At ten o'clock in the evening, the van with the words "Caution! Haunted House Identification" was slowly parked on the side of the road.

In front of the road is an old tunnel with double arches and four lanes.

Above the tunnel, a few mottled handwriting can be vaguely seen.

"Thousand Valley Tunnel".

"Whoa!"

As the car door opened quickly, a young man in sportswear with a golden oil head and a six-pointed star engraved on his temples emerged from the inside with the momentum of a beast coming out of the cage...

The two passers-by who happened to pass by the car thought they had encountered a "gang of van sacks, kidnappings, kidnappings, humiliating, dismembering corpses", instantly unlocking their genetic locks, burning their lives, and speeding away.

Immediately behind the criminal-faced youth who got out of the car was a demure girl in a red and white witch costume, a long cloth bag on her back, and a sword on her waist.

The two people standing together with a completely different imposing manner are the genius slayer of the level [II], Tori Yumayumi...

And under her guidance, only the "legal" spirit removal activities can be carried out, the level [zero] trainee spirit removal, Araki Sosuke.

"Sure enough, this glowing 'arrow' points in the direction of the tunnel..."

Standing on the side of the road, Sosuke Araki unzipped his sports bag and confirmed that the faintly bright symbol on the picture scroll was facing the tunnel not far away.

At the same time, an extra-long antenna suddenly protruded from the top of the white van.

"Then, let's test the communication first... Hey, Araki-kun, Tori Yu-shi, this is..."

A man's thick voice suddenly appeared in the headphones worn by the two of them.

"Hmph, I don't even know the common sense of using encrypted codes for communication! A task of this level is really not something that a layman like Hacker Lu Dou can command..."

Before he could finish speaking, he was interrupted by the woman's frantic voice: "Cough, this is the 'Wall of Maria', the Survey Corps, can you hear me?"

"What kind of strange encryption code is this, and the code name of 'Hacker Lu Dou' has already explained all my details clearly...Sister, I'm still debugging, don't rush...Zi!! !!"

"Damn, you actually pulled my line! Even though I'm just a driver today, I have to match the sense of participation I deserve..."

"That, I said, I heard it very clearly..."

Sosuke Araki, who was on the side of the road, sighed, took off his earphones, and protested to the two brothers and sisters who were arguing in the van: "Please, we are still outside the car, don't abuse the communication channel to quarrel in the place next door, This will only create repeated echoes and tinnitus..."

"Oh, sorry sorry..."

"Survey Corps, you go to the tunnel, and continue the test on the way..."

The rear window of the car rolled down, revealing Mai Hanyu's bright and pretty face.

At the moment, she is wearing headphones, sitting cross-legged in the back of the car that has been converted into a "temporary command room" with computers and communication equipment installed.

Hearing her words, the two obediently walked towards the tunnel entrance more than 200 meters ahead.

"Hey, Hanyu-san, how are you, can you hear me now?"

After a short walk, Sousuke Araki asked in the communication channel.

"During the mission, please call me 'Maria's Wall'... Well, yes, the latest type of communication base station that Lesson 9 borrowed, said to be resistant to strong magnetic interference, is really a hard product..."

"Damn, what's the reason, just 'take off' to see clearly and then go back! 』

In the communication channel, there were melancholy thoughts of Hanyu Mai.

"What about the picture, do I need to adjust it?"

Taking the other party's complaint as a reply, Sousuke Araki continued to confirm.

"Move the 'Eye of Reality GOPRO version' a little to the center of your chest... Yes, that's it... Let's go."

When everything was ready, the two quickened their pace and soon came to the "Thousand Valley Tunnel" with dim lights and an old appearance.

Until midnight, the Qiandagu Tunnel, which is usually crowded with traffic, was empty and looked very cold.

"Spiritual."

Standing at the entrance of the tunnel, Yumako Tori slapped the burning talisman paper on the ground.

A circle of blue-colored spiritual power ripples spread out along the inner wall of the tunnel with her as the center.

"Near the tunnel entrance, there is no sign of resentment activity for the time being..."

After careful sensing, she shook her head at Sousuke Araki next to her.

"The 'Wall of Maria' has been received. No abnormality has been found in the external observation of the tunnel. Please continue to move forward..."

"Sure enough, it is impossible to feel the turbulent undercurrent after the twists and turns just by rubbing against the door. 』

In the headset, there is a response from Hanyu Mai, who is in the van and is observing the outside of the tunnel through the "Eye of Reality GOPRO Edition".

"Mr. Araki, then let's go into the tunnel."

From the van's position, the figure of the two walking side by side gradually turned into small black dots and disappeared, as if being swallowed up by the abyss-like tunnel.

...

The Sendagaya Tunnel is a four-lane double-door tunnel with a length of about one kilometer built for the Tokyo Olympics held in 1964.

Secretly, this old tunnel, which looks ordinary to tourists, has another identity.

One of the famous paranormal places in Shinjuku.

That's right, Shinjuku, which is located in the "Yin and Yang" where the grievances of all Tokyo are gathered, is naturally more than one magical place.

As soon as you enter the tunnel entrance, you can feel that the temperature has dropped a few degrees compared to the outside.

"It is said that during the construction of the tunnel, there were often resentful spirits at work, which caused repeated delays in the construction period."

Even though it was late at night in early autumn, Sousuke Araki could clearly see the white fog like orchid in the mouth of the girl.

"In the end, it was Yin Yang Liao who personally supervised the work, and it was completed in time for the opening of the Olympic Games..."

"The Olympics?! It's not been forty or fifty years... until now, haven't the resentful spirits been completely eradicated here?"

While listening to Kotori Yumayumi's introduction, Sosuke Araki looked curiously at the various graffiti of unknown meaning on the inner wall of the tunnel.

Most of the tunnels and inner walls of overpasses in Tokyo will be decorated with colorful works by street graffiti enthusiasts according to the regional culture and characteristics, and they will even be regularly covered and updated.

However, unlike other tunnels with themes such as animation, trends, slogans, and sentimental culture, the graffiti on the inside of Qiandagu Tunnel is a chaotic, simple black and white line, which is very strange.

"Since the tunnel was built, the Yin Yang Liao and the Spirit Eliminator Association ~lightnovelpub.net~ will come here regularly to clean up the resentful spirits that appear from time to time..."

"Even so, there are still pedestrians who often see strangely dressed figures here, and there are even many hand and footprints on passing vehicles, or horrific grimace hanging down when passing through..."

Tori Yumayumi shook his head helplessly and pointed to the top of the tunnel.

"Don't talk about these unusual rumors, even the seepage at the top of the cave, after many waterproofing works, still can't be completely solved, and the reason can't be found at all."

On the top of the tunnel, there is a lot of water condensed, dripping down from time to time.

"Moreover, in recent decades, dozens of motor vehicles and hundreds of pedestrians have disappeared in the nearby area, all suspected to be related to this tunnel."

"Tsk tsk, the rumor of this tunnel is really mysterious."

Listening to Yuma Yumori's words, Araki Sousuke simply took off his blindfold and looked inside the tunnel carefully.

"Wow, as expected of a place in Shinjuku, known as the 'Yin and Yang', where you can rank first..."
