I changed the timeline with the game.

Chapter 1141 Another 'Death'

The girl didn't see the so-called 'immortality' that Su Wen spoke of as a bad thing, but they shouldn't come at the cost of sacrificing an entire city. So, after receiving a positive reply from the handsome scholar, Chie closed her eyes and began to expand her spiritual perception.

She has to find them!

From a psychic perspective, Natsume Chie's perception, compared to his "Appraisal Vision," is more like the difference between three-dimensional perspective and sonar.

Moreover, Su Wen will bear the side effects.
Therefore, although the lineage of the girl is still relatively vague, it can be expanded blindly.

that's it,
The sensory network of the psychic lineage spreads deeper and deeper like spider silk.

The girl's consciousness traversed the slime-filled tunnel, avoiding the assimil-like swarm of flesh, and finally pointed to the abandoned control room three hundred meters ahead.
—There were unusually strong psionic fluctuations there, as striking as a lighthouse in the darkness.

But as her fingertips trembled slightly as she pointed in that direction, the girl's senses abruptly disconnected.

because:

“An extremely large black tide is surging towards us.”

Natsume's tale of Chie is still unfolding.
In the distance, the muffled thud of the railway tracks could be heard.

Like an underground river suddenly surging, black water began to seep out along the gaps in the tracks, carrying the scent of rotting flowers and the stench of rust, slowly advancing towards the platform.

But in an instant, this slowly sinking scene unfolded like an apocalyptic torrent:

The deep black river, transformed from sound into a visually tangible apocalyptic scene, surged forth from the depths of the tunnel.

The surface of the Kuroshio Current gleamed with a cold, oily sheen.

It looked like a swarm of thousands of rotting snakes writhing.

The mechanics had prepared a contingency plan in advance to deal with this situation.

He carefully calculated the corresponding depth, then took out a magnetic track rangefinder and quickly drew a three-dimensional cross-section of the subway in his palm.

However, the numbers flashing on the rangefinder screen showed that the Kuroshio was advancing towards the platform at a speed of 3.2 meters per second, reaching a depth of 127 meters underground.

"Damn it,"
We need to find a safe haven quickly to escape this black tide.

Before the man could finish speaking, he threw out a quick-deployment device he was carrying:

It was a silver cube. After pressing the red button on top, the cube instantly unfolded into a translucent energy barrier with pale purple electric arcs flowing across its surface.

But this was not enough to stop the surging Kuroshio.

The crest of the black tide had reached within two meters of the barrier, and the viscous liquid was corroding the barrier's surface at a visible rate.

The barrier emitted a hissing sound, its brightness began to diminish, and the electric arcs became sparse.

So the only remaining subway maintenance worker had to lead them down another route. The man who had just spoken pointed in a trembling voice to the ventilation duct on the left:

"Climb up from here,"
It leads to the air-raid shelter a little above, but I'm afraid there might be more monsters there.

"They're just transformed monsters, it doesn't matter."

The mechanic followed a few other people up.
But in the blink of an eye, they could no longer see Su Wen and Natsume Chie. All they could see was the empty platform and the approaching Black Tide. Su Wen and Chie seemed to have vanished into thin air, and even the fluctuations of their spiritual energy disappeared without a trace.

As for the man who had initially mocked Su Wen, he said with lingering fear:
"Two inexperienced people,"

Even if they're just [Guides], Tier 1 is still Tier 1. They're still dreaming of participating in high-risk diving operations. Let's get going.

But the moment they left,
That scene, which they didn't add to, seems to have been completely imprinted in the eyes of countless viewers who had seen the film "Blue Dawn":
The handsome scholar slowly drew a deep blue longsword from thin air.
The sword's blade shimmered with starlight, and ancient runes were engraved on its hilt.

Subsequently,

Su Wen simply shook his head silently: "The Black Tide is also a tide."

In an instant, he lightly raised his sword and completely sliced ​​through the black tide.

The azure blade, like a crescent moon, tore through the viscous black tide, causing the putrid mist to dissipate in the sword's wind, revealing the railway tracks below, corroded by the black tide.
The rusted metal surfaces were peeling away at a visible rate, leaving only a cold, gleaming alloy skeleton. But this was not the end.
The invisible storm even tore the rails apart, and electromagnetic pulses carrying metal fragments exploded in the tunnel.

Silvery-white arcs of electricity shot up from both sides of the broken rails, emitting a piercing metallic tearing sound.
It was as if the entire track had been torn open by the claws of some invisible behemoth.

This time, Su Wen didn't even use the mythical properties of the [Watcher's Sword]. He deliberately concealed the starlight patterns on the blade, retaining only its basic sharpness.

This was to conceal their identity.

After all, the open use of high-level psionic weapons in contaminated areas could easily attract direct intervention from the "Revivers".

He is currently laying the groundwork for the first clash between two civilizations.

Therefore, after taking action, Su Wen even chose to throw his diving token into the wreckage of the Black Tide.

As he watched the digital token gradually corrode and turn grayish-white, his vital signs status in the dive list also changed to "dead".

If Su Wen's original goal was to obtain more inside information about the sinking of Tokyo before the Night Watchmen did, then...

The information I have now is probably sufficient.

Aside from a few details that still require research and even time to delve into, he has already found the path he should take.

Now, the identities of the two 'dead' Bounty Hunter Association Deep Dive Special Agents may be even more necessary.

Su Wen leaned back on the bench in the wooden cabin of Lorenzriel Academy, turned his head, and looked at the [Stage Mission] in the upper right corner of the screen.

This also has a consequence:
He was no longer able to return with Natsume Chie via the normal descent route.

But Su Wen didn't care.

He has the opportunity to reload his save file, and the time projected into reality in the future has a high margin of error, therefore:
"It's time to choose some more adventurous plans."

Chie,

"Take me to the border where you most clearly sensed that 'vast divine abomination.'"

"it is good."

The girl did not hesitate.

All she wants now is to believe in her teacher; she wants to save the Tokyo Metropolitan Subway system built by her grandfather, father, and even the entire long-vanished Natsume family.

At this moment, inside the B7 level pipes of the Tokyo Metro,

The emergency lights cast spiderweb-like patterns of light on the damp concrete wall.

The metal support, corroded by the Kuroshio Current, is oozing a silvery-blue viscous liquid that solidifies into crystal-like prisms in the dark.

The little girl's nodding motion was as light as a cherry blossom dampened by rain.

She pointed in one direction and then followed Su Wen's footsteps directly onto the rusted tracks.

As she moved forward, the scene before her seemed to consist only of Su Wen, yet it also seemed to overlap with her past memories.

It was as if she saw her grandfather more than ten years ago, surveying the site and revising the design drawings in this still unfinished pipeline.

They did different things.

But why do I feel so much the same way?

five minutes later,

As you go deeper into the pipe, a crisp sound like shattering glass suddenly comes from within.

As Chie reactivated her mediumial senses, her pupils suddenly contracted in the darkness; she sensed an unusual threat!
