The city at dawn gradually woke up to the crisp sound of birdsong.

The unthawed sunlight spilled thinly through the clouds, enveloping the city in a gray-blue air, adding to the chill.

Gu Fangyan actually woke up very early, but today's temperature suddenly dropped for some reason, making him tremble for a long time before he shivered out of the quilt.

As soon as he pushed open the door, Ling Chenxuan was standing straight in front of the living room window in a daze, a cold pure black tight shirt faintly set off his bamboo tendon-like upper body.

The contours of his entire body seemed to melt into the cold morning sun, and his black hair was like a stone washed and polished by the waves countless times, reflecting the star-like streamers.

"Hello?" Gu Fangyan greeted cautiously.

"Huh?" Ling Chenxuan glanced at him with a sideways face.

Gu Fangyan glanced at his watch, "It's not even six o'clock...... Did I disturb you to enjoy the first rays of the morning alone?"

"Are you awake too?" Ling Chenxuan said softly.

"Woke up from freezing. Gu Fangyan grinned, "Big brother, don't you know that your back just now is enough to make a girl's blood gush out, why is it a person who is in a daze? ”

"Xuanjie. Ling Chenxuan slowly looked into the distance, "The Xuanjie rang again just now, and it was near here." ”

He looked through the window and saw in the distance the old walls full of creepers, one after another, and the old cat was clinging to the eaves and stretching its waist, licking its paws, turning over and disappearing.

"But where is it......" his voice was as low as a lullaby chanted by a river under the moon.

Gu Fangyan trembled and turned on the switch of the water dispenser with a water cup, the red light of the heating turned on silently, he yawned and sat down on the sofa.

"Are you unreliable or not, how do you feel like a dragon ruler that fools people. He looked at Ling Chenxuan's banner-like silhouette and said faintly.

"Perhaps, it is indeed an old thing, in today's terms, it is outdated. Ling Chenxuan exhaled lightly, "But it worked for my mission, at least for now." ”

"Then where do you think you're looking for, just know that around here, you have to have a general direction. ”

"The perception of the Xuan Ring...... Seems to come from underground. Ling Chenxuan said expressionlessly.

"I'll lean on ......" Gu Fangyan sat up in a sleepy dream, "What do you want to do, let me remind you that the local people don't dare to move this residential area, you don't want to dig three feet into the ground and demolish this place, right?"

Gu Fangyan couldn't help but think of a middle-aged uncle wearing elegant leather gloves and holding a small shovel and flashlight squatting on the ground to measure the geology, but this time it was estimated that a handsome young man driving a heavy bulldozer was bulldozing an aging residential area with an expressionless face.

The picture is really strong...... But if that's the case, where will I live in the future? Gu Fangyan felt that he should stand on the side of justice now, he struggled to get up from the sofa, "Big brother, don't tell me that you exorcists really did it......"

Ling Chenxuan turned around and looked at him coldly, with words written all over his face, "I'm sorry, my purpose is to do whatever it takes to achieve the end...... At this time, Gu Fangyan suddenly felt that the person in front of him had become stranger, as if he had become the cold-eyed and knife-raising exorcist before.

Gu Fangyan moved the corners of his mouth, and just as he was about to say something, there was a brisk knock at the door.

"I'm going to open the door......" Gu Fangyan hurriedly slipped away.

He walked briskly to the entrance and unscrewed the doorknob.

"Hello morning!" a fair-skinned and delicate face broke in from the edge of the door, and Cheng Xinuo looked into the door.

"Hello......" Gu Fangyan couldn't help but take a step back.

"Wake up so early, two-dimensional boy, to be honest, I still wish the person who opened the door for me was a senior. Cheng Xinuo pretended to sigh softly with regret.

"You can disrespect me, but please respect my name......"

"Okay, okay, Xiaoyan is early. Cheng Xinuo smiled and rubbed his fluffy hair, and his slender five fingers kneaded his hair into a perfect chicken nest with a twist.

…… really has the demeanor of a sunny big sister, obviously Cheng Xinuo's age is only about eighteen years old, but Gu Fangyan suddenly felt that he had become a crying little brother in an instant.

But he was actually quite happy that she came, she was like a clear sunshine everywhere, and the temperature in the entire living room suddenly rose from zero degrees.

"Why did you come here so early?" Ling Chenxuan looked at her with a slight frown, and Cheng Xinuo stuck out his tongue in disdain, "I said I was going to come to comfort you, of course I have to be closer to you at all times." ”

Ling Chenxuan directly ignored her nonsensical answer.

“…… Okay, don't be so fierce...... I just don't want to go back to the North City branch so early, you know that when I go back, I check the points and assign tasks, and I finally managed to get a small vacation, of course I hope it will be a little longer. ”

Cheng Xinuo straightened his chest unconvinced, "Anyway, I also got up so early to break the record to assist you in carrying out the task, and I reluctantly gave up the two-meter-eight big bed, don't underestimate me." ”

Gu Fangyan thought to himself, didn't you just say that you wanted the vacation to be longer? Obviously you are joining in the fun, but it is called voluntary assistance, even I know that you exorcists can't cooperate!

Ling Chenxuan's eyes gradually calmed down a little, "It's coming, just now the Xuanjie moved again, and the source of perception came from underground." ”

"Ah, are you sure you didn't sense me? I did come up from downstairs. Cheng Xinuo replied with a confused face.

