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

It's seven o'clock

There is still an hour left before the start

Three people were wandering in the street,

As we walked along the street, more and more people came and went on the street. They were all men, women, old people and children wearing bathrobes and strolling leisurely.

There are countless dazzling food stalls in the night market

Octopus balls, grilled squid, taiyaki, oden, apple candy...

The three people continued walking to the venue,

As night falls, the fireworks display begins.

Fireworks flew into the sky one after another, exploding into brilliant light and disappearing in an instant.

Wang Ziyu stood on the street, holding shaved ice and watching the fireworks blooming in the sky. It felt good, but there were people around, and it was a bit crowded...

Then two people didn't notice Wang Ziyu. The boy who was happily talking to his girlfriend accidentally bumped into Wang Ziyu who was watching the fireworks.

Maybe because they talked about a key issue, the boy got a little excited, and then he got a little too strong and knocked Wang Ziyu staggering.

Wang Ziyu held the shaved ice in his hands and turned his head after finally steadying himself. A couple appeared behind him. They were feeding each other octopus balls just now.

Because the hand was frozen in mid-air.

Then the two of them squatted down together, looked at Wang Ziyu's level, and said

"Little brother, are you okay?" the two people said nervously.

Wang Ziyu "..."

I'm fine, really.

Then after the two people left, Wang Ziyu dug out a piece of cold blue ice with a spoon with a spoon, with blueberry jam and white condensed milk on it, and stuffed it into his mouth.

It's very sweet, and the coolness spreads in your mouth instantly, and the heat completely disappears.

This is the fun and refreshing summer!

Well, snacks are better,

Dog food is free...

Wang Ziyu squinted his eyes slightly, chewed, and then dug out another piece.

"Eat slowly, don't get upset."

Even at this time, Jing Guang still reminds himself not to eat too much...

Aren't you two eating too...

Jingguang and Mingmei bought smoothies, one with strawberry flavor and one with red bean paste.

"Mom! I caught a goldfish!"

An excited child's voice sounded from the right.

The three of them turned to look over, then lowered their heads at the same time and asked Wang Ziyu, "Xiao Tianyu, are you going to catch goldfish?"

Wang Ziyu was a little speechless. I'm not really a child. Just now he wanted to ask Mingmei if she wanted to go fishing...

"No, you won't be able to feed them after you catch them, and the stall owner might not even be able to feed them." Wang Ziyu sighed and continued.

"You two go ahead and make a profit. I can make a lot every time. I'm afraid the store manager will blame me. If you two lose too much, I will help you get back your money! I'll go for a walk."

"You two, want to catch goldfish? A net costs 100 yen, which is not expensive at all." The shop owner said with a smile.

"Then let's go to the six Internet cafes first."

Jingguang said, putting the smoothie aside, taking out his wallet and paying the boss.

Then Miyano Akemi saw Wang Ziyu pick up a piece of Jingguang's strawberry smoothie while Jingguang was not paying attention, throw it into his mouth accurately, and then sneak away.

He also put his finger up to his lips to signal himself not to speak...

Miyano Akemi said she knew and pretended not to see it.

Then Zhu Fu Jingguang turned around and saw an obviously missing piece of smoothie and the missing Wang Ziyu.

Zhu Fu Jingguang "..."

Good guy!

Five minutes later, Morofushi Kagemitsu and Miyano Akemi were squatting in front of the red stall, staring at the fish in the goldfish tank. Both of them were a little bored.

To be precise, both of them had something on their minds. Looking at the fireworks in the sky, the two of them recalled the past.

Miyano Akemi dug out her old cell phone and looked at the chat history with the Maharaja.

He thought that Morohoshi was old and hadn't seen him in three years, but he was still pretending to be dead, so it was best not to contact him.

However, Ayu checked her phone thoroughly and canceled the original account. She could receive the message, but to outsiders, it always seemed like she had not received it. I am living a good life these days, Maharaja... how about you.

How was your life after learning of my "death"...

Zhufu Jingguang also recalled a lot, including some interesting things in the police academy, doing missions with Zero, and hiding the identity of Miyano Akemi's lover Ran with Wang Ziyu...

Ayu, what are you thinking about?

There was a pile of torn paper nets at his feet, and there was a boss with a dark face next to him.

Then there were eight small goldfish in the small fish tank (that Mingmei bought), red, black, gold, and flower.

