The flames gradually dissipated, and Shen Hao broke out of a large pile of charred corpse ashes, the armor on his body emitting a trace of heat in the heat.

"Fifteen USBMs, and one of them is an apostle...... This is the first isolation door. Putting down the blackened battle axe and round shield in his hand, Shen Hao sat down against the foot of the wall, raised his visor, and spewed out a puff of smoke and dust from his mouth.

Sakura looked at the fuel canister of the flamethrower on her back and said with a wry smile: "It's already consumed by a third, and if we continue like this, I'm afraid we won't even be able to pass through the fifty floors." ”

"Now that it's certain that the living are moving to the upper floors, let's not waste time on the floors below." Shen Hao stretched out his hand to touch the cigarette in his arms, but when he rushed into the fire with those USBMs in his arms before, the flammable items on his body had already burned out, and the old-fashioned appearance of the two people didn't look like they would carry cigarettes with them, so he could only smash his mouth and give up.

"Let's go up to the 80th floor first, and then decide whether it should go up or down according to the situation there." Shen Hao pouted.

"If you don't want to alarm those USBMs, it's not so easy to go upstairs, right?" Sakura wiped the beads of sweat from her head and responded, "Not only are they active in various rooms, but there are also a lot of hidden in the corridors and corridors and even in the bathroom. No matter how cautious we are, there is always some movement when we break down the isolation door, which will only attract more attention from the USBM. ”

"The isolation door is actually just a safe passage, but if we want to go upstairs, we don't have to take that safe passage, right?" Shen Hao smiled and stretched out his hand to the elevator door opposite, "Isn't there a shortcut there?" ”

"Elevators? Do you mean to climb up the elevator shaft? Sakura of Saionji Temple was stunned for a moment, and immediately reacted. The building has long been out of power, and even if there is no power outage, the security isolation system has been activated here, so all elevators have also entered a state of deactivation, and if you want to use the elevator to go up and down, you can only climb all the way up from the maintenance ladder in the elevator shaft.

"No! The space in the elevator shaft is too narrow, and if we are besieged by a large number of USBMs inside, we don't even have room to maneuver, which is too dangerous! Ryuichi Kanzaki, who had been silent, immediately retorted.

Climbing the engineering ladder of nearly 300 meters with bare hands is indeed a big burden for ordinary people, but for hunters whose bodies have been strengthened many times by nightmares, physical strength is not a limiting factor for them.

The cross-sectional area of the elevator shaft here is no more than ten square meters, and only one USBM is needed on the way to block the entire passage tightly, and they must have their free hands to grasp the staircase railing, so the way to use it for confrontation is even more stretched, and the narrow staircase also limits the number of people who fight the enemy head-on, basically only the person in front can fight the other party at a time, and the two behind him can't help except staring, so choosing such a path is indeed a taboo for the Nightmare Hunters.

"I understand your scruples, but I have a different opinion." Shen Hao stood up, walked slowly to the elevator door, his fingers wrapped in metal gloves gently tapped the closed elevator door, and analyzed lightly, "First of all, this elevator shaft has entered a closed state since the emergency isolation system was activated, and it is impossible for people and animals to stay in it." So that is to say, all along, in addition to the track steel cable, there is only a ladder car in this elevator shaft, but these will not arouse the interest of those BMs, so I think ......"

When he said this, Shen Hao suddenly slammed the ten fingers of both hands into the crack in the elevator door, and then forcefully split to the left and right. only heard a "creak", and the elevator door was forcibly broken open a gap more than one person wide.

"So I think maybe the safest channel that isn't the one with USBM harassment is here." The dark elevator shaft was deep and there was no end in sight, and a cold cool breeze slowly blew out from the open elevator door, which lifted Shen Hao's spirits.

"How?" Shen Hao shook the tactical flashlight in his hand, and the white beam of light shone out of the metal staircase that slipped vertically upwards on the wall of the well.

Sakura of Saionji and Ryuichi Kanzaki on the side glanced at each other, and the former bit his lip and nodded.

......

"This is the fourth isolation door......" Looking at the heavy iron gate in front of her, which was still forcibly pierced by violence, Mo Chenyan was a little speechless.

"Not only that, have you noticed that the hole in this iron gate seems to be getting bigger and bigger?" Hakamata stood under the hole, using a flashlight to observe the edge of the hole, and he had paid special attention to the several isolation doors he had passed before. Although at a cursory glance, they are all holes that have been forcibly squeezed open, but some differences can still be seen in some details.

