Humans Shrunk 100 Times

I'm not sure why, but even though the initial intention was to test Lu Shanshan's abilities, the conversation always seemed to unconsciously shift towards Xue Xu.

Chen Mu got back to the point: "The significance of sealing the door's gap, I believe everyone understands. The reason I called you siblings here is that I think your abilities could be helpful in this regard."

"What can we do to help?"

"We need to test it out first."

Chen Mu pointed to an iron rod lying on the ground, which was being used as a makeshift fence, and asked Lu Shanshan, "Can you use it as an experimental subject?"

Lu Shanshan glanced at her brother and nodded, saying, "Yes, I can."

She then walked over to the rod.

For humans now, a 3-millimeter diameter iron rod, strictly speaking, should be called an iron pillar. Its length of two centimeters is even longer than a person's height. Relying on his own strength, Chen Mu couldn't lift it no matter what. However, his current ability allowed him to manipulate iron objects with the same volume as himself without any difficulty.

Lu Shanshan placed her hands on the surface of the iron rod and then closed her eyes.

After about half a minute, she opened her eyes and let out a breath.

"Is it done?" Chen Mu asked curiously.

"Yes."

"Your ability requires physical contact with objects, right?"

"Yes."

"Have you ever tried using your feet?" Chen Mu suddenly asked.

"No, I haven't," Lu Shanshan was puzzled, "Should I try?"

"Not necessary for now, maybe later."

After saying that, Chen Mu went to the side of the iron rod and squatted down, using both hands to lift one end of the heavy iron rod.

The heavy iron rod was slightly lifted off the ground for a moment but quickly slammed back down.

"No effect?" Tang Jing asked.

"Completely ineffective," Chen Mu, who had been hanging around with this pile of iron rods for days, knew their weight well. He turned to Lu Shanshan and asked, "Could you feel any impact on it?"

Lu Shanshan shook her head, saying, "I can only feel the energy from myself entering the object, but I have no control over what changes, if any, occur. I can't even sense it."

"Perhaps it's because they're too big?" Tang Jing suggested.

"Yeah," Chen Mu quickly realized that testing Lu Shanshan with his own power limit was indeed not appropriate.

He then separated a fist-sized iron sphere from his weapon and handed it to Lu Shanshan, saying, "Try this one."

Lu Shanshan took the iron sphere and, just like before, closed her eyes and focused. However, this time, it took much less time, about 10 seconds, to complete the task.

"It's indeed lighter," she said.

Chen Mu took back the iron sphere and clearly felt that its weight had reduced significantly, but its appearance remained unchanged.

Tang Jing also took the iron sphere and shook it, nodding slightly, "Indeed."

Chen Mu then made another iron sphere with almost identical appearance, and by comparison, it weighed about half as much.

"Do you think you've done your best?" he asked.

"Yeah, I can only achieve this level at most each time, and using the ability a second time on the same object won't have any effect," Lu Shanshan replied with regret in her voice.

Among the four of them, Lu Shanshan was relatively forward-thinking and had the most detailed understanding of her abilities.

If this ability could work without limits on the same object, theoretically, she could reduce its weight to zero.

With an object having no weight, there would be many possibilities.

But clearly, such a good thing did not exist.

Although Chen Mu felt a bit regretful, it was within his expectations. Regardless of Lu Shanshan's strength, superpowers themselves come with certain limitations. It's impossible to allow someone to become excessively powerful.

"Tang Jing, can you calculate the mass of this iron sphere?"

"Let me see."

Tang Jing walked over and made a few gestures with her fingers, then said, "The diameter is about 0.8 millimeters, and based on that, the volume is approximately 0.00027 cubic centimeters. Assuming a density of 7.8, the weight is 0.0021 grams."

The volume and density formulas for a sphere were basic knowledge, something even elementary school students could figure out with a piece of paper. However, being able to calculate it mentally in such a casual manner was a feat that few could achieve.

Chen Mu was used to Tang Jing being a human calculator, but Lu Shanshan and her brother were amazed.

"So, Lu Shanshan's ability can only reduce the weight by 0.001 gram at a time?"

"Isn't that too little?"

"It's not that little, considering we are not that heavy ourselves, and abilities will always grow."

"Moreover, it's too early to draw conclusions based on just one set of experimental data," Tang Jing said. "Let's try with a different material."

Chen Mu brought another piece of plastic, made into the same shape as the previous iron sphere, and had Lu Shanshan repeat the process.

This time, after Tang Jing's calculation, the weight reduction was even less than before, almost ten times less.

"Let's try with a larger one."

Chen Mu already had a suspicion in his mind, but he couldn't conclude anything without testing it.

This time, they used a plastic block about the size of a human head.

The result came out, and just when everyone was still puzzled, Chen Mu and Tang Jing simultaneously said, "I understand."

"Is it reduced proportionally?" Chen Mu looked at Tang Jing.

"It seems likely."

"The degree of weight reduction is related to the object's initial weight."

Tang Jing nodded, saying, "Lu Shanshan's ability probably reduces the object's weight by half, up to a certain weight limit. However, it's still unclear whether it can exceed the 50% mark."

"Furthermore, there's the issue of determining the overall object. For example, if two spheres are placed together, should we consider them together or separately?"

"... "

The two of them discussed freely, oblivious to anyone around.

He Ying probably grasped some understanding.

But Lu Shanshan and Lu Liangliang were even more puzzled, and they were amazed by Tang Jing's rapid-fire calculations.

"So, can you tell me what's going on with my ability?"

Lu Shanshan felt a bit embarrassed, as it seemed like someone else understood her ability better than she did.

"Don't be in a hurry; we still need to do some verification calculations."

Chen Mu walked up to the large plastic cube where the last experiment was conducted, placed his hand on it, and said, "But if our guess is correct, it'll be very interesting."

As he finished speaking, the plastic cube dissolved at lightning speed and then transformed into various dazzling shapes around everyone, finally reverting to a similar cube.

However, this cube was several times larger.

It was like a room, engulfing all five of them.

Before Chen Mu even acted, Tang Jing already knew what he was going to do and smiled at this point.

Although He Ying was surprised, she quickly understood what was happening.

Only Lu Shanshan and Lu Liangliang were staring at the suddenly gigantic object appearing above their heads, utterly stunned.
