Because they didn't know if there were any Zerg dormant nearby, all Tang Yu's group didn't dare to shout loudly at will, so they could only search one room after another.

It's a bit slower, but it's safe.

Otherwise, shouting will attract dozens or hundreds of zergs, even if all of them are first-order zergs, it is not for fun.

While looking for it, Tang Yu also thought that if he could use the super life detector, he would not have to worry about whether there were Zerg dormant nearby.

It's a pity that Chen Yumei and Wang Yueyue are followed by him, so he has no choice but to dismiss this idea.

Soon, on the second floor, all the rooms with open doors were carefully searched by Tang Yu's group, and not even a single figure was found, and there was no body, so they must have fled.

So, they entered the emergency passage again and prepared to go to the third floor.

As soon as he took two steps, Tang Yu accidentally lowered his head and found some abnormalities.

I saw that on the steps of the staircase, on the handrails, and on the wall of the wall, there were some friction marks of different thicknesses, and the outline of these marks was still very clear, which should have been left not long ago.

Tang Yu thought that it would leave scratches in the emergency passage, so it meant that the volume of the things passing through here should be very large, otherwise there would never be friction marks.

"Could it be the Zerg?"

Tang Yu thought to himself, his heart was shocked, and he felt that this guess was very possible.

I also know that the Zerg will definitely not take the elevator, and the only way for them to enter the upper floors of the building is through the emergency passage.

Given their sheer size, it is not surprising to say that there will be traces left through this not spacious emergency passage, so this speculation is very likely.

Then, Tang Yu told Chen Yumei and Wang Yueyue about his discovery and speculation, and the two of them also felt that it was very possible, so the three of them were more vigilant.

Since the traces in the passage prove that there are indeed Zerg who passed here not long ago, it means that there are indeed Zerg in the upper floors of the building, and this discovery is enough to make them doubly vigilant.

Sure enough, before he took two steps, Tang Yu stopped, his ears moved, relying on the keen five senses of the ability, he heard some very subtle sounds that ordinary people could not hear.

"Shh

Tang Yu turned his head and gestured to Chen Yumei and Wang Yueyue, who were four or five meters behind, motioning for them to stop here, and then walked up the stairs alone.

Out of caution, Tang Yu only took one step at a time, his breath was held, his voice was so subtle that even he couldn't detect it, and he held a machete tightly.

In this way, step by step, after passing through the corner of a floor, Tang Yu saw an extremely bloody scene.

At the exit of the third floor of the emergency passage, the wall and door were all stained red with blood, and there was a zerg eating a corpse.

The corpse had been gnawed by the Zerg beyond recognition at this time, and only a blur of flesh and blood could be seen, and it was impossible to distinguish between men and women, old and young.

That Zerg was different in size and appearance from ordinary Zerg, and it was exactly the same as the Zerg Strange Species that Tang Yu met in the wilderness that night, but it was smaller than the latter.

First-Order Wonders!

Tang Yu accurately guessed the identity of this zerg with just one glance.

Zerg find and track their prey, mainly relying on their sense of smell. Their sense of sight and hearing is not much better than that of the average human being.

If it was in the wilderness, without the cover of a high-level aura shield, Tang Yu would definitely be discovered by it if he was so close to a Zerg strange species.

At this time, although there is no high-level breath shield, don't forget, this is a city where humans live, not in the wilderness, the smell of people in the air is everywhere, therefore, the sense of smell of the Zerg has been greatly affected and has become difficult to use.

In addition, at this time, it was facing away from the corridor and could not see Tang Yu, and Tang Yu tried his best to control himself not to make a sound, causing Tang Yu to be seven or eight meters behind it, but it did not find it.

Seeing that it was still gnawing on the corpse, Tang Yu couldn't help but think of the miserable deaths he had seen along the way, and his eyes were also red, and a wave of anger arose in his heart.

"Chop and go."

Tang Yu gritted his teeth and scolded angrily, and at the same time quickly rushed towards the strange species, kicking and jumping, and flew over nearly ten steps.

Tang Yu no longer continued to hide himself, that strange species, through hearing, heard the wind brought by Tang Yu's actions, and at the same time, discovered Tang Yu.

As soon as it raised its head, before it had time to turn around, Tang Yu's long-brewing spiritual impact had already bombarded its spirit without reservation.

With the mental strength of Tang Yu's second-level ability, using a spiritual impact to attack a first-order strange species was enough to make it lose consciousness and remain motionless for five seconds.

However, Tang Yu wanted to get close to it, across this distance of seven or eight meters, where could it take five seconds.

In the midst of the anger, under the explosion of all his strength, Tang Yu only took two seconds to rush behind this strange species, and then the machete in his hand was cut down mercilessly.

A knife slashed at the back of this strange species.

The advantage of the strange species is that they have strong attack power and fast speed, and in terms of defense, they are not even as good as a first-order ordinary zerg.

The machete in Tang Yu's hand could tear through the hardest skull of the first-order ordinary zerg, and it was naturally not a problem to break through the defense of this first-order strange species.

A green glow of blood flashed on the back of the strange species.

Tang Yu slashed the spine on the back of this strange species with a single sword.

This incomparably terrifying pain stimulated this strange species to wake up in advance before it arrived five seconds.

However, before it could fight back, Tang Yu kicked its broken spine with all his strength, kicking it straight out, and crashing head-on into a wall three meters away.

Tang Yu's eyes were red, he clenched his teeth, and he didn't let go of this strange breed at all.

Immediately after that, he raised the blade, and the tip of the knife went straight through the back of the strange beast's head, and under the impetus of the huge force that erupted from the palm of his hand, it pierced through its entire head, and finally even inserted an inch into the wall.

In this way, this first-order strange species was nailed to the wall by Tang Yu with a machete.

If you think about it, it's also a nest.

Changing to another second-level ability, with its terrifying speed and strong attack power, there is no problem at all to deal with it, and there is even the possibility of killing it.

Because it is a strange species of the Zerg, it is one of the powerful rare insect species.

In the Zerg, the status of rare insects is equivalent to the superpower among the abilities, who can challenge beyond the level and are extremely powerful.

It's a pity that it bumped into Tang Yu today.

Tang Yu, who has the fruit of mental power, is the nemesis of speed, and naturally he is also the nemesis of the Zerg Strange Species!

Tang Yu clenched the handle of the knife with both hands, panting violently, and when the tip of the knife pierced into the insect brain, the insect blood splattered out of the wound stained his body and face.

But he didn't seem to notice the smell of the insect's blood, he didn't seem to smell it, but his eyes were red and he kept panting.

This state lasted for ten seconds before Tang Yu took a deep breath and gradually calmed down.
