Meanwhile, two dark, silent paragliders soared swiftly at an altitude of two hundred meters.


    These paragliders operate on lithium batteries that power electric engines, eliminating the noise typically associated with fuel engines.<fna078> Newest update provided by Find?Novel</fna078>


    Furthermore, the design of the fan des on the paragliders minimizes air noise even during high-speed flight.


    The Japanese ninjas have consistently pursued the development of equipment to enhance their abilities.


    In earlier times, ninjas not only dedicated themselves to mastering ninjutsu but also delved into chemistry to craft a range of unique tools.<h3 style="background-color:DodgerBlue">


    Television often depicts ancient ninjas dropping a ball that instantly produces smoke. As the smoke dissipates, so do the ninjas themselves. This isn’t merely fiction; it has roots in historical reality.


    The round balls used by these ancient ninjas were actually a blend of smoke bombs and sh bombs created using traditional methods.


    When detonated, the intense light temporarily blinds opponents, while the smoke provides excellent cover for a swift escape. By the time the adversary regains their vision and the smoke clears, the ninja has long vanished.


    However, this may not capture the full truth.


    Ninjas are akin to chameleons, adept at blending into their surroundings and evading detection.


    When their targets believe they have escaped, ninjas might be hiding in the beams of a house, lurking behind their target, or even submerged in water, using thin bamboo strips to breathe.


    Modern ninjas have embraced technological advancements, enhancing their stealth capabilities.


    For instance, the ultra-ck materials they use, like those on their paragliders, represent their contemporary techniques.


    At this moment, the two individuals on the paraglidermunicated through a wireless inte. One of them remarked, “Brother, should we maintain a bit more distance? We don’t want them to spot us.”


    “Not a chance,” the senior replied confidently. “We’re currently two hundred meters high, with a straight-line distance of nearly one kilometer from them. At this range, they can’t hear us or see any clues. Even if someone directly below looks up, they won’t spot us!”


    The lead ninja believed he had achieved the perfect concealment, but, unbeknownst to him, Charlie had already noticed the two of them.


    Upon realizing he was being watched, Charlie couldn’t help but smirk. It seemed these ninjas were determined to pursue him, but he wondered when they would make their move. Rather than feeling anxious, he actually found himself looking forward to it.


    As a child, Charlie had enjoyed various ninja-themed movies, TV shows, and cartoons, which sparked his curiosity about the ninja profession. He was eager to confront Japanese ninjas directly to gauge the prowess that Japan had boasted for centuries.


    Thus, he resolved to stick to his original ns while keeping a close watch on the movements of the four ninjas to discern their intentions.


    Twenty minutester, the convoy halted outside Ichiro Kobayashi’s residence. Charlie and the others entered the building and ascended to the top floor. At that moment, the two ninjas on powered paragliders hovered in the night sky above the building while the other two descended to the ground.
