Humans Shrunk 100 Times

Afternoon was relatively ample.

Because he would be going out again tomorrow, Chen Mu focused on strengthening the practice of the plastic cover.

This was an idea he came up with a few days ago, which could be considered a cost-effective and effective emergency measure, with reasonably satisfactory results.

Of course, it would be best to use metal, as it would provide much stronger defense. However, for Chen Mu, metal couldn't unfold as quickly as plastic, and due to its weight, it was not convenient to carry around.

Chen Mu even considered making a mobile metal cover with wheels, but due to the uneven ground and high craftsmanship requirements, he had to give up temporarily.

However, this idea could be kept for future consideration.

...

Around five in the afternoon.

Dinner was taken care of by Du Jiajia.

It had to be said that this girl had some cooking talent. Following Chen Mu's movements, she managed to cook with some resemblance.

Unfortunately, the difficulty of hand-grabbing pancakes was several levels higher than flatbreads, and the food made by Du Jiajia tasted fine when eaten, but its appearance was far from appealing.

After dinner, Chen Mu called Wei Dalei aside.

"Boss, are you sure you don't need me to go with you tomorrow?" Wei Dalei still had some concerns.

"The family needs you to guard, but I shouldn't have any problems on my side," Chen Mu said.

"But..."

"No need for 'buts.' I know what I'm doing. I called you over to ask about weapons."

"Weapons?"

"The wolf-tooth club you're using now, does it still feel comfortable?" Chen Mu asked.

"It's not bad. What's the matter?"

"I was thinking whether I should get you one with a blade. That way, it would have better offensive capabilities."

"A bladed one?" Wei Dalei was taken aback.

"For example, an axe or something similar."

Chen Mu had been thinking about the issue of weapons these past few days.

Before he left last time, he made a melee weapon for everyone as self-defense. However, firstly, none of them had much combat experience, let alone preferences for weapons. Secondly, time was limited, so he hastily made some long weapons like spears and long spears.

But now, understanding the severity of the situation outside, it was time to arm everyone.

The first person he thought of, of course, was Wei Dalei.

Initially, Old Wei wanted to use a long sword because he thought it looked cool.

Indeed, that was the case. Which protagonist in stories wielded a wolf-tooth club like an axe?

A three-foot green blade, flowing robes—only then did it have style.

At the very least, it should be a knife. Well, the idea of using a moonblade would be acceptable.

But later, he discovered that stories were deceiving.

In a reality without "swordsmanship," a long sword was really an impractical weapon.

Moreover, given Wei Dalei's strength, using a sword seemed a bit wasteful.

So, Chen Mu made him an oversized wolf-tooth club, completely removing the good brother from the protagonist's ranks.

After receiving this somewhat intimidating big fellow, Wei Dalei surprisingly couldn't put it down.

Wei Dalei's original height was 1.97 meters, and even in this era of generally tall students, he was an outstanding figure.

And this giant rod, with the front covered in steel spikes, stood at the height of Wei Dalei's eyebrows when placed on the ground, and its thickness was intimidating.

Although it was crafted by Chen Mu, he himself couldn't even lift it. When it was first made, the onlookers even thought it was meant to be used as a fence.

Fortunately, Wei Dalei had astonishing strength, and he was continuously growing. Swinging this big weapon with one hand was effortless for him.

"I think it's pretty good," Wei Dalei said when he heard that Chen Mu wanted to replace his weapon, immediately gripping the shaft as if he was a bit reluctant to part with it.

"You haven't used anything else, so how can you be sure it's the best?" Chen Mu smiled.

"This thing has some weight to it, so it will deal more damage when swung," Wei Dalei explained.

"That's exactly what I wanted to talk to you about," Chen Mu said with some helplessness. "You may have a misconception. In reality, the weight of the weapon doesn't matter much given our current size."

"Huh?"

"The reason you think using this club gives you more destructive power is that your own strength is great. The inertial energy brought by the quality of the weapon is far less than you imagine." Chen Mu attempted to explain.

"Huh...?" Old Wei became even more puzzled.

"To put it simply, when you and I use our respective weapons to strike someone, the destructive power generally comes from two sources: our own strength and the weight of the weapon. Before we were shrunk, the latter might have even had a greater impact."

"But how is that possible?" Wei Dalei looked at the two vastly different appearances of the weapons and couldn't imagine such a thing.

"When we use the same thing to hit someone, the destructive force comes from two main factors: our own strength and the weight of the weapon. Before we were shrunk, the latter might have an even greater effect," Chen Mu continued to explain.

"A weak girl, for example, can kill someone with an iron hammer, but if she were to switch to a wooden hammer of the same size, it might not be as effective. This difference is due to the leverage of the iron hammer's weight."

"Yeah," Wei Dalei nodded in understanding.

"But, after shrinking to our current size, the situation changes. The object's kinetic energy is directly proportional to its mass. If we shrink two weapons while keeping their speed the same, the difference in their kinetic energy will also decrease. You can imagine it like this: if you shrink an iron rod and a wooden rod, the feeling when you strike with them will be quite different. However, if you go further down, the difference between a stainless steel chopstick and a wooden chopstick won't be that significant. And if you go even smaller, like a sewing needle and a wooden needle, there will be almost no difference.

"Here's a more straightforward example: if you want to kill an ant with a paperclip, the weight of the paperclip itself won't matter much. What will actually kill it is your own strength."

"Oh..."

"Do you understand?" Chen Mu was pleased.

"No!" Wei Dalei said firmly.

Chen Mu chuckled and said, "It's not necessary to fully understand. In short, because your physical strength now plays a significant role, you may have a biased perception of the weight of the weapon. But after conducting experiments these past few days and discussing it with Tang Jing, I came to this conclusion."

"What should I do then?" Although Wei Dalei still didn't fully grasp it, he didn't bother thinking too much since Chen Mu said so.

"Now that the weight of the weapon doesn't matter much, the wolf-tooth club becomes less meaningful. Instead, a bladed weapon will have a better effect," Chen Mu explained.

"Like a mountain axe?"

"Yes, although in general, the advantage of an axe compared to a sword still lies in its weight, which seems contradictory to what I just told you. However, from the perspective of being less prone to damage and having visual intimidation, it's still a good choice for you."

"So, it's about looking intimidating?"

"Yes," Chen Mu smiled.

"Alright, then I'll give it a try." Wei Dalei quickly took out his wolf-tooth club and placed it horizontally on the ground.

Chen Mu stepped forward and reached out with both hands.
