"Squeak!"

The door was very heavy, and under Yun Yang's force, the heavy and thick door in front of him was slowly pushed inward.

The door opened, and a wind blew from nowhere, and behind the door was a long and narrow road, which was not very bright.

With the sound of "squeak", the doors closed together again.

Yun Yang took a deep breath, calmed his mind, and walked forward, the more he went forward, the stronger the wind became, and the gravity also increased, with Yun Yang's current cultivation, he was only a little reluctant, and he was upset for a while, and there was faint sweat on his forehead, and he couldn't help but be secretly frightened in his heart.

"I haven't been gone for long, but I can't bear it."

In the corridor, a figure moved slowly, and after walking for about a quarter of an hour, more than a dozen large or small corridors appeared in the corridor, scattered like human blood, deep into the darkness in the distance.

"Which path to choose? Which one did the xenos choose? ”

Standing in front of many paths, Yun Yang also made a difficulty.

"Now that we've come here, let's keep going." Yun Yang chose the middle path.

"Woooooo The sound that had been heard at first had disappeared since entering the passage, and now it was louder than what had been heard outside.

After walking for I don't know how long, Yun Yang began to get tired of the monotonous scenery on both sides of the road, and he was upset, it was too depressing.

Just when Yun Yang wanted to give up and return, a huge stone appeared in front of him, and a fist-sized pipe was inserted into the stone, and the whining sound in the tunnel came from the pipe, and the sound was like crying.

The sudden appearance of the stone blocked Yun Yang's way forward, and if he wanted to move forward, he had to move the stone away, Yun Yang used his greatest strength, but the stone remained immovable, no matter how hard he tried, it was useless.

Retract your hands and set your eyes on the tube above the stone.

The whole stone is unremarkable, there is only one tube stuck in it, and this tube must have some connection with the stone.

The pipe was rusty, broken, and damaged in many places, it should have been eroded for a long time to become what it is now, Yun Yang looked at the pipe silently, and the next moment, he gently put his hand on the pipe, and a black mist emanated from his slender five fingers, and finally wrapped around the pipe.

Yun Yang then withdrew his palm, looking at the tube expectantly, when he first saw this tube, the large net of three-color energy in his body was intertwined, and the black energy in it began to stir, if it wasn't for the other two-color energy to suppress it, I am afraid that it would not be out of his control.

He hadn't encountered this situation before, and it was obvious that the black energy should have something to do with this tube, but he didn't know the origin of the black energy at all, and he didn't know if it would be useful to do so.

"Poof!"

The next moment, the tube was shrouded in black mist, and in an instant, a strong black gas burst out, as if a person who had been sleeping for a long time had finally woken up, and at the same time, the tube began to turn, and after a week of rotation, it began to reverse again.

"Click!"

When the pipe was reversed, a sudden sound sounded in the stone, and then everything stopped.

Yun Yang took a step back and waited quietly.

Half-sounded, a dull rumbling sound sounded, and a crack suddenly appeared in the middle of the originally intact stone, and the stone was split in two, slowly moving to the side, and in an instant, a hole was revealed behind it.

Yun Yang inhaled deeply, at this time he was a little excited and a little afraid in his heart, but deep in his heart, the biggest emotion he occupied was curiosity, no longer paused, and walked over in great strides.

"We've come here, no matter what lies ahead, we have to face it."

Behind the stones, there is still a deep road, and the road is very dim, and you can barely see the road.

Yun Yang was cautious along the way, the road was long and tortuous, and he walked for a long time, and suddenly, a ray of light appeared in front of his sight.

"Is it the end of the tunnel?"

Yun Yang walked forward excitedly and briskly, and vaguely saw a huge stone chamber in front of him.

Gradually getting closer, Yun Yang saw the situation in front of him clearly, in front of him was a stone chamber in a circular shape, on the opposite side of the stone chamber, there was a corridor extending inside, and the light was emitted by a large night pearl in the stone chamber.

Yun Yang scanned the stone room and found that there was a stone table in the stone room, and there were four stone chairs around the stone table, which were covered with dust, obviously no one had been here for a long time.

Yun Yang continued to walk forward, this time he didn't walk long, he saw a huge smooth stone wall, there was a road on both sides of the stone wall, leading to an unknown place, under the stone wall, there was a bluestone platform, and there was a human skeleton on the bluestone platform.

Yun Yang thought for a while, and then walked towards the left Yongdao, this Yongdao is no different from the road when he came, monotonous and lonely, and soon Yun Yang saw a pitch-black gate, the green grass under the gate is secluded, although it is not the singing of birds and flowers, but it is also unique.

Yun Yang walked all the way, all of them were as silent and monotonous as death, and now when he saw the faint green grass, his mood suddenly relaxed, and the whole person came to life.

The fragrance of grass is refreshing, Yun Yang greedily breathes the mesmerizing fragrance of grass, it has been a long time since anyone has been here, why is there still a blooming grass plant? Yun Yang couldn't think of a reason.

Above the rich flowers and plants, the dark gate is engraved with two big characters of "medicine sacrifice", the gesture is vigorous, and the dragon and snake go straight out, and there is a tendency to come out head-on, roaring in the sky.

Yun Yang walked over, the door of the medicine sacrifice opened under stress, effortlessly, the moment the door opened, a strong fragrance of pills came to his face, making his breathing appear to stagnate for a short time, the smell of medicine was too strong, and his body couldn't help but take a step back.

After a while, when the smell of medicine was no longer strong, Yun Yang walked into the stone room.

The stone room is very dim, only some simple furnishings, what attracts attention is a stone bed located in a corner of the stone room, the stone bed is surrounded by potted pills, the pills are crystal clear, even the veins on the branches of the pills can be clearly seen, and even the liquid flowing in the branches can be seen.

The sap flows on the branches, gurgling and moving, which is very attractive.

The rich medicinal fragrance in the room is emanating from these pills.

There is a small tripod on the top of the stone bed, the style of the small tripod is simple, the rust is mottled, the tripod is full of green soil, the soil exudes a bright light, the small tripod is reflected quite mysteriously.

There is a deep hole in the middle of the green soil, obviously this Xiaoding has also planted pills, it should have been taken away by someone, but it is not clear, why the other party only took the pills, not Xiaoding, this Xiaoding is obviously not ordinary.

Yun Yang picked up Xiao Ding, but the moment Xiao Ding left the stone bed, the potted plants full of pills around the stone bed instantly wilted, and after a while, they completely withered, and there was nothing left.

Yun Yang stared at everything that had just happened.
