my stealth fighter

Chapter 310 The Ultimate Weapon
The third day happened to be a weekend.

"Come, come, everyone, please come in!"

Qianyang stood on the slope at the entrance of the courtyard and greeted everyone warmly.

Jiang Chanji, Zixuan, Chen Yiyi, Xiaosui, Aurora, Mi Ao and No. 33 got off the bus one after another.

Behind Qianyang is a vast courtyard, different from Mei Yibai's European-style courtyard, this courtyard of Qianyang's family is Chinese-style, with tall courtyard walls and a magnificent gatehouse, both proclaiming the luxury of the owner. The glazed tiles reflect the sunlight, and the copper nails on the gate are slightly dim, full of a sense of age.

"Wow! That's amazing!" Zixuan clicked her tongue.

"It's so-so~no big deal~" Mio said loudly, and was immediately grabbed by the collar by Jiang Chanji.

"Senior Meow, even if it's mediocre, that's not the reason why you want to jump on top of other people's walls!" Jiang Chanji is too familiar with her movements, just as Lu Weijing pointed out, Mio's beast transformation is too successful, Even the brain is partially animalized.

"What... what? I didn't want to jump on the wall! I just thought it would be comfortable to lie on the glazed tiles and bask in the sun..." Mio argued, "Have you ever seen a beautiful woman basking on the beach?"

"Come in, everyone, don't stand and talk outside, you'll get sunburned." Qianyang beckoned everyone to go inside.

Today, Qianyang entertained everyone to play at her own home, and introduced her new friends to her grandpa by the way. Grandpa will be very happy to see that she has made so many friends.

Jiang Chanji was happy to accompany them, because it was expected that there would be a sumptuous meal waiting for them.

A group of people filed into the courtyard through the open gate.

The courtyard is full of emerald green, bamboo shadows whirling, small bridges and flowing water, and winding paths leading to secluded places. The hustle and bustle of the outside world is isolated. Entering the courtyard is like entering another world.

The courtyard is very quiet, the air is fresh and pleasant, with the fragrance of moist soil, a cobblestone path extends from the door to the depths of the courtyard.

Qianyang led everyone along the path. After walking for a while, the bamboo forest parted to the left and right, and a small artificial lake appeared in front of him.

Colorful koi swim in groups in the lake. When they see someone coming, they come out of the water and spit bubbles to beg for food.

Jiang Chanji grabbed Mi Ao by the collar again to prevent her from taking out his fish.

On the shore of the lake is a promenade extending into the center of the lake. An old man in a wheelchair is looking forward to it in the gazebo at the end of the promenade.

"That's my grandpa!" Qianyang pointed in the direction of the old man from a distance, and shouted: "Grandpa! My friends are here!"

Everyone followed Qianyang to the old man. Jiang Chanji felt that the old man's face seemed familiar, but he couldn't remember where he saw it.

On the other hand, Zixuan took a deep breath and whispered, "It's him..."

"Who? Do you know?" Jiang Chanji bent down and asked in a low voice.

"A few decades ago, he should be considered a well-known business star. A few years ago, I occasionally saw him on TV. I didn't expect him to be Qianyang's grandfather, but he is getting old quickly..." Zixuan said in a low voice.

"You know all this? You weren't born decades ago, right?" He wondered.

Zixuan rolled her eyes, "If you take civil and commercial law, the teacher will talk about classic commercial war cases from the past, and he is among them."

"Oh……"

The old man did have a sick face, but his mental state was not bad, as if he was recovering from a serious illness, he happily listened to Qian Yang introducing everyone to him one by one.

When introducing Zixuan, Qianyang specially emphasized that Zixuan is very smart. The old man has always liked smart children. When he asked Zixuan about his problems, he was even more amazed when he learned that Zixuan was actually the best among high school students at such a young age. endlessly.

"By the way, Grandpa, it was sister Zixuan who pointed out that my real ability is not magnetism, but electricity. From now on, don't let me show my abilities to guests. It's a shame!" Qianyang took Grandpa's hand Said coquettishly.

"What's the shame? Whether it's magnetism or electricity, you are grandpa's favorite granddaughter!"

Everyone can see that the relationship between grandparents and grandchildren is really good, and the old man's affection is beyond words. He doesn't really care what Qianyang's ability is, as long as it is Qianyang's, he likes everything.

At this time, Zixuan's cell phone rang suddenly.

