Although this alternative way of killing looks unsightly and is suspected of bullying, it actually works very well, because during the attack, everyone can clearly see the terrifying movement speed of those shadow thieves on the map.

Chu Fan's estimation is that the speed of these guys is at least about 20 meters per second, which is equivalent to a car traveling at a medium speed, and when Chu Fan is condescending and attacks with the golden bison, the other party has a strong resistance to the deceleration of the bison, and the time limit can only last about two seconds.

Therefore, everyone didn't think about rushing down so early, but tried to kill as much as they could.

......

At nearly 3 o'clock in the afternoon, the number of zombies on the fourth floor was only about 200, and they were all at the far end of the map, and everyone's bullets had been punched, whether it was the main gun or the pistol.

At this time, Chu Fan nodded at everyone, and then, together, everyone fell towards the entrance of the cave!

After a few "bang, bang, bang......" sounds, their feet fell to the ground.

At this time, a large number of shadow thieves are rapidly advancing from a distance, and the speed is amazing!

Chu Fan threw two flashbangs in a row to cover everyone to pick up the bullets!

After a few seconds, the crowd filled a full load of bullets, and then began to attack the enemy with intensive fire!

Shadow Thieves and Death Barbie have similarities, that is, after entering the stealth effect, the movement speed will not decrease at all, and they themselves are better than Barbie's stealth effect, and the body is more transparent, if the eyes are not good, it is really not easy to see clearly, and the most annoying thing is that they are still moving back and forth, so that everyone's hit rate will not go up!

At the critical moment, Li Zitian's machine gun exerted its power!

Li Zitian is a machine gun expert, before entering this map, she adjusted the backpack, replaced AA12 with MG3-A, and together with L86, constituted her two main backpacks, MG3-A is powerful, and the trajectory is also good, the best thing is that it has a lot of bullets, 125 rounds in a magazine, and it is very sensitive, and many shadow thieves with residual blood have been swept by her, and they have been headshot!

But on the whole, it is still not optimistic, the Shadow Thieves are advancing too fast, and they are slowly coming to the city again!

At this time, Chu Fan inevitably gasped: "Alas, I'm going to burp, why bother?"

As soon as the words fell, there was another amazing roar, and a mushroom cloud rose in front of him, and at least more than 60 shadow thieves were instantly killed by the huge power of C4!

And the installer of this C4 is Zhou Xiaojie!

"Boy, well done!" said White Frost.

"Hehe, it's better to be taught by Brother Fan!"

Jiang Leiya sighed: "It's all bad to learn from Chu Fan!"

The opponent's menacing wave of offensive was defused by C4, and everyone's morale was also mobilized, killing the remaining remnants one by one!

At 3 o'clock, this floor is empty, and all the shadow thieves have been killed!

It's just that although he has played a perfect clearance, Chu Fan did not relax his vigilance, and after picking up all the falling objects on the ground with his comrades, they came to the entrance of the last layer step by step.

At this point, the entrance becomes a pipe again, and players have to rush down the pipe!

The task gave the latest hint, indicating that the BOSS had appeared, and its strength was extremely strong, and I hoped that Chu Fan and others would take good care of their lives.

However, it was also at this time that Chu Fan hesitated a little, and his eyes quickly fell on Zhou Xiaojie and Han Ya.

But unexpectedly, in the next second, Han Ya actually went around behind Zhou Xiaojie, knocked him unconscious with a knife, and didn't give Zhou Xiaojie a chance to speak!

Chu Fan was just about to talk to Han Ya, but Han Ya entered the pipeline first!

Helpless, Chu Fan could only follow this stubborn beautiful colonel and enter the pipeline together.

Bai Shuang'er glanced back at Zhou Xiaojie's not too tall body, and couldn't help sighing: "Young man, rest well, when you wake up, the boss's chrysanthemum will also be exploded by your brother Fan!"

......

Everyone entered the pipeline one by one, leaving Zhou Xiaojie alone. What is certain is that Zhou Xiaojie is definitely not the safest to stay here, but it is much better than them.

When everyone slipped down the pipe, the hard ground made them feel painful, and everyone lost more than 40 HP points.

This floor looks much more luxurious than the previous ones, at least the boss is willing to hire someone to decorate it, and the floor, walls, and overhead are covered with metal panels.

However, the whole space is not very large, it looks like it is only more than 1,000 square meters. It is a circular structure, and the surrounding wall is hung with a computer console, and an extremely tall, somewhat strange-looking boss is facing away from them, operating a computer.

It is said that this BOSS is weird because it is not completely humanoid, its upper body is still a human, with two thick arms, and the lower body actually turned into a snake shape, with a huge snake tail, but a huge scorpion needle appeared on the tip of the tail!

Chu Fan looked at this person and couldn't help but feel some pain in his eyes, not that he had been online for too long and his eyes couldn't stand it, but that this person looked very familiar, as if he was an acquaintance of his own!

An ominous premonition slowly enveloped Chu Fan, and he walked towards the person step by step, unexpectedly, before he could walk in front of the person, the man asked him, "Chu Fan, is the gun I gave you still working?"

Hearing this incomparably familiar voice, Chu Fan's gaze was almost dull, and he stared at the other party as if he was dumbfounded: "Lei, General Lei Wei!"

Everyone was also surprised: "How can this be?"

The boss turned around, and everyone realized that his appearance was exactly the same as Lei Wei's, but his body was no longer the body it used to be, even the upper body was wrapped in a layer of snake-like scales, and his face, neck, arms, and blood vessels showed a terrifying cyan!

Cataclysmic Serpent Thunder, a terrifying existence with 4 lines of green blood!

To be honest, sometimes, the most terrible thing is not that you don't know the truth of things, but that after seeing things, you can see the truth and essence at a glance, and this truth is something you don't want to deduce!

There is no doubt that the reason why Lei Wei was hit by a sniper rifle of a biochemical soldier in Tianzhou City before and did not explode has been found, and that is because there is a guy with a very high IQ in the zombie camp, and it did not kill Lei Wei, but deliberately left his life and transformed him into a biochemical zombie!
