This system is a little annoying, Cao Fei closed the system page after reading these nagging words, and did not continue to read in the store. Pen & Fun & Pavilion www.biquge.info

In fact, as long as it is human, everyone has curiosity, and Cao Fei is no exception, he also wants to know how this iron spine spear has evolved and upgraded.

It's just such a shabby-looking thing, where can evolution go? Where can I upgrade to? What's going on? Is it carved on it?

But...... He knew in his heart that now was not the time to study these things.

Whether it's evolution or upgrading, it's something that can only be considered later, as the so-called matter has priorities, the most important thing now is to make sure that you can continue to live, either kill those zombies outside the door one by one, or find a way to escape from the office, and shake the iron spine spear in his hand, a little heavy, but it's still handy, okay...... Try it first and see if it works, and we'll talk about the rest later.

Squeak ...... Squeak ......

The zombies were still scratching the door, one after another, because there was not just one zombie outside at this time, but three zombies scratching together, and the sound was chaotic, which really made Cao Fei feel irritable.

"It's a blessing or a curse, it's a disaster that can't be avoided, come on, if you can pee out, you can look at it."

Cao Fei spat at in the palm of his hand, went over to grab the doorknob, and then pushed it outward.

He's ready to go out and fight the zombies!

The door, just like that, opened, very suddenly.

Immediately after, there was a popping sound outside.

was hit by Cao Fei opening the door, and the three zombies were all knocked to the ground.

Cao Fei was stunned: "Oh, how can this be?" ”

He looked down at his hand, a little incredulous, he didn't expect that he would have such a great power when he pushed the door, and he could knock down three zombies at once.

I remember the first time I had a zombie at home...... That is, when Professor Park Zhenglong's zombie was fighting, Cao Fei also used this trick.

Suddenly the door opened, and the door panel of the security door hit the zombie's face.

But the effect was not good, only knocked the zombie back two steps, that's all, and then after less than two seconds, the zombie pounced again.

That time, it was just an ordinary zombie, and the door was an anti-theft door, very strong and heavy.

This time, however, there were three zombies, including a more advanced zombie, but the door was an ordinary wooden door, and it was not very strong.

Effect...... It's the opposite.

"My strength has really grown!" Cao Fei sighed in his heart, this is the case, and it can only be explained by this reason.

Well, let's leave it alone, let's get zombies first!

Three zombies fell to the ground, two on top and one on the bottom, and the zombie with one arm missing was the most unlucky, and it was used as a meat pad underneath.

Zombies will go down the stairs and get up if they fall, but they will move more slowly.

Cao Fei stepped out of the office with an iron-spine spear, and the three zombies were trying to get up from the ground.

That's a fart!

Of course Cao Fei didn't want to give them a chance to get up again, take advantage of your illness and kill you, don't get up, lie down and let me stab ......

I'm poked!

Poke those two ordinary ones first.

Well...... This is a tactic, in case the iron spine spear is not good, it is also ineffective against zombies, then it is too late to stab him first, rather than this, it is better to seek stability, first stab two ordinary zombies to death, and then leave zombies 1v1, even if you can't beat him, you can run out......

So, thinking so, Cao Fei was ruthless and made a move on two ordinary zombies first.

Burst! Burst!

Twice!

Just like holding a bamboo skewer toad, the iron spine spear easily pierced the heads of the two zombies, looking at the iron spine spear inconspicuous, but now that it is used, Cao Fei found that it is very, very sharp, when he used a screwdriver spear before, it was also easy to kill ordinary zombies, but when piercing the zombie's head, there was always a sense of obstruction, and it took a little strength to stab it, and this time, there was a feeling of hot knife cutting butter, and there was almost no feeling of hindrance, and the iron spine spear had already stabbed into the zombie's brain.

"Nice! It's called a weapon! Great stuff! ”

After winning the first battle, Cao Fei's confidence increased greatly, and the direction of the iron-spine spear turned and aimed at the zombie's head.

"Come on, it's your turn!"

Before the words fell, a spear stabbed out, from top to bottom, right in the face of the zombie.

Then, listen to the sound of stepping on a shelled peanut or a hard beetle.

The cuticle on the zombie's face cracked like a spider's web, and a broken hole appeared in the middle - it was the place where the iron spine spear stabbed, almost no hindrance, the iron spine spear had already pierced into the zombie's head, and under the power of this spear, the zombie was like a starfish hit with an electric baton, its neck was straight, its limbs were spread, it shook twice, spit out something from its mouth, and then ...... And he never moved again.

Three lines of small characters fluttered in Cao Fei's sight.

"You kill a normal zombie and get 10 points...... Mission 3 Completion: 6/1000"

"You kill a normal zombie and get 10 points...... Mission 3 Completion: 7/1000"

"You kill a zombie and get 20 points...... Mission 4 Completion: 1/10"

All right!

In fact, it doesn't matter, every time after killing a zombie, there will be such words that jump out to obstruct the eyes, and now Cao Fei's attention is almost on the thing that just spit out of the zombie's mouth.

"What is this?" Cao Fei was puzzled and curious, when he killed ordinary zombies before, he had never seen them.

I saw that this thing was about the same size as a bullet, with edges and corners, a crystal-like shape, dark red, and some dark black stained blood on it, speckled and disgusting.

Cao Fei didn't dare to take it directly with his hands, it was dirty, and it was also for safety, so he turned around and came back, took a rag left by someone in the office, and then bent down and pinched this little thing.

Wipe it, and the dirty blood on it is wiped off.

Pinch it, it's hard, but it doesn't look like metal, and I don't know what material it is.

"Oh yes!" Cao Fei suddenly remembered that when he was looking at the zombie illustrated book before, there was such a sentence in the remarks of zombies, and there was a certain chance to obtain low-level corpse crystals...... Could it be this thing?

Well, that's probably it!

"It's just ......" Cao Fei held this corpse crystal in his hand, looked left and right, and muttered in his heart: "What is this thing for?" ”

He opened the Zombie Book again, but he still didn't see any explanation or explanation on it.
