They placed the long stick across the hole, and the ends could be stuck in the two grooves, and it was very firm, and the stick itself could bear enough weight.

They tied the rope to the wooden stick and pressed the long stick down a few times, but it was indeed not moving.

They are not very clear about the following situation, but obviously the secret is below.

With what they could carry now, Mo Junye lit the torch and slowly walked down the rope.

As for this rope, they can only stay here for the time being, and they still need to use it when they go up.

There was still a little dark and cold inside, but fortunately enough air.

The bottom is more spacious than the entrance of the cave. They illuminated it with a torch and found that it was a circular enclosed space.

What appeared before their eyes was another stone door.

However, this stone door is a bit different. It is just a thick stone with no pressing place and no gaps...

"Let's go ahead..." Mo Junye said.

This is the beginning, don't worry.

The same is true for Yoon So-hyun, he has come anyway.

Holding the torch, they swung around this small space for a while and found torches hanging on the walls.

After lit the two torches at the door, the space became brighter.

Not far from the stone gate, there is a round platform that looks very old and has some spider webs and dust.

There are three statues on the round platform. When you get closer, you will see that they are also Dragon Kings, but the colors are different.

Yin Su-hyun was a little excited and placed the statue of Dragon King she accidentally picked up in the vacant position of the round platform.

However, there was no movement in the stone gate.

She knew that she was thinking too simple.

She took down the statue and put it on again, but it was still the same, without any change.

Mo Junye was watching and was helping to discuss it.

Yin Su-hyun thought, could it be that the location was wrong?

"My husband, how do you feel in direction? Do you know which side is the east?" Yin Su-hyun asked.

Mo Junye made a little judgment and immediately said, "This is the place..."

This powerful sense of direction made Yoon Su-hyun smile again.

"We are really a match made by heaven..." She couldn't help but sigh.

Mo Junye also accepted it happily, it was necessary.

"What's wrong with knowing which side is East?" Mo Junye asked.

Yin Su-han said: "I have a guess. These four dragon kings can be seen by the color, including the east green, the south red, the west black, and the north white. Then, according to the law of going up, north, south, left, west, right and east, it will be easy to determine which side is the east. Put them in their respective positions, and maybe there will be effect..."

Mo Junye understood that different colors represent different directions.

These dragon kings should be placed in their respective positions.

Yin Su-hyun carefully placed the statue in the direction and order he identified just now.

After they put it on this time, they really heard Carrara's voice again.

The middle of the statue was suddenly opened.

They walked over and looked, and a metal ring lay there quietly.

Yin Su-hyun carefully took off the metal ring, but the stone door that was still motionless suddenly began to lift up.

It turns out that the mechanism is here, and it is quite exquisite.

Mo Junye did not forget to complain: "If Xu Huai and Ruogu were allowed to leave here, I would probably not be able to collect their bodies..."

Yin Su-hyun also sighed: "Mingyu and Mingyue are the same..."

At this time, the four people above kept sneezing.

The captain of the guard also asked, "What's wrong with you?"

Humeng thought of a very safe excuse: "My nose wants to sneeze when I see the sunshine..."

As a result, Ruogu made up a knife: "You are so shameless..."

They were bickering and heard someone say, "Be careful, people are coming..."

Yin Su-hyun was not wrong, and these people were not allowed to give up.

The assassination probably didn't expect that this was a mission without going back.

Below, Mo Junye and Yin Su-hyun had already held up the torches and entered the door.

There seems to be another compartment inside, and it is still the same as before, with a firewall.

After they ignited the fire wall, they saw that it was empty.

There is no pattern on the wall, but something is wrong.

Yin Su-hyun was still thinking about where the metal ring just now should be placed.

So, she kept searching for whether there were any similar grooves or something.

The first thing they noticed was a wooden door.

Mo Junye walked over and pushed him a few times, but couldn't push him away.

There is a jack on the door, which seems to be left for the key.

Yin Su-hyun gently knocked on the wooden door and changed positions, but no abnormalities were heard.

She thought that this metal ring must be useful.

After looking around for a week, they were by the door, but still found no clues.

Mo Junye immediately changed the search range and carefully searched for any possible traces on the surrounding walls.

Finally, in a very inconspicuous place, he saw a groove, which happened to be the shape of a ring.

Yin Su-hyun sighed that every time he was so inconspicuous, he would miss it if he was not careful.

When I found that groove, I admitted that I was a little ecstatic, and I thought, there should be nothing in front of me.

Time waits for no one, and I don’t know what else will happen later, so they can’t waste it.

Yin Su-hyun quickly kept himself rational and put the metal ring in.

This time, no sound was made next to him, but the ring itself was shining.

Yin Su-hyun observed that there were several patterns on the surface of the metal ring, namely black, white and red, among which black are three small bars, white is two, and red is four.

They didn't know what this was for a moment.

Just as they were struggling, the ground rumbling again.

A square platform suddenly rose on the entire ground.

They walked over and found a box on the table.

Mo Junye took the box over, looked at it carefully, and then shook it for a while.

There was something ringing inside, and Yin Su-hyun immediately thought that it must be the key.

"You should be familiar with this box..." Mo Junye smiled relaxedly.

"Well, Luban lock, just like the Luban lock that my uncle asked his aunt to return to his grandmother, but this is simpler..."

Yin Su-hyun took it and said directly.

Now they say that this is not discovered by my uncle, so they no longer believe it.

But, what does this have to do with Jiuchen?

There are three colors of inserts on the small box: black, white and red, which reminds Yin Su-hyun of the pattern on the metal ring just now.

With a smile, she gently fiddled with the inserts according to the number of bars of several colors.

Sure enough, the box opened easily, and in the box, it happened to be a rusty key, lying there quietly.

The key fell to the ground and their mood became even more relaxed.

Yin Su-hyun picked up the key, went directly to the wooden door, and then tentatively inserted the key into it.
Chapter completed!
