Chapter 523 Secret Door
Exploring the immortal cave is different from exploring an ordinary cave. To be honest, it is similar to when Olde went to find the Demon King's Ring. There are many things that cannot be explained by science.

Yang Yiyi's side seems to be a very normal martial arts, but after all, it is one of the planes in the multiverse world, so it is normal to see some things that do not conform to the style of the plane.

Apart from anything else, the style of the psychic laser gun in Yang Yiyi's arms is different from that in the local area...

The three were surprised and delighted at the sudden appearance of the cave.

I was happy because I finally opened the mechanism, but I was shocked because I didn't know where this hole led to.

They were heading downwards, but they wanted to return to the surface...

"Brother Li, shall we go in?"

"Be careful, go down and take a look, there is no other way."

Who knows how big this underground cavity is. Yang Yiyi and the others have been walking for half an hour and still haven't seen the end. If they continue walking, they don't know how long they will reach it. Since there is a mechanism that can be opened, it should be okay to go down and take a look.

Don't forget, it is clearly written on the stone slab in front of the door that the treasures left by the Fairy Qinglian for those who are destined to receive them are placed here. It is equivalent to a place of inheritance.

In this case, all its mechanisms cannot be designed to eliminate invaders. They are more like a test. It should be okay to go down and take a look.

After getting Li Chengxi's approval and waiting for Wu Shaoyi to copy down the music score, the three of them gathered around the cave entrance and looked down.

Oddly enough, you can clearly see the stairs extending down at the entrance of the cave, but you can't see what's deeper inside. Even if you use emergency lights, the darkness will not fade away and you can only see the steps.

This is obviously not a natural situation, it is obviously the result of some magical effect.

The three of them had a brief discussion. Yang Yiyi, who was the most resistant to attacks, walked in front, Wu Shaoyi, who was not as easy to move on the stairs as the other two, walked in the middle, and Qin Yan was responsible for covering the rear.

This is a standard adventurer team assault formation, with warrior, priest, mage, and thief arranged in that order, but there is no priest.

But on second thought, it is true that there are some, for example, Li Chengxi can play the role of a nanny and deliver potions...

The stairs were not too steep, so Yang Yiyi took the lead and walked down. As the height decreased, the darkness around them seemed to surround the three of them like some kind of sticky liquid. However, due to the presence of the emergency lights, a circle of light was created through which they could clearly see the steps under their feet.

Not knowing how deep this staircase was, Yang Yiyi felt like she had walked for almost an incense stick of time, but it also felt like she had only walked for a short while. Her sense of time seemed a little confused.

Then Yang Yiyi saw that the steps not far ahead disappeared and a flat rocky ground appeared, and she realized that she had finally reached the end.

With her feet on the ground, Yang Yiyi raised the emergency light, trying to illuminate the surroundings so that she could see what was going on.

At this time, some tiny dots of light appeared above everyone's heads.

It looked like glowing moss, but the amount of glow began to increase at a speed visible to the naked eye. After a while, it changed from a few dots to a large area, like a starry sky.

The light was appearing rapidly and imperceptibly, and the brightness was gradually increasing. When the three people came back to their senses from the spectacular scene of the starry sky, they found that they could see clearly around them even without the emergency lights.

They were now in a huge vertical tubular cave, with a large number of stalagmites visible around them and some protruding rocks scattered on the surrounding rock walls.

Surprisingly, the stairs they had just walked down had disappeared, as if they had never appeared at all.

Simple illusion cannot explain this at all. It is like space magic. Going down the stairs is like traveling through time.

"Look over there, is there a door?"

Yang Yiyi's words attracted Wu Shaoyi and Qin Yan who were looking around. They looked in the direction Yang Yiyi pointed and saw a double stone door hidden among the stalagmites.

As soon as they saw the door, the three of them immediately went over.

The stone door was carved with lotus decorations, green mountains and waters, and auspicious patterns of dragons and phoenixes, but it was locked. Yang Yiyi tried to push the door but couldn't move it at all.

The three found something that looked like a keyhole in the door. It was a groove that could fit a palm-sized ball. There were densely packed tiny grooves in the groove, and it looked like it could be turned. "No, I can't open this kind of door."

Qin Yan knew at a glance that this kind of door could not be pried open at all. The keyhole was too complicated. Even the thieves from the Sixteen Villages would have a headache seeing it.

"It's just a stone door. Let me come."

Since technical skills don’t work, then use brute force.

Without waiting for the two to reply, Yang Yiyi rushed forward and struck them with two clanging palms, and wanted to follow up with an iron head skill to directly shatter the stone gate.

Not to mention the palm power, Yang Yiyi's iron head skill can break granite. The head is fine, but the stone is broken.

But after two palms, Yang Yiyi just pointed her head at the stone door, and saw a flash of green light on the stone door. Before Yang Yiyi could exert any strength, she was pushed out by the light and almost fell down.

"Don't be impatient. There is a spell on this thing. It is difficult to break it with brute force alone."

Yang Yiyi was indeed reckless. When Li Chengxi was looking at the introduction of items at the gate, Yang Yiyi decided to start her own business.

The detailed information reads 'a stone door with a sealing charm attached', and the description below reads 'a specific key is required to open'.

"Brother Li, can you just break it? Just like you broke the seal before."

"It's hard to say without trying, but it's best not to force it."

Assuming that all that Yang Yiyi and the others have encountered so far are just tests from the Green Lotus Fairy, then finding the key to open the door must also be one of the tests. Breaking it directly might lead to something bad.

This is equivalent to using cheats in a multiplayer game, and the GM will definitely not let it go.

Speaking of finding the key, judging from the position of the keyhole, it should be a palm-sized, spherical or hemispherical object.

The three of them looked around after hearing this, but didn't see anything similar.

Li Chengxi also pressed the alt key and looked around, but there was nothing.

This is really puzzling, where is the thing?
Just when I was wondering, Qin Yan suddenly said:
"I think I found it."

She pointed upwards:
"Up there."

The three of them looked up. The most eye-catching thing was of course the glowing moss at the highest point, as if the stars were blinking. But if you look closely, you will find that under the stars, there is a dark thing, like a black hole.

It was actually the shadow of some real object, blocking the phosphorescence of the glowing moss.

If you look at the size more carefully, it might actually be the key to open the door.

The question is how to get up there.

Qin Yan looked around again:

"There is a barely accessible place to stand every few steps on these rock walls. This is probably not a coincidence."

"But that's too steep..."

Not to mention that it was straight up and down, this slope was definitely not a height that could be easily jumped up by a light function, not to mention that the key was too high, and it might be more than ten feet high by visual estimation.

If you don't step firmly and fall down, even if you have martial arts skills, your brain will burst.
