Doomsday Rebirth: The heroine comes back with the system

She clutched the wall above the window tightly with her hands.

This equipment also comes with a pair of gloves with a suction design that can stick tightly to objects.

Yin An was agile and climbed to the third floor.

As soon as he reached the third floor, a zombie rushed out of the window and attacked Yin An fiercely. Yin An reacted quickly and kicked the zombie down with his legs, followed by a dart to stab it.

The zombie was shot in the head and fell down.

After Yin An collected the crystal core, he discovered that there were several zombie corpses in the corridor behind the window.

She moved her fingers slightly and collected all the crystal cores in the corpses into the space.

There's someone here!

Yin An narrowed his eyes slightly.

She climbed up one floor and sure enough, she saw a tall man in black casual clothes and a hood fighting with zombies. He was extremely agile and relied entirely on his own body to fight.

I saw that his left hand was tied with an iron chain, which was covered in blood, and his right hand was tightly holding a fruit knife.

After a beautiful cross-cut, the last zombie on the fourth floor fell.

He tilted his head slightly, and his pair of black eyes hidden under his bangs looked directly at Yin An. His nose was straight, his features were sharp, and his lips were tightly pursed.

There was no expression on his cold-blooded face.

Qi Ye?

Yin An's heart moved. When she met him in her previous life, he was already a member of one of the two strongest teams in the special operations zone of the national base.

His Winter Team and Liu Qingqing and Xie Yun's Supreme Team are ranked first in the base.

Whether it's resources, contribution value, or that terrifying combat power, they are all very powerful.

He is aloof and gloomy person, extremely powerful, and possesses terrifying special powers of dark and poison.

But at the moment, his supernatural powers are still very weak.

What Yin An could be sure of from his actions just now was that he had awakened the dark power, but it was so weak that he didn't even notice it.

He should be trying to save his only surviving sister Qi Mei at this moment, but according to the description in the book, he failed. By the time he killed all the zombies in the corridor on the eighth floor and rushed to the door of his sister's dormitory, Qi Mei had already died at the hands of the zombies.

He was heartbroken and became even more withdrawn from then on.

Yin An's heart moved. This was one of the men Liu Qingqing wanted to snatch away.

If I help him now, given Qi Ye's aloof but righteous character who will repay favors, he will definitely not become my enemy in the future.

Yin An knew very well that Qi Ye didn't like people who talked a lot, so she said nothing.

Quickly climbed up to the fifth floor, the sixth floor, the seventh floor...

When we reached the eighth floor, it was packed with zombies. The number of zombies was almost the sum of the seven floors below!

All the zombies were crowded in the corridor, pushing towards the innermost dormitory door.

Except for the innermost dormitory, the doors of other dormitories were all open, and inside were either students who had been bitten to death but had not yet mutated, or zombies!

The door to the innermost dormitory was also in danger.

Qi Mei should be in there!

It's time to hunt.

A hint of cruelty flashed across Yin An's beautiful eyes. He kicked into the aisle and knocked down several zombies. All the zombies immediately turned around and ran towards Yin An!

She squatted and did a spinning kick. Her hands moved extremely fast and the dagger wrapped in lightning swept across, chopping off the heads of a few zombies.

The zombies that followed rushed over again. Yin An shot out a grappling hook and climbed on the ceiling, and released darts with lightning. He harvested another area.

[Exercise volume reaches the standard, strength +1, toughness +1]

The system's announcement became background noise.

Yin An shot a grappling hook at the group of zombies. The grappling hook pierced through three zombies and nailed them to the tiles on the ground.

Tighten up!

Yin An leaped towards that place, the dagger in her hand flying, cutting the skulls of the zombies along the way.

All this is done in just one minute.

Her moves were fast, accurate and ruthless, only chopping off heads!

Yin An felt severe pain all over her body, but she gritted her teeth and held on.

Forbearance and persistence have long been her habits. She has relied on this ruthlessness to get through countless desperate moments!

The zombie corpses in the entire aisle were piled up in three layers, and the zombies at the back were still pushing forward, as if Yin An was a piece of mouth-watering fat meat.

Yin An stretched his muscles and strode towards the group of zombies, taking in every subtle movement of the zombies on both sides with his peripheral vision.

Lightning burst out from her right hand, sending electricity everywhere she went, and she used the dagger in her left hand to cut heads.

Six minutes later.

The last zombie also fell to the ground.

Yin An took a deep breath, supported himself on his knees and took a few deep breaths, trying to calm his trembling hands.

The system's announcement is still ringing.

[Exercise volume reaches the target, physical fitness +1, speed +1]

The door beside him was slightly opened, and a pair of frightened eyes met Yin An's.

Then the dormitory door was opened, and the girl immediately pulled Yin An in.

She had not yet recovered from her shock and stammered:

"You... you just now... your left hand, your right hand, what about the zombies outside?"

"They are all dead." Yin An said calmly.

She looked at the woman in front of her, who was wearing loose casual clothes. She was very tall, a few centimeters taller than herself, at least 175 cm tall, and had a ponytail.

She has the looks of a sporty girl, giving people a feeling of vitality and generosity.

"My name is Qi Mei, thank you for saving me!!!"

When the girl heard Yin An's words, she immediately bowed to her and thanked her sincerely.

"No need." Yin An said lightly.

[Beep, the plot has been successfully changed and Qi Mei has been saved. It is speculated that this move will pay off in the future! ]

The system's voice sounded, Yin An had no expression. She had already thought about it, saving Qi Mei would only bring benefits and no harm!

She won't do anything that has no benefit now!

There was some movement downstairs. It seemed that Qi Ye was coming soon.

After the superpowers are awakened, a person's five senses will become stronger than before.

Seeing that Qi Mei's lips were cracked from dryness, she pretended to take out a small bottle of mineral water from her pocket, but actually took it out from the space, and threw it to Qi Mei. Qi Mei was even more moved. She thanked her several times, opened the lid of the mineral water bottle, and drank it all in big gulps.

Looks like he's been thirsty for a long time.

Yin An turned and walked to the window in the corridor, looking at the doctoral research building opposite.

There was not much distance between the research building and the dormitory building. Yin An estimated it was about four meters.

You can't see inside the doctoral building through the glass because it is reflective. Yin An took out a red paint and sprayed a big X mark on the window.

Just at this time.

Qi Ye rushed forward.

He saw zombies everywhere, and a hint of surprise flashed across his nervous eyes.
