The parts of the firearms were steamed in boiling water and reassembled, and they were all Type 53 rifles, 7.62 mm caliber, a total of thirteen.

These low-performance ancient guns were imitations of the Mosin-Nagant M44 rifles of the former Soviet Union, which were used by the Chinese troops at that time.

Therefore, from the structure of weapons and nuclear bomb parts in the underground warehouses of the nuclear test base, it can be seen that China did strictly implement the treaty at that time.

Lifus chopped down a few small trees with a wood-splitting axe, made some rifle butts out of the trunks, and then sharpened them with a dagger from Li Xinran, and coated them with clear oil.

A total of five guns were fitted with butts, and Li Xinran held one of the guns and kept rubbing them, a little bit in love, which looked much more imposing than the pistol left by her father, although the performance was much worse.

Lin Xuexi also took one, the era before she traveled was only a century away from when these weapons ruled the world, so she didn't feel that these firearms were particularly outdated.

"Can you teach me how to shoot?" Lin Xuexi said to Lifus.

Lifus was a little embarrassed, as Lin Xuexi's suitor, of course he wished to have such an opportunity to have face-to-face and hand-to-hand intimate contact with her, but Lifus didn't know where to start at all.

Lifus didn't learn to shoot, but he was a sharpshooter by nature, and he didn't even have to aim because of the photon template in his eye.

He had never used a live-fire weapon with such poor performance, the caliber was too large, the muzzle velocity of the bullet was too slow, the range was too close, the recoil was too strong, it could not be fired in bursts, and it required a lot of calculations.

But he still agreed, just because of the eagerness and expectation in Lin Xuexi's eyes.

Bang!

Lifus fired a shot into the sky, and there was still some residual oil in the barrel, and black smoke came out.

"The initial velocity of the bullet is 795 meters per second, and the speed outside 100 meters is 750 meters per second, while the reaction time of a normal person is about 0.3 seconds, regardless of the deviation caused by the wind direction and wind speed, as well as the frictional resistance of the air, that is to say, if you want to achieve 100 shots, you must ensure that the target is within 300 meters."

Li Fusi shook his head, the performance of the Type 53 rifle gun was not as good as Li Xinran's 3 mm caliber pistol, but unfortunately that pistol only had seven bullets left.

Lin Xuexi wore a black blindfold on his right eye, tied to his head with a soft string, and a cloth clip wrapped around his waist, with dense bullets inserted on it, and the brilliant brass bullet casings were next to each other, making Lin Xuexi look like a female bandit who was the king of the mountain.

She took great pains to sew bullet belts, and sewed one for both Fortunes and Grace, and she had a passion for shooting.

"Can you do it in 300 meters?" Lin Xuexi felt that Li Fusi must be able to do it himself, but she still expressed her doubts, she never thought that there was such a thing as a hundred shots in this world.

Lifus didn't speak, he took ten Guanyin fruit shells and threw them casually on the snow, then walked backwards about five hundred meters, turned around and shot, and didn't even make the action of aiming.

Bang! Bang! Bang! Bang! Bang!

The sound of gunfire echoed through the silent forest, and the snow on the trees was shaken.

Lifus replaced the magazine with bullets, but still didn't aim.

Bang! Bang! Bang! Bang! Bang!

The gunfire finally stopped, Lin Xuexi and Li Xinran stood not far from the fruit shell, watching Li Fusi walk to a place that was almost impossible to see, and then heard the sound of the bullet rubbing the air, and with a "chirp", the fruit shell at the front disappeared and was shattered.

Then the second, the third......

Lifus came back from a distance with a gun in his hand, and the expression on his face was serious, changing from his usual casual and non-slippery.

"If there were no strong wind and magnetic field interference, there would be no difference between three meters and three kilometers of shooting at a target that doesn't move." Lifus seems to want to be a good shooting teacher, and he has become the clever and experienced agent again, not Lin Xuexi's little fan brother.

"But we don't have a scope at all, how did you do that?" Lin Xuexi thought this was incredible.

"From the moment the warhead is discharged, the drag force of the air and the gravitational pull of the earth, as well as the direction of rotation and rotation of the warhead, all determine that its flight trajectory cannot be a symmetrical parabola, but the gradual decrease of its speed and altitude on the time axis is still a simple linear function, so if we regard the position of the bullet loading and the muzzle as two points or a line segment, then the landing point of the warhead can be easily calculated." Lifus explained, in front of Lin Xuexi, he seemed to always be patient.

"Can we be like you, then? After passing the training? Lin Xuexi asked.

"Unfortunately, no." Lifus directly denied. "But if you are diligent enough, you can also achieve a very high hit rate in a short time, if it is not a long-distance sniper, the scope is not particularly important, especially within three hundred meters, this kind of distance that does not need to be predicted, as long as the target is within the field of vision, there is a considerable hit rate, and the machine sight within seventy meters will be more reliable than using the scope."

"All you need to do is keep practicing, repetitively practicing, and the muscle memory base is getting bigger and bigger, and the hit rate is getting higher and higher."

"Practice is actually a scientific experiment, with countless failures in exchange for the right experience, and during the process, you have to constantly sift through and verify to find a way to succeed."

Li Fusi drew a few target positions with lime outside the wall, and watched Lin Xuexi and Li Xinran practice shooting from the side.

"Aren't you going to instruct us?" Li Xinran was angry at Lifus's inaction.

"To be honest, I haven't learned to shoot either, so I'm not qualified to instruct you at all, but I think it should be quite simple, just adjust the rhythm of your breathing, keep your arms steady, and concentrate. In fact, no matter what you do, you must be attentive, concentration may not make you better, but not attentive will definitely make you do worse. ”

Li Xinran's shooting speed was very slow, and the loud sound and recoil of the old-fashioned firearm made her want to give up, but seeing that Lin Xuexi was still practicing, she persevered.

