Institute of Biology

After stretching his muscles, Xiao Feng collected the Bloodfang Wild Boar.

Given his current physical condition, he knew he couldn't continue to fight.

He decided to retrace his steps and head back in the direction of Yu Lin City.

Xiao Feng didn't use the "Instant Return" skill right away.

He wanted to see if there were any mutated pigeons around.

If there were, he thought he might be able to catch a few and make some delicious roast pigeon.

However, he couldn't find any mutated pigeons during his journey.

As Xiao Feng was about to use his "Instant Return" skill, he suddenly saw a jeep approaching from the distance.

"Their direction seems to be away from Shelter No, 9," Xiao Feng thought to himself as he hid and observed the newcomers.

The jeep came to a stop, and a group of people got out.

Three of them were armed with firearms, and two of them had machetes. They looked around and then entered a manhole.

"Lately, there have been frequent sightings of survivors from Yu Lin City. Who are these people now?"

Xiao Feng wondered.

"Anyway, I can use my 'Instant Return' skill, so I might as well follow them and see what they're up to," he thought.

Thinking of this, Xiao Feng immediately put away his weapon and stealthily followed them.

Ducking into the sewer, Xiao Feng listened to the distant sounds and quietly trailed them.

In the sewer, they were heading in a direction that was not towards the restaurant. Since they were not on the surface, Xiao Feng didn't know where they were heading.

Clank, clank, clank!

Suddenly, gunshots echoed from the front.

"Mutated rats! Run!" 

"Back through the manhole we just came from!"

Hearing the commotion, Xiao Feng immediately looked upward and noticed a nearby manhole leading back to the surface. He decided to take it.

After climbing out, he observed the surroundings and then stealthily hid inside an abandoned car. Shortly after, the group of people emerged from the manhole and sealed it.

Squeak, squeak, squeak...

The sewers were filled with the sound of rats. One of the men pulled out a grenade and tossed it into the manhole.

Boom!

An explosion sent the manhole cover high into the air before it crashed down again.

Then, after covering the manhole, they left the area.

Slowly, he extended his head, and Xiao Feng saw them heading towards a nearby research institute.

"These guys definitely aren't here for supplies!" 

Xiao Feng can be sure.

Because most search teams, after entering the Yu Lin City, would head to places like supermarkets or convenience stores as a priority.

But these few people are heading towards a research institute.

"What are they up to?"

At this point, Xiao Feng's curiosity was thoroughly aroused.

At the same time, inside the research institute, the people from Shelter No. 9 quietly watched what was happening downstairs and outside.

And after they had withdrawn their gazes, Xiao Feng stepped out of the car.

Subsequently, after Xiao Feng got out of the car, he slowly followed suit into the research institute.

Coincidentally, they hadn't noticed Xiao Feng following behind them. But the group already inside the research institute did.

"Is that group of people from Shelter No. 8, bro?"

Beside him, Bai Mang asked with a solemn expression.

"Yeah! They're already downstairs, and leading the way are the Zhang brothers, Zhang Lei and Zhang Dian!"

Bai Mang nodded.

"What should we do now?"

Bai Mang asked nervously.

"Hide and let them deal with the guy upstairs!"

Bai Mang thought for a moment, then took everyone into hiding.

The people from Shelter No. 8, after entering the research institute, immediately stopped.

Seeing the dead zombies on the first floor with gunshot wounds, the leading man who was holding a gun frowned, "Someone's been here!"

"The zombies haven't been dead for more than an hour; there's definitely someone on the upper floors!"

Another man confirmed.

Upon closer inspection, the two men holding guns were, surprisingly, twins.

Upon hearing this, the other three men with guns immediately adopted a combat stance and slowly headed towards the staircase.

The Zhang brothers, in fact, went to the bathroom.

They plan to head to the fourth floor after the first, second, and third floors showed no abnormality.

Upon arrival, the other three men lowered their weapons and approached the open spaces between the office rooms on the first floor.

Empty, one room at a time...

When they had searched all the rooms one by one and felt relieved that they found nothing, they noticed something amiss.

The zombies had been killed on the first floor, which meant someone had entered ahead of them.

But there were no abnormalities on the first floor, so were they on the second or third floors or higher?

Thinking of this, they no longer continued up the stairs hastily and instead searched and cleared one floor at a time.

At this moment, on the third floor, Bai Mang and the others heard footsteps approaching from downstairs and couldn't help but sigh in relief.

"Bro, they must know there's someone on one of the floors, they must be searching the lower floors!"

Bai Zhi spoke in a hushed voice.

"What should we do now?"

"They can't go upstairs without confirming if there are other people on lower floors; they won't go upstairs if they can't be sure!"

Bai Mang said, deep in thought.

"So if we hide here, we'll definitely be discovered!"

Bai Mang said, and after a moment, he fell silent.

But a moment later, his eyes lit up and he quickly came up with an idea, "I've got it!"

Then, Bai Mang instructed Bai Zhi and the others, "Stay here and don't move, I'll go bring the zombies from upstairs down!"

As long as they met and fought, Bai Mang and the others would be safe.

Bai Mang tiptoed to the fourth-floor staircase and then took out a hand grenade. He tied a thin rope to the safety ring and then tied it to the railing.

The fourth floor had zombies moving back and forth.

Bai Mang tied it to a must-pass path and then withdrew back into the bathroom.

Time passed slowly.

As they waited silently, they suddenly heard an explosion from upstairs, and Bai Mang immediately smiled.

At this moment, the twins who had finished checking the second floor and come to the third floor immediately focused their attention on the fourth floor.

"They're on the fourth floor! Let's go!"

After saying that, the five of them charged towards the fourth floor without hesitation.
