Black Silk Female Police Detective Exorcist

"I already told you, Youyou, you've been misled by the public's incorrect perceptions~~"

Qin Huanyu smiled and comforted her:

"Even I, who always talk about pursuing scientific rigor, have been using units of mass as units of weight all along. You just happened to not notice this misconception, don't worry about it."

"A misconception, huh... okay."

Yi Youyou sighed with a wry smile, then thought for a moment, and doubt reappeared in her eyes:

"By the way, Ayu, what about when I add weight to my projectiles for ranged attacks? At that time, I throw the projectiles horizontally, so it shouldn't count as manipulating the gravity coefficient, right?"

"So, Youyou, your ability is [coefficient manipulation]. The coefficients you can change are not just the gravity coefficient, but almost all the coefficients involved in classical mechanics."

Qin Huanyu gently shook her finger and continued to explain:

"Although the formulas for calculating gravitational potential energy and kinetic energy are different, many of the principles are the same. For example, their two most important variables are mass and velocity (acceleration). The only difference is the calculation method of the formula. In addition to the two variables of mass and velocity, the remaining fixed values ​​in the entire formula can be summarized as coefficients."

"Youyou, when you change the weight of an object, you are essentially increasing the force that the object generates toward the Earth's center while keeping its mass and gravitational acceleration constant."

"If you can do that, you can naturally manipulate the kinetic energy formula to make the kinetic energy generated by the thrown object, even if the mass and speed are normal, extremely abnormal... because the kinetic energy of an object is also directly mathematically related to its force. If the force is abnormal, the kinetic energy will naturally be abnormal as well. And you rely on this abnormally powerful kinetic energy to attack the enemy."

"It's easy to verify this. Just use quicklime and water to do the experiment. Youyou, you can throw the quicklime block that has been affected by the power horizontally into the water and see if there is any change in the chemical reaction between the two. That will tell you whether the quality of the quicklime has really changed."

"..."

Yi Youyou remained silent for a long while before sighing and gently shaking her head:

"There's no need to continue the experiment. I believe in your abilities, Ayu, and I trust your conclusions."

After saying that, she quickly composed herself and asked curiously:

"Will figuring out the truth about my abilities help in developing the uses of my superpowers and creating my own unique equipment?"

"Of course it helped, and it helped a lot."

Qin Huanyu clearly already had some ideas and plans, and smiled, shaking her head:

"Youyou, since you can make the things you throw very heavy, like launching super-heavy marbles, you should also be able to make the objects very light and throw them very fast, right?"

"Of course you can. In fact, I've developed my own way of using this capability before."

Yi Youyou nodded:

"But the effect was not ideal. No matter how light I made the projectile, it was difficult for me to exceed the speed of a pistol bullet when I threw it... because the lighter the projectile, the greater the air resistance it is affected by. In the end, its power was not as good as your small-caliber police pistol, and it was far inferior to super-heavy marbles. So I quickly gave up on this approach."

"Then you can go back to this path in the future. The weapon I've tailored for you is designed around the way you use your abilities. It will be a very powerful weapon, and I can also incorporate a few other functions that suit you."

Qin Huanyu smiled confidently:

"Youyou, spend the next few days practicing how to use this ability again. Also, give me that top-grade Wind Control Pearl you got from the Royal Treasury a while ago. In a few days, I'll definitely give you something that will satisfy you."

"...Hmph, what a wicked thing, always trying to suspense and pique people's interest."

Yi Youyou pouted and poked Qin Huanyu twice with her finger, but still satisfied Qin Huanyu's desire to show off. She didn't press the issue and even gave her the top-grade Wind Control Pearl.

For the next eight days, Yi Youyou did not see Qin Huanyu again. Qin Huanyu completely locked herself in the workshop and did not even go home to sleep.

Yi Youyou felt a little lonely, but she didn't waste any time. Instead, she followed Qin Huanyu's instructions to practice using her abilities, trying to make the objects she affected as light as possible and maintain that effect for a period of time after she released them.

She was already very talented, and now with hard training and guidance from a professional team, the results after just a few days are very obvious.

