"Woohoohoo————"

An eerie cold wind echoed through the tower, and only a little sunlight shone in the dim cloister.

As soon as they came in, Zhao Lei and Fei Xiaoliu felt a chill down their spines, it turned out that only the location of the door had a little poor visibility, and they could barely see their fingers when they walked inside, and the oil lamp that was originally hanging on the wall next to the stairs had already dried up, even if there was a fire, it couldn't be lit.

Fei Xiaoliu subconsciously tugged at the corner of Zhao Lei's clothes, and suddenly she felt that she should stay below with the fifth brother.

The dark steps can only be slowly groped step by step, and the blind spot at the corner of the spiraling stairs is huge, and I don't know what monsters will rush out in the next moment.

The solemn atmosphere made Zhao Lei a little nervous, and a gust of bone-piercing cool breeze blew, making Zhao Lei a little out of breath, and it took a while to forcibly calm down, Zhao Lei communicated with Xiao Liu, and then continued to capture the information fed back by the wind element.

Closing his eyes, Zhao Lei's mind formed a rough outline map of the corridor, the distribution of the wind element was clearly visible, Zhao Lei seemed to be wearing a night vision device, and now, the wind is Zhao Lei's eyes!

In the dim corner, countless pairs of glasses stared at the two people who broke into the tower,

"Squeak Squeak————"

The piercing sound was like hundreds of blades cutting through the glass, tearing at Zhao Lei and Fei Xiaoliu's eardrums, this sound seemed to have a demonic nature, directly destroying the spiritual power of the two, making the brains of the two as painful as pins and needles.

Zhao Lei was still talking to Xiao Liu with a spiritual link, but he was interrupted before he could think of it, so he had to talk honestly: "Xiao Liu, advance or retreat?"

Xiao Liu, who was hiding behind Zhao Lei, covered his ears and opened his mouth in pain: "Don't be too loud, this is a sickle-winged ghost bat!"

"Sickle-winged ghost bat?" Zhao Lei searched hard for the encyclopedia of alien beasts he had seen, and recalled this creature.

Sickle-winged ghost bats are the weakest but most fearsome of the beasts, feeding on the flesh and blood of creatures, usually in groups during the silent night.

Sucking blood while the prey is asleep, if you are lucky to be killed by the sickle-winged ghost bats when you sleep at night, it will be sucked into dry corpses in less than a minute, and the most terrifying thing is that the sickle-winged ghost bats will inject super strong anesthetics into the prey when sucking blood, until they become a pile of white bones without knowing it.

"Let's be quiet, it shouldn't be okay. Fei Xiaoliu calmed down and said to Zhao Lei.

"Aren't bats going to hibernate?" Zhao Lei asked in horror.

Fei Xiaoliu looked at the structure in the tower and said: "It is precisely because they are still hibernating, so we are still standing here well, if we encounter a group of ghost bats that are really hungry, we will inevitably have a fierce battle." ”

And it's not night yet, it's just that Zhao Lei and Xiao Liu broke into the sickle-winged ghost bat's lair, and the two of them disturbed their dreams with small movements, plus the bat's hibernation habit, they are just afraid of the cold and too lazy to move now.

"Hey, the sickle-winged ghost bat is also a fierce beast. Zhao Lei patted his head and said suddenly.

"Our first priority is to recover the detectors! "Fei Xiaoliu didn't want to die with Zhao Lei, and he didn't want to die for a little money.

"Alas~~ It's a pity. Zhao Lei shrugged.

"Don't make any bad decisions, judging by the sound just now, there are definitely more than thirty sickle-winged ghost bats in this tower, and in less than five seconds of fighting in such a small place, we will be twisted to pieces by their steel-boned sickle wings. Fei Xiaoliu was not worried about Zhao Lei, and explained to him the seriousness of the matter.

Zhao Lei honestly continued to pull Xiao Liu to tiptoe up.

"Why do you say there are so many sickle-winged ghost bats in this kind of place? Shouldn't they migrate to the south for the winter?" Zhao Lei was a little puzzled, it stands to reason that flying creatures generally choose to fly to the south if they spend the winter, this is the wisest choice, but a large group of bats and turtles huddle in Xicheng District for the winter, which is very unreasonable.

