Villa angrily walked out of the side hall and went straight out of the palace.

Mo Lin heard him shouting loudly as the guards assembled, and followed him to the palace gate to suppress the mutinous wolf cavalry.

Ye Wuxian stayed in the side hall and did not come out. Mo Lin estimated that his human guards would soon come in, so he hurriedly slipped out through the other exit.

As soon as he went out, he saw the human guards swarming in, and one of the generals who took the lead whispered in a low voice, and soon the guards came out of the palace and stood on guard all around.

I don't know what the situation is on the other side of the city, but Mo Lin no longer puts his mind on that side. He considered the conversation between Fang Cai Ye Wuxian and Villa, and decided to go to the Black Dragon King's palace to have a look.

The palace of the Black Dragon King should be the palace above that is pitch black and does not light up at all, among the three palaces, the one is the largest, more than five times the other two, otherwise it will not be able to fit the huge body of the Black Dragon King.

It's just that in the middle of the night, the palace is pitch black, and there is no sound at all, as if it is isolated from the world, making people feel that there seems to be some secret hidden in it.

Mo Lin sneaked away, and soon came to a distance of a hundred steps outside the palace, but suddenly stopped. He leaned down and took a closer look at the ground.

Sure enough, a metal wire as thick as a hair was buried under the floating soil, very hidden. Once stepped on, it will trigger a mechanism connected to a metal wire, which may be a piercing bell or a row of deadly poisoned arrows.

If Mo Lin is not an ink practitioner and does not know the art of the mechanism, he is afraid that he has already been tricked. However, since he found that there were mechanisms ambushing around the palace, his vigilance was high, so he quickly found more than a dozen large and small mechanisms.

These traps surrounded the palace, and unless they had wings on their bodies, they could not cross the distance of a hundred paces. And Mo Lin also doubted that in the dark palace, there were also some sharp eyes, even if there were birds that wanted to get closer, they would be buried under some powerful ambush.

These mechanisms are very powerful, but Mo Lin doesn't pay attention to them, he bends down, his fingers twist lightly on the metal wire, and his hands and feet are ready.

For an engineering artist, these institutions are like an interesting exam, and for a good student like Mo Lin, who is quite talented in engineering, the difficulty of this exam is inevitably a little low.

He walked forward as if he were strolling through the courts, tackling the mechanisms and keeping an eye out for movement in the palace.

Thankfully, the guards in the palace trusted these mechanisms and did not have patrolling guards. Mo Lin easily destroyed all the mechanisms along the way and came to the front of the palace.

This is a palace of great magnificence, more domineering than the other two, standing lonely in the night, like a furious beast.

In the dark palace, there seems to be a secret hidden that cannot be told, and it smells of decay. Only when he got closer did Mo Lin find that all the doors and windows were tightly closed, and they were covered with dust, and it seemed that no one had been in or out for a long time.

Mo Lin came to the door, which was a thick and somewhat heavy wooden door, the original color was no longer visible, because a layer of floating ash had fallen on the door.

Mo Lin leaned down and gently wiped his fingers under the crack of the door, his fingers were covered with dust, judging from the thickness of the ash, this door probably hadn't been opened for several years.

"Could it be that the Black Dragon King is really not here, otherwise how could his palace be so dilapidated?" Mo Lin said in his heart.

In any case, you have to go in and take a look, and you might find some clues.

However, Mo Lin didn't plan to take this door, he circled around the palace, chose an inconspicuous corner, removed a window, and then turned over and jumped in.

Landing on the ground of the palace, Mo Lin looked around, it was pitch black inside, and he couldn't see his five fingers. Fortunately, Mo Lin's eyesight is amazing, and he activates the subtle energy of the light point of the wind in the darkness, and the five senses of the body are released, and after a while, he can see in the dark.

The palace was also in ruins, dusty everywhere, and a thick layer had accumulated on the ground, and it was as if you were stepping on a soft carpet.

"How can this be ......" Mo Lin was puzzled, looking at the appearance in the palace, the Black Dragon King should indeed not be here.

He hesitated for a moment, and decided to go in and have a look, after all, he had already arrived here, and he was always a little unwilling not to investigate one.

Walking in the palace, Mo Lin did not deliberately suppress the sound of footsteps, and some of the floating dust brought by his footsteps was slightly raised, making a light rustling sound.

The palace was huge, and Mo Lin turned left and right, and it took a while to come to the main hall in the center.

Mo Lin had seen the bones of the red dragon and the green dragon, and had also fought against the white dragon himself. The bodies of the three dragons were not of average size, compared to the green dragon's body being the smallest, followed by the red dragon, and the white dragon's body being the largest.

According to Mo Lin's estimate, the growth time of the dragon is probably different, and the body is not the usual size.

The white dragon has lived for five or six hundred years, and it is naturally the largest. The green dragon was slain by Stirling four or five hundred years ago, and it may not have grown up at that time. And the red dragon was killed between them, the size of the stature and in line with this speculation.

