On the fourth floor, which can be described as a gathering of heroes, all the zombies seemed to have been summoned in some way, and they were all gathered together, blocking the only staircase leading from the fourth floor to the fifth floor.

That's right, it's the only way, there was originally another one, but it's a pity that it's broken for more than one reason.

"Damn! What kind of dragon gate array is this?!" Zhang Yang was confused.

Chu Fan looked at these guys and couldn't help but take a deep breath: "It seems that the fifth floor is not so easy to reach!"

On the big map, the fifth floor clearly shows that there are "treasures", and these guys are the guardian beasts guarding outside the treasure!

The thing to do is simple, and that's to kill them all!

Thinking of this, Chu Fan showed a wicked smile: "Did Xiaoyang find any special circumstances?"

"Special circumstances?"

Zhang Yang unfolded the big map and glanced at it, and had an epiphany: "I understand, all the zombies in the main building are concentrated here, so if we play well, we can kill them in one go." Just, can we do it?"

Chu Fan grinned, and unhurriedly took out a long-planned C4 from his pocket: "What do you say?"

Zhang Yang was overjoyed: "Damn!C4!brother, where did you get it?"

The corners of Chu Fan's mouth raised slightly: "In the cellar of Nanli Xiang's family." ”

"I'll go, she still has a cellar?"

Chu Fan dumped him: "You stinky boy, you really didn't search carefully, didn't you see this?"

"Hey, hey, I'm sorry, this is my negligence!" Zhang Yang smirked for a while, then calmed down and turned his gaze to the boss in front of him.

This BOSS is a legendary 6-star BOSS, named Dark Dean Sasaki, with a level of 50 and a HP of 10 million, which is double that of the previous beautiful nurse, and its AC is not high, only 2000, but the attack power has reached an astonishing 950, which is really against the sky. He holds a long, sharp scalpel in his hand, and has two abilities - Dark Scarnation and Clever Hand Corpse Heart.

Dark Slaughter is an active attack skill and a melee skill. And the magic hand corpse heart is a passive skill, this skill is even more annoying, it is a skill to ensure that the zombies around you are always close to you, and hatred is not lost.

This is also the reason why Chu Fan took out C4.

However, there is only one C4.

Tactics can be similar, but it's a big problem to replicate the classic tactics of the old days here.

Chu Fan and Zhang Yang did not exchange news, so they knew that there was a problem that must be unavoidable.

With their level of operation, it is easy to blow up these minions, and even make the boss suffer joint damage, but the power of the C4 explosion is too great, if the sound cannot cover the gunshot of the beauties, then the zombies by the artificial lake will inevitably be chaotic and hateful, and rush to the main building, in this case, the chance of Chu Fan waiting for death to hang up is very high.

Now, you have to communicate tactics with the beauties.

Fortunately, Nan Li Xiang's family is really an arsenal, as a professional soldier, and a professional soldier of no low rank, her family not only has a radar, but also a communicator.

Therefore, Chu Fan quickly discussed a more complicated tactic with the beauties.

After this tactic was agreed, Chu Fan and Zhang Yang didn't say a word, and rushed in the direction of the dark dean, and they rushed over side by side, this tactic was obviously a little weird!

Just when the two of them were less than 10 meters away from the dean, the dean's eyes were focused on Chu Fan's body, and without saying a word, he rushed towards everyone with his little brothers!

I have to say that the dean's speed is not as fast as Chu Fan, and even compared with Zhang Yang, who is also wearing mobile acceleration equipment, it is a little inferior, and the younger brothers around him are even more so.

At this time, Chu Fan shot the dean in the head, attracting the hatred of the dean and the younger brother for a while, while Zhang Yang stepped aside and accelerated the reverse sprint!

As a result, he was stunned and passed by the dean and those little brothers, and he was not hurt!

With the help of this moment, Zhang Yang ran in the direction of the 5th floor, after all, the obstacle of the stairs had disappeared, and at this time, Chu Fan also went in the direction of the 4th floor, and as he ran, he switched out of the Nightmare Shotgun to attack the dean!

The dean was almost mad, chasing hard, and Chu Fan ran hard!

At this time, Zhang Yang had already come to the 5th floor and came to the front of the pile of props, and for a while, he was dazzled: "It's developed by !!!"

Chu Fan smiled: "Don't be a fool, pick it up, when will you install C4, tell me!"

"Huh!"

......

Chu Fan slipped these guys from the 5th floor to the 2nd floor, and then began to run upwards, because the distance had not been widened, so the pursuers behind him were always there.

And after Zhang Yang picked up the treasures on the 5th floor, he immediately came to the side of the broken road, and shouted while placing C4: "Brother, I'm safe!!"

Chu Fan said: "Wait!"

"Hmm!" Zhang Yang canceled the laying.

Chu Fan used his amazing mental arithmetic ability to calculate as he ran, and finally, he nodded: "An!"

Zhang Yang immediately placed it!

Because the zombies had slipped away, Chu Fan had already come to the passage to the 5th floor, and behind him, the boss and a group of small dots were with him.

Chu Fan's previous position was really amazing, so that the distance between the little ones and the boss was never opened, so soon, these little little points followed Chu Fan to the 5th floor, close to the side of the broken road, at this time, Zhang Yang was already waiting for him here, seeing him coming, without saying a word, he followed him and jumped down from the broken road!

Subsequently, the two of them fell from the 5th floor to the 4th floor, and their HP was bruised by more than 10 points, but it really didn't matter!

Then, the two of them jumped again, jumping directly to the third floor and a half, followed by a desperate run!

While they were doing these actions, the boss and those little minions were stunned for a while, and then, the boss woke up first, but before he could run back, he heard a deafening explosion!

For a while, the entire main building shook, and the surrounding zombie elites were all shattered by the violent explosion, and they were all wiped out, and the boss was no better, with a full 3 million HP being defeated!

And when Chu Fan and Zhang Yang landed, no one showed a smug look, because they knew very well that this plan was only a third of the way through, and the next step was to kill the boss before the corpses rushed up!
