Looking at Wei Fan and Zhang Yaqing, both bewildered.

For some reason, Zeng Gu Cheng suddenly thought of his students in class.

So he smiled and explained:

"We've just analyzed that these microcrystals formed by ferrous helium release blocking energy in the form of surface energy—because they need to form dihelium, ferrous ions must detach from their compound state.

And in this area...

Perhaps the magnitude of zero-point energy is 'infinite,' enough for ferrous helium to be generated countless times.

But the number of helium and ferrous ions is limited.

All we need to do is use some methods to force a large number of microcrystals to decompose, and then use anions like cyanide ions to react with the decomposed ferrous ions to generate potassium ferricyanide solid to collect.

The stability of potassium ferricyanide is very high, and it does not decompose unless through a thermogravimetric reaction."

Just as Zeng Gu Cheng said.

Even though this chamber is located near an iron ore mine, the number of iron ions in the chamber is limited.

Not to mention divalent ferrous ions.

The gas wall can persist because the ions resulting from the decomposition of ferrous helium continuously react, keeping the number of ferrous helium microcrystals stable—not in specific numbers, but in magnitude, because their base number is so large.

That is to say, as long as we keep using an energy to impact the gas wall, keeping it in a state of microcrystal decomposition, and use some methods to transform ferrous ions into other substances.

Then, ferrous helium will be unable to form due to a significant reduction in ferrous ions.

After all, your vacuum zero-point energy can be drawn from a vacuum state, but ferrous ions rely on some long-term oxidation reaction of elemental iron in the ore, and their quantity cannot increase in the short term.

Then Zhang Yaqing, the curious one, asked further:

"Academician Zeng, what are the means you mentioned to force the crystals to decompose?"

Zeng Gu Cheng thought for a moment, looked at Lu Chaoyang, and said:

"I think we can try using an ion beam. What do you think, Professor Lu?"

Lu Chaoyang pondered for a few seconds, then nodded:

"I think it's feasible."

As previously mentioned.

The characteristic of ferrous helium microcrystals in the barrier zone is a large number and small size.

Like in the few seconds Lu Chaoyang was blocked earlier.

There have already been tens of thousands or even millions of conversion phenomena in the surrounding area of the barrier zone.

But they are so tiny that they are barely discernible to the naked eye.

If measured with machines, there might be a micron or nanometer level dent.

After all, the function of the barrier zone is to block and not necessarily to stick to the 2.33333m value.

The ice coffin is not an AI; it can't achieve such precise values.

Countless microcrystals continuously provide solid surface energy. The hundreds of megas of quantity stacked together are enough to resist any known individual attack in the Damo Realm.

There's nothing to be done; vacuum zero-point energy is just that domineering.

Theoretically, this thing is the best energy for interstellar travel.

The zero-point energy provided by one square meter of vacuum area is enough to fly to Betelgeuse, and providing a defense energy for an area of several square meters is extremely easy.

It's not an exaggeration to say.

Even if you let a Divinity Transformation Realm cultivator strike, they absolutely won't break it, because it repairs too quickly.

Unless you can achieve uninterrupted bombardment for 24 hours, without stopping for even a second, or achieve particle-level pinpoint destruction—and both are almost impossible in the Damo Realm.

It's like you keep drinking freshly squeezed apple juice, while a machine on the side squeezes apples into a container with hundreds of standard atmospheres pressure every few seconds.

Under this pressure, each apple is almost juiced the instant it is squeezed inside and sent out.

Unless your juice drinking speed is fast enough or you've discovered the machine's shutdown password.

Otherwise, you'd just waste time on drinking juice without being able to do anything else.

If the ice coffin had life, this would be its "confidence."

But no matter how much the ice coffin thinks, this defense, which is nearly invincible in the Damo Realm, is really nothing to those rabbits.

This has nothing to do with combat power, but everything to do with the degree of understanding of micro and macro realms.

You're invincible from the cultivation perspective, so we switch our thinking, tackling you with physics and chemistry rules.

What's that saying?

Solid knowledge in science will prevent fear in any corner of the world!

In summary.

The suspected vacuum zero-point energy detection of the ice coffin is shocking, and it belongs to the situation where even if you discover it, you might not be able to utilize it.

But from another angle,

As long as it's confirmed that there's really a vacuum state behind the ice coffin, it further proves that the Damo Realm is a world abiding by physical rules, where energy does not spontaneously generate.

From a research perspective, it's a morale booster, telling everyone they are on the right path.

Returning to the underground chamber.

After a simple discussion of the strategy.

Lu Chaoyang and the others returned to the surface and reported this information to the command center.

The command center promptly gathered many experts, including Academician Pan Jianwei, to discuss Zeng Gu Cheng's plan more comprehensively, and in the end...

