There are four headquarters of the Skeleton Mercenary Regiment, and the first line of defense is said to start from two kilometers away from the castle, mainly wireless alarm devices and various mechanisms, this area is called the buffer zone. As soon as an intruder appears here, the headquarters guard of the Skeleton Mercenary Regiment will rush to the area as soon as possible to engage the enemy head-on.

If someone breaks through the first line of defense, they will find a sniper of the second line of defense within an area of 200 to 400 meters from the castle, and all the elite troops of the Skeleton Mercenary Regiment headquarters will participate in this sniping.

The third line of defense is the castle itself, where the firepower and traps are also the most tight, and it is called a fortress of battle, even if the regular army wants to break through here, it will be quite costly.

If someone really attacked the castle of the headquarters of the skeleton mercenary group, then only the last line of defense remained, which was the secret base owned by Wang Hai.

The security system of the secret base is self-contained, with special functions such as explosion-proof and shock-proof, plus there is enough food and water inside, and it can be called a shelter in a certain distance.

Since the establishment of the headquarters of the Skeleton Mercenary Regiment, there have indeed been many attacks, but each time the intruder has been dealt with in the buffer zone, and only last time a martial arts powerhouse like Sun Ling's mother broke through the third line of defense and entered the castle.

At this time, Wang Hai, Olivier, and Sayali were already standing in front of the supercomputer of the secret base, watching the surveillance video from various regions.

The battle was very fierce, the number of enemies was about 200 people, but the total number of the four squads of the headquarters escort team was only 40 people, although there was the help of the organs, but it was completely unable to stop the enemy's impact.

Carlo, who was the first to fight the enemy, had already been killed, and the last member of Team C had also died under the noses of Wang Hai and others, and the fourth sector had become a defensive hollow area.

For the first time, so many people attacked the headquarters of the Skeleton Mercenary Regiment, and they also broke through the buffer zone.

"Who are they?" Olivier asked in a low voice, his eyes full of anger.

Someone dared to attack the skeleton mercenary group, which was equivalent to someone reaching out to slap the tiger's butt, which completely angered Olivier.

"I don't know, I can only see that these people are professionally trained, but they don't look like regular troops." Andy said with a puzzled look on his face that he had been investigating since the beginning of the battle, but until now he had not found out the identity of the enemy.

"Could it be another mercenary group?" Sayali asked.

Olivier shook his head and said, "Impossible. ”

Of course, it can't be other mercenary groups, you must know that the skeleton mercenary group has a loud name in the mercenary world, and it has already been among the top mercenary groups in the world, and there are almost no people who dare to attack the headquarters of the skeleton mercenary group so blatantly.

Wang Hai carefully observed the surveillance screen, the invasion did not look like a regular army or mercenary group, they looked like they were acting very planned, but it was not difficult to find that these people did not have too deep cooperation, and they were basically fighting on their own. However, these people are definitely masters of the masters, they know better than ordinary soldiers how to make a person die, and they generally do not look at the target after hitting it, and they are very confident.

"Killer!" Wang Hai spat out two words heavily.

Killer!

Olivier, Andy, and Sayali looked at Wang Hai together, and Olivier said with a puzzled expression: "Are you sure they are really killers?" ”

Wang Hai nodded very affirmatively, he was very sure, because he used to be a killer too.

"But haven't all the killers in Paris been driven out by us, and where did they come from?" Andy asked, puzzled.

"I don't know." Wang Hai shook his head lightly, and then spoke, "The lowest level of these people is also a Y-level killer. ”

It's not been a day or two to fight with the killer group, and Olivier and Andy are also very clear about the level of the killer, the Y-level killer can be said to be the top master in the killer group, no wonder the combat effectiveness is so amazing.

"Look!" Sayali suddenly exclaimed, pointing at one of the images.

Everyone looked over, only to see that a killer on the screen had avoided the attack of a skeleton mercenary, and smashed the mercenary's head with a wave of his hand.

Warrior!

Everyone was taken aback, there were warriors among the invaders, and it was not surprising that they had broken through the first line of defense.

"Andy, raise the danger level to the maximum!" Wang Hai gave the order, and then rushed out without looking back.

Since it was the killer who came, and there were warriors among them, it was impossible to stop the brothers outside, and Wang Hai had to go out to fight in person.

The one who suddenly appeared to attack the headquarters of the Skeleton Mercenary Group this time was indeed the elite killers sent by the killer group, including one hundred Y-level killers, fifty Z-level killers, and the rest were all martial artists.

These warriors are also killers in the killer group, and they have moved away from the alphabetical hierarchy of killers and have become a special kind of killer, called high-level killers.

