The boy's home decoration is not exquisite or simple, and the shoes still have to be changed, so Gu Wencheng handed over two pairs of plain slippers.

Su Meng watched Liu Zhen choose first, Liu Zhen looked left and right, frowned and didn't say anything, picked one and put it on, and the blue girl behind her breathed a sigh of relief.

Except for the original solid wood dining table left by the landlord, most of the other furniture is pressed with boards, and the corners are slightly peeled and worn.

Except for the white light above the dining table, which was bright, the other ceiling lights were more or less dim, and the dust on the lampshade and the dark furniture added another layer of darkness. The room was filled with the smell of oil smoke and laundry detergent, the bathroom smelled of detergent, the sofa was covered with cloth pads, and the TV was covered with a white shield.

Gu Wencheng turned on the headlights in the living room, looked at the sofa and shook his head, looked at his mother's closed door, then looked at the dining table, and finally brought the girls into his room.

Gu Wencheng's room is a different scene, on the left is a two-meter-four dark wooden table, on which is a large blue display screen and a buzzing chassis, the sound emits a slight melody, a small lamp on the bedside table facing the door, and a wardrobe that occupies the wall on the left hand side of the door.

Unlike the imaginary otaku, the room is clean and tidy, the books are neat and orderly, and there is not much clutter, which makes Ryu Zhen's eyes widen.

The windows are ajar, and the air in the room is much fresher than outside.

There were no strange girls on the wall, or posters of weapon stars or the like, and the glass teacup on the table and the green tea inside attracted Liu Zhen's attention, and she nodded lightly at the teacup.

The melody of a piano sonata came from the speakers, like leaves drifting between the wind and rain and the river, drifting farther and farther.

"Beethoven No. 17."

The lips under the red messy bangs whispered, and the corners of the mouth were gently raised.

"Well, it's the playlist that went down, I used to like to listen to it, Liu Zhen, do you like classics too."

"I don't like it that much, I just like Pollini." Ryu Jin walked into the table and leaned down to look at the playback software on the screen.

"Me too, I listened to him a lot of Chopin a while ago."

"Potato chips, can I eat them?" The clear nails exposed by the red cuffs face the half-open yellow package.

"Yes, yes." Wen Cheng replied with a smile.

Liu Zhen came to the table and picked up the bag of potato chips, looked back at Su Meng's dissatisfied little mouth, walked to Su Meng's side with an apologetic smile, and pointed the opening of the package at Su Meng, but was pushed away by Su Meng.

Liu Zhen reached out and took a slice, put it to his mouth and chewed it slowly, put the yellow package back on the table, withdrew his hand and licked his fingers. Su Meng picked up the potato chip package on the table again and put it in Liu Zhen's hand.

Wen Cheng suddenly found that there was only a wooden chair in front of the desk in the room.

"I'm going to move the chairs......" he said.

"No need, Wen Cheng, let's just sit on the bed." Su Meng said with a smile.

Liu Zhen glanced at Su Meng lightly, sighed and sat on the edge of the bed, cocked Erlang's legs and hooked the slippers and swayed gently, while Su Meng solemnly took off the slippers and knelt on the bed virtuously.

"I'll make you tea, Su Meng, what are you drinking?" Wen Cheng stood in front of the two girls leaning on a chair, leaning forward slightly like an old housekeeper.

"Plain water will do." The cuffs of the blue school uniform are politely placed on the legs.

"That...... Where's Yoo Jin?"

"Whatever." Liu Zhen looked around the room and said lightly.

Wen Chengfeng was an ordinary long, tall glass, the teacup was not insulated, and Liu Zhen put the potato chips on his lap, holding the thick bottom of the cup with one hand and pinching the wall of the cup that was not hot with the other.

Su Meng was boiling water, holding the cup with both hands clasped together.

"It's unpleasant." Liu Zhen took two sips, bypassed Su Meng and put the cup on the bedside table.

"Is it unpleasant? This is the dragon well before the rain." Gu Wencheng spread his helpless hands.

"I only drink the first day."

"It's really not a good hospitality, eldest lady, next time I'll buy some tea for you."

Liu Zhen pouted and snorted.

"Forget it, Liu Zhen, if people are kind, don't embarrass him." Su Meng said while holding the cup.