By changing the mechanical coefficients, Yi Youyou can now throw steel balls with a diameter of about 10 millimeters at a speed of 2 to 3 Mach. This is still affected by air resistance. The speed would be even faster in a vacuum environment.

It was at this moment that Qin Huanyu walked out of her workshop. The special weapon she had tailored for Yi Youyou was finally completed.

From the outside, this special weapon looks like a large silver women's parasol, with a diameter of about 0.8 meters when opened. There is also a round decorative inlay at the end of the umbrella handle, which is Yi Youyou's top-grade Wind Control Pearl.

After receiving the silver parasol, Yi Youyou first opened and closed it a few times, then examined it from all angles before nodding.

"This umbrella is quite pretty... but what about its effects? I don't see any of the powerful weapon you mentioned at all."

"I'll tell you about its attack capabilities when we get to the test range. Let me tell you about its support and defense capabilities first."

Qin Huanyu smiled, clearly intending to keep Yi Youyou in suspense, and pointed to the exquisite Wind-Controlling Pearl at the end of the silver umbrella handle:

"First, here it is. It's a very simple design. You just need to open the umbrella and inject spiritual energy to activate the Wind Control Bead. This will generate an updraft... Combined with your ability to change your weight, which you're already very skilled at, you can fly even when there's no wind at all."

"Hmm, this function is not bad. The reason I chose this top-grade Wind-Controlling Pearl in the Royal Treasury was so that I could fly even when there was no wind."

Yi Youyou nodded with satisfaction, then shrugged.

"It's just that I don't have the multi-threaded thinking of you, so changing my weight and controlling the Wind Control Bead at the same time is a bit difficult for me. Now this umbrella can fix the direction of the airflow generated by the Wind Control Bead, which makes my operation much easier."

"That's exactly what I noticed, which is why I designed this specifically... How about it? Aren't I thoughtful? My darling Youyou, do you want to give me a kiss as a reward?"

Qin Huanyu immediately put on a self-satisfied expression and deliberately brought her face close to Yi Youyou's mouth so she could kiss her.

At this moment, they were still in the Ling Su Research Institute. Researchers would pass by from time to time. Yi Youyou was a little shy and didn't really want to kiss him, but Qin Huanyu was just being a shameless person who would stay right next to her mouth if she didn't kiss him.

Helpless, Yi Youyou could only give Qin Huanyu a quick peck on the cheek amidst the kind chuckles of the passing researcher.

"Hehe~~"

Qin Huanyu then turned her face away with satisfaction and continued to point to the surface of the silver umbrella:

"The second function is the protective function of this umbrella... It took me nearly four days to develop the material formula for this umbrella surface. I deduced and calculated tens of thousands of possibilities in my mind before I finally found the best formula and ratio and developed this alloy... Hmm, since the name Jade Alloy has already been used, and it was developed for you, Youyou, I plan to name this new alloy Jade You Alloy."

"Jade Nether Alloy...that name sounds a bit corny."

Yi Youyou pouted, but her eyes couldn't hide her happiness, satisfaction, and smile.

"So? What are the effects of this Jade Nether Alloy?"

"First of all, its content of Absolute Spirit Iron exceeds 67%, which has a very good defensive effect against Spirit Element. For example, if you use this umbrella to block Tingxue's Sunflower Water Divine Lightning, you will probably only experience a slight numbness in your hand, and you will definitely not be injured."

Qin Huanyu touched the umbrella surface with her hand, quite pleased with herself:

"Secondly, this alloy is very soft and can even be drawn into fine threads to weave soft armor, so it will not affect the comfort when used as a regular parasol or umbrella."

"After all, apart from the Absolute Spirit Iron, the other rare metals in the Jade Nether Alloy formula are all very expensive. Gold is the cheapest of them all... If the Jade Nether Alloy used to make the umbrella canopy were sold, it would be enough to easily buy several large houses in the capital."

"Is that so...hehehehe~~"

Yi Youyou became more and more satisfied as she listened, and soon she was also touching the silver umbrella and grinning foolishly, causing the passing researchers to look at the silly couple with disapproving eyes.