Ling Chenxuan shook his head, "It can't be you, the exorcist usually suppresses his yang energy magnetic field to a negligible amount in order to hide his identity, and he will hardly be perceived by the Xuan Ring from such a distance." ”

Indeed, the yang energy magnetic field emitted by an exorcist walking on the street is completely different from that of an exorcist with a knife and a murderous aura of yang blood, the latter is like an invisible tornado, constantly spreading a strong coercion in all directions.

"Damn, magnetic field, are you a solar machine, what is the situation with the positive energy magnetic field?" Gu Fangyan was also stunned.

Cheng Xinuo glanced at him, "You're still a senior in high school, do you know that living things will also emit magnetic fields around, but the categories they belong to are different, the human body's magnetic field is related to blood flow, we are yang blood, of course we can emit yang energy magnetic field, didn't the teacher teach you in biology class?"

Gu Fangyan cried with a sad face, "I'm just a liberal arts student...... wronged"

The next moment, Ling Chenxuan, who was originally contemplative, suddenly raised his head, "I understand, it turns out that I have always ignored a simplest but most critical issue. ”

"What?" the two of them looked confused.

"Cheng Xinuo's words just now suddenly reminded me that we were actually on the second floor all along. Ling Chenxuan said with a serious face.

“…… Huh?" Cheng Xinuo blinked. It felt like an old man who basks in the sun every day suddenly falls into deep thought, and then solemnly announces with a solemn face that the sun has always risen in the east.

"We've been on the second floor all along, since the source of the yang energy that Xuan Jie senses comes from underground...... Is it possible that the Solstice Antiquity is downstairs?"

Cheng Xinuo raised his hand and scratched his hair, "But senior, how can there be an antiquity buried downstairs, not to mention that it is a thing of the sunshine thousands of years ago, how can it not be buried dozens of meters underground?"

Ling Chenxuan looked straight at Gu Fangyan, "Is the first floor inhabited now?"

"I didn't ...... It's been idle for a long time. ”

"Let's go down and have a look. Ling Chenxuan said coldly, turning around and about to go downstairs, Gu Fangyan hurriedly stopped him, "Wait, wait, that place is just a messy utility room, I haven't cleaned it up for a long time, it's all some old textbooks and useless daily necessities that I use, how can there be Zhiyang antiquities?"

"Your identity is suspicious at the moment, and I don't have enough reason to trust you completely, and besides, I can't let go of any clues that are even outrageous. Ling Chenxuan turned his head and stared at him coldly, "Let go." ”

Gu Fangyan felt that the blood in his whole body was slowly surging towards his brain, but the Xuan Ring in Ling Chenxuan's hand did not react.

He slowly let go of the hand that was holding Ling Chenxuan's clothes, and silently watched Ling Chenxuan go downstairs.

Cheng Xinuo patted him on the shoulder comfortingly, "That guy has such a temper, just get used to it." ”

…………

The door on the first floor had not been locked, Ling Chenxuan gently pushed the door open, and the sunlight shone directly into the room along the balcony, and there was a heavy dust floating in the light, which had indeed not been cleaned for a long time.

There are only a few dry leaves left on the empty balcony, as if they will turn to shreds with a gentle breath, and it is hard to imagine that this place was once full of people.

All the furniture has been removed, and the hall, which was not very large, is now extremely lonely, and even the air has lost its vitality. In the corner, there are piles and piles of old textbooks that have not been turned over in a long time, a rotten plastic washbasin, a mess of paper boxes, a handbag made of cowhide, and a bamboo bench next to it.

Overhead, there was the sound of footsteps descending the stairs, and Cheng Xinuo and Gu Fangyan followed from behind.

"You see, it's really nothing. Gu Fangyan shrugged his shoulders stupidly.

Ling Chenxuan didn't answer, but walked straight to the suitcase.

"Who left this?" he crouched down to inspect the leather box, which was just a very common cheap item, with a somewhat damaged appearance, the leather had faded in some places, and the whole box showed a heavy sense of age, as if if if you would find some old photos and old military uniforms as long as you opened it.

Gu Fangyan stared at the box for a long time, as if he had reunited with his old friend after a long absence.

"This ...... This is my dad's belongings, and someone else sent them back from out of town. Gu Fangyan felt that his throat was a little astringent, as if he had blocked a stone.

Memories of the past rushed like a galloping horse, kicking his nerves with a dull ache, that the box was indeed the man's, the last thing he left to the family.

It is said that the man asked a friend to send it back from Beicheng, and the box was tossed and turned home, but the man never came back.

It should be the man's last thing, I don't know what is stored in it, but Gu Fangyan ruthlessly threw the box directly into the corner, and finally abandoned it here.

Why didn't he open it? Gu Fangyan himself didn't know, as if as long as he opened it, the last secret left by the man would also dissipate, in that case, the man would really be completely dead in his memory, even if the so-called secret might just be the man's spare clothes and razor.

So he was scared and chose to run away.

"Can I open it?" Ling Chenxuan asked softly.

“…… Whatever. Gu Fangyan only felt that the strength of his whole body had been drained.

The box just lay silently in place, but it seemed to hold a key that was enough to open a world.
