Underground secret laboratory.

Cindy's back quickly disappeared.

At this time, Ao Gu looked at another middle-aged man behind him.

His eyes wandered, and soon fell on the middle-aged man's mechanical right arm glowing with silvery white light.

"Mr. Badal, considering the conflict between you and the Hidden Dragon Mercenary Group, you should go meet those two giant dragons for a while, right?"

Badal shook the mechanical arm and said with a sneer: "You don't need to be reminded by Master Aogu, our Emperor Mercenary Corps has been fighting with them for a long time, not to mention that he killed Carlson in Jiangcheng not long ago."

"Since that's the case, then you should also take your mercenaries to have a look."

……

now.

Laboratory hall.

Wu Tao looked at the guards rushing in, and pulled out a newest Type [-] pistol from his waist.

He came here alone, so naturally he wouldn't just bring a dagger.

Raise your hand and shoot.

"Bang bang bang..."

Fourteen bullets, fourteen men.

Every hit!

"Ah ah ah..."

After a series of screams, the guards who rushed in all fell down.

Taking advantage of this opportunity, Jiang Wuyan picked up a Type [-] assault rifle and said, "Boss Wu, you still have six bullets."

"You can still hear it. It seems that they didn't make you lose your combat power." Wu Tao changed the magazine in an instant and smiled lightly.

"Then I have to thank them for asking me to make experimental materials." Jiang Wuyan's voice suddenly turned cold.

Wu Tao heard the anger inside, and calmly said: "If you want revenge, then follow."

Dodging and rushing towards an exit.

Jiang Wuyan immediately followed behind.

The underground laboratory is very large and consists of many rooms and passages.

These rooms and passages surround the Laboratory Hall, providing it with all the resources it needs.

But this time, Wu Tao did not choose to leave the passage where the experimental subject was imprisoned.

gallop all the way.

The two entered a room.

But suddenly, Wu Tao stopped.

So quiet!

Inside and outside the room, there was no sound at all.

Wu Tao's face became more serious.

The guards in this underground laboratory are definitely more than the dozen or so who killed them. Since Raphael has sounded the alarm, those people should be surrounded. How can it be so quiet here?
Wu Tao held his breath and raised his five senses developed by experimental drugs to the extreme.

"Dong dong..."

Within a hundred feet, including his own heartbeat, any movement came over.

After a while, the corners of Wu Tao's mouth curled up slightly.

"Is there someone outside?" Jiang Wuyan frowned and asked.

Wu Tao nodded slightly and made several gestures to him.

Then, he rushed out suddenly.

Suddenly, seven or eight guards rushed out from the corners on both sides and surrounded him.

"shot!"

Wu Tao yelled, and his whole body fell to the ground in an instant, smoothing out to the front.

Immediately afterwards, the Type [-] assault rifle rang out.

Thirty rounds of bullets were released directly.

"Ah ah ah..."

After a series of screams, seven or eight guards all fell down.

Jiang Wuyan's figure did not stop at all.

With a strong foot, the whole person leaps up.

Cooperating with Wu Tao, he rushed up and down to the corner not far away.

"Bang bang..."

Another series of gunshots rang out, and the other guards hiding around the corner were also eliminated.

Wu Tao dropped the [-]-type pistol in his hand, picked up a [-]-type assault rifle, and walked quickly.

In a blink of an eye, the two rushed a distance.

But again, he was surrounded by the rushing guards again.

After a fierce gun battle, the two eliminated everyone and rushed forward again.

After several times, Wu Tao suddenly stopped.

He looked at Jiang Wuyan, who was out of breath, and his face darkened: "We can't go on like this anymore. The enemy wants to use this refueling tactic to exhaust our physical strength, and then give us a fatal blow."

Jiang Wuyan took a few deep breaths and asked, "Then what should we do?"

"Whoever attacks the enemy must be saved, let's go."

Wu Tao gave a cold shout, and took the lead in rushing towards the elevator.

That elevator is the passageway to leave, if the people behind the command continue to send those useless guards to consume their energy, they will just watch them leave.

And once the people behind want to stop it with all their strength, they will be exposed in front of their eyes.

After solving two groups of guards who blocked them, the two entered a passage in front of the elevator.

Just as he stepped out, suddenly, five machine guns came firing.

Wu Tao quickly avoided.

Behind him, Jiang Wuyan couldn't dodge in time, and was shot in the left shoulder.

But the two of them did not back down, and before they could stand still, they fired several shots one after another.

"Ah..."

After a few screams, the machine gunners guarding here were all eliminated.

"How is it? Are you okay?" Wu Tao hurriedly asked when he came to Jiang Wuyan.

Jiang Wuyan looked at his left shoulder, smiled and shook his head: "It's just a broken arm, it's okay."

Wu Tao breathed a sigh of relief, turned around and found that the elevator stopped in mid-air, and frowned again: "I didn't expect them to take precautions in such a timely manner that even the elevator stopped."

Jiang Wuyan's expression froze, and he said in a deep voice, "Can't you go up?"

"Since you have come to this secret underground laboratory, you still want to go up, you are so naive."

Not far away, an arrogant voice came with a laugh.

And as the sound fell, countless guards rushed out like flowing water.

"not good."

Wu Tao's expression changed, he stepped forward, picked up a machine gun, and shot away.

Jiang Wuyan had one arm and found it difficult to operate a machine gun, so he picked up a Type [-] or [-] assault rifle again and joined the battle.

The crowd was fierce, and the bullets were fired without stopping.

Gunshots, exclamations, screams...

These terrifying and chaotic voices lasted for a long time, and finally subsided completely after the last scream came out.

Wu Tao and Jiang Wuyan glanced at each other, both breathed a sigh of relief.

But suddenly, another bullet was fired without warning.

"boom!"

Jiang Wuyan snorted and was hit on the right arm.

The five-six-type assault rifle that had been changed many times fell down without any accident.

"you wanna die!"

Wu Tao frowned angrily, picked up the machine gun, and shot straight away.

"Bang bang bang..."

After a series of gunshots, the figure disappeared.

Wu Tao's footsteps flashed and followed.

The bullets from the machine gun in his hand were shot out desperately.

And even though the figure was very embarrassed, he could still shoot back from time to time.

The two chased and fled like this, and came to the end of a passage.

Suddenly, the figure stopped.

As soon as he turned around, the white face looked over with a sneer.

"Black-clothed Canglong, you're out of bullets."
