There was a sound effect in the metal passageway, and upon hearing this strange sound, all the soldiers and squad members on the march knew that danger was present.

This time, no one resisted Li Nan's order, and all of them ran as fast as they could, but this spiral-shaped passage restricted everyone's movements, and soon the rumbling sound of impact and the screams of soldiers before death were faintly heard from behind, and they were getting closer and closer.

After hearing this sound, and then connecting with this hamster-like structure, Li Nan, Chris and the others had already guessed what was chasing behind.

Their guess was right, the thing that was constantly accelerating and chasing was a solid steel ball with a diameter of more than three meters, and its own weight plus the speed of rolling, this huge iron ball had an incomprehensible lethality in this spiral-shaped passage.

Li Nan who was running calculated that according to the current running speed of everyone, the members of their elite team could not run faster than what was behind, and soon everyone would be caught up and killed, and now they had to find a way to solve this crisis.

After thinking for a while, Li Nan took off the electromagnetic gun he was carrying and the heavy backpack full of ammunition and supplies, and after throwing it to Du Xing and another armor guard, he said to the others very quickly: "You run first, I'll deal with the things chasing behind!" ”

When Chris saw Li Nan's actions, he hurriedly persuaded: "Li, I know what you want to do, but what you can't do, no one can do!" ”

"There's no time to explain, run, I'll get rid of it!" Li Nan, who dropped a sentence, did not advance but retreated, and met the steel ball that was chasing behind him.

Li Nan's plan was simple, but it was also very dangerous, he wanted to destroy the terrible steel ball at close range.

Bombs and the like can't be used in this metal tunnel, otherwise the shock wave generated after the explosion will bring severe damage to everyone, and Li Nan doesn't have a high-powered bomb in his hand that can shatter a solid steel ball with a diameter of three meters.

Looking at the huge steel ball that was getting closer and closer behind him, Li Nan tried his best to adjust his running speed to be slightly faster than the steel ball, and then he took out the handles of the two beam sabers from his combat vest, and after pressing the switch, two indestructible light knives immediately appeared in his hands.

Li Nan, who was running forward, turned around and quickly swung the beam saber and slashed a few times when the steel ball approached him, and then continued to accelerate and run forward.

If ordinary people did this, even a top fighter like Chris, who had experienced countless battles and crises, would be crushed into pulp by the accelerating steel ball.

Although Li Nan has been strengthened by the system to have the speed of a cat, his speed and reflexes are twice as strong as ordinary people, but what he is doing now is too dangerous, and the steel ball that is chasing closely behind him seems to hit him at any time.

In order to survive, Li Nan can only stimulate his full potential and run desperately.

The Beam Saber, an advanced high-tech weapon in the world, lives up to its name, and it really has the effect of sharpening iron like clay, and large pieces of steel are easily cut off.

Li Nan, who maintained a slight speed faster than the steel ball, kept swinging his knife and speeding up, and the round blood-stained steel ball that originally had a huge impact force was slowly cut into an irregular shape by him.

As time passed, the oversized steel ball was accurately cut into a cube by Li Nan's knife, and its rolling speed gradually slowed down, and when it was close to the exit, this terrible thing finally stopped.

Li Nan, who came out of the passage, was soaked in sweat, looking like he had just taken a bath, this kind of game of life and death was too exciting, he turned off the light knife switch in his hand, and sat directly on the ground gasping for breath.

The soldiers and members of the elite squad present all knew Li Nan's desperate actions in the back at this time, and they also knew that they were standing here alive now, not being crushed into pulp, which was completely due to the new Asian captain.

Parker, the bearded man who didn't play with Li Nan, took out a bottle of water from his backpack, unscrewed it and handed it to Li Nan's mouth, and said with some embarrassment: "Captain, drink some water." ”

"Huh." Li Nan took the water with a pant breath, and teased with a smile: "Why, you can afford to look down on me now, a coward?" ”

Parker said sincerely, "I'm sorry! I apologize for what I said before, you have proved with your actions that you are not a coward, but a good man full of cowardice! ”

"Bang Bang Bang ......"

Looking at the reconciled Li Nan and Parker, Chris applauded with a smile, and then the other team members and soldiers also applauded, and they sincerely expressed their gratitude and admiration for Li Nan who saved them.

Sheva, a black girl from Africa, is as unruly as a female leopard on the grassland, she originally looked down on Li Nan like Parker, but what Li Nan did did conquer her, at this time the girl also took a clean towel from her backpack, came to Li Nan and gently wiped the sweat on his face for him.

Li Nan enjoyed the treatment of a hero, and after five or six minutes, the last group of soldiers also pushed out the square steel block that blocked the way.

Because they entered behind Li Nan and the others, more than 20 people in the team were crushed to death by the steel ball.

After everyone gathered on the first floor, Li Nan stood up and counted the number of people.

Of the original 500 soldiers, 260 of them were lost in the air raid of zombie flying insects. Li Nan left twenty soldiers to guard the entrance, and then in the spiral passage, more than twenty more soldiers died, so now there were less than two hundred soldiers left.

Everyone had been informed of the danger of this mission before setting off, and they were all mentally prepared, but everyone didn't expect that they had already lost nearly three hundred people just after reaching the first floor of the underground building.

At this time, it is superfluous to say anything, and completing the task as soon as possible and going back alive is the right way.

Li Nan stood up and sent a team of eight ten-man people to explore this level, looking for a way to the next level.

Taking advantage of the gap in the soldiers' search, Li Nan led the team members to the corridor like a Go board.

Looking around, the corridor is lined with transparent glass on both sides of the office, and in each room there are dozens of light gray desks and chairs, with computers on the desks and filing cabinets and filing cabinets on the walls.

Li Nan pointed to the monitor on the desk in his office that was still lit and said to Quint, "Check the computer to see if there is a detailed map of this underground structure." ”

Quint studied the computer under the protection of several people, and Li Nan came to an office at random, sat on the office chair and looked around, involuntarily remembering his life in his previous life.

At that time, Li Nan worked in a similar environment, working overtime every day to make money, living a numb and boring life, but he didn't expect to travel to the Song Dynasty after his accidental death, and later discovered the system on the ring, and lived this life full of excitement and danger.

All this makes Li Nan feel like Zhuang Gong dreams of butterflies, but he doesn't know whether it was a dream in his previous life or a dream now, and what kind of life he prefers.

"Captain, there's a discovery!"

A voice over the walkie-talkie interrupted Li Nan's thoughts, and the team in charge of reconnaissance found the stairs and elevators of the underground building.
