After getting inspired by Old Su.

Xu Yun didn't dare to delay.

He immediately decided to return to the site to share this idea with Yu Yuanyong and others.

"What? Using liquid as an intermediary?"

Upon hearing this idea.

Yu Yuanyong looked surprised at Old Su's 'I'm just a bystander' face, and immediately fell into deep thought:

"The iron ion beam density we use is a low-energy ion beam of 110keV, and there should be three spectral bands with phase shifts in one period."

"If we set up a constant period liquid device, feedback the band when the phase shift appears to bring it back to balance..."

"Hiss, could it really be possible?"

Considering that some students might not quite understand the nature of the intermediary in this reaction, here's a very simple example to illustrate—it's truly the simplest kind.

Suppose there is a very long conveyor belt, and the height at the feed port is 4 centimeters, and 95% of the items on the conveyor belt are 3 centimeters.

Three centimeters against four centimeters.

These items can naturally pass smoothly through the feed port.

But besides these three-centimeter items, every certain period on the conveyor belt—say every 30 seconds, a giant object of 5 centimeters appears.

However, due to various restrictions, the feed port cannot be permanently raised, thus there will be instances where materials get stuck.

And at this moment, someone proposed a solution:

Although we can't permanently raise the feed port, we can set a program.

So that each time the five-centimeter giant object period occurs, the feed port can temporarily be raised to six centimeters for a few seconds, right?

Perhaps such an approach requires a certain cost, but it is obviously much lower than permanently raising the feed port.

At least within an acceptable range.

Although the practical part nowadays requires Xu Yun and others to consider much more complex issues than the example above.

In nature, however, the two are actually interoperable, both balancing certain abnormal energies through connecting periods.

Upon thinking of this.

Yu Yuanyong couldn't sit still for a moment, turning around to say to Xu Yun:

"Dr. Xu, what do you think we should use to balance the liquid?"

Xu Yun used his right hand to form a figure eight in front of his nose, while his left hand picked the report up from the table again, carefully glancing over it.

Chemical intermediaries.

As the name suggests, these refer to some common intermediary substances in the chemical industry, subdivided into 11 main categories.

Among these 11 categories, besides additives, chemical medicines, and daily chemicals.

They also include reagents, coatings, and dyes, which are liquids.

However, what Xu Yun and Yu Yuanyong discussed obviously wasn't these conventional liquids, but rather certain concentrated special liquid materials.

This material must first have the property of not participating in subsequent reactions and possess suitable attributes, while also not reacting with the iron ion beam.

Thus.

A considerable portion of salts is excluded.

Next, the molecular interaction of this material must be considered, which is the coordination of molecular spatial configuration in the hybrid orbit.

So Xu Yun thought for a moment.

He took paper and pen, wrote down a term, and handed it to Yu Yuanyong:

"Director Yu, what do you think of this?"

Yu Yuanyong looked at the result:

"Ferricyanide potassium?"

Xu Yun nodded, explaining:

"The ligand of ferricyanide potassium is CN-, with a coordination number of 6."

"If I remember correctly, its mass-to-charge ratio at the 110keV energy level should be around 11.5, specifically something like 11.54 or so, which is very close to our requirements."

"Also, because its central atom is a trivalent iron ion, it will only react with ferrous particles, naturally having a compound barrier with the iron ion beam."

"Although ferricyanide potassium is toxic, its industrial application range is actually very broad, and it should meet the requirements when used as an intermediary in sealed equipment."

Just as Xu Yun said.

Ferricyanide potassium is a red crystal, its aqueous solution has a yellow-green fluorescence, and forms a deep blue precipitate when encountering ferrous salts.

It is also easily reduced under sunlight and can be completely Feng Jie when burned, producing highly toxic cyanide and cyan.

Students who were poisoned by cyanide in a past life should all know.

Cyanide is an alkaline substance, directly stimulating mucous membranes and causing irritation, leading to faster and deeper breathing, fatigue, headache.

Then you start experiencing difficulty breathing, increased blood pressure.

Because the tissues cannot utilize oxygen, the venous blood oxygen saturation increases, turning the skin and mucous membranes cherry-red.

Finally, you experience convulsions, whole-body muscle relaxation.

Thus, leading to cardiac arrest, multiple organ failure, and rapid death.

Therefore, in civilian applications, ferricyanide potassium has always been a strictly controlled substance.

However, in industrial fields, this thing is still quite common.

It is widely used in photographic paper, printing, pharmaceuticals, fertilizers, steel, and other industrial applications.

It's considered a highly prevalent and legal substance.

Upon thinking of this.

The gleam in Yu Yuanyong's eyes grew a bit brighter, pondering aloud:

"Ferricyanide potassium... ferricyanide potassium... it really might be possible?"

Then he thought for a moment, looked at his assistant by his side, and asked:

"Xiaoqian, can you check the database to see where the CN bond stretching vibration appears under ten atmospheres for ferricyanide potassium?"

Xiaoqian, mentioned by Yu Yuanyong, is a rare woman in the field of chemicals, sporting short hair and looking quite competent.