According to this speculation, the black dragon and the white dragon should be the same size. Before coming to the central hall, Mo Lin had always wondered if there was a place in this palace that could accommodate the huge body of the black dragon.

But when he came here, Mo Lin suddenly realized.

At the top of the main hall is a huge vault nearly 30 meters high, and the center of the vault is a transparent round hole that can lead directly to the outside. Judging by the size of the round hole, it shouldn't be a problem for the dragon to fly in and out.

And the main hall itself is more than 100 steps in circumference, judging from the decoration, it must have been a magnificent and magnificent palace of magnificence back then, but unfortunately now the pearl is covered with dust, giving people a sense of desolation.

"At this scale, it can probably fit the body of a dragon." Mo Lin walked around the main hall, leaving a row of faint footprints.

The main hall was empty, and in the center of the hall, there was a huge dragon chair, which occupied almost one-third of the space of the hall.

The dragon chair was full of dust, Mo Lin walked closer, gently stroked his hand, and a light breeze swayed, sweeping away all the dust.

Under the dust, the original black color of the dragon chair was revealed, and the chair was carved with various patterns, as well as some floating pictures.

This work 1 6k exclusive text version debuted, may not be reproduced without consent, excerpts, more of the latest and fastest chapters, please visit 1 6k.! Mo Lin looked down and saw that these pictures were continuous pictures, the first pattern depicted many werewolves and humans fighting some monsters that could spit sand and stones, the second was a huge crack in the earth, and the third was a black dragon drilling out of the ground and soaring straight into the sky.

There are more than a dozen pictures in a row, depicting the story of the birth of the black dragon and the defeat of the sand demon. Mo Lin had already heard what Mrs. Hua had said, but he still watched it with relish, and he could be regarded as understanding the true history of this continent.

After looking at these floating pictures, Mo Lin stroked the black chair, guessing the story of the Black Dragon King ascending the throne as emperor here, uniting werewolves and humans, fighting against sand demons together, and building a huge empire, and couldn't help but feel a lot of emotion.

More than ten years ago, what happened and where did the Black Dragon King go?

Mo Lin sat on the chair and felt cold, it seemed that this wood was very peculiar.

Feeling the coolness coming from the chair, Mo Lin felt very comfortable, and he silently looked around every corner of the hall, guessing where the Black Dragon King went.

"Could it be underground?" I thought that the black dragon was a giant dragon bred by the Earth Dragon Ball, and when it was first born, it also drilled out from the depths of the earth.

I haven't seen you for fifteen years, have you gone back underground?

Mo Lin felt that this guess was very likely, so he got up and walked around the main hall, looking for clues.

When his gaze fell back on the huge chair, Mo Lin's heart suddenly moved, and he leaned down and looked under the chair.

The chair is carved from a large tree trunk and is intricately crafted, with the entire lower part of the chair looking solid wood. Mo Lin reached out to knock, and heard the soft sound of "dong dong".

"It's empty inside......" Mo Lin smiled, finally found some clues, hoping that this was the key to solving the mystery.

Now that he had found something strange, it was difficult for Mo Lin to find the mechanism, and he fumbled around it, and found that a raised decoration on the back of the chair was a little strange.

Grabbing the raised decoration, Mo Lin exerted a slight force, but only turned it slightly, and made a "squeak" harsh grinding sound.

Mo Lin knew that this was a long time ago, and the iron used in the mechanism was rusty. The palm of his hand slowly heated, channeling the psionic energy down, forming a diaphragm between the rust to avoid friction.

Turning it down again, it was much easier, the mechanism was twisted one hundred and eighty degrees, and with the rotation of the mechanism, the whole chair "clicked" and turned horizontally.

When the chair stopped, a huge hole had appeared in front of Mo Lin's eyes, and when he looked down from the hole, there were still lights.

"It's weird." Mo Lin became interested, he was very naughty when he was a child, and he was very curious about everything. These days, there is too much pressure and responsibility on my body, but I don't have the chic and free time of the hour, and I live happily.

Seeing the strange cave underground at this moment reminded him of the underground Dragon Palace in Chixian Shenzhou, and he didn't know what mystery was down there.

There are no stairs in the cave, but a large square hole, and the light comes from the corner on the left.

Mo Lin jumped down and landed steadily at the bottom of the cave more than ten meters down, in the corner on the left, a spacious corridor led to nowhere, on the walls on both sides of the corridor, there were holes dug out, and there were everlasting lamps placed in it.

There was a mechanism on Mo Lin's side, and he reached out to break it, and the bench above his head snapped back to its original position, blocking the hole again.

It was pitch black overhead, and there was only the splendor of the corridor in front of him, and Mo Lin stepped in, leading to an unknown mysterious world.

Mo Lin stopped in front of the lantern and looked at the jar full of lamp oil.

A lot of the oil in the jar has been burned, and Mo Lin estimated that these lanterns have probably been burning for more than ten years.

The time was about the same as the number of years when the Black Dragon King had disappeared, and Mo Lin was overjoyed for a while, feeling that he was closer to the end of the mystery.
