Based on his own judgment, Lin Rui brought a small group of mercenaries to the southeast of the factory. The battle here has been very intense.

The attackers have multiple armed vehicles and are forcibly assaulting the area. The recoilless gun on the vehicle has blown up the fence of this side of the factory. Construction waste such as concrete blocks and steel bars were scattered everywhere.

A small team deployed here before. Relying on a fragmented wall, dealing with powerful enemies.

The timely support of Lin Rui and others also gave them a chance to breathe.

"Big Dog, how is the situation?" Lin Rui asked loudly.

In charge of this team is a mercenary code-named Big Dog. Originally in Lincoln's B group, he was recently transferred to A group. At this time, he was already ashamed, and one arm was still bleeding.

"They have too many people and armed vehicles. We just used a rocket launcher to kill one of them. The brothers were still suppressed here. Their firepower is too fierce, and I don't think it will last long here." The big dog gasped.

"I can't go on like this. Those cars must be killed. Those vehicle-mounted machine guns pose too much threat to us." Lin Rui looked up and looked at the situation, then quickly lowered.

The bullets of the vehicle-mounted machine gun flew over their heads.

"Is there a bazooka?" Lin Rui asked, turning his head.

"There are not many, there are two more." Big Dog replied.

This is what they are equipped with is the French army standard rocket launcher. Apilas 112mm rocket launcher, the French called it an infantry light anti-armor weapon system.

This kind of thing is powerful, accurate, and fast in battle. The disadvantage is that the launch features are obvious, the noise, tail flames and smoke are large, and it cannot be launched in a limited space, and it is not suitable for combat in urban areas.

Although they knew this time. The secret society militants may attack the laboratory, but they did not expect that the other party would drive an armored vehicle to storm.

So it was not equipped with this type of anti-armor weapon at the beginning. The reason for these bazookas is that Lin Rui specifically asked Mr. K to deal with the emergency. I didn't expect to actually use it.

However, with just a few rocket launchers, the opponent has at least seven or eight armed vehicles for combat. Obviously not enough to cope with the current situation.

But now he couldn't take care of that much. Lin Rui picked up one of the bazookas and gestured to the big dog, "Cover me."

The big dog immediately ordered and concentrated firepower to cover Lin Rui. The mercenaries raised their weapons and fired.

With this momentum, Lin Rui trot all the way with the rocket launcher and rushed out of the bunker. Crouching on one side of the wall, he took aim at an armed vehicle of the opponent.

"Boom!" Apilas' 112mm rocket launcher ejected a huge tail flame, and the rocket accurately hit the vehicle. A more dazzling light burst out.

The tail flame of the rocket launcher also exposed Lin Rui's location. Lin Rui hardly hesitated after launching, throwing the rocket launcher and running.

Before he ran very far, his original location was covered by dense bullet rain. Randomly is a recoilless cannonball.

Lin Rui threw himself under the ruins, his chest and abdomen were dulled by the construction waste on the ground, and his head and back were also covered with flying debris and sand.

He raised his head, shaking off the sand from his body. A fish jumped back into the bunker. "Can't hold it, let's go! Tell the brethren, retreat to the inside of the factory."

"Retreat! Retreat to the inside of the factory!" The big dog yelled. Lin Rui took his small team and withdrew back to the factory with the big dog people.

Colleague Lin Rui ordered a mercenary to help him pass the order to make all the mercenaries retreat.

The perimeter defense of the plant is about to be breached if other troops do not retreat in time. There will be a danger of being divided and surrounded by the enemy.

Several squads that were organizing resistance all received the order and began to retreat under the cover of firepower, retreating to the position of the factory.

Lin Rui observed the surroundings. Although these workshops were built to cover the underground laboratory, they were all reinforced concrete buildings and their structures were quite strong.

This should buy them some time.

Just as they were organizing to rebuild the defense line, Jonathan hurriedly rushed with people.

"How's the situation?" Jonathan asked in a low voice after arriving.

"The perimeter is lost, and the enemy has entered the factory area. We have to use these production workshops to organize another wave of defense. It is not necessary to expose the laboratory to the opponent." Lin Rui wiped the sweat from his head.

"The plant here is quite sturdy and should be able to hold for a period of time. The swarm communication jamming system will not last long. We only need to hold on for an hour." Kuaima and Eric came back safely.

"The sniper team will come with me. I need someone to occupy the upper window of the workshop." Eric arranged the task loudly.

On the other side, Yelena also took the remaining two sniper team members and arranged the defense on the other side.

"Hang the two pieces of machinery over there and block the door." Sergey was instructing the other mercenaries to use the crane in the factory building to pile up several pieces of machinery at the door. To block the entrance of the workshop.

"The windows over there are also blocked with equipment. Put the machine gun to that position. Hurry up, everyone will move." Lin Rui shouted loudly.

The gunshots had entered the factory area, and Lin Rui and his men stood firmly in the workshops behind. This is the entrance to the underground laboratory.

Jonathan held an automatic rifle and shook his head. "After I was discharged from the army, it was the first time I encountered such a big battle. These lunatics actually launched an offensive with great fanfare. This is a Level 4 Biosafety Laboratory. This It's crazy."

"They are not crazy. In fact, they may know the conditions of the laboratory very well. They know that no matter how damaged the ground buildings are, they cannot affect the safety of the underground laboratory.

Otherwise do you think they dare to do this? This group of people is far more powerful than you think. "Lin Rui said sternly.

"So what? It is difficult for them to break through here. And if it is not possible, we can hide in the underground facilities. The entrance there is narrow, easy to defend and difficult to attack.

Just the door outside the underground laboratory, they don't want to easily break through. "Jonathan gritted his teeth.

"Don't have this idea, because once we retreat to the underground laboratory, we will never retreat. If they attacked from the vent with poisonous gas, we would all die inside.

After all, the fresh air system of underground facilities must exchange air through the outside.

Once we are stuck inside the laboratory, that is the worst result. So we have to delay them as much as possible and buy time. Lin Rui said in a low voice.
