There was plenty of time in the afternoon.

Because he was going out again tomorrow, Chen Duan focused on strengthening the practice of plastic covers.

This is the method he came up with a few days ago, and it is a cost-effective emergency evacuation method, and the effect is quite ideal.

Of course, it is better to use metal, which will have a much stronger defensive effect, but for Chen Duan, the speed of metal unfolding is far less than that of plastic, and because of the weight, it is also very inconvenient to carry.

Chen even considered making a mobile metal cover with wheels, but had no choice but to give up for the time being because the ground was not flat enough and the process requirements were too high.

However, this idea can be kept.

……

Around five o'clock in the afternoon.

Dinner was taken over by Du Jiajia.

I have to say that this girl has a bit of cooking talent, and she learns Chen Dui's movements, and she does it well.

It's a pity that the difficulty of finger cakes is several grades higher than that of rice crackers, and the food made by Du Jiajia tastes good, but the appearance is much worse.

After dinner, Chen Duan called Wei Dalei aside.

"Boss, are you sure you don't need me to go with you tomorrow?" Wei Dalei was still a little uneasy.

"The family also needs you to guard it, but I don't have much of a problem on my side." Chen Dudao.

"But ......"

"Don't be, I know in my heart, I called you here to ask you about weapons."

"Weapons?"

"Is your mace still easy to use?" Chen Du asked.

"Not bad, what's wrong?"

"I'm wondering if I'm going to give you a new bladed one, it's a little more hurtful."

"Bladed?" Wei Dalei was stunned.

"Like, axes and stuff."

Chen Du has been thinking about weapons for the past few days.

Before he left last time, he made a melee weapon for everyone to defend themselves, but first, everyone had little combat experience, let alone weapon preferences, and second, the time was relatively hurried, so he casually made a few long weapons such as spears and spears.

But now that we know the severity of the situation outside, it's time to arm the guys.

The first thing that came to his mind was, of course, Wei Dalei.

When Lao Wei first started, he actually wanted to use a long sword, because he thought it was more handsome to use a sword.

It's true, which story do you see the protagonist is using a mace to open the mountain?

Three-foot Qingfeng, fluttering clothes, that is the style.

At the very least, it has to be a knife, and the moon in the well can be reluctantly accepted.

But then I found out that the story was all a lie.

In the real world without "swordsmanship", the long sword is really a thankless weapon.

And with Wei Dalei's strength, using a sword seems a bit wasteful.

So Chen Du made him an oversized mace, completely kicking the good brother out of the ranks of the protagonists.

And Wei Dalei was a little in love with this big guy who looked a little scary.

Wei Dalei's original height was 1.97 meters, even in this era when students are generally tall, he still belongs to the existence of standing out from the crowd.

And this giant rod with steel thorns in the front section can reach the height of Wei Dalei's eyebrows when it is erected on the ground, and the thickness is even more terrifying.

Although it was made by Chen Dui, Chen Du himself couldn't pick it up at all, and when it was first made, the onlookers thought it was used as a fence.

Fortunately, Wei Dalei's strength is amazing, and he is still growing, and it is not effortless to pick up this big guy with one hand.

"I think it's pretty good."

When Wei Dalei heard that Chen Duan was going to change his weapon, he immediately clenched the body of the stick, and seemed a little reluctant.

"You haven't used anything else, so why do you think it must be better?" Chen Du smiled.

"This guy is heavy, and the lethality will be much greater when picked up." Wei Dalei explained.

"That's exactly what I'm trying to tell you." Chen Du was a little helpless: "You may have the illusion, in fact, at our current size, the weight of the weapon does not matter much. ”

"Huh?"

"The reason why you think that the destructive power of using this stick will be great is because of your own strength, and the inertial kinetic energy brought by the quality of the weapon is actually far less than you imagined." Chen Du tried to explain.

"Ah...... Yes? Old Wei became more and more confused.

"To put it simply, if you use your mace, the effect is actually similar to that of using the iron rod in my hand."

"How is that possible?" Wei Dalei looked at the appearance of the two that were more than ten times different, obviously unable to imagine this kind of thing.

"When we hit someone with something, there are generally two sources of destructive power, one is our own strength, and the other is the weight of the weapon, which may have a greater effect before it is reduced.

"A weak girl can kill a person with a hammer, but if you change to a wooden hammer of the same size, it may not be, which is with the help of the weight of the hammer itself."

"That's right." Wei Dalei nodded.

"However, when it is reduced to the scale we have now, the situation changes, the kinetic energy of the object is proportional to the mass, and if the same two weapons are reduced, if the velocity does not change, the difference in their kinetic energy will also be reduced...... You can substitute for the imagination, an iron rod and a wooden stick, smashed up will feel much worse, but a stainless steel chopsticks and a wooden chopsticks, the difference is not so big, and further, an embroidery needle and a wooden needle, there is almost no difference.

"To give a more intuitive example, if you want to smash an ant with a staple, then the weight of the staple itself has no effect, and what really kills it must be your own strength."

"Oh......"

"You understand?" Chen Du was overjoyed.

"Nope!" Wei Dalei was categorical.

Chen Du smiled: "You don't need to understand, in short, because the strength of your body now occupies the majority of the head, so for the weight of the weapon, I feel that there will be a deviation, but after experiments in the past few days, I found that this is indeed the case, and after discussing it with Tang Jing today, I came to this conclusion." ”

"So what am I going to do?" Although Wei Dalei still didn't understand, Chen Duan said this, and he didn't bother to think about it.

"Since the weight of the weapon doesn't have much effect, the mace doesn't seem to have much meaning, but the weapon with a blade will have a better effect." Chen Wei explained.

"Like an axe?"

"Yes, although in general, the advantage of the axe over the sword is still its own weight, which seems to contradict what I just told you, but from the perspective of not being easily damaged and visual deterrence, it is also a good choice for you."

"Just looks scary?"

"Yes." Chen Du smiled.

"Okay, then I'll try." Wei Dalei was as good as a stream, and immediately took out his mace and put it horizontally on the ground.

Chen Du stepped forward and reached out with both hands.
