The circuitry on this floor was extremely old, and the lights flickered, but Serina didn't care about this place, but continued to climb to the top floor, because the windows here were covered by lush vines and leaves, and without the intervention of the moonlight, the light was even more dim than downstairs.

Serina went inside and closed the window near the outside room, not only the light, but also the heat of the lamp would draw the monsters in.

After extinguishing all the lights on one side in quick succession, Sirina suddenly felt something flash behind her, and when she looked back, there was nothing but darkness. She let out a sigh, rubbed her eyes, and walked down nonchalantly.

"I'm probably too tired lately, let's take a good rest today~"

Arriving on the twenty-first floor, she felt more and more that something was wrong, so she quickened her pace and strode around the corner of the corridor.

"What the hell does this feel like?"

Continuously looking back and not being able to see anything behind him, other people won't do such boring things, is it really the illusion that I didn't have enough rest?

Sirina summoned obsidian, clipped a charm in her hand, and slowly walked towards the dark staircase.

"Who's there?" she whispered, as she tentatively threw the spell out, which sparked in the air, and she carefully controlled the scope of the explosion, only to explode a small cloud of fireworks before disappearing into midair.

The fire didn't shine anything, it was surprisingly quiet, there was no sound, and she could almost hear her own heartbeat.

"Sure enough, it's just a hallucination...... Forget it, turn off the lights and go back. ”

"Whew-"

"Huh?" In a trance, Serina suddenly felt that her body had become slimy, and her arms were tightly attached to the sides of her body and she couldn't break away, as if she was wrapped in a ball of hot meat, "What?!"

Sirina lowered her head and looked at it, and what was lying on her body was actually a ball of soft meat butterflies! A pair of wide meat wings were wrapping her upper body, and there was a slight pain from her back, it was tearing at her body!

"Get out of here!" Sirina couldn't pull her hands out, so she slammed it into the corners of the wall.

"Squeak-" Meat Butterfly screamed, but still chattered around Sirina's body.

It didn't bite very hard, it didn't seem like it had eaten for a long time, and the strength of its teeth was very small, but the strength of the wings was so strong that no matter how hard she struggled, she couldn't get out.

"It's no wonder I'm not going to blame!" Sirina twisted her body so that her right hand reached a spell on the side of her body, judging from the perception of power, it should be an explosion charm, but if the explosion charm exploded here, not only this monster, but also herself would be injured, so the power and scope of the explosion must be controlled extremely accurately.

"......"

The black spell began to glow, and Sirina tossed the spell away, letting it slide down to her thigh.

"Bang!" blood and fire burst out, Serina's thigh was wounded, and bright red blood flowed out, and the meat butterfly was also startled by the explosion, flapping its wings and flying aside, a pair of green eyes staring directly at the prey in front of her.

"Take me again. Serina touched the black box on her waist, but found that there was not much of the charm left, part of it had been used up in today's battle, and many more were destroyed in the explosion just now, and the rest was all stained with the slime of the meat butterfly, completely useless!

"Damn, is there only one left that works?" Silina rummaged through the obsidian, and only found an emergency charm in the last mezzanine, only slightly wrinkled, which did not affect the power of the explosion, but was afraid that the sound of the explosion would attract something outside.

"Whew-"

The butterflies pounced ferociously, their sharp teeth frantically biting into Sirina's body.

She deftly dodged the monster's attack, timing it and throwing the charm in her hand into its mouth.

After chewing it twice, Meat Butterfly realized that the taste was wrong, and immediately spit out the charm, and the blasting charm flew in the air for a long distance, and the effect was delayed for a long time before it took effect.

"Boom-"

Sakurama was awakened by the sound of the explosion, and Shinomiya, who was also with him, was also surprised, looking upstairs in surprise.

"Where's Sirina?" Sakuruma looked around, Mu Fengye hadn't come back yet, and Sirina was nowhere to be seen.

"Aini-san, let's go up there, let's hurry up and have a look, if you don't encounter a monster, you can't use obsidian. "Shinomiya anxiously ran up the stairs with Sakurama, the clutter that Fujiwara had piled up here a few years ago had been removed, and there were many traces of water and broken fences on the iron gate, probably caused by Sirina's ice charm.

"Something must have happened to her. ”

The shockwave of the explosion shook Sirina to the side, but the thick-skinned monster was not hurt much.

With her last weapons gone, and no leaves left for supplies, she hurried to the end of the hallway, where she grabbed a rotten chair and slammed it down on Butterfly!

