The sudden appearance of several construction vehicles disrupted the office building's defense.

When the guards were stationed here before, they deployed a company with a total of more than a hundred people. Once an enemy was encountered, this place was a powerful military fortress. Both the defense force and the firepower configuration were strictly calculated.

According to the original design report, this fortress can withstand at least ten times the enemy's attack under full firepower.

However, Ning Zhe and Lu's people together only have more than ten people. It is simply difficult to achieve all-round defense.

Several rockets and bombs originally on the fourth floor were in a state of emergency after they hit the courtyard. People on the third floor received the news and began to send people to deliver ammunition upstairs.

In just a few seconds, the loader outside the yard rushed to the outside of the factory, the shovel fell, and hit the yard wall.

"Boom!"

With a muffled sound, the red brick courtyard wall collapsed, and then the forklift shovel fell, pushing the rubble on the ground and rushing into the courtyard.

The access road opened, and several vehicles from behind rushed into the courtyard. An excavator raised its hydraulic arm, approached the office building, and smashed the shovel toward the second-floor window.

"Bang!"

The shovel of the excavator hit the curtain wall glass, leaving a white mark. Seeing this, the driver in the car controlled the direction and prepared to make up for it.

"Da da da!"

Before the driver could take action, a gun barrel poked out of the shooting hole on the first floor and began firing at the excavator's cockpit. The driver was shot several times and fell down.

At this time, the crusher from behind also drove into the courtyard, and the breaker hammer on the arm was pressed down and aimed at the curtain wall on the first floor.

"Dang Dang Dang!"

Under the continuous impact of the breaker hammer, spider web patterns began to appear on the glass.

"Back away! Get out of the window!" Hu Lang, who was inside the house, saw this scene and shouted into the headset: "Bazooka! Blow up the engineering vehicles outside!"

The young man on the fourth floor tried the rocket tube and gritted his teeth: "No! This car is in my blind spot! I can't move it!"

Hu Lang heard the response and shouted to the person behind him: "Bazooka!"

The person on guard heard this and quickly responded: "The first floor is not high enough! It is not equipped with a rocket launcher!"

"Wow!"

Within a few seconds, the curtain wall glass of the exterior wall, which could withstand the bombardment of rifle grenades, exploded under the pressure of the breaker hammer.

"Da da da!"

Upon seeing this, Hu Lang pointed his gun outside and started shooting continuously.

The driver of the breaker heard the sound of bullets hitting the car body, controlled the arm to block the shooting angle in the room, pushed the door and jumped under the car, and at the same time shouted: "The passage on the first floor is open!"

Shen Kang waited for a long time and found that there were no rockets or shells bombing the car downstairs. He made an instant decision: "The downstairs should be their blind spot. Go into the yard and close to the first floor! Prepare to break in from the first floor!"

Fast!"

"Hula la!"

Others around the courtyard wall heard the order and jumped over the wall, preparing to charge.

From the window on the second floor, Ning Zhe saw a figure flashing in the smoke and pulled the trigger directly: "They are ready to charge! Fire to suppress them!"

"Da da da!"

"Tu tu tu tu!"

"...!"

As soon as the people from the Black Horse Company moved, gunfire on all floors was fully opened. Gunfire flashed from all directions in the office building. A group of people who rushed into the courtyard were covered in a hail of bullets and fell instantly.

At the courtyard wall, a young man who was just about to charge heard the screams coming from the smoke, and immediately retracted, breathing rapidly, he said: "Brother, we can't go on like this, their firepower is too strong, even if we rush over, It’s also difficult to get into the building!”

"Withdraw!" Shen Kang originally wanted to seize the opportunity to launch a surprise attack, but faced with the huge casualties, he became extremely irritable at this moment. He picked up the phone and prepared to ask Meng Fan about backup, but the call hadn't been made yet. A number was called to him first.

Shen Kang looked at the unfamiliar number and pressed answer: "Hello?"

The other party said straight to the point: "I am Mr. Qu's bodyguard Zhang Yuan! I have arrived at Dongcheng Industrial Zone!"

When Shen Kang heard that the other party was someone close to Qu Xiangran, his eyes suddenly lit up: "What weapons did you bring?"

"Two heavy armored vehicles, as well as a batch of rocket launchers and explosives!"

"Finally some useful equipment! How long will it take for you to arrive?"

"Three minutes!"

"Okay!" Shen Kang agreed, and then ordered to the young man beside him: "Let all our people withdraw from the yard, backup is coming!"

…

After the attack and defense of both sides, most of the smoke bombs thrown into the courtyard have stopped emitting smoke, and the smoke density has also become much lighter.

On the top floor of the office building, the sniper found that the other party's people were running outside, and he breathed a sigh of relief: "Notify downstairs that the other party's people have retreated!"

On the first floor, Hu Lang heard the shouts upstairs, glanced at a broken window, squinted his eyes and said, "The situation is not right! They spent so much effort, but they suddenly stopped attacking, which means they must have found someone." In order to reduce casualties, if nothing else happens, backup should be arriving! How long will it take for our backup to arrive? "

Guo Shu, who was on the side, put down the satellite phone and replied: "I just contacted them. Several of our action teams have gathered together, but on the only way, they encountered a large number of test subjects, and they are currently taking a detour to come here. Be there within ten minutes at the latest!”

"Notify all floors to be prepared to hold out for twenty minutes. Once backup arrives, we will immediately organize a breakout!"

…

Black Horse Company's second round of assault failed, causing the scene to fall into a brief calm. The smoke in the courtyard gradually dissipated, revealing corpses on the ground and the still burning car wreckage in front of everyone's eyes.

About two minutes later, two heavy armored vehicles appeared at a distant street intersection.

Zhang Hao, who was on the top floor, saw this scene and quickly picked up a rocket launcher and moved towards the shooting hole on one side: "An enemy armored vehicle appears in the northwest!"

"Enemy vehicles appear in the southeast!"

"Enemy troops appear in the northeast!"

"...!"

At the same time that Zhang Hao discovered the armored vehicle, several backup units from Black Horse Company rushed to the scene and surrounded him from all directions.

"call out!"

When the armored vehicle approached, Zhang Hao directly fired the rocket.

"boom!"

The rockets and shells accurately hit the armored vehicle, but the explosion failed to stop its progress.

"Hang bang bang!"

The armored vehicle was attacked, and the large-caliber cannon on the vehicle immediately launched a counterattack. The shells continuously bombarded the wall, and the glass of the curtain wall began to shatter and fall off.
Chapter completed!
