Finally, after regaining his invisibility power, Jack went early to a bar where a group of losers often hung out all night, and the best part was that they usually left their bikes outside. Jack entered the bar confidently, causing confusion among the people there, and quickly struck one of them with his table, knocking him unconscious. His companions got up with looks of disbelief and curses, but they all ended up being violently beaten except for one person whom Jack intentionally avoided touching.

With all his companions lying helpless on the floor, the terrified man looked at Jack and stammered in fear, "Wh-why...? We didn't do anything to you... Please, leave us alone, I'll give you anything-"

Jack interrupted him with a slap to the face and ordered him in a cold voice to bring his bike to him. The man quickly went and brought his motorcycle, trembling with fear.

Jack smiled at him and raised his hand as if he was going to slap him again, causing the man to close his eyes in fear. Instead, Jack gently patted his face and kissed his bald head. "Wha... what... what is this?"

Jack swiftly took the motorcycle and set off toward the coordinates displayed by the system, an excited smile on his face.

The place was in the isolated and gloomy County E, which was perfect for building a secret base. As Jack approached, he found himself looking at an abandoned factory surrounded by a tall fence, and there were no signs of life nearby. He carefully observed his surroundings and circled the fence but found no surveillance cameras, guards, or even an entrance. This made him wonder if the people inside never left under any circumstances.

He looked at the warning sign that the fence was electrified and decided to touch it, confirming that it was indeed electrified enough to burn his hand.

"Wow, Jack, what were you expecting? That the fence and the factory were just a hologram hiding the real facility? Maybe in other worlds, but not this one. Now you have to figure out a way to get in."

Jack looked down and thought for a moment, then began to dig, but he found that the fence was deeply rooted, so he abandoned the idea. The absence of trees in this area made the idea of flying over the tall fence nearly impossible, but Jack moved a bit, jumped in place a few times, and did some warm-up exercises for his legs. He then took a few steps back, ran at full speed, used his momentum to press his feet against the fence, and jumped extremely high. He then bent his body at a sharp angle to lift himself a few centimeters above the fence before awkwardly falling on the other side.

"I need to improve my balance next time," Jack said as he cautiously advanced toward the factory and reached the front door. He looked at it for a while and tried to open it, but it was securely locked. Jack stepped back a little and tried to find any windows. After some time, he finally found one that was broken and could be entered through.

The problem was that it was at a considerable height, but that wasn't an issue for Jack. He started by making a hole in the factory wall with his hand and began to climb. The wall was not thin but thick and tough, yet Jack's fingers had no trouble making a hole and climbing through it.

When Jack reached the window, he widened the gap just enough for his body to fit without causing much noise. He then put his head in first to observe the situation inside, finding it quiet and motionless like the outside. Without wasting time, he decided to jump inside.

Despite his legs being stronger and sturdier, they still suffered a break when he jumped. Jack waited for a moment to recover before continuing his exploration. When he found nothing, he pondered, "System, is there an entrance for me here, or not? Please tell me quickly."

‹Yes... the way for you to enter is through a gap in the sixth tile to your right.›

Jack looked to his right and moved six tiles before touching the sixth one. He tried to move it a bit and found that it was indeed movable. With some effort, he managed to remove it.

After removing the tile, there was a dark and unclear hole of undetermined depth. Jack thought for a moment, "System, do I have to fall into this hole?"

‹Yes.›

"Hmm, good enough for me."

With that, Jack first inserted his legs, then slowly his upper body into the hole. The hole was small but still wide enough for Jack's body to fall into uncontrollably. So, he decided to use his back and front legs, with his hands on the sides, to create friction and control his falling speed. This action caused Jack's skin to be scraped, then healed by the regenerative power of his body, and then scraped again and again for an extended period, to the point that Jack could no longer bear the amount of blood and dirt on his body.

He started alternating between letting his body fall freely and gripping the walls of the hole, making the situation even worse. However, before he repeated this action for the tenth time, he noticed some light coming from below, indicating that he was getting closer!

Due to extreme boredom, Jack decided to just let go of his blood and sweat-soaked body to fall faster and faster without attempting to stop this time. As a result, he fell at a tremendous speed, and only when he noticed that the light was very close, he opened his body wide.

His back, arms, legs—every part of his body—were rubbing against the walls of the hole in a bloody and painful manner, even for Jack. His body was peeling off at a faster rate than it could regenerate, causing the muscles to grind against the walls, intensifying the pain, and causing significant damage. But in the end, Jack managed to gradually reduce his speed until he finally reached the light and fell out of the hole onto a white surface. Blood was splattered everywhere, with the smell of burning flesh. Even his previously used head had its beautiful black hair falling and burning, but that didn't matter because, as Jack slowly opened his eyes due to the intense brightness, he found himself in a small white room with no windows, only one door, and a small opening beneath it.

He looked around and knew he was underground, but he didn't expect it to be like this. However, his train of thought was interrupted by a sharp scream coming from behind the walls of the room.