It was unanimously approved!

Just like that, nearly an hour passed.

A medium-sized ion beam emitter machine was delivered to the site.

It's worth emphasizing here, ion beams are not the same as particle beams, they're not the same concept.

Those who didn't fail chemistry should know this.

Ions are atoms or groups of atoms that have lost or gained one or more electrons, forming charged particles, so ion beams can be said to be a subset of particle beams.

Ion Beam ＜ Particle Beam.

The reason the rabbits chose ion beams this time is simple:

Ion beams have a strong dispersion effect, meaning the beam will self-diffuse after leaving the emitter's magnetic field constraints.

This dispersion effect makes ion beams less efficient than particle beams in terms of energy weapons, which affects their penetrating ability.

So energy weapons like those in Star Wars are generally proton beams or even neutron beams, not particle beams.

But this time, the rabbits' goal was to slowly whittle away the blood limit of the barrier, rather than trying to penetrate it completely in one go, so the dispersion effect of the ion beam is actually a good thing.

The rabbits say, we're old hands at whittling down a boss's health bar.

Apart from that.

The penetration capability of an ion beam along different crystal orientations also varies, making ion channeling effects the best choice for polycrystalline materials.

Iron helium, conveniently, is a hexagonal microcrystalline.

Just as Wu Qian's sparrow is still a sparrow, microcrystals are still a type of crystal.

Therefore, ion beams are the best choice.

Simultaneously sent to the site with this ion beam emitter machine were several sets of more rigorous protective suits.

This was because Lu Chaoyang and others intended to use ion beams not just any ion beams, but specifically cyanide ion beams.

Cyanide ions are extremely toxic substances, chemically on par with the nature of the three major toxic criticisms in online literature.

Much like how authors who survive under the three major toxic criticisms are rare, so are people who can survive cyanide ions.

But why did the rabbits choose cyanide ions instead of heavy ions like mercury ions as the beam source?

The reason is simple—the toxicity explains it.

Cyanide ions are toxic due to their extremely strong coordination ability:

They interfere with metals ions that aid normal functions in the body—or in animal cells, like iron ions, for example... or ferrous ions.

Once again, knowledge for those who didn't fail chemistry.

Hemoglobin contains ferrous ions to transport oxygen, and mitochondria need iron-sulfur proteins to facilitate the oxidation and reduction of ferrous and ferric ions, ultimately producing ATP through oxidative phosphorylation.

Once ferrous ions are bound by cyanide, they become unnaturally stable at room temperature and hard to dissociate, leading to a complete breakdown of the respiratory chain.

The result is hypoxia within cells, tissue necrosis, and eventual animal death.

This is why cyanide ions were chosen—they are too stable.

A beam containing about 14 billion cyanide ions can react directly with disassociated ferrous ions at the impact center.

A typical case of killing and scattering ashes, without even needing a crematorium.

Three hours later, all equipment was ready.

Zhang Mu and five other experts in protective suits stood by the machine.

The energy level of the cyanide ion beam isn't as strong as a particle accelerator's; both radiation and deflection energy are completely blocked by protective suits, so having people present is not an issue.

A short while later, his assistant Lu Jie raised his hand from the console:

"Teacher, the ion beam is ready as well, 5.11 meters from the barrier, capable of uninterrupted emission for more than seventy-five hours."

Zhang Mu nodded:

"Then let's begin."

"Understood!"

Lu Jie, with a serious expression, pressed the switch on the beam emitter.

"Buzz Buzz Buzz—"

The outer shell of the emitter vibrated with a rhythmic thrum, then a stream of ions shot straight from the emitter's mouth, colliding head-on with the barrier!

The energy of the emitter is 15MeV, in a 20cm X 20cm irradiation area it could roast a piece of meat in about 100 minutes—don't ask why they know, if you've never used a linear accelerator to roast meat, can you really call yourself a physicist?

But when the area is reduced to 1 square centimeter, the instantaneous contact energy becomes very large.

Except for Boruto, basically nothing can withstand such burning.

So everyone began patiently waiting.

Since it was terribly boring, they started playing Landlord Poker — five experts plus two assistants and Zhang Yaqing and Wei Fan made nine players, just enough for three decks.

About an hour later, pale yellow crystalline particles began to fall.

After five hours, a significant portion of the barrier had visibly dissipated, and the rangefinder showed a value of 1.975 meters.

...

Forty hours later.

The ion beam advanced to within five centimeters of the ice coffin.

Forty-three hours later.

The barrier completely disappeared.

At the same time, perhaps due to the age.

The skeleton by the side of the ice coffin suddenly made a cracking sound—

The jaw fell to the ground.
