After going around the chemical factory, after determining that the highest evolved zombie was the third order, Yang Yi was relieved.

"Third-order vs. third-order, the doppelganger is definitely on the side that has the upper hand."

The zombie clones have the wisdom of human beings, and the fusion of the giant and the swift one, the overall strength is far higher than that of the other third-order evolutionary zombies, and these third-order evolutionary zombies, Yang also has absolute certainty to step on them, pick their third-order software, and contribute to the fourth-order.

The tallest building found in the chemical plant is the office building of the chemical plant.

Standing on the eighteenth floor of the office building, under the afternoon sun, the eyesight of the doppelganger can look far away.

The entire chemical plant area is in full view, and there are signs of zombie activity everywhere on the streets and alleys. Yang Yi, who is accustomed to zombie groups, can confirm at a glance that the zombies on the streets are much looser than those in the city.

Yang is also a little entangled, how to let zombies gather in such a large area?

The sound is a good idea, but it seems to be a little worse than blood.

The zombie's thirst for blood, in Yang Yi's opinion, is beyond everything.

……

It took a day for Yang Yi to collect thousands of milliliters of blood in the settlement, as well as a few explosive packets, and some firecrackers that Yang Yi specially had people make, drive a pickup truck, and secretly deliver them to the vicinity of the chemical plant.

After returning to the settlement, he immediately controlled the clone to take out the hidden blood.

Carrying a large bag of things back to the tallest office building of the South China Chemical Plant, it was another afternoon. When he came, Yang Yi had already let Wang Meng understand that there was no team in this area, so he could rest assured that Yang Yi would implement this plan.

Of course, blood alone is not enough, it is perfect to match the sound.

took out a bunch of firecrackers, Yang Yi took out a lighter and began to toss.

The reason why it is said to be a toss is because the body of the doppelganger is too big, and the fingers are bigger than a lighter, and it takes a little skill to light the fire.

After lighting the lighter, the firecracker was lit, and there was a deafening "crackling" sound, which was heard in the eighteen-story position. Standing on the edge, the doppelganger carried a firecracker and hung on the edge of the building, making a louder noise.

As soon as the sound of "crackling" came out, you could see the zombies around you tickling and rushing towards the location of the sound.

For Yang Yi, this is not enough.

Taking out hundreds of milliliters of blood from the bottle, Yang Yi slammed it into the air, the blood flew in the air, and went away with the wind, and a strong smell of blood appeared in the air; Moments later, the blood turned into raindrops and fell onto the streets, appearing among the buildings.

The extremely sensitive nose, the thirst for blood, from the moment the blood appeared, the zombies became more violent and more scratchy.

On the streets, the surging zombies rushed forward desperately, staggering and half-running.

Yang Yi took out some more and splashed them directly on the glass window on the roof of the building, letting the blood flow down the glass window.

In this way, the smell of blood is even stronger.

Sharks can smell blood from a few nautical miles away, and the zombie's sense of smell Yang is estimated to be within a kilometer or two, which should not be a problem. Under this combination of blood and sound, it has become simple to mobilize the zombies of the entire South China Chemical Plant.

When the third firecracker was lit, the lower part of the office building was surrounded by zombies, densely packed, and when it swelled, it looked like an undulating ocean.

The door of the office building was closed.

The zombies that appeared were desperately slamming into the closed gate, making a "whining" sound, pushing and slamming into the gate again and again, making the gate make a series of "click" sounds. Gates made of fiberglass like these, with an impact of this intensity, can't last long.

As far as the eye can see, on the streets outside the chemical plant, zombies are also pouring in this direction.

The sound of "crackling" has become the best navigation, and blood has become the most attractive thing for zombies, guiding zombies to continue to flock here.

Tens of thousands of zombies gathered together, and many of them have not yet been lucky enough to see them.

Imagine being at school with thousands of people standing on the ground, all of them magnificent.

And now, tens of thousands of zombies gathered, what kind of grand occasion is it?

Methods like using blood and voice are not a big deal in clones. But with the replacement of survivors, it is definitely a catastrophe. What kind of fate will a team be surrounded by tens of thousands of zombies? Don't think about it, it can only be food for zombies.

The doppelganger is different, it can do all of this and swagger away.

After the third firecracker was set off, the shadow of evolved zombies appeared on the street, either squeezing through the ordinary zombies, or climbing past the buildings on the side of the street, approaching this office building. Yang Yi visually inspected it, and there were at least more than ten evolutionary zombies that could be seen, and the order was between the first and third orders.

Half an hour is enough to attract more than ninety percent of zombies.

With the appearance of the Evolution Zombie, the glass door was smashed by a second-order giant, and countless zombies poured in through the gap.

"Next, it is to use the restlessness generated by the blood to make the zombies make a 'whine' sound, so as to guide countless zombies to walk away with the blood and lure them away from this chemical factory."

The characteristics of zombies are that after discovering some breath of life, they make a predator-like "whine" sound, and under this sound, they will get countless zombie responses, and then follow these sounds, constantly attracting more zombies. When it comes to the breath of life, what is thicker than blood?

After getting off this office building, Yang Yi killed zombies all the way.

On the street, the number of zombies was even more terrifying, one after another, there was almost no gap, Yang Yi controlled the clone, relying on the cow and horse to squeeze away these zombies, and went towards the outside of the chemical factory.

There is blood attraction in the office building, and Yang will not be targeted now.

It took half an hour for Yang Yi to squeeze out of this group of zombies, this situation, even Yang Yi was a little unbearable, once he faced it, Yang Yi even had a creepy feeling.

Squeezed out, on the office building, there were already a large number of zombies pouring into the ceiling, they were completely unconscious, only knew that they were rushing towards the blood. The blood was poured by Yang Yi on the glass window of the building, and if the zombie wanted to touch it, he could only climb on the railing......

Looking at the zombies that fell from the office building like dumplings, Yang also had a feeling of speechlessness.

A zombie who just wants to get blood is like committing suicide by standing on a cliff, and one by one falls down. For unconscious zombies, they don't know what danger is, and falling down of the same kind has no effect on them.
