Since mass effect and gravitational force are all related to space-time-gravity-mass, there are many commonalities in the corresponding algorithms.

For low-order abilities, only the inertial frame equations under classical mechanics need to be considered; Higher-order applications need to be extended to the relativistic background to calculate the temporal and spatial distributions under the gravitational field equations.

After all, gravity is a geometric representation of time and space, and the distribution of time and space depends on the mass distribution. That is to say, from the mass effect ability algorithm, we can deduce the gravitational ability algorithm with the help of the physical relationship between matter-space-time and space-time, and space-time-gravity.

To put it simply, as long as you get the Xingjia algorithm, there is a high probability that the Chengjia algorithm can be derived.

That way, he can start learning about gravity!

After listening to Cheng Jinyang, Xing Yuanzhi sighed with emotion.

For her, the various algorithm resources in the Hejian Xing clan are completely demanded, so it is difficult to understand the urgent desire of Cheng Jinyang for algorithms, even without thinking:

"There's no need to deduce, I also know people in the Shendu Cheng clan, so I'll just give you the low-level algorithm."

Cheng Jinyang: ???

Well, I still underestimate the energy that this eldest lady of the family possesses.

So the two hit it off:

Xing Yuanzhi is responsible for helping Cheng Jinyang control the gravitational ability, and Cheng Jinyang allows Xing Yuanzhi to live in his house.

At first glance, it seems that the man takes advantage of it, and the woman has no brains to post it, but there is actually an ulterior purpose in it, and it is not a simple relationship that can be explained in a few words.

After the matter was settled, the two of them realized that it was still less than half past four in the morning, and they couldn't help but feel a little sleepy.

"Where's my room?" Xing Yuanzhi stood up and asked indifferently.

Now that the interest agreement has been reached, she will no longer force a smile and maintain a friendly posture, and her innate cold temperament will return immediately.

"Why don't you just stay in the master bedroom?" Cheng Jinyang suggested.

The old house left by my parents is probably four bedrooms and one living room. The four bedrooms are the master bedroom (parents), the second bedroom (the eldest son Cheng Jinyang), the second bedroom (the expected second child) and the study.

Since the parents had not yet had time to have a second child, the second bedroom was completely unfurnished and empty. Since Xing Yuanzhi wants to live in, excluding the first second bedroom that Cheng Jinyang currently lives in, only the master bedroom of his deceased parents can be released.

Pulling open the door of the master bedroom, Xing Yuanzhi's face immediately changed - she smelled the heavy smell of dust in the room.

"Change rooms." She couldn't help but say the truth.

"That'...... You live in my room, and I go to sleep in the living room? Cheng Jinyang was embarrassed.

Although it was a little aggrieved to give up the bedroom, considering that after all, I still had to get the gravitational algorithm from her, so I could only give in for the time being.

So Xing Yuanzhi came to Cheng Jinyang's room, took a look at the messy beds of adolescent high school boys, and the bloated quilts piled up next to them, and showed an undisguised expression of disgust.

"Go buy me a sleeping bag." Xing Yuanzhi said.

"It's four o'clock in the morning......"

"A thousand dollars, more is yours." Xing Yuanzhi took out her mobile phone.

"Okay." Cheng Jinyang sighed.

Xing Yuanzhi swept his face with his mobile phone, and then opened an intimate payment to the other party, with a limit of 1,000 per month.

Cheng Jinyang also looked at his phone and asked:

"Does this amount count in the monthly relief fund of 15,000......"

"If you're back in ten minutes, it doesn't count." Xing Yuanzhi replied coldly.

So Cheng Jinyang rushed out.

Turning her head, Xing Yuanzhi looked at the environment in the room, her delicate and beautiful brows furrowed tighter and tighter, and they were almost tangled.

Oh my God, how can this boy's room be so dirty!

She crouched down on her knees, looking at the small amount of hair, dust, and lint looming on the floor, and she felt an instinctive urge to vomit and go crazy.

After hesitating for a long time, Xing Yuanzhi finally got up and went to the bathroom to find towels, brooms and mops.

When Cheng Jinyang returned home, he saw that Xing Yuanzhi had tied up her loose hair at the back of her head, wrapped her mouth and nose with a towel, and was cleaning the floor of his room with a mop.

Inexplicably, I felt relieved to see my wife cleaning when I came home......

"Your room!" Seeing Cheng Jinyang coming back from outside, Xing Yuanzhi, who was furious, rushed over, ripped off the towel on his face and shouted, "How can it be so dirty?" Are you a pig, why do you make the room like a pig's nest? Do you never clean it? ”

"I clean my room once a week." Cheng Jinyang was inexplicable, and the original good impression of her disappeared again.

"Huh?" Xing Yuanzhi showed an incredulous expression of "No", "This is the room where you sleep!" Cleaning once a day in the morning and evening isn't too much, right? With so much dust and lint on the floor, can you sleep? ”

"I'm not sleeping on the floor." Cheng Jinyang said lightly, lifting the bag in his hand, "Your sleeping bag is brand new." ”

"Because I'm going to sleep on the floor!" Xing Yuanzhi shouted.

"Why?"

"Do you want me to sleep in your bed?" Xing Yuanzhi asked him rhetorically, "Can you accept others sleeping in your bed casually?" ”

"Why can't you accept it?" Cheng Jinyang asked subconsciously, and then looked at her and his gaze became wrong:

"Hey, Zhi, are you supposed to ...... Is it a habit of cleanliness? ”

"I love to be clean." Xing Yuanzhi also calmed down and denied it, "Also, don't call me Ah Zhi." ”

"Okay, Zhi. How many times a day do you have to shower? ”

"Of course, wash it once after eating." Xing Yuanzhi looked at him with an irritated expression, "I said don't call me Ah Zhi." ”

"I see, it's really cleanliness." Cheng Jinyang sighed, "It seems that my family's water bill is going to explode this month." ”

"I'll pay for the utilities." Xing Yuanzhi stared at him for a long time, and suddenly said, "You...... When you come back from outside, you don't change your clothes? ”

"Huh?"

"Dust." Xing Yuanzhi said with a disgusted expression, "You will bring dust to the house like this." ”

So Cheng Jinyang could only take off his coat and throw it on the chair near the door, wondering if he could hold on until the day when the other party got the ability algorithm - although this girl is very good-looking, her living habits are too perverted, and living with her is a nightmare.

But living alone anyway is a nightmare every day, and the ability to resist pressure in this area is not weak, so it doesn't matter.

Xing Yuanzhi cleaned up the room here, and then went to the bathroom to take a shower. Due to the hurry when I came, I didn't even bring a change of clothes, so I had to endure the unhappiness and put the dress back on.

When I walked out of the bathroom, I saw that the time on the wall pointed to 5 o'clock in the morning, and it was already dark outside.

Cheng Jinyang was lying on the sofa and sleeping, his expression involuntarily showing a look of pain. Xing Yuanzhi squatted down beside him and stared at his face in silence.

So, is it you......

She hesitated and stretched out her hand, and from a distance, silently felt the strength of Cheng Jinyang's spiritual field.

The spirit field, similar to the biomagnetic field, is an outward representation of the strength of the person's own bloodline. Abilities can roughly judge how many grades the strength of each other's bloodlines is located by sensing the strength of each other's spiritual field...... Of course, the specific combat strength depends on the calculation power.

At this time, under Xing Yuanzhi's perception, Cheng Jinyang's spiritual field was slightly weaker than his own, but not much, so there was a high probability that it should be "Nine Grades".

However, the strength of his spiritual field was not stable, but was periodically going up and down violently, which was completely beyond Xing Yuanzhi's cognition!
