Walking into this bare canyon, I don't know if it's the scenery or the buildings, there is always a suffocating sense of depression around!

It seems that it is not only Lao Xiao Tou who feels this way, even Yan Lao Er and Jian Nu, who have always liked to quarrel, have become dumb at this time.

The valley slopes at a thirty-degree angle, stretching towards the surface, and the incredibly steep mines on both sides confine the senses to a small space.

When I looked up, I saw three blood-red characters: Xuan Field, written in ancient calligraphy and calligraphy, each stroke was flamboyant and domineering, as if it was about to kill at any time.

Between the ground and the mountain, a huge arched mine cave appears in a deep passage.

From here, there are a number of stone steps at each step, and the terrain falls all the way down the stairs, as if they lead deep underground.

There are lighting beads on the walls along the way, and the light is very close to the sunlight, which is very comfortable. It's just that the chill that hits people can't feel the temperature in this moment.

At the end of the first stone staircase, a stone chamber appeared in front of it, blocking the stairs behind it, and only a small open door shimmered softly.

Facing the stone room, the sword slave's expression was a little strange, her steps hesitated, and a fish face was full of thoughts.

"What's important hidden inside?" Lao Xiaotou never likes to guess other people's thoughts, not to mention that her fish face is also very accessible.

But! This time, Lao Xiao Tou was guessing her expression, hoping to read her thoughts.

The sword slave sighed, shook his head, and said, "This is the special training room!" ”。

"This first stone room is the feeling and speed of training killers.... There is only one purpose, and that is to train the killer to use the super technique of killing with one hit" As the sword slave explained, the four of them had already walked to the front of the stone chamber, and from the window, they could see countless live targets hanging in the air.

"Empty? There was no one inside," Yan Lao Er glanced around the stone room with a wary face.

"It's strange, it seems that something really happened in the mining area, and even the Xuan Field Killer came out" The sword slave's eyes also glanced inside, and said in a surprised tone.

"Let's go, we have to rescue the ugly girl before they put down the chaos" Old Xiao Tou's nervous mood could finally be relieved, and he first led the Yan brothers towards the stone room.

"Be careful" The sword slave saw that Lao Xiao had already entered the stone room with one foot, and hurriedly reached out and dragged him back.

At the moment when Lao Xiao had just left the door of the stone chamber on his toes, a gust of wind and rain blew in the stone chamber. It's just that these raindrops are not water, but hidden weapons like steel nails. There are so many hidden weapons that weave through the small space, and if someone were to stand in the center, they would definitely be shot into a honeycomb.

"Holy! There's even a mechanism buried in it? Old Xiao touched a cold sweat embarrassedly, if it wasn't for the sword slave who pulled him just now, he might have been nailed into a hedgehog now.

The sword slave walked over, stretched out his hand and patted Lao Xiao's shoulder gently, and said with a hint of sadness in his tone: "They are used to punish the Xuantian killer."

"Every year, there are more killers who die in the special training of the special killing, even more than they go on assassination missions.... Every Occult Killer enters the Killing Room, as if he has experienced a life and death catastrophe, and the slightest carelessness will kill him."

"It seems that it is very difficult to be a killer in this world," Lao Xiao Tou stared at the sword slave's fish-faced face with a tangled expression, and shook his head helplessly.

"Swordsman, what is the use of what you have been talking about for a long time, how can we get through these stone chambers?" Yan Lao Er rushed over impatiently and questioned the sword slave.

"You are so kind, go and try it" The sword slave glanced at Yan Lao Er and sneered.

"Just try, I'm afraid of you?" Yan Lao Er was stunned and went to the stone house, but was grabbed by Yan Lao.

"Yan Lao Er, do you want to die?" Boss Yan turned around and clasped his fists at the sword slave and said, "Please also ask the sword slave brothers to help show the way."

"Actually, I don't have a good way, if I want to break through the stone room, the only way is to knock them down before the traps are triggered, and you can clear the level smoothly," the sword slave explained with a bitter expression.

Seventeen targets, in the blink of an eye, all hit! Is this simply a strong man's difficulty? Old Xiao Tou and the Yan brothers couldn't help frowning together.

"I'll try it first" Lao Xiaotou thought about it, and finally mustered up the courage to walk to the door, holding his breath and staring at a dozen hanging targets.

"Master, why don't you let the sword slave try it first, and then you break in" The sword slave stopped Lao Xiao with a worried expression.

"I want to try" Old Xiao shook his head and walked into the stone room without hesitation.

At this time, his heart was as calm as water, his pupils constricted, and his eyes were focused on the dozen or so hanging live targets. A scorching aura of flame in his palm was spinning rapidly.

Whoosh! Old Xiao Tou made a move, his palm was almost to an astonishing point, and the afterimage stopped in everyone's eyes along his movements.

This speed is already close to the limit of human reaction speed, and Lao Xiao Tou has an epiphany at this time, as if he is in a new perception of nature and himself.

Sou! One live target fell to the ground, followed by the other, and sixteen of them all fell to the ground, and at that moment, countless sharp whistling sounds were heard in all directions.

With the exclamation of the two Yan brothers, Lao Xiao Tou also clearly understood that the mechanism had been triggered, and his figure hurriedly fell to the ground, and then backhanded the last flame towards the seventeenth live target.

Bite! Bite! There was a row of hidden weapons behind Lao Xiaotou, and he also escaped the first round of hidden weapon bombardment without danger.

Soon the ground began to rise, roofs were falling, and an even bigger storm of hidden artifacts was brewing.

Click! The ground and roof snapped to a halt with a series of gear clashes, revealing a passage above the wall that could only be walked by.

"Master, enter the passage!" The sword slave shouted with an excited expression on his face.

"But what about you?" Old Xiao Tou was still hesitating, he looked back at the entrance, and found that the entrance behind him had long been closed, and it turned out that there could only be one door open here, or an exit, or an entrance.

"Master, the stone chamber can only break through with its own strength, and no one can break through with other people's strength," the sword slave hurriedly explained.
