Daoist Singularity had fallen, but the command he left in the underlying network of the Underworld was like a delayed time bomb, finally detonating in the depths of the data sea.

  [Execute Command: Modify Variable "Invincible".]

  In normal game or program logic, "Invincible" is usually a Boolean Value.

  Only two states: True (Yes) or False (No).

  As long as this switch is On, no matter how many billions of damage you deal, the system judges it as 0.

  This was why Slayer's previous attacks were all ineffective. Because the Ancestor's switch was soldered dead on True.

  But the strike Singularity delivered by burning his divine soul didn't directly turn off this switch (because the Ancestor's privileges were still resisting).

  Singularity did something more extreme.

  He used Administrator privileges to forcibly modify the "Variable Type."

  He changed Invincible (Boolean) to HP (Integer).

  In other words, he forcibly changed the "Invincible Switch" into a "Health Value."

  [Modification Complete.]

  [Invincible = True] -> [HP = Max_Integer]

  In computing, Max_Integer is usually an astronomical number.

  This meant the Ancestor was no longer "Unkillable."

  He became a super tank with "Hundreds of Billions of HP."

  Although the health bar was despairingly thick, his status had changed to—Damageable.

  ...

  Real World. Blood Sea.

  Stolen from its original source, this story is not meant to be on Amazon; report any sightings.

  Slayer hovered in the Blood Sea, which was flowing backward due to gravity reversal.

  Although that BFG shot just now shattered the Ancestor's outer shield, the Ancestor's true body remained unharmed under the protection of that golden light.

  The Ancestor, though beleaguered by the environment, remained arrogant: "Even if the heavens fall and the earth cracks, I am an immortal body! What can you, a mere mortal, do?"

  Just then.

  Slayer's tactical visor suddenly jumped.

  The last data packet left by Singularity before fainting finished loading.

  The red label [Invincible] representing the Ancestor's status in his vision flickered and disappeared.

  Replacing it was a long, dark red, massive health bar stretching across the entire field of view.

  The number on the health bar was a dizzying string of "999999999...".

  Slayer paused.

  He looked at the health bar.

  Then at the Ancestor who was laughing maniacally.

  For an ordinary person, seeing such a ridiculous health bar might induce despair. Because it meant fighting for tens of thousands of years.

  But in Slayer's eyes.

  This wasn't called despair.

  This was called a "Progress Bar."

  As long as there is a health bar, it can be killed.

  As long as it bleeds, it's just a matter of time.

  Slayer's mouth (if visible) probably grinned to his ears.

  It was the pure ecstasy of a hunter finally seeing the prey expose its neck.

  Click-clack.

  He loaded fresh shells into his double-barreled shotgun.

  Then, he made a move.

  He raised his hand and fired a casual shot at the Ancestor's seemingly still invincible golden body.

  BANG!

  No earth-shattering special effects. Just a standard shotgun blast.

  The pellets hit the Ancestor's face.

  This time, they weren't bounced off.

  Splurt.

  A tiny flower of blood bloomed on the Ancestor's cheek. Although relative to his massive size, this wasn't even a mosquito bite.

  But in Slayer's vision, that massive health bar... extremely faintly, but definitely... dipped a sliver.

  [HP: -1]

  The Ancestor's laughter choked in his throat instantly.

  He touched his face.

  Wet.

  Painful.

  "Blood...?" The Ancestor looked at the drop of golden divine blood on his fingertip, his pupils quaking. "I... bled? How is this possible?!"

  "Logic vs Value."

  Invincibility is a logic, an absolute rejection.

  But Health Points are a value, a consumable resource.

  Slayer didn't care how big your number was.

  He only knew that now, The Game Was On.

  Hum—!

  Slayer drew all the weapons on his back.

  Chainsaw, Rocket Launcher, Heavy Cannon, BFG...

  It was as if a virtual armory projection appeared behind him.

  Since you have hundreds of billions of HP.

  Then I'll fill it with hundreds of billions of bullets.

  Slayer activated "Infinite Ammo Mode" (thanks to the logistics pipeline established earlier).

  He was like an excited drummer facing a massive drum.

  Dum-dum-dum-dum-dum-dum!

  The first wave of offense, Started.

  "Next chapter, The Health Bar Lights Up. Slayer says: As long as the health bar lights up, I'll kill even a god for you to see."
