God of danger

The two went to Brother Ming's office first, Lu Rongxing was outside, watching Guan Jie making a report inside through the door opening.

"Coach," Guan Jie smiled flatteringly, "I want to use the key to the laboratory."

Brother Ming was facing the door and was reading technical documents behind the big-ass computer. Hearing this, he raised his eyes and glanced at him: "What is it for?"

Guan Jie had an obedient look on his face: "I want to do the lead iodide experiment, and I promise not to touch other things."

He is an honest guy, let me take metal sodium the size of a mung bean, but definitely not the size of a soybean. Brother Ming is actually quite at ease with him, but he doesn't dare to let him mess around, just in case something goes wrong, everyone Can't afford it.

But it’s a good thing that students have a desire to explore, and he and Yuan Jin are frequent visitors to the laboratory. Brother Ming let go of the mouse and stood up: “I can’t give you the key, right? Potassium iodide and lead nitrate, how much do you want?”

Guan Jie stretched out his index finger: "Just 1g each."

Old Ming brother tilted his upper body to look for the keys in the drawer, and saw Lu Rongxing outside.

He also knew this student. On Saturdays, he always came to the classroom to find Guan Jie to go home with him. He was a well-bred boy. Before, he had pasted a printout of "outsiders do not enter" at the door of the laboratory, and this child had never entered.

Until one time when the northwest wind was blowing too hard, Guan Jie was showing him the cooling device again, so he couldn't leave immediately. Brother Ming was afraid that he would catch a cold, so he went out and called someone in.

Guan Jie spared his rare free time to be cool, and suddenly ran back to do experiments. Brother Ming shook his head secretly and smiled, thinking that he was still a snotty child after all, and he had to show off in front of his buddies, but he would probably pretend even more when he was in front of girls .

But this is also the advantage of being young, with a strong personality, and will do a lot of things that are useless to the elders, but I find it interesting and fun.

At this moment, Brother Ming suddenly remembered that when he was young, he also stole things from the laboratory to do thermite reaction. The sparks in that night were so dazzling that he seduced his three souls and left his seven souls. After that, he walked on the road of chemistry For more than 20 years, he remembered many things in the laboratory, but the classmates and friends who were messing around with him disappeared, and everyone basically changed careers.

Many people are clamoring to do it and cherish it, and in the end, most of them are scattered in the end, but the time we spend together is not regrettable. Those laughter and noises will never be there again in the future life.

So as long as it's not out of line, if they want to play, let them play.

Old Ming hooked his finger on the key ring and walked out of the office to the laboratory, followed by two big tails.

There was a faint smell of medicine all the year round in the laboratory, as soon as the three of them entered, Brother Ming asked Guan Jie to open the window.

Guan Jie pushed Lu Rongxing down, pointed to the right, and went to the left by himself. The two opened the two windows in a swish, then merged from the left and right, and gathered next to the gloved coach in front of the medicine cabinet.

Old Ming had been soaking in the laboratory for many years. He basically didn't need to use a scale to weigh the reagents in grams. He put on a gloved medicine spoon and scooped up a little crystal each, and poured them into the two Erlenmeyer flasks held by Guan Jie.

1g may not be absolutely accurate, but it should be close.

"The water you add for the first time should be hot enough," he said as he handed the medicine spoon to Lu Rongxing, and he went to lock the door of the cabinet where the reagents were stored, "The time for heating and dissolving should not be too long, there is a seven or eight Ten degrees is enough, otherwise the effect will not come out.”

Guan Jie read the scriptures seriously: "Understood, thank you coach."

Brother Ming took off his gloves, went to get the utensil keys on the key chain, and told him to wear gloves, pay attention to evaporation, pay for damages, wash them after use, etc. After talking, he took the rest of the keys and went out.

Guan Jie responded with a lot of voices, and while watching him go out, he put the flask on the experimental bench, and then went to get things, gloves, alcohol lamp, iron stand, asbestos net and beaker.

