With the return of Yan Yun and others one after another, all kinds of materials were delivered one by one, bamboo strips, thin silk, lamp oil, cotton, paste, ...... Sun Yu only took a few dozen minutes to tie up a small hole lantern only one meter high, about the size of a drum washing machine in later generations, this size of the small hole lamp is definitely not high, Sun Yu just made the first test of it.

Because he had never made a Kong Ming lantern before, in order to prevent a mistake, he made a small one first.

A small hanging basket was made under the large Kong Ming lantern of the television, and a thin shell was placed in it, and some lamp oil was filled in the shell, and a ball of cotton was soaked in the lamp oil to be used as a medium for combustion.

Huang Yueying squatted beside her and watched quietly, staring at Sun Yu's movements with a pair of eyes, when she saw the gear set and Sun Yu's wooden ox and flowing horse, she had already thought that this man was a very powerful craftsman, and later heard Zhuge Liang talk about Sun Yu's wheels, and her heart was even more upbeat of Sun Yu, at this time she saw Sun Yu making "toys" with her own eyes, for fear that she would miss every place.

However, seeing Sun Yu adding lamp oil or something under Kong Ming's lamp, she really couldn't understand it, and couldn't help asking: "Mr. Xunzhen, are you going to use the fire to roast your 'bamboo dragonfly' and fly upward?" It's a dead thing, and it won't move even if it's roasted over fire. ”

Sun Yu smiled: "This is a kind of power, the heated air will expand, lighter than ordinary air, so it will float upward, driving me to make this thing and fly into the sky......"

"And that kind of motivation?" Huang Yueying blinked her big eyes, a little disbelieving.

"Well, just watch quietly, and you'll know in a while." Sun Yu grinned.

Sun Yu asked the soldiers to lift the Kong Ming lantern up, hang it in the air, and then ignite the cotton in the hanging blue below, and the flames swooped up, this time it was so big that it almost burned the main body of the Kong Ming lantern.

Sun Yu hurriedly extinguished the fire.

Huang Yueying covered her mouth and smiled!

Sun Yu's old face was slightly red and said: "Don't laugh, it's just the first time I've done this myself, I haven't done it well, I'll let you see how good I am right away." ”

He kneaded the cotton into strips to make sure it didn't burn too quickly, and then put it back into the oil.

This time, the cotton was lit again, and the flame burned peacefully.

Sun Yu was overjoyed and said: "Hehe, it's done!" ”

"It's finished?" Huang Yueying pointed at Kong Minglan curiously and said, "Obviously I haven't moved at all!" ”

"What's the hurry, it takes a certain amount of time for air to be heated, how can it be so fast?" Sun Yu smiled confidently.

After a while, the air in the Kong Ming lantern was slowly heated, and the entire Kong Ming lantern began to expand, and the main part, which was originally a little deflated, was now bulging like a ball.

"Does the air really expand?" Huang Yueying was taken aback, but what surprised her was still to come, only to see Kong Minglan slowly leave the hands of the soldiers holding it and hang in the air.

As the flames continued to blow hot air, the Kong Ming lantern finally fluttered upwards slowly...... Inch by inch, foot by foot, taller than a man's head, taller than the waist of a small tree, and taller than the treetops of a big tree...... Finally, it's time to fly!

Sun Yu wiped a handful of sweat on his forehead, thinking: His sister's test was finally successful, fortunately, it was successful once, if it didn't succeed, it would be embarrassing, and she would be laughed at by this black girl to death.

At this time, Huang Yueying still had the heart to laugh at him, she stared at a pair of big eyes, and watched curiously as Kong Ming's lantern floated higher and higher in the sky, higher and higher...... Heating air as power? This is also amazing, the gear set last time has opened her eyes, and this time Kong Ming Lantern simply subverted her common sense.

Huang Meizi bit her lower lip, in the field of craftsman manufacturing, she is very strong and can't tolerate losing to others. The last time Sun Yu defeated her wooden cow flowing horse with a wooden cow flowing horse, she quickly used the "Gongshen" and used her unscientific power system to save a little face.

This time Sun Yu made another new move, Huang Yueying was willing to admit defeat, she waved her hand, and the bamboo dragonfly immediately flew up, chasing Sun Minglan and flying into the air. The Kong Ming lantern flew very slowly, but the bamboo dragonfly flew very fast, and soon the bamboo dragonfly exceeded the height of the Kong Ming lantern, pressing the Kong Ming lantern on one end, as if showing off its might.

I saw that the bamboo dragonfly and the Kong Ming lantern flew higher and higher, and when it flew to an altitude of about 100 meters, the Kong Ming lantern finally couldn't fly, because this volume of the Kong Ming lantern could only reach this height, and the weight of bamboo strips, lamp oil, thin silk and other things limited the buoyancy of the Kong Ming lantern, and it was impossible to achieve better results.

Huang Yueying saw that Sun Yu's Kong Ming lantern couldn't fly, so she immediately breathed a sigh of relief and said proudly: "Mr. Xunzhen, it seems that this thing of yours can't compare to my bamboo dragonfly." You've lost! ”

Sun Yu laughed and said, "Who said I lost?" The one just now was just for experiments.,I haven't started to officially compare with you.,Next, let you look handsome.。 ”

Sun Yu hurriedly buried his head in hard work, and this time he went out, and with the help of the soldiers, he actually made a huge Kong Ming lantern the size of a house. With the technical reference provided by the test surname Kong Ming lantern just now, the production of this large Kong Ming lantern in this house was very smooth, and it only took one hour to announce the completion.

