[Conan] He is always on the front line of seeking death.

Chapter 29 How can a researcher be called that?

Ah...where's the snow?

Wang Ziyu looked at the trees with green buds outside, feeling a little confused.

Since the last gathering of magic enthusiasts, Wang Tianyu had a good sleep from noon to the next morning.

Then as soon as I got up, the snow was gone. Apparently we had a snowball fight yesterday...

It is indeed the time-chaotic world of Kexue.

Wang Ziyu continued to improve his weapons.

During this period, Wang Ziyu tried to drink some tea again, jumped repeatedly between Wang Tianyu and Wang Ziyu, and came to some conclusions.

It hurts when it gets bigger or smaller! It hurts so much!

There will also be a two-minute period of weakness.

After the first time after shrinking, drinking a full cup of tea can maintain the adult form for eight hours. Now the same amount can only maintain the adult form for two hours. Drinking another cup of tea at almost two hours can maintain the adult form for two hours or drinking it directly. Double the amount and keep for 4 hours.

But it must be made with hot water. It doesn't matter if it's cold, but cold water is useless for making tea.

And the longer it takes to get bigger, the more intense the pain will be when it gets smaller.

The maximum limit for staying awake is 12 hours.

If it takes more than 12 hours, you will be in coma. The more tea you sing, the weakness time will increase exponentially, reaching a 12-minute weakness period at 64 hours.

It's only been an hour...

If the weak period is longer, it will be very dangerous, or it will remain in the form of an adult, fall asleep and turn into a child when reaching a safe place, and spend the weak period. Or don't transform into an adult form.

Wang Ziyu came back to reality with his chin on his hand and stared at the drawings on the table with an unhappy expression.

Sight……

Scopes are mainly divided into three categories: telescopic sights, collimating sights, and reflective sights.

Telescopic sight has a magnifying effect and can see and identify distant targets clearly, and is suitable for precise shooting at long distances. Because it is often used for sniping, it is often called a sniperscope.

The optical system of the telescopic sight still uses the Kepler telescopic system with an image rotation system. The basic structure is composed of an objective lens, an inverted image lens (converter lens) and an eyepiece, plus a reticle. There are aiming marks on the reticle, and you can aim at targets at different distances by moving the reticle or using reticles in different positions. Some scopes also have a zoom function, using a lower magnification to search for and aim at close targets, and a higher magnification to shoot at distant targets.

Crosshairs are the most common reticle for this type of sight, and early sights only had this set of crosshairs. Later, manufacturers added reticles for measuring range and angle on the reticle. The principle is very simple. The distance is estimated by comparing the height (or width) of the reticle mark with the reference object.

dense site reticle

Mildot reticle is the most popular reticle for sniper scopes nowadays. The marking of dense sites looks very simple, just marking the small black dots on the cross lines. On the Leupold M310x scope, there is a density between every two adjacent black dots. However, the mil-dot sight is not easy to use and requires rigorous training, but the measured values are quite accurate. The slide rule is a dense point slide rule, which can help you learn to use the dense point measurement method, but it is only used for learning, because under actual combat conditions, snipers are not allowed to use the slide rule to measure target distances.

collimating optical sight

It appeared in the 20s and was used in small quantities on the Vietnam battlefield. It began to develop in the early 70s. Collimating sights are not accurate when dealing with long-distance targets, but in close combat, especially when shooting moving targets, their response speed and accuracy are significantly better than other sights, so they are mainly used as close combat sights. However, after better reflective sights appeared, collimated sights began to decline. But because this sighting device is much cheaper than a reflex sight, it has not been completely withdrawn from the market yet.

This kind of sight has a light guide rod at the front, which is illuminated by natural light or other light sources from the side. The rear end surface of the light guide rod is close to an aperture hole, which limits the normal range and light shape. When one eye looks into the scope, it will see the image of the aperture hole at infinity - a red dot. When the other eye aims at the target, according to the physiological function of combining the target images of both eyes into one according to the principle of human vision, a red bright spot will be produced to suppress the target. As long as the aiming line of the sight is consistent with the aiming baseline of the gun, the function of binocular aiming and shooting is achieved.

But Wang Ziyu is rich, so he doesn't use collimating sights very much, and the accuracy is not enough.

Reflex sight

Although it is also called a "sight", its principle is different from that of a telescopic sight. Its optical system is relatively simple and usually does not have a magnification system, so there is no inverted image system. This type of sight also has another name - red dot sight, because the aiming mark of this type of sight is usually a red or bright orange light dot. Of course, not all reflex sights use light. Some of them will be crosshairs, halos or even other shapes.

For a spectroscope with good accuracy, the aiming line is always parallel to the axis of the sight. No matter where the light reflection point of the aiming mark is, it is always at the point of impact.

For spectroscopes with poor accuracy, when the line of sight deviates from the axis of the scope, the aiming mark will deviate from the impact point.

