I don't know how deep the elevator room is, the wind is whistling in Mu Mu's ears, and I can hear the sharp screams of many bird-like monsters overhead, and she can't help but feel numb with her courage, and secretly said that this time she is afraid that it will be more than lucky, and she can't help but tense her whole body, and subconsciously clench the sniper rifle.

"Don't worry, it's still about a hundred meters from the ground, can you take down those bird-like monsters chasing above?"

It wasn't until Lu Shaoxi's voice sounded in his ears that Mu Mu Huoran woke up. She is slender and petite, more than half a head shorter than Lu Shaoxi, but now that Lu Shaoxi is holding her, her ears are right next to Lu Shaoxi's mouth.

Mu Mu realized that she was being hugged by this guy, and she couldn't help but feel hot, but Lu Shaoxi's words just now were very skillful, not saying "don't be afraid" but saying "don't worry", and couldn't help but take care of the arrogant Mu Mu's face, which made her calm down.

"Yes. Mu Mu heard the sound of wings fluttering overhead, and a huge three-headed eagle was only three or four feet away from them, and it was chasing closer and closer. At the critical moment, Mu Mu didn't talk nonsense, and suppressed the girl's natural shyness, she let Lu Shaoxi hug herself, raised her head and raised her gun, aiming at the target above her head.

Her movements are extremely fast, but her hands are steady.

"Don't hit the big ones in the lead, but the three-headed eagle on the left and count the fifth. ”

"Good. Mu Mu couldn't think about it, how could Lu Shaoxi see the "chasing soldiers" above his head so clearly, and he pulled the saka machine when he aimed at the target.

"Bang!" There was a soft sound, and the three-headed eagle monster that was targeted screamed in response, and its body was beaten upwards and flew out, colliding with the rest of the bird-like monsters that swooped down behind, making a mess.

Lu Shaoxi saw clearly with his perspective eyes, and couldn't help nodding secretly, when it came to the speed and accuracy from aiming to shooting, Mu Mu was really not much inferior to him, and there were not many people in the world who could match him.

Seeing that the several giant monsters that took the lead in the pursuit were even more angry, and they were accelerating towards with a hiss, Lu Shaoxi shouted, "Go on!"

Mu Mu already understood Lu Shaoxi's intention to attract monsters, she held the gun in both hands, and in the blink of an eye, she fired several more sub-shots, knocking the small monsters behind the giant monster out one after another.

"The sniper rifle is out of ammunition, and now it is inconvenient to change the gun. ”

Mu Mu's bullet clip was wrapped around his waist and abdomen, and he happened to be hugged by Lu Shaoxi.

"It's okay, it's going to be at the bottom. Seeing that the monsters were about to catch up with the two of them, Lu Shaoxi suddenly kicked the side wall, and his body changed from falling rapidly to flying diagonally.

"Boom!" Lu Shaoxi arched his back like a fish, turning into a cannonball and hitting the wall on the other side, knocking out a big hole in the entire wall. If there is a martial arts master present, he will definitely exclaim, this is the extremely rare seven-grade martial arts "Tongbei Hun Yuan Jin"!

The giant monsters that took the lead with dozens of small monsters roared past the two of them, rushing downward, but they were extremely capable of flying, and immediately pounced from below, chasing after them.

Rubble flew, steel bars were broken, dust and smoke were raised, Lu Shaoxi and Mu Mu broke through the wall and stepped on the white floor.

On the other side of the wall is a long, bright and neat passageway!

Mu Mu was surprised to find that there were dozens of offices and laboratories on both sides of the passage, and the security personnel in black security uniforms and the experimenters in white coats came and went, busy and orderly.

The intrusion of Lu Shaoxi and Mu Mu was like a boulder thrown into the lake, and the researchers and security personnel in the passage were stunned.

But before they could react, Lu Shaoxi had already pulled Mu Mu like a phantom to pass through the passage of dozens of feet and stood still, and several security personnel with guns were about to rush over to ask, when they suddenly heard a huge roar coming from the hole, and a large number of hideous and terrifying-looking winged monsters poured in and swooped in the direction of Lu Shaoxi.

Mu Mu broke away from Lu Shaoxi's hand holding her slender waist, and with a shake of her hands, the sniper rifle had been put back on her back, and there were two more silver pistols in her hands that were about to shoot, "I have a way." Lu Shaoxi held her down, pinched her lips and whistled.

This whistle is sharp and sharp, and it is very similar to the 3D phantom blown by Professor Fei above!

At the sound of the whistle, the monsters froze and attacked the researchers and security guards like crazy, and the giant monsters in the lead rushed around like prehistoric pterosaurs twice the size.

Several security personnel and researchers avoided it, and were swallowed by the monsters one by one, the blood and the putrid stench of the monsters spreading, causing the rest of the researchers to scream and flee. But most of them are ordinary people, where can they escape the attack of these monsters with extraordinary strength, and for a while, screams for help are everywhere, and the underground research institute is like a hell on earth.

Mu Mu was used to seeing life and death, but the tragic situation in front of her also made her look away.

Lu Shaoxi said coldly: "Don't think that this is miserable, let's go, the sins committed by these people will not be atonemented by a hundred deaths!" He walked briskly in front, Mu Mu was stunned, and involuntarily followed behind him.

This underground research institute is like a large labyrinth, covering an area of three or four kilometers. Lu Shaoxi took Mu Mu to kill several security guards with guns, and by the way, kicked and broke the office doors everywhere.

Mu Mu soon discovered the darkness and horror of this underground research institute, there were many dissecting rooms and biochemical laboratories inside, not only dissecting beasts, but also human and biochemical living cultivation experiments!

The inhumane and cruel experiments carried out in the office are outrageous, and Mu Mu's iron heart is angry when he sees these scenes.

The staff in the entire underground research institute were afraid of no less than a thousand people, monsters were raging, and outsiders were invading, which quickly caused an alarm, and a large number of heavily armed security guards and dozens of super powerhouses of the Tongmai Realm who were obviously biochemical martial artists heard the news.

Lu Shaoxi didn't talk nonsense with them at all, he was ruthless, and the pulse interceptors attacked one after another, like a tiger entering a flock. Coupled with Mu Mu's double guns, in less than two minutes, there was no longer half a standing person on the ground.

Lu Shaoxi continued to stimulate those monsters to wreak havoc with a whistle, and then turned to Mu Mu and said, "I'll go find the person in charge of this research institute, and you stay?"

"Person in charge?" Mu Mu suddenly remembered: "You mean Professor Fei?"

"That's right. He's kind of the boss here. ”

Mu Mu also hated this person, so he clenched his pistol and gritted his teeth and said, "Do you know where he is?"

"It's right below us. Lu Shaoxi pointed to the ground.

Before he could finish speaking, suddenly the entire floor caved to the ground, and a huge hand full of hair grabbed at the two of them.

This change was extremely sudden, and the giant hand was even faster and more powerful, smashing over like a pillar, and the wind was fierce, no less than Mr. Qu's martial arts attack!
