Damn zombies, how dare they disguise themselves as humans!

"Zhang Yuanshan?"

"How is that possible!"

Luo Tian was stunned.

For a moment, he even wondered if the system had malfunctioned.

But Luo Tian quickly calmed down, and his flickering gaze returned to its calm state.

The system will never make a mistake.

At the very least, none of the people identified in the previous missions were wrongly accused and killed.

This time is unlikely to be an exception either.

Although Professor Zhang Yuanshan, an elderly virologist, was a kind person who instructed the soldiers stationed there to rescue every escaped survivor and distributed the stored food to ensure the survival of all survivors, he was always gentle and kind to outsiders, making it easy for people to develop a good impression of him.

But what about the inner self?

I had only been at this base for a short time and had only met Zhang Yuanshan twice.

No matter how good he feels about you, you can only know a person's face, not their heart.

Perhaps, the appearance of kindness is just a disguise?

In reality, he was vicious and ruthless, which triggered the system's task to identify him as a target for elimination.

"Zhang Yuanshan is in the underground laboratory."

"Should we have the soldiers inform Zhang Yuanshan and then be taken there to be killed, or should we sneak over and assassinate him?"

After a moment's thought, Luo Tian chose the latter.

Killing Zhang Yuanshan when you meet him will inevitably lead to a conflict with the guards and may even alarm all the soldiers in the base.

If the stairs leading up to the top are blocked in the basement and a misunderstanding arises, he could very well be shot dead.

In a narrow passage facing a dense network of fire, stealth is useless.

After getting up and going to the door, Luo Tian had an idea.

His figure vanished instantly, and his vision dimmed at the same time.

After taking a quick look, Luo Tian rushed out of the room and passed by the soldiers guarding the door.

The combined use of the Swiftness skill amplified his speed, allowing him to move like the wind and traverse the long corridor in just four or five seconds.

Next to the staircase in the center of the building

The iron gate leading to the underground laboratory was closed.

Although the door was not locked, there were two heavily armed soldiers guarding the entrance.

If you try to open the door while remaining invisible, you will definitely be discovered.

Knocking out or killing a soldier would also attract the attention of patrolling soldiers.

With only three seconds left in his stealth skill, Luo Tian was preparing to go straight upstairs, revealing himself at the corner of the stairs to wait for the right moment, when the door... suddenly opened.

A researcher in a white coat walked out, holding a document, and went straight to one of the guards, presumably to give some instructions.

Don't miss out!

Without thinking, Luo Tian rushed straight over.

Upon entering the iron gate, just as I sprinted to the corner of the half-staircase, my invisibility ended, and I was immediately revealed.

"That was close."

"But I was lucky enough."

"Waiting outside for an opportunity would not only take a long time, but there's also the possibility of being discovered by patrolling soldiers."

Luo Tian took a slight breath and looked up at the sky.

He had observed earlier that there were no cameras in the spiral staircase.

Even if we had one, we wouldn't use it. The amount of electricity generated by the generator is barely enough to support the laboratory, so how could it be used elsewhere?

Luo Tian slowed his pace and descended a few levels before stopping, waiting for his stealth and speed skills to cool down while keeping an eye on the movements coming from above and below.

Fortunately, both skills have very short cooldowns, only two or three minutes.

Within three minutes, the researcher who had just gone out did not come down, and no one from the underground laboratory came up either.

Just like before, Luo Tian lowered his footsteps and began to descend.

The journey was uneventful until we reached the very bottom.

Turn the corner, and you'll find a corridor lined with laboratories on both sides.

His luck had run out; he couldn't just walk down the corridor unnoticed anymore.

"Phew~"

I took a deep breath to ease my tense emotions.

Next second,

sneak!

Hurry up!

The moment he activated his two skills, Luo Tian's figure circled the corner and sped down the corridor.

Zhang Yuanshan's current location is unknown; he could be in the room where he was previously examined and had his blood drawn, or he could be in any laboratory.

But Luo Tian didn't stop searching; the short 10 seconds he was invisible didn't allow him to search slowly.

Once his stealth ends and he is exposed, he will inevitably find himself in an extremely passive and dangerous situation.

Therefore, Luo Tian's running figure did not stop for a moment.

