"Formalin?!"

The pungent smell was too strong and too familiar, so that Dong Hongfeng on the side immediately recognized it.

At this time, being poured on his body by formalin, Ben 1 showed a painful look and struggled frantically. And if you look closely, you can see that the muscles and muscles on the body that were originally wriggling like pythons have atrophied after being contaminated with formalin solution.

"This ...... How can it be? You can't possibly know! ”

Ben No. 1 screamed in his mouth, still puzzled and suspicious in his voice.

But Chen Mu didn't have any intention of explaining, at this time, it was the best time to kill Ben No. 1, and Chen Mu naturally wouldn't miss it.

He steadied himself on the ground, still holding the alloy dagger in his hand. The quality of this alloy short knife is indeed extraordinary, and the top is as smooth as washing, as if it has not been used.

With a flicker, Chen Mu had already rushed forward.

At the same time, Dong Hongfeng's eyes flashed, and he rushed forward without hesitation.

Not only Chen Mu saw the opportunity, Dong Hongfeng also keenly grasped this opportunity and made a decisive move. His purpose is very simple, that is, to compete with Chen Mu for the opportunity to kill Ben No. 1. After all, the rewards of mission 4 reward the killer with 3 potential points, which is a big attraction for any visitor.

It's just that Dong Hongfeng is farther away after all, although his speed is not much slower than Chen Mu at full strength, but it is still one second behind!

Laugh at!

Chen Mu jumped high again, and the alloy short knife in his hand had already pierced Ben No. 1's head.

Ben No. 1's screaming in pain stopped abruptly, and Dong Hongfeng, who rushed over, couldn't help showing disappointment and remorse on his face, how could he not regret it if he missed 3 potential points by just a fraction.

However, at this time, Chen Mu, who had succeeded in one blow, suddenly changed his face.

I saw Ben No. 1, who had an alloy short knife in his eyebrows, his head turned suddenly, and his two eyes instantly turned red and looked at Chen Mu: "You think it's so easy to kill me?" ”

"Roar!"

Ben No. 1 roared violently and grabbed Chen Mu with one arm.

Although Chen Mu was surprised when he saw this, he did not hesitate, and his feet stepped Ben No. 1's huge body, and at the same time jumped backwards violently.

Although Chen Mu's reaction was fast, he was still swept into his right leg, landed unsteadily, and fell to the ground.

Immediately, Chen Mu rolled a few times violently, dodged farther away, and only felt a sharp pain like a pinprick in the calf of his right leg. Chen Mu's heart was a little shocked, this time it at least hurt his bones.

On the other side, Dong Hongfeng saw that Ben No. 1 was not killed by Chen Mu, he was both surprised and happy, and rushed forward.

His shield fell to one side, and he only held a knife in his hand, and his face was fierce and fierce.

Ben No. 1 was about to pull out the alloy short knife that was still inserted in the center of his eyebrows, but he didn't react, and was slashed in the leg by Dong Hongfeng.

Dong Hongfeng, as a secondary strengthener, is far more powerful than ordinary people, and much higher than Chen Mu. As he slashed with all his might, a bucket-thick leg was directly severed.

With a pop, Ben 1 fell down.

At this time, Dong Hongfeng took advantage of Ben No. 1's struggle to stand up, and suddenly stepped forward again, and the knife in his hand slashed hard.

Brush!

Ben No. 1's head was directly split off and rolled to the side, and at the same time, the monster's huge body fell with a thud, and there was no movement.

"Ha, ha!"

Dong Hongfeng couldn't help but let out an excited laugh from his mouth, his voice was a little out of tune, and it seemed that even he didn't believe that he had finally succeeded.

3 potential points, after getting it, he can even consider strengthening it for the third time.

At this moment, the great joy even washed away the grief and anger caused by the mutilation of the body.

However, at this moment, there was a sudden "be careful" in his ears, which made Dong Hongfeng's heart feel cold, and he subconsciously hid to the side.

Snort, a soft sound came from his waist, Dong Hongfeng couldn't help but exclaim, and looked down.

I saw a huge hand pull past his body, and the long pointed nails cut through the clothes on Dong Hongfeng's waist.

Dong Hongfeng couldn't help but be a little lucky, if he hadn't dodged in time, I am afraid that this time he would have been able to directly disembowel.

He endured the horror in his heart and looked at it again, only to see that the monster that had obviously fallen down and did not move just now actually moved again.

On the other side, Chen Mu, although he saw Dong Hongfeng cut off Ben No. 1's head, was not as relaxed as Dong Hongfeng. Because at the moment when he stabbed the alloy short knife deeply into the center of Ben No. 1's eyebrows but didn't kill him, a thought surged in Chen Mu's heart, since he couldn't kill Ben No. 1 in this way, how could the monster that was stabbed into the eye socket die so easily?

Because of this thought, Chen Mu still focused on the monster, and the moment he saw the monster move, he reminded Dong Hongfeng loudly.

I saw that the monster was struggling to move, and after scratching Dong Hongfeng, it tried to stand up, but with only one leg and one hand, it could not support its huge and heavy body, and it fell down just halfway up.

"Haha, he's immortal!"

Ben No. 1's head, which was cut off, still had an alloy short knife stuck in his eyebrows, and his face was covered with dust, which was extremely embarrassing. But he still didn't die, and even laughed.

Chen Mu walked over, stepped on his face, and pulled out the alloy short knife in the center of his eyebrows with his hand.