The children next to me were almost crying. The big brother almost took away all the beautiful fish, but there were still some left.

The child was trying hard to catch the goldfish, but suddenly the paper net broke...

Child"……"

At this time, Wang Ziyu bought a box of octopus balls by himself and ate them while walking on the road.

His mentality was a bit explosive. Along the way, he heard

"Wow, this kid is so cute!"

"I really hope I can have such a cute one!"

Wang Ziyu "..."

He'd better go back first.

As for the fireworks in the sky...

I really want to make one myself and put it in the sky! ! !

8:27

Wang Ziyu was taking a walk at this time and bought three rice balls filled with tuna salad and sweet corn kernels.

Put the rice balls in a bag, hold the bag in one hand, and hold the shaved ice in the other. He ate a little too much, and now he is a little cold...

At this time, Wang Ziyu was going to go back to the hotel alone. Just now Jingguang said that he bought a fish tank to keep the goldfish alive, so he went back first.

Wang Ziyu yawned and felt a little sleepy, walking back to the hotel.

At this time, he had just crossed the railway track across the road, and then happened to see two young men and women entering the woods.

Wang Ziyu "..."

This couple is even more outrageous!

Then Wang Ziyu took another bite of shaved ice (newly bought with lemon flavor), chewed it squeakingly, and then passed quickly, out of sight but in peace.

He seemed sore.

Before Wang Ziyu had gone far, the man among the two men raised his head and glanced at the direction Wang Ziyu left.

Wang Ziyu returned to the hotel and knocked on the door of the double room.

"it's me."

Jing Guang opened the door and looked at Wang Ziyu's hands.

Sure enough, there was no sugar left!

Speechless Jingguang passed the bag and closed the door and said, "It's not like I won't let you eat sweets..."

Wang Ziyu was changing his slippers. Hearing these words, he smiled on the outside but felt resentful in his heart.

Liar! This sentence is simply magical! ! !

Wang Ziyu had a dark face. He had a toothache due to some reasons, and then Jingguang restricted his sweets!

Too cruel! ! !

But there are no countermeasures...

Wang Ziyu leaned against the wall and smiled proudly at Jingguang, wouldn't it be over if Jingguang was put away?

Zhu Fu Jingguang "..."

I was away for a few months back then, and I haven't even settled the account with you for the piles of candies when I suddenly came home!

Jing Guang put the bag on the cabinet beside the bed and said to Wang Ziyu with a dark face and an unknown resentment today.

"Brush my teeth."

Wang Ziyu "..."

He had nothing to say about this matter.

Because Jingguang took the rice balls I sold!

When did he take it...

Wang Ziyu brushed his teeth in the mirror, feeling a little depressed.

It seemed like when I first entered the door.

Wang Ziyu washed his face and felt embarrassed. It seemed that he had given the bag to Jing Guang just now...

At this time, Jingguang looked at Wang Ziyu who seemed depressed, then looked at the rice balls on the cabinet, and smiled.

Wang Ziyu wiped his face for a moment, then stared at Jing Guang expressionlessly.

childish!

He and Jing Guang live in a double room, and there will be plenty of opportunities to punish him soon!

Wang Ziyu hung the towel on the hook, turned off the light, and then the light in the living room went out as soon as he came out of the bathroom.

Wang Ziyu "..."

Wang Ziyu turned around silently, preparing to go back and turn on the light in the bathroom.

Then Wang Ziyu heard a faint sound of walking.

Right rear! ! !

Wang Ziyu jumped to the left!

But there seemed to be nothing. Wang Ziyu closed his eyes and listened carefully to his surroundings.

Wang Ziyu has not yet adapted to the suddenly dark environment. His eyes cannot see anything now. He is thinking about the floor plan of the living room before turning off the lights, and then suddenly remembers that there is a cabinet in front of me in the direction I jumped over. It is impossible. Someone!

Can only appear from behind or from the left and right sides!

At the same time, a sound of wind moved towards Wang Ziyu from the left!

Wang Ziyu ducked and moved to the right while kicking a slipper over.

Snapped! Pa…pa…

Kicked you! ! !

Wang Ziyu felt a little proud. Today he came here to express his resentment. It would be best if he had a good fight!

Wang Ziyu stepped lightly, moved to the right, secretly opened his eyes, and suddenly realized something was wrong.

