The security patrol personnel were stunned by the scene. They didn't understand why the leadership would open the air-raid shelter door without their knowledge, nor did they understand what the Noah's Ark project was.

The first floor of the air-raid shelter is a resettlement area, where nearly 100,000 survivors live.

Now that the air-raid shelter door is open, the mechanical voice broadcast by the Imperial Communications Department through loudspeakers attracts the remaining zombies outside the shelter. The survivors frantically head towards the second basement level and even deeper floors.

The entrance to the second basement level was crowded with people trying to escape.

Everyone rushed forward, refusing to give way, and a stampede quickly broke out. Even the car that Qiao An'an and her companions were in was overturned by the crowd.

The soldier who had been knocked to the ground by Tang Xin woke up again. When he woke up, he saw a blue-faced, fanged zombie rushing towards him.

Before the young soldier could react, he was already pounced on by the zombie.

In despair, a gunshot rang out overhead, hitting the zombie in the head, and the zombie collapsed to the ground.

The young soldier looked up and realized that it was his Commander Tang who had fired the shot. The car that Commander Tang was in had overturned, and she had just leaned out of the car. Even so, Commander Tang still did not forget to save him.

After Tang Xin shot the zombie that was trying to pounce on the soldier, she took several boxes of vaccines out of the car and said to the still-stunned security patrol personnel, "One vaccine per person. Those who have been vaccinated will come with me to kill zombies!!!"

The security patrol personnel, who were initially quite confused, suddenly felt they had found a pillar of support.

The young soldier who was saved by Tang Xin was deeply moved.

However, the number of vaccines is limited.

There was no way to inject everyone, and soon the survivors who hadn't been injected and were slow-moving were bitten by zombies and turned into zombies themselves.

Qiao An'an said to Tang Xin, "We don't have enough people. If this continues, we will be wiped out. We must move to the second floor immediately."

Tang Xin: "You take my sister and the others to the second floor. I'll stay here and hold off the zombies."

Tang Rui panicked upon hearing this. Even though Tang Xin and the others had been vaccinated, and even though they wouldn't turn into zombies after being bitten, they still couldn't withstand so many zombies biting them one by one. She rushed forward to grab her sister, saying urgently, "No, you'll die if you stay here."

Tang Xin pushed her sister Tang Rui away: "If we don't stay, the zombies will go into the second basement level with you!"

Tang Rui: "But you'll die!"

The moment Tang Xin became a soldier, she was prepared to die at any time. She took one last look at Tang Rui and led her soldiers towards the zombies. They had to give the people behind them enough time to enter the second basement level for refuge.

Tang Rui wants to pursue her younger sister.

Xiao Wenshan hugged her tightly, saying, "This is the time Tang Xin and the others bought for us with their lives!!!"

Of the approximately 100,000 people in the resettlement area, only 20,000 to 30,000 eventually made it to the second basement level.

After entering the second basement level, everyone discovered that the door to the second basement level could not be closed.

It was undoubtedly the work of that guy who said he was going to implement some Noah's Ark plan. Fortunately, there was strength in numbers, and they used the cabinets on the second basement floor to block the entrances and exits completely.

After blocking the entrances and exits, Xiao Wenshan immediately released the pharmaceutical workers he had stuffed into the cabinet and asked them to help make vaccines so that each survivor who entered the second basement level would receive one.

The workers finally realized who the bad guys were, and they all rushed to help.

However, those bitten on the underground level quickly turned into zombies.

The gunshots from Tang Xin and her group gradually faded away.

The gunshots had barely stopped for a moment.

The zombies started ramming the door on the second floor.

Xiao Wenshan said to everyone, "We are making a zombie vaccine for everyone, you must hold the door open!!!"

Some of the survivors listened to Xiao Wenshan's words and desperately held the door shut.

Many more people ran straight into the third floor: "There are so many zombies outside, even with a vaccine, we might not survive!"

Normally, access to each floor requires authorization.

For example, survivors on the first basement level do not have permission to enter the second basement level, and workers on the second basement level cannot open the third basement level door, but the door to the third basement level is currently open.

Tang Rui was somewhat surprised: "This...how is this possible?"

After what just happened, Qiao An'an wasn't surprised at all: "I'd guess that the doors on the first to fourth floors can be used normally. The so-called Loya Ark Project is probably going to turn all the survivors in the safe zone into zombies."

Tang Rui: "Are they going to turn into zombies themselves?"

Qiao An'an's biggest worry right now is Ya Ya's safety, so she went straight down to the third basement level to find Ya Ya: "People are selfish. Don't be fooled by their claims that humans have destroyed the Earth and that they want to eliminate humans to protect the planet. They themselves are unwilling to die. If I'm not mistaken, those people are already hiding on the fifth basement level, which we can't get into."

Tang Rui led the way.

Chi Xiaoyu followed, carrying a bow and arrows.

Grandpa Gu followed behind the two, leaning on his sniper rifle.

Li Jianguo and Yan Ling stayed behind to help Xiao Wenshan.

The first floor is the largest part of the air-raid shelter, the second floor is smaller than the first floor, the third floor is even smaller, and so on.

After the survivors from the second floor entered the third floor, they quickly filled it up. Once there was no more room, they moved on to the fourth floor.

Tang Rui was almost pushed over by those people. Qiao An'an helped Tang Rui up and pushed through the crowd. They finally found Tang Rui's previous room. Only Gu Bei and Xu Ruoyu were in the room. Ya Ya, Da Hei and Ye Jing were nowhere to be seen.

Gu Bei rushed over as soon as he saw Qiao An'an and the others: "Grandpa, Aunt An'an, Sister Xiaoyu!!!"

Qiao An'an: "Where are Ya Ya and Ye Jing?"

When Qiao An'an asked, Gu Bei answered truthfully: "After you left, people from the research department came to find Ya Ya and said they needed her blood to develop a vaccine against the new zombie virus, and then they took her away."

After Ya Ya left, Ye Jing returned with the vaccine.

He asked us where Ya Ya had gone, and I told him that Ya Ya had gone with people from the research department to make a new vaccine against the zombie virus. After hearing that, he asked me if the people in the research department were bald. I said that their heads looked bald, and then he said something bad had happened, and he took Da Hei and chased after them.

I originally wanted to go with him.

He told me to wait here for you to arrive so he could tell you about it.

Tang Rui's face was full of worry after hearing this: "The bald guy Ye Jing mentioned is our department director, Tian Mingbo. He's the one who injected me with the virus and put a collar on me, trying to turn me into something like those monsters outside."