The two of them stood fifty meters away from the target position to shoot, and their accuracy was miserable at first, but then Lin Xuexi seemed to have mastered the trick, and often could hit the results of eight rings and nine rings, and most of them were within the five rings, never missing the target.

"Don't play, don't play, it's really infuriating!" Li Xinran threw the gun on the ground, a little discouraged, she couldn't figure out why Lin Xuexi learned so quickly, was it because she was more talented than herself?

"Alright, that's all for today, let's go back and cook." Lifus suggested.

"You guys go back first, I'll practice for a while." Lin Xuexi said that her shoulder had been swollen by the butt of the gun, but she still wanted to hold on a little longer.

"Well, you shouldn't practice too late." Li Fusi nodded at Lin Xuexi, he knew that Lin Xuexi seemed weak, but he was actually very stubborn and stubborn in his heart.

In the next few days, Lin Xuexi seemed to be obsessed with shooting, practicing every day, and now she can hit the bull's-eye with one shot from a distance of one hundred and fifty meters, even Lifus has to admire, such super perseverance, such an amazing talent.

After a symbolic dinner, Lifus returned to the underground warehouse, where he lay down in the bed and carved something with a dagger under the light of the monkey watch.

Since opening the underground warehouse, he has moved here to sleep, and although both girls don't mind and offer to keep him, and he has absolute confidence in his control, he still insists on moving over, because it can at least make him look "gentleman".

That's right, gentleman.

It's a very pedantic word, but it's especially chivalrous in this cruel last days.

I don't know if I've read too many ancient books recently, and Lifus feels that his thoughts are also a bit "atavistic".

It was cold in the warehouse, but not damp, and Lifus was carving a beautiful wooden comb to give to Lin Xuexi tomorrow.

The wooden comb was carved from the roots of the cedar and was very hard, and Lifus had been carving it for several days, and was now about to finish it.

There are four small characters engraved on both sides of the wooden comb, one side is engraved with "Magnificent Posture", and the other side is engraved with "Kuangshi Xiuqun".

This is a phrase in Tao Yuanming's "Leisure Fu", which is used to describe the beauty of women. Li Fusi originally wanted to engrave Wen Tingyun's "The hills overlap the golden light, and the temples and clouds want to be fragrant and snowy", but the comb is too small to engrave, and these two sentences are a bit vulgar.

Li Fusi summoned a little Yuan Qi energy in his body and acted on his fingers, and the roots of the Han fir tree, which were originally as hard as iron, became like tofu under his knife. After more than ten days of practice, he now does not have to stick to the posture at all when running the exercises in the Tao Sutra, not only does he not have to meditate, but he can even run as he wishes in any situation.

Another reason why Lifus decided to move to the underground warehouse was to study the exercises. Since the first night he moved here, he had done an experiment on the body's absorption of radiation during exercise.

In the end, he found that as he had guessed, he sat next to the nuclear filling of the atomic bomb and worked all night, that is, the cylindrical weapon-grade uranium block with a uranium-235 concentration of more than 93%, not only the rays released were absorbed by Lifus, but also the radioactivity itself, and the uranium block that lost its radioactivity was like an ordinary piece of metal, its atomic number has not changed, the mass is still very large, and it has a certain toxicity, but it really no longer emits any radiation, alpha rays, beta rays, Gamma rays, all gone.

The half-life of uranium-235 is 700 million years, and it is hard to imagine that it takes so long to decay off half of the energy of such a large block of highly enriched uranium, which can be absorbed by Lifers overnight, and if these uranium-235 are completely fissioned, they can level a city.

And after he absorbed these energies, he felt that the Yuan Qi energy in his body had increased by about one thousandth, and it seemed that the compression density of these Yuan Qi energies was really terrifying, comparable to gamma ray bursts.

The lump of uranium that no longer emitted radiation, Lifs felt that it had run out of energy, and even if it bombarded it with neutrons now, it might not fission again.

During this period, Lifus also discovered an interesting phenomenon, he exercised in places where the concentration of external radiation was very small, and the energy absorbed seemed to come from the air, but the growth rate of Yuan Qi energy in his body was extremely slow.

Li Fusi calculated that the amount of Yuan Qi energy absorbed by practicing for one hour in a place with a high radiation concentration in the warehouse would take four months to barely complete in the outside air.

"Is it true that the smaller the particles, the better they are absorbed? And the more energy? Lifs thought so, thinking that it was probably so, because according to his previous conjecture, he needed to convert the Higgs boson into Yuanqi particles, and the smaller the particles, the closer they were to the essence of matter, which is why atomic bombs are more powerful than ordinary bombs, and hydrogen bombs are more powerful than atomic bombs, and particle bombs are more powerful than hydrogen bombs.

Now just absorbing the energy of uranium-235 can convert a large amount of Yuan Qi energy, so what about atoms that are lighter than uranium? Uranium is very low in atomic number, in the ninety-second position, what if it is hydrogen, which comes first?

Lifus thought of the isotopes of hydrogen deuterium and tritium for fusion fusion, which should be easier to absorb and more energetic, right?

He was eager to find a heavy hydrogen plant to test his guesses, and if the results were correct, he estimated that he could probably draw energy from particle cells and particle reactors, or even absorb electricity directly.

What will you become in the end?

Could it be that science and metaphysics have the same end? Or is there no science or metaphysics in this world, but in fact it is all natural science?

Liphes remembered Harari's famous quote: "History begins when man creates God and ends when man becomes God." ”
