Supercavitation refers to the phenomenon where a moving object's surface becomes surrounded by a layer of bubbles when its speed increases to a certain level.
This technology was also being developed for military applications.
Especially for naval forces—if this technology could be successfully applied, it would provide a revolutionary improvement to naval capabilities.
For example, supercavitating torpedoes, which used supercavitation technology to reduce navigational resistance, could travel at extremely high speeds underwater.
If the enemy didn't have breakthroughs in this technology, once locked onto, they would be completely finished.
In this world, this technology had actually begun to be applied, though it wasn't yet perfected. Even now, they hadn't successfully developed it for deployment.
Therefore, major powers were investing vast funds and resources in this technology, competing to complete development before other countries.
Once mastered, the ocean would be equivalent to the developing country's backyard—control of the seas would be seized and dominated.
So what if supercavitation technology wasn't just applied to torpedoes, but also to submarines?
This would be extremely terrifying—such submarines would become ocean overlords.
And this technology was currently on a laptop computer—complete technology.
This was the gift Ejie had brought as trade.
This was also one of the few STCs he had obtained that he could open and understand the contents of himself. Its core design looked like a large submarine-shaped USB drive.
This USB interface was designed as a universal interface.
That interface was like soft crystal clay—any connector could be plugged into it.
Brought to this world, it could apparently be read directly.
Such technology was basically a toy in Warhammer—militarily almost useless.
"Phew—"
Tessa inhaled and exhaled, because she had been looking so intently that she had forgotten to breathe, only stopping her browsing when she felt suffocated.
Only by personally touching this thing could she know how exaggerated and outrageous what Mr. Ejie called an STC really was.
Tessa's somewhat willful insistence on participating in this mission had two reasons.
On one hand, it was for livestreaming. According to Mr. Ejie, the plot would encounter exciting developments if it continued this way.
If she could livestream at close range, the effect would be best, and she could also earn energy coins.
On the other hand, Tessa felt she couldn't always huddle inside the submarine—she also wanted to truly participate in the brutal front lines.
Of course, she was self-aware of her combat abilities.
So for the next few days, she directly commissioned Mr. Ejie to give her hellish training too.
Ten days couldn't make her a true warrior, but at least it could improve her considerably.
If she encountered sudden assault situations in the future, like the submarine being invaded and facing enemies, she wouldn't be completely defenseless.
One reason for not choosing SRT's AS combat team members to train her was that they would probably be considerate of her status and hold back.
Regarding the possibility of submarine invasion, Mr. Ejie's knowledge of the plot confirmed that the assault submarine TDD-1 would indeed face invasion.
There were traitors within Mithril who would serve as inside agents to let enemies in, nearly causing the assault submarine TDD-1 to be captured.
Among the betraying members, there were some in Mithril's Pacific Fleet SRT, though not among the three currently on this mission.
The traitors were among the remaining members.
Since Mr. Ejie said the plot wasn't very clear about the traitors' names, just listing all the remaining members' names might trigger recognition.
Finally, they narrowed it down to two members: one named Guan Binbu, and one named Jordani Gang.
This was a real problem!
However, there was currently no evidence of betrayal—they might be bought off later.
But from today, these two would definitely be listed as key surveillance targets.
Furthermore, the betrayers might not be limited to just these two.
So Tessa's coming out this time also had this reason—the lieutenant colonel and major wanted to conduct a deep investigation within the submarine.
To avoid hidden enemies becoming desperate and lashing out at her, they had her accompany the mission.
Suddenly, Tessa's body stiffened because while relaxing herself and stretching, she accidentally pushed her hand onto the face of the person beside her, making her blush and feel embarrassed.
"S-sorry."
"It's fine, don't mind it."
"Um, this is a bit unfair."
"A bit unfair?"
Ejie looked somewhat confused at this bashful beautiful captain girl.
"I mean the trade—we're getting way too good a deal."
The gift he was giving her was vastly different from her return gift.
Like him giving her a gold submarine model she couldn't even lift, while her return gift was a plastic model.
This was too much—it made her feel undeserving.
"Don't feel like you're getting too good a deal. I might need your help later and will greedily take it back."
"Mm."
"Speaking of which, Tessa, what kind of deal did you make?" a voice interjected.
"You want to know?"
"Mm."
"After knowing, I'll have to silence you—"
Tessa said very frightening content with a sweet smile and sweet voice, making Sergeant Kurz, who was driving, want to laugh—but couldn't.
Because at this moment, Tessa had entered her dignified captain mode.
Now, the group had already left the submarine and come ashore, driving toward their arranged lodging.
They would probably arrive around eight in the evening.
Her gaze fell on the laptop again, and Tessa continued absorbing the knowledge above, later combining it with her understanding of technology to redevelop new submarines.
Or upgrade current submarines.
So, clicking on new content—
"Huh?"
A video popped up.
As the video played, some children appeared, probably around second grade elementary school age by local standards.
These children wore what seemed like military uniforms, then sat at very sci-fi computers—like holographic computers that could be operated in midair.
The children operated these, constructing something.
As the video continued, there were scene changes, and finally the children boarded submarines they seemed to have built like building blocks, preparing to compete in the ocean.
Uh!
How to put this—it gave Tessa the feeling of watching some TV toy commercial that could improve children's thinking abilities through various toy combinations.
This current video gave her the impression of this type of advertising.
"This video feels like an advertisement."
She couldn't help muttering.
"Remove the 'feels like.'"
Ejie directly confirmed it for Tessa.
That's right, what he had brought was an STC from a toy company.
"Ah?"
Tessa was stunned—it really was an advertisement.
Though this didn't seem too strange, since many countries' military contractors also advertised.
However, when the video reached its end and showed what might be a spokesperson or invited celebrity, Tessa was dumbfounded.
This was actually a children's toy company advertisement!
