Doomsday: I Build an Infinite Train.

Chapter 451 Dive, Dive!
bass!
The massive Hyperion Directional Restraint Cannon fell from the Black Star Forge. This space-based weapon was the first time Lin Xian had used it since obtaining it from Shinji Mochizuki. The purpose he was going to accomplish was the same as what Shinji Mochizuki had previously planned to do by detonating the floating tower in White City...

Buzz!
The dome-shaped rock wall suddenly crumbled, and hundreds of thousands of black insects twisted into a giant drill and crashed down, like a torso made of snakes. KIKI immediately unleashed a psychic storm with both palms, and the front end of the insect drill exploded in response, but the scattered insect swarm instantly spat out a silver-green silk net to cover the two of them.

This time, KIKI realized the power of those threads and dared not confront them head-on. Instead, she raised her hand and forcefully tore apart a huge rock wall of the geothermal well. The ejected threads instantly melted through the boulder, creating a hole and spraying out dust and powder.

Meanwhile, on Viola's side, thousands of drones, like a swarm of insects, swiftly and rapidly moved above the geothermal well, their violent rays and high-energy impacts working together to brutally annihilate the insect-like creatures.

"Lin Xian!"

"nailed it."

Lin Xian manipulated the robotic arm to embed into the cooling fins of the reactor shell. The thousand-ton metal structure was suspended above the boiling magma pool under the protection of KIKI's psychic field. Then, he smashed the chain reaction module into the reactor core and then directly fixed the huge Hyperion directional confinement cannon above the reactor, forming a simple induction reactor device.

[Note: The enemy creatures' energy blasts are extremely destructive to the environment and metal devices, covering a very wide area. To ensure the smooth execution of the plan, the safety of the equipment must be protected.]

Viola then offered a reminder.

"Of course! Let's lure it away!" Lin Xian manipulated the robotic arm to directly attach the reactor to the cross-shaped base of the geothermal device, then called KIKI, and the leg thrusters overloaded and erupted, retreating towards the passage without hesitation.

At this moment, the black insects and snakes covering the dome began to frantically sweep towards Lin Xian and KIKI. From a distance, they looked like black water swimming in the air, rapidly twisting and dragging the insects all over the wall, constantly gathering them together, and coming all over the sky.

Viola followed behind the two to cover their retreat. Thousands of drones followed behind as if they were alive, providing cover and counterattacking at the same time. Under Viola's super computing power, all the drones seemed to have individual consciousness, able to monitor hundreds of thousands of targets simultaneously and disperse them to defend against the enemy. This alone was something Lin Xian could not do, and it was the scene that Lin Xian wanted to achieve by building a drone army.

[The upper-level sensors detected a large number of organisms approaching, with an estimated contact time of 4 minutes.]

Before they could dodge the black insects swarming from behind, Viola delivered an even more despairing message. Lin Xian gritted his teeth, raised his hand, and blasted open the half-collapsed passage with a mechanical cannon. Then, Kiki activated her psychic shield, and the two rushed inside.

Rumble.

Deep-water port, with turbulent waves.

The Infinite Train and the Abyss Nuclear Submarine floated halfway in the inky black sea, with eerie phosphorescent creatures drifting outside the portholes. Chen Sixuan stood in the Infinite Train's No. 2 carriage, her expression grim as she looked at the train's sentry system. In the nuclear submarine's command center, Ryan watched the giant red dot flashing directly below him on the radar screen, his hand still pressed on his headset. The other team members behind him were all holding their breath, and it seemed as if everyone in the cabin could hear each other's heartbeats.

"Lin Xian... Lin Xian..." Chen Sixuan continued to contact Lin Xian.

"The signal from the geothermal well is being severely interfered with." Ning Jing's voice came from the monitoring station in carriage 5, where she was monitoring the area with others in the building: "I suggest we don't act rashly for now."

"That thing is underwater, and we can't figure out what it is." Ryan, aboard the nuclear submarine, sounded quite troubled.

"It's at least Grade A or above, or even Special Grade. The Spirit Energy Detector detected extremely high dark energy fluctuations." The speaker was Erica from the Falcon Squadron.

"It seems they haven't noticed us," Gaddy said. "It's best not to make a move first, or we'll be in trouble if we get marked."

“It’s not a matter of marking now.” In the cockpit of the Infinity, Monica leaned over and looked at the black water outside the Stardust porthole. A strange tentacle with black and white rings slowly slid across the surface of the water. She said in a stern voice, “This thing is blocking our descent passage.”

Upon hearing this, the other key members on the communication band held their breath.

Chen Sixuan then spoke up: "Monica, Ryan, everyone get ready to make a move. We only have one path left!"

At this point, the Infinity had undergone deep-sea module modifications, rendering all onboard weapons unusable. To deal with the trouble, the only option was for the superhumans to intervene.

