Zheng Rui was next to her, holding a single pendulum and watching Zuo Youcheng "cast spells", but she waited for 15 seconds, 30 seconds...... 1 minute ...... 2 minutes ......

"Ahem, classmate, can you do it?" Zheng Rui finally couldn't help it, it took more than two minutes for the ability to activate, how could it be used?

"Don't talk, it'll be fine right away-" Zuo Youcheng said with a serious face, "just a little bit ......"

He seemed to be pushing something with the "Force", and Zheng Rui didn't dare to say that it was faked. Maybe that's how cumbersome this ability is to activate, it's high-tech after all.

Zheng Rui put away the pendulum and put the lollipop swing ball into the pocket of her jeans.

As soon as she put the swing ball away, she heard a very subtle "bang" sound from all directions, and then Zuo Youcheng opened her eyes and said happily: "Ah, okay! ”

This is followed by a feeling of weightlessness.

Zheng Rui pulled her pendulum out of her pocket and gently flicked the pendulum ball with the rope.

Left.

Right.

Left.

Right.

……

She recorded the time of 20 cycles, and with a solar calculator, the cycle was about 20% faster than the normal pendulum period at the g-value, which means ......

The strength of gravity in the range of Zuo Youcheng's "cast" spell is approximately equal to about 70% of the normal gravity strength.

The effect is quite significant.

Zheng Rui was surprised, this ability is obviously not a chicken rib, it can reduce the g-value by 30%, which is equivalent to increasing the take-off height of our team by almost half in battle, or reducing the friction of the enemy by 30%, even if it is not in battle, reducing the weight of materials by 30% is quite a powerful buff.

The downside is the long preparation time, which is a fatal drawback, but according to the logic of ability evolution, it's not something that can't be improved.

However, there is also the problem of distribution.

Now Zheng Rui is measuring the pendulum period next to Zuo Youcheng, but if he were measured farther away, would the results be different? Zheng Rui had guessed that this would conform to the Gaussian distribution, but now she didn't even know the shape of the ability's range.

"You keep moving, I'm going to set a few points to measure the pendulum cycle." Zheng Rui instructed Zuo Youcheng, and then quickly drew three equidistant concentric circles in the experiment notebook, and asked, "Do you estimate how big your range of gravity change is?" ”

"I don't know...... My brother said there are ten meters? Zuo Youcheng scratched his head.

"Ten meters? It's big enough. Zheng Rui couldn't help but remember that when she took shooting class in her sophomore year, there was only one black circle left in the black circle of the target ten meters away.

Then add another circle and set the radius of the measuring point at 2.5 meters, 5 meters, 7.5 meters and 10 meters.

In order to determine the shape, find four points in each circle during the preliminary measurement, and record 20 cycles at a time, which should be enough.

——

In the end, it was determined that the gravitational field should change in a circle - or spherical, but the projection of a sphere in three-dimensional space on the ground was circular - and the distribution of the change intensity was not a Gaussian distribution centered on Zuo Youcheng, but the highest percentage of gravitational change on a ring with a radius of about 10 meters, about 0.5 times the gravity, decreasing to about 30% along the radius to the center, and attenuating to zero within 2.5 meters along the radius.

Obviously, it is a skewed distribution, and Zheng Rui can't think of how to calculate it for the time being, but several points can be preliminarily determined as effect detection indicators: the center point (radius of 0 meters), the 1/2 radius point (radius of 5 meters), the upper point of the ring (radius of 10 meters) and the outer point of the ring (radius of 11 meters).

Zheng Rui intuitively speculated that after the evolution of this spatial ability, not only should the "cast" speed be increased, but the specificity of this ring distribution should also be improved to a certain extent. Since this skill is set to be the highest on the ring with a radius of 10 meters, it is reasonable to guess that if you can skillfully cast the ability, the gravitational change effect should be the same in the area within a radius of 10 meters, and the change effect will decay quickly outside the 10 meter radius, otherwise what is the use of drawing this circle?

After counting the three-page formula, Zheng Rui closed the experiment notebook with satisfaction.

Next to him, Zuo Youcheng watched the whole process curiously, and then asked: "Big guy, you have been counting for so long, what is the conclusion?" ”

Zheng Rui herself understands it quite well, but she can't understand it when she tells others, she subconsciously thinks that Zuo Youcheng will know the effect of her ability, and just said in general terms: "The peak of the effect of your ability is on a ring with a radius of 10 meters, and the attenuation inside the ring is slow, and the attenuation outside the ring is rapid." Now you keep training, and tomorrow I'll test your ability distribution again and see what happens. ”

Zuo Youcheng didn't quite understand what she said, but in comparison, he was more concerned about training: "Hey, how should I train?" ”

"You're ...... Cast spells repeatedly. Zheng Ruixue made a gesture of raising his hand, "You're too slow to release the ability now, if it's still so slow in the future, this ability is no different from nothing." ”

"I think it is, too, and it's not just slow, it's slow." Zuo Youcheng said nonchalantly, "I have succeeded once before this. If it weren't for the long time I was idle, I almost thought this thing wouldn't be able to go. ”

"It's okay, you just know how to let it go now." Zheng Rui patted him on the shoulder again.

Zuo Youcheng is indeed a bit second, but Zheng Rui feels that if she encounters this in her sophomore year of high school, there is a high probability that it is not as good as Zuo Youcheng. Gamifying everything around her because she was afraid, like her, sticking to her assumptions about survival games and avoiding thinking about what would happen if the game failed......

"By the way, big guy, what's your ability?" Zuo Youcheng asked with some curiosity.

It sounded like he really didn't know that Zheng Rui was immortal, or maybe they hadn't heard of an ability type like immortal at all.

"Didn't you say I was a psychic?" Zheng Rui vaguely gave him the question.

"But...... Your physical attack is too strong, it doesn't look like a pure mental type. Zuo Youcheng muttered, "My brother's mental type is so weak, and this individual difference is too big, right?" ”

Fang Tong's situation is really chicken.

If it was really an alien species that originally used consciousness connections to communicate information that designed this ability, it would be useless for humans. Zheng Rui couldn't help but want to complain, is this the consequence of the development of the game without internal beta testing?

However, for Zuo Youcheng, Zheng Rui felt that it would be enough to blind him a little, so he said casually: "That may really be an individual difference." ”

"yes, I'll just say my brother is too weak." Zuo Youcheng continued to say poorly, "But it's not necessarily, you only have the ability to work after giving human blood, which means that the spiritual type thing still has to have a medium?" I can let my brother try it when I go back......"