Lu Rongxing was not idle either, he stuffed a beaker and ordered: "Go to the coach's office and get a cup of hot water."

Then when he came back after receiving the water, he saw Guan Jie was adjusting the height of the iron ring, with his upper body bowed and his head lowered, his bangs hanging naturally covered his eyebrows and eyes, his side profile was soft, and his movements of turning the handle were steady and slow. There is a sense of stability and reliability.

Steady and Guan Jie, in Lu Rongxing's nascent consciousness, should be a pair of contradictions, but the years have moistened things silently, and rewritten his stereotype bit by bit. Now when he sees such Guan Jie, he just feels that there is something wrong in his eyes. Pleasant to the eye and at ease.

Lu Rongxing returned to the operating table with hot water, sat on the chair next to him, and looked at the two handfuls of pitifully small white particles. Due to the distance between them, he couldn't imagine the relationship between them and money. .

But he didn't ask anything, just sat quietly and watched Guan Jie busy.

Standing in front of the stage, Guan Jie first touched the boiled water that Lu Rongxing received through his gloves. He felt that the edge of the wall was very hot, and the temperature should be enough. Then he picked it up and poured it into one of the flasks. Shaking gently in mid-air.

Brother Ming had very high requirements on their operations, and those who didn't obey orders would be swept out of the house. Guan Jie liked to do experiments and didn't dare to act rashly.

The liquid undulates around the wall of the cup, and the drop caused by the rise is not large, which shows that the force of the shock is even, and the particles are quickly dissolved, leaving only a small half of the bottle of water-like liquid.

There was some condensed water hanging on the edge of the wall, Guan Jie didn't care about it, just picked up another flask, and made a gesture of preparing to pour liquid into it.

If he is a qualified performer, he should say that the time to witness the miracle is coming soon.

But Guan Jie didn't fix these mysteries, he just looked at Lu Rongxing, smiled and reminded: "Look at the cup on my right hand."

Lu Rongxing nodded and stared at the cup.

Guan Jie slowly turned his wrist, and the moment the sound of falling into the water appeared, Lu Rongxing saw the transparent solution smash into the empty glass bottle filled with white salt grains, and a bright yellow suspension was instantly produced.

Its color looks like multi-concentrated non-residue orange juice, and the state of spreading in the continuously injected transparent liquid is like egg white or milk. The color is bright and full, and the state of spreading is like a majestic sea of ​​clouds.

This bright yellow sometimes fades, and as Guan Jie is poured, the yellow in the bottle becomes brighter and brighter, and countless tiny golden fragments float and sink in the water. To use an accurate word to describe it, it is radiance.

It's not that Lu Rongxing has never seen a chemical experiment. He has seen the scene of sudden color change several times, but the visual impact is not as strong, because it is reflecting light and has a rich and fluid state.

The temperature difference makes condensed water quietly hang on the wall, which somewhat blocks the line of sight.

Lu Rongxing unconsciously moved a little closer, wanting to see the process of "growth" of the gold piece more clearly.

At this time, Guan Jie just emptied the flask in his left hand, and while putting it down, he saw Lu Rongxing approaching a little bit, and quickly raised his eyes to look at him: "Don't get so close, this is a bit irritating, and it won't hurt to splash it on your body." Great."

Watching a movie is good, but safety is more important. Lu Rongxing listened to Teacher Guan, sat back honestly, and said curiously: "No wonder you say that you feel rich when you look at it. What is this thing that looks like gold powder? "

Guan Jie picked up a glass rod, stirred it in the bottle with a small jingle in his hand, and said, "It's the crystal of lead iodide, does it shine?"

"Flash," Lu Rongxing smiled, looked at the unused equipment, and guessed casually, "Then what are you going to do, heat it up?"

"Yes, heat it up to make it more shiny," Guan Jie said, putting the stirred golden solution on the asbestos net, then lit the alcohol lamp, and moved it directly under the beaker.

