Deep Blue Eye

Yang Ning wasn't in a hurry to meditate—after all, it wasn't dark yet.

Although meditating during the day was possible, it was hard to enter a meditative state when one's spirit was fully alert.

So Yang Ning decided to first build himself a cheat device.

After all, he had fused with the Dragon Pearl and awakened superpowers over electricity, water, and wind.

Having superpowers and not using them for research would be like becoming a Wakandan wielding a spear!

Yang Ning wanted to create a Deep Blue external display—one that integrated a telescope, microscope, and screen into a single unit.

That way, his communication with Deep Blue wouldn't require entering the Spirit Realm. Although time flowed differently inside and outside the Spirit Realm, if a powerful enemy targeted him, even a single second could be fatal.

The material for the display would be water.

As everyone knows, when water molecules are confined to sub-nanometer spaces, the orbitals between two oxygen atoms and two hydrogen atoms from two water molecules overlap, creating a many-body nuclear quantum effect. This effect provides a channel for ultrafast electron transfer.

And two linearly superimposed oxygen atoms exhibit quantum topological excitation, producing bright fluorescence.

The excitation conditions were simple—anything from blue light to ultraviolet could trigger it.

In short, if the display were placed on the retina, simply opening one's eyes would allow external light to power it normally.

Alternatively, electrical current could also excite it.

Structured water wasn't easy to make—water molecules don't obey orders—but Yang Ning controlled water flow as naturally as breathing. Experimenting in the Spirit Realm consumed no stamina, so he could try endlessly.

As long as he succeeded once, the Spirit Realm could record and replicate it infinitely, achieving the goal.

This wasn't some lofty "once proven, forever proven" concept—it was the most basic principle of science: reproducibility.

By two in the afternoon, a clump of luminescent structured water had been created.

Watching the structured water glow with alternating blue, white, red, yellow, and green light under an electric current—like holding a neon sign—Yang Ning let out a breath of relief.

This step was the hardest; the remaining functions were much simpler.

A microscope and telescope were just applications of convex and concave lenses. Yang Ning finished them in the blink of an eye.

The software on the display was all provided by the Spirit Realm, so Yang Ning didn't need to worry about that. Two minutes later, a water mist less than 0.1 microns thick coated his eyes.

It had no effect on his vision—after all, the tears from a single blink were thicker than that.

But tears didn't glow.

Naturally excited structured water emitted green light, but that method was uncontrollable, so Yang Ning chose electrical excitation instead.

Ordinary electrical excitation produced blue light. Yang Ning kept adjusting the current's properties, watching the structured water flash through colors like a neon sign, until he finally determined the excitation method for every color.

This display skipped black-and-white, green-blue screens entirely, evolving straight into color.

He opened his eyes and looked around, first capturing the scenery as an image, then fine-tuning until the colors matched nature perfectly.

"Perfect!"

Yang Ning blinked. Next, he tested the telescope function.

He looked at the distant waterfall, and with a thought, the waterfall zoomed closer and closer until it seemed right before his eyes!

Unfortunately, the light the field of vision could receive was limited, so things too far away were still a bit blurry.

But that didn't matter. Yang Ning adjusted the surrounding water mist into invisible micro-droplets, then had them focus light into his eyes. Now, the waterfall he saw was truly the waterfall.

He could even see the splashing droplets clearly, along with fish carried down the waterfall—their scales, even parasites!

Keep in mind, his position was 330 kilometers away from that waterfall!

And this wasn't the limit—because his control was too fine, he hadn't even approached the upper bound of his water manipulation ability.

Not just 330 kilometers—if he operated at full power, he could see everything within a thousand li, even ten thousand li, as clearly as the lines on his palm!

But being able to do something didn't mean he should. He wasn't confident he could handle the consequences of exposing his abilities. Although his observation relied on receiving light rather than emitting it, so theoretically, no one would notice.

Who would suspect someone a thousand li away was watching them through a telescope?

But mortals had sixth senses; immortals' were only stronger. To be safe, it was better to stay cautious.

Using the microscope didn't have this problem, but unfortunately, the microscope on his eyes was inferior to the one in the Spirit Realm. The Spirit Realm's could see cell nuclei and DNA, while his eye-mounted microscope could only reach the cellular level.

Still, even that met the standard Yang Ning had envisioned.

[Deep Blue Eye] was now finalized!

"What's this?" Yang Ning casually grabbed a blade of grass by the river and asked.

"Unknown. Not recorded in the archives."

"No way, the Vast Universe Records didn't mention it?" Yang Ning looked around. This blue-tinged white grass grew everywhere along the riverbank—it wasn't exactly a rare plant!

"The Vast Universe Records only catalog various spirit herbs. Perhaps this grass has no value," Deep Blue said.

"Makes sense!" Yang Ning nodded. This was a cultivation world, where everyone pursued power.

No one had even invented the Curved Shaft Plow—who had time to study plants?

"That's it!" Perhaps due to the mental clarity from meditation, Yang Ning suddenly understood why this world had remained feudal for hundreds of thousands of years.

Because those in charge were feudal landlords. They didn't need to farm themselves—they wouldn't starve—so why would they have any motivation to reform agricultural tools?

Wouldn't it be better to just study, pass the imperial exams, and become an official?

As for ordinary farmers, they couldn't even dream of inventing or creating anything. Day after day, they couldn't eat their fill—only hunger, nothing but hunger, with no time to think about anything else.

As for those one step higher on the social ladder, all they thought about was how to join a cultivation sect, so they would never lower their heads to look at the patch of land beneath their feet!

"And then there's someone like me—even if I had the talent for invention, what draws me most is still cultivation!"

After all, inventions can't grant immortality; a hundred years later, you're still just a handful of yellow earth. But cultivation—that can truly let you live for thousands of years!

What's the point of leaving a name in history? Isn't it better to just keep living in history myself?

"What's the use of thinking so much? I'm just a small fry—can't even control my own fate, so how can I talk about changing the world?" Yang Ning shook his head.

I examine myself three times a day—every time I think of the gap between myself and true powerhouses, it adds another dose of motivation to cultivate!

"Deep Blue, record this thing. Call it Blue Silver."

"Hm?"

"Ahem, call it Water Blue Grass!" Yang Ning didn't want to court death.

This thing was useless in the Cultivation World, but not necessarily in the scientific world. Many breakthroughs in technology, even entire civilizations, sometimes came from an unremarkable plant.

Like rubber, corn, or potatoes.

In his spare time from cultivation, he went around searching for plants, animals, and even ores to file away. He wasn't Shennong, so he didn't dare taste them raw, but recording their appearance was fine.

Vast Universe Records was a travelogue, not a specialized botanical record. But alchemists must have studied plants and herbs extensively, and artifact refiners would research ores too—they probably had more professional books on hand.

Recording it now might come in handy later.

Anyway, he had nothing better to do. Aside from Tuo Buchuan, he looked for everything.
