Jiankang City, a huge science and technology city.

Even if Cheng Jinyang has lived here for more than ten years, it is still difficult to get a full picture of it.

At 5 o'clock in the afternoon, follow Xing Yuanzhi to take Metro Line 2, get off at "Xinjiekou" station, turn left and right in the bustling underground commercial street of the complex, Cheng Jinyang couldn't help but ask:

"Ah Zhi, why do you still wear a hat when it's underground?"

"Because the underground tunnel is not ventilated, there is more dust floating in the air, and the hood can block it." Xing Yuanzhi said indifferently, "And if you dare to mention the word 'Ah Zhi' again, I will kick you under the subway track immediately." ”

After passing through various bustling shops, the two found a shop with a sign of "Live Shooting Simulation" at the remote end of the underground street.

The door of this store is crowded, and there is no light in it, so it looks a little infiltrating. There was a robot standing in the doorway, the most old-fashioned model, repeating the sound of "Welcome".

"I booked a shooting range in the morning, and the cost was deducted from my account." Xing Yuanzhi approached the robot, and her white-gloved hand pulled the ID card out of her chest pocket.

"Welcome, Miss Xing, good evening." The robot that glanced at the ID card was still talking mechanically, and suddenly spat out a small ticket from its mouth.

Xing Yuanzhi took the small ticket and motioned for Cheng Jinyang to follow.

Passing through a dark, lightless passage through the doorway and finding the predetermined shooting range, the room suddenly opened up and was well-lit.

Various types of firearms and ammunition are placed on the shooting table, and in the distance are four 25-meter target tracks. Xing Yuanzhi pushed the gun aside, then took a bullet and said:

"Didn't you learn the 'Imperial Iron Shot' algorithm in the afternoon? Now use your gravitational pull and manipulate this bullet to hit the target. ”

She adjusted the moving target to a distance of about 10 meters and signaled Cheng Jinyang's ability to use.

"Uh, how do you use it?" Cheng Jinyang pinched the brass bullet and asked.

"Just use the ability according to the formula." Xing Yuanzhi said, "The essence of your Cheng family's gravitational ability is to adjust the direction of the gravitational vector, of which the Iron Shooting algorithm has three formulas. You use the first equation to lock on to the bullet, the second equation to reconstruct the direction of the gravitational vector, the third equation to adjust the vector direction, and then aim at the front target. ”

Cheng Jinyang did as he was told. After about 5 minutes, I felt the gravity of the bullet I was holding changed, and I felt like I was about to come out of my hand.

There is a wonderful feeling of "reciting the Fa Sui", as if as long as you think about it, reality will change accordingly.

Is this what it's called?

He carefully let go of his hand, and saw the bullet naturally accelerate and fly out, and then land on the target, bounce a few times, and make a crisp sound.

"Very good, it seems that there is no problem with your bloodline." Xing Yuanzhi said calmly, "At the Nine Rank Stage, you need to exercise your three abilities. ”

She held up three fingers: "Positioning range, ability accuracy, and duration." ”

"Targeting range, which is the maximum targeting range of your ability, beyond which you can't lock the source of the mass; Precision, i.e. how fine you manipulate the direction of the gravitational vector, determines whether you can accurately hit a target farther away than it misses or misses it; Duration, which refers to how long your ability can remain on an object. ”

"Wait." Cheng Jinyang asked strangely, "Why is there no 'power' in the three elements?" After all, isn't the measure of a person's ability by how lethal his ability is? ”

"Hmm." Xing Yuanzhi was noncommittal, "So what do you think determines the lethality of your ability?" ”

"Uh...... Kinetic energy? ”

"That's right, kinetic energy." Xing Yuanzhi nodded and said, "Our mass effect, and your gravitational pull, are mainly used in military applications to inflict damage by amplifying the kinetic energy of flying objects, such as bullets and artillery shells. The kinetic energy of an object depends on the mass and velocity of the object. ”

"The heavier, faster the object, the more lethal it can be. Since your ability is to adjust the direction of the gravitational vector, you can't essentially increase the magnitude of gravity, so you can usually only extend the acceleration distance. ”

"Imagine a vase falling from the second floor and you would normally be able to catch it; If you fall from the twentieth floor, the result of you picking it up with your hands is most likely to be a broken hand. ”

"In other words, the longer the distance and the longer it is accelerated by gravity, the greater the kinetic energy of the object itself, and the more lethal it is."

"I see." Cheng Jinyang nodded, "So if I want to use gravity to manipulate objects to smash people, I have to try to widen the distance, reserve enough acceleration distance for the object, and try to increase its kinetic energy." ”

"That's right." Xing Yuanzhi replied, "The distance is far away, and whether you can successfully hit the enemy will test your ability, accuracy, and duration. ”

"If the accuracy is insufficient, the object you manipulate will easily lose accuracy and miss people after flying over a long distance; If the duration is not enough, and the object is halfway through the flight, the ability disappears and falls, so there is no need to talk about lethality at all. ”

"As for the positioning range, beginners are used to touching with their hands and relying on physical contact to locate the target. I suggest that you directly prohibit yourself from touching the target once you are proficient in using the ability, but instead establish a coordinate system based on yourself in the brain domain, and manipulate the specified object in the distance through calculations. In this way, the ability to activate and use will be more flexible. ”

"I see." Cheng Jinyang thought thoughtfully, "Then again, if you want to increase the kinetic energy of an object, let Ah Zhi ...... It's okay for you to increase the mass of the object, and then I can manipulate it to fly out and smash people, right? ”

"Yes, if you only rely on the gravitational pull of your Cheng family, you can only try to choose heavier objects. However, if combined with the mass effect of our Xing family, then as long as the mass of any object is increased, the kinetic energy can be increased rapidly. ”

Xing Yuanzhi nodded, and then said: "This is also why our Cheng Xing family has been friends for generations, and there is a saying that 'the same qi and branches'...... After all, the cooperation between the two of our two supernatural beings is very amazing. By the way, if you dare to pop the word 'Ah Zhi' out of your mouth, I will immediately pick up a gun and shoot you to death." ”

Of course, this is a joke, considering his special physique, Xing Yuanzhi is reluctant to hit him even if he shoots himself.

However, seeing her pretty face with frost, Cheng Jinyang could only secretly shut down, thinking that if she couldn't be called "Ah Zhi", what should she be called.

Miss Xing? Miss Xing? I always feel a little yin and yang. Yuan Zhi? Eh, how do you pronounce the word "yuan"?

I remember that she reported her name as "yuan" at the beginning.

Scratching his head, Cheng Jinyang continued to try to activate his abilities, trying to keep the three basic calculations firmly in mind.

Seeing him excitedly and constantly activating his abilities, Xing Yuanzhi crossed his arms beside him and silently observed this guy's ability.

The control accuracy is quite excellent, and you can do it for the first time, just like a shooting master who can immediately hit 100 meters and ten rings just after touching the gun, needless to say, talent.

The duration is not discernible, but it is clearly not short, and it has been a long time since the bullet that twisted the gravity was pressed against the target.

Targeting range...... Well, he won't build a coordinate system yet.

It's just that judging from the first two points, this guy's overall computing power is definitely not weak, and with his physique that increases the strength of his bloodline, if he accepts the development of the brain domain in the future......

Xing Yuanzhi suddenly shuddered.

In this way, probably, it seems, there is a chance to reach the peak of the fifth grade?
