Although Xiao Yao also told these mercenaries that the people who came to attack the factory today were very powerful, and like monsters, it was difficult for ordinary guns to damage them.

However, these mercenaries obviously didn't take Xiao Yao's warning too seriously.

Compared with Xiao Yao's alarmism, these mercenaries are more willing to believe in the weapons in their hands, and in their opinion, there is no one who cannot be killed with their weapons.

Li Yu knew the thoughts of these mercenaries, but he had nothing to do about it, so he could only mourn for them in his heart.

The enemy is already very strong, and these mercenaries are so careless, they will definitely suffer a big loss in the end.

Li Yu estimated that when the battle was over, it would be good if half of these mercenaries could survive.

Fortunately, these mercenaries and cannon fodder are similar, as long as they have money, they can continue to recruit at any time, and Li Yu will not feel distressed no matter how much he dies.

Everyone waited until about one o'clock in the morning, and the helicopter in the air finally sent a signal to Li Yu: "BOSS, forty degrees south-west, about ten miles away from the factory, there seems to be movement!"

"Keep probing and see if it's an enemy?"

Li Yi ordered solemnly.

The helicopter shot a searchlight in the air and flew slowly towards the southwest.

"Boom!"

At this moment, a loud noise suddenly sounded in the air, and a huge fireball suddenly exploded in the air.

"Not good!"

Li Yu's face couldn't help but change, and he saw that the location of the explosion was in the direction where the helicopter was.

"Prepare for battle!"

Li Yu hurriedly ordered the mercenaries in the factory.

His face was a little unpleasant, not only because of the loss of a Dragon Eagle helicopter just now, but also because of Ambrera's courage to come this time.

When they found out that they had been discovered by a helicopter, not only did they not have the slightest intention of retreating, but they brazenly took the lead.

It can be seen that they have a strong confidence in their own strength.

Seeing that their helicopter was killed by the other party so quickly, the mercenaries, who were originally a little unconcerned, also became solemn.

They also now realize that the enemy is stronger than they expected.

"Boom!"

The more than a dozen planes that were originally parked in the open space began to take off one after another after hearing Li Yu's order.

At this time, I can't care about continuing to hide.

If you wait until the enemy rushes to you, it's too late to think about flying.

After these planes took off, they all increased their altitude this time, for fear of being destroyed by the other side like the first helicopter.

Less than five minutes after the helicopter exploded, the factory gate was blown to pieces with a "bang", and a giant more than two tall appeared outside the door carrying a bazooka.

The giant bazooka rested on the giant's shoulder, as light as a toy.

And behind this giant, there were more than a dozen equally tall figures standing behind with various weapons.

Through the searchlight of the factory, you can clearly see the hideous faces of these people, and their eyes are full of bloodlust and murder.

"Biochemical Warriors!"

Li Yu's eyes narrowed, and he immediately recognized the identities of these more than ten people.

"Immediately concentrate maximum firepower and fire them all!"

Li Yu immediately shouted the order to all the mercenaries to open fire.

"Boom, boom!"

"Da Da Da, Da ......"

“……”

After hearing Li Yu's order, the guns in the entire factory suddenly rang out.

All the mercenaries fired at the dozen or so men who had pointed their weapons at the door.

They originally thought that under such an intensive attack, the more than ten people at the gate would definitely be bombarded soon, and there would not even be any scum left.

But the reality turned out to be so surprised that everyone's eyes almost fell out!

They saw that the more than a dozen people at the gate were not only not blown to pieces under their dense artillery bombardment, but walked into the factory step by step under the dense gunfire.

Although the clothes on their bodies were all shattered, there were indeed no wounds on the bodies of these biochemical warriors!

All the mercenaries who saw this scene were shocked and changed color.

Only then did they know what Xiao Yao meant when he told them that these people were monsters.

They seemed to ignore the force of the guns hitting them, and except for the occasional heavy artillery hit, they would take a slight step back, and other ordinary guns and artillery could not stop their progress at all.

"Such a powerful force, it really deserves to be a second-order biochemical warrior!"

Li Yu, who was protected by everyone at the back, was also very surprised.

He had seen the strength of an ordinary biochemical warrior when he was in Yanhuang before, when the biochemical warrior was strafed by a machine gun for more than ten minutes before he was completely killed.

But that time, ordinary biochemical warriors appeared, and these second-order biochemical warriors were completely incomparable in terms of strength!

Li Yu saw with his own eyes that after a second-order biochemical warrior was hit in the chest by a shell fired from a tank's main gun, his body only stagnated slightly, and then he continued to rush forward.

Not only are these second-order biochemical warriors more powerful and defensive, but they are also very agile.

It's just that because they were temporarily suppressed by the guns, they couldn't exert their speed for a while.

"What kind of monster is this!"

"Damn, why can't you die!"

“……”

As the attack continued, the mood of the already mercenaries began to collapse.

Although many of these mercenaries have also participated in wars and have blood on their hands, they are much stronger than ordinary people in their will to fight.

But now in the face of monsters like second-order biochemical warriors who can't be killed no matter how they fight, the performance of these mercenaries is actually not much stronger than ordinary people.

"Don't stop, keep attacking!"

Seeing that some mercenaries even began to give up the attack and wanted to turn around and flee, Li Yu's face couldn't help but change, and he hurriedly shouted through the communicator.

Li Yu knew very well that now he could only rely on his powerful firepower to temporarily suppress these second-order biochemical warriors, so that they could not exert their speed.

However, if the firepower is weakened, allowing these second-order biochemical warriors to exert their full speed, then it will be difficult to aim at them again.

And once they rush into the mercenaries and engage in a melee, it will definitely be a one-sided massacre.

It's a pity that many mercenaries are already frightened in the face of this incomprehensible existence, even if they hear Li Yu's shouting, they have no intention of stopping, and continue to turn around and flee.

"Damn it!"

Li Yu couldn't help but be angry in his heart, knowing that if these people fled, then the others would follow suit, and the entire formation would definitely collapse.