Just as everyone was on high alert, a violent explosion suddenly came from the upper level. Then the surface of the deep-water port began to boil violently. The underwater monster seemed to have set its sights on something. The dark seawater suddenly froze, the suspended phosphorescent microorganisms went out, and the sonar screen of the Abyss nuclear submarine exploded with blood-red ripples. At the same time, the Falcon Fleet and the crew of the Infinity heard the alarm sounding inside!
"coming!"

Boom! !
Between the Infinity and the nuclear submarine, the water surface suddenly bulged, and then a gelatinous tentacle with a diameter of over thirty meters burst out of the water with the power of a giant object. Thousands of tons of seawater slammed into the pressure hull of the nuclear submarine, and the hull slid sideways like a toy and crashed into the rock wall, the titanium alloy shell emitting a piercing groan.

Almost simultaneously, five pale tentacles covered in bone spurs wrapped around the third carriage of the Infinite, pushing the Infinite directly out of the water.

"Do it!"

Before the monster could even be seen in its true form after breaking through the water, both sides had already responded. A flash of cold air appeared above the nuclear submarine, and the turbulent seawater in the entire deep-water harbor suddenly froze rapidly. Then, it shattered under the monster's impact, and then solidified again, breaking into large pieces of ice.

On the Mugen side, Ryunosuke flew out of the hatch and immediately attacked in mid-air, severing the tendrils that were binding the Mugen. He also protected the nuclear submarine with his psychic waves. At the same time, three figures appeared on the pressure hull on the roof of the vehicle. They were none other than Fire Bro, Monica, and Ah Bai, three ability users with wide-range attacks. They immediately launched their attacks with the Flame Sword, the Laser Beam, and the Invisible Sonic Sword.

Boom boom boom!
The lights of the gantry cranes above the deep-water port flickered, and the entire hollow cavern was illuminated by flames and laser beams. The monster that broke through the water's surface was now only showing part of its torso. Its enormous body squeezed past the Infinity and the nuclear submarine, revealing a mutated creature that seemed to be a fusion of whale skull and deep-sea worm features. Millions of compound eyes rolled in the cracks of its skull, and its open mouth contained six spiral teeth stacked on top of each other, emitting a low-frequency hum that drew souls in.

The attacks from Huo Ge and his two companions struck the monster instantly, shattering its bio-force field. A huge hole burst open in its skull, spewing out a large amount of black blood. It seemed that only part of the monster's torso was visible above the water. After being attacked, it shuddered violently and began to frantically charge towards the passage above.

"Trying to run?!" Brother Huo pointed his sword, ready to finish off the opponent.

Seeing this, Monica's expression changed, and she immediately said, "Its target isn't us, it's above!"

"Lin Xian?" Chen Sixuan reacted and was about to say something when Lin Xian's voice finally rang out on the frequency.

"Dive! Dive!"

Before Lin Xian's voice had even faded, a violent earthquake began to occur throughout the submarine base. The water surface surged, the ground shook, rocks and cliffs collapsed continuously, and the upper level began to completely collapse.

"Lin Xian has been marked! Quick, control it!" Realizing this, Monica immediately checked her own marking status and, finding that no light was on, called out to Ryunosuke.

At this moment, the superstructure exploded violently, and the bizarre monster that burst out of the water surged out of the water. Its black and white body, hundreds of meters long, almost covered the entire underground space of the submarine's deep-water port under the lights, and its shiny skin made people's scalps tingle.

Ryunosuke took the lead, spreading his arms wide and using all his strength to try to control the thing. At the same time, a scorching high-temperature beam suddenly burst out from the smoke and dust above, accompanied by violent energy fluctuations that steamed the air, piercing a huge blood hole through the monster's head. Then, in a cloud of gray-black smoke, Lin Xian and KIKI flew out of the monster's blood hole, followed by Viola and the drone swarm that was now less than half full.

"Lin Xian, what happened?"

"There's no time to explain." Seeing that Brother Huo and Ah Bai were still preparing to make a move, Lin Xian flew directly to the Infinity without saying a word: "Get on board, let's dive."

"This monster?" Huo Ge exclaimed in surprise. The giant monster in front of him was still twisting its body and was obviously not completely dead yet.

"Never mind that!" Kiki shouted, "This place is about to explode, there's no time!"

Before KIKI could finish speaking, Monica had already pulled Ah Bai along and quickly followed Lin Xian into the inner cabin. Huo Ge looked down at the surging black water below, his expression changed slightly, he swallowed hard, and then quickly crawled in with Ryunosuke.

chi~
The outer cabin of the deep-sea submersible closed, and the inner cabin began pressurization. Upon returning to the Infinite, Lin Xian immediately arranged for Viola to...

"Increase pressure, descend rapidly!"

"Ryan, you guys follow behind."

"Understood." Ryan immediately ordered his subordinates, "Tilt 15 degrees, fill the main ballast tanks with water!" With a rumble, the submarine's hydraulic pumps emitted a muffled hum, the water injection pipes bulged instantly, and the hull began to sink.

