Chapter 158: Rules

Du Jia Jia successfully handled the two little cats, and gave each cat a hug, told them to be good, then watched the two cats hop away.

At the edge of sight, Little Yellow still couldn't resist giving the white cat a paw.

Du Jia Jia, returning indoors, received a welcoming crowd from everyone, because most people realized a problem: if she truly could recruit ten or so cats, taking turns coming each day, perhaps later Qiming's security problem could be completely solved.

"Should we also give the white cat a name?" He Ying smiled.

"Ready-made, Little White!"

This name is so natural, as expected.

Thus, Du Jia Jia possessed Little Yellow and Little White as her two great generals, each day busy and happy.

……

Dong Junwei spent far more time on the second cardboard box than the first, because the contents were really quite a lot, and moreover they were all things unrelated to kitchenware.

Two tape measures;

A mouse;

An iron box of tea;

A large roll of wire;

Two hot water bags;

Several pieces of foam plastic used for collision prevention.

This cardboard box looks like it holds some personal items, very messy and disordered, and things like tape measures and wires, even if not separated, even Wei Dalei cannot move them.

But besides the trouble, there is also surprise.

Especially Chen Mu, he is very interested in some of these materials.

First of all is the foam plastic.

This stuff is very light, controlling it should be relatively easy, but the problem is, foam plastic is also called porous plastic, with countless tiny holes in the middle, which is extremely unfriendly for Chen Mu.

But after reaching out and trying.

Chen Mu happily discovered that the difficulty of control was actually far lower than his imagination.

Tang Jing thought for a long time, then said: "This foam plastic, its density is probably around 0.1 g/cm3, but structurally speaking, it should indeed be unsuitable for you to use."

"But it's much easier than I imagined."

Chen Mu separated a piece of foam plastic two or three times larger than his own body, instantly making it into a long strip sofa.

Dong Junwei and others only felt their eyes flash, the speed was incredibly fast.

He Ying touched the white sofa with her hand, then sat down first.

After Wei Dalei plopped down, he happily said: "It doesn't seem as soft as the previous foam plastic."

Chen Mu is making a sofa for the first time, the shape is quite realistic, but the size is not accurate, basically enlarged by more than double, especially the seat height, which is almost as high as a high stool.

Wei Dalei is naturally light, Dong Junwei and Tang Jing's heights are also sufficient, but Zhao Xiao Yan and Du Jia Jia need to jump a little to sit down.

The most troublesome is Gu Yinglong, she chose a spot right next to Wei Dalei; old Wei initially didn't notice, later felt someone pulling his clothes, turned back and saw Gu Yinglong struggling to climb onto the sofa, so he casually lifted her up.

"Because we are currently too light, so we feel the foam plastic isn't as soft as before." Du Jia Jia pressed hard on the surface.

"Looking at it this way, this stuff can be used to make many things."

"Build a house?"

"That won't do, too easy to break."

"Hardness is indeed a problem, lifespan won't be long, in that case it seems not very useful."

"Still somewhat useful." Tang Jing smiled: "But we still need to first see Chen Mu's ability."

Chen Mu temporarily didn't consider the actual use of foam, but instead felt puzzled about being able to easily control it.

Tang Jing again said: "Looking at it this way, it's still not complete compared to the concept of surface area."

"How so?"

"Actually, calculating, materials like cement have many internal holes, but using them is also not that difficult, seems to still match the density setting."

"Right."

"Thus, our understanding of dense objects seems somewhat off." Tang Jing pondered, then said: "Perhaps we also need to consider the adhesion property of the object."

"Huh?" Chen Mu puzzled.

Tang Jing said: "Fabric and the foam before you are still different; the latter, although similarly large in surface area, remains a whole, whereas fabric is not; a cotton thread, although composed of countless cotton fibers, is merely people rubbing them together, can be separated at any time, just like a sweater knitted from yarn, while the sweater can also be unraveled back into yarn, the two can constantly convert."

"But foam and cement are not like that; their overall form is formed by intermolecular forces, once artificially separated, cannot be recombined in reverse." Tang Jing explained.

"I understand." Chen Mu nodded: "This is also why I find controlling liquid and gaseous substances more difficult."

Tang Jing smiled: "Not bad, liquids have greater intermolecular force, while gases are already hard to consider as a whole; you think you're releasing ability into the air, but actually you're just acting on a single molecule..."

Tang Jing said up to here, then suddenly stopped, and Chen Mu also found it hard to suppress his expression of sudden realization, the two exchanged a glance in perfect tacit understanding.

Afterwards they actually said in unison: "Conductivity!"

"Unexpectedly solved two problems at once."

The happiest is naturally Chen Mu, until now he has gained a slightly deeper understanding of the connotation of his ability.

Tang Jing said: "We can make such an assumption, from the characteristic of changing object shape, your special ability's influence layer can only reach the molecular level; then, when intermolecular force is stronger, your ability's conduction becomes easier, thus solids are actually easiest to control, gases almost impossible to control."

"But on the other hand, the greater the molecular mass, the harder the control. Because under the same conditions, the greater the relative molecular mass, the greater the density, so we have always thought density affects your ability."

"These two aspects simultaneously affect your ability, so the conclusion is..."

Chen Mu took over: "The effect of ability influence is inversely proportional to relative molecular mass, and directly proportional to intermolecular force."

"Perfect!" Tang Jing clapped.

"That... what are you guys talking about?" Wei Dalei sat cross-legged on the foam plastic sofa, a bewildered face listening to the two's increasingly loud discussion.

Dong Junwei and others basically understood.

He Ying asked: "You said, will all abilities that affect object properties have this characteristic?"

This idea is not bad; it fits scientific thinking well.

Tang Jing laughed and said: "Here, currently only Lu Liangliang and Lu Shanshan's abilities belong to this category; based on my previous observation, they indeed seem to match this trait."

"Does this count as summarizing a bit of the rules of Special Ability?"
