Medical Concubine Chenghuang

Chapter 693 Strange Keys
This is a small cave, and the air in the cave is very humid. The cold wind blows from nowhere, and the flames of the fire are flickering and dimming.

Being in such a weird place, if you are a timid person, you will probably be paralyzed by fright at that time.

Meiniang gritted the fire pocket with her teeth, turned over and climbed to the shore, and lit the oil lamp on the cave wall.

Tongues of fire jumped, and the familiar fragrance came to the nostrils again.

"The taste is the same... So, the designer on the ship is the same person as the designer here..."

The curiosity in Yunbei's heart was even heavier, and he watched Mei Niang walk back with charming eyes.

Not long after, a rather familiar stone wall came into view again.

Yun Bei chuckled and stood with arms folded.

She didn't know what was behind the stone wall that surprised her.

Could it be another special world? !
As always, Mei Niang pressed several mechanisms on the stone gate, and with the sound of the mechanism turning, the stone wall rose upwards.

Unexpectedly, there was still a stone corridor behind the stone wall, and lamp oil mixed with corpse oil was still burning on the walls on both sides.

After entering this tunnel, Yunbei sniffed unconsciously.

"The air here is quite dry..."

Compared with the first course, there is obviously less moisture here.

"But it's not right... the more you go in, the more humid it should be? Why is it getting drier? And... where does the wind and air come from?"

As it continued to go deeper, another stone wall lay in front of Meiniang.

In the same way, Mei Niang opened the stone door again, and just like before, the fire dragon on the wall rose instantly.

Yunbei thought about it in his mind, the distance of a passage is at least 50 meters, and the distance of two windings is at least hundreds of meters.

And because she is underground, she no longer has the concept of direction, nor does she know which direction is east, west, north, south.

I don't know whether it is the ground or the lake above their heads at this time.

Regardless of whether it was mud or lake water, if a landslide occurred anyway, they would only be trapped to death.

Mei Niang finally stopped in front of a stone wall again, calling it a stone wall is a little bit reluctant, but calling it a stone gate is more appropriate.

Because on the top of this stone wall, there are rough patterns engraved. The lines have been blurred for too long and cannot be seen clearly. It can only be roughly seen that this is a depiction of a plant.

And among the patterns, there are two door knockers, on which hangs a big fish-like lock with a strange shape.

Mei Niang's fingertips flicked lightly on the big lock, brushing off the dust on it, revealing the original color inside.

Only then did Yunbei see clearly that the big fish-shaped lock turned out to be a golden lock.

On Jin Suo's body, there is a groove, and strange patterns are carved in the groove.

It's just that this pattern is a bit strange, it doesn't look like a convex surface on ordinary decorations, but is sunken in.

When Yun Bei was wondering what kind of carving style this was, Mei Niang had already taken out a pendant from her bosom.

The golden light is brilliant and the shape is strange.

With just one glance, Yunbei instantly understood.

The golden lock hanging on the door is indeed a lock, and it is also a combination lock. Those concave groove patterns are the patterns of the combination lock.

And the pendant on Mei Niang's body is the key to unlock the lock.

The key is engraved with a raised pattern, judging from the direction of the pattern, it is the same as the pattern on the lock.