The chair exploded in all directions, and the slime of the Butterflies suddenly stepped on her feet, and the whole person fell on her back, and just as she was helpless, an arrow shot out of the Butterflies's mouth, severing the nerves connected to the brain.

"Whew...... ...... "Silina looked at the meat butterfly on the ground in shock, and her body was already embarrassed.

"Sirina, are you alright?" Sakuruma hurried over and pulled Sakuruma up from the ground after confirming that the Meat Butterfly was dead.

"It's okay, I just got a bite from it. Serena turned, a mess of wounds flushing.

"This is the guy who was locked up here by Fujiwara three years ago, and I didn't expect to be hungry for so long and still be alive. Sakuruma knew the appearance of this thing, and it was the same species as the one who attacked Yang Xiaokai that day, with a pattern like a human face on its body, and other meat butterflies rarely had this kind of symbol, "If it hadn't been hungry for so long, you might have died just now." ”

"Didn't that guy say he had already inspected the top floor......" Serina said indignantly.

"Fortunately, we have a bathroom in our room, so let's go wash the dirty things on our bodies first." Sakurama looked around for a moment, then walked up to another floor and looked at the door of the rooftop with the help of the light of the blue dragon scales, there were no more creatures here except for the dead meat butterflies, and the building was completely safe now.

After turning off the lights on the twenty-first and twentieth floors, Sakurama Sirina and Shinomiya returned to their stronghold.

As soon as she got around the corner, she bumped into Chigusa who was hurrying in a hurry, and the slime on Serina's body wiped her all over.

"Chigusa, why did you get up?"

Chigusa looked at the mucus on her body with disgust and said, "Mu Feng said that he heard the sound of an explosion above, so let me come up and take a look, are you all right?"

"The monster is dead. Serina asked wryly, "Have you really checked it?"

Chigusa avoided Sirina's gaze with an embarrassed face, and whispered, "We saw that the twentieth floor was locked up, so we didn't go over to patrol, sorry ......"

"Forget it, let's go take a shower together. Serina sighed, she couldn't get angry at Chigusa, and with the situation at the time, even she wouldn't bother to go up to the top floor to find out.

Late at night, Sakurama, who had taken a nap before, had a little energy. She slowly got up from the bed, carefully not waking Chigusa and Shinomiya, who were sleeping on the side, and came to the window alone.

Peeling back the leaves in front of the window, there are many creatures wandering under the building, and their breath can be felt from a distance.

The wind was cool at night, and Sakurama subconsciously rubbed her arms and closed the window.

Flipping through the backpack in the corner, she took out the two photos she found during the day, and when she saw the people on it, she had mixed feelings in her heart, and she would never have dreamed that in the end, only herself, the most useless guy, survived.

"Ahh Probably the wind just woke up Gao Zhi, who has always been unable to wake up from the earthquake, he will be woken up by a gust of wind, he sat up, rubbed his eyes and looked at the cherry blossoms standing at the window, his mouth was dry, hooked the kettle on the table and drank a few sips after suddenly feeling refreshed, completely sleepless.

"Are these your friends?" he asked, walking behind Sakurama.

"Well, these two are the Hades couple, as well as my younger brother Yang Xiaokai. This ......" Sakurama saw Natsujo and didn't know how to describe her relationship with herself, she couldn't tell whether it was a friend or an enemy, and for a moment she didn't even know why she appeared in her photo.

"Xia Cheng, I've heard you mention it before, and I can't forget it until now?"

"I was the one who made her like that, and if it weren't for me, it wouldn't be all this. Sakurama regretted.

But Gao Zhi didn't think so, and said sharply: "Then we won't be able to meet you, to be honest, from the beginning I have been doubting you every day, thinking that you have other plans for us, although this is the case, but you have been desperately protecting the people around you." Without you, we wouldn't have been here, and we wouldn't have known that there was an even bigger trap behind this game. You are the most important character, and if even you say that you are so depressed, there will be no one to save other lives. ”

Sakurama looked at Gao Zhi in surprise, he had never said such earth-shattering words as today, that is, at this second, Sakurama's impression of him completely changed, just as Mu Fengye said, he was a trustworthy person.

"No wonder Mu Feng trusts you so much, I wrote down what you said to me. ”

"Why do you say such things all of a sudden...... You're not going to do anything, are you?" Takashi took two steps back, unsure if something had provoked Sakuruma.

"Rest assured, we still have a lot of things to do, let's go ahead and look for the next Heavenly Tree after resting here for two days and recuperating. Sakuruma put the photos away, there was nothing more important than these two photos now, it was the only memory, and she had to protect this precious thing.
