"Squeak." With a bang, the security door slowly opened, and a smell full of musty and rancid smell was carried into the room by the air current, and the four people on the smoked floor couldn't help but feel a little nauseated.

Ning Xu frowned slightly, stretched out his hand and swung out a flame suspended in front of him to drive away the rancid smell, and then reached out and held it in the air, drawing a gorgeous long sword surrounded by flames.

The flames on the phoenix feather sword were swirling, and on the palm of Ning Xu's hand holding the hilt, a crimson rune lit up, making the aura on his body even more powerful.

With the sharpness of the long sword in his hand, and the powerful power bestowed on him by the Fire Rune Cloud Interceptor, Ning Xu was confident that he could slash any dimensional creature with the strength to resist him with a single sword.

Although the First Emperor's Fist is as powerful, it can't always show everything in front of others, so you have to keep one or two back hands to prevent being overshadowed.

"Whew." Ning Xu exhaled softly, raised his feet and moved up in small steps, this is the second floor, and the whole house has more than a dozen floors.

The hallway was dusty, and it looked like the dust that had been deposited by no one to clean it for a long time.

Every time Ning Xu just moved a step slightly, there would be puffs of dust flying up in the air, if it weren't for the energy shield on his body, I am afraid that this dust alone would choke a few people uncomfortable.

The flames spread from Ning Xu's body, quickly burning the clumps of dust, and in the corridor that had been abandoned for many years, the four of them walked cautiously.

Just after Ning Xu turned a corner, a gust of fishy wind blew in his face. It was a giant dog covered in messy hair, and as soon as he saw a few people, he pounced directly.

The giant dog didn't know if it was because he had eaten too much carrion, and there was a rancid smell in the huge mouth, which was a little disgusting.

Ning Xu didn't dodge or dodge, the long sword in his hand was raised, and he resigned directly into its mouth, as if it was going to directly pierce the entire body of the monster.

The three people who followed closely behind also reacted immediately, and the blue light flashed in the hands of the dark night, and a blue light mask also appeared on Ning Xu's body.

And in Luca's hand, a silver-white spear completely condensed by electric light flew out and smashed into the demon dog, instantly turning into a ball of electricity, completely enveloping the demon dog's body in it.

In the lightning, the demon dog roared angrily, but the muscles all over his body were paralyzed by the electricity, and he couldn't move for a while.

The all-white pistol appeared in Gu Ran's palm, and after the muzzle was aimed at the demon dog's head, a red light erupted, turning into a red bullet and blasting towards the demon dog's head.

"Bang." With a bang, the head of the demon dog exploded in an instant, and the red and white scattered all over the ground, that is, Ning Xu had a frost shield to protect himself, otherwise he would have to be splashed all over his body by those things.

Flames burst forth, incinerating all the filth that had been sprinkled on the frost shield.

After the death of the demon dog, it seemed that there was no second monster in the entire building, and Ning Xu's soul power erupted, and under the detection of the soul power, several people seemed to have turned into phantoms, and rushed upstairs.

"Smack." With a bang, Ning Xu stretched out his hand and pushed open the iron door of the rooftop, and the long sword in his hand flew up in the air, quickly patrolling back and forth in the entire rooftop, eliminating possible dangers.

"It's safe, you can go up." Ning Xu whispered behind him and rushed into the rooftop first.

The rooftop was very empty, and from the rooftop, you could see the tall buildings everywhere, one after another hideous-looking dimensional beasts were constantly walking up and down the street below, and there was no sign of leaving.

In the dark night, Gu Ran and the others followed into the rooftop, and Luca, who followed closely, walked into the rooftop and closed the iron door again.

Then he summoned his shield and leaned against the door, completely sealing the door, even if a knight-level dimensional beast wanted to break through the iron door with a shield, it would be very difficult.

That little time was enough for the four of them to react to the enemy.

"It's hard to go back." Ning Xu took the binoculars and scanned the surrounding buildings, this building was not too tall, and the buildings next to it were much higher than this building, which meant that it would be more difficult than they imagined to think of other rooftops.

This building is two blocks away from the hotel, and if you want to rush from the roof, you need to at least use your flying sword to build a few pedals that can be used to accelerate, otherwise even a professional will jump halfway and fall straight down.

And if you fall into the herd, the price is only one word, and that is death!

If he had a hook in his hand, it would be different, and with the strong physical fitness of a professional and the length of the hook, he could completely move between buildings.

It's just that I don't have it on hand, no.

Ning Xu suddenly remembered, maybe he really had that thing in his hand, but everyone in the awakening space was equipped with this thing, and then the whole bag was put into the space props by him

And the hook was naturally included in it.

With a thought, the entire backpack appeared directly in Ning Xu's hand, and after unzipping it, the metallic-colored hook was lying firmly at the bottom of the backpack.

"Whew, it's good to have this thing here."

Ning Xu let out a sigh of relief, and after snapping the arm guard that fired the hook claw onto his arm, making sure that he could press the trigger at any time to launch the hook claw, he turned his head to look at the three people behind him.

All three of them kept looking around with binoculars, as if trying to find a way back to the hotel.

"Ahem."

Ning Xu coughed a few times, attracting the attention of several people, and raised the hook in his hand and said.

"I'll make pedals out of my flying sword, and then when I reach a certain height, I'll launch a hook to get to the roof of this building."

As he spoke, he lifted his finger and pointed to the towering building in front of him.

"Ah, Grappling."

The moment they saw the thing in Ning Xu's hand, several people's eyes lit up, and they all seemed to know the usefulness of this thing.

"You choose someone to go first, my palace is behind, so that even if any of you makes a mistake, I can save him in time, who comes, say in advance, there may be monsters on the opposite rooftop, and the first person to go up will be responsible for cleaning up."

"After cleaning up the monsters, throw the hook back, and then the other person will go up again, and whoever will come first."

The three of them looked at each other for a moment, and they were all a little hesitant in their hearts, the first person to go up must have a very heavy responsibility on his shoulders, so no one dared to take this job rashly.
