now chose a simple proportional series of questions, but he was regarded by the other side as the end of a crane with poor learning.her self-esteem can't even pass this level!just when Wang Yun wante...countdown to 144 00.

12:00 midnight, in the dark.

when Li Tongyi saw that the chat was coming to an end, he quickly crept out of the toilet and crept to the living room.

now that Grandma and Grandpa are here, this small house with two bedrooms and one living room, Xiao Tongyi's bedroom is for them to live in, and she has to sleep in one bedroom with her mother.

this is very inconvenient.

so tonight, when Qingchen told her in advance that she was going to have a chat group, Xiao Tongyi suggested to sleep on the living room sofa.

Jiang Xue was a little strange when she heard this proposal in the evening. After all, the little girl usually slept with her mother. Why did she suddenly change her temper today

Li Tongyi's explanation is: today, she heard that all the classmates in the class had fallen asleep by themselves, and she could not be worse than the other children.

when she heard this, Jiang Xue felt relieved that her daughter had finally grown up.

but I guess she didn't expect that her daughter grew up seven years old overnight.

and became sisters with her.

just as Li Tongyi was lying on the sofa, he suddenly found that the light in the living room was turned on.

Jiang Xue stood at the door of his bedroom and said strangely, "Why did you go to the toilet for so long"

Li Tongyi said hurriedly, "Mom, there's something wrong with my stomach."

Jiang Xue was stupefied for a moment: "I told you not to eat so much at night. It must have accumulated food."

as she took the stomach-strengthening tablets and handed them to Li Tongyi, the little girl said, "Grandma's cooking is so good."

"wait," Jiang Xue asked, "you didn't hide in the toilet and play with your cell phone, did you Show me your phone. "

Li Tongyi cleverly handed the phone over: "I really didn't play with the phone."

Jiang Xue unlocked the little girl's password, but she didn't find anything for a long time, so she was relieved: "do you want to sleep with your mother"

"No," Li Tongyi said cleverly, "Grandma and Grandpa are going back to Zhengcheng tomorrow, and it's not a bad day."

"well, then go to bed early," Jiang Xue said, tucking her in.

Li Tongyi breathed a sigh of relief as she watched Jiang Xue return to her room. Luckily, her phone had two interfaces, otherwise Jiang Xue would have seen her chatting just now.

sure enough, you have to be as careful as brother Qingchen at all times, or you will be beaten.

Li Tongyi recalled what he had done tonight and estimated that if he was beaten, he would not be too light.

however, she thinks it's dangerous but interesting to play like this.

stimulation.

at the same time, Qingchen went to the seedling room to have a look, and the demon stamp holder Mianyu did not send a new letter.

he went back to his bedroom and began to practice sniping without moving.

in the mysterious world of moral persuasion, when Qing Dust moves the target to 800m, the trajectory begins to show a slight parabola.

he has studied known actual combat cases on the Internet, the most typical of which is Operation Anaconda, in which a sniper used a sniper rifle and equipped with a 16x optical scope to kill a terrorist with three shots at a distance of 2430 meters.

the first shot failed, the second shot hit the terrorist's backpack, and it was not until the third shot that he finally succeeded.

at that time, the sniper was at a high altitude of 3000 meters, the air was thin, and the effect of air resistance was small.

even so, the highest drop of the parabola hit by the bullet reached a vertical height of 20 meters.

the calculation of the parabola with a huge drop is one of the important factors restricting most snipers from hitting targets 1500 meters away.

(adsbygoogle = indo.adsbygoogle | | []). Ush ({});

if you can see the bullet trajectory of the sniper rifle, it will be more like a shell, long-range for more than two seconds, and finally fall to the ground in a parabola.

after Qingchen broke away from the mysterious world, he asked: "when the distance is more than 2000 meters, is the effective killing by virtue enough to kill people"

"if you shoot at a distance of more than 2000 meters, you may not be able to penetrate a hard bone, so you must hit the eye socket," he said. "otherwise, why do you think the target only has one coin"

Qingchen was stupefied for a moment. He also said earlier that the training of snipers is not so harsh. They are all humanoid targets.

200m, 400m toothpick, coin is OK, more than 2000 meters coin, sounds like a myth.

it turns out that the target shooting training in the mysterious world is for the extraordinary, to hit the eye socket.

Qingchen thought to himself, can he really do it Maybe, but he has to devote more time to training.

and this is because most snipers' optical sights allow a tolerance of 0.28cm, that is, the sight deviates 42cm from the target at 1500 meters.

this is because it is difficult to guarantee zero error in the production process.

therefore, the sniper needs to adjust his own alignment during shooting to eliminate this 42 cm error.

but there is no need to convince people with virtue, it is a contraindication under the rules, and itself is an absolutely perfect anti-equipment sniper rifle.

when the trajectory appears parabola, the training progress of Qingchen is obviously reduced.

it took him all night to push the target to a distance of 800m.

this is the standard for the use of 7.62mm sniper rifles in the army. In other words, Qingchen is finally a qualified sniper, but not the god of snipers.

however, 800m is sufficient for use in cities, except in a specific sniper environment.

"enough for the time being." Qingchen races against the clock to train to make himself have the ability to kill in a long distance.

now, no matter what happens, Magic Feather must die even if it is a control-level time walker within 800m.

what's more, the other party may not be able to control the master.

Qingchen calculated that he had previously estimated that he would be able to master the effective range of 2600 meters in seven days, but he still overestimated himself and underestimated the difficulty.

at present, it will take at least 12 days, and this is just a calculation of wind speed.

when he completes his wind speed training, he will have to train at different altitudes.

this is a long-term training program.

rise abruptly based on accumulated strength.

at the end of the training, Yi suddenly said, "are you going to train Hu calves" I suggest you buy Chen's oral medicine from the black market in the world. The price is not as expensive as genetic medicine. It is mainly used to balance and increase muscle and cardiopulmonary function. One side effect of this thing is sweating after taking it. However, long-term clinical evidence shows that there are no other sequelae. In the Federal Army, ambitious soldiers who have not yet been selected as genetic warriors will secretly buy and take them, which will probably help ordinary people quickly rise to the tipping point of 2.999. "

Qingchen said after careful consideration: "it is not yet time for people to take medicine. What Hu Xiaoniu and others need to improve most is not their physical fitness, but their mental will."

perseverance and indomitable will are what the chivalry road needs most.

this will can only be exercised in the face of absolute adversity.

thought about it and said, "I quite agree with you. My mother, Yang Xiaoqing, once said: when disaster strikes, the spiritual will is the first sequence of weapons for human beings to face danger."unication channel. "Don't be too cold to make this place look lively."just at this time, the famous host saw that the venue was really not warm, so he simply said, "it seems that everyone is here for...
