(Thanks to "Mo Ran Shi Ye" for the reward. It's a little late tonight today, I'm sorry.)

If Ding Bao is not wrong, the so-called "ice and fire alliance" in the last article of "The Eight Chapters of Hong Gong's Dream" is actually the legendary "Ice Mirror to Make Fire".

And this ice mirror made by "cutting ice to make the circle" is a convex lens.

After reading this section, Ding Baorui pondered for a while and said in a hurry: "I can try it, but I don't guarantee it will work."

Kong Lianyi's eyes lit up, and almost jumped up, and she cried out in a childish voice: "Brother, can this ice really make a fire?! This is too, too incredible!"

"I said it was just a try. But since the first seven chapters of this book have been tried out, it shows that although Mengyan is a waste, it is not a fool. Why not have more confidence in this last chapter?" Ding Bao said with a smile.

Kong Lianyi was a little disappointed when he heard Ding Bao's explanation. However, thinking of the big brother's unpredictable behavior, he couldn't help but suspect that he was modest, so he regained his spirit and said with a smile: "Big brother, even if he wants to try it, he can leave anything to his younger sister..."

"No need, this may not be possible in just three or five days. If you need anything, I will call your brother to do it."

One sentence made Kong Lianshun tremble all over, his black face turned red, and he almost bowed his head and called for a command to lead the army.

After that, I looked at my sister Kong Lianshun with her eyes, looking unconcealed. I saw it, letting you behave like a ghost, and I drink my brother's foot wash water. You recommend yourself and you can't get it. Brother, I sat firmly on Diaoyutai without saying a word, but I took the initiative and was directly selected by Brother Ning as my arm helper!

"Then the little sister is responsible for helping brothers deliver breakfast every day!" Kong Lianyi seemed to be unaware of it, raised her apple's face and said happily.

After Ding Bao nodded, she looked back at Kong Lianshun with a smile, her eyes narrowed like a little fox who was about to steal food.

Breakfast?!

Still daily?!

Kong Lianshun's face suddenly changed, and his previous color disappeared instantly. He immediately looked at his nose and nose, and his face was solemn, but his heart was bitter, thinking about how to find an excuse to find a sister to relieve it, otherwise it would be dead...

The three of them chatted for a few moments. Before returning, Kong Lianyi couldn't help but be curious and raised her head and asked, "Big Brother, are you sure?"

"It's hard to say. If you want to succeed, you only know the truth, not enough methods, and you still have to have craftsmanship, weather, and a little luck. There are too many unpredictable factors, and I can't predict it now." Ding Bao pondered carefully and answered very cautiously.

Kong Lianyi didn't say anything this time, nodded obediently, turned around and left.

Ding Bao was so cautious about this matter, not because he pretended to be modest or intentionally hid it, but because he really had no confidence.

The saying "ice mirrors make fire" has been around since ancient times, and the principle is very simple. Cut the ice mirror into a flat circle, and the two sides are bulged into a spherical surface. Then, facing the strong sunlight, the convex lens focuses on the principle of heat generation, ignite dry firewood and make it fire.

Similar principles, there is also a magnifying glass I played with when I was a child.

But many things are easy to know but difficult to do. Ice cubes are different from glass products after all. First, it will slowly melt under the strong sunlight. Secondly, it is difficult to ensure that the ice surface is absolutely smooth. Moreover, the bubbles in the natural ice are difficult to eliminate, and they cannot guarantee absolute crystal clearness. They will cause various refractive scattering when the sunlight passes through, and cannot completely gather heat...

Anyway, there is a fact that, as a child who grew up in the north, Ding Bao had to go to Heli Lake to fish for ice every winter since elementary school, but he never succeeded. Until he was in his sophomore year, he read relevant records that Zheng Fuguang of the Qing Dynasty used a concave tin pot, filled it with hot water, and placed it on ice cubes to rotate it, and obtained a well-shaped ice convex lens, which was used to focus on the sun to burn the coal.

Inspired by this, he experimented countless times before finally succeeding. And that time it was a non-natural ice frozen in the refrigerator with a porcelain bowl, but now, the refrigerator that ghost came from?!

"Brother Ning, I'm ready. Let's start quickly! What to do first?!"

Kong Lianshun rolled up his sleeves, raised his chest and abdomen, and was ready to rub his hands. Due to his emotional excitement, a layer of oil even appeared on his dark face.

"Lunch break."

“…”

In my memory, Confucius has not had such urgency and excitement for a long time.

After Kong Lianyi brought back Ding Bao's reply that day, "Let's try it, but I'm not sure", she actually no longer had any hope in her heart.

Because of this matter, she tried it bit by bit for nearly ten years, and almost tried all kinds of methods, but not only did she get nothing, but she couldn't even see any signs of getting closer to success.

This extremely rare helplessness and depression became an indelible obstacle and nightmare in her heart that pursues ultimate perfection in everything.

The reason why she asked Ding Bao to entrust this matter to ask for Ding Bao on that day was not only an impulse caused by emotions, but the most important thing was that she hoped that this magical Young Master Ning had heard and witnessed it, or had made similar attempts personally. She would not ask for it, but could not succeed, even if she could provide some new ideas.

But from the feedback, Ding Bao didn't seem to have tried in depth, so he felt very regretful and disappointed.

Unexpectedly, less than two days later, the road suddenly changed, and the willows and flowers were bright. I actually sent a message over there, and made an appointment to walk to the singing pavilion west of the city to show the wonder of the "Ice and Fire Alliance".

