C76

The firearms of the two mercenaries were just ordinary assault rifles, they simply could not penetrate the bunker.

Looking at Shen Feng who was hiding behind his concealment, he quickly set up his sniper rifle.

"Bam!"

Another armor piercing bullet flew out from the muzzle and killed a mercenary through the cover.

Out of the six elite mercenaries, only one was left!

The remaining mercenary felt like he was going to collapse because he had never seen such a powerful soldier. Just one move and he had completely annihilated the combat team he was part of.

"Flee!" This was the last thought the mercenary had.

The mercenary took the chance when Shen Feng wasn't paying attention and immediately crashed into the door, escaping towards the underground center of the research facility with his fastest speed.

In the battlefield, if they met on a narrow path, it was equal to losing half their battle of cowardice. Not to mention that he had already collapsed.

Before the mercenary could get within twenty meters of him, a bullet flew from the side, striking him in the temple and flying out from the other side.

Under the effect of inertia, the mercenary's body charged forward two steps before falling to the ground.

A six man team was annihilated by Shen Feng in less than a minute.

The mission wasn't completed yet, so Shen Feng didn't stop his footsteps and continued to think about where he was going to go underground …

In the underground center, a Bald Black was commanding.

"Boss, we can't contact the first group." A white man said in panic.

"Chief, we can't contact the third and fourth groups either."

He naturally knew what it meant to be unable to contact them. He didn't expect that in such a short time, they had already lost nearly half of their fighting strength.

"The scattered teams, come back quickly. We have hostages and they are safe for now. We can negotiate with them!" The leading Bald Black said in a deep voice to his headphones.

"Yes sir!" An answer came through the headset.

Shen Feng annihilated another group along the way. In front of him was the underground center of the research facility that held the hostages.

At this time, the sound of hurried footsteps came from the side of his ear. Shen Feng's figure flashed, and he hid to the side.

There were about a dozen of them, two combat teams.

They were all mercenaries brought back from different places in the research facility, but these mercenaries did not know that Shen Feng had already infiltrated in front of them.

Just as the mercenaries were running forward, three or four round objects rolled over from the front.

"Hand grenade!" The frontmost mercenary shouted. Everyone quickly looked for cover.

However, Shen Feng had already calculated the time, when they discovered the grenade, it was already too late.

"Boom …" A few grenades exploded in the middle of the crowd. The mercenaries closest to them were blown into pieces and their blood and flesh were splattered all over the place. They were wailing in pain nonstop.

Shen Feng did not give them any chances, and directly rushed out while holding onto his assault rifle.

These mercenaries were blown up badly by the hand grenades, and more than half of them were killed. In less than half a minute, all of the mercenaries were killed by Shen Feng, leaving behind only around 10 mercenaries in the middle of the ground.

Because this place was so close to the underground center, the people inside could clearly hear the sounds of battle.

However, the gunshots did not last for more than half a minute, and the whole research facility quieted down.

"Boss, it seems like we're the only ones left." A white brute with cold sweat dripping down his forehead shook the gun in his hand and said.

The leading Bald Black scolded loudly: "I'm not f * cking deaf!"

His mood was also very bad. Five minutes ago, he was still complacent after repelling several waves of attacks from the Chinese army. Moreover, he had already thought of his own path of retreat, so he wasn't too worried.

Unexpectedly, five minutes later, the battle situation had a dramatic change.

"Set up the bombs and guard this door well!" If we don't pay a price, they won't be able to break this place! " The Bald Black shouted.

However, the mercenaries who were trapped in a tight encirclement despaired. However, there seemed to be only one way left for them.

"..."

The members of the B team who were attacking from the front only encountered a few mercenaries.

In terms of numbers, they had the advantage. It didn't take them much effort to finish off the mercenaries. As they walked, their surroundings were a complete mess.

"What's going on!" The members of the B team looked at the corpses on the ground and listened to the gunshots and explosions from inside as they asked in confusion.

Although they were charging head on, they were still extremely careful. After all, they were all made of flesh and blood.

"Looks like someone has already gone ahead of us." Lee Chen looked at the scene in front of him and laughed.

"One step ahead of us, could it be Shen Feng?" Chen Tieh looked, and it seemed that only Shen Feng was not there, and the battle scars were left behind by Shen Feng's weapon.

"Let's hurry up, we don't want to be left behind by a newbie." Vice team leader Chu Kun said to everyone in Group B.

The people in Group B looked at each other and smiled. Then, they quickly headed towards the underground center...

Looking at the members of the A team, there was not even a shadow of a living mercenary.

"Chief, could it be that Division B has already invaded?" Jiang Wenhao looked at the corpse on the ground and asked Fan Yunhai.

Fan Yunhai shook his head, "These people were all killed by the same person."

His battle experience could be said to be the richest in the entire Xuan Group.

The members of Group A saw the traces of the battle. Only Shen Feng had taken out his large caliber sniper rifle and looked at the marks left by the bullets.

"Hurry up and leave. The battle will be over soon!" Fan Yunhai growled.

"Yes sir!" Group A's members answered and rushed to the underground center together …

"..."

The underground center was extremely quiet. All of the mercenaries held their breaths as they stared at the steel door in front of them.

As this was the center of the research facility, the door was specially made. Even a bomb wouldn't be able to blow it up easily.

"Dang, dang, dang, dang …" A crisp knock sounded from the door.

The hearts of all the mercenaries jumped to their throats, cold sweat beading on their foreheads, bodies, and palms. They knew that the enemies they faced were abnormally strong, much stronger than they had imagined.

However, they still firmly believed that this door was unbreakable.

At this moment, the lock started to turn red. In the blink of an eye, it turned crimson, and at a speed visible to the naked eye, it began to slowly melt.

"What!" All the mercenaries widened their eyes as they looked at the scene before them in disbelief.

Several mercenaries shouted out and aimed at the melted door lock. Then, they started to fire their rifles.

However, the bullets did not even make a sound as they entered the melted steel.

When the gunfire stopped, the door creaked open...