Lu Rongxing didn't know what the effect was more shining than the gold powder. He stared at the boiling flask inquiringly, and then saw the golden color disappear little by little, the solution continued to clarify, and turned back to colorless.

He glanced at Guan Jie in surprise, his face seemed to be written peacefully, the promise was even more flashy.

This is what Guan Jie wanted, without saying a word, he tilted his head at him like a joke, and then lowered his head to take care of the movements of his hands.

Lu Rongxing saw that he first took the thermometer and measured it in the solution, then looked at the thermometer against the light, then took the alcohol lamp and capped it, grabbed a rag and moved the flask down.

The essence of this experiment is that the light should be good and the glass bottle should be clean. After Guan Jie put the flask on the table, he wiped the outer edge with a rag before putting it in front of Lu Rongxing.

There was still half a jar of water in the bottle, and there was nothing else. Lu Rongxing missed the shiny golden feeling a little bit, and asked him, "Is it finished?"

Guan Jie let out a "hmm", took off the rubber gloves, twisted the cuffs and put it on the side of the instrument, left the operating table, went to the back of the classroom, squeezed some hand sanitizer, washed his hands under the nearest faucet, and then came back Hooking the bench with his feet, he sat across from Lu Rongxing.

Lu Rongxing was looking at a water bottle, but he didn't see any flowers, so he had to look at him.

On the way back, water had already been rubbed on Guan Jie's pants. After sitting down, he lay down on the stage, propped his chin with his left hand and said, "Wait a while, when the water is a little colder, the stuff will come out."

Lu Rongxing sat upright, and the two of them were separated by a table, their eyes focused on the glass bottle that was closer to Lu Rongxing.

Guan Jie knew what he was waiting for, he was just a little worried that the effect would not be satisfactory, but Lu Rongxing was inexplicable, but this feeling of waiting for the unknown is also quite good, suitable for him who is a little impetuous today.

Occasionally they would meet eyes and smile at each other for no reason.

The winter weather did not keep them waiting, and after seven or eight minutes, a silent change quietly appeared in the flask.

The two raised their eyes at the same time, ready to remind each other, their eyes met again in an instant, and they lowered their eyes at the same time knowingly, to look at the bottle.

In that section of transparent water, granules or flakes of crystals began to appear. They flashed out of thin air, and then fell slowly. The size was bigger than before disappearing, and the solution did not turn yellow as a whole. Lu Rongxing could see every piece The location where crystals suddenly precipitate.

While they piled up to the bottom of the bottle, more and more precipitated from the top. This process gradually changed from slow to fast, and gradually the golden luster covered every corner of the entire bottle, shallow at the top and deep at the bottom. striking.

This scene is almost magical, it looks like something out of nothing, and the picture is also very beautiful, like a golden snow floating in the transparent world in the bottle.

It was the first time Lu Rongxing saw this effect, and he felt astonished in a trance.

He raised his eyes to look at Guan Jie, bumped into Guan Jie who was also looking at him, and the two stared blankly at each other for a moment, one was slightly delighted to see a beautiful thing suddenly, the other was faintly relieved.

Charming grows thinly in the air, but it is not so thick that it makes people feel ambiguous.

Guan Jie was quite satisfied with the effect and Lu Rongxing's reaction. He looked into the other person's eyes frankly, and said softly, "Is it cool?"

"Cool," Lu Rongxing felt that he was cool with half of his face blocked by the flask, and wanted to remember it, so he smiled and said, "What's the name of this experiment?"

In the world of the Internet later, this experiment was dubbed "Golden Rain" by talented netizens, and it was listed as one of the most dazzling chemical experiments along with the most ferocious "Pharaoh's Snake" in the expansion reaction.

But at that time, smartphones were not popular yet, and it was called the dissolution and crystallization of lead iodide. Guan Jie had already mentioned it when he went to discuss reagents, and now he was going to repeat it, but when the words came to his lips, he saw Lu Rongxing looked a little more relieved than before.