Sometimes they would avoid researchers who came towards them.

Sometimes, I'm forced to use my sharp skills to enhance my reflexes and dodge the figure that suddenly appears when the door opens.

The destination points directly to the end of the corridor.

Although he didn't know where Zhang Yuanshan was at the moment, there was one place the other party would definitely go.

For example, the room behind that heavy iron door at the end of the corridor.

When he was brought down earlier, Zhang Yuanshan came out from inside and heard the roars of zombies coming from inside.

Therefore, that area should be considered the core of the underground laboratory.

Furthermore, if you make a big commotion inside, it won't get out, making it safe and secure.

Furthermore, if you make a big commotion inside, it won't get out, making it safe and secure.

After dealing with it, open the door and quickly leave stealthily, without anyone noticing.

"6 seconds!"

"5 seconds!"

"4 seconds..."

Luo Tianfei's running figure suddenly stopped in front of the heavy iron gate.

After glancing at the combination lock and rotary lock on the door, he immediately took out the Thunder Blade and went to the door of a room on the right.

Then, while pushing the door open, he drew his knife, preparing to force it open.

With the sharpness of the Thunder Blade, breaking the lock on an ordinary door would be a piece of cake, and it wouldn't make much noise.

However, to Luo Tian's surprise, the door was unlocked and opened with a gentle push.

But he didn't have time to think much, he quickly slipped inside, and immediately closed the door behind him.

"Nobody here?"

"Good luck."

Turning around and quickly scanning the surroundings, Luo Tian, ​​who had just appeared, breathed a sigh of relief.

The room was cluttered with instruments and equipment, clearly a storage room, so it was normal that no one was there.

After catching his breath against the wall and calming himself down, Luo Tian turned around and opened the door a crack, silently observing the heavy iron door diagonally in front of him.

At the same time, they are waiting for the skill to cool down.

Time flies.

More than half an hour later, with a heavy mechanical sound, the iron gate in sight finally opened.

The familiar figure of an elderly man in a white coat also came out.

But just as the other party was about to close the door...

"Clang~"

A crisp sound of something falling came from the storage room next door.

Zhang Yuanshan paused for a moment, then walked over with a puzzled look, pushed open the door of the storage room, and looked around inside, but didn't see Luo Tian standing right in front of him.

Hands-on?

Luo Tian, ​​who was in stealth mode, raised his sword.

At such close range, it could definitely be killed with a single blow.

But this would mean that he would be completely exposed and could be cornered by the arriving researchers and soldiers, or even die in the crossfire.

After some hesitation, for the sake of caution and his own safety, Luo Tian had no choice but to abandon the idea.

Quickly walk past it.

Then we entered through the open, heavy iron gate.

Almost simultaneously, the iron gate behind me was closed, accompanied by the sound of machinery turning.

"Could it be that besides the zombies, Zhang Yuanshan is the only person here?"

Standing behind the door, Luo Tian held his knife and examined the brightly lit, large room in front of him.

There were no researchers or soldiers in white coats in sight, only zombies.

To be precise, they were zombies locked in iron cages, lined up neatly in rows, stretching far into the distance, numbering at least several dozen.

In the center area were several iron bunk beds.

On three of the beds, three people were lying motionless.

As he walked over, Luo Tian was stunned the moment his gaze fell on the figure on the bed, and his face instantly darkened.

The person in the bed is familiar.

A man, a woman, and a little girl.

Moreover, the three of them had ashen faces, with visible purplish-black veins bulging out.

These are symptoms of infection with the zombie virus.

But the family of three had just seen each other not long ago, and they were perfectly fine at the time. How could they have been bitten and infected with the virus?

The answer is obvious.

If you weren't bitten, then the only possibility is that you were injected with the zombie virus.

"Damn scum!"

Luo Tian gripped the Thunder Blade tightly in his hand, his eyes slightly reddening as he looked at the little girl on the bed who looked a lot like his younger sister.

The little girl's clear, crisp voice echoed in my mind.

Big brother, do you need a shot?

Big brother, I have nothing to trade with you.

Big brother, I won't take your eggs for nothing. I'll tell you a story later, and I'll also share some extra food with you every day...