Meanwhile, the Infinity train broke through the water's surface and plunged directly into the deep water. Everyone on board felt the ground suddenly tilt and even become vertical. Unlike a submarine that sinks horizontally, the Infinity was like a black dragon diving straight down. Looking out from inside the carriage, the portholes were immediately submerged in black water. At this moment, a metallic humming sound came from the pressure hull, and the thrusters outside the carriage roared, stirring up the monster's shattered limbs like mud, and quickly plunging into the water.

Boom! !
Almost the instant the two vehicles entered the water, the entire cave of the submarine base collapsed with a deafening roar. Boulder fell, and the writhing black and white sea monster was about to retreat underwater, but its shattered head was directly crushed by the boulder in the cave. At this moment, a large number of black water-like insects and snakes emerged from the cave entrance that originally led to the upper level and chased after Lin Xian. They were also submerged by large areas of rocks and boiling lava!
Cuckoo!
Beneath the suffocating deep-water harbor, the once wide waterway was now reduced to an extremely narrow passage by underwater sonar and scanning systems. As soon as Lin Xian entered carriage number 2, he looked out the porthole and saw a giant sea monster with black and white markings, tens of meters in diameter, hanging straight down into the abyss, seemingly without end, making his scalp tingle.

"This thing crawled in through the deep-water port's passageway, my god, it's a huge sea serpent!"

KIKI stared at the constantly flashing black and white stripes outside, her teeth itching with rage. Anyone who saw that would feel a chill run down their spine.

"It's still moving, trying to turn back and attack. Right now, those in the sea and on the island are probably all gathering here," Lin Xian said immediately.

KIKI said, "We're only 600 meters from the cliff passage into the deep sea. This thing is blocking the way, and I reckon the passage is already teeming with sea monsters waiting for us."

"Lin Xian, how much time do we have?" Seeing Lin Xian's condition, Chen Sixuan guessed that he was going to dive with the marker on, which meant that he must be in a very critical situation.

Lin Xian, breathing heavily, turned to look at Chen Sixuan, Monica, Brother Huo, and the others, and said in a deep voice...
"17 seconds."

Upon hearing this, everyone's pupils suddenly dilated!
Lin Xian didn't say a word. He grabbed the dangling handrail of the aisle and used the thrusters of his power armor to quickly reach carriage number 3. At this time, carriage number 3 had become a sea of ​​vines. A large number of green vines, like tentacles, firmly held onto the falling instruments, culture chambers and equipment to prevent them from falling.

Ding Junyi stood vertically on the ground, her expression calm. Countless vines extended from behind her, protecting Xiao Yuan, Miao Lu, and several other disaster plants, including Hell Black Chrysanthemum. The scene looked incredibly eerie.

"Team Leader Lin!" Xiao Yuan exclaimed in surprise when she saw Lin Xian enter.

Miao Lu gripped the vine and quickly said, "Almost there."

"How much?"

Lin Xian immediately looked at Ding Junyi, only to see that Ding Junyi's face was pale, her eyes were flashing wildly with supernatural light, and dozens of blood crystals had turned into a pile of sand, with only a few level-three blood crystals still connected.

Drop drop, drop drop.

Lin Xian's watch started beeping; darkness was about to fall.

But at this moment, darkness was no longer the biggest problem. He was marked with a level 4 mark, the detonator in the geothermal well was about to explode, and the Infinite was about to enter the deep-sea cliff. Lin Xian had to use the Silver Dragon Ten Thousand Mistakes at the moment of the explosion, when the black worms were destroyed, to make an instant disappearance in front of those deep-sea monsters, in order to have a chance to enter a state of silence in the blink of an eye.

Even if they succeed and escape the marked pursuers, it can only be considered as passing the first gate of hell.

With a whooshing sound, inside the Infinity train car, as the Infinity descended at a steep angle, many items fell into the car. Although there had been some prior preparations, many people were still somewhat flustered.

The people in carriage 2 were alright; KIKI used her telekinesis to stabilize everyone. In carriage 5, Da Lou used his body to block the equipment rack, while at the same time protecting Sun Yuzhen and her son Mo Xiaotian, who were hiding in a corner of the corridor. Shu Qin, Luo Yang, and Vanessa were protecting the ordinary team members from behind.

At this moment, the Infinite continued to dive deeper and deeper, 300 meters, 500 meters, 700 meters. As the water pressure changed, the internal pressure inside the cabin was also rapidly adjusted. The oxygen production system was in operation, and Viola monitored all the statuses of the train and reported to Lin Xian at any time.

15 seconds, 14 seconds...

At this moment, Ding Junyi, whose supernatural powers were surging wildly, slowly turned her head to look at Lin Xian and calmly spoke.

"It will bloom soon, but this time... it's not a bud."
