The two of them walked to the depths of the fourth floor, and stopped because they heard a chaotic noise.

It was a crackling thump of fierce battle, chaotic and noisy.

Lu Quan Jing listened for a while and said:

"Let's go, go over there."

As he spoke, Lu Quan walked towards the source of the sound.

"What's the location?" Yu Changsheng asked.

"Arsenal."

Lu Quan's expression was solemn, dragging the corpse and running quickly.

Yu Changsheng naturally understood why Lu Quan's expression changed drastically after hearing the voice, because judging from the previous situation, these fierce rubber demons all had the ability to use weapons, no matter whether they were in the right way or not, once they got a weapon with such a great lethality as guns, they would definitely be difficult to deal with.

But Yu Changsheng couldn't understand why Lu Quan knew that these fierce rubber demons with weapons were very dangerous, so he had to risk going there.

However, Yu Changsheng didn't ask, because he knew that he might not get a true answer.

The two of them continued to move forward, and most of the fierce rubber demons were attracted to the third floor by the yellow smoke, so although the fourth floor had a complicated layout, at least it was not blocked by these disgusting monsters. The skin of the corpse dragged by Lu Quan had been worn and cracked due to the high-speed running, and a large amount of mucus flowed, and Yu Changsheng had to run in front of Lu Quan in order to avoid slipping, and Lu Quan pointed the direction behind him.

The clatter and roar of bullets are getting closer.

"Boom-"

Turning the last corner, a deafening explosion sent a wave of sound through the entire corridor, shattering the glass in the distance, and an exaggerated hole appeared in the room at the end, and the power of the explosion pierced through the exterior walls of the building.

Yu Changsheng and Lu Quan were caught off guard and were both shocked to the ground.

In front of the smoke and sand there were many figures, one man seemed to be flying in mid-air, the other was holding a rifle, and there seemed to be three figures in addition to the two.

"That's Butterfly Dance?"

Yu Changsheng saw the colorful wings and shouted.

Brilliant butterfly wings fluttered in the chaotic dust, and in the hazy light and shadow, a violent aura loomed.

Butterfly Dance didn't react, Yu Changsheng chased after her, and Lu Quan also dragged the corpse to follow.

Yu Changsheng had just taken a few steps forward when he heard the sound of two grenade explosions coming from the dust.

The strong light flashed, Yu Changsheng covered his ears and was still buzzed by the explosion, the wall was collapsed again, the wind outside poured in, and the dust dissipated a lot.

Yu Changsheng also saw Butterfly Dance and the man with the rifle clearly, and there were three other people around them who were holding machine guns.

The man with the rifle was shooting the same maniac who had pointed a gun at his head.

"Great, you guys arrived at the right time!" Butterfly Dance was ecstatic when she saw Yu Changsheng and Lu Quan.

"How did you get stuck here? Why did you leave the parent cabin! Lu Quan said in surprise.

"The two of them are almost unable to support it, because I am flying fast, so I asked me to ask for help, but I didn't expect that as soon as I came down, I met the same madman who came down to look for us!" Butterfly explained.

"But the flowers and the grass are still on it?" Lu Quan glared at the fanatic not far away.

"Well, you haven't heard from you all this time, so I came down without worry. Those two guys were tied to a tree with a prison net, and they shouldn't be fine. Now stop talking this nonsense, it's dangerous here, get out of here! The fanatic said solemnly.

While speaking, Butterfly Dance and the others also withdrew to Yu Changsheng's side.

Yu Changsheng noticed that the other three people turned out to be the corpses of dead soldiers, I don't know who used what method to make these three corpses stand up and shoot with machine guns, and two of the soldiers' heads had already fallen off.

While Yu Changsheng was still watching, there was a sudden loud bang in his ears.

The sound of the grenade being unloaded and firing came again, this time in the direction of Yu Changsheng.

Yu Changsheng didn't have time to dodge, so he immediately released his evil energy, and prepared to resist the grenade with his hard arms.

But what he didn't expect was that the maniac's reaction was faster than him, and when the howitzer was still about ten meters away from Yu Changsheng, he actually used his gun to penetrate the grenade, causing it to explode in the middle of the process.

This marksmanship and reflexes are really staggering.

Yu Changsheng looked in the direction where the cannonballs were fired, only to see two huge figures appear in the dust behind him, which turned out to be two fierce rubber demons carrying howitzers, who were frantically chasing Butterfly Dance and the others.

The two fierce rubber demons carried howitzers on their shoulders, and also held high-velocity machine guns in their hands, and fired in a haphazard manner, the bullets were like flying flies, chasing the two people who fled, and the body of one of the soldiers had been completely pierced by the bullets, and he fell to his knees on the ground, but the broken arm had not stopped the designed action.

Although Lu Quan and Butterfly Dance were not far away from them, it didn't seem easy to run over, and when Yu Changsheng was thinking about how to support the two of them, he found a strong mana surging on the side.

Turning his head, Lu Quan didn't know when he had already put his steel fist on the ground.

The current Luquan was tense in his muscles, brewing a certain force, and green tendons appeared on his forehead.

"Boom thunder."

Lu Quan suddenly rushed forward and shouted a spell.

I saw that his two arms were stretched extremely long, and the whole person formed a slingshot, and the corpses of the two fierce rubber demons stopped in his closed hands, like two cannonballs ready to fire.

After running for five meters, Lu Quan suddenly stopped, and the inertia threw the elongated arm out directly.

In an instant, two flesh cannonballs smashed straight into the fierce rubber demon behind Butterfly Dance like meteorites falling from the sky.

Yu Changsheng's eyes lit up, he didn't expect the destructive power of the two cannonballs to be so amazing, they flew out against the roof of the shed, and the wall skin flew to the ground. One of the shells almost scratched the butterfly dance.

With a loud bang, the four lumps of flesh smashed together, and after the two fierce rubber demons holding weapons were hit by the corpses of their own companions, they let out a furious roar, and the yellow and red thick slurry splashed in all directions.

"Run! My machine-controlled puppets are all hung up, these guys are too fierce! The approaching maniac said.

"What is a machine-controlled puppet?" Yu Changsheng asked as he ran.

"A psionic trap that gives a dead corpse a temporary consciousness, acting as a virtual brain, but only performing a few simple actions in a specific pattern. The Maniac's puppets are all preset for gun operation. Lu Quan explained.

Yu Changsheng ran wildly behind Lu Quan, and this time he found that Lu Quan's speed was indeed a lot faster after getting rid of the burden.

At this time, Butterfly Dance also flew over, her appearance was embarrassed, her robe was already a little tattered, and stained with filth and scarlet blood, her face was full of tiredness, and her snow-white skin was already covered with a thick layer of dust, like a fallen butterfly that had been destroyed by a raging sandstorm.

"It seems that three people are still not enough to fully activate the energy lock, we have to speed up." Luquan replied.

"It seems that there is no way, those guys behind have already caught up, I will stay and cover, you guys run!" Butterfly Dance said.

"No, your mana level is higher, so I'd better stay!" The fanatic said.

"No, your physical strength is better suited to activating the energy lock than mana, and my butterfly powder can temporarily trap those dead fat people, so I'll cover for it!" Butterfly Dance's eyes burned, as if she had seen death as home.

Yu Changsheng watched coldly, after all, he didn't care who stayed, as long as he could reach the mother cabin safely.

Lu Quan and the madman glanced at each other, and after a little thought, the madman gritted his teeth and said:

"Well, if you can control them, you can hurry up and keep up!"

"Don't worry."

After the butterfly dance finished speaking, she spread her wings wide, and her gorgeous wings fluttered up and disappeared into the yellow smoke......
