal absorbs the radiant energy is almost half as fast! ”

He was vaguely aware of this an hour ago, but he was not sure yet, and he didn't know how much faster the absorption speed was, and after several records and comparisons in the next hour, it was already confirmed.

Now he finally understands that placing the crystals according to the pattern on the gold page can play a role in accelerating the absorption of radiation, increasing the absorption rate by half, which is very considerable for him, so to speak, now three crystals are equal to the original absorption of four and a half, but it has to be enough to make up three, and one less has no acceleration effect.

And one more is estimated to have no effect, but this is already very good, and now he should be the only one in the world who knows this secret, which means that every three crystals he can use equivalent to four and a half other crystals, and get half more benefits.

"I've made a big discovery! Crystal came to a conclusion according to ......", and he told Lu Xing as soon as possible.

"Well, it's indeed a big discovery, this crystal is more mysterious than I imagined, I didn't expect this kind of law to exist." After listening to Zhou Yunfeng's conclusion, Lu Xing also felt a little surprised.

Regarding the acceleration law of the crystal, after Zhou Yunfeng and Lu Xing discussed, they did not plan to reveal it for the time being, and they would decide it later depending on the situation, everyone was a little selfish, and the two of them were no exception.

What's more, this information may be able to be exchanged for huge benefits, they believe that many people are willing to pay a big price to exchange this information, although the role of the crystal has not yet been officially announced, but the secret circulation will definitely not be stopped, after a long time everyone will know the preciousness of each crystal.

…………

After discovering the acceleration law of the crystal, Zhou Yunfeng leaned back on his seat, closed his eyes, and was in a very good mood along the way, feeling that things were developing in a good direction, but after only being happy for more than two hours, the off-road vehicle suddenly stopped.

"Huh? How do you park! Sensing the car stop, he opened his eyes and turned his head to look at Lu Xing.

Lu Xing didn't answer, just stretched out his right hand and pointed ahead, Zhou Yunfeng looked ahead when he saw this, and immediately understood what was going on.

There was a tunnel ahead, but the problem was that the tunnel had collapsed, there were rubble everywhere, and the way forward was blocked.

"Damn! It's collapsed! Zhou Yunfeng looked depressed, he didn't expect to encounter this situation at all, and on the way back to his hometown, he encountered a problem after only a third of the way, and it was a ** annoyance.

As soon as the tunnel collapses, it is impossible for the car to continue on the highway, either return to the previous highway exit and take the national highway instead, or abandon the car and walk on foot, go around to the opposite side of the tunnel, and then walk back to the highway again, but then you can only walk forward.

Zhou Yunfeng was worried, discussed with Lu Xing, and decided on the choice in the future.

"My suggestion is to abandon the car and walk around, taking the national highway is too risky, and the road conditions are not clear at high speed, even if you have to walk back later, the speed is very slow, but it is much safer." For the current situation, Lu Xing insisted on abandoning the car and making a detour.

Zhou Yunfeng thought about it, but he still put safety first, and also agreed to abandon the car and detour: "Forget it, abandon the car!" It's a pity that so many things can't be taken away......"

The Humvee was loaded with a large amount of supplies, and once the vehicle was abandoned, they could only take a small part of it, and many things could not be taken away at all, so they had to stay in the car.

After deciding to abandon the car and take a detour, the two carefully selected some things, chose as many essential things as possible, and tried to choose foods that were small in size and high in calories, and not easy to spoil.

Eventually, each of them carried a large backpack with a bulging backpack and a trolley each. The contents of the entire off-road vehicle were taken away with less than a fifth.

"It's a pity, I only drank a few sips of the few bottles of good wine I just got, and now I have to throw them away!" Before leaving, Zhou Yunfeng glanced at the car and sighed helplessly.

The two of them spent a little effort, turned over the shoulder of the highway, and walked to a small mountain road next to it, the path was narrow, the road surface was uneven, and the towbarrow was moving very slowly, and it was more difficult to walk, which was very different from when they drove before.

The total length of the tunnel is 2.5 kilometers, and it will definitely not be fast to walk on the curved path, and it will take two or three hours to get back on the highway around the tunnel.

Now it was no more limited than before, with only about two hundred visibility, and they moved very carefully and slowly.

The trail is frighteningly quiet, this kind of place is usually indispensable for the sound of insects, but now it is unusually quiet, and a large number of plants have long since died next to the highway where the vegetation is dense, leaving only bare branches, giving people a terrifying atmosphere.

Three months of extremely cold weather, followed by three months of high temperatures, led to the death of a large number of plants around the world, of course, some are still alive, Zhou Feng believes in the laws of nature, whether it is human, plants and animals, will adapt and evolve in the new environment, of course, many have been ruthlessly eliminated.

After walking for more than an hour, Zhou Yunfeng picked up the night vision binoculars in his hand, looked at the situation ahead, and found that there were several houses about seven or eight hundred meters away, and then stopped and said to Lu Xing: "There are a few houses in front, it is estimated that there were originally people living there, and there may be polluters over there." ”

When Lu Xing heard this, he also picked up the binoculars in his hand and looked at them a few times: "Where is the only way to go, there are only a few households, even if there are polluters, there should not be many, be careful when you get closer!" ”

Zhou Yunfeng nodded, continued to move forward, and when they were about a hundred meters away from several houses, the two of them stopped, put the trolley here temporarily, went to the front together to check the situation, and came back to pick up things after confirming that it was safe.

The two of them had a military crossbow in their hands, and they had already loaded their crossbow arrows and were ready to be fired, wearing helmets and a barrel of arrows hanging from their waists, and they moved forward little by little.

After a while, the two were only about ten meters away from the first building, and soon, they passed in front of the first house, and did not find the polluter, so they continued to walk forward.

As they passed by the third house, a pair of blood-red eyes spotted the two of them in a dead corner next to the house......
