There was black smoke rising from the downstairs, and Da Fei knew that the flammable materials that had been placed below had begun to burn. In addition to the rancid smell in the air, there was also the smell of stinky salted fish burnt.

Black smoke rose along the façade of the street, and everyone began to look for a way to the south on the rooftops. This building is built next to the adjacent building, and the two buildings are either connected to each other or have very little space in between.

The clothes racks on the roof of the building were blown to the ground, and the clothes hanging on them had become dirty and messy under the wind and rain, and after the sun had bothered, there were even small holes in some places. The clothes covered the ground and seemed to be glued there, and a few privately built sheds stood not far away, making the roof look a little cluttered.

A loud "boom" came up from under the building, Chen Bin and the others felt a slight shock to the ground under their feet, and then saw a thick smoke rising from the fence on the roof.

"Damn, the gas canister exploded," Da Fei plucked his ears with his fingers, and the explosion just now made his ears tingle.

"it!" Qiao Xingyu was also taken aback by the sound of the explosion, the last time he felt the shock of this explosion was on the night of the fire in the Jiafu supermarket.

The wind carried the smoke that was running down the road in this direction, and everyone quickly avoided the direction where the smoke drifted away, and then began to look for a suitable way out.

Seeing that the door of a nearby shed was unlocked, Bian Ce walked over and pushed the door. When the door was pushed open, a rancid smell suddenly came to his nose, and Bian Ce took a few steps back, almost choking on tears.

"What's wrong?" Da Fei asked, as soon as he took two steps in the direction of the door of the shed, he had to cover his nose with his sleeve, "It stinks." ”

Resisting the strong rancid smell, Da Fei came to the door, because it was on the roof of the building, the light in this shed was not bad.

Several bodies lay on the ground, all of them highly decomposed, and in some places even bones were exposed. There was still some thick mucus under the corpse, which should have been completely dried up after the previous decay and water. There were a few flies lying on the windowsill, and when the door opened, the sound alarmed them, and the flies flew up with a "buzz" and ran towards the door.

After seeing the situation in the shed clearly, Da Fei quickly closed the door.

"There are a few dead people inside, all of them are so rotten that they can't see human shapes," Da Fei let go of the hand covering his nose and told everyone what was going on inside.

Chen Bin nodded, it is not uncommon for there to be dead people or zombies in the house, everyone has seen such a scene countless times after the disaster. He began to look around on the roof of the building, trying to see if he could get to the top of the next building.

"This shed blocks the low wall next to it," Qiao Xingyu kicked the shed where Bian Ce opened the door just now, and there were a few "clang" sounds on the iron wall of the shed, he went around to the side and looked, "It turns out that this shed was built to block the low wall between the two buildings." ”

"How about climbing up on it and jumping over?" Chen Bin asked.

Qiao Xingyu looked up at the material of the roof and shook his head, "They are all asbestos tiles, and the load-bearing capacity is very poor." ”

"What then?" Bian Ce was a little anxious, he just went to the fence facing the street to observe the situation below, the road outside the restaurant was already crowded with zombies, although the previous explosion lifted out some of the zombies in the lobby, but the zombies behind followed one after another, they stepped on the ground and were still struggling to get up to continue to rush into the house.

Many of the zombies seemed to have flames burning on their clothes, but they didn't feel anything. The zombies crowded at the door of the restaurant, you push me, I squeeze you, they all want to get inside.

The stairs were blocked by Da Fei with some furniture, and these zombies would not be able to come up for a while. However, everyone was trapped on the roof of the building and couldn't go down the same way, so they had to find another way.

"Tear it down," Da Fei punched the iron wall of the shed, and found that the position of the force was concave in an instant, "This iron sheet is very thin, and the quality is very average." ”

"Okay," seeing Da Fei say this, everyone had no opinion.

The door of the tin hut was opened again, and everyone let the smell of it dissipate before entering the house and looking for something to match. A rack with things piled up was dragged out, and everyone dismantled it with all their hands, and then one person took a part of it and used it as a stick in his hand.

"Let's concentrate on smashing in one direction," Da Fei shook the wooden frame leg in his hand, "I shouted one, two, three, let's be together." ”

"One."

"Two."

"Three."

"Bang, bang!" The side where the shed was smashed was immediately dented in a large chunk.

"Push hard," Da Fei shouted, the green tendons on the back of his hand bulging, and the guy in his hand continued to slam violently against the iron wall.

The iron shed began to tilt after a while, and everyone was in high spirits when they saw that the situation had progressed, and the frustration of being forced upstairs after the previous failed operation had nowhere to vent, and they all began to desperately turn the wooden frame legs in their hands.