Due to the above advantages, the reflective principle allows the eyes to not be aligned with the axis of the scope when aiming, so the aiming response is faster than using the light guide principle. This makes dot sights based on the reflex principle very popular. After entering the 1990s, armies of various countries began to attach importance to the tactical value of this scope and equipped a large number of troops.

Reflective dot sights usually have two structures, one is barrel type and the other is window type. The window structure is relatively simple, but the spectroscope is completely exposed; the barrel structure looks very similar to a telescopic sight. The spectroscope is wrapped in the barrel body, and is protected by the objective lens and eyepiece at the front and rear. There are now some products that combine dot sights and telescopic sights, that is, dot sights with a magnifying function.

Wang Ziyu himself prefers telescopic sights

Although snipers are not allowed to use a slide rule to measure the target distance under actual combat conditions, Wang Ziyu does not need to go directly to the battlefield. It is the easiest option to eliminate the enemy outside the range of the enemy. This way, it can be concealed quickly and quickly. leave.

The advantage of this type of sight is that it is accurate, but it will be affected by gusts of wind.

The technical term is gust, which refers to a sudden change in wind speed. And when shooting targets the size of human-sized targets, if the wind speed suddenly changes at a distance of more than 800 yards, there is a high chance that the bullet will be blown away.

Therefore, Wang Ziyu especially likes to do tasks when there is no wind or low wind.

As for the reflective sight, it is more suitable for use in closer situations, because it no longer needs to be aligned with the axis of the sight, which saves time. It is most suitable when life and death can be decided in a few tenths of a second.

Wang Ziyu immersed himself in hard work. This era is really backward! ! !

However, development will be very fast in the future, especially this year, even in an anime, we must keep up with the trend of the times, and we must not be abandoned!

At this time, Gu Jing went upstairs to ask Wang Ziyu to eat, and saw Wang Ziyu assembling lenses with a serious face.

We're improving our equipment again, it's really cool.

Gu Jing felt a little emotional, he was indeed the person that every major organization wanted.

Gu Jing put the hot milk on the table and said

"Take a rest and go to the beach?"

"Where are you going?" Wang Ziyu drank the milk and put it on the edge of the table. He turned his head and leaned on the back of the chair, looking at Gu Jing expressionlessly, with boredom in his eyes.

Wang Ziyu sighed, he was almost moldy...

Gu Jing walked around Wang Ziyu, lying casually on the bed with his eyes closed, smiling and saying expectantly

"Let's go to Izu Peninsula. There will also be a fireworks display in Izu at this time."

Izu’s Maritime Fireworks Festival...

Wang Ziyu leaned on the table and leaned his chin, thinking about what it would look like.

She must be very beautiful. Wang Ziyu couldn't think of a picture that was too detailed. While Gu Jing was lying on the bed, she secretly opened Weibo and searched...

Japan’s summer fireworks festival...

The original summer fireworks festival was a consolation ceremony to commemorate the souls of the dead.

It began with Tokugawa Yoshimune, the eighth shogun of the Tokugawa shogunate in the Edo period. In 1732, plague and fires spread frequently in Edo. The shogunate set off fireworks on the banks of the Sumida River in Tokyo to hold a ceremony for the water god to drive away evil spirits.

There are some attractions:

Niigata Prefecture Nagaoka Festival Fireworks Display: Japan’s largest fireworks display.

Nagaoka City is a famous fireworks kingdom. The Nagaoka Festival in early August every year holds one of the "Three Major Fireworks Displays in Japan" - the Phoenix Revival Prayer Fireworks Display, which has over a million people attending.

For example, the fireworks display in Nagaoka is held every year at 8:1 pm on August 10st, and the official fireworks display is held in the next two days.

Akita Prefecture Omagari National Fireworks Competition: The most artistic and ornamental fireworks display

Ise Shrine in Mie Prefecture hosts the National Fireworks Festival: one of the three major competitive fireworks festivals

Ibaraki Prefecture Furukawa Fireworks Festival: One of the largest fireworks displays in the Kanto region

Kumano Fireworks Festival in Mie Prefecture: The summer fireworks festival in the Kumano area, a world heritage site, is a stunning sight with a 600-meter-diameter three-foot-tall jade blooming in the sea.

However, fireworks were only set off during a certain period of time, and they were mostly in Xiatian.

Generally speaking, firework festivals are held in the summer, but the special feature of the Izu Fireworks Festival is that they are held all year round, and they are set off at sea! There are venues in Atami, Ito, Atagawa, Izuyama, Toi, etc.!

There is also a firefly festival in mid-June!

There was once a cartoon called Forest of Fireflies, which made many people cry. Throughout June, the entire Mount Amagi in Izu will turn into a forest of fireflies like this. You can choose a hot spring hotel where you can watch fireflies. It’s the ultimate romance on a summer night.

