As soon as I entered the corridor, there was a cold breath in my face, and the snow-white tiles on the walls on both sides reflected a temperatureless light, giving people the feeling that they were entering a cold hell.

"It's so cold...... Egyptian royal sister hugged her arms and trembled slightly, and Zhang Luo immediately noticed that his water-stained combat uniform was quickly turning into a hard ice lump.

"Can you turn on the propulsion?" He asked Darov, who was walking in front, questioning.

Hearing this, the Russian looked back at him and said helplessly: "I really convinced you, using power armor propulsion for warmth, this is the first time I have heard of it." ”

He was complaining, but Darov still turned on the propulsion system, and the two nozzles behind him immediately spewed flames, Zhang Luo and Haser hurriedly came to the side of the flame and began to dry the clothes on their bodies.

"Don't move, we'll all turn into barbecue if you move." Zhang Luo said with a smile.

"Then hurry up, it will automatically eject when the power becomes larger." Darov complained.

Since now was not the time to leisurely roast the fire, after drying the clothes on his body a little, Zhang Luo asked Darov to turn off the propulsion device of the power armor, and the three of them continued to move forward, heading towards the deep passage.

After walking forward for about a hundred meters, a square metal sign appeared on the wall on the left, Zhang Luo stepped forward, turned on the translation function of the Executioner's Eye, and stared at the Russian text on a white background and red letters, which was obviously the name of the facility:

Donrosk Underground Energy Research Institute.

"Well, it doesn't look like this is a groundwater treatment plant." Zhang Luo smiled.

-- This is the first time he has heard of such an institution as the Underground Energy Research Institute. After all, in today's solar, wind and hydropower industries, it seems that there is little use in studying underground energy. Aside from the extraction of minerals and oil, few people think about going underground. Not to mention building a research institute in such a place.

"Have you heard of this?" Hazel asked Darov beside him, after all, this strange place is somewhat similar to the underground pyramid of the Monster Authority.

"No, the Authority tried to investigate the city of Donrosk back then, but the fighting was so fierce that it lost three people before anything could be found, so it immediately withdrew." Darov shook his head.

Hearing the words of the great exorcist, Zhang Luo didn't say anything, just looked at the inside of the passage, the closed heavy metal door.

The dark gray metal door is painted with scarlet lines, and the two doors are engaged in a gear-like way in between, making them more like the heavy protective doors of military bunkers than ordinary facility gates.

It is obviously difficult to use brute force to destroy such a heavy protective door.

However, on the wall to the right of the protective door, there is another ordinary small door. There was no sign or anything like that, but it was like it was written in five big words, "I am the control room".

"You should go there and open the door, right?" Hassiner frowned slightly.

"It always feels like a trap." Zhang Luo nodded.

That being said, he strode towards the small door. After all, this unknown situation couldn't be better for him.

The three of them walked to the door, and before they could open it, they heard heavy breathing from inside, sounding like they were made by a large animal:

"Whew...... Whoop......"

"Do they have rhinos in it?" Zhang Luo said with a smile.

"Shhhh Hasher held up a finger to his lips and carefully pressed his body against the wall.

Under the gaze of Zhang Luo and Hassin, who were standing on both sides of the door, the Russian in power armor stood in front of the door, took a deep breath, stretched out his hand with black power armor gloves to grasp the doorknob, and then twisted it slightly.

With a friendly creak, the black iron door was opened, and strangely, the moment it was opened, the sound of breathing that seemed to come from the room disappeared without a trace.

Darov observed the situation inside, and then finally breathed a sigh of relief:

"There's nothing wrong with it."

Seeing that the Russians were about to stride into the house as he spoke, Zhang Luo hurriedly shouted: "Wait a minute! "But it was too late.

Darov, who had stepped into the room, turned his head, and a muffled voice came from under the power armor helmet:

"What's wrong? Let's take a look at ......"

Before he could finish his sentence, he was interrupted by a large hand sticking out from the wall.

Under the gaze of Zhang Luo and Hashiner, a large gray hand protruding from the wall strangled Darov's helmet of power armor, which looked like it was made of concrete, and powder was constantly falling from it.

At the same time, dozens of distorted human faces of the same color as the walls suddenly grew on the wall, and the gray faces showed expressions of incomparably painful expressions, and their mouths were wide open and they let out hoarse cries of terror:

"Get out of here, get out of our institute!"

"Anubis is up there, what is that......" Hazin exclaimed.

"This house is alive." Zhang Luo, who had encountered a similar situation in the Nightmare Theater, said in a deep voice.

- Although I don't know if it's the will of the house itself, or the consciousness of the people who are melted into the walls, this consciousness is undoubtedly preventing them from entering the room and trying to kill Darov who has fallen into the house.

But...... That great, well-armed exorcist wouldn't be killed so easily.

"What the hell ......"

Darov roared angrily and activated the "Black Fire" power fist in his hand, and a powerful uppercut directly smashed the arm that grabbed him!

"Ahhh Dozens of faces embedded in the walls opened their mouths wider and let out howls of pain.

Darov gruffly grabbed the severed concrete arm that was still on his head and ripped it off and tossed it aside. After recovering his vision, he was taken aback by the scene in front of him:

"What's going on, haunted?"

"Smash the wall to pieces." Zhang Luo, who was "maliciously watching" in the back, reminded him.

To destroy a living house, just blow up its body and solve the problem. There may be many living houses that have been disposed of by the demolition team. But now is not the time to think about these inconsequential questions......

"Bang!"

Darov smashed the inside wall facing the door with a punch, and then saw a dark red object that was pulsing inside, so he pulled it out and smashed it on the ground.

With the destruction of the "heart" of the house, the faces on the walls and the severed arms immediately turned into dust and fell to the ground, and this terrible room finally returned to normal.

"I almost scared Lao Tzu to death...... "Darov looked down at the "heart" that was still spurting blood under his feet, and couldn't help but curse. Even a veteran exorcist like him had never seen anything like it.

"That's why I warned you not to go inside." Zhang Luo also walked into the room as he spoke, standing still in front of the bookshelf leaning against the inner wall, and looking at the few notebooks inside.

I took down the outermost notebook, and saw a line of scribbled small letters on the yellowed cover: "Research Record, 1980." ”

"Well, now let's see what the hell they're doing here, shall we?"

While speaking, Zhang Luo had already opened the notebook, turned the page with his name written on it and went directly to the text, only to see the first page written:

"May 1, 1980 was a memorable day when we finally moved into the completed Donrosk Underground Research Institute to conduct research on the development of underground energy under the leadership of Dr. Ivanovich......