Fei Xiaoliu followed the stairs and thought at the same time, the question asked by Zhao Lei is indeed worth pondering.

"To be able to feed more than thirty sickle-winged ghost bats for the winter, how much flesh does this need? At least ten beasts of the size of an adult three-eyed cat demon must be buried in the belly of the ghost bat, which also reflects how dense the fierce beasts are in the western district. Fei Xiaoliu said solemnly.

Zhao Lei also strengthened his vigilance a little, Xiao Liu actually said so, which means that this is not sensational, but a very reasonable speculation, this West District is more dangerous than they imagined, which also confirms that retrieving the detector is a wise move.

Originally, I thought that the abandoned West Side was only slightly out of control, but according to the information obtained now, the degree of loss of control has reached an unimaginable level.

Xiao Liu and Zhao Lei, who were marching in the dark, had unprecedentedly solemn expressions at the moment, when the number of fierce beasts exceeded a certain threshold value, the protection line could not withstand the huge pressure, and it would naturally evolve into a disaster at that time.

The western district borders the central city, although the central city still has the strongest defense line, but there is no city wall to block it, and the protective line is invisible, which means that the beast and the human are equivalent to a layer of glass, even if it is safe, it will cause unnecessary panic.

The most important thing is that the South District and the North District are also next to the West District, and the South District is Zhao Lei's home, and it is also the least safe place except for the West District, most of the residents in the South District are low-class people, so the energy of the security line will not be as sufficient as the North District, where the rich gather, and the most affected area will definitely be the South District.

Zhao Lei never thought that he would pick up such a big burden so soon, and he never thought that his task would suddenly change from simply making money to protecting his family.

Zhao Lei cheered up and continued to move forward cautiously.

The thirty-meter-high staircase is extraordinarily long, and the occasional bat cries make the atmosphere even more tense, and now Xiao Liu and Zhao Lei are afraid that this group of half-asleep guys will suddenly burst out, and the entire staircase of the tower does not even have a window, and there is no chance to jump out of the window, so it can be said that there is really no way to escape.

"There's light!" Zhao Lei, who was walking in front, pulled Xiao Liu and said happily.

"Shhh...... The color of this light is not quite right. Fei Xiaoliu looked ahead and found that the light Zhao Lei said was actually red, and the shallow red light was reflected on the wall around the corner, flickering and disappearing.

Zhao Lei also frowned, although it was said that it was afternoon, but the sunset could not be so red.

"Be careful, it's not like normal light. Xiao Liu grabbed the corner of Zhao Lei's clothes, obviously a little nervous.

Zhao Lei also awakened the wind element, ready to fight at any time.

"Da-da-da-da"

The sound of soft footsteps broke the silence in the tower, and the two of them walked towards the top of the tower step by step.

........

........

"Xiao Qi, Zhao Lei and Xiao Liu's connection was suddenly broken...... Do you think they will hang up......" Fei Wu, who was hiding under the tower at the moment, was holding a little black cat uneasily, and his nervous hands kept making some kind of up and down movement.

As the sun set, the dark night had begun to eat away at the eastern sky, and a few stars had poked their heads out, blinking their eyes in a flash, as if mocking the timid Fei Wu.

The orange blood sun was projected on the watchtower square, Fei Wu and Xiaoqi, who were nestled by the wall, quietly hid in the shadows on the east side of the watchtower, and behind the thirty-meter-high watchtower, the black shadow was stretched for a long time, spreading towards the eastern land, passing through the shops on the roadside, and through countless houses, extending the darkness to the central city......

"Meow~~" Xiao Qi, who was napping in Fei Wu's arms with his eyes closed, suddenly raised his head and shouted towards the house in the distance.

"What's the matter, Xiao Qi......" Fei Wu was frightened, Zhao Lei and Xiao Liu had lost contact, and he could only wait for the two of them who were uncertain before nightfall with Xiao Qi, but he almost forgot that it was also dangerous outside the tower!

Fei Wu hurriedly established a spiritual link with Xiao Qi to communicate with it.

Xiao Qi raised his little white paw and pointed to the dilapidated house in the distance, "It seems that there was a malicious gaze looking over there just now~"

"That means we're being targeted? Xiao Qi, you have to protect me! I buy you dried fish every day!" Fei Wu was scared and hurriedly hugged Xiao Qi's cat thigh.