The corner of Wang Ziyu's mouth twitched. How could there be any romance between two big men? The only woman still has a boyfriend...

Forget it, let’s catch fireflies then. Wang Ziyu continued to look down.

Japan, like China, has the custom of setting off fireworks. In Japanese anime, the girls put on bright yukatas and go to festivals with their sweethearts to watch fireworks. I wonder how many people still remember this?

What a pretty girl...

Wang Ziyu tapped his chin twice with the hand holding his chin, thinking.

Will I get a girlfriend by then? I'm a little nervous, but also a little hopeful...

"Shall we take a car or drive then?"

Wang Ziyu was still looking forward to it and didn't notice what Gu Jing said.

Gu Jing didn't hear the answer and opened his eyes to see a blushing Wang Ziyu.

He still looks like a child now, very cute.

But when Wang Ziyu assumed the form of an adult, Gu Jing felt a little uncomfortable when he thought of Wang Ziyu being with another woman. He wanted to go over and pinch his face to make him sober up.

That's what he thought and did.

At this moment, Wang Ziyu had just recovered from his imagination when he felt his face being pinched...

The frightened Wang Ziyu jumped out, her face red, like a young boy who was discovered by his teacher when he fell in love early...

Then both of them paused

Gu Jing suddenly wanted to play and suddenly said

"Ayu, your face is very soft."

???

Wang Ziyu looked at Gu Jing in confusion.

What the hell is soft...

Wang Ziyu wanted to say something but couldn't. Looking at Gu Jing's retracted hand and that deliberate smile...

Wang Ziyu "..."

Play with me, right...

Wang Ziyu closed his eyes, opened them and stared at Gu Jing, as if he was aiming for prey. He jumped onto the stool and overturned the stool, knocking the slightly dazed Gu Jing onto the bed.

Two arms were pressed on both sides of Gu Jing's face. At this time, the sunlight outside the window was obscured by clouds, casting a shadow on Wang Ziyu's face, making it difficult to see his expression clearly.

The two of them maintained this posture, and the sound of leaves and wind outside seemed to be silent.

Time seemed to have frozen, as if a long time had passed, but also as if it was only a few seconds.

Wang Ziyu raised one hand, pinched Gu Jing's chin and lifted it up. With a sinister smile, he released a domineering aura and said a sentence he had heard before.

"Oh, Jingguang, you successfully caught my attention."

Gu Jing's pupils shrank slightly, and even though his heart was filled with turmoil, he still said calmly.

"You remember?"

"Yes, little policeman."

Wang Ziyu continued with a fake smile.

"You even tricked me into a mission, you guys are really good at it!"

Zhu Fu Jingguang also remembered the previous incident

Wang Ziyu couldn't bear it any longer, and instantly stretched out his evil claws towards Jing Guang like a hungry tiger pouncing on food!

Zhu Fu Jingguang felt a little emotional. At that time, Wang Ziyu was still a bit innocent, serious and fun-loving, with a hint of arrogance...

Zhu Fu Jingguang smiled and grabbed Wang Ziyu's hand holding his face in two or three moves.

"You're still laughing!" Wang Ziyu was a little angry and said loudly

If I hadn't become smaller, you would be the one caught now!

"Okay, okay, no more playing." Jing Guang grabbed Wang Ziyu's hand and said with a smile.

"Then let go."

"Not loose."

Wang Zi angrily kicked Jing Guang's armpit and scratched him twice.

Wang Ziyu clearly felt Jing Guang dodge slightly.

Zhu Fu Jingguang held back his smile and said, "Aren't you tired from holding your legs like this?"

"Are you letting go?" Wang Ziyu threatened Jingguang with a smile, staring closely at Jingguang's face.

It seems that he hasn't gotten angry yet and hasn't exerted much force yet.

Jing Guang thought in his mind and sat up, grabbed Wang Ziyu's two hands with one hand and lifted them up.

Then both of them froze.

Jing Guang tilted his head slightly and saw the pale-faced Wang Ziyu...

Just now, Wang Ziyu's foot slipped and got stuck on Gu Jing's shoulder, and his other foot got stuck on the other side of Jing Guang's waist, and then he was forced to do the splits and press that piece again...

"It hurts..."

Wang Ziyu's eyes were a little dark, and he turned around and leaned back without speaking.

Jingguang was shocked and quickly put Wang Ziyu down, and then...

He was kicked angrily by Wang Ziyu who suddenly came to his senses...

Zhu Fu Jingguang "..."

Wang Ziyu "haha"

Let you also feel this feeling

Hiss - it hurts

The moment I kicked Jingguang just now, I stretched that area again.

Around noon, Miyano Akemi opened the door and said

"It's time to eat..., what's wrong with you?"

Jing Guang and Wang Ziyu lay hunched on the bed, not wanting to move.