"Bang, bang," the iron boron has been tilted to a certain angle, and several of the brackets inside seem to have begun to break. Hearing a different sound from above, Da Fei knew that the shed was about to fall.

"Let me come," Da Fei stopped what he was doing, he motioned for everyone else to step back slightly, then took two steps back himself, and then rushed forward, flying up and kicking against the wall of the shed.

"Boom", the iron shed fell, Da Fei couldn't retract his strength, and the person was suddenly pressed inside by the fallen roof, Chen Bin and others hurriedly rushed over to pick up the debris and pulled him out.

Da Fei was helped up from the ground by everyone, he patted the ashes on his head with his hand, and then spat a few more mouthfuls.

"Damn, it's too hard......."

"It's not hurt, is it?" Chen Bin asked.

Da Fei checked his body and shook his head, "The clothes are thick, it's fine." ”

The tin shed collapsed on the ground, and the asbestos tiles that had been covered with it were also crumbling a lot. Da Fei stepped on the top of the pile of iron shelves, and then climbed the low wall in front of him, "You can climb over here." ”

As he spoke, he leaped forward, and the figure had disappeared on the other side of the low wall.

The others followed, but no one cared that there were still a few rotting corpses pressed in the iron sheet under their feet, and the smoke and dust raised from the ground had not yet fallen, and there was no one to be seen on this side of the low wall.

At the other end of the low wall is the roof of a nearby building, this roof is an old-fashioned sharp corner, and there is a drop of nearly two meters between its top and the top of the next low wall.

Da Fei and the others landed steadily on the pointed roof, stepping on the earthy red tiles under their feet, and everyone tried the load-bearing capacity of the roof here.

"It's okay," Da Fei said, and the others nodded. One side of the roof slope is tightly attached to the wall of the building next to it, so as long as the soles of your feet are strong, you don't have to worry about falling down.

Everyone turned to the other side of the roof, and the front suddenly became vacant, Chen Bin cautiously walked to the side and glanced down, and found that there was a vacant field underneath, and there were several cars parked in the field.

"I can't get over the front," Chen Bin said and said by holding down the call button on the walkie-talkie, "Xiao Sheng, help us check if there is a place to go nearby." ”

"Brother Bin, you can walk on the right hand, but the wall seems to be a little high," Chen Sheng's voice came from the walkie-talkie.

Chen Bin saw the drone flying overhead towards the west, and he looked there, "Let's go and have a look here." ”

Chen Bin said and climbed to the west, where the building was connected to this building, but the top was one floor higher.

The four of them came to the bottom of the wall and found that the wall was indeed "a bit high" as Chen Sheng said.

"I'm afraid it's more than three meters high," Qiao Xingyu looked at the upper edge of the wall in front of him with some worry.

"It's not a big problem," Chen Bin thought for a while and said into the walkie-talkie, "Xiao Sheng, is there any danger on the wall?" ”

"Wait a minute, I'll see." Chen Sheng said and continued to control the drone to fly up and observe, "On the other side of the wall is the balcony on the top floor of someone else's house, and no zombies were found on it. ”

"That's good," Chen Bin breathed a sigh of relief.

"The power is alarmed, I will fly the drone back to replace the battery first," Chen Sheng noticed the power displayed on the screen, and could only take the drone back for the time being.

"Okay, you can control the situation without man-machine, you don't need to ask us." Chen Bin said and began to observe the wall.

"Can you go up?" Qiao Xingyu asked with some concern.

"It should be possible," Chen Bin nodded, "Do you know about the escape wall?" ”

"Escape wall?" Qiao Xingyu was stunned for a moment, and then reacted, "But we seem to have fewer people." ”

"It doesn't matter, the wall is not very high," Chen Bin said and looked at Da Fei and Bian Ce, and saw that both of them looked puzzled, so he had to explain, "The escape wall is also called shipwreck escape, which refers to the fact that during World War II, when a merchant ship was hit by a shell from the Vikingman army on the rough sea, and the ship was about to sink, the lives of dozens of crew members were threatened. Only by relying on the strength of the team to climb over the 4-meter-high cabin can everyone have a chance to escape. ”

"There is a similar story in the history of the West Point Military Academy in the United States, the night before the graduation of a certain batch of cadets, the cadets of this batch carried out the last water patrol mission before leaving the school, because it was the last patrol, so the cadets did not drive seriously. Their patrol boat crashed into a cruise ship on the surface. It was late at night, and no one noticed it. The deck of the cruise ship was 4.2 meters high from their patrol boat, and there were no tools on the patrol boat to help them climb, but the crew was calm and escaped by climbing the deck by using a human ladder. ”
