Yun Xinyue quickly got the news from the helicopter that picked them up, and she wanted to go to a building in the city that was about to fall first, and save a few people, they are a multi-person helicopter, which can kill up to eight people, in addition to the two pilots in the main control room, plus two soldiers, and them, there are two positions, which are prepared for another female doctor.

"You two are also supernaturals!" A soldier surnamed Gao asked.

Yun Xinyue and the two nodded.

"Please help guard the surroundings for a while, Xiao Li and I will go down to save people"

"I'll go with you!" Bo Yibai felt that he should help a little."

"That's not good, you're guests"

"I'm a fifth-level spatial control ability, I can help you and save you at a critical moment!" Bo Yibai said his ability, which made the surname Gao very surprised and delighted.

"That's good, thank you!"

The helicopter soon stopped on a wide area of land with no one on the building.

Yun Xinyue and another plane pilot came down to guard the surroundings, fortunately, during the day, the zombies would not run out, but if they had to go down from the rooftop to the building, it would be dangerous.

"The building is dim and dark, and the power has been completely cut off the day before yesterday, even if it is daylight inside, it is more dark, and it is most likely to breed powerful zombies."

"Everyone must be careful"

"But don't worry too much, here's the layout of the building, everyone bring this night vision goggles, there are our goals this time."

Bo Yibai brought it according to his words, and Yun Xinyue also brought it.

The three-dimensional image of the building is shown on the lenses, and there are many green dots that look like their location.

"The white dot is below, there are thirty-five floors on this floor, and our goal is the laboratory on the twenty-fifth floor, where we are looking for a doctor named Zhang Caiyun, this is a photo, everyone remembers it clearly."

"Hmm"

"Remember, if you see a red dot, run immediately"

Everyone nodded, and the group of three opened the door of the rooftop, and after the three of them left, Yun Xinyue hurriedly closed the door and blocked it with a wooden stick.

Yun Xinyue stared nervously at their green dots.

Bo Yibai only held a short knife in his hand, because in this kind of place, he could try not to make a noise, so he felt that he could not use a weapon of destruction with a loud sound like a gun.

Bo Yibai and the three of them walked down carefully, the bottom of the stairs was clean all the way to the fifth floor, and when they reached the thirtieth floor, there were a lot of blood stains, and a large group of zombies were tearing a ball of flesh and blood on the stairs, looking down, at least several times the zombies were on the stairs, below

The tall soldier stretched out his hand to stop the person behind him and gestured in a low voice.

"Walk out of the building!"

The three of them opened the security door quietly, but unfortunately the security door was old and made a "squeak" sound, which was amazing, and the zombies downstairs heard the sound, and they all roared and raised their heads, and immediately rushed towards them.

Bo Yibai hurriedly closed the door, picked up the things and blocked them, but fortunately, the door was still strong and blocked.

Bo Yibai and the three of them breathed a sigh of relief, but they were afraid that this door would not last long, they needed to find another way out, and the only way out now was the elevator, but it was already out of power.

"Take the elevator or outside?"

"There are five more floors, take the elevator shaft," the tall soldier decided.

Fortunately, the elevator is at the bottom when the elevator hall is opened, so they don't have to worry about falling down from above, they can climb down the ladder.

The three of them watched for a while and began to walk down, and when they reached the twenty-fifth floor, they saw many zombies dangling around the twenty-fifth floor as soon as they opened the gap in the elevator door.