Liu Zhen pursed his dry lips, picked up the teacup with both hands, and slowly pursed.

"Two beauties, can you tell me what the hell is going on?" Gu Wencheng sat on the chair with his hands on the back of the chair.

"Declare in advance, don't ask me anything about magic." Liu Zhen replied quickly.

"Is one sentence okay?"

"Say."

"Aren't all magicians chanting spells?"

Liu Zhen quickly showed an impatient look, looked at the tea in his hand and the potato chips on his legs, and tightened the corners of his mouth, his little feet stopped swaying unbridledly, and his legs politely said together,

"Well, when you say chanting, it's just a traditional chant in the narrow sense. Thinking about the sound such as sad something, it is useless to increase piety, honorifics such as who to respect, the use of source resonance, it is very time-consuming, the quotation and input language behind it are a bit useful, as for the praise words that follow behind, it is all nonsense. In short, chanting is just a small skill to increase resonance, and this is the age of scientific programming magic."

"The Age of Wizardry?" Gu Wencheng sat up straight, listened eagerly.

"It's just a means of converting material energy, but science hasn't developed enough to understand the law of femtometer-level conversion, so it still needs to rely on human brains and the special constitution of some people. Besides, modern magic doesn't have that many effects, it's like a pistol, isn't it, Biu is over in one fell swoop."

Liu Zhen pursed his lips and made a gesture to point at Gu Wencheng.

Faced with the eldest lady's sudden cold humor, Gu Wencheng swallowed his saliva. Su Meng also looked at Liu Zhen with a surprised look at the boiled water in his hand, but fortunately it didn't squirt.

Ryu Zhen set the cup aside, grabbed the potato chips and chewed them at a loss.

A small table lamp silently passed the awkward atmosphere in the corner.

"Okay, stupid, I'm thinking about the case right now, so I've saved you, can I help sort it out together." Liu Zhen said.

Wen Cheng found that the green tea in Liu Zhen's cup had been drunk, and only the tea leaves attached to the wall remained.

"I'll pour tea." He got up, took the teacup from Yoo Zhen's hand, and when he came back, he dragged the bedside table in front of Yoo Jin and Su Meng and placed the teacup on it.

"Ryu Zhen," Wen Cheng sat down and asked, "Is the case you are talking about a recent disappearance?"

"Nonsense." Liu Zhen replied quickly.

"But it stands to reason that it should be handed over to the police, why should it be handed over to a magician like you?"

"There are too many mechanical dogs, the police force is already seriously understaffed, and there was an exchange of fire a few days ago, and several police units have lost contact."

Can't even the police...... Wen Cheng sighed.

"And according to the committee's investigation, some of the disappearance scenes have left traces of black magic, so now the case is officially taken over by the magician."

"I see." Wen Cheng nodded and said.

"It's said that the magician took over, but there is no doubt that the biggest responsibility lies with me." The girl sighed.

Wen Cheng looked at the pouting lips of the table in front of him and showed helplessness, and he didn't know how to answer, so he continued to listen.

"Let's go back to the case," Ryu Zhen said, "although the accidents are scattered, most of them are late at night, and the people who are killed are passers-by, and there is no crime in the house, and there is usually a clear shadow."

"In other words, the mechanical dogs will only operate in the dark side." Wen Cheng concluded.

Liu Zhen didn't answer, and continued to talk to himself, "The problem is the motive, such a large-scale random disappearance case, naturally the possibility of deliberate murder can be ruled out. Of course, it's possible that the real target is hidden among many random targets." Liu Zhen said to himself, put down the remaining half of the potato chips, licked his fingers, took out a piece of tissue paper and wiped his mouth.

"Are they all mechanical dogs?" Gu Wencheng, who sensed the heaviness of the matter, stared at Liu Zhen.

"Sort of, I didn't see any other murderers." Liu Zhen replied.

"Excuse me...... I might want to ask an unrelated question, we magicians ......," the boy asked tentatively.

"We're magically working so soon, you really don't think of yourself as an outsider." Liu Zhen gave him a blank look and asked, "Go on."

"Our mission is to save them, isn't it?"

"Saving people? You're sick, aren't you?" Liu Zhen suddenly said, "Of course I can't save it!"
