Four individuals were dressed entirely in ck gear, from their hats and robes to their shoes and gloves.


    This ck attire was quite distinct from regr ck fabric. While typical ck cloth is simply dark, their clothing appearedpletely devoid of light, resembling a ck hole.


    The reason for this striking appearance was ayer of ultra-ck material that has an exceptionally low light refractive index.


    This super-ck material is known scientifically as Vantack. Composed of carbon nanotubes, it has a light reflectivity of merely 0.035%, or 3.5 out of 10,000, making it the darkest material ever created by humans.


    The clothing was coated with this substance, rendering it almost invisible in dimly lit conditions. For ninjas adept at stealth, this advanced material was a dreame true, significantly enhancing their ability to remain undetected.<h3 style="background-color:DodgerBlue">


    At that moment, one of the men spoke up: “Brother, the guy hesitated for a moment before getting into the car. I used binocrs and it looked like he was staring at us. Do you think he noticed us?”


    The man he referred to as his senior replied coldly, “You’re just being ridiculous! The straight-line distance between us and him is over 800 meters, beyond the effective range of most sniper rifles. Plus, we’re about thirty meters higher than he is. How could he possibly spot us?”


    “Exactly!” sneered the man on the far left. “This kid is just a minor threat. He’s probably some Chinese master, but their internal power isn’t extraordinary. There’s no way he could find us from this distance.”


    The one who had asked earlier inquired, “Brother, since the Patriarch has instructed us not to act against him right now, what should we do?”


    The senior replied, “My second son and I will follow the convoy using powered paragliders. You two will drive, and stay in touch with me via radio.”


    The other three nodded in agreement.


    Shortly after, the brother and hispanion retrieved a pair of powered paragliders, also coated in the super-ck material, from the roof.<fnd53d> Discover more novels at FindN0vel</fnd53d>


    They started the paraglider engines, and as the dark machines were lifted by the wind, they took off from the roof, vanishing into the night.


    Meanwhile, Charlie, seated in the car, furrowed his brow.


    Before entering the vehicle, he had sensed that someone was lurking nearby.


    Having been fortunate enough to possess the “Apocalyptic Book,” he asionally received spiritual stones and reiki, which, along with his frequent consumption of Rejuvenation Pills, had enhanced not only his physical strength but also his perception far beyond that of an ordinary person.


    The four individuals positioned atop the distant building were not only well-concealed but also adept at controlling their breathing. Yet, they still failed to evade Charlie’s keen senses. He began to consider the implications.


    First, their presence in the shadows indicated they were likely up to no good, and there was a 99% chance they were there for him. Second, these individuals were skilled fighters, not just anyone. Lastly, their ability to hide their movements suggested a high level of expertise.


    Based on these observations, Charlie concluded that these four were likely the infamous ninjutsu masters from Japan,monly known as ninjas.


    Furthermore, their master was almost certainly the Takahashi family, whom he had just offended!