He could see somewhat clearly now, but he wasn't there! !

The whole body remains highly alert, adrenaline begins to rise, and one pays careful attention to the surroundings.

Then a small black shadow hit Wang Ziyu at an extremely fast speed!

The speed is too fast and the body cannot avoid it!

But that's just an arm!

Wang Ziyu's eyes narrowed,

good chance! ! !

He raised his hand, tilted his head, and while grabbing the opponent's wrist, he used force under his feet and jumped up!

In mid-air, Wang Ziyu grabbed the opponent's wrist, turned around in the air, and kicked the person's head fiercely with his right foot!

Before the kick could hit the head, he kicked hard on the opponent's small arm that was blocking it!

Wang Ziyu had long known that he would be blocked, so he hooked his right ankle downwards on the blocking arm, released his hands at the same time, leaned back, and kicked his chin fiercely with his left leg!

Zhu Fu Jingguang stepped back and avoided Wang Ziyu's left kick!

Wang Ziyu felt it with his right foot when the opponent made a move, and he wanted to avoid it!

At the same time, Wang Ziyu let go of Jingguang's arm with his right foot, lifted it up, and leaned back with the power of his left foot.

Putting both hands on the ground, bending the arms, pressing both feet on the ground at the same time, he did a backflip and stepped on the wall behind him!

He jumped suddenly and stepped hard on the arms folded in front of his chest with his right foot!

Wang Ziyu raised his left foot upward, preparing to hook his neck.

Then Jing Guang thrust his arms upwards, stepped forward and downwards at the same time, gently hugged Wang Ziyu's calves, stood up suddenly, and threw them back with all his strength.

This trick works well!

Wang Ziyu's eyes shone slightly.

Wang Ziyu's left foot lost its support point, and he could only move forward. Using the impact force he brought, he threw himself over with only a small amount of force!

As Wang Ziyu moved forward, he stepped on Jing Guang's shoulder with his left foot and turned his body from forward to leaning back.

He stepped on the floor with a half backflip, and jumped back slightly twice to remove the excess impact.

Stand up, put on a standard offensive image and talk to the opponent

"You're practicing well, Jingguang."

Jing Guang walked to the bathroom, turned on the light and asked.

"Want to fight outside?"

Wang Ziyu went to the shoe rack, turned on the light, started putting on shoes, and said.

"Okay."

After Jingguang went to the bathroom, he walked to the bedside with a trace of invisible resentment, and said while adjusting the quilt.

"No, you should go to sleep."

Wang Ziyu "..."

? ? ? ?

Wang Ziyu paused and turned around, "Are you kidding me?"

I've put on my damn shoes, grabbed my keys and am ready to go out!

Then Wang Ziyu took off his shoes and lay on the bed. Then he became more and more angry as he thought about it, but it happened that he fell asleep first!

I rely on!

Why did you fall asleep first?

I only squinted for twenty minutes!

Can't sleep...

I can't go out either. There are all couples outside now.

It's all dog food, and his mentality is about to explode.

Wang Ziyu sat up from the tatami. He may have understood Jing Guang's feelings. He went to the toilet and washed his face, then put the quilt on the sofa in the living room. He took out the computer, pen and paper from the suitcase and started to design. picture.

Turn resentment into motivation and overcome the next difficulty.

infrared sight

First of all, the previous generation successfully developed a photocathode with extremely high sensitivity.

The sensitivity can be improved by an order of magnitude compared to the external photocathode, which can greatly improve the photoelectric gain of the night vision device.

Another breakthrough is fiber optic panels. It is a thin plate array composed of a large number of optical fibers, each fiber conducts one pixel to reduce light scattering.

The conduction effect is good. Because the ends of the fibers can be arranged into a curved surface, aberrations are naturally avoided and the imaging quality can be greatly improved.

The size of the night vision device is greatly reduced, the quality is reduced by half, the price is reduced by half, but the sensitivity is greatly improved.

However, technology is still catching up...

Wang Ziyu closed his eyes, rubbed his temples and sighed. The development of this kind of weapon is still too fast. It is difficult for one person to surpass a group of people.

Copy the previous generation technology, write a detailed explanation, and download it.

While waiting, Wang Ziyu sent an email to his first contact person.

[For special bounty tasks, please contact your superior. ]

[OK]

The liaison officer on the other side was a little shocked. According to the informant's information, Ran was in Japan now. Could it be related to research again?