Immediately, he ignored Ben No. 1's angry scolding, and rushed towards the monster with an alloy short knife in his hand.

"It's mine!"

At this time, Dong Hongfeng suddenly screamed, and the long knife slashed over.

The monster could not stand up, or even move its body, instinctively blocking it with its arms.

"Drink!"

Dong Hongfeng shouted loudly and slashed down with all his might, the arm that the monster had just raised couldn't withstand his strength and the sharpness of the long knife, and was immediately split off and fell to the ground.

At this time, Chen Mu had already rushed over.

Dong Hongfeng was worried that Chen Mu would succeed, and seeing that the monster's only remaining hand was also cut off, his heart relaxed, his body was closer, and the knife in his hand swung towards the monster's neck.

If it hits this time, the monster's basin-sized head will inevitably be cut off like Ben No. 1.

However, just as Dong Hongfeng was about to succeed, on the other side of the monster, a long whip-like thing suddenly stabbed over.

This attack was too unexpected, Dong Hongfeng couldn't imagine how the monster who had lost his two arms could attack, so he was a little lax.

Seeing that the other party still had means of attack, Dong Hongfeng's face turned pale with fright, and he hurriedly dodged.

Fortunately, the monster's counterattack was completely powerless, although it was unguarded, it only cut through a little bit of flesh on Dong Hongfeng's waist, which was nothing to Dong Hongfeng.

However, this time it scared Dong Hongfeng enough, he looked carefully, and the long whip-like thing actually extended from the other side of the monster's shoulder, showing a dark red color, exactly the same as the muscles wriggling in other parts of the monster's body.

If you look closely, the monster's arm, which had disappeared in the explosion, had grown a little. What I attacked just now is the part that grows out.

The head is still immortal after a heavy blow, and it is completely understandable that the monster has this kind of vitality of limb regeneration.

However, for monsters, this arm has not grown out after all, and it is not easy to hurt Dong Hongfeng's flesh and skin.

Just when Dong Hongfeng was a little angry that he was taken aback, Chen Mu had already rushed over, the alloy short knife in his hand was at the monster's neck, and his body rotated around the monster in half a circle.

Boom!

The monster's huge head, completely cut off, fell to the ground. Its massive body also fell again.

Dong Hongfeng gritted his teeth when he saw it, did he finally let Chen Mu succeed?

"Not dead yet?!"

Chen Mu's shout made Dong Hongfeng a little surprised, and he turned his head to look. Sure enough, the monster's mouth was still moving, revealing its beast-like criss-crossed teeth, as if waiting to be devoured. And the monster's body, those muscles are still squirming.

"This ...... This ......" Dong Hongfeng was dumbfounded, "how do you kill it?" ”

Even if you cut off your head, you won't die, and it's really shocking to have such a strong vitality.

"Ha, I'm immortal, I'm the future! Don't try to kill me! ”

Ben No. 1's maniacal laughter rang out from the sidelines.

Chen Mu glanced at him, walked over, stepped on his face again, and stomped all the sounds of Ben No. 1 on the soles of his feet.

Puff puff!

Dong Hongfeng used a long knife to cut the monster's head and body into several pieces, and he was so tired that his forehead was sweating, but when he looked at it, he found that the monster's body was still squirming.

"This ...... How to deal with it? ”

Now the monster has completely lost the ability to resist, but if you can't kill it, the mission can't be completed.

Chen Mu walked over, took out a large bottle of formalin solution from the watch space, and poured it on the monster's body. With all the pouring finished, the monster's body squirmed to a halt.

Dong Hongfeng was stunned for a moment, and couldn't help asking, "How do you know it's afraid of formalin solution?" ”

Ben No. 1 also asked before, but Chen Mu didn't answer, but at this time he spoke: "Do you remember that I once pulled out a catheter from Ben No. 1's head to inject formalin solution?" ”

"Hmm!" Dong Hongfeng nodded, "Ben No. 1 said that it was to prevent him from rotting ......"

Chen Mu shook his head: "As far as I know, formalin can block the synthesis of nuclear proteins, so it can kill viruses and bacteria, and the side effects are very large." If you really want to preservative, you can use other methods with fewer side effects. So I suspected at the time that the reason why Dr. Z gave Ben 1 formalin solution was not for Ben 1's sake, but to control Ben 1. Otherwise, with the ability of Ben No. 1 to mentally control others, he will also be able to make waves. And Ben No. 1 is actually the same as this mutated monster.,Both have the same virus.,Since formalin can control Ben No. 1,,It should also be able to affect this mutated monster.,So after I saw formalin,,I put it away.,Later I tried to use it.。 ”

"Based on your guess alone, you dare to try? What if it's wrong? Dong Hongfeng asked.

"If it's wrong, it can't be helped!"

Chen Muyi waved his hand, turned his head to look at the monster body that was still wriggling, and did not explain again.

He didn't fully explain it, but the biggest source of information for these speculations was Dr. Z's diary. When Chen Mugang got the diary, he only looked through it cursoly, and then studied it carefully after coming to the laboratory. The various information in it, although it was only a few words, gave Chen Mu a lot of inspiration. If it weren't for that, I'm afraid it wouldn't be easy for him to think of this, or even if he did, he wouldn't be so sure.

At this time, the surroundings fell silent, and the sound of the large barrel rumbling and stirring in the north building came. Unexpectedly, after the previous explosion, the machine was still running.

After hearing the movement, Chen Mu turned his head in the direction where the vat was......