Among these fifty high-level killers, there were twenty first-order samurai, ten second-order samurai, eight third-order samurai, five fourth-order samurai, three fifth-order samurai, two first-order martial artists, one second-order martial artist, and one fifth-order martial artist.

After all, in proportion to the population, martial artists are as rare as pandas compared to ordinary people, and there are even fewer high-level martial artists, and it can be said that the killer group can send so many martial artists at one time, and it can be said that it is bloody, and it vows to pay the price for what the skeleton mercenary group has done.

Wang Hai was hiding at the top of a tower in the castle, holding a large sniper rifle in his hand, and had just reloaded his bullets and was about to shoot when he saw footsteps behind him, and instinctively looked back and found Sayali floating to his side.

"I think you might need help." Sayali said.

Wang Hai smiled slightly, handed over the infrared sight beside him and said, "You help me find out the location of the martial artist in the enemy, and it is best to tell me the distance." ”

"Okay." Sayali replied softly, taking the binoculars and looking for them. Her eyes were like a sophisticated radar scanner, and she could tell who the martial artists were at a glance, and those martial artists hidden in the ordinary killers were quickly found by her one by one and reported to Wang Hai.

"At three o'clock, five hundred and sixty meters away."

"Smack!"

Whenever Sayali reported the precise location of a warrior, Wang Hai would quickly lock on to the opponent and pull the trigger.

Warriors are indeed several times stronger than ordinary people, but most of the low-level warriors who appear here are samurai-level warriors, under the perfect combination of Wang Hai, a sniper genius, and the powerful power of a large sniper rifle, plus the cover of the night, it is difficult to escape the fate of being sniped even if the enemy is aware of it.

Although hidden in the dark, the sound of the large sniper rifle can easily reveal the location, and Wang Hai will take Sayali to change the sniper position after sniping two warriors every time he snipes to avoid being counter-sniped by the enemy.

"Huh." After another change of position, Sayali let out a soft cry as soon as she picked up her binoculars.

"What's wrong?" Wang Hai turned his head and asked.

"It's Olivier, he's in the direction of eleven o'clock, three hundred and fifty meters away." Sayali preached.

At this time, the enemy had already arrived at the location of the second line of defense of the Skeleton Mercenary Regiment, and fought with the elite troops of the Bone Marrow Mercenary Regiment Headquarters.

Machine guns, artillery, armored tanks, etc., the skeleton mercenary group is well-equipped and has fast firepower, which blocked the killers here for a while.

Wang Hai looked through the scope, and sure enough, he saw Olivier's figure at a distance of three hundred and fifty meters at eleven o'clock.

It was Olivier's style to take the lead, and someone took the initiative to find the door, which made Olivier very angry, so she rushed out and directly confronted the enemy.

Fighting Olivier was a third-order samurai who wielded a long whip.

As the leader of the Skeleton Mercenary Regiment, Olivier's portrait has long been imprinted in the minds of every intruder, making her the first target.

The enemy originally thought that Olivier would hide in the skeleton mercenary group, and in order to kill Olivier, he had to break through all the defenses, but he did not expect Olivier to rush to the front.

The third-order samurai recognized Olivier and couldn't help but be overjoyed, if he could kill Olivier, he would get a lot of rewards if he went back.

"Little girl, if you are willing to accompany Lao Tzu for two days, then Lao Tzu will make your death a little more comfortable." The third-order samurai thought that Olivier was still the same as before, and thought that with his third-order samurai cultivation, he could easily defeat Olivier, so he said such obscene words.

Olivier didn't bother to talk nonsense with the other party, so he slashed directly with a knife.

The third-order warrior hurriedly swung his whip to block Olivier, but found that his proud whip technique could not touch Olivier's figure at all, and then he knew that Olivier's martial arts cultivation was far above him.

Olivier is already a fifth-order peak martial artist, coupled with his perception in the battle with the second-order martial king Mike and the cultivation in the past two days, his martial arts perception has been further improved, and he should break through to become a first-order martial artist in the near future. In the face of a third-order martial artist, Olivier was still quite easy to fight, plus he was holding a treasure knife in his hand, and the two "brushes" split the opponent into three pieces.

A third-order warrior didn't even have time to scream under Olivier's beheading, and after his death, he was afraid that he regretted his previous teasing words very much.

After slaying a warrior, Olivier's confidence increased even more, and he charged forward again with the winged Zen sword in his hand.

"Olivier, come back quickly!" Wang Hai hurriedly called out through the communicator.

Olivier didn't make it back, and she was entangled by two enemies who were also fifth-order warriors.