"Sorry, I'll take the call."

Zixuan ran to the side to answer the phone. It turned out that it was Teacher Wang Yefei who informed her that all the equipment she customized had been completed and had been shipped to the school, and asked her when she would assemble them and experiment again.

Zixuan told Qianyang the content of the phone call and asked Qianyang's opinion. After all, the experiment was meaningless without Qianyang.

Qianyang thought for a while, and asked if he could do it here, just to let his grandpa take a look.

Zixuan felt that it didn't matter, so she asked Teacher Wang Yefei to take the trouble to send the equipment here.

About an hour later, the girls were happily feeding the koi by the lake. Wang Yefei arrived, and Jiang Chanji went out to help her bring in a big box.

"I'm sorry, Mr. Wang, because my waywardness has troubled you." Qian Yang apologized.

"It's okay, I just want to watch your experiment, and besides, it's the weekend, so it's not class time." Wang Yefei waved her hand generously.

Qianyang introduced Wang Yefei to her grandfather again. While the two were greeting each other, Zixuan opened the box in the gazebo, took out all the equipment inside, arranged them neatly one by one, and checked whether the size and weight were as expected.

Jiang Chanji squatted aside curiously. These dazzling equipment looked very advanced, and he couldn't guess what they were used for.

"Come on, Qianyang, try to see if it sinks." Zixuan greeted.

Qianyang trotted over, and the other girls also finished playing and came to watch.

What Zixuan pointed to was a long cylindrical metal tube, about 80 centimeters in length and about [-] centimeters in diameter, made of silver-gray titanium alloy, with a buckle on each end, and a strap connecting the two buckles .

"Is this...back?" Qianyang asked.

"Yes, try the weight on your back." Zixuan said.

Qianyang carried the metal tube behind her back, and adjusted the length of the strap a little. It looked like a painting tube used to hold drawing paper that students of art often carry behind their backs.

"It's a bit heavy, but it's okay." Qian Yang said.

"That's fine, but it won't be so after putting these parts in." Zixuan said.

The old man stared at the equipment and parts on the ground, gradually showing surprise, "This...the gold-plated concave total reflection mirror, internal and external electrodes, gas storage pipe, air return pipe, folding mirror, cooling water circulation system... Do you want to make a carbon dioxide laser cannon? "

Qianyang's grandpa broke Zixuan's intention straight away, which made Zixuan very surprised, and even more surprised was the other people present. No one thought that Zixuan's shot would be such a shocking weapon!

"How did you recognize it?" Zixuan asked curiously, at the same time admitting that what she was going to make was indeed a carbon dioxide laser cannon.

On the wrinkled face of the elderly, the skin loses most of its moisture and collagen when it was young, and becomes dry and loses its elasticity.He suffered from kidney failure for several years. Although Mei Yibai saved his life, the illness came and went like a mountain, and the vitality in his body seemed to be sucked out, and he was no longer what it used to be. And this kind of him suddenly had a strange look on his face, and said proudly: "Because I have seen similar things before, although the shapes are different, and the sizes are even different, but I will not see them when I see them." Forget, if you want to be successful in business, you don't just need to eat and drink..."

Zixuan recalled a bit, thinking of his resume, among the dozens of companies under the business group he manages, there is a company that has close business cooperation with the army. I think the army has tried to produce something similar, but I have never heard of it. The following, probably encountered technical difficulties and stopped.

"What? Zixuan, do you really want to use these equipment to make laser cannons?" Jiang Chanji asked in disbelief, no matter how you put it, it's too sci-fi.

"The principle of the carbon dioxide laser cannon is very simple, and the body is also very simple. Anyone with a little hands-on ability can buy materials online and DIY. The most complicated thing is the power supply. The power supply capacity limits the application of the laser cannon. Weapon-grade carbon dioxide laser cannons have 90% The above weight and volume are wasted on the battery, power supply system and transformer.” Zixuan said, turning her head to look at Qianyang, “But Qianyang-senpai is a natural mobile power supply, which can output extremely high voltage. It solves the biggest problem of using laser cannons in actual combat."

"As for Senior Sister Xiaosui and Senior Sister Aurora, after Senior Sister Qianyang finishes firing the laser, they can help the laser cannon to cool down quickly by accelerating water circulation and powerful cooling, so as to shorten the interval between the next laser beam."

