For Cao Yue and Butterfly, Ding Lan has strong self-confidence.

Of course, the two did not "live up" to Ding Lan's expectations, attacking very quickly and not encountering strong blockades.

In less than ten minutes, they were able to solve a total of six gangsters on five floors.

On each floor, there are one or more gangsters, hidden dark places.

They had already reached the eighth floor.

Cao Yue made a gesture to the butterfly asking for cover, and the butterfly understood, leaned out, and fired a shuttle of bullets in the direction where the gangster might be hiding. Cao Yue took advantage of the cover of butterflies to jump onto the railing of the corridor, and with another hook of his hand, a somersault jumped directly to the corridor on the ninth floor.

A gangster, who was hiding behind a pillar and pointed a gun at the stairs, was killed instantly after being hit by a bullet.

If someone else saw Cao Yue's action just now, their jaws would definitely drop in shock. Jump onto the railing in the hallway, jump up at the railing that is only a few centimeters wide, grab the railing of the previous floor, and use the traction of your arm strength to go straight up.

This courage, this strength, this agility, few people can achieve it.

You must know that this floor is at least twenty meters above the ground, and if he sits on the air with one foot, or slips during the action, and can't grasp the railing above, he is likely to fall directly to the first floor. If you fall down more than 20 meters, you will be seriously injured if you don't die.

You must know that the width of the railing is less than ten centimeters, and for the sake of beauty, it is made into a semicircle, and even if the average person stands on something, he may not stand firmly. The railing is also about three meters high from the previous floor, and no one dares to think that they can go upstairs in such a way.

But in the eyes of butterflies, it is very common for Cao Yue to make such an action, there is no fuss at all, and he often does more thrilling and exciting actions than this.

After Cao Yue's attack was successful, Butterfly took the opportunity to rush up the stairs to the eighth floor.

When Butterfly rushed to the eighth floor, he raised his hand and shot a gangster on the ninth floor.

A 47 rifle and the gangster's body fell from the vertical space in the middle of the corridor to the first floor at the same time, making a loud noise.

The structure of the tenth floor and the ninth floor is different, the staircase in the middle of the first to the ninth floor is spiraled up, and a huge space in the middle goes directly from the first floor to the ninth floor, and after reaching the ninth floor, the roof of the ninth floor covers the huge gap in the middle of the corridor.

That is to say, from the ninth floor to the tenth floor, attacking upwards, you can only pass through the corridor.

There are definitely more gangsters lurking above than on the floors below.

The police briefing did not contain a specific number of culprits. The two of them attacked along the way, and they had already eliminated many gangsters, and they didn't know how many more. However, one thing that reassures Cao Yue is that the combat ability of these mercenaries is not very good, and depending on the situation, they are not very rich in combat experience, so they may be newcomers who have just been recruited.

Battle-hardened mercenaries are not so easy to deal with.

But Cao Yue also knew that the real test was coming. The strongest and most elite of the gangsters will definitely appear in the back.

After solving the gangsters on the ninth floor, Butterfly took the lead, raised his gun and bent down to slowly sneak to the staircase near the tenth floor, and then threw a tear gas canister very simply. When there were a few violent coughs immediately, Cao Yue, who was following behind the butterfly, immediately flashed forward, kicked open the fire door, raised his gun and shot fiercely, and then rolled behind the pillar at a very fast speed.

This was followed by several bursts of fire, hiding a gangster near the corridor, who was quickly killed.

After receiving the safety tips from Cao Yue, the butterfly also quickly rushed to the tenth floor.

Then the two alternated runs, killing two more gangsters.

The remaining two gangsters seemed to have given up resistance and retreated to the eleventh floor.

The eleventh and twelfth floors must be the places where the gangsters are most intensively guarded, Cao Yue pointed to the bathroom not far from the stairs and gestured to the butterfly. The butterfly understood, and immediately rushed forward, raised her gun and shot at the staircase where the gangsters had retreated just now, draining a magazine of bullets, and making a gesture of preparing for a strong attack.

And Cao Yue took advantage of the butterfly shooting and dodged into the bathroom.

He crouched near the bathroom window, and after checking the upstairs and downstairs carefully, he put on his equipment, leaned over and climbed to the bathroom window, ready to go directly upstairs through the window.

When Cao Yue stood on the window, the people downstairs all saw a figure leaning out of the window.

The telescopes immediately held up their binoculars to check the situation, and those who had scopes in their rifles immediately pointed their scopes at this person.

"It's the young master" Ding Lan held the binoculars, looked at it, and whispered to Nie Dan: "They are going well, and they are ready to storm the twelfth floor." ”

Nie Dan, who had always been worried, took the telescope beside him without saying a word to check the situation.

In the telescope, Cao Yue stood in the air, and then kicked hard, and the whole person rose into the air, grabbing the windowsill of the bathroom on the upper floor with both hands. Soon, the whole person went up, and then the figure disappeared.

When he saw Cao Yue jumping up, the strength of Nie Dan's body seemed to be hollowed out, and he could only stand on the table next to him.

How could he be like this? How could this be like this? Is this guy crazy? More than a dozen stories high, more than 30 meters away, without any protective measures, when gangsters appear nearby at any time, this guy actually climbed from the window to the upper floor with his bare hands.

What if your foot slips, or if you accidentally miss it and a gangster suddenly appears?

At any mistake, Cao Yue could fall from a tall building and lose his life.

She didn't know what thrilling adventures Cao Yue had experienced before, and maybe there were more heart-wrenching scenes than today, but she didn't see it with her own eyes, so she wasn't so scared. Today, just now, she held the binoculars and saw Cao Yue jumping to the upper floor in this way, which really frightened her, she felt that her heart was in severe pain, it was difficult to breathe, she couldn't stand still, she was about to collapse.

Ding Lan, who was beside her, had been observing Nie Dan's movements, and when she saw that Nie Dan's face was pale and her body was a little shaky, she immediately came over to support her and whispered comfort.

It didn't take long for another figure to appear on a window on the eleventh floor, and Cao Yue jumped from the eleventh floor to the twelfth-floor windowsill with the same movement, and drilled into it at a very fast speed, and the figure disappeared in an instant.

It's just that this time he didn't climb through the bathroom window.

He had already eliminated all the gangsters on the eleventh floor, and the difficulty of attacking the gangsters from behind had been reduced a lot. The butterfly that feinted to attack also went up to the eleventh floor under Cao Yue's response.

And Cao Yue was supported by butterflies, and then went up to the twelfth floor in a similar way.

However, Nie Dan didn't see Cao Yue go upstairs again, and she was too fragile to look at it again.
