Infinity: Kill your way through the movie world.

The open space outside the workshop was deathly silent.

A cool breeze blew by, stirring up dust and withered leaves on the ground, making a rustling sound.

John's spot was empty, except for his Colt 1911 pistol lying on the ground, with a few drops of dark red blood that had not yet completely congealed.

A faint, lingering stench of sulfur and a chilling, profound dark energy remained in the air.

"Daddy?!" Dean picked up his father's pistol and shouted anxiously into the surrounding darkness. His voice echoed in the empty factory area, but he received no response.

Sam quickly examined the ground, trying to find any signs of a struggle or dragging, but found no other clues besides a few drops of blood.

John Winchester seemed to have vanished into thin air.

“Lore!” Dean turned sharply to Wu Heng, his eyes filled with urgency and pleading. “Your butler… can he find my father, like he did at the sewage treatment plant last time?”

Wu Heng didn't speak, but simply nodded slightly.

The Grim Reaper's butler behind him stepped forward silently, his withered figure appearing even more eerie in the bleak twilight.

It slowly raised its hands, and a surge of gray energy rippled violently in its empty eye sockets, attempting to capture, sense, and lock onto the remaining traces of John Winchester's 'existence'.

Whether it's the breath of life, signs of death, or fluctuations of the soul, they can generally be detected.

However, this time, the situation is completely different.

The Grim Reaper's senses, like invisible tentacles, had just begun to spread out, attempting to trace the few drops of blood on the ground and John's lingering scent, when they suddenly crashed into an invisible, intangible, tough, and cold barrier.

This barrier, composed of pure and powerful dark energy, filled with the burning sensation of sulfur and blasphemous malice, not only forcibly blocked all possibilities of tracking, but even suddenly surged back, attempting to erode Death Butler himself.

Buzz--!

A silent energy collision erupted at a level imperceptible to ordinary people. The air around the Death Butler distorted slightly, its withered body swayed imperceptibly, and the gray aura in its eye sockets dimmed a bit.

He slowly withdrew his hand, turned to Wu Heng, and let out an extremely hoarse sound, like two rusty pieces of iron rubbing together:
"Master, the aura has been forcibly concealed and interrupted by a higher level of darkness. It cannot be tracked." It paused, seemingly trying to discern the essence of the remaining power, and finally confirmed, "It is the power of a demon!"

Wu Heng nodded slightly.

The Grim Reaper's tracking ability touches upon the essence of an individual's life. A demon capable of forcibly interrupting and completely concealing such a thing is no ordinary being.

“It must be it.” Wu Heng made a quick judgment, his voice calm. “The one who took your father away is the target you’ve been searching for, the Yellow-Eyed Demon.”

"Only power of its level can so cleanly and effectively interfere with the perception of 'death' itself."

"Damn it!" Sam and Dean exclaimed simultaneously, their eyes instantly filled with anger and even deeper worry.

The consequences of their father falling into the hands of their most powerful and ruthless enemy are unimaginable.

Now that they've lost Death's butler, their most powerful tracking tool, the Winchester brothers seem to have returned to their old, needle-in-a-haystack monster-hunting mode.

They were extremely anxious, but they could only force themselves to calm down and resort to all traditional methods.

Back at the hotel, the two brothers frantically contacted all the demon hunter friends they could reach, researching various rumors and records of demonic activities, trying to find any clues as to where the Yellow-Eyed Demon might be hiding.

During this time, in order not to overlook any potentially related clues, they went to handle two seemingly unrelated supernatural events based on information provided by other witchers:
One case involves a clown who appears in a small town amusement park, using his disguise to become invisible and murder children; the other involves a girl who was hit by a car and killed due to relationship problems, who then becomes a vengeful ghost seeking revenge.

The two resolved these troubles with great efficiency, hoping to find even the slightest bit of information related to the Yellow-Eyed Demon, or hoping that their father would, as always, leave behind a Witcher's distress signal somewhere that only they could understand.

However, no.

Nothing at all.

The Yellow-Eyed Demon and their father, John, seemed to have vanished from the world entirely.

The two brothers were tormented by immense pressure and anxiety.

Dean became more irritable and easily angered, while Sam became increasingly silent, often staring blankly at the computer screen, his eyes hiding emotions that others could not understand.

Two days later, Sam's phone suddenly received an encrypted message from an unknown source.

He opened the app and glanced at it. His face turned deathly pale instantly, and his fingers even trembled slightly. He then slammed his phone shut, glanced frantically at Dean, who was wiping his weapon, and Wu Heng, who was sitting quietly to the side, and stood up abruptly.

He glanced cautiously out the window again, as if he had seen something.

"I'm going out to buy some food." Sam's voice was a little hoarse. Without waiting for Dean's reply, he grabbed his coat and hurriedly left the motel room where he was temporarily staying.

Dean didn't pay much attention at first, but half an hour later, he realized that Sam had been gone for far too long, and an ominous premonition gradually gripped Dean's heart.

He dialed Sam's cell phone, but it went directly to voicemail.

"Something's not right!" Dean jumped up and paced restlessly around the room. "Sam is definitely hiding something from us!"

He looked at Wu Heng again, his eyes filled with worry, "Luo Er, what exactly did Sam do?"

Wu Heng snapped his fingers, and Death Butler traced back again.

Once again, it was blocked by the erupting dark barrier, but this time, during the backlash, a miniature transparent tentacle appeared in front of the Grim Reaper's butler, blocking the backlash for it.

At Dean's request, the two got into the car together, and Dean drove around the city looking for clues.

They then impersonated an FBI agent, reviewed nearby surveillance footage, and discovered that Sam had left with a blonde woman who appeared to be around 20 years old.

As she left, the woman seemed to sense something and glanced at the surveillance camera.

The video clearly shows that the woman's eyes were completely black.

"Damn it, it's that devil again!" Dean clenched his fists. "This must be related to Father, but where did he go?"

Two hours later, after a fruitless search, Dean, filled with anxiety, suddenly lost control of his hands, wildly swerving the steering wheel, causing the car to shake violently.

Wu Heng extended his left hand and easily took control of the steering wheel.

"Ugh--!" Dean suddenly let out a painful groan, clutching his head without warning, and collapsed to the ground, his body convulsing violently. (End of Chapter)
