Honestly, this telekinesis ability was truly useful. Without the remote control provided by telekinesis, Roy would have to be cautious in order to kill Zombies, which was far too dangerous.
After killing a Zombie, Roy cautiously entered an office building. The sound of him smashing the Zombie's skull just now wasn't quiet, and he didn't know if it would attract other Zombies.
Hiding in a concealed corner on the second floor, Roy used his telekinesis to control a steel pipe and strike the ground, making a sound. After a moment, sure enough, several Zombies were lured out.
Roy counted.
"3."
Moreover, judging from this, the Zombies here were indeed very sensitive to sound. It was unknown how their eyesight was. While testing the Zombies' senses, Roy controlled the steel pipe to successively smash the heads of the three Zombies.

"Phew—"
After this, Roy exhaled a long breath. It felt incredibly tiring, just as if he had personally swung the steel pipe to smash several Zombie heads.
"Stamina is also an issue. I hope that after telekinesis levels up, this aspect will also improve. Otherwise, it won't be usable for long in a single day."
Of course, him always using the steel bar was also a problem. If he could have a blade in his hand, he estimated it could save a lot of effort. But at this moment, there was no way to ask for so much; he could only use whatever he had.
Roy liked to mutter to himself when he was alone. This was a habit he had formed on the Blue Star because if one didn't open their mouth to speak often, they would gradually forget how to organize language, thereby affecting thinking and intelligence. To survive in such ruins, one must always be rational and clear-headed.
Furthermore, this was also a way to resolve loneliness.
After confirming there were no Zombies on the second floor, Roy began searching around. He unexpectedly found some bottled water and chocolate in the break room, as well as a fruit knife.
Considered as having a blade, Roy polished it slightly. Then, he fiercely ate several pieces of chocolate and also drank a bottle of water, not even caring if it was expired.
He had forgotten how long it had been since he tasted the flavor of chocolate products. The cloyingly sweet taste spread in his mouth; this moment was probably the happiest moment for Roy in several years.
After resting for about an hour, Roy recovered quite a bit of stamina. The window glass was already shattered. He looked through the window towards the sun in the sky.
"The sun is about to set. I must complete one upgrade mission before sunset; otherwise, the night is too dangerous."
In his current state, Roy had absolutely no mind to consider the main mission. The most important thing for him right now was to keep his life and survive. Exploring the truth of the world was something for later; after all, he still had five years.
His thin body stood up. Roy walked out of the tea room with the knife in hand. The look in his eyes was calm like water, without ripples, only the knife in his hand revealing a trace of murderous intent.
The sun gradually went west, until twilight gradually thickened.
Third floor.
A Zombie was wandering aimlessly. The sound of wind breaking arrived, and a fruit knife reflecting cold light shot forward, directly stabbing into the Zombie's head for a burst of mixing before being pulled out again.
Thud.
The Zombie fell to the ground.
The fruit knife flew back to Roy's side. At this moment, his expression was already extremely weary, but what was worth being happy about was that he had finally completed one upgrade mission.

[ Telekinesis · LV2! ]
In an instant, Roy's fatigue was completely swept away. The telekinesis inside his body rapidly expanded, and along with the expansion of telekinesis, Roy's thin body also became healthy and strong.
Roy could very intuitively sense that the strength of his telekinesis had received a very large degree of enhancement. If the strength of his telekinesis before was equivalent to his physical strength, then now it was different.
He looked at the steel pipe strapped to his waist. With a thought, the steel pipe flew into mid-air. Roy merely reached out and clenched his fist, and the hard steel pipe was directly crumpled into a ball.
After the upgrade, the strength of the telekinesis was large enough to make Roy extremely pleasantly surprised. By a rough estimate, his current effective control range was a thirty-meter radius, much larger than before.
Moreover, after the telekinesis upgrade and strengthening, Roy's stamina also clearly had some enhancement. This point was the same as he had thought before: stamina was positively correlated with the endurance and strength of telekinesis. Once one was enhanced, the other would also be enhanced.
"With telekinesis of this intensity, even without using a weapon, I should still be able to crush a Zombie's head from a distance. But it's still better to use a weapon; it will be more effortless. Moreover..."
Roy leaped up from the ground, and then unexpectedly jumped up directly and stepped upside down on the ceiling. Invisible telekinesis, like nails driven into the ceiling, firmly fixed his body.
"I can swing between buildings."
One night passed.
When the sky gradually brightened, Roy, after resting fully, ate two pieces of chocolate. Then, he walked up towards the higher floors with the knife in hand. The fruit knife, whose handle had been removed, had completely turned into a telekinetic throwing knife, polished to extreme sharpness.
"Roar!"
A Zombie opened its mouth to howl, and then its brain was twisted and shattered by the throwing knife entering its mouth. The remaining Zombies ran over following the noise. The throwing knife traced a lightning-fast trajectory, cutting them down like weeds.
[ Zombie Kill Count: 21 ]
Bang!
Bang!
Bang!
Several Zombies fell to the ground one after another. Roy, however, stood leisurely and contentedly in the office and pulled out a pair of scissors. He tried to control the scissors while distractedly controlling the throwing knife, but the result was that he basically couldn't do it.
"As expected, I still can't multitask. I have to go through training for it."
Just like that, Roy cleaned up floor by floor, until all the Zombies in the building were dealt with by him, and his stamina and spirit felt clearly fatigued.
[ Zombie Kill Count: 96 ]
Pity.
The number of Zombies in the building was much fewer than he had imagined. Until the Zombies on the top floor were cleaned up, Roy still couldn't complete the second upgrade mission.
Then he could only go to other places.
Roy had almost searched through all the tea rooms in the entire building and carried quite a bit of chocolate on him. There was no necessity to continue hiding in this building.
On the top floor, the wind howled. Roy looked down once, then jumped down directly. Telekinesis turned into grappling hooks and ropes, grabbing the outer wall of the building and swinging in the air.
On the twenty-third floor of a certain building, the window glass outside had long since been damaged. Borrowing the sunlight, it could be seen that quite a few Zombies were wandering inside this floor.
A Zombie wandered to the window, and then its head was decisively pierced through by a throwing knife. Roy swung over with a leap from mid-air, accurately landing inside the building.
Hearing the noise, the remaining Zombies were immediately alarmed.
"Roar!"
"Roar!"
Roy waved his hand, and the throwing knife traced astonishing cold gleams, killing all nearby Zombies like cutting grass. Black blood splattered into mid-air, and then Zombie after Zombie fell to the ground together.

With the completion of the second upgrade mission, Roy's telekinesis received an upgrade once again.
