The overworked Ye Chen fell into a deep sleep in a daze.

Thinking about it day and dreaming at night, Ye Chen began to have bizarre dreams because he had experienced too many things and his sleep quality was not very good.

Inside, Ye Chen came to an old museum, which was more like a dilapidated stone castle warehouse than a museum.

There was a gap in the dark green patina door that was half-open, and Ye Chen leaned sideways to get in.

Among the various mecha displays, of course, there are also a variety of power-assisted exoskeletons.

Ye Chen looked at it and felt very kind, he was familiar with these weapons, and some of the designs were made by Ye Chen.

Ye Chen walked over and fiddled with them one by one.

"Have you had enough?"

A hoarse voice came from the gloom at the end of the warehouse, and Ye Chen retracted his hands as if he had been electrocuted.

Looking up, following the direction of the sound, Ye Chen saw a white-bearded old man with a rickety body, and a twisted branch in his hand.

"Who are you?"

Ye Chen subconsciously took a few steps back.

In an unfamiliar environment, Ye Chen was extremely vigilant.

"I'm an artist...... And you, you're a little trash. ”

The old man said contemptuously, his tone was already arrogant and boundless.

Although Ye Chen is not a top expert in the field of weapon design, the various weapons and equipment in his hands are very recognized by the people around him, how can he become worthless as soon as he comes to the mouth of this old man?

Is he an unreliable old fool?

Ye Chen stared at the old man with his eyes, wanting to see if there was something wrong with his spirit.

"The weapons you designed are all artificially operated, right? Something like a power-assisted exoskeleton needs to be worn by a person to be effective?"

"Isn't that nonsense? Listen to the name, the exoskeleton, it must be used on people......"

"Hey, you short-sighted little trash, your level is limited to this. Now you may have a smooth sail, and when you really hit the hard stubble, you will be sure to be separated from life and death. ”

"Hey, don't brag about it, what I've designed hasn't failed yet. ”

"Okay, if nothing else, just look at your power-assisted exoskeleton. The function of this equipment is to increase attack power, and it is melee combat, right?"

Ye Chen nodded, what the old man said was not wrong, because the power exoskeleton was attached to the combatant's body, so he was not a long-range attack weapon, and he could only greatly improve the user's movement attributes such as strength and speed.

"You're right, and then?"

"Bones, not armor, right? After design and production, the gaps in the skeleton are not defenseless, and whether they become defects. ”

"I admit it, but this structure is more flexible, and the amount of material used is reduced, which reduces the burden on the body of the wearer. ”

"Can your power-assisted exoskeleton make the user faster than a bullet?"

Ye Chen shook his head.

"Can it surpass the four shots of shrapnel at the time of the explosion?"

Ye Chen shook his head again.

The old man sighed helplessly and slowly walked towards Ye Chen.

"Melee combat, is a fight between life and death, if the other side loses the upper hand, when it is about to be killed, the means of using the same end to the end detonate the *** on the body, you say, what is the role of your power exoskeleton? Can it be the wearer's teleportation and escape from the explosion zone?"

"This ......"

Ye Chen was speechless for a while.

"Even if the help exoskeleton has some protective measures that can simply defend against the gaps between the bones, I can tell you clearly that the protective shield condensed by energy alone is not as strong as the physical material, no matter how much energy your protective shield energy is condensed, you know no, if you encounter hard stubble**, you will become meat foam in minutes. ”

Ye Chen's face turned red, and he couldn't say a word.

"Don't be unconvinced, I said you are a piece of garbage, that must be well-founded, let's not talk about your power-assisted exoskeleton, how about a battle mech?"

The old man came to Ye Chen's side, and kept tapping the display mecha on both sides of the warehouse with his cane.

"Say, which one of you look at is powerful, I'll analyze it with you now. ”

"This!"

Ye Chen pointed with his hand and picked a new model.

"Hey, you've had too many days of smooth sailing, I don't know how thick the sky is, I'm going to tell you a few simple, fast, and quick ways to destroy this mecha model in the shortest possible time. Rest assured, this is not a lever lift, the methods I am talking about are low-cost and easy to implement. ”

"I'm listening!"

Ye Chen stood in front of the mecha and looked at this battle fortress with confidence.

"Have you ever fought in the winter?"

"So...... Nope!"

Ye Chen recalled for a moment and shook his head.

"If you have a knowledge of physics in junior high school, you should know that any metal has a cold brittleness phenomenon. I don't need to explain what cold brittleness is, right?"

Ye Chen is not illiterate, so he naturally knows this physical phenomenon.

The cold brittleness in the old man's mouth, that is, low-temperature brittleness, refers to the phenomenon that the impact toughness of most metals or alloys decreases sharply under lower conditions. In layman's terms, this kind of metal is particularly brittle at low temperatures, not as strong as usual, and sometimes as brittle as ice, and it will break when touched.

"The mecha you designed is for actual combat, not an exhibit in a glass case. Since you want to do it, you need to mass produce it, and the condition for mass production is that you can't make it out of very expensive, very rare metals, right?"

The old man's words hit the nail on the head, and the reality is true.

"I ...... I can avoid fighting in the winter, I ......"

"What are you, pale and feeble quibbles will make your teammates die quickly. The old man pointed out a few spots on the mecha's body with a branch.

"It's not that the conditions of low temperatures only exist in winter, let me tell you, if I want to deal with a mecha like you, I can prepare some liquid carbon dioxide in advance. Find a gap and pour it on the mecha to make sure you have a cool heart. When the time comes, there is no need to attack you again, the force generated by your own movement is enough to make the cryogenic components fall apart. ”

Liquid carbon dioxide is also known as "dry ice". This thing can be found everywhere and is often used to create stage effects and artificial rain.

A bucket of dry ice scraps a mech, this is definitely a good deal.

"Don't say that your mecha main steel plate is very strong, I poured dry ice on the joints of your limbs, here is the least defense, the most line connection, then you will wait dumbfounded." ”

Ye Chen was already dumbfounded when he heard this.

Maybe he's really a weapon design junk......
