"As expected, the mutant zombies are extremely difficult to deal with. Then, I can only ambush you all." Lin Fan looked down and saw a horde of zombies starting to move in the building.
Lin Fan ran up and down the stairs. If he stayed on top of the building and faced the mutant zombies alone, he could die from running out of resources. His eyes found the firearm lying on the floor.
"Has anyone used this gun?"
Lin Fan suddenly remembered the uniforms used by the zombies he killed.
"They're wearing Hunter, military, and civilian uniforms. Damn! What the hell is Shireen trying to do!" Lin Fan finally felt Shireen's horror.
"But, that goes against her cute demeanor. Could it be that someone's controlling her?"
Lin Fan still remembered when Shireen said that her job as a researcher. He asked, "Is this what she researched?"
Shireen became more and more mysterious in Lin Fan's heart.
"I don't have time to think about it. I've to get out soon."
Lin Fan made a firm decision. He takes the gun, but he doesn't find the bullet.
"Where's the bullet? Could it be Qi energy?"
Lin Fan tried to channel his Qi energy into the gun. But he didn't get any reaction. He found a blank in the gun's body.
Lin Fan looked around the floor and found green-colored crystals splattered there. He took it and attached it to the gun body. Then, he shot it in a random direction and a gunshot finally sounded.
"Is this an abandoned advanced weapon?" asked Lin Fan, the gun in his hand belonging to the advanced weapon category.
Lin Fan uses crystals for bullets. The bullets will not run out as long as the energy in the crystal is still there.
"Hmm, although for Qi practitioners, this thing isn't as efficient as using a sword or knife. However ... it's still a modern weapon. Well, I don't know ... during these 100 years, what weapons did the human race create to kill zombies?"
Lin Fan felt that the zombie apocalypse in the early years of its appearance must be creepy and anxious everywhere.
He was lucky and was able to jump over the early stages of the zombie apocalypse. But now, he doesn't know the evolution of zombies over the past 100 years.
100 years of the human race killing zombies, are they don't extinct? Why do they seem to appear infinite? Do they have a respawn system?
Impossible ideas and conjectures appeared in Lin Fan's mind. But, he soon returned to reality, due to the sound of the zombies getting closer.
"They're already here."
Collecting the energy crystals scattered on the floor, Lin Fan prepared to face the zombies. He looked around, but found nothing to hold on to.
"Aarrgghh!"
The screams of the zombies are getting closer, and the crisis is coming. Lin Fan immediately descended the stairs and looked down, aiming, shooting!
Pow! Pow! Pow!
One zombie disappeared when the shot hit his head. However, Lin Fan saw that something had fallen from him. He didn't have time to observe the thing he knew.
This gun was capable of eliminating zombies. He wondered, why a weapon as good as this was abandoned?
Lin Fan did not sink into the euphoria of victory. He kept shooting towards the head of the mutant zombie.
Unfortunately, as if learning from mistakes, the mutant zombie started running up the stairs faster. Under the waves of zombies, Lin Fan's shots became frequently missed and the energy within the crystal was rapidly depleted.
"As I expected, compared to swords and knives, this thing's unreliable at a critical time!"
Putting the gun into the storage ring, Lin Fan immediately took out the one remaining sword from there and began to dive into the zombie wave.
"I only have 10 healing bottles. So, just avoid the bites."
Like a tornado, Lin Fan swept away waves of zombies.
A Qi-coated sword slash split their heads, making Lin Fan feel the blood baptism of the zombies.
However, the zombies he killed did not disappear like being shot by a gun. The body is still there. After finishing the first wave, Lin Fan immediately ran downstairs and wanted to close the door immediately.
Along the way, Lin Fan killed many zombies. He was lucky to meet them in a tight space. Avoiding the risk of being bitten from all directions, Lin Fan only needed to focus on slashing at the enemy in front of him.
But currently, a snapping sound rang out from his sword.
Clang!
Seeing his sword broken, Lin Fan only knitted his brows.
"I didn't expect this thing to be so fragile. There was no other choice."
Lin Fan took out a dragon knife from the system bag.
"In the end, I can only rely on durable system items."
The third wave of the mutant zombie massacre has begun.
Lin Fan didn't know if it was his feeling, he felt that his strength and reflexes were increasing.
With the mutant zombie battle experience, he bought from the Immortal Store, the mutant zombie before him was like soft tofu. In comparison, Lin Fan was like a mutant zombie with both intelligence and weapons, while his enemies were just ordinary mutant zombies.
The massacre is not impossible.
"Using the dragon blade can save a lot of Qi energy."
After slaughtering the third wave of zombies, Lin Fan looked at the horde of zombies in front of him as if they were endless. He could only give up and save some energy.
He saw the red switch on the wall and pressed it. With that, 10 iron barriers between the two appeared. Finally, Lin Fan was separated from the next wave of zombie hordes.
He did not rest and immediately returned to the roof. If he was late, the zombies on the roof would surround him as well.
One whole day, Lin Fan spent his time just killing zombies, and his energy was running out.
***
Lin Fan lay on the roof and looked at the dark sky. In his hands, he held a green crystal similar to a spirit stone.
"This energy crystal came from a mutant zombie."
Lin Fan realized many things today. The mutant zombie, who has a crystal on his forehead, will be resurrected into an ordinary zombie once the crystal is taken.
The most efficient way to kill zombies is to obliterate their bodies.
"And, this gun's supposed to be a vestige of lost knowledge. But, I still don't know what Shireen is trying to do?"
