Chapter 630: Strange Dossier

After listening to North Carolina's report, Qin Ge and the others fell silent.

You should know they had just finished an operation to seize a Siren base and had paid a considerable cost.

"It's hard to imagine that a single attack could completely destroy a Siren base—what immense strength!" Weineituo said in surprise.

"Hehe, compared to that, I'm more interested in the fact that this world has indeed seen some changes. And the appearance of such powerful shipgirls—who knows what will happen in the future?" Ou Gen Qin Wang smiled, biting his finger.

"You should have felt it too—after the world changed, it's as if the shackles that bound us have been loosened. After these few battles, I can feel my strength increasing, albeit slightly, but it's far stronger than before."

"Hmm, indeed, I also feel this sensation. I previously thought only I had it, but if you all have experienced it as well, then it shows this is a result of the world's change." Lisailiu nodded, agreeing with Ou Gen Qin Wang's statement.

"Is that so?" Qin Ge couldn't help but frown. "The changed world, the opened shackles, the emergence of new-type Sirens and unknown Siren elite units, as well as the appearance of unknown shipgirls."

All of this has appeared in this Siren Tide; it seems this is the Sirens' plot this time.

But why is that shipgirl unwilling to communicate more with us? With such formidable combat power, she should be able to wipe out the Sirens in this world directly.

"I can't say for sure, but something must have happened here." Ou Gen Qin Wang smiled. "However, the commander doesn't need to worry—although the sea is vast, as our strength grows we will eventually reach that level, and then we will know exactly what the cause is."

Listening to Ou Gen Qin Wang's words, Qin Ge nodded involuntarily. Just as he was about to speak, a figure appeared on the command ship.

"Sorry to interrupt your meeting, but we found a special document in the Siren base that I thought would be useful to the commander, so I brought it over right away." Hai Lun Na stepped forward, apologetically addressing everyone.

Qin Ge waved his hand. "No problem, Hai Lun Na—what did you find that made you rush over?"

Hai Lun Na directly took a data disk from her Ship Equipment Space and handed it to Qin Ge, saying, "I've copied everything inside; the commander can review it."

Qin Ge took the data disk and casually passed it to the Enterprise beside him. The Enterprise was very familiar with the structure of the data disk, and connected it to the command ship's command system.

After a brief operation, a document was projected onto the table, appearing before everyone's eyes.

"Social data: new progress in the historical doubtful case?" Looking at the projection on the table, the Enterprise doubted the reader's title.

Qin Ge quickly scanned the data; although some characters on the material had been blacked out, it still did not affect

"This is the data dossier on the Tunguska explosion." After reading it, Qin Ge said to everyone.

"The Tunguska explosion?" Soviet Russia looked at Qin Ge in surprise. "In my memory, the Northern Union region indeed experienced a major explosion, but I can no longer precisely recall where it was. Why is the commander so certain?"

Qin Ge smiled, pointing to a line in the dossier: "Although this part was deliberately blacked out, my world also experienced a Tunguska explosion, so I can immediately infer the timing."

Put together, it reads: At dawn on June 30, 1908, the present-day Northern Union Siberia Tungus region experienced a massive explosion comparable to a nuclear blast, completely destroying a forest area exceeding two thousand square kilometers.

This here refers to a hypothesis proposed after the Tunguska explosion, called the meteorite hypothesis.

In fact, besides this hypothesis, my world also has many other assumptions. The more famous viewpoints are the meteorite impact hypothesis, antimatter hypothesis, comet impact hypothesis, and ice body hypothesis, among others.

After all, no one knows the true cause of the impact; we can only infer how this great explosion came about through various hypotheses. But I find it strange: why would such a dossier be found in a Siren base?

This question plunged everyone into thought. Indeed, logically such a historical document could not appear in a Siren base, but now that it has, it must mean there is some reason behind it.

"I think the Sirens want us to discover something, so they deliberately placed such a dossier in their base." One side's Dao.

"What to discover?" Qin Ge frowned. "According to the Sirens' usual behavior, I feel this possibility is very high, but what connection does the Tunguska explosion have with this world?"

Could it be that the cause of the Tunguska explosion was the meteorite striking Earth and producing Cube crystals? That's too far-fetched.

Qin Ge's seemingly complaining remark made all the shipgirls' eyes light up. Zhenhai smiled and said, "If what the commander said is true, then is this Tunguska explosion related to the Cube?"

"Huh?" Qin Ge froze, then immediately said, "Don't just believe what I say because you heard it; I was merely complaining just now."

"But besides this, what other reason could cause the Sirens to place such a seemingly unrelated, weightless dossier in their base?" Zhenhai smiled.

"Hiss..." Qin Ge inhaled a breath of cold air. "If that's truly the case, perhaps the Sirens mean for us to explore the essence of this incident? Why don't they just tell us directly?"

"Perhaps they think we're unqualified? Or maybe the result is too unbelievable?" Ou Gen Qin Wang chuckled lightly.

"These cannot be confirmed yet, and the dossier is marked 'one,' indicating that besides this dossier, there may be a second or even a third."

"As long as we collect enough of them, we can fully reconstruct the truth of this matter." Enterprise said to Qin Ge.

"Well, it looks like we've added another task to our future missions." Qin Ge shrugged. "But I'm curious whether this world has a Tunguska explosion."

The shipgirls present looked at each other, then simultaneously shook their heads.

"My lord, we usually focus on combat; historical doubtful cases like this are outside our concern. If it weren't for this dossier, perhaps we wouldn't even know what the Tunguska explosion is." Tiancheng said somewhat helplessly.

"Well, it seems we need to find time to inquire whether this world has a Tunguska explosion." Qin Ge smiled and said.