The purpose of this experiment was to replace jokes, Guan Jie paused for a moment, always hoping that he would be happier, thought for a while and said, "I told Lu Rongxing to laugh so hard after watching it."

There is no such a nonsensical naming method, and Lu Rongxing's big teeth are still strong, but he laughed out loud, because the name of this experiment sounds very frustrating.

Guan Jie doesn't care whether he is frustrated or elegant, anyway, seeing him smile, he thinks the name is not bad.

Half a minute later, Lu Rongxing finished laughing speechlessly, feeling a lot more relaxed in his heart, and gave a comment with a low laugh: "What a mess."

Guan Jiexin said nonsense, I was kidding you.

At the same time, he still hasn't forgotten the premise in his mind, and he is distractedly pondering the implication of the sentence that he looks alike.

Lu Rongxing did not resemble Uncle Jianxin in any way, and suddenly there was a resemblance, it was Guan Jie, the bloody and arrears head, and he also thought of the possibility that they might not be his own.

Uncle Jianxin devoted his heart and soul to him, and based on Guan Jie's understanding of him, he felt that he would not sneak out of the house just because he had no blood relationship, and there must be something else interfering with him.

Leaving aside the other unknowns, Guan Jie thought to himself, he came to school to look for him, was he in the same mood as when he came to look for him when his grandma passed away?

Of course Lu Rongxing knew it well, but he didn't want to say thank you either. If these things were used between him and Guan Jie, it would be very strange.

The "heavy snow" in the bottle was still rising, but the momentum had diminished a lot. Lu Rongxing looked at it for a long time, watching it gradually clarify and distinguish clearly.

Then his state of mind also seemed to have undergone a precipitation. At this time, his rationality slowly returned, and those words that were difficult to utter under the complicated and difficult thoughts were suddenly not as coy as before.

When the water in the flask was still a little warm, Lu Rongxing broke the silence and said suddenly, "Guan Jie."

"Huh?" Guan Jie responded immediately, and looked up at him at the same time.

There was a touch of concern in his eyes, Lu Rongxing leaned his upper body forward, leaned his chest against the edge of the table, and got closer to him, his heart was slightly sore before he opened his mouth, maybe there was a little grievance mixed in .

"I'm not my father's own. The one who came here today is, but I knew about it a long time ago because I met him in Matsutoyo before. But my father didn't know...I didn't tell him, I Mom probably didn't say anything, but what would he think when he found out?"

Guan Jie raised and lowered his eyebrows when he heard it, he couldn't keep up with his plot.

He thought that Lu Rongxing was sad that he was not his own, but he didn't expect this guy to know that he was still a student, but it turned out that Lu Jianxin was worried about him.

This knot in his heart caused him to feel astonished, as if a stone had been crushed suddenly, a dull pain like lack of oxygen floated up in his heart.

Lu Rongxing is the eldest brother next door, and his parents only follow him. Guan Jie used to envy him very much, but he never imagined that there are so many things behind his being favored.

Guan Jie didn't envy him anymore, he just stood up in the increasingly fidgeting, walked around the side of the table and stood in the row of Lu Rongxing, hugged his shoulder and patted him soothingly, calmly and calmly. Said gently: "Don't think of Uncle Jianxin...too dull, right? He is in business anyway, and he is smart. How could he not know something that you, a student, know?"

"Besides, in this kind of situation, it's not always the child who suffers the most. Are the parents thinking about the child? Are you on the wrong side?"

Lu Rongxing leaned against him, although his last sentence was a bit funny, but after thinking about it, Lu Rongxing felt that it was not unreasonable.

Guan Jie felt the leaning force brought by him, passed his right hand through the front of his neck, formed a ring with the left hand on his shoulder, and swayed around him twice, suddenly remembered that he had been forgotten by him. The purchasing group that can cool the dishes three times.

What made him forget his classmates for a long time?It was Lu Rongxing.

Guan Jie had to pull him to be a strong man, so he continued to shake and said, "I'm going to the supermarket, can I go? Go!"

Lu Rongxing: "..."
