After thinking about it secretly, Li Nan patted Pierce on the shoulder and said with a smile: "Your words remind me that although this is an underground building and there are no windows to climb, we can make holes in the floor!" ”

Pierce said blankly: "Even if we blow up holes in the floor, those flying birds and zombies will still rush over and attack after being alarmed?" ”

Hearing Pierce's words, Chris and Parker and the others all looked at him like idiots.

After the black girl Sheva gave Pierce a roll of the eyes, she said angrily, "Do you like to fight those zombies on the flat ground, or do you like to shoot them at will from a high position?" ”

"Oh! I understand. It finally dawned on Pierce.

Parker, who was holding a heavy machine gun, suggested: "We can take those iron cages apart and put them on the blasted floor slab when the time comes, so that the monsters can resist the monsters' attacks, and we can shoot comfortably." ”

This rough man would have such a proposal, which surprised Li Nan a little, and hurriedly praised: "Good idea! ”

Now that the countermeasures have been discussed, everyone takes the people to work separately, Chris directs the demoman to place explosives on the floor in the middle of the floor, and Parker leads the people to get some metal cages to dismantle them.

All the soldiers were loaded with guns and ammunition around the blasting point to prepare, and after a muffled sound, a large hole with a radius of two meters was blown out in the middle of the floor, and several soldiers waiting on the side hurriedly dragged the metal mesh over and covered the hole.

Such a big movement alarmed all the zombie birds in the layer below, and these monsters rushed to this cave one after another, wanting to kill the humans above.

Unfortunately, with a sturdy metal mesh in the way, their most powerful flying skills were useless, and the soldiers slowly aimed around the hole, and these zombie birds were killed in pieces like ordinary chickens and ducks.

Half an hour later, the tattered corpses of the Asuka zombies were piled up on the floor below, and when they heard that there was no movement below, the soldiers slowly stopped shooting.

"Go down and two teams to scout and lure the enemy, in case of danger, come back here immediately, we will cover your retreat!"

In the battle just now, due to the correct way of fighting, there were no casualties among the soldiers except for some bullets expended.

Along the way, Li Nan personally broke the steel ball mechanism, evaded the murder trap in the corridor, figured out a way to kill the invisible zombie, and personally killed the giant African zombie elephant, and in this battle just now, because of his correct way of fighting, there were no casualties among the soldiers except for the consumption of some bullets.

With such excellent command ability and strong combat effectiveness he showed, all the soldiers and members of the elite squad were already convinced of him, so although the task of detecting and luring the enemy was very dangerous, some soldiers did not hesitate to carry it out.

After reconnaissance, Li Nan found that these flying bird zombies were stupider than he expected, they did not hide and ambush, but all rushed to the entrance of the cave to attack and were killed, so there was no danger on this floor.

Since this method worked, and the bombs in the hands of the soldiers were enough, the whole team continued to use the combat routine of blowing up holes, erecting metal mesh, and then attracting monsters to kill.

After all kinds of accidents and several fierce life-and-death battles, there were still 112 of the 500 soldiers left at the time of departure, but relying on this method of killing the enemy, they actually achieved zero battle damage on the most difficult floors.

The 45th to 49th floors of the underground building are supposed to be used for raising various creatures.

Zombie land animals, birds, water creatures, reptiles, insects......

The last layer appeared is a group of zombie insects, these monsters are too small in size, and many insects can fly, so they almost brought huge damage to the team, if it weren't for Chris and Li Nan and others who quickly threw several incendiary bombs to restrain them, I'm afraid that these zombie insects would have drilled out of the mesh of the metal mesh.

After killing all the way, everyone couldn't remember how many monsters they had killed, and after eating and resting for a few hours again, seeing that there were still five floors of victory in sight, Li Nan ordered the Demoman to continue exploding.

Unfortunately, this time the battle plan failed, because after blowing up the reinforced concrete on the floor slab, it was covered with a thick layer of metal plates.

Li Nan, who did not believe in evil, asked the soldiers to blow up several other locations several times, and finally confirmed one thing, the fiftieth floor was completely built of special metal.

Since this road is impassable, and there is only the smallest five-story building left anyway, Li Nan decided to break through after discussing it with Chris and the others!

When he came to the entrance to the next floor, he found that the two alloy doors that should have been closed were actually wide open, this abnormal phenomenon made Li Nan a little suspicious, and hurriedly ordered everyone to stop and be on guard.

Li Nan was about to ask Quint to come forward to inspect when a loud laugh came from the PA device hidden in the wall.

"Hahaha, don't be afraid, there are no traps or traps here. Since you can afford to be here, come in for my wedding! ”

Li Nan didn't believe the enemy's nonsense, so he asked Quint to check it carefully, and after confirming that there were no traps, he led everyone into the fiftieth floor of this underground building.

The area of this floor is not large, and in the hall of more than 100 square meters, there are eight round tables covered with white tablecloths and neat tableware, and next to each round table are placed eight upright mahogany coffins.

Moving pictures of grass, flowers and trees, blue sky and white clouds appeared on the four walls and ceilings, and there was a long table also covered with white tablecloths in front of Li Nan and others, and a man and a woman sat behind them.

Li Nan took a few steps forward and said to the white-haired middle-aged man in a white suit, "Glenn? Glenn. Arias? ”

The white-haired man stood up and said with a smile: "You are the captain of the team this time, Mr. Li Nan, I'm Glenn, it's a pleasure to meet you." ”

Before Li Nan could continue to speak, Chris behind him suddenly took a few steps forward, looked at the beautiful girl sitting behind the long table, wearing a silver-white dress and combing her pretty short hair, and shouted in surprise: "Rebecca, is that you?" ”

When the short-haired girl Rebecca saw Chris, her face showed joy and she shouted eagerly: "Chris, you must be careful, it's dangerous here!" ”

"Huh!"

Before Rebecca could finish speaking, the metal door behind Li Nan and the others closed automatically, and Glenn shouted with a little madness: "Anyway, it won't be long before the world will be destroyed, since you are here, then don't go." ”
