Xingtie: My silly online friend is actually a raccoon!

Lu Ze suddenly realized a problem.

He turned his head and looked at Spark, who was sitting at the other end of the table, intently applying some kind of glittery nail polish to his nails.

"Spark, you actually have a drone? Why didn't you bring it out sooner?"

Spark didn't even look up, focusing intently on painting her nails, her tone languid.

"How am I supposed to know what you need if you don't tell me? Sparkle has so many amazing tools here, I don't even know what I usually carry with me."

Lu Ze wasn't blaming her.

This incident reminded him that in the future, he should always ask Spark first if he needs anything, to see if she can still pull out anything useful from her pocket.

He then glanced at the stable high-definition image on the screen and couldn't help but add a comment.

"The signal from this drone is really good; it can connect even over a hundred miles away without any lag."

This is also why he didn't initially think of using drones to monitor Tang Sanzang.

In his common sense, a drone's signal coverage is at most a dozen kilometers.

Spark looked up and glanced at him with a "who are you looking down on?" look.

"That's because it's equipped with long-range telemetry. Let alone a hundred miles or more, it can connect even if you're in Heaven and want to monitor the Underworld, or if you're in the Underworld and want to see what's happening in Heaven."

She pursed her lips, seemingly thinking that Lu Ze was underestimating the genius's invention.

Long-range telemetry was invented by Elijah Salas, the genius of the Club of Geniuses #56, to connect geniuses, but none of them were willing to use it.

This thing can ignore the imaginary number barrier of galaxies and the distance of light-years, and achieve real-time communication throughout the universe. It is equivalent to a cosmic-level long-range communication base station.

Even today, interstellar communication between entities such as Star Train and Interstellar Peace Corporation still relies on this fundamental technology.

"Remote sensing is just a small gadget we make on the spot, it's not worth much at all," Spark added casually.

On the other side of the Milky Way, long-range remote sensing has already been put into civilian use; it's installed in almost any communication device you buy.

The ignorant Lu Ze wisely shut his mouth, silently picked up his teacup, took a sip, and turned his attention back to the screen.

Since they dealt with Sha Wujing last time, they have been using this drone to monitor Tang Sanzang for several days.

It has to be said that this thing is really useful. They don't need to stay in the deep mountains and forests feeding mosquitoes with Tang Sanzang, nor do they have to worry about losing him or exposing their whereabouts. They can simply release the drone at regular intervals every day to keep track of Tang Sanzang's movements in real time, saving both time and effort.

Furthermore, Spark also mentioned that she needed to arrange some matters for the "next film set" in the vicinity.

When Lu Ze asked her what it was, she just smiled mysteriously and said, "You'll find out when the time comes."

At this moment, Spark finished painting her nails, blew on them, spread her hands out to admire them, and nodded in satisfaction.

Then she stood up, walked to Lu Ze's side, and held out her hand to him.

"Does this nail polish look good? Does it suit me?"

"?"

Lu Ze put down his teacup, looking somewhat puzzled, but still carefully examined those delicate, jade-like hands.

The ten fingertips were neatly trimmed and evenly covered with a bright yet understated true red nail polish, making the already fair fingertips even more eye-catching.

Lu Ze had just reached out his hand, wanting to get a closer look, when Spark quickly withdrew his hand.

"Want to touch? No way!"

Spark blinked at him, a sly smile playing on her lips.
