The wind screamed in his ears, threatening to tear his eardrums apart.

  Slayer was in a state of Free Fall.

  Beneath his feet, the massive vertical tunnel blasted open by the BFG was like a bottomless abyss. But he wasn't falling into darkness; he was plunging through world after bizarre world.

  Third Layer: Iron Tree Hell.

  This layer was a forest of steel trees bristling with sharp blades.

  Slayer's descent speed was immense, yet he adjusted his posture in mid-air. His tactical visor instantly locked onto a "Undead Marksman" hanging from a branch below, attempting to snipe him with a bow and arrow.

  Slow-Motion Perspective engaged (Chrono Strike rune passive).

  Slayer rolled in the air, head down. The double-barreled shotgun in his hand aimed steadily.

  BANG!

  The shotgun spewed a tongue of fire. The Undead Marksman's head exploded instantly. Before the green blood could even splash onto Slayer, he had already punched through this layer.

  Whoosh—!

  The wind noise intensified.

  Fourth Layer: Mirror Hell.

  Mirrors were everywhere, shattering and refracting countless reflections of Slayer.

  A massive "Mirror Demon" tried to extend a claw from a mirror to intercept him.

  Slayer didn't fire. Utilizing the kinetic energy of his fall, he violently extended the Doomblade on his left arm.

  Zzzzt—!

  In the instant he skimmed past the mirror, the arm blade was like a silver bolt of lightning, slicing directly through the mirror surface and the throat of the demon hiding within.

  The mirror shattered, and the demon's scream was left far behind.

  Fifth Layer: Steamer Hell.

  Scalding steam rushed into his face, instantly reducing visibility to zero.

  But this couldn't stop Slayer.

  Thermal Imaging engaged.

  In the white mist, dozens of red heat signatures (demons) were gathered around the hole—survivors or onlookers of the BFG blast.

  Slayer pulled a Frag Grenade in mid-air, pulled the pin, and dropped it.

  BOOM!

  The grenade exploded in the steam, firelight instantly swallowing that layer. Slayer passed through the fireball. His Praetor Suit glowed red hot, but he remained unharmed.

  Sixth Layer... Seventh Layer... Eighth Layer...

  Every layer was just a fleeting moment.

  The red glow of copper pillars, the cold glint of knife mountains, the chill of icebergs... these Underworld punishments, normally terrifying enough to make ghosts tremble, were now mere background scenery for Slayer's descent.

  He was like a precision-guided Bunker Buster.

  Every time he passed a layer, he fired a shot or swung a blade.

  No wasted movement, no hesitation.

  Bang! (Another demon headshot.)

  Slice! (Another demon bisected.)

  Fifty meters above him.

  Daoist Singularity had slapped a "Super Slow-Fall Talisman" on himself and was drifting down like a leaf battered by the wind.

  "Aaaaaahhhhh—!"

  Singularity's screams echoed in the deep shaft.

  He watched the green figure below, witnessing the most insane aerial ballet.

  "Too fast! Slow down! The structural integrity down there is unstable!"

  While screaming, Singularity frantically drew runes in the air with his multi-functional stylus, trying to reinforce the walls of this violently punched hole to prevent collapse.

  "Reinforce! Harden! Anti-Collapse! My god, I'm doing the cleanup for his demolition project!"

  Finally.

  As Slayer punched through the dust cloud of the Seventeenth Layer (Stone Mill Hell).

  A dark red glow appeared below.

  That wasn't firelight. That was the light of blood.

  Eighteenth Layer: Saw Hell.

  This was the terminus of this "Journey to the Center of the Earth."

  Slayer adjusted his body in mid-air, feet together, knees slightly bent, preparing for impact.

  Impact Compensation System charged.

  KA-BOOM!!!

  An earth-shattering noise rang out.

  Slayer hit the floor of the Eighteenth Layer like a meteorite.

  A massive shockwave spread out from him, blowing away and twisting the saw torture devices within dozens of meters.

  The dust settled.

  Slayer slowly stood up straight.

  The floor beneath his feet had cracked into a spiderweb pattern, yet he didn't even sway.

  He looked up and scanned his surroundings.

  This was the bottom of Hell. The air was filled with a suffocating oppression.

  Not far away, a group of high-level Demon Lords, holding saws and in the middle of sawing people, stared dumbfounded at this "uninvited guest" who fell from the sky.

  They couldn't react.

  They had just heard rumors of someone causing trouble on the Second Layer a second ago... how did he Arrive already?

  Click-clack. Slayer loaded fresh ammo into his shotgun.

  "Freefall Clearing."

  He was done. It took only 30 seconds to travel a path that took others hundreds of years.

  At this moment, a screaming sound approached from above.

  "Aaaah... help... can't stop..."

  Splat.

  Although Singularity had the Slow-Fall Talisman, he still landed awkwardly in a pile of rubble next to Slayer, eating dirt.

  He crawled up, adjusted his crooked Daoist crown, and looked up at the bottomless hole above.

  "Big Hero..." Singularity spat out a mouthful of dirt and gave a thumbs up. "You didn't take an elevator... you are a Human Pile Driver."

  Slayer's gaze was already locked onto the Gate of the Blood Sea.

  But Singularity hadn't recovered yet.

  He lay on the ground, rubbing his sore waist, looking up at the super-hole that vertically penetrated eighteen layers of Hell.

  The hole was as straight as if calibrated by a laser. The cut on every layer was smooth, and one could even see stray rocks and demon limbs falling from the upper layers.

  Singularity took out his tablet and saw the data bar titled "Underworld Structural Integrity" had dropped to a red 20%.

  "Oh my ancestors..." Singularity wanted to cry. "You had your fun, but this is a severe illegal construction! If Kshitigarbha Bodhisattva sees this, he'll nag me to death!"

  He pointed at the hole and complained to Slayer's back:

  "You call this going downstairs? You basically gave the Underworld a 'Rectal Passage'! This is too open!"

  Slayer didn't look back; his shoulders just shrugged slightly, perhaps reloading, or perhaps expressing disdain for the metaphor.

  Singularity sighed, resignedly climbing up to paste "Beware of Falling Rocks" talismans around the hole.

  Looking at the hole, a brilliant (and suicidal) idea suddenly popped into his head.

  "But... since the hole is open, could we maybe install a... Rapid Transit System?"

  Singularity's eyes lit up.

  "Next chapter, Spatial Collapse Crisis. It looks like the floor slabs can't hold on much longer. Need to patch it up fast—or just turn it into a vacuum tube?"
