"You're here?"

"Well," Richard replied in a low voice, suddenly feeling a little confused, as if he had forgotten all the things that had just been in the old lame man's bar when he was communicating with others, "I'm sorry, I'm late, and something was delayed......"

"It's okay," to Richard's surprise, Zhan Qinghan shook his head indifferently, put the stack of books in his arms on the table, and sat down again to leave a free seat next to him.

She stretched out her hand to pull up the disobedient hair that fell to her ears, and hurriedly said while opening the book, "There are only ten minutes left, and the talk will definitely not be finished, you can take these books back and take a look at them first, the ones marked with a red pen must be read, and the others can be roughly browsed." ”

"In addition, I will use a blue pen to re-outline a few key points for you, which we will talk about tomorrow......" Zhan Qinghan said, took out a pen and sketched some places on the page, and then closed the book again and looked up at Richard.

"What's on my face?" She looked strangely at Richard, who was staring at her in a daze.

"Huh? No! In the blink of an eye, Richard broke free from some unknown emotion and smiled at the girl, "You're leaving now?" ”

"Well, I'll leave the book here, you remember to clean it and take it back to read." Zhan Qinghan patiently reminded Richard, "Don't forget." ”

Richard nodded, "Then I'll send you down......"

……

The wind blew in the middle of the night, and the cold crept through the gap in his collar into Richard's body, and the sudden cold made the latter sober up a little. When he looked down the path again, there was no girl's back......

Back in the library, the last few late-night students also packed up their books and walked downstairs, and the library on the 7th floor suddenly became empty, so quiet that Richard could clearly hear his footsteps echoing between the four walls of the library.

Coming to the top floor, Richard looked very funny with a mop in one hand and a broom in the other, and there was a bucket of water next to him, soaked in a rag.

"1000 square meters ......"

Richard couldn't help but have a headache when he looked at the empty floor, although he always knew what the concept of 1,000 square meters was, but it was only when you really faced such a 1,000 square meters that Richard suddenly realized that this was really a large area...... It's always a little bigger than I expected, and the bookcase seems to be more than I saw at a quick glance before.

I don't know if someone is deliberately playing tricks on him, Richard searched the library and found no automatic cleaning machine, not even a machine that can be modified, except for books or books, so Richard can only clean these 7 floors in the most primitive way: using a broom, a mop, and a rag.

He rolled up his sleeves and lowered them to his elbows, wet the mop in the bucket and then lifted it up, watching the dripping water dripping off the mop, he suddenly felt weak.

……

It took Richard a full two hours to get from the seventh floor to the third floor, which was already his maximum speed, and he was even forced to use the ice force in a frenzy, one hand stretched out to urge the ice force to spread like mist and spread throughout the entire floor, and then turned into small raindrops in mid-air and fell on the floor, helping Richard clean the ground.

He's almost going crazy now, I really don't know if he wouldn't be on the 7th layer if he didn't have the help of the Ice Force, right?

As for the new use of the newly unearthed Ice Force, Richard could only smile wryly and shake his head, sure enough, practice is the source of innovation, and the Ice Force used to kill people can now not only "ice weld" steel but also mop the floor!

…….

Another hour had passed, and the long dark night always tortured sleepless people to death, and Richard's eyes were red and sleepy, and it was already past 1 o'clock in the morning, and the lights of the buildings in the academy had long since been extinguished, leaving only the library, which was extraordinarily brilliant in the long lonely night, radiating a soft light in the loneliness.

Of course, there was another person who was as lonely and complaining in the dark as the library: Richard, who was wiping the table, threw the rag into the bucket, and Richard fell to the ground as if he had collapsed, he really didn't expect that it would take so much time to clean a library.

Gasping for breath, Richard was so tired that he didn't even bother to pick up the mop that he accidentally touched next to him, but leaned his head against the corner of his chair, squinting as if he was taking a nap.

"Tick, tick"

The sound of dripping water sounded from Richard's side, and he looked helplessly at the mop lying on the ground next to him and the bucket next to him, only to find that the dripping sound was not coming from there.

Close your eyes to extend your hearing, and the darkness of vision seems to sharpen your hearing. It was then that Richard slowly realized that the ticking sound was not coherent, but more like two voices with short intervals.

"Tick, tick, tick, tick"

What is this sound......

Richard opened his eyes and stood up suspiciously, looking to the left and right, the neatly arranged chairs quietly, as if hiding something. And when he tried to listen to the ticking sound again, he couldn't hear it anymore, as if the sudden dripping sound was just his hallucination.

The sense of vigilance was turned up to the maximum by Richard, and the sleepiness disappeared in an instant, and he dragged a little heavy steps back and forth on the first floor of the library twice, but still did not hear the strange voice again.

Maybe it's a hole in the water pipe in the floor......

Richard tried to convince himself but became more and more suspicious, but when he looked up, the clock hanging on the wall silently reminded him that it was already 2 o'clock in the morning.

There was still morning class, and Richard didn't want to drag his tired body to the class, not to mention that his whole body was numb with muscle tissue, as if telling him that it was time to sleep.

Glancing back at the empty and lonely library, the days to come are long, he thought.

The lights on the last floor were extinguished, the boy locked the door of the library, and the latter took a solemn look at the lonely building in the night wind, put on a hat to cover his face, and Richard slowly left the library with his hands in his trouser pockets.

And after the boy left the library, at a certain moment in the quiet library, it seemed that the sound of "ticking, ticking" began to be heard again, and the sound echoed in the empty floor.

It's weird.
