Chapter 102 Metallic Hydrogen

"To be precise, water is more than 9,000 times denser than hydrogen."

"Bad Copper" explained: "But 1 cubic centimeter of metallic hydrogen weighs 1 gram, which is several orders of magnitude different from the density of hydrogen. To make metallic hydrogen, you need to pressurize the hydrogen from a gas into a metallic state. It's just

This is not easy because it requires at least a pressure close to 500Gpa."

Chi Heng frowned: "Is it difficult?"

Since "broken copper and scrap iron" are said so, there must be some difficulty.

Sure enough, it went on to say: "The pressure at the center of the Earth's core is 360Gpa, and the pressure at which TNT explodes is 10Gpa. In its natural state, metallic hydrogen only exists inside the planets of Jupiter and Saturn in the solar system."

Chi Heng smiled bitterly when he heard this: "Are you kidding? You can't go to Jupiter to mine."

He suddenly had an idea: "Since the explosion pressure of TNT explosive is 10Gpa, wouldn't it be able to reach the minimum requirement of 500Gpa if it explodes 50 times at the same time?"

"Broken metal": "???"

Chi Heng smiled and waved: "It's just a joke, don't take it seriously."

"It is a liquid food that can provide specific nutrients for human survival such as carbohydrates, proteins, antioxidants, water, vitamins and minerals for growth and reproduction."

Chi Heng looked at a set of machines, which looked like a refrigerator, with a nozzle. There was indeed a lot of ground debris in the box below.

Chi Heng suddenly realized and pointed to the K4 level laboratory in the distance: "The unrestricted 3D printer must be in there..."

Chi Heng was confused: "Then how did my old uncle break through the restrictions? Junk, there must be a way to break through the restrictions, right?"

"Broken Copper" stepped forward and pinched some debris with its mechanical claws: "Sir, the top layer of debris is the product of dried fluidized food. Judging from the degree of dryness, it will not exceed 12

hours.”

Chi Heng thought for a moment and could only think like this, "Let's look for the diamond anvil you mentioned."

One person and one machine started the search again, focusing on continuing to investigate the laboratory.

"yes."

Chi Heng sighed. Compared to firearms, he didn't have to worry too much about it yet. The "Red Dragon" was enough for the time being. The key was the bullets. Firearms without bullets were scrap metal, and he only had 15 bullets left.

Bullet... I had a nightmare, and 4 bullets disappeared inexplicably, which made Chi Heng both frightened and annoyed.

"Sir, what do you mean..."

"Can't you hack in? I mean change the underlying protocol?"

"Sir, this is a limitation of the underlying protocol, Junk can't do anything about it."

"In addition, Junk, I have another idea," Chi Heng's eyes flashed, "The civilian version of the 3D printer is indeed limited to printing military weapons, but what if it is printed in segments?"

"Yes, the red dragon itself is not formed in one piece, right?"

"Broken Copper" said: "There should be much more than now, forming a build-up."

"I see."

Chi Heng's face turned ugly, "In other words, someone here is using a fluidized food maker?"

"Has it been activated?"

This kind of K1-level laboratory does not require a permit and can be passed directly. It is impossible for Chi Heng to let go of such an abnormal clue. After stepping in, he found that the traces on the ground mainly came from a kind of debris. He squatted down and wore a

He didn't have to worry about safety in the protective suit, and there was no threat in the low-level laboratory. He picked up the crumbs on the ground and pinched them. "It feels like some kind of crushed biscuits."

"In other words, even with a 3D printer, I can't print weapons, let alone bullets?"

To Chi Heng's surprise, all the laboratories he visited along the way were neat and tidy, but the K1-13 laboratory in front of him was in a mess, like a scene left behind after several huskies caused trouble inside.

“What is fluidized food?”

Chi Heng turned around.

Regarding Chi Heng's cunning idea, "Bad Copper" thought about it carefully and nodded: "Sir, this is indeed a feasible method, but we must also try it. If the printer limits the parts of the firearm, then the conventional

The parts are definitely not printable, and in addition, there is still no way to solve the most important bullet problem."

"Can this still happen?"

If you can get into the lab, go in; if you can't get into the lab, just give up temporarily.

Chi Heng already understood how his uncle circumvented this restriction, "Isn't it enough to print in sections and then assemble them?"

Chi Heng's arm holding the Glock17 pistol trembled, and he asked seriously: "Is it possible that the equipment is damaged? Did it spray out on its own?"

"The possibility is very high."

"Impossible." "Bad Copper" pressed the touch screen of the device. After a few clicks, a large amount of milky white mixed liquid spurted out, more than 400 ml in one go.

"Hey, this laboratory..."

"If that doesn't work, let's buy weapons from outside."

"The underlying protocol belongs to hardware security. Once you try to modify the underlying protocol, the physical fuse mechanism will be triggered, causing the fuse inside the 3D printer to blow. The entire 3D printer will be in a state of maintenance emergency and lose its working ability." "Broken copper and iron" rejected Chi.

A balanced approach.

Initially, Chi Heng was just listening. After these words, his expression suddenly changed: "Wait a minute, what do you mean when you say it won't exceed 12 hours?"

Naturally, the "broken copper and scrap iron" did not object.

"Bad Copper" replied: "This fluidized food maker was activated 12 hours ago."

"If it's caused by equipment damage, it can't be just this little bit of debris."

Chi Heng didn't believe it: "Is there no way around it?"

Then it is natural that military 3D printers exist.

"Bad Copper" was silent for a moment, shook his head, and nodded again: "This is a civilian version of 3D printer. Military 3D printers do not have this limitation."

Chi Heng stood up again, and the "broken copper" behind him walked in. He lowered his head and glanced at it a few times, and said, "Sir, this is formed after the fluidized food dries up... That is the fluidized food maker."

"Bad Copper" also agrees. After all, the large number of infantry fighting vehicles found in the "garage" proves that this base is not just for research purposes, but also has major military considerations.

"What?"

Bullets are too restrictive. It is impossible to rely on segmented printing to hide the printer, especially the most critical metal hydrogen inside the bullet. Without this, it would not be so powerful.

"The most effective means of producing metallic hydrogen in the laboratory is the diamond anvil, which can generate pressure exceeding 500Gpa to produce metallic hydrogen, but the loss is large, and Junk has not discovered this equipment."

Chi Heng, who was shocked, never thought that there would be anyone in the research base.

First, it was his uncle's notes that gave him this impression, and the notes of the deceased he finally obtained also verified this guess.

Especially after he came all the way in, he found no living creatures, not even the humanoid monster found on the edge of the bottomless pit.

Chi Heng asked without giving up: "Could it be the humanoid monster we... saw before?"