Could Ran be an organization? The liaison officer complained for a moment, then reported it to his superiors.

Although the liaison officer sometimes complains that he is a technician who is not doing his job properly, he still respects Ran very much.

Bi Jing is a strong man.

Then his superior comes, and the liaison officer goes out first. Major matters will be kept confidential by subordinates to prevent information leakage.

Wang Ziyu did some operations, and the two of them encrypted the information respectively. After confirming that there would be no problem in the duel, Wang Ziyu sent the information.

Scope, infrared scope, night vision device.

There is another material

Gallium arsenide, black gray solid, melting point 1238c. It is below 600c, can exist stably in the air, and is not corroded by non-oxidizing acids.

It is a semi-insulating high-resistance material used to make integrated circuit substrates and some detectors.

Semiconductor devices made of gallium arsenide have the advantages of good high-frequency, high-temperature and low-temperature performance, low noise, and strong radiation resistance.

Transistors made of gallium arsenide have small amplification and poor thermal conductivity, making them unsuitable for high-power devices.

Although gallium arsenide has superior properties, because it decomposes at high temperatures, it is technically demanding to produce high-purity single crystal materials with ideal chemical ratios.

resolve resolution:

Figure XIII-20 Gallium arsenide preparation device...

The device for preparing gallium arsenide is as shown in the figure. First, a quartz disk containing pure gallium is put into a transparent quartz ampoule with one end closed, and then pure arsenic is added. Under... conditions, it is vacuum sealed.

To prevent the gallium arsenide and the disk from getting wet, the inside of the disk must be sandblasted about 150 to 300 times.

……

Install the above-mentioned ampoules as shown in Figure ).

加热到610c的砷的蒸气压为101.325kPa，与加热到1250c的镓进行反应，产生砷化镓。经过4～5h后，将安瓿每1h往A炉拉出5～20mm，则从盘的前端逐渐生长出单晶。

Storage method:

Keep the receptacle sealed and stored in a cool, dry place, and ensure there is good ventilation or exhaust in the workspace.

Toxicological data

ecological data

It is extremely harmful to water and harmful to organic matter in water...

No known hazardous reactions. Avoid acids, moisture/humidity.

The man raised his eyebrows when he saw Gallium Arsenide, and after copying it into the special disc, he responded to the news about hair dyeing.

[You even went to school. How many teachers do you need to learn so much? ]

Wang Ziyu looked at the email and replied with a smile.

[There are so many of them, people I know, people I don’t know, people I’ve only met once, I can’t even count them. ]

[Do you work so late every day? Be careful of getting bald at a young age. ]

[It’s also dark in China now, and so are you at this late hour. I’m still young and can’t be bald. ]

[You do such dangerous tasks every day, why don’t you consider coming back and becoming a researcher? ]

[I’ve thought about it, and now I’m also working as a researcher. Well… I basically won’t do anything that’s particularly dangerous. ]

[Come on, that time two years ago...]

The person opposite sighed. It was too dangerous that time. He continued typing.

[Although you survived in the end, what if, if you don't come back alive, it will be a huge loss to everyone. ]

Wang Ziyu looked at the computer quietly.

silence

It was two years ago again...

The light from the computer shone on Wang Ziyu's calm face. It was dark outside and the light inside was a bit dazzling.

Her bangs hung down, blocking her eyes and making her expression unclear.

I silently sent a few emails to the other party, and then closed the computer.

The surroundings were completely plunged into darkness

It took about half an hour for Wang Ziyu to come back from his thoughts, and he still kept staring at the computer.

He sat up from the sofa, put the quilt back on the tatami, put the computer back into the suitcase, and then got into the quilt and lay down.

For some reason, he just couldn't sleep. He felt a little bored and uncomfortable. Opening his eyes and looking at the ceiling above his head, he had been a little emotionally unstable recently. What was the reason...

I frowned and closed my eyes. I have something to do tomorrow, so I have to sleep.

But his sleep was particularly unstable. About half an hour later, Wang Ziyu got up with his hair disheveled, took out his phone and looked at

3:40

Wang Ziyu "..."

It's almost the next morning.

He sighed and walked to the living room, took out the sleeping pill and broke it into half, then drank it with water.

Back in bed, this time he was completely asleep, but his eyebrows were still slightly wrinkled.

He fell into a nightmare...