Especially this time, the cracks at the edges were much deeper than the previous door, and some of the cracks even extended all the way to the wall that fixed the door frame. In other words, the creature that opened the hole was barely squeezed out of the hole as it passed through it, and there was no sign of it at the initial hole, which proved a reality that all three of them were very reluctant to face—no matter what this guy was, it was getting bigger and bigger.

"There's one more thing to worry about." Hayato Tsumi, who was in charge of the broken floor, also followed at this time, he looked at the two people standing in front of the isolation door, and added, "The number of USBMs in these floors is also gradually decreasing, although we are trying to avoid these annoying things in a non-combat way, but I have to say that the USBM we encountered in the next thirty floors is actually not much more than the USBM we saw in the first ten floors, which can be seen from the fuel consumption we carry." With that, he shook the fuel canister on his back, and the pressure pointer on it was now pointing at 22%.

"USBM is different from the domestic BM, although it also has an excellent appetite and tenacious vitality, but the way they multiply is not to divide and reproduce, but to increase their own volume." Hakamata helped his glasses, "It seems that on the road ahead, there is a guy with a pretty good appetite who is heading up the upper echelons while hunting, and this guy is probably even his own kind in the recipe." ”

"They eat their own kind?" Mo Chenyan asked a little incredulously, if that's the case, just let them kill each other.

"Hehe, do you think it's a good thing for them to devour each other?" Hakamata smiled, "You should think of their behavior as gathering sand into a tower, twisting the scattered forces into one, no matter how you think about it, it's not easy to deal with, right?" ”

"There's nothing wrong with a big monster, and instead of facing a BM that's as dense as a cow's hair outside, I think it's actually more pleasant to deal with a whole enlarged USBM, at least once and for all, isn't it?" Mo Chenyan rested enough, so she continued to go upstairs with her weapon, and after getting used to the weight of this armor, her footsteps were relatively light. However, the metal heel always makes a soft "gurgling" sound when it touches the tiled staircase, so the two people covering in the rear will be separated from her by a short distance, allowing her to attract enemy sneak attacks in front.

"It turns out that the people who take the shield are all hard MT......" For this reason, Mo Chenyan has already complained.

"I agree with Miss Mo." Hayato rarely stood on Mo Chenyan's side and said, "Even if this 'big stomach king' grows to a few tons, but it gives us only one goal, everyone works together, as long as we kill it once, if we face those large numbers of BM, not only can we not concentrate fire to attack, but even if we miss one of them, it only needs to survive for dozens of minutes, and it can rush back with a large group of the same kind." ”

"Don't forget, the nightmare energy in our Nightmare Hunter's body is limited, and we are not afraid of attacking tough battles, what we are most afraid of is that kind of war of attrition."

"That's what I said......"

The three of them discussed in a whisper as they went up another floor, and after exiting the security door, their vision suddenly widened. It was supposed to be a large clothing store, but now there was nothing left of it except for the empty metal hangers on the floor, including the billboards on the beams. Even the wallpaper was scraped off.

"There are no enemies...... Not a single one! Hakamata closed his eyes and sensed it, there were very few obstacles here, and his mental sensing range and speed had increased a lot.

"Look at it, there will be no survivors like this......" Mo Chenyan whistled casually, and prepared to turn back. Now they have searched less than half of the floors, and the so-called long nights and dreams are many, and time is always precious.

Hayato and Hakamata Koo also turned around together, ready to go back to the stairwell, and the moment Hayato turned around, a faint sense of crisis suddenly came to his heart, although the brand on his chest still did not give a warning, but after getting used to the elusive abilities of these USBMs, he quickly believed in his sixth sense.

"It's a sneak attack! Note! He looked back and shouted, bowing like a fox around the corner. Almost at the same moment, a loud bang came from the ceiling above the trio's heads.

"Be careful!" A thick black shadow fell straight down towards Hakamata Xiaofu in the middle of the three like an ancient tree, and at this time, Mo Chenyan, who had just cut the guard from the forward, had already pounced for the first time. The distance between the two was less than two meters, but the black shadow that suddenly appeared was actually two points faster than the one who flew to rescue her.

Mo Chenyan was in a hurry, Hakamata Xiaofu was not like he was a body enhancer, and he had a full set of heavy armor to protect him. Look at his small body, if he is hit by this black shadow, he will definitely be dead or alive. In a hurry, he had already taken off the round shield in his left hand, shook his hand and flew out.