"If Senior Sister Xiaosui and Senior Sister Aurora are busy dealing with other enemies and cannot help Senior Sister Qianyang, it doesn't matter too much, but it will take a few minutes or ten minutes before the second beam can be launched. Laser, otherwise the laser cannon will deform the internal optical path due to overheating. If necessary, you can also ask senior sister Aurora to solidify carbon dioxide to replenish the laser cannon...is it ammunition?"

Including Teacher Wang Yefei, everyone was dumbfounded after hearing Zixuan's eloquent talk.

This is almost the ultimate point-kill type long-range weapon. Jiang Chanji's screeching bone bow and Raphael's horn bow are all in the rhythm of being wiped out in front of the carbon dioxide laser cannon!
Of course, just as there is no perfect ability, the carbon dioxide laser cannon is not perfect, it needs a powerful power supply and a powerful cooling device, these additional devices limit the use of the laser cannon, but Qianyang, Xiaosui and Oku The combination of the three abilities of Lola can greatly simplify the structure of the laser cannon, save the power supply, battery and transformer, streamline the cooling system, and almost only keep the main body of the laser cannon, and use new materials regardless of cost, which makes The size and weight of the laser cannon can be greatly reduced, otherwise it has no practical value at all.

In fact, even the cooling water circulation system could have been omitted, but considering that Qianyang may be alone, it is impossible to be with Aurora and Xiaosui all the time, so it is kept at a minimum.

Due to the rush of time, other parts of the laser cannon can be temporarily customized, but the core component of the carbon dioxide laser tube can only use off-the-shelf industrial-grade metal laser tubes, and it is too late to customize. Anyway, the current laser cannon is just a prototype, and it can be slowly developed in the future. Complete.

Zixuan saw that everyone was silent, so she started assembling as if no one was there, and assembled the equipment parts in the titanium alloy cylinder step by step, then checked it again, and installed a A small laser transmitter, just like a laser pointer worth a few dollars, is used for aiming.

Zixuan turned on the laser sight, and a small red dot appeared on the ground pointed at by the sight.

"Okay, it should be almost done, Qianyang, come and try?" Zixuan introduced, "The method of use is very simple, no matter whether you are holding the laser cannon, carrying it on your shoulder, or wherever you put it, you can use it. , just remember, wherever the red dot falls, that is the target of the laser emission, don’t use it on people lightly.”

There is also a handle on the side of the cylinder for easy holding. The outer shell of this handle is made of iron-cobalt alloy, which is always connected to the electrode inside the laser cannon.The handle is collapsible and folds down when not in use, out of the way.

There is no such thing as a trigger, because as long as Qianyang activates the ability, the electric energy generated by the iron-cobalt alloy will go straight to the inside of the laser cannon, and ordinary people holding this thing in their hands are no different from scrap iron.

Qianyang is not a boy who likes to wield knives and guns since he was a child. He has no interest in weapons, and he is a little afraid. Suddenly, she is asked to operate this laser cannon that she has never seen and has never been used before. She feels frightened. , I dare not step forward.

"Can I try it?"

Teacher Wang Yefei stood up.

The way of using the abilities of electric supernatural beings has always been the biggest problem for them. They have thought of many ways, most of which are relatively simple, such as enhancing the hit rate of electric arcs, but no one has ever thought of using their own abilities. Electrically powered laser weapons.

If she can also use this laser cannon, even if it can only be fired once every ten minutes, it will be a great benefit.

"Yes." Zixuan nodded.

Wang Yefei picked up the laser cannon and tried several ways to hold it. Due to the girl's weak strength, it was very uncomfortable to hold it in her hand or under her armpit. In the end, she chose to carry it on her shoulders.

Everyone hurried to her side, for fear that she, who is not familiar with the operation, would accidentally trigger the laser and make a hole in herself.

"What should I try to use as a target?" She herself was also very careful, always avoiding directing the front of the laser cannon at people.

The front of the laser cannon is protective glass. There are two layers of glass, one is the inner layer and the other is the outer layer. The outer layer is a fully enclosed special glass with high strength and high light transmittance to prevent water and dust from entering. A circular hole is left, and the laser is shot out from the circular hole.

"How about that tree, or that rock?" The old man pointed to a rockery facing the artificial lake. Beside the rockery were weeping willows and large bluestones.

"If something in your house is damaged, the school will compensate you according to the price." Wang Yefei aimed the laser cannon at the willow tree, and the red dot laser shot from the sight had already landed on the tree trunk.
