Two peerless stunners who were too beautiful to talk to roll around on the ground in their arms, and one of them kept moaning: "I want you...... I want you ......"

It was supposed to be a nosebleed-spattering scene, but the scene in front of him was brutal and bloody.

Du Fei is full of enthusiasm, much more exciting than the underground dog fight, of course, the eye-catching degree of the scene is incomparable.

Rebecca exerts her ability to devour cells, frantically devouring the flesh and blood of the evolution of the beautiful snake. The beautiful snake activates all the toxin cells in the body, and 4 snakes grow behind it, biting Rebecca's body and constantly injecting venom into her body.

While Rebecca devours flesh and blood to grow stronger, her body continues to fester.

While injecting venom into Rebecca, the beautiful snake evolution also devoured Rebecca's flesh and blood, but her devouring speed was far less than Rebecca's.

Rebecca gradually realizes that even if she completely devours the beauty snake evolution, there will be very little left of her body in the end. She began to look at Du Fei with pleading eyes and said, "Help me, as long as you are willing to help me, I will be your slave in the future, I am willing to be your sex slave, help me ......"

Du Fei saw that the merger of the two stunners was nearing the end, and was about to take a shot to serve them, when a red alarm light lit up in the observation room.

Then I saw a line of prompts appear on the display screen of the observation room: "All passages in the laboratory are closed, the advanced self-destruct program is activated, the countdown begins, and the self-destruct device will be detonated in 59 minutes and 59 seconds." ”

When Du Fei left the control room, he didn't destroy the server inside, and he didn't know who started the self-destruct program. With such a tight underground lab, the self-destruct procedure must be perfect, and it is really a bit of a hassle to get out safely now.

And the person who started the self-destruct procedure, or should be called a corpse, turned out to be the old professor. After he was bitten by the evolution of the beautiful snake, he was injected with zombie medicine by the glasses man Ah Wing, and as a result, he became a zombie. The old professor who turned into a zombie still retains a certain level of intelligence, and when he was bitten by the beautiful snake evolution, his spirit also became sober, so after being kicked by Rebecca, he crawled to the control room to start the highest level of self-destruction program.

The self-destruction procedure of this underground laboratory is divided into levels, and the low-level self-destruction procedure is the poisoning procedure, which is used by researchers when they are ready to temporarily abandon the laboratory and are afraid of the unknowable mutation of the test subject. The lab will not be locked down after start-up, and the lab will be shut down by the scientists.

The intermediate self-destruct procedure is initiated in the event of an accident in the laboratory, allowing 60 minutes for personnel to evacuate, then locking off the laboratory and finally detonating the self-destruct device.

The last level of self-destruct program is to immediately lock down the laboratory, and the countdown time is 60 minutes to detonate the self-destruct device, destroying the entire laboratory, and even the scientific researchers cannot leave, this is a suicide self-destruct program, which is usually not used, but this zombie old thing has activated the highest level of self-destruction program.

"Cluck...... The self-destruct program was initiated. Now only I know how to escape, and if you don't want to die, help me. Rebecca said with a pleasant smile.

Du Fei ignored Rebecca's words, and planned to use the [Fire Dragon Play Bead] to burn them to ashes together, but suddenly smelled that something was wrong with the air, the taste of the air did not change, but with the special sense of smell of the awakened, he still felt that something was wrong.

"You'd better not play with fire, after the self-destruct program starts, the lab starts to be filled with carbon monoxide, and after thirty minutes, it detonates, and the explosion is much more powerful than a bomb." Rebecca said.

Du Fei took out a gas mask from the folding space and put it on his face, although the awakened can metabolize CO at a very slow rate, inhaling too much CO will still affect the body.

Then a sharp blade appeared in Du Fei's hand, and he walked over to kill the evolution first, and then cut off Rebecca's limbs, hanging her life, and wait until she left here.

Du Fei stepped next to the evolution of the beautiful snake in two steps, and slashed down with a single sword. The blade slashed through the slender neck of the beautiful snake, and the entire beauty head was cut off by the knife, and a stream of green blood spurted out from the broken neck. The beauty's head rolled on the ground twice, still glaring at Du Fei with her primal instinctive killing intent.

A snake head that had been biting Rebecca shook its head violently and rushed towards Du Fei, biting as soon as he opened his mouth. Du Fei retreated two steps back, dodged the rushing snake head, and then slashed the snake head with a swing of his knife.

At this moment, a white jade-like poisonous snake suddenly shot out from the severed neck of the beautiful snake, but this snake did not shoot at anyone, but flashed like a white lightning bolt into the pipe of the glass nutrition warehouse.

Seeing this, Du Fei moved his feet and rushed up to cut off the transportation pipeline. The pipes were cut off, and the white jade snake was also cut in two, but the snake's head burrowed into the complex and intertwined pipeline system, and it was impossible to find it.

Rebecca took this opportunity to turn around and want to escape, but just as she was about to become invisible, she was discovered by Du Fei.

Du Fei had already made preparations, and as soon as the source ability moved, three chain guns pierced Rebecca's body at the same time. After the chain gun penetrated Rebecca's body, it immediately transformed into countless spikes embedded in her body, and the chain of the chain gun was grabbed by Du Fei in his hand.

Du Fei said lightly: "It's best not to play tricks, otherwise if I move my hand, your head will immediately turn into many petals." ”

"From now on, I will belong to you from the inside out, from the bone to the skin." Rebecca's body was covered with all kinds of steel thorns, and she still didn't forget to throw a wink at Du Fei.

"Look me in the eye and take out the memory card you stole." Du Fei walked up to Rebecca and said.

Rebecca straightened her chest, her torn shirt of the two peaks exposed, and in the enchanting ravine between the twin peaks, a card was inserted.

Du Fei stretched out his hand and pulled out the memory card from between the twin peaks, and the two jade peaks were trembling together, which was really too tempting.

"Can you pull your stick out of my body first?" Rebecca rubbed two large breasts on Du Fei's chest, pointed to the chain gun inserted in her abdomen that looked like a hedgehog and said, but this was too ambiguous.

"I'll pull it out when I'm done." Du Fei smiled and replied in the same ambiguous tone.

As he spoke, Du Fei led Rebecca with a chain to search in the underground laboratory, and finally came once, how to say that the reserves of energy crystallization in a laboratory like this are hundreds of grams. If there are a few more zombie weapons like the fourth child wearing nano combat suits, it is not a problem to earn dozens of grams a day.
