At this moment, Shu Qin looked at Chen Sixuan and whispered, "Can we do something now?"

Chen Sixuan shook her head with a frown and said, "I don’t know, regarding deep diving... I have no experience."

"None of us have experience." Qian Deli pointed to various maintenance robots operating in the air and said helplessly, "We have to rely entirely on these robots and Viola. Once in the sea, we can’t run or fly. Exceeding 3000 meters, even our power armor can’t withstand it."

"KIKI and Ryuji’s telekinesis shield should be fine, but I believe the least of our worries is this issue." At this moment, Luo Yang said, "With Brother Lin’s mechanical superpower and Silent City’s technology, I’m completely confident in the Infinity."

Xiao Yuan also nodded nervously and said, "Me too."

"I think we also need a contingency plan." Ning Jing said at this moment, "Our train is okay on land, but underwater, it’s too long, and the carriages are dispersed." She looked at Chen Sixuan, "There are people from Hawk Sea Group now. Just in case, we should best split into teams to prepare for escaping underwater or, in other words, having people to look out for each other."

"Okay." Chen Sixuan replied.

In the rear carriage, Sha Sha confirmed that the "Flying Peach" was firmly locked onto the bracket, and the hydraulic lock made a heavy "click" sound.

"Alright, it can’t be used underwater, but someday I’ll transform you into an interstellar boat, or perhaps join with Brother Lin’s big mecha, then you’ll look much cooler~"

Satisfied, Sha Sha looked at her partner, then prepared to return to the front carriage. As her fingers just left the cold metal bracket, ready to turn around, a faint, unsettling sound penetrated the thick train body and the star dust crystal glass of the porthole, seeping in from the unfathomable darkness below.

’Gurgle~ Gurgle...’

It wasn’t the sound of seawater hitting the train body, nor the hum of the propeller’s operation. It was a sort of rustling scrape, as if countless tiny, hard objects were moving against the high-energy structural metal pressure shell that underpinned the bottom of the train.

The sound was very light, mixed with the mechanical noise of deep diving mode and the sound of surging seawater, almost indistinguishable, but Sha Sha’s nerves instantly tensed, and a chill shot up her spine. She instinctively bent down, her ear almost touching the cold alloy floor. Now, they were in the water, and everyone knew the underwater was mysterious and unpredictable. Hearing such a sound at this moment made her instinctively alert.

"You heard it too?"

Just as Sha Sha was fully focused, a voice suddenly broke the quiet space in the carriage, startling her whole body. She looked up to find that Monica was now at the entrance of the cabin.

She wasn’t wearing the heavy power armor, only an inner liner suit, but at this moment, Monica’s eyes emitted a faint glow, clearly having activated her sound wave superpower.

"It’s right below."

Monica’s voice was extremely low, devoid of her usual laziness or teasing; her gaze was sharp like a knife, piercing through the porthole towards that abyss of inky darkness that devours everything.

"It probably hasn’t discovered us yet. Judging by the size of the sound, it could swallow our train in one gulp."

"Hiss!"

Upon hearing Monica’s words, Sha Sha instantly sucked in a breath, a chill rising from her feet.

"Damn, Brother Lin hasn’t returned yet."

In the No. 8 living carriage, Miao Lu, Sun Yuzhen, and others were assisting the people from the Hawk Sea Group with temporary refuge. These people were arranged in carriages Nos. 8 to 9, and Vanessa was still somewhat at a loss at this moment. After all, it was her first time standing on a train floating in water centimeters deep. If it weren’t for watching this group of versatile Infinity members, she’d even think she was dreaming.

Inside the carriage, the crowd surged, under the warm yellow emergency lights, Shi Zhi was using her superpower to help Ah Bai try to make him less nervous. Nearby, Xiao Qing came over and said to Ah Bai, "Coward, pull yourself together. We all need your sensing ability in the sea. Don’t let Captain Lin down."

"Okay... okay." Ah Bai nodded abruptly. From his tone, it could be heard he still felt great fear at going into the sea, but having followed Lin Xian through many big events, he wasn’t in a state of complete panic.

"Being scared is normal. The more you see, the more you should stay in awe." Shi Zhi comforted him. As someone also possessing sensing abilities, she deeply understood Ah Bai’s response.

Unexpectedly, just as her voice fell, as she raised a cup of water, her actions suddenly froze, her brows furrowing deeply, Ah Bai almost simultaneously lifted his head, and their eyes met.

"...Something’s wrong!"

Ah Bai’s pupils slightly contracted, his fingers gripping the cup tightly, turning them white at the knuckles.

"What’s wrong?" Xiao Qing, seeing their expressions, immediately sensed a hint of danger, her body tensed instantly, and her superpower wave began to surge.

"There’s something..."

"Under the train!"

At this moment, Ah Bai and Shi Zhi spoke in unison, their gazes seeming to pierce the carriage walls, directly into the deep ocean waters.

"It’s quite large, moving through the underwater submarine channel!" Shi Zhi’s face visibly became tense.

Xiao Qing’s gaze sharpened, just about to speak.

"Everyone—!"

Monica’s voice suddenly rang out in the communicator, "Be careful, an unknown creature has been spotted underwater, those monsters might have already entered the submarine port."

Carriage No. 3 fell into a silence so deep that even Ding Junyi’s manipulation of vines to extract blood crystal dark energy paused for a moment. She looked around, then at the Silver Dragon Ten Thousand Mistakes in front of her, wondering if it was her actions that had attracted them?