With a faint smile, Qin Huanyu and Yi Youyou finally arrived at the test range. This was a special testing ground used by the Lingsu Research Institute for Qin Huanyu to test her abilities and various new inventions. It had excellent protective capabilities and could withstand the explosion of a 1000-pound aerial bomb. There were also a pile of steel plates in the range that could be used to test the power of attacks.

"Finally, there's the umbrella's offensive capabilities."

Qin Huanyu stopped keeping her in suspense and began to formally introduce the main function of the silver umbrella.

She first pointed to the middle of the silver umbrella's handle, where there was a hidden mechanism. When opened, it could be loaded with bullets, like the chamber of an old-fashioned rifle, or steel balls of similar size.

"You should be able to tell from here that it's a dual-purpose gun. It can be loaded with regular rifle bullets and fired via a primer. It can also be loaded with steel ball bullets and fired using the wind pressure provided by the Wind Control Bead."

"Hmm, it's a very simple design. I've seen it on many special agent weapons. Disguising firearms as umbrellas is a common practice in special agent weapons."

Yi Youyou nodded, still somewhat puzzled:

"But Ayu, the special weapon you tailored for me must be more than just this, right?"

"Actually, it's not too complicated. If this umbrella were in someone else's hands, it would just be an expensive umbrella gun. But it's different in your hands, Youyou. So it's your exclusive weapon."

Qin Huanyu once again revealed a smile that piqued everyone's interest:

"No matter how much I say, nothing is as intuitive as you trying it out yourself, Youyou... In a moment, Youyou, you should first infuse the bullet with your abilities, which is what I mentioned before, to make the bullet as light as possible, and then use the umbrella's gun function to shoot the target."

"That's...ok."

Following Qin Huanyu's instructions, Yi Youyou quickly infused a bullet with her own power, then loaded it into the umbrella handle, held the closed parasol horizontally, and aimed at the target about 200 meters away in the shooting range—20 steel plates stacked together—like using a rifle.

"This won't do!"

Just as Yi Youyou was about to fire, Qin Huanyu suddenly hugged her waist and brought his mouth close to her ear:

"The power of this gun will definitely exceed your expectations. You need to hold it firmly and stand still, and treat it like a cannon, not a gun."

As she spoke, Qin Huanyu held Yi Youyou's hand, letting Yi Youyou lean her entire weight on her, before gently twisting the umbrella handle.

Bang!

A loud bang and a huge recoil occurred at the same time, and Yi Youyou was surprised... If Qin Huanyu hadn't been holding her from behind, she might have actually fallen on her butt.

The recoil was so great that the shot was extremely powerful. The bullet traveled at an incredible speed after leaving the barrel, and almost immediately began to burn violently due to friction with the air. When it hit the steel plate that was the target, it turned into a small fireball that easily burned through two layers of steel.

Yi Youyou was shocked, but Qin Huanyu was clearly not satisfied:

"Ordinary bullets really don't work. The copper bullets are too fragile. They lose their kinetic energy and lethality after being melted by the high temperature halfway through the journey, leaving only pure high-temperature attack... It's clear that we still need to use special bullets."

As she spoke, Qin Huanyu had already reached into the side pocket of her white coat and pulled out a bullet whose material was clearly different from ordinary bullets:

"Try this one, Youyou. It's a tungsten steel bullet that I made myself. It should be able to unleash the full power of your special weapon."

"Uh... well."

Yi Youyou swallowed hard. She was a top student who graduated from Shendu University. Although her physics grades were not as good as Qin Huanyu's, they were still very good. She could already roughly imagine how terrifying the true power of her special weapon strike would be.

After reloading and replenishing the bullet's power, Yi Youyou was completely focused during her second shot. She even increased her weight to reduce the impact of recoil and chose to lie prone to fire.

Bang!

After another loud bang and a huge recoil, Yi Youyou's shot was more powerful than any single-person firearm, almost comparable to a small electromagnetic cannon.