She tapped quickly on the keyboard, and soon after looked up and replied:

"Found it, the range is 2356-3091cm^-1."

"What about the radicals?"

Xiaoqian tapped on the keyboard a few more times:

"Rank 45."

"Rank 45..."

Yu Yuanyong repeated the number thoughtfully, and glanced at the previous test results.

Although detailed peak comparison still requires experimental calculation, judging from a purely data perspective...

Iron potassium cyanide does seem like a pretty good choice?

In fact, the intermediate Yu Yuanyong initially thought of was cobalt iron carbonate composite salt, a substance commonly used in lithium batteries.

But just as its name suggests, cobalt iron carbonate composite salt is a compound with very complex components.

Although it can achieve good intermediate effects in a molten state, compared to the aqueous solution of iron potassium cyanide, the preparation difficulty and cost of molten cobalt iron carbonate composite salt are undoubtedly much higher.

If this was laboratory preparation, it would be easier to talk about.

After all, the amount required by the lab isn't much, and the model is different too.

Lab production mostly doesn't need to consider costs too much, obtaining the product can already be considered effective for such a method, and might even justify a paper.

But it's different in the industrial field.

The industrial field has to consider various real-world problems, put simply, it's about profit margins, so the simpler and cheaper, the better.

This is also the reason why substances like hydrochloric acid are produced differently in the laboratory versus industrial production — predicting some might say the syntax is mixed.

Thinking up to here.

Yu Yuanyong immediately made a decision:

"Attention all departments, let's try iron potassium cyanide first, if it doesn't work, we'll consider other substances. Get ready immediately!"

As Hanhua Group is a well-known heavy industry group in Huaxia, it's natural for the factory to have a considerable reserve of iron potassium cyanide.

Thus, very quickly.

A newly prepared high-concentration iron potassium cyanide was placed on the test bench as a substitute for catechol.

Meanwhile, considering that this time the key lies in the softening of the feedback band, with emphasis on locking the peak.

Yu Yuanyong specifically adopted a measurement method combining Fourier transform infrared spectroscopy and Raman spectroscopy, with clear targeting.

Half an hour later.

Yu Yuanyong calculated the cycle of the rotation equipment, and the second round of experiments officially began.

"Beep—swoosh swoosh swoosh—"

Another fifteen minutes later.

The report results officially came out.

Yu Yuanyong took the report, glanced at it hurriedly, then his face lit up with joy as he said to Xu Yun:

"Dr. Xu, the absorption peak shifted 40nm to the right after the iron ion injection, but the selective peaks at 530 and 1060 positions did not appear!"

"No doubt, your thinking is correct, the special liquid completely balanced the interference of the feedback band!"

Upon hearing these words.

Xu Yun and Lin Zhenhua immediately smiled.

Just as Yu Yuanyong said.

This report basically confirmed Xu Yun's...or maybe Old Su's line of thinking, indicating that transition metal catalysis is no longer an insurmountable obstacle.

As early as when they arrived at the laboratory, Yu Yuanyong introduced that their team had already overcome some pre-existing technical obstacles, halting at the molecular sieve step.

And passing the molecular sieve, the only remaining problem was the directional cyclization equipment issue.

Indeed.

Directional cyclization is considered the final barrier, with difficulty possibly higher than all previous stages combined.

But at least for the overall situation.

Having only one major problem left is surely many times better than having a whole slew of issues.

It's like in online games.

Before formally attacking the boss, most players would first clear out the minor mobs and elite monsters, then focus on the boss as the singular target.

Of course.

Before launching the final general offensive, Yu Yuanyong and his team still have another issue to resolve first:

Which is how to adapt transition metals to the lowest-cost metal lanthanum.

However, this problem belongs to the realm of pure industrial optimization, beyond the capabilities of Xu Yun and others.

Furthermore, specific optimization won't yield results in a short time, taking at least more than two days.

Thus, after a simple handover.

Xu Yun and his team temporarily left the lab, taken by Zhao Haiyang to the Hanhua Group's guesthouse.

The Hanhua Group's guesthouse was a newly renovated eight-story building, not luxurious inside, but appearing rather imposing.

The specification for single rooms was a 1.8-meter bed, no bathtub in the bathroom, and besides some basic facilities, there was just a desk in the room.

The curtains in the room were electric, and the bedside table had a Xiaodu device for voice assistance.

As Lin Zhenhua previously mentioned, the room's soundproofing was exceptionally excellent:

Xu Yun played a recording of a friend snoring to ward off evil in the next room, only to find the sound couldn't get through.

In general.

It could be considered standard four-star quality.

However, instead of choosing to take a shower and then rest for a while, Xu Yun met with Old Su outside after placing his luggage.

Then he instructed Tang Li on some matters, and took the vehicle prepared by Zhao Haiyang to Yong City high-speed rail station.

The destination they must reach was quite clear:

First to Zhenjiang. 𝒻𝑟𝘦𝘦𝘸ℯ𝒷𝑛𝘰𝓋ℯ𝘭.𝘤𝘰𝘮

Then to Five Continents Mountain.

Finally arriving at...

Su Song's Tomb.
