Su Xiao put the stunned guards in a few shots, the magazine was emptied, he pulled the new magazine from the belt around his waist, and completed the reload in a very short time.

Turning over and entering the factory, Su Xiao's body was lowered, his hands were flat in front of him, aiming at an abandoned machine, and at the same time, his steps moved forward quickly.

Burst.

Su Xiao suddenly opened fire, and with a ding, a fire broke out on the abandoned machine, and the mercenary guard behind the machine retracted his head.

"expert."

The mercenary guard hides behind the abandoned machinery, and he removes his gas mask, revealing a white face.

Mercenary guards attempt to poke the gas mask out of cover.

Puff puff.

There was a huge momentum in his hand, and the gas mask was shattered in an instant.

Jingle, a swarthy object was thrown near the mercenary guard, and the mercenary guard was cold, and he subconsciously thought it was a grenade.

The mercenary guard made a judgment in an instant, he ripped off his shirt, threw it out, and threw himself in the opposite direction, trying to jump behind another cover.

Puff puff puff......

A rhythmic gunshot came, and several clouds of blood burst out on the mercenary guard who jumped in mid-air, and he was shot five times in the body, and landed with a pop, the momentum of the bullet changed the direction of his jump.

Five shots were taken to the torso, which was supposed to be a fatal injury, however, the mercenary guard rolled on the spot and ignored the gunshot wound.

Burst.

Su Xiao fired the last bullet in the pistol, the bullet entered through the mercenary guard's eye socket, and failed to break out of the brain, and the rotational force of the bullet instantly stirred the mercenary guard's brain into a paste.

Withdrawing the magazine and reloading it, Su Xiao's face was not very good-looking, he had shot the guard five times before, and the other party was still able to stand up.

You must know that the power of the 9mm caliber bullet is not small, and the distance between the two sides is about ten meters, with Su Xiao's marksmanship, all five shots hit the torso, and one shot even penetrated the lungs.

The enemy is very difficult to deal with, and with only a pistol, it is likely that he will not be able to cope with it.

Su Xiao walked towards the staircase leading to the underground, and a guard who had been seriously injured by shrapnel stretched out his arm and picked up the rifle beside him.

Su Xiao gave the other party a shot, and dragged a stun bomb from the opponent's waist, hesitated for a moment, he picked up a pair of gas masks on the ground and put them on.

Noisy footsteps were heard outside the factory, and a large group of guards had rushed to the factory gate.

Su Xiao pulled the tab of the detonator bomb and threw the detonator bomb towards the door, and he dodged into the staircase.

Collapse!

The stun bomb exploded, Su Xiao had already held his ears, and the white light and the factory suddenly appeared, and then there was a roar of pain, and the stun bomb at night would cause irreversible damage to the optic nerve.

Su Xiao walked slowly down the stairs, a corner appeared in front of him, he leaned against the wall on the side of the corner, pulled a small mirror from his waist, and watched the situation behind the corner through the small mirror.

More than a dozen guards stood guard at the bottom of the staircase, armed with various automatic rifles, their muzzles pointed at the top of the staircase.

Bang!

The gunshot came, and the cement on the wall next to Su Xiao's ear exploded, it was a stray bullet!

The cement shards cut through Su Xiao's cheeks, blood flowed down his cheeks, soaked from the corners of his lips, and the smell of rust appeared in his mouth, a smile appeared on Su Xiao's face, his heartbeat gradually accelerated, and the seals on his body that suppressed him flashed.

"It's hard to deal with."

Su Xiao threw out the black travel bag and stepped back quickly.

Sudden Sudden Sudden ......

Dense bullets were fired at the travel bag, which was instantly broken into rags, and large pits appeared on the rifle inside the travel bag, and at close range, the pistol was better than the rifle.

Poof.

A cloud of blood erupted in Su Xiao's shoulder, and he took two steps back, which was hit by a stray bullet that bounced off the wall.

There was a sound of footsteps above the staircase, and Su Xiao was blocked in the building.

When the gunfire under the staircase was sparse, Su Xiao stepped forward a few steps, leaned out of the wall with half of his body + head + arms, and quickly pulled the trigger.

Puff puff puff......

Several guards were shot directly in the head, and just as one guard tried to pull the trigger, the bullet had already entered his forehead, and his brain was splashing.

In the face of Su Xiao's terrifyingly accurate marksmanship, those guards immediately retreated to both sides of the staircase.

How could Su Xiao miss this kind of opportunity, he threw the pistol into his left hand, pulled out a short knife of about 40 cm from the trouser tube of his calf with his right hand, and rushed down the stairs in a few steps.

As soon as he rushed out of the staircase, Su Xiao immediately leaned down and looked around quickly.

There were six guards left, three armed with rifles, two with pistols, one with a grenade, six standing on the left and right sides of the staircase, two on the left, four on the right, and two on the left, one with a grenade.

The gun in Su Xiao's hand was raised, his breathing slowed down, and he pulled the trigger.

Burst.

The guard holding the grenade was shot, this shot hit his wrist, Su Xiao's original goal was to hit the grenade, but Lv.5's firearm specialization could not be accurate enough to hit the grenade, and Su Xiao was moving.

Su Xiao could only retreat and fire two shots in succession, headshooting the two guards on the left.

As soon as the two guards on the left side were resolved, Su Xiao's back was numb and he was shot, he immediately rolled on the spot, and craters appeared on the ground next to him.

Puff puff.

Su Xiao shot three times, the magazine of the pistol was emptied, the two guards on the right were shot in the head, one was shot in the throat, and the remaining one had already picked up the rifle and aimed at Su Xiao.

Of course, Su Xiao knew that there were several bullets in the gun, and the moment the bullets were empty, the short knife in his other hand had already been thrown.

With a brush, the short knife stabbed into the chest of the last guard, and the rifle in his hand lost its accuracy, and swept a few shots at a cement near Su Xiao.

Su Xiao immediately withdrew the magazine, and when the magazine was still in mid-air, the new magazine had been inserted and the bullet was loaded.

Poof, poof.

Two shots went down, and the last guard was shot in the head.

It's not that Su Xiao likes to hit the head, but because these guards are not ordinary people, if they hit the torso, as long as they don't penetrate the heart, their combat effectiveness will not drop too much.

While eliminating the last guard, Su Xiao quickly rushed towards the corpse of one of the guards and pulled a grenade from the corpse.

Rumble!

The sound of an explosion came from inside the stairs, and the powerful momentum sent Su Xiaoding back a few steps.

Boom, boom, boom.

One after another grenades exploded at the staircase, and Su Xiao hid behind a cement pillar, and he was in a basement with a size of several hundred square meters.

In the basement, there are rows of stainless steel flat tables filled with test tubes or beakers, and square plastic bags with white powder.

Some workers in chemical protective suits stood in front of the flat table, dozens of people, one of whom slowly leaned back, and a pistol was placed on the flat table not far from him.

Su Xiao raised his gun to aim and shot his head.

Two seconds later.

"Ahh

Dozens of workers screamed, and they subconsciously squatted on the ground, holding their heads in their hands.

Su Xiao threw the grenade at these people, most of them squatted on the ground and did not move, but three of them immediately jumped up behind the cover, and their movements were vigorous.

Poof, poof, poof.

Three shots were fired in frustration, and the three imposters who rushed to the bunker were shot in the head.
