The three of them walked cautiously on the stairs, trying not to make a sound, which also made the already empty and silent corridor extremely depressing.

"Roar!"

When the three of them tiptoed to the staircase on the fourth floor, they were startled by a sudden zombie howl.

The two peasants were very calm and capable, and they hurriedly protected Zhang Xiaoming in the middle and made a defensive posture.

Zhang Xiaoming, who was already nervous, was so frightened by this voice that his little heart jumped up, and his legs became weak.

However, fortunately, he was quick and hurriedly helped Farmer No. 1 who was blocking in front of him, so he escaped and did not fall downstairs.

Gently wiping the cold sweat from his forehead and protecting the pan in front of him, he nervously peeked towards the place where the sound came from.

But to his great surprise, he didn't see any zombies attacking them.

So, what happened to the zombie that suddenly howled just now?

Although he was extremely surprised in his heart, he didn't have the heart to delve into it, and the first task now was to go to the first floor, so there was no need to delay here.

He motioned for Farmer No. 1 to move on, leaving things alone for now.

Farmer No. 1 was ordered to continue to cautiously open the way in front, and Farmer No. 2 was at the end careful to guard against possible sudden danger behind him.

"Boom!"

They had barely reached the corner of the staircase when the sound of a bowstring snapping suddenly sounded.

With a "boom", the sharp arrow turned into an afterimage and roared out from the arrow tower dragged in front of Farmer No. 1.

The three of them hurriedly looked in the direction where the arrow was shot, and saw that a white-haired zombie had been nailed to death in the corner by the arrow.

It seems that this sad zombie should have been alarmed and attracted by the howl just now.

[System]: "Ding! Kill a normal zombie in the arrow tower and get a point reward. ”

When he came to the old man's zombie, Zhang Xiaoming muttered a few words of prayer in a low voice before silently choosing to sacrifice.

In this way, a little bit of energy can be easily obtained.

[System]: "Ding! Sacrifice a normal zombie corpse to gain one energy point. ”

Listening to the system prompts, Zhang Xiaoming suddenly thought that he was going to destroy a large number of zombies later, if he killed every one with a prompt, then he would not be killed by a series of endless system prompts.

So, he tried to whisper again, "Turn off the kill prompt, turn off the sacrifice prompt." ”

[System]: "Ding! The function is disabled. ”

It really works!

He was satisfied with the user-friendliness of the system's functionality.

"Boom!"

Before he could finish his feelings, the sound of the bowstring bounced suddenly sounded again.

Before they could react, the sharp arrow had turned into an afterimage, roaring out from the arrow tower dragged in front of Farmer No. 1, killing the zombies that had just emerged.

Once again, they easily recorded one point and one energy point, and they had already arrived at the entrance of the corridor on the third floor.

Without stopping, he continued to walk cautiously downstairs.

In the next few floors of the corridor, they were still in danger, and before they saw the zombies, the zombies had been easily killed by the arrow tower.

When they came to the lobby on the first floor and saw the door of the unit building closed intact, they felt a lot more relaxed.

But for the sake of safety, they still came to the gate and carefully inspected the gate to make sure that it was intact and locked.

However, when he was about to leave the underground parking lot, Zhang Xiaoming gritted his teeth and bought a wooden fence in the card store and placed it in front of the gate of the unit building.

In this way, if the door of the unit building is breached, his wooden fence will be attacked, and he will be able to receive a warning in advance.

Although it is a bit painful to consume points, he feels that he can be more assured by making more preparations, and sooner or later he will have to buy a wooden fence to increase the unlocking degree, which is not a waste.

When he came to the stairwell on the basement floor, he found that the doors on both sides of the corridor actually had electronic locks, and they were still locked, and he was finally completely relieved.

Everything is ready, now all you have to do is go to the second floor, find a place to attack, and start planning.

Arrived on the second floor, walked around quickly, found that the doors of two houses were open, and when I entered, I found that there was no danger, and the valuable things in the house were also taken away, and it seemed that the two residents were evacuated with the federal government.

After comparing the two houses, they chose a living room with a good location and a wide view as the venue for the battle.

Close the door, drag out the tent, prepare the battle materials, and then collect the floor-to-ceiling windows and window frames, and drag the arrow tower to place it.

When everything was ready, the three of them frantically tapped the shields and pans in their hands, making a loud noise.

"Roar......

"Roar......

Suddenly, the zombies wandering near the residential building were all alarmed, and they began to roar and continue to converge towards Zhang Xiaoming and them.

"Boom!"

As the zombies approached, the sound of bowstring ejection also sounded.

With a "boom", the sharp arrow turned into an afterimage and roared out of the arrow tower.

With a "poof", the sharp arrow shot through the back of the head of a zombie, and then through the chest of the zombie behind it, before finally exploding into sawdust in the chest cavity of the third zombie.

Since then, every twenty seconds, at least one zombie has been killed on the spot by a sharp arrow, and this arrow tower can be regarded as having turned on the continuous shooting mode.

Watching one zombie after another fall to the ground, Zhang Xiaoming was both nervous and excited, these are all points and energy points.

Not long after, dozens of zombies had gathered downstairs, and they were climbing frantically, wanting to eat the three of them who were standing upstairs watching the play.

But the floor-to-ceiling windows downstairs were so slippery that they couldn't climb up at all.

Seeing that a lot of zombies had gathered, Zhang Xiaoming did not hesitate, directly took out a glass bottle filled with gasoline and plugged with rags, lit it with a lighter and smashed it towards the zombie group.

The glass bottle crossed a graceful arc, and with a "bang", it smashed on the head of a zombie.

"Boom!"

The glass bottle exploded like a grenade.

In an instant, the gasoline in the bottle was like a rain of fire, splashing in all directions, instantly igniting the zombies that hit him on the head, as well as several zombies nearby.

"Roar! Roar! ”

Several burning zombies howled and tried to escape.

But because they were surrounded by a large crowd of zombies, they couldn't move at all.

Since then, they have had to be burned to death in the zombie horde, wailing and burning.

Seeing the power of the homemade "incendiary bomb", Farmer No. 1 and Farmer No. 2 also hurriedly followed suit, began to ignite the gasoline bottle, and smashed it into the zombie group gathered downstairs.

In a short time, piles of zombies downstairs were ignited one after another.