The 20 steel plates used as targets were mostly penetrated, the last few that weren't penetrated were severely deformed, and the first few were completely torn apart by the enormous kinetic energy.

"...That's amazing!"

Even though she had some idea of ​​what was going on, Yi Youyou was still dumbfounded when she saw this scene with her own eyes. This kind of power had surpassed the trump card ultimate skills of most patrol envoy level experts. Even top experts would be injured or even killed if they were careless.

"Ayu, how did you do that?"

After standing up from the shooting position, Yi Youyou asked with considerable curiosity.

"Hmph, it's very simple."

Qin Huanyu, of course, wouldn't let such a good opportunity to show off pass by, and once again shook her head and swayed her head:

“During our battle when we were choosing the princess, when we fought that octopus-headed bishop together with the palace, I noticed something… that the marbles whose weight you altered with your ability would regain their weight after touching the Absolute Spirit Iron. You know that yourself, right?”

"Ah."

Yi Youyou nodded:

"The effect of the power I infuse into an object will disappear quickly after it leaves my hand, and it will usually return to its original weight within a few seconds... Touching the Spirit-Absolute Iron will make this process complete instantly, so I am relatively powerless when facing the Spirit-Absolute Iron defense."

"Hehe, I used this to my advantage, which is why the bullets you fired, Youyou, have the power of an electromagnetic cannon."

Qin Huanyu continued to smile smugly:

"As I explained before, Youyou, the essence of your ability is to manipulate coefficients. That is to say, when an object infused with your ability touches the Absolute Spirit Iron, the coefficient will be restored, but its mass and speed will remain unchanged. It's just that the coefficient is lower, so the force will be reduced, turning what should be a powerful and heavy marble into a mere scratch."

"That's why I had you practice using your reverse ability more recently, Youyou... If you can make the bullets very light through your ability, then whether it's the primer or the wind pressure, wouldn't you be able to make the bullets fly many times faster than normal bullets?"

"In this situation, if the bullet traveling at supersonic speed were to come into contact with the Spirit-Absolute Iron, wouldn't the bullet's coefficient be restored, and its kinetic energy be greatly increased, instantly upgrading its power from that of an ordinary rifle to that of an electromagnetic cannon? What do you think? Isn't that a brilliant idea?"

"...So that's it."

The principle was not complicated, and Yi Youyou understood it immediately.

She quickly checked the tip of the umbrella, and sure enough, more than 5 centimeters of the barrel at the tip was made of pure spirit iron. The bullets she fired were able to come into contact with the spirit iron before leaving the barrel, which restored their coefficient and gave them extremely strong kinetic energy and lethality.

This is also why the silver umbrella became Yi Youyou's exclusive weapon, because only in Yi Youyou's hands can it unleash power comparable to an electromagnetic cannon. If others use it, it will at most be a strangely shaped and ridiculously expensive single-shot rifle.

Another point is that the tungsten steel bullets fired in this way are no longer considered supernatural attacks, but purely physical kinetic energy attacks, and will not be countered by the Spirit-Slaying Iron!

If Yi Youyou had had this exclusive weapon during the battle in the back garden of the palace, she could have easily destroyed the Octopus Archbishop's Soul-Slaying Iron Body!

It's never too late to mend things. If anyone thinks they can bully Yi Youyou because of her Spirit-Slaying Iron defense, Yi Youyou can give them a bullet and let them experience a surprise.

Afterwards, Yi Youyou enthusiastically test-fired several more shots, and the power of each bullet was very consistent.

She is very satisfied with this new signature weapon.

Have you named this umbrella yet?

After the test shot, Yi Youyou casually asked, and before Qin Huanyu could answer, she herself pouted in disdain:

"It should have been named by now, right? With your naming style, how about Jade Umbrella?"

"Hey...hehe."

Qin Huanyu smiled somewhat awkwardly:

"I think this name sounds pretty good, and it's also very meaningful... Of course, if you're not satisfied, you can press F2 (rename) it."

"...Whether it sounds good or not is another matter, but this name is indeed quite meaningful, after all, it was personally crafted and given to me by you."

Yi Youyou thought for a moment and said:
