"Don't tell Lao Tzu about it!" Lao Mo rudely interrupted Xiao Song's report, "You kid count Lao Tzu clearly, how many zombies are there on the fourth floor?" ”

"Okay, right away!" Xiao Song knew that the situation was urgent and knew Lao Mo's temperament, but Xiao Song himself was notoriously good-tempered, and he didn't care about Lao Mo's attitude towards him, so he quickly replied, "There are thirty-eight zombies on the fourth floor." ”

"Thirty-eight, not a lot!" Ding Xiangling thought for a while.

"Shall we go up?" Ben, the white man, asked.

"Of course we have to go, otherwise what are we doing here?" Lu Lidao.

Every time they go on a mission, danger is bound to exist, it is impossible to do nothing because they are afraid of danger, they need to survive in the zombie group of the last days, and it is impossible to talk about what is safe and what is smooth.

"Everyone, the mufflers on the guns are installed, right?" Lu Li asked.

"No problem!" The crowd replied after careful examination.

"Okay, let's go up, we must be light when passing by the second floor, and try not to alarm the zombies on the floors below the fourth floor." Lu Li arranged.

"Komatsu, order a helicopter to start, stand by, and take off at any time!" Lu Li continued.

"Yes, arrange it right away!" Komatsu's voice came from the communicator.

Although the cost of using a helicopter is very high, and it also means abandoning the motor vehicle driven by several people, for the safety of everyone, if they really can't get out of the stairs and drive back to the base, then they can only use the helicopter to take them back to the base.

Lu Li and the others got ready, then slowed down and moved upstairs.

After several people entered the stairwell, Lu Li motioned to the last black man to close the door of the stairwell on the first floor, but it was not locked.

The door is closed in order to block the possible passage of the zombies downstairs to a certain extent, because the zombies do not have normal human intelligence, they only know how to chase prey from the path, but they do not know how to open the door and other basic human behaviors, close the door of the stairwell, the zombies do not know where to go upstairs, and do not lock the door, so that Lu Li and others will not be blocked by the door when they retreat in the end, delaying their time to survive.

When we arrived at the stairwell connecting the first and second floors, everyone's hearts were in their throats.

Lu Li motioned for everyone to stop and gestured.

Ben and the black man understood, and each stood in his own position, pointing his gun downstairs; And Lao Mo and Xiao Qiu quietly followed behind Lu Li and Ding Xiangling, and moved upstairs with the two.

Lu Li and Ding Xiangling walked to the staircase on the second floor, and sure enough, the stairwell door on the second floor was closed, but it was not locked, and the door could be opened as long as both sides were gently pushed or pulled.

Lao Mo and Xiao Qiu bypassed behind Lu Li and aimed their guns upstairs.

Lu Li and Ding Xiangling stood by the door.

Ding Xiangling pulled out a piece of nylon thread from the cuff of his coat, snapped it, and then stepped forward and gently tied the nylon thread to the handle of the door.

After winding around several times, confirming that the door was tied to death, and the door of the stairwell could not be opened easily, Lu Li motioned to everyone to continue upstairs.

A few people walked lightly.

On the second floor, where there is a potential crisis, everyone has passed without danger.

Komatsu and the others, who were staring at the monitoring in the dispatch room of the stronghold, also breathed a sigh of relief at this moment.

On the third floor, there was no problem either, and several people quickly moved to the fourth floor.

Standing in the stairwell on the fourth floor, the stairwell door on the fourth floor is also closed.

It's just that Lu Li and the others didn't dare to open it easily, everyone knew that there were zombies on the fourth floor, and no one could guarantee that if the door of this stairwell was opened, they would not directly face the zombies.

"Komatsu, mobilize the drone, probe the entire fourth floor, and transmit the situation to us." Lu Li commanded.

"Yes!" In the dispatch room, Komatsu personally operated the drone and began to fly on the fourth floor.

"Brother Lu, the picture has been transmitted." Xiao Qiu moved to Lu Li's side and lifted the picture from the mobile phone video tied in his hand to Lu Li's eyes.

"There are no zombies at the entrance of the building," Ding Xiangling also looked at the electronic screen in Xiao Qiu's hand, "But if you want to go to the mall, you will inevitably have to meet the zombies." Ding Xiang Lingdao.

"Komatsu, continue to inspect and see if there are other stairwell entrances and exits on the fourth floor, there will not be only one stairwell in a commercial building." Off-the-road arrangement.

"Yes, investigating!" Komatsu instructed the others in the dispatch room to control other drone aircraft to fly on the fourth floor.

"Boss, there are four safe passages on each floor, at the four corners of each floor, you are now in the southeast corner of this floor, and there are also stairwell entrances and exits in the other three directions, after you finish picking up supplies in the mall, I will arrange a safer retreat route for you according to the specific situation." Komatsu's voice came.

"Good!" After Lu Li received Komatsu's message, he motioned to everyone and started to act.

Ben and the black man slowly opened the door to the stairwell on the fourth floor.

Lao Mo and Xiao Qiu's guns were always aimed behind everyone, up and down, guarding against the zombies that might rush from behind.

And Lu Li and Ding Xiangling's guns were pointed in front of them, staring at the door of the stairwell that slowly opened.

The door was slowly opened, and as Komatsu reported, there was no zombie activity in front of everyone, and it was empty.

Lu Li raised his hand, made a gesture, and motioned for everyone to go in.

Six people formed a battle formation, following Komatsu's instructions, and arrived at their target mall.

"Stop!" Komatsu's voice sounded in the Bluetooth headset in everyone's ears.

Everyone had a tacit understanding, and they stopped and squatted behind a load-bearing wall, using the load-bearing wall as a cover.

"Boss, wait a minute, turn right, it's the zombie group on the fourth floor, and behind the zombie group, is the shopping mall." Komatsu stared at the footage transmitted by the drone.

"Xiao Qiu!" Lu Li waved his hand and motioned for Xiao Qiu to come over.

Xiao Qiu came over with his mobile phone and held the screen in front of Lu Li's eyes.

Lu Li looked at the swaying zombies on the screen and took a deep breath.

"Boss......" Xiao Qiu whispered, suppressing his voice.

Lu Li signaled silence.

He waved back, and everyone understood, raised the various rifles in his hand, and checked the chamber.

Seeing that everyone was ready, Lu Li was the first to stand up and stepped forward.

In the zombie group of the last days, in a small-scale battle, everyone didn't dare to shout, everyone bit their lips tightly, didn't dare to make a sound, just pulled the trigger, added a muffler rifle in their hands, and killed the zombies that roared and rushed in front of them.

Lu Li and the others were worried that although the six of them could try not to make a sound during the battle, the movement of this small group of zombies was now extremely clear in this empty and quiet building, and it was estimated that the zombies in the entire building had sensed it, and they might be rushing to find a path to approach them.
