The hoarse chirping of night crows sounded, and the shadows shook in the deep mountain forest.

The dark night sky, mottled rocks, dead leaves, and a pool of stagnant water in the forest with some green algae. Right next to that, there was a rotting tree trunk lying down, and from its thick outline, it was clear that this rotting wood was once a large tree with lush foliage.

It looked like an oak tree.

"I, how could I ...... here"

Next to the small pool, Gu Jun looked around suspiciously, and covered his head in severe pain, is this an illusion? Dream? No, it doesn't look like ......

He was actually here, he could feel it.

"What's going on? Xianyu and I returned to the Dongzhou base, went to the Psychiatric Building, went to see a patient named Zhong Huili, and then ...... Xiao Huili had a seizure, cursing at me, and my whole body twitched with a headache, is it a stress reaction...... And then ......"

Gu Jun's eyes flashed with some intermittent and chaotic memory images, muttering to himself, shouting by himself, pushing away the people who were in the way...... I told Wu Shiyu, who was in a hurry, not to follow, and Cai Zixuan not to follow, not to follow......

"Am I going crazy acutely...... Vehement? Mania? ”

His heart sank, it was very likely, his physical and mental condition was different from before.

He has biological changes in his brain, and his mood has been in a state of ups and downs lately, as if he could have a PTSD attack at any time......

And this time, maybe there is also the spiritual effect of that cursed strange sound.

"Where is this?"

Gu Jun looked at the hazy surroundings, full of rotten trees and dead branches, lifeless.

Such a place, he had no doubt, was a haunt of the dark forces and their followers. Perhaps it was here, around this pool of stagnant water that stenched with the stench of corruption, that the cultists performed some unknown ritual in the night, reaching out their sinful hands to the innocent children.

He looked for himself, there was no cell phone, walkie-talkie or other things, but he was still carrying the carry-on backpack, which did not contain many things, the five Carlop dissecting instruments, and the watercolor painting of Xianyu...... There is nothing that can connect him to the outside world or make him figure out where this is.

Through the gaps between the branches and leaves of the trees, the night sky was dark and starless, and when the branches and leaves were swayed by the cold wind, the dark clouds remained still.

Gu Jun stood in place for a long time, still not moving around, listening intently to the surroundings, there was a strange and low sound of mountains and forests, but there was no call......

"I must have escaped from the medical department base and scurried into the surrounding mountains. But in that case, I wouldn't have been found until now, the base is surrounded by surveillance, sentry, patrols, and how fast can I run? Find a police dog and catch up with ...... all at once"

Gu Jun didn't think that other people really listened to him and didn't chase after him, and the environment here was not like around the base.

"Ah......h

I heard the exclamation of the crowd in my head, "Be careful, be careful!" Wu Shiyu pounced on him and pulled him, but he pushed him away. He seems to be ...... What was summoned using spells, is it the Seven Secrets of the Earth, the Fifth Secret Entity Dire...... Baiaki?

This was his guess, because he had read the text manuscript of the Fifth Secret, but he had not read the Secret Codex, and he had not cultivated to that extent.

There was no memory to confirm his suspicion, he just seemed to have summoned some alien creature, and then flew away from the base.

Could that be some kind of heterogram? Gu Jun was at a loss, not sure that this was near the base, or even in Dongzhou.

"How can I still use spells? My mental power is in shambles...... But when a person falls into madness, it's a different state. ”

Gu Jun was thinking about it, when suddenly a strong wind blew, and the trees and weeds around rustled, and he turned his head to look at it, as if he saw a figure scurrying through the forest over there. He frowned, looked around, and then looked into the pool, which seemed to be rotten flesh except for the reflection......

Standing here was not an option, he looked for footprints in the dirt under his feet to see if he could find the direction he had come from.

But it seems to be ...... That's where the alien creature landed, and the rotten flesh was what it exploded.

In the cold night breeze, faintly, tinkling, tinkling...... It's the sound of the piano.

"Piano, how can there be a piano in this barren mountain outskirts...... Am I here where the enemy wants me to be......"

Is this one, invited?

"Who are you?" Gu Jun asked softly, taking out the Carlopp scalpel and holding it in his hand.

The sound of the piano became clearer and clearer, and the tune was very beautiful and pleasant, like the quiet words spoken by this mountain forest.

But Gu Jun stared at himself and didn't let himself listen to it, and walked in the opposite direction to the sound of the piano, and walked into the gloomy mountain forest. However, he walked more than ten meters on the rotten black soil, but he felt closer to the sound of the piano......

He immediately turned and walked in the other direction, but after a short walk, the sound of the piano was still getting closer.

When he tried all directions with the waterhole as the midpoint, he determined that the sound of the piano was like a ghost, like a shadow.

Gu Jun knew that this was someone's territory, and where he went or what he did, it would not affect the imminence of the piano.

And he walked with his senses, ten, twenty, fifty...... The sound of the piano resounded through the woods, and he stepped out of the dense forest into an open woodland, and in front of him were some ancient and huge oak trees, twisted branches that formed a grotesque sight, it was an oak forest.

Just over there, by an oak tree, there was a crumbling black piano covered in moss, and a figure sat in front of it.

Gu Jun's eyes suddenly condensed, what is that, is it a human being......

The figure was only draped in ragged rags, swollen like a giant corpse, except for a pair of hands that were withered like white bones, and the slender ten fingers were constantly playing on the piano keys. Judging from the outline, it did look like a human being, a withered male.

At this time, the figure slowly cast a glance here, his face was also old and swollen like a corpse, and his eyes were full of pain.

Gu Jun's heart was cold, and the more he listened to this piece, the more he felt that the style was very similar to some of Mozart's tunes he had heard in the past few days......

His head thumped again, and he heard a chuckling female voice ringing through the woods.

"Dear brother, are you here......"

The oak grove was full of shadows, and the swollen old man under the tree in front of him continued to play the piano.