This huge Kong Ming lantern startled Huang Yueying, and she began to feel a little uncomfortable in her heart.

Sun Yu shouted: "Ready to fly!" ”

Several soldiers climbed the big tree next to them and lifted the big belly of Kong Ming Lantern from the treetops. Sun Yu walked under the lamp and laughed loudly: "Miss Huang, I will officially compare with you now...... Look at this ...... of mine Well...... Is the truth lamp better than your bamboo dragonfly? ”

The "boom" cotton ball was ignited by Sun Yu, and the scorching air rushed up, and the hot air poured frantically into the belly of the giant Kong Ming lantern.

Everyone watched with wide eyes as the deflated Kong Ming Lantern's belly grew bigger and bigger, bigger and bigger, and more and more inflated, and finally, the belly of the entire Kong Ming Lantern bulged like a huge leather ball.

As soon as the soldiers' hands were released, the huge Kong Ming lantern slowly floated upwards and left the ground.

"Wow, it's flying!" The little Lolitas applauded happily, such a huge toy had never been seen before for them.

A drop of cold sweat flowed down Huang Yueying's cheeks, and she watched this huge ball rise into the air, not knowing why she already felt like she was going to lose. No, you can't be timid.

With a wave of Huang Yueying's small hand, the bamboo dragonfly immediately flew up lightly and skillfully, chasing Kong Ming Lantern and climbing into the air.

The bamboo dragonfly is only a few centimeters long, and it looks too small next to the huge Kong Ming lantern. The two chased each other, climbing towards the sky.

100 meters, 200 meters...... After a short while, both of them flew into the distant air, and by this time the bamboo dragonfly had turned into a small black dot, which could hardly be seen clearly, and no one could see it if it were not for a layer of golden light wrapped in it. But the huge Hung Ming lantern is still clearly visible.

The little Lori's eyes unconsciously left the bamboo dragonfly, and they all stared at the Kong Ming lantern.

300 meters, 400 meters...... Huang Yueying began to feel that her golden light was a little out of control...... The flying of the bamboo dragonfly began to struggle.

She gritted her teeth, her body shook, and more powerful golden light shot out from her, reflecting everything around her, and the bamboo dragonfly seemed to have eaten enough, and it had a new momentum, and continued to chase the Kong Ming lantern to climb up.

500 meters, 600 meters...... The bamboo dragonflies have begun to wobble and are overwhelmed.

Sun Yu knew that the golden light emitted by Huang Yueying's "Gongshen" was almost at the limit of its range because of the diffusion of light particles.

However, the limit of Kong Ming lanterns is still very early!

Sun Yu couldn't help but smile and said to Huang Yueying: "Miss Huang, the bamboo dragonflies can't see clearly, you better give up." ”

"No, I'm going to compete with you to the end." Huang Yueying tried her best to release the golden light, poor Huang Yueying, in order to drive a small bamboo dragonfly, actually did not hesitate to spend a lot of energy and released the golden light crazy.

700 meters, 800 meters...... At this time, even the huge Kong Ming lantern began to turn into a small ball. As for the bamboo dragonfly, ordinary people have long been unable to see clearly. Sun Yu needs the help of nm01 to see, and as for Huang Yueying, she can't see it at all, so she can only rely on her own golden light to maintain the induction between the bamboo dragonfly and her.

Hate, what's going on with this weird thing called "Truth Finder Lamp"? It's already flying so high, it can still fly upwards without stopping...... My bamboo dragonflies are getting out of control, how did he do it? Huang Yueying thought a little depressed in her heart: I lost the last time I lost the wooden cow and the horse, and I saved a little face by relying on my martial arts skills, this time I ...... Is it any wonder that I can't save it with my martial arts skills?

This man ...... How could he possibly create something more powerful than martial arts? I don't believe it! I don't believe it!

Huang Yueying gritted her teeth, a touch of weakness flashed in her eyes, and she also bet her last energy on the bamboo dragonfly, and in the golden light, the black skin of her whole body turned golden.

Sun Yu glanced at her curiously, and found that Huang Yueying, who had turned golden skin, was very beautiful, tens of thousands of times more beautiful than the appearance of yellow hair and black skin, wow, if this guy wiped it with those whitening things in later generations, he might be a big beauty!

At this time, Kong Ming lanterns and bamboo dragonflies had already flown to an altitude of 900 meters!

Huang Yueying suddenly put away the golden light, her body was weak, and she fell backwards, it turned out that her energy was finally exhausted, poor "Gongshen", if the distance was close to her light projection effective range, she could command hundreds of trebuchets at the same time, but in order to command a bamboo dragonfly that was too far away from the spread of light particles, it was too tragic to exhaust her energy.

The bamboo dragonfly in the sky lost her command and immediately fell softly, Huang Yueying reluctantly watched as Kong Ming's lantern flew higher and higher, breaking through a thousand meters in the air, and still climbing upward...... Huang Yueying's fallen body was quickly grabbed by Sun Yu's eyes, and she didn't fall to the hard ground.

"I lost!" She lay softly in Sun Yu's arms, and sighed: "Mr. Xunzhen, you actually defeated my 'Gongshen' with your craftsman skills, you are the real craftsman, Yueying is convinced." ”
