As for the proficiency in firearms, it didn't bring much enhancement to Derick's physical abilities, but its effectiveness was not weak. After all, considering the current situation with zombies, firearms still played a significant role in the early stages.
Derick's physical condition hadn't reached the point where he could withstand bullets, but he had confidence that no one could shoot him within 10 steps. This was the power brought by being a master of Eight Extremities Fist.
There were many uses for the system's enhancement abilities, but Derick didn't have time to examine them one by one.
Although the Apocalypse King System was meant to assist him in establishing a dominant force in the world, for Derick, his top priority was to rescue his sister trapped at the airport before considering other matters.
Coincidentally, three zombies appeared nearby. Derick decided to warm up by grabbing the shovel in his hand. He dodged, parried, and struck, feeling incredibly agile.
The doubled physical abilities not only increased his attacking power but also provided a significant boost in strength. He was faster than before, and these three zombies couldn't even touch the hem of Derick's clothes as he skillfully avoided their attacks.
With just a swing of the shovel, he decapitated all three zombies in less than a dozen seconds.
Derick hardly felt any effort in the fight and remained energetic. This was the effect of his enhanced physical abilities, enabling him to engage in high-intensity, sustained combat.
"Nice," Derick exclaimed, excitedly clenching his fist. With this, the possibility of rescuing his sister greatly increased. More importantly, this Apocalypse King System was enough to make him live better than anyone else in this apocalypse.
Closing the screen in front of him, Derick continued forward with excitement. He encountered a lone small zombie and killed it.
[Killed a level 1 zombie, obtained 1 point, current score: 11]...
[Killed a level 1 zombie, obtained 1 point, current score: 15]
Passing through two streets, Derick killed a dozen zombies in total. Each time he felt the prompt in his mind, it filled him with extreme excitement. Zombies represented points, and points represented strength. Now, he could easily handle a dozen zombies on his own.
Unless facing a large horde, Derick could slowly wear them down. After killing a dozen zombies, the shovel in his hand became bent and the blade started to curl. Although the quality of the shovel was good, it couldn't withstand Derick's forceful use.
"Sigh, there isn't even a place to find weapons on the streets," Derick looked around the surrounding streets helplessly. The shovel he had been using earlier was already broken and discarded. He was worried about not having any weapons to use.
Beep beep beep. He absentmindedly dialed his sister's number again, not expecting much, but to his surprise, she answered quickly this time.
"Hey, sis..." Derick excitedly held the phone. "Little brother..." Angelica spoke at the same time.
"Sis, where are you now? Are you okay? And be careful of those zombies~" Derick's eyes teared up with excitement. Hearing his sister's voice again, he had genuinely been worried. Even if he made it to the airport, he feared that his sister might have already perished.
"I'm fine. I'm currently in the third-floor lobby of the airport. It's a cafeteria with food and water. The elevators going up and down are blocked, so it's relatively safe for now. How are things on your side?" Angelica's voice sounded somewhat joyful.
"I'm fine, sis. You stay there. I'm coming to rescue you now. Wait for me..." Hearing that his sister was safe, Derick felt a heavy burden lift from his heart. It had been three hours since the apocalypse began, and he had just managed to reach his sister on the phone, despite being halfway to the airport.
"No, don't come here. It's dangerous with zombies all over the streets. Please don't come," Angelica instantly became nervous upon hearing Derick's words, fearing that something might happen to her brother.
"It's okay, sis. I'm strong now, and I have a gun in my hand," Derick reassured her as he continued walking, speaking into the phone.
"I'm begging you, sis. I won't listen to you this time. If I don't come, I'll definitely regret it," Derick's words were firm.
"Sis, rest assured. I'm already halfway there. I will definitely rescue you. Just wait for me," Derick clenched his fist and then hung up the phone.
Angelica listened to the busy tone on the other end of the phone, staring blankly, unsure of what to say.
Although she had a very close relationship with her brother and had relied on each other while growing up, she knew that once Derick had made up his mind, it would be impossible to dissuade him.
She pursed her lips and decided not to sit idly by. She had to at least help her brother by solving some problems for him.
On the other side, Derick took a few bites of bread and discarded the plastic bottle of mineral water in his hand. He left the room and found himself 3 kilometers away from the airport.
This stretch of road wasn't too far, and if nothing unexpected happened, he would arrive in a little over an hour. Hopefully, no problems would arise.
Smashing open a fire hydrant on the street, Derick retrieved a fire axe from inside. He swung it around, testing its weight, which seemed decent. It should have decent power, and it felt good in his hand—a good weapon for killing zombies.
Using 20 points, he casually enhanced the fire axe in his hand. The blade became sharper, emitting a black gleam on the surface. The weight of the entire axe increased, and the other end transformed into a hammer, turning the fire axe into a hammer-axe.
Derick knocked down a zombie, a satisfied smile forming on his lips. The weapon enhanced with the system was indeed effective. And this was just one enhancement; he wondered what it would be like after a few more.
As he skillfully lifted the axe, a sudden scream came from behind. The high-pitched scream almost made Derick curse out loud—it was too loud, and nearby zombies would surely hear it.
Although Derick could easily deal with these zombies, it didn't mean he could recklessly overpower them. Despite having twice the physical stamina, he still had limits.
Moreover, his body was not yet immune to the infection. If he were caught, even if he didn't get infected, he would be severely injured.
And encountering a group of zombies would be even more terrifying. He couldn't afford to provoke a horde. He had to be cautious, as he couldn't protect himself fully from attacks from all directions. He didn't want to become a joke right after acquiring the system.
