As soon as they exited the elevator, they felt the temperature around them increase by more than a degree, a hot wind rushing towards them, and the roar of the exhaust fans.

The environment suddenly turned dark, with a faint and indistinct red light flickering not far away.

The Shrine is a super-large server, deeply buried underground, requiring a powerful cooling system for support.

It is impossible to directly reach fifty floors underground; they still need to traverse the complex underground network to arrive near the Shrine. The electricity needed by this server network is unimaginable, with a large number of energy plants surely growing in the unseen underground.

The red mist drifting in the air must have been emitted by those energy plants.

In the darkness, the two groped their way forward; through the glass skylight, they could already see the outline of the Shrine deep in the well. A giant mechanical sphere covered in thick pipelines, pulsating with a fixed frequency of red light like a living creature breathing.

The interior of the deep well is filled with mercury, known for its excellent thermal conductivity. The upper exhaust facilities rumble continuously, extracting the rising mercury vapor and discharging it through pipes to the surface.

Under the flashing red light, the two walked in front of the towering glass curtain wall, surrounded by gigantic buildings that all turned into silent gray shadows at this moment.

"Are you hot, Four-leaf Phoenix Tree?" Zhou Zhao asked.

"Isn’t that obvious?" Four-leaf Phoenix Tree responded, speechless.

"But why do I feel suddenly a bit cooler, did you feel a wind come through, like the kind that blows across a field of rice paddies?"

Four-leaf Phoenix Tree sensed something was wrong.

At the same time, rapid footsteps could be heard in the darkness, like the beat of war drums, becoming increasingly denser and louder, someone was approaching them!

A cold light tore through space, instinctively, Four-leaf Phoenix Tree reacted, raising and swinging his hand vigorously, a Willow Leaf Blade with a white glow at its edge shattered before his eyes, refracting the cold visage of a young girl.

In just an instant, he felt the domineering power coming from the opponent’s Great Tachi, the force traveled through his palm into his entire body, crashing through him, making his body ache all over.

Four-leaf Phoenix Tree was forced to fly back.

"Four-leaf Phoenix Tree!" Zhou Zhao called out softly.

Zhou Zhao quickly understood what the other had gone through, the figure in the darkness aimed the blade at him, and in the blink of an eye, swiftly came forward, her palm pressing against the hilt of the Great Tachi, her right hand protecting the blade, deftly slashing diagonally.

Someone attacked them!

Before this, they hadn’t even detected a trace, that person’s ability to conceal her presence was extremely strong!

In this moment, on the thirtieth level below ground, there was someone besides them!

Who could the opponent be?

Zhou Zhao thought of the intruder who initially broke into the Ausen Technology Innovation building.

Zhou Zhao cursed under his breath, a champion’s hand appeared in his hand, raised to protect himself, but he still couldn’t feel the blade’s fall until his body was struck by a powerful blow, a long yet strong leg swept across his chest.

Zhou Zhao felt that what hit his chest wasn’t the girl’s leg, but rather a moving train!

His consciousness momentarily disjointed, his chest nearly caved in instantly, his ribs shattered, and blood flowed from his mouth and nose.

The opponent’s speed was so fast, she could catch up with the flying-away Zhou Zhao within a breath’s time, seeing two streaks of golden light flash by, Zhou Zhao’s combat senses were strained to the utmost, the Ivory Door appeared behind him, and as his body fell into the Ivory Door it closed in an instant, but was soon sliced into countless parts by the pursuing blade.

The second streak of golden light came from Four-leaf Phoenix Tree, who responded quickly, immediately deploying the Divine Speed Power to the limit, grabbing the falling Zhou Zhao from another Ivory Door, then taking off in a frenzied sprint.

In the darkness, electric light surged past.

The girl didn’t immediately chase after them, her silhouette with the poised blade stood afar watching them, the interplay of light and shadow illuminated her black Sword Dao uniform in blood red, as she slowly turned away, just like a hunter lurking once more in the darkness, waiting for the next hunt to commence.

Because of the long blade, the Great Tachi is more visually impressive than practical for combat, barely anyone can wield such a weapon; in their memory, only one person.

"It’s Su Sui," Four-leaf Phoenix Tree concluded.

"Damn it!" Zhou Zhao cursed.

Encountering her in such a cramped environment is truly like seeing a ghost.

"So it’s her."

"She wouldn’t have come specifically looking for us," Four-leaf Phoenix Tree, collecting himself.

"Clearly, she just learned of our presence, and the attack she launched was merely a probing assault; if we accidentally stepped into her Tu Domain earlier, we’d be in trouble now."

Four-leaf Phoenix Tree had previously crossed swords with Su Sui, discerning her ghostly presence within her domain. Her ability restrained him significantly, for within the Tu Domain, her speed could rival or even surpass his, and the fact she didn’t chase further could only mean one thing.

That encounter was unexpected for Su Sui as well.

"Has Light Chasing Garden also learned about information regarding the Black Box?"

"Unclear, she entered this building before us, yet arrived here simultaneously; her initial purpose probably wasn’t to head directly to the Shrine. She must’ve been gathering information inside the building for some time."

"Then she likely doesn’t know about the coordinate situation," Zhou Zhao spoke up.

Upon hearing this, Four-leaf Phoenix Tree suddenly stopped.

The corridor ahead was simultaneously cut by dense white knife light, the blade marks slowly emerged, exploding instantly, reducing to a collapsed ruin.

The alarm resounded above, flashing red lights below, as the figure of the black-haired girl slowly stepped out, the symbols of the crane and rice grain gradually revealed on her Sword Dao uniform, a Great Tachi smoothly traced a semicircle in the air, just placed before her.

A bright red flame ignited from the tip of the blade in an instant to the long blade body, illuminating Su Sui’s face.

"This girl..."

"You must’ve heard everything then?" Four-leaf Phoenix Tree asked.

"Yes," Su Sui replied. "What are the coordinates?"

"How about cooperation?" Four-leaf Phoenix Tree did not directly answer but said,

"It’s unclear what’s happening inside the Shrine, the rampant data storm is dangerous. By cooperating, we all have a chance to approach the coordinates."

"I can disable you two and then threaten you to reveal the coordinates just the same," Su Sui said.

Zhou Zhao cursed internally.

So, this girl appears silent and reticent, like a mature and stable executor within a team, but actually, she’s a hopelessly bloodthirsty killer at heart!

"And why do you think you alone can defeat the two of us?" Sweat began to bead on Four-leaf Phoenix Tree’s forehead.

Neither of them was very skilled at close combat; if Yu Lan were here, she would have the strength to directly confront the girl.

"It’s hard to say," Su Sui said expressionlessly, "but now it’s uncertain."

The two glanced around, and sure enough, rice grains, a person high, had somehow appeared around them, swaying in the silent wind.

Taking advantage of the conversation, Su Sui had deployed her Tu Domain!