So she didn't know how she spent this day, but she felt that every minute was so difficult. For the first time in her life, she truly understood the profound meaning of the word "living a day is like a year"...

I didn't sleep much all night, and early the next morning, I was still energetic. I washed and dressed up in a serious manner, and then called Kong Lianyi to prepare the carriage. Kong Lianyi was yawning and complained hard. It was too early, so I dragged her to eat breakfast, and then beat her. The first time I beat her, and the little girl screamed...

As they counted, the two of them took a bus and rushed to the green singing pavilion before noon.

Kong Ci and Kong Lianyi travel together, without giving instructions, someone cleared the venue in advance. Therefore, in the past, in front of the singting pavilion, which was sent to the farewell, there was only an ordinary red-painted carriage parked.

"Big brother and the others have arrived." Kong Lianyi cheered and jumped off the carriage first.

Before Kong Ci got up, he only lifted the curtain of the car, and slightly lifted the veil in front of the hat, revealing a pair of bright gauze that was as bright as the Mid-Autumn Festival full moon and the white skin as white as snow. On it, there were some weird and shiny clouds of roses.

Two shallow and curved eyebrows are indifferent and alien, but extremely elegant, but they are pure white.

"Huh, why are you the only one, big brother?"

"Brother Ning has taken one step ahead. Today's experiments are all displayed by me, my brother, I'm sorry."

"Bah, nonsense! Big brother hasn't said goodbye to me yet!" Kong Lianyi said angrily with her hips, rushed into the carriage with a fierce momentum, searched for a while, and when she got off, her mouth sagged, and it seemed that she was about to cry.

Kong Lianshun knew that he was entangled with her and stopped talking nonsense. He moved the freezer out of the car and opened it. A cold air came to his face. The bottom floor and the four walls were filled with freezers made of ice, and there were three large, bright ice mirrors in the middle of the freezer.

In fact, this time, Ding Bao has made a big deal to avoid being favored in order to have come and go.

First of all, prepare the materials. In order to ensure that they are crystal clear and not bubble-like, he decided not to use natural ice and make ice by himself.

First boil water in a small wok, boil it and then cool it down. After exhausting the bubbles thoroughly, bury it in the depths of the ice cellar. After freezing it into ice cubes, choose the one with crystal clearness and transparency, and use a knife to carve a thick ice convex lens, that is, it is thick in the middle and thin at the edges.

Then, rely on the temperature of your own hands to melt the two sides of the ice lens to make it more delicate and smooth, ensuring that the edges are thin, and the curves of both sides must be smooth to form a perfect ice lens, just like a real glass lens.

Even if you are so careful and meticulous, the success rate is still extremely low, and the firewood only smokes once.

Although he almost scared Kong Lianshun this time, Ding Bao was very dissatisfied and tried it many times. Only then did he find that with the same fineness, the bigger the lens, the better, so that it can gather more sunlight, so that it can gather enough heat to ignite the firewood before melting.

At this time, the three ice mirrors in the freezer were the three that Ding Bao thought were the most complete and the most exquisite and perfect.

Kong Lianshun has been inseparable from Ding Bao for three days, so he naturally knew that the importance and rareness of these three ice mirrors were equivalent to having three chances to complete. Therefore, although Kong Lianyi around him was no longer noisy and his attraction was all over here, and he was extremely quiet and virtuous, he was still a little nervous.

Taking a deep breath, I put the dry firewood chip pile, took out one of the large ice mirrors, adjusted the angle, moved it over the small firewood pile in front of the sun, silently recited the method of Ding Baojiao in my mind, found the highlights, and then placed the highlights in the dark part of the firewood pile.

There was no waste of a hard-earned ice mirror that could be called a work of art. Before the first ice mirror melted and deformed, the pile of firewood began to smoke, and then slowly started to burn Mars... and then under the careful care of Kong Lianshun, it turned into a large and small bonfire.

The Ice and Fire Alliance succeeded like this! And in such a direct, sharp and indisputable way!

Stepping in front of the singing pavilion, I suddenly fell into a strange silence. For a moment, even the sound of the wind seemed to disappear...

In the small forest half a mile away from the singting pavilion, two riders stood together. It was Ding Bao and the strange old wind. Seeing the smoke coming out of the distance, Ding Bao relaxed his expression and said with a smile: "Kid Kong Lianshun finally got used to it. Let's set off too."

"Since you are worried, why not take action yourself?" Lao Feng rolled his eyes and muttered.

"Some people should try not to meet each other, but some things must be done. I chatted with Kong Lianshun yesterday and realized how great the face it is to borrow this "Yansheng Cao Garden" for two months. If this little girl's family's little dream is not done, she will have no face to live there..."

As he was speaking, a woman's graceful singing suddenly sounded over there. Every word was ancient, and her meaning was unclear, unlike the graceful and lingering of an ordinary woman, and even more like a golden sword and an iron horse, a sturdy meteor, with a heroic and singular feeling that reached the heart.

Ding Bao was stunned: "Has she found me?"

"Wrong. No one in the world knows that the beloved daughter of Confucius is always surrounded by two masters who are among the top 100 lucky masters. Whoever has the malicious will die. They will naturally find you."

Ding Bao felt a little nervous. After closing his eyes and listening to the song for a while, he suddenly laughed loudly, turned over and got off the horse, slapped the horse's butt, and let it go back to the mountain, "Old Feng, let the horse go, how about the two of us? I count to three, let's go together."

"Okay." Lao Feng was overjoyed and followed suit, dismounted and released the horse.

"three."
